Eavestrough Installation, Repair & Replacement in Mississauga & the West GTA
Seamless aluminum eavestrough installation, repair, and replacement in Mississauga and across the West GTA — formed on site to your exact roof lengths, sized correctly (5″ or 6″ K-style), and fastened to structure for long-term reliability. As a local Mississauga-based exterior contractor since 2002, we install, repair, and replace eavestroughs with the same crews and same standards across every neighbourhood we serve. We size the runs correctly, set proper slope, place outlets where they’ll perform, and back every install with manufacturer material warranties — 40+ year service life on premium aluminum eavestrough, soffit, fascia, and cladding, plus up to 25 years on Alu-Rex gutter guard systems. We serve Mississauga, Oakville, Burlington, Brampton, Milton, Etobicoke, North York, Vaughan, Caledon, and Georgetown — plus surrounding Halton Hills (Acton) on request.

Eavestrough Replacement in Mississauga & the West GTA
When repairs no longer hold, full eavestrough replacement is usually the better long-term value. We replace 5″ and 6″ K-style seamless aluminum eavestrough systems across Mississauga, Oakville, Burlington, Brampton, Milton, Etobicoke, North York, Vaughan, Caledon, and Georgetown.
Common signs you need eavestrough replacement: repeated seam leaks even after resealing, sagging runs pulling away from fascia, overflow after cleaning, fascia rot behind the gutter line, or a 15+ year-old system with multiple patches. For a detailed homeowner guide, see our 10 signs your eavestroughs need replacing instead of repairing.
What’s included in a full eavestrough replacement
- Removal and disposal of old eavestroughs, downspouts, and hangers
- Seamless aluminum runs rolled on-site to exact roof lengths — no lap joints within a run
- 5″ or 6″ K-style sizing based on roof area, pitch, and drainage path
- Proper slope, structural fastening, and clean corner mitres
- New 2×3″ or 3×4″ high-flow downspouts sized to roof volume
- Extensions and splash blocks to direct discharge safely away from the foundation
- Optional Alu-Rex T-Rex or DoublePro gutter guards installed during replacement
- Colour-matched finishes (Kaycan, Gentek standard colours)
A complete eavestrough replacement is typically finished in one working day. Plus we bundle replacement with soffit, fascia, and downspout work where that saves you 15–25% versus separate contracts.
When eavestrough replacement makes more sense than repair
Eavestrough replacement is the better choice when the system is 15+ years old, has multiple corner leaks, sags between hangers, overflows after cleaning, or shows fascia damage from past leaks. A clean replacement also lets us correct undersized runs. For example, upgrading a 5″ system that’s been overflowing to a 6″ K-style with 3×4″ downspouts solves the volume issue at the same time.
Advantages of expert installation
- Built to last: Correct slope and hanger layout reduce standing water, overflow and early wear.
- Leak-resistant: Tight corners and end caps, sealed with the right products for aluminum.
- Tailored layout: Outlet placement and run length matched to roof shape and drainage paths.
- Properly sized: 5″ K-style on standard bungalows and townhomes; 6″ oversize on 2-storey detached homes with complex roofs or large catchment areas.
- Clean job sites: We protect landscaping, keep debris contained, and leave your property tidy.
- Backed work: Clear timelines, itemized quotes, and manufacturer material warranties (40+ year aluminum service life, up to 25 years on Alu-Rex guards).
Eavestrough installation
Every home drains differently. That’s why we assess roof area, valleys and runoff paths before we start. Then we form seamless aluminum troughs on site to your exact lengths — no joints in the middle of a run — set consistent pitch, and anchor into framing (not just cladding) for strength.
Our installation process
- Measure roof sections and recommend the right profile and size (5″ K-style or 6″ K-style where needed).
- Form seamless aluminum lengths on site and dry-fit corners/miters for clean alignment.
- Set slope and secure with proper hangers and fasteners into structure.
- Seal joints, add 2×3″ standard or 3×4″ high-flow outlets, and test flow to each downspout.
- Walk the site with you before final cleanup so you can confirm every detail.
Eavestrough repair
Most leaks and overflows come from tired sealant, poor slope, or loose hangers. However, the visible leak is often not the root cause. Therefore, we track the issue and fix it so water goes to the downspouts — not behind the fascia. For quick homeowner checks, see our guide to eavestrough & gutter repairs.
Common fixes we handle
- Reseal miters, end caps and outlet seams.
- Re-slope sections and add hangers to stop pooling and sag.
- Replace crushed or warped lengths; upgrade undersized outlets.
- Add Alu-Rex leaf protection to reduce debris and maintenance.
Roughly 40% of repair calls we receive across Mississauga and the West GTA turn into smaller targeted fixes; the rest are homes where a full replacement is the better value — and we’ll always quote both so you can decide.
Maintenance that actually helps
Seasonal cleaning plus a quick tune-up (slope, hangers, outlets) keeps gutters moving. In addition, after heavy leaf drop or spring thaw, a short service visit now can prevent bigger repairs later. In mature-tree neighbourhoods like Lorne Park, Erindale, Erin Mills, and Bayview Village, we recommend either an annual cleaning or pairing the eavestrough with Alu-Rex T-Rex or DoublePro gutter guards to cut maintenance dramatically.
Materials we recommend
- Seamless aluminum (5″ K-style): The default choice for most West GTA single-family homes. Lightweight, corrosion-resistant, widely colour-matched, and excellent value. Handles typical Ontario rainfall load on roofs up to about 1,500 sq ft of catchment area.
- Seamless aluminum (6″ K-style oversize): The right choice for 2-storey detached homes, large or steep roofs, long single-downspout runs, or homes that have had overflow issues. Pairs naturally with 3×4″ high-flow downspouts.
- Copper: Premium longevity and curb appeal for heritage or custom homes (Lorne Park, Oakville heritage districts, executive properties).
5″ vs 6″ K-style — how we decide
5″ K-style is standard for most Mississauga, Oakville, and Brampton single-family homes — it handles typical Ontario rainfall on roofs up to roughly 1,500 sq ft of catchment area. 6″ K-style is the right choice if:
- You have a 2-storey detached home with a steep roof
- A long roof line is feeding a single downspout
- You’ve had overflow at valleys or downspout drops on the existing 5″ system
- Your home is in South Mississauga lakefront (Port Credit, Lorne Park) where wind-driven rain loads are higher
- You have large catchment areas in Erin Mills, Streetsville, or Meadowvale executive homes
Upgrading from 5″ to 6″ K-style usually adds $400–$800 on a standard Mississauga detached home, recovered in avoided damage to window wells, grading, and foundation over the system’s life.
Costs: what to expect
Pricing depends on run length, number of corners, height/access, and whether damaged sections need removal. Typical West GTA installed ranges:
| Profile | Per Linear Foot (Installed) | Typical 100–180 ft Home |
|---|---|---|
| 5″ K-style seamless aluminum | $8–$13 | $1,800–$3,200 |
| 6″ K-style oversize | $13–$17 | $2,400–$4,000 |
Bundle savings: Combine eavestrough with soffit + fascia + downspouts in one visit and save 15–25% on staging, crew time, and disposal overhead.

Frequently Asked Questions about Eavestroughs
Eavestrough Costs
How much does eavestrough installation cost in Mississauga and the West GTA?
Most West GTA single-family homes fall in the range of $8–$13 per linear foot installed for 5″ K-style or $13–$17 per linear foot for 6″ oversize K-style. A typical 100–180 ft Mississauga home runs about $1,800–$3,200 (5″) or $2,400–$4,000 (6″), depending on number of corners, height and access, and whether we’re removing old gutters. For an instant per-city ballpark, use our Eavestrough Cost Calculator — we confirm exact pricing after a site visit.
Gutter Sizing
What is the difference between 5″ and 6″ K-style eavestroughs?
Standard 5″ K-style handles most 1- and 1½-storey bungalows and townhomes in Mississauga and the West GTA without overflow issues. For 2-storey detached homes — especially ones with large roof surfaces, steep pitches, or north-facing slopes that dump snowmelt — we recommend 6″ oversize K-style with 3×4″ high-flow downspouts. Upgrading from 5″ to 6″ usually adds $400–$800 on a standard Mississauga detached home, recovered in avoided damage to window wells and grading.
Gutters and Downspouts Together
Do you replace gutters and downspouts at the same time?
In most full replacement projects, yes — we install new gutters and downspouts together so the system works as designed. That said, if existing downspouts are still in good shape, we can sometimes tie into them. On longer runs we often recommend adding a downspout drop to split the load and prevent overflow at valleys.
Gutter Guards
Can you add Alu-Rex gutter guards during installation?
Yes. Many homeowners add Alu-Rex T-Rex or DoublePro gutter guards during a new install or full replacement. As an Alu-Rex Elite Installer, we install the certified product set. Cleaning is reduced and clogs are less frequent — especially during fall leaf drop in mature-tree neighbourhoods like Lorne Park, Erindale, and Bayview Village.
Repairs vs. Replacements
Do you offer repairs, or only full replacements?
We do both. If a repair will last, we suggest and price that option first. Roughly 40% of repair calls turn into smaller targeted fixes. However, if gutters are badly warped, rotted, undersized, or 15+ years old with multiple existing patches, we’ll explain why a full replacement is better long-term value.
Financing Options
Do you offer financing for eavestrough projects?
Yes. For qualifying projects, financing options may be available so you can spread the cost over time. We can review current programs and sample monthly payments with your quote.
