Ontario puts eavestroughs through one of the harshest weather cycles in North America: spring snowmelt, summer thunderstorms, heavy autumn leaf accumulation, and repeated winter freeze-thaw cycles. A small leak at a joint today can rot the fascia board behind it, saturate basement insulation, and crack foundation walls over one or two seasons. Early eavestrough repair is almost always cheaper than the water damage it prevents.
Old sealant cracks under UV exposure and temperature swings. Dripping joints soak the fascia board and lead to wood rot directly behind the eavestrough.
Hangers loosen over years of freeze-thaw movement. A sagging eavestrough pools standing water, accelerates rust, and eventually causes full sections to detach.
A split downspout section sends water behind siding and into the wall cavity. Quick replacement stops hidden moisture damage before it spreads.
Overflow from a blocked or damaged eavestrough concentrates water at your home's base, pushing through foundation cracks into the basement.
Paint stripping along siding under the eavestrough is a sign of chronic overflow. Fix the eavestrough before repainting or the problem repeats.
Rust streaks or pinhole leaks in galvanized steel troughs mean the material has corroded through. Affected sections must be replaced, not patched.
Our trucks carry aluminum profiles, downspout components, sealant, and hanger hardware for the most common Ontario eavestrough repairs — most jobs are done in a single visit.
Remove old sealant, clean the joint surface, and apply new long-life butyl or silicone sealant to eliminate leaks at seams and corners.
Replace worn hangers with concealed-fastener brackets or drive new spikes at the correct pitch to restore proper drainage slope.
Cracked or missing end caps let water shoot sideways off the roof line. We carry matching aluminum end caps in standard Ontario colors.
Full or partial downspout replacement in matching color and profile, including elbows, bands, and underground extensions.
Fix or replace cracked outlets and elbows at the point where downspouts connect to the trough — a common source of hidden wall leaks.
When a section is too corroded or bent to repair, we cut and splice in a new matching segment sealed at both ends.
The right answer depends on the age of your system, the extent of damage, and the material. Our technicians give you an honest assessment — we never recommend replacement when repair is the smarter call.
If replacement is the better path, EavesArmour offers seamless eavestrough installation and can add micro-mesh gutter guards at the same time. See our 2026 Ontario eavestrough cost guide for full pricing detail.

Most eavestrough repairs in Ontario range from $100 to $400 depending on the type and extent of damage. Simple joint resealing starts around $100–$150, while sagging eavestrough rehang costs $150–$250 per section. Full downspout replacement typically runs $175–$300. EavesArmour provides free, no-obligation estimates so you know the exact cost before any work begins.
Repair is usually the right choice when damage is isolated — a single leaking joint, a loose hanger, or a cracked end cap. Replacement makes more sense when eavestroughs are over 20 years old, have widespread rust or corrosion, or have damage along more than 50% of their length. Our technicians inspect your system and give you an honest recommendation — we never upsell replacement when repair is the right call.
Watch for water dripping from gutter joints during rain, gutters visibly pulling away from the fascia, sagging sections, paint peeling on siding below the eavestrough line, pooling water near your foundation, or visible rust staining. Any of these signs mean a repair is needed before water finds its way into your home’s structure.
Yes. EavesArmour technicians repair aluminum, vinyl, galvanized steel, and copper eavestroughs. Aluminum is the most common material in Ontario and the one we repair most often. Our trucks carry matching profiles, downspout components, end caps, and hangers so most repairs are completed in a single visit.
Many repairs can be completed year-round, including rehanging sagging sections, replacing downspout components, and clearing blockages. Sealant applications work best above 5°C — in cold weather we may apply a temporary fix until spring allows a permanent seal. We always advise on the best approach for the conditions.
Most eavestrough problems we repair come back without the right protection in place. Add these to your project.
