Eavestrough Installation and Repair in Toronto GTA

Eavestrough services in Toronto in 2026 cover the full lifecycle of the residential roof-edge drainage system — new continuous seamless aluminum eavestrough installation, full perimeter replacement on aging or damaged systems, sectional repair and reseal, downspout reconfiguration with Toronto Section 7C disconnection routing, and pairing with leaf-protection retrofit. Eavestrough is the Canadian regulatory and trade term for the gutter+downspout assembly that the Ontario Building Code 9.26.18 governs as a roof drainage system — every Part 9 residential property in Toronto requires eavestrough sized for the Climate Zone 2 25-year storm intensity (3.0 inches per hour) and ice load (4 cubic feet per 10 linear feet on north-facing eaves).

2026 GTA eavestrough cost breakdown — full perimeter scope

Floor scope ($1,600-$2,400, 1,400-1,800 sqft bungalow or single-storey detached): Aluminum Industries 5-inch K-style continuous seamless aluminum eavestrough in 0.027-inch (27-gauge), white baked-enamel factory finish, 3-inch x 4-inch downspouts (2-3 downspouts standard), hidden hangers at 24 inches on-centre, basic miter joints sealed with Geocel 2300, no kick-out flashings unless previously installed, no leaf protection. Suitable for like-for-like replacement on pre-existing fascia and like-for-like roof pitch.

Standard scope ($2,400-$3,600, 1,800-2,400 sqft two-storey detached): Aluminum Industries 6-inch K-style continuous seamless in 0.032-inch (32-gauge), 24 colour-match baked-enamel options, 3-inch x 4-inch downspouts (4-6 downspouts), hidden hangers at 18 inches on-centre, Geocel Pro Flex 4500 marine-grade sealant at all miters, kick-out flashings at every roof-wall intersection per OBC 9.27.4, ice-and-water shield underlayment extension at eave per OBC 9.26.13.4, downspout extensions terminating 4-6 feet from foundation.

Premium scope ($3,600-$5,800, 2,400+ sqft or heritage HCD properties): Aluminum Industries 6-inch K-style or half-round profile in 0.040-inch heavy-gauge aluminum, Lindab galvanized half-round for heritage Cabbagetown/Yorkville HCD properties, or copper continuous half-round for luxury Lawrence Park/Forest Hill estates, hidden hangers at 12 inches on-centre with stainless screws, Alu-Rex Gutter Clean integrated leaf protection at install, oversized downspouts (4-inch x 5-inch on three-storey or steep-pitch installs), Toronto Section 7C downspout disconnection routing to dry well or sub-grade drain (up to $1,750 rebate).

Eavestrough installation process — what RenoHouse delivers

Step 1 — In-home measurement. Roof slope and square footage assessment, fascia condition probe, existing downspout count and termination paths, dry-well or sub-grade drain candidacy assessment for Toronto Section 7C subsidy, ice-and-water shield underlayment scope decision.

Step 2 — Material selection. Aluminum Industries continuous-form portable machine delivers gutter to property in 24 baked-enamel colour matches. Heritage HCD scopes get Lindab galvanized steel half-round. Luxury scopes get copper.

Step 3 — Fascia and drip-edge prep. Fascia inspected for rot — any sister-board repair done before eavestrough install ($35-$80/linear foot). Drip-edge metal lapped under shingle starter course (most pre-1990 Toronto installs are missing drip-edge — retrofit adds $7-$12/linear foot to scope).

Step 4 — On-site continuous-run forming. Aluminum Industries portable machine produces continuous lengths matched to each run on-site, eliminating mid-span seams.

Step 5 — Hanger and eavestrough install. Hidden hangers screwed through fascia into rafter tail with 1-1/2-inch coated stainless screws at 18-inch on-centre maximum. Slope checked every 10 feet — OBC 9.26.18 minimum 1:48, target 1:30 on long runs.

Step 6 — Downspout install. Downspouts attached to outlets with sealant and stainless screws, routed down exterior wall with brackets at 6-foot intervals, terminated 4-6 feet from foundation with splash block, extension, or Section 7C sub-grade drain tie-in.

Step 7 — Kick-out flashings. Installed at every roof-wall intersection (mandatory per OBC 9.27.4). Single most common Toronto siding-rot trigger on pre-2010 stock.

Step 8 — Ice-and-water shield underlayment. Extension at eave 600mm past exterior wall per OBC 9.26.13.4. Critical on north-facing eaves where ice damming forms.

Step 9 — Final water test. Garden-hose pour at high end of every run, ponding sections re-pitched, downspout flow verified to 4-6 feet from foundation.

Eavestrough brand and profile comparison

Aluminum Industries (Canadian-made, Ontario plant) is the Toronto go-to for 85-90% of residential — continuous on-site forming, 24-colour baked-enamel match, OBC and CSA spec for residential eavestrough. Alu-Rex with integrated Gutter Clean is the leaf-protection-included premium. Lindab and copper reserved for heritage and luxury.

GTA neighbourhood considerations

Toronto core (Cabbagetown, Riverdale, Leslieville, Annex, Yorkville): Pre-1940 stock with original galvanized half-round eavestrough at end-of-service-life. Heritage Permit on HCD streets requires period-appropriate replacement — Lindab galvanized half-round or matched Aluminum Industries baked-enamel custom-colour to match heritage trim profile. Permit lead time 4-6 weeks. Premium scope mandatory.

Etobicoke (Long Branch, Mimico, Sunnylea, The Kingsway): 1950s-1970s detached bungalows with mature 50-70 year tree canopy. Annual leaf-load and helicopter-seed load is the dominant scope driver — recommend 6-inch K-style with Alu-Rex Gutter Clean integration. Foundation drainage concerns: pre-1970 clay-tile weeping-tile failures correlate with downspout disconnect scope (Section 7C subsidy).

Mississauga (Streetsville, Erin Mills, Port Credit, Lorne Park, Meadowvale): 1980s-2000s detached two-storey. Standard 5-inch builder-grade eavestrough is routinely undersized — upgrade to 6-inch K-style standard scope. Port Credit lakefront stock requires stainless hanger upgrade.

Vaughan / Maple / Woodbridge: 1990s-2010s detached two-storey with 9:12+ roof pitches. 6-inch K-style or 6-inch half-round oversized capacity standard. Italian-Canadian custom colour match to fascia in terracotta, deep brown, or charcoal — Aluminum Industries 24-colour palette.

Markham (Unionville, Cathedraltown, Berczy, Cornell): 2000s-2010s detached two-storey. Mature 25-35 year tree canopy. Alu-Rex Gutter Clean integration high-demand. Cathedraltown design-review committee for visible exterior changes.

Richmond Hill (Bayview Hill, Oak Ridges, Mill Pond): 1990s-2010s detached and estate. Premium scope mandatory on luxury estates — copper or Lindab heritage profiles common.

Oakville / Burlington (lakefront, Bronte): Salt-air and high-wind exposure. Hidden hanger spacing tightened to 12 inches on-centre per CSA A93. Stainless-steel hanger mandatory. 6-inch minimum.

Scarborough (Birchcliff, Cliffside, Guildwood): Lakefront with high-wind exposure. Hanger pull-out common — Spectra hidden hanger system 18 inches on-centre upgrade.

FAQ

What's the difference between eavestrough and gutter?

Same thing — eavestrough is the Canadian regulatory and trade term; gutter is the common US/British term. Both refer to the roof-edge drainage channel.

How long does an eavestrough system last?

Aluminum Industries 0.032-inch aluminum: 30-40 years. Galvanized steel: 20-25 years. Copper: 50-100 years. The dominant failure mode is hanger pull-out or miter-joint seal breakdown rather than the eavestrough itself.

When should I replace vs repair?

Repair makes sense if scope is under 60% of full-replacement cost on the same property. Indicators for full replacement: multiple sections with sag, miter-joint failures across multiple corners, fascia rot on more than one run, original 5-inch undersized for current roof storm intensity.

What size eavestrough — 5-inch or 6-inch?

5-inch K-style is minimum for single-storey small roofs. 6-inch K-style is RenoHouse standard for any two-storey GTA detached and any roof with pitch over 6:12 — 35% more water volume per linear foot.

Should I do leaf protection at the same time?

Yes if you have mature trees within 30 feet. Alu-Rex Gutter Clean integrated at install is $5-$8/linear foot vs $14-$22/linear foot retrofit.

Do you handle downspout disconnection?

Yes — Toronto Section 7C subsidy up to $1,750/property. We coordinate City inspection and rebate paperwork on every disconnection project.

What about ice damming?

Eavestrough scope includes ice-and-water shield underlayment extension at eave per OBC 9.26.13.4 (600mm past exterior wall). Ice damming is primarily an attic insulation and ventilation problem — we recommend pairing eavestrough replacement with attic ventilation audit.

Can you match my fascia or trim colour?

Aluminum Industries 24-colour baked-enamel palette plus custom-colour-match service. Standard turnaround 5-7 business days for custom.

Do you replace fascia at the same time?

Sister-board fascia repair under failed eavestrough adds $35-$80/linear foot. Full fascia replacement is a separate scope coordinated with eavestrough install.

What about kick-out flashings?

Mandatory per OBC 9.27.4. Retrofit add-on $120-$240 per intersection on existing roofs without them. Single most common Toronto siding-rot trigger when missing.

What warranty do you provide?

Aluminum Industries: 10-30 year finish warranty. Alu-Rex Gutter Clean: 25-year transferable. RenoHouse workmanship: 10-15 years on install. Manufacturer warranty pass-through on all materials.

Are you licensed and insured?

WSIB clearance, $2M general liability, $1M property damage on every Toronto residential eavestrough install. License copies available pre-install.
