The thing about eavestroughs is that it’s obvious when there’s an issue. Just by looking at your system you can tell if you need an update. If your home’s gutters are leaking, sagging, covered in mold, or constantly clogging, it’s time for a repair or a full replacement.

For most Ontario homeowners, professional eavestrough replacement and installation is the smarter investment (rather than a repair). A new aluminum system prevents issues that a quick repair doesn’t. And it not only keeps rainwater away from your foundation but also improves curb appeal and gives you peace of mind.

Here’s what you need to know about when to replace, what goes into installation, and how to choose the right installer near you.

Why Most of the Time Eavestrough Replacement Is Necessary

Old or damaged eavestroughs do more harm than good (it’d almost be better to have no gutters than ones that are directing water toward expensive damage-prone areas). If you notice any of the following, it’s usually time for replacement:

• Cracks, holes, or visible rust
• Sagging sections that pull away from the fascia
• Constant leaks, especially around corners
• Overflow during moderate rain
• Peeling paint or rotting fascia boards behind the trough

Small fixes may buy you time and seem like saving you money. But the reality is that repeated repairs add up and quick fixes can cause future problems. A full eavestrough replacement gives you a long-term solution with fewer worries about hidden water damage.

Why Professional Eavestrough Installation?

It’s simple: a DIY can cause loads of damage. We can’t even tell you the number of times (more than we can even remember!) a DIY ended up in a call for us to come replace it all. A professional eavestrough installation will prevent any issues for many years (or even decades).

What to Expect with Professional Eavestrough Installation

Professional eavestrough installers do more than simply attach a trough to your roofline. A quality installation should include:

• Proper slope: Ensures water flows smoothly to downspouts without pooling.
• Secure hangers: Aluminum hangers placed at the right spacing provide strength to handle heavy rain and snow.
• Downspout placement: Strategically directs water away from your foundation, driveway, and walkways.
• Seamless aluminum runs: Cut on-site for a perfect fit with fewer weak points.

This level of detail is what separates a trusted local installer from a big box DIY kit.

The Difference in Corners: Hand-Mitred vs. Pre-Made

One of the clearest signs of professional craftsmanship is how the corners are finished. Just one quick look at your house and we can tell if it was done by an expert or not.

Many DIY jobs or budget installers use pre-made aluminum or plastic corner pieces. They go on quickly but leave bulky seams that are prone to leaks and stand out visually.

At The Eavestrough Company, we use custom hand-mitred corners. Every corner is measured, cut, and sealed on-site to fit your home. This method creates:

• A cleaner look without bulky joints
• Better performance thanks to proper sealing and slope
• Longer lifespan with fewer seams that can fail

Corners are the most vulnerable point of any eavestrough system. Choosing an installer who uses hand-mitred corners makes all the difference in durability and appearance.

Why Aluminum Seamless Eavestroughs Are the Best Choice

When it comes to new eavestroughs, the material and installation method matter just as much as the size.

Aluminum strength and durability

Aluminum is lightweight, rust-resistant, and built to handle Ontario’s harsh winters. Unlike vinyl, which can crack, or steel, which can rust, aluminum strikes the perfect balance of performance and value.

Canadian-sourced products

At The Eavestrough Company, we use Canadian aluminum from trusted suppliers like Gentek, Kaycan, and Royal Building Solutions (each backed by a 25-year manufacturer’s warranty!). These companies are based in Ontario and Quebec, so you’re supporting Canadian through and through.

Seamless custom fit

Sectional systems sold at big box stores should be avoided, unless it’s for a small project like a shed. Anything larger (like your home), use seamless aluminum eavestroughs that are cut on-site to the exact length of each run. This eliminates the need for bulky connectors every few feet (and also looks much better – adding to curb appeal and value).

Fewer seams, fewer leaks

Because seamless systems are continuous, there are fewer weak points where leaks can develop. The result is both a cleaner appearance and a system that performs better over time.

In general, seamless aluminum eavestrough installation is considered the industry standard for long-lasting protection and curb appeal. See our seamless eavestroughs in action here.

Choosing the Right Eavestrough for Your Home

5” vs 6” eavestroughs

Most Ontario homes use standard 5” eavestroughs, but larger or more complex rooflines may need 6”. A bigger profile handles more water during heavy rain. (For a deeper comparison, see our blog: 5 vs 6 Inch Eavestroughs)

Seamless aluminum for durability

Seamless aluminum is the gold standard for eavestrough installation near me. It’s lightweight, rust-resistant, and cut to your home’s exact dimensions. (Read more about our gutter services: Eavestrough Replacement and Protection)

Eavestrough protection with Alu-Rex

Adding gutter protection/leaf filters is a strong recommendation, especially if you have trees nearby.

It’s a small upgrade that does wonders to extend the life of your system (and reduce eavestrough maintenance).

Eavestrough Installation Cost Factors in Ontario

Wondering about eavestrough installation cost? Prices vary depending on:

• Total length of runs
• Number of corners and stories on your home
• Condition of fascia and soffit
• Add-ons like Alu-Rex protection

While DIY might look cheaper on paper, poor slope or sealing often leads to water damage that costs far more to fix. A professional installation is an investment in your home’s protection.

Finding The Right Eavestrough Installers Near You

Unfortunately, not all companies are equal. You will get drastically difference value, quality, and workmanship across different companies. When searching for an eavestrough company, ask:

• Do they use hand-mitred corners instead of pre-made?
• Do they work with aluminum from trusted Canadian suppliers?
• Do they offer a workmanship guarantee?
• Are they locally-owned and familiar with Ontario’s heavy rainfall and freeze-thaw cycles?
• Do they have examples of their work – photos and reviews from real clients?
