5 Reasons Why You Should Get a Gutter Guard Installed

You certainly need a gutter to keep water from entering your roof, basement, and house. But why does it need a guard? 

You might think a gutter guard is just one of those expenses that you could do without. 

Well, we’ve got not one, but five reasons to convince you otherwise. Read on!

  1. Keep Debris Out of the Gutters

Gutter guards will prevent your gutters from getting clogged up with twigs, leaves, pine needles, and other debris. You do not have to spend your weekend cleaning the gutter anymore!

  1. Protection for Your Home

Here are some ways that a gutter guard protects your home.

Mold and Mildew

The moisture and organic waste in your gutter provide the perfect environment for mold to thrive.

With less debris clogging up your gutters, the chances of mold or mildew growing in the gutters and your house are reduced.

Not only do mold and mildew seep into your roof but also your basement and, eventually, the air. Leaving mildew to grow in your house is risking the respiratory health of your family, especially those prone to allergies and asthma.

Water Spills

Not installing gutter guards often leads to water spills, which cause roof and wall damage. Water spills after accumulating in your gutters due to clogged debris, but it’s not the spill that’s a cause of worry.

All the water that’s accumulating or spilling onto your roof can lead to rust damage. Now that’s a bigger repair and much costlier than installing a gutter guard.

Without a gutter guard, it’s not just the integrity of your gutters at stake but also that of your house.

  1. Prevent Fires

Several leaves and twigs from those neighbouring trees end up in your gutters. Stuck long enough, this debris tends to dry up and become the perfect setup for a wildfire.

Yes, that’s what happens when some lighted embers enter your open gutters.

One way to prevent this catastrophe?

Keep the debris and the lighted embers from entering your gutters with the help of a gutter guard.

  1. Pest Control

Open gutters are an attractive sight for pests and a breeding spot for insects.

Open gutters are also the reason why you haven’t been able to get those pests out of your backyard.

Think of it, an open gutter is a perfect spot for pests with the accumulation of debris, dirt, and water. Once the debris clogs up the gutter, it becomes a safe place for the insects to lay their eggs. Any place that is a breeding ground for pests becomes a hunting ground for wild animals.

You wouldn’t want to risk your life by cleaning those gutters yourself, would you?

  1. Save Money on Maintenance and Repair

Gutter guards reduce the amount of debris entering your gutters. By keeping your gutters clean, you’re also ensuring they function optimally for a long time. This reduces the costs of gutter maintenance and repair.

Clogged gutters can weaken the integrity of your gutters, causing them to rust, and eventually cost you all your savings.

Why worry about such problems when you can easily prevent them by installing gutter guards?

If you’re getting them installed this season, then who better to call than Gutter-Vac?

Our expert team will install the right gutter guard for your house so you’re not busy booking maintenance services for a long time.

Why You Should Get Your Gutters Cleaned This Holiday Season

Apart from getting them to look great to start the New Year, cleaning your gutter can also protect your property from damage in the long run. 

Want more reasons to convince you to get your gutters cleaned this holiday season?

Here are a few to consider.

Avoid Unexpected Repairs During The Holidays

Unclean gutters can overspill, clog with debris, rust, or leak. They may also get structurally damaged because of all the load the debris is putting on them.

A water spill can also damage the foundation of your house by seeping into the walls.

Now that could lead to a nasty surprise during the holidays. And we think the only kind of surprise you should be getting this holiday season is a surprise gift. After all, you don’t want to be the one stuck taking care of gutter repairs, missing out on all the festivities.

Plan the cleaning work now so it’s out of your way for the holiday season.

Protect Your House From Fires

Christmas, summer school holidays, camping, and bushfire season are all synonymous with the holiday season.

Most holiday season occurrences aren’t dangerous, but some certainly are. Bushfires can start with no human intervention. All it takes is some source of fuel and enough dry vegetation. The former is sitting in your gutter in the form of those dry leaves and twigs.

Clear them out now to protect your home from fire damage.

Enjoy the Holiday Season

It’s the time of the year to get out and enjoy the weather and festivities. Don’t you need your outdoors to be clean and safe for your family to roam around freely?

Dirty and clogged gutters will cause the water gushing through them to spill over to the roof and outer walls. This creates water puddles at the bottom of the wall. These puddles can, in turn, seep into the basement and breed mosquitoes.

Thinking of attaching exterior Christmas lights on the gutters?

Consider cleaning your gutters first.

Prepare for Autumn

By the time you’re done enjoying the holidays and taking down those decorations, fall will come around. And with it, an inflow of leaves that make their way to your gutters.

If your gutters are already full of debris, this addition can clog them up for good.

 Want to avoid such a mess?

Clean your gutters now and rest up for the next two seasons straight!

Cleaning your gutters all by yourself is a risky task and one you don’t want to undertake right before the holidays. There’s a lot more you need to do inside the house as well.

Then why not call the professionals at Gutter-Vac?

Our professional team uses only the best tools to clean your gutters so you can rest and enjoy the holiday season.

We also provide a free report and evaluation so you know the status of your gutters better. In case there’s a serious and urgent problem with your gutters, an evaluation will bring it to light.

While most of our efforts at maintaining our gutters are directed towards keeping and cleaning fallen leaves from them, many nasty critters can find their way into our gutters and make them their home.

Why is it important to keep insects away from our gutters? Infestations can lead to many issues like clogged gutters, blockages, drainage issues, and more. To avoid this, you need to regularly clean and maintain your gutter. 

If having insects in your gutters is a concern of yours, then you’re in the right place. In this article, we talk about 5 incredible ways you can keep insects and other creatures away from your gutters.

#1. Regular Cleaning 

There’s no avoiding the need to regularly clean your gutters. Invest in a good broom and clean your gutters frequently to prevent build-us. Since insects thrive on moisture, ensure that your gutters have a chance to thoroughly dry after cleaning.

#2. Fix the Cracks

Insects like cockroaches, mosquitoes, ants, spiders, and termites use every crack and crevice that they can crawl into to create a nest inside your gutters. In addition, cracks provide an entry point for litter and waste to accumulate. 

To address these issues, cover the bigger holes with metal patches and the smaller holes and openings with heavy-duty sealants. 

#3. Install Gutter Screens

Gutter screens come in a variety of types and materials. Depending on your needs and preferences, you can opt for plastic screens, steel screens, perforated aluminium screens, and more.

Your Guide to Rain Gutter Cleaning and Maintenance

Water can do an immense amount of damage to a house, and the only way to prevent that is to ensure that diversion systems like rain gutters are kept clean. It’s an unpleasant chore and often one that falls last on our “to-do” list. But it’s important to get it done nonetheless. 

Let’s take a closer look to understand “why,” shall we?

What Damage Do Clogged Rain Gutters Do?

Unclean gutters accumulate debris that continues to build up over time, clogging the drains further. With clogged channels come a whole host of problems such as:

  • Stagnant water turns into a breeding place for pests
  • Dry but clogged gutters attract critters and rodents
  • Structural damage to your roof, gutter, and drainage system

While postponing gutter cleaning may seem like a great idea at the time, in the long run, it will bring you nothing but an endless list of expenses and headaches.

Benefits Of Rain Gutters

By diverting water, rain gutters safeguard your home’s exterior, prevent insect and rodent infestation, and protect against mould. Some would even swear that rain gutters help circumvent damage to landscaped yards by preventing water clogging, soil erosion and diverting large quantities of water that could possibly drown sensitive plants.

How Often Should You Get Your Rain Gutters Cleaned?

At least twice a year if you intend to get away with as little of this chore as possible, and four times a year if you’re particular about such things.

Another factor determining how often you need to clean is the tree coverage around your home—if you’ve got many trees, you’ll need to clean your gutters more often. However, even without tree coverage, you should clean your gutters right after a storm to ensure they stay clean.

Can You Clean Your Rain Gutters by Yourself?

Yes. It is possible to clean rain gutters by yourself. But we wouldn’t recommend it unless you’re a professional gutter cleaning specialist! Why? Because it’s hard yakka, you need a suitable and safe ladder, all the cleaning tools required, and the expertise not to damage your gutter system while cleaning. And since we’ve repaired a lot of gutter systems after homeowners had accidents while cleaning, we urge you to be cautious.

How to Keep Your Rain Gutters Maintained?

Install Gutter Guards

Gutter guards are a good investment as they prevent debris from accumulating in your rain gutters.

Repair Leakages

When getting your gutters cleaned, request that the system be checked for leaks or other signs of damage. Fixing these during the cleaning will prevent issues from worsening.

Replace Broken Parts

If your inspection turned up some expensive replacements that you couldn’t address immediately, get them done at the earliest. It is best to replace things before the weather worsens or you could risk damaging your property.

At Gutter-Vac, we’ve got the most efficient and effective tools to clean your rain gutters. Furthermore, our team of experienced professionals understands the complexity of rain gutter systems, irrespective of what kind or how old. We work to make sure it performs well against the elements!

5 Important Gutter Maintenance Tips For the Summer Months

Ah, summer! The bright summer skies also bring the storms here in Queensland. Make sure to get your gutters checked, cleaned, and storm-ready.

Unsure of where to start? Here’s everything you need to get done:

Inspect For Mould

You can find a lot more in a gutter system than creepy crawlies. Seams, holes for supporting screws, overlapping gutter segments are all perfect places for mould. 

While the cooler months might not be conducive to mould growth, ever-increasing summer heat and stagnant water in rain gutters is the perfect growing environment.

Don’t tackle mould by yourself—a facemask isn’t going to keep you safe, and water flushing isn’t going to prevent the mould from returning. Call the experts to clean and bleach your rain gutter systems. 

Check for Nests

Before you snap on your gloves and stick your hand into a rain gutter, do a cursory check for nests—birds, spiders, rodents and wasps are just a few creatures that love to nest in rain gutters. And the last thing you want is to be bitten or stung.

Remove Debris and Clean Your Gutters

Only use the blow-flush hack if your gutters are barely dirty. Don’t know what that is? Many people find it less cringe-worthy to use a leaf blower to remove light, dry debris from their rain gutters. Then they use a garden hose to flush the gutters with plenty of water. 

While it sounds simple, it isn’t. So please remember to use quality gloves, tools, and other equipment like a ladder to ensure maximum safety. Stay away from electricals if you’re using water, and call a friend, neighbour, or family member to watch over in case of an emergency.

If you find that your rain gutters are full of debris that no amount of blowing and flushing can remove, call Gutter-Vac. We’ll take care of it for you within the shortest time possible with the least inconvenience to you!

Inspect The Downspout

Downspouts are the trickier areas of rain gutter systems, and they tend to get clogged just like kitchen or bathroom plumbing—no amount of flushing will help. You need a professional. 

Call Gutter-Vac for an appointment today—we do a thorough inspection of your gutters, roof, and downspout. And should we spot an issue, our team is more than capable of handling these, so you don’t have to call in a professional repair service.

Install New Gutters (Or Replace Old Parts)

Do you have an old gutter system that’s been troubling you? Or would you like to explore seamless gutter systems to prevent mould? Happy with your current set-up but need an add on? How about gutter guards to keep debris and rodents out of your rain gutters? 

Whether it is a simple gutter cleaning service or a complex, full-scale replacement of your gutters, Gutter-Vac covers it all.

6 Signs Your Gutters Need to Be Cleaned Professionally

It is easy to forget about regular gutter maintenance.

But, did you know clogged gutters could lead to property damage as well as health risks for your family?

It is important to clean your gutters regularly. If you’re wondering when it might be time for a clean, take note of the warning signs that we look out for:

  1. Slippery Surfaces Around the House

When your gutters are clogged, they will slow down the water from flowing down the drain. Often the water starts to pool in the gutters and overflows over the sides. This results in water pools near the exterior of your house.

Fixing this can be an absolute nightmare without the right experience and training – and is a pretty late-stage issue. If you see these puddles, call a professional right away.

  1. Pests Near the Roof

A clogged gutter is a cozy place for little critters to take up residence. Clogged gutters can accumulate a lot of filth which then attracts pests and birds who feed on them.

However, pests big or small can be dangerous – many are carriers of serious diseases and parasites. That is why the job is best left to a trained professional.

  1. Leakages, Mildew, and Staining

Have you found stains or mildew around the outer walls of your house? It might mean a leaking gutter. Water is either leaking from your gutter or overflowing from a clogged gutter. Either way, your gutter needs to be cleaned and repaired.

Mildew and leakages can be dangerous to work around if you don’t take the right precautions – so make sure to hire someone who knows what they’re doing.

  1. Sagging, Pulling, or Detached Gutters

Other signs of clogged gutters are pulling, sagging, or detached gutters – in these cases, you’ll want to get them cleaned, or even replaced if necessary.

Before your gutter gets damaged further and hurts someone in the process, get your gutters checked out by a professional.

  1. Accumulating Debris

During certain months of the year, you might find a bunch of damp leaves, dirt, and bits of foliage stuck around your gutters – this serves as prime real estate for harmful microorganisms and is the tell-tale sign of a compromised gutter.

While you may be able to get the surface level debris out of the way, the gunk buildup within requires a pro cleaner’s skills to get the job done.

  1. Overgrowth in the Gutter

It is quite easy for plants to grow where water and dirt are present. Growing plants in your backyard might be your hobby, but growing them in your gutter isn’t. Plants in the gutter are a sign your gutters are unclean and clogged. 

Get them cleaned before they grow through the pipes or walls, causing lasting structural damage to your home.

Not sure when you last cleaned your gutters? That is also another sign that it’s time to call in a professional. It is not safe to clean a clogged gutter by yourself. Prevent any mishaps and call our professional team.

At Gutter-Vac, we have been offering the best gutter cleaning services for the last 20 years! Our service comes with a guarantee of quality, safety, and affordability.

5 Common Problems Caused by Clogged Gutters

Clogged gutters can prevent your roof water from draining. Once the water starts to accumulate in your gutter, it soon becomes a breeding spot for all kinds of pests and plants – both of which pose risks to your home structure and wellbeing.

That is why it is important to hire a professional to deal with a clogged gutter on time. If you wait too long, you could be up against any of these 5 serious issues:

  1. Drainage and Leakage Issues

The first problem arising from a clogged gutter is drainage. It starts slowing down at first and soon stops flowing at all. After this, the water that doesn’t get drained will start leaking or overflowing from the gutters.

Left as it is, the leaking water seeps into the doors, windows, and patio of your house. If you’ve got a beautiful flower bed around the house, then it might be at serious risk.

  1. Insect Infestations

Insect infestations aren’t easy to miss. The clogged water starts to collect debris, which starts to rot. This rot attracts insects, but by this time you’re probably aware of the source of the smell! 

  1. Broken or Corroding Gutters

Clogged gutters start accumulating dirt that soon becomes too much for the pipes to hold. This results in your gutters breaking out of their frames. Often the gutters pull down a part of the structure they’re built along – causing potentially costly damage.

If the gutters do manage to stay in place, they may still corrode, spread rust stains and cause water damage to the rest of your building structure.

  1. Foundation Damage

The dirt that gets collected along a clogged gutter, if not cleaned on time, can start to rot. The rotting substances and water keep flowing over the outer walls and enter through any cracks they can find.

Overflowing or stagnant water can also damage the edges of the roof. A damaged roof is just another entryway for water to get into the foundation of your house. The water first damages the fascia boards and then continues to weaken the ceiling of your house.

  1. Wetness and Dampness 

Where does water from your foundation accumulate, if not properly drained away? Inside the property!

If you haven’t waterproofed your nearby room, then there’s little you can do once the water starts flowing. 

There are lots of ways in which a clogged gutter can cause damage to your house, but only one way to fix it. By making sure they are cleaned regularly. Twice a year is a good number to start. Regularly check your gutters for signs of clogging or damage. Overall, the clogged gutters can lead to expensive and time-consuming repairs. Avoid both of these issues by dealing with clogged gutters today!

Note: our professional repair serviceman could also perform an inspection of your gutters and repair leaking parts or fittings.

Tips For Making Gutter Cleaning As Simple As Possible

Gutter cleaning doesn’t have to be a messy chore that leaves you physically and mentally exhausted. By preparing beforehand, you can avoid most of the unpleasantness that comes with the job. 

Organisation Tips to Remember

Here’s a list to help keep you organised with suggestions on how to simplify gutter cleaning:

  • Wear the proper attire – gloves, full sleeves work shirt, pants, and rubber-soled boots 
  • Toss the bucket and lay a tarp on your lawn. By scooping the gunk onto the tarp, you’ll protect your lawn and save yourself trips up and down the ladder.
  • Use a ladder with a stabiliser. Hook necessities like a garden hose (attached to a water source, of course) to your ladder to reduce trips up and down the ladder.
  • Use a plastic gunk scooper (a rubber spatula will work if you’re in a pinch). Don’t use metal as it might damage your gutters.
  • Keep repair supplies (drill, nails, brackets) handy and save yourself a second trip by fixing while you clean.
  • Flush your gutters once you are done cleaning out the dry leaves and debris. Don’t forget to run the water down the downspout at full pressure to ensure they’re free of blockages.

Safety Tips to Remember

Gutter cleaning can be challenging. Follow these tips to stay safe:

  • Ensure the ladder is on stable ground or is tethered to something
  • Get the correct ladder height for your house, inspect it for wear and tear, don’t overreach, and remember to check the ladder’s maximum load capacity 
  • If your home has multiple stories, get a safety harness and a spotter
  • Be careful of electrical wiring around gutters, especially if you’re using water
  • Don’t wear loose clothes that will snag on the ladder or roof
  • Wear protective gear to avoid contact with rodents, birds, mould and anything else hidden in the gunk

Reduce your workload by following these suggestions:

  • Trim tree branches and remove the main source of debris in your rain gutters
  • Get a gutter protection system
  • Schedule twice-a-year cleaning to prevent damage to your gutter system and your home

Common Causes of Gutter Leaks and How to Avoid Them

A leaky gutter poses a big problem – it can do damage to your roof, fascia, siding, and can even cause serious damage to your foundation. It can also cause garden erosion, flooding, and wood rot.

Major repairs caused by a dripping gutter can result in costly repairs and stress. Your best weapon? Prevention. Save a ton of money by knowing the common causes of gutter leaks and how to avoid them.

Cause # 1: Unsecured Gutters

When there is a leak in your gutter, one potential cause is loose or unsecured hangers. Gutter hangers are internal or external accessories or joints. These hangers make sure your gutters are securely attached to your roof’s fascia board.

Sometimes the weight of rainwater, or wet stuff stuck along the rain gutter, causes the hangers to sag. As a result, when it rains, the water will seep through the loose joints— and you guessed it right, your entire gutter system will leak.

How To Avoid This Problem: 

Your gutter should be free of debris at all times. You can hire a cleaning service to clean the wet rubbish like leaves along your gutter and maintain its cleanliness. Additionally, secure the hangers tightly to the fascia board.

Cause #2: Harsh Weather Conditions

Most of the time, your enemy is harsh weather conditions, especially when the weather changes are severe. This natural occurrence can prove worse to galvanized steel gutters. When your gutters are exposed to bad changes in weather, they tend to crack at the seams. Your gutter nails and braces can also break and crack. 

How To Avoid This Problem

The only solution is to repaint your gutters. Why? You are countering the accumulation of rust under the paint coat. It is advisable to repaint your gutters properly so they can hold up for many years. If not, you will find yourself repainting several times a year.

Cause #3: Clogs

Clogs or congested gutters are common causes of leaks. When your gutters are packed with debris, like leaf litter, water will not go out through the downspout. Instead, with all the rubbish, the water will spill out over the edges of the gutter, and over the sides. Sometimes it’s the downspout that is clogged.

How To Avoid This Problem

Regularly check your gutters for debris and simply remove them by hand. If your home is particularly situated near trees and foliage, you may want to check your gutters every two to three months. If your home is nowhere near trees, best to check annually.

Cause #4: Improper Slope

It’s all about the angle. Your rain gutters should be slightly sloped downwards. Why? So that rainwater will slide to the downspout, all the way out to the ground. If installed incorrectly, and your gutters are improperly sloped, water gets stuck along the gutters. Heavy pools of water will cause your gutters to sag— and, yes, leak.

How To Avoid This Problem

To prevent this, observe your newly installed gutters when it rains. Or hire a rain gutter technician to inspect the downward slope, and if needed, to adjust it accordingly. 

Cause #5: Cracks, Holes, and Gaps

Holes, gaps and cracks are caused by rust. How does rust develop? When rain gutters— particularly metal ones— are not maintained properly. When neglected, rainwater or debris will pool in specific areas along the gutter, which builds rust. When rust-induced holes appear,  it will certainly cause major dampness to your home. 

How To Avoid This Problem

When you spot holes, gaps, and cracks, immediately work on covering them with a silicone waterproof sealant. Or you can remove the old sealant and replace it with a new one.
