Why Eavestroughs Matter in Renfrew County
Eavestroughs — the gutters that run along the edge of your roofline — do one job: collect rainwater and snowmelt from your roof and channel it away from the foundation. When they work correctly, this function is invisible. When they fail or clog, the consequences accumulate quickly and can be expensive.
Renfrew County's climate makes functional eavestroughs especially critical. Spring snowmelt in March and April can produce large volumes of water over a short period — the Ottawa Valley regularly sees significant snowpack accumulation over winter. Heavy spring melt combined with rain creates roof runoff volumes that overwhelmed or blocked eavestroughs cannot handle. The result is water running down exterior walls, pooling at the foundation, and infiltrating basements or crawl spaces.
Fall eavestrough maintenance is equally important: eavestroughs that enter winter blocked with leaves and debris are a leading cause of ice dams — a problem that causes thousands of dollars in roof and interior damage in Renfrew County homes every year.
What Blocked Eavestroughs Lead To
- Ice dams: Debris-blocked eavestroughs prevent meltwater from draining; the water backs up to the eave edge, freezes, and ice builds up. As more melt accumulates behind the ice dam, it forces its way under shingles and into the attic or walls. Ice dam damage is one of the most frequent winter insurance claims in the region.
- Foundation water infiltration: Water that overflows from clogged eavestroughs pools at the base of the foundation rather than being directed to a downspout discharge point. Over time this saturates the soil around the foundation and creates hydrostatic pressure against basement walls — a leading cause of basement leaks and foundation cracks in older Renfrew County homes.
- Fascia rot: When eavestroughs overflow at the back edge rather than the front, water runs behind the gutter and soaks the fascia board — the wooden board the eavestrough is mounted to. Rotted fascia eventually causes the gutter to pull away from the house, and the rot can spread to soffit and roof sheathing if not caught early.
- Landscape erosion: Concentrated water discharge at unmanaged overflow points washes away soil and landscaping, and can undermine walkways or patios adjacent to the house.
Types of Eavestrough Service
Cleaning
Eavestrough cleaning removes accumulated leaves, seeds, shingle grit, and other debris from the gutter channel, and flushes downspouts to confirm they drain freely. A thorough cleaning includes checking for standing water (indicates improper slope), loose hangers, joint separations, and any visible damage. Annual fall cleaning — before the ground freezes — is the most important maintenance task for eavestroughs in this climate.
Repairs
Common repairs include resealing open joints between eavestrough sections, replacing failing hangers that allow sections to sag, patching small holes or rust spots with gutter sealant, and replacing short damaged sections. Most repairs are cost-effective and extend the life of an otherwise functional system considerably.
Full Replacement
When eavestroughs have reached the end of their service life — widespread rust, extensive physical damage, or pulling away from the fascia in multiple locations — replacement is the better investment. Seamless aluminum eavestroughs are the standard replacement product: fabricated on-site in a single continuous piece matched to your roofline, with far fewer joints than sectional systems. They resist leaks and last 20–30+ years with appropriate maintenance.
Gutter Guards
Gutter guards — covers, screens, or mesh systems that reduce debris entry — vary significantly in quality and effectiveness. Screen and reverse-curve types are less expensive but allow fine debris through; micro-mesh guards are more effective and more durable. No guard eliminates cleaning entirely, but quality guards can reduce frequency meaningfully for properties with heavy tree coverage.
Downspout Extensions
Downspouts should discharge water at least 1.5–2 metres from the foundation. Many older homes have downspouts that terminate right at the foundation wall. Downspout extensions — above-ground or buried — correct this at low cost and are one of the most cost-effective investments for basement leak prevention. Extensions connecting to a buried drainage system should be inspected periodically to confirm they remain clear.

- New aluminum eavestroughs (5" or 6"): $8–$20 per linear foot installed
- Average home (approx. 150 linear feet): $1,200–$3,000 aluminum; $3,750–$6,000 copper
- Gutter guards: $10–$30 per linear foot installed

Sizing: Why 6-Inch Eavestroughs Are Recommended Here
Standard residential eavestroughs are typically available in 5-inch and 6-inch profiles. The 5-inch profile is adequate for most southern Ontario locations. In Renfrew County, where snowpack accumulation and spring melt volumes are substantially higher, the 6-inch profile is recommended — it handles a higher water volume per unit time, reducing overflow events during heavy rain and peak spring melt. Most quality contractors in the region will specify 6-inch for new installations on this basis.
Frequently Asked Questions
How often should I clean my eavestroughs?
Twice yearly — spring and fall — is the general recommendation. In Renfrew County, fall cleaning before the freeze is the most critical: blocked eavestroughs entering winter are a primary cause of ice dams. Spring cleaning clears maple keys, cottonwood fluff, and debris that accumulated over winter. Properties with heavy deciduous coverage may need more frequent service.
What causes ice dams?
Ice dams form when heat escaping from the attic melts snow on the upper roof. The water runs down toward the colder eaves and refreezes. If eavestroughs are blocked, backed-up water has nowhere to drain and forces its way under shingles. Both blocked eavestroughs and inadequate attic insulation contribute — for a complete solution, see the insulation guide.
How much does eavestrough replacement cost in Ontario?
Seamless aluminum eavestroughs typically cost $8–$20 per linear foot installed. An average home with about 150 linear feet of gutter runs $1,200–$3,000 for aluminum. Copper runs $25–$40 per linear foot. The 6-inch profile costs slightly more than 5-inch but is recommended for Renfrew County's snowmelt volumes.
Do eavestrough installers need a licence in Ontario?
No specific trade licence is required. However, eavestrough work involves ladder access at height. Verify WSIB coverage and general liability insurance (minimum $2M) before hiring any contractor — this protects you if a worker is injured on your property.
What are gutter guards and are they worth it?
Gutter guards are covers or screens that reduce debris entry. Quality varies widely — cheap screen guards often do more harm than good. Micro-mesh guards are more effective but cost $10–$30 per linear foot installed. For properties with heavy tree coverage, quality guards can reduce cleaning frequency from twice to once per year. No guard eliminates cleaning entirely.
How do I know if my eavestroughs need replacing?
Signs include: visible rust, holes, or cracks; sections pulling away from the fascia board; water overflowing during rainfall without blockage; water stains on siding below the gutter line; sagging between hangers; or fascia rot at the gutter attachment points. Fascia rot is a key indicator — it means water has been running behind the gutter for some time.
