When Should You Replace Your Eavestrough? The Repair Most Homeowners Put Off
There’s a drip at the corner. Maybe a dark streak under the gutter. You make a note to look at it next weekend.
Then another season passes. Eavestrough problems are easy to put off because they often start small and happen above eye level. New U.S. renovation research puts a number on how seldom homeowners tackle the work. For West GTA homeowners, the more useful question is simple: when can an eavestrough be repaired, and when is replacement worth pricing out?
What recent homeowner research found
Two 2026 U.S. reports looked at different groups of homeowners. They provide useful context, but neither tells us how many Mississauga homes need new eavestroughs.
of U.S. homeowners surveyed reported gutter work in the previous year.
Great Day Improvements, 2027 report (published October 2026)
of U.S. homeowners in Houzz’s outdoor-renovation group upgraded gutters or downspouts.
These figures describe different groups. Great Day Improvements surveyed 2,826 U.S. homeowners, while Houzz surveyed 1,191 U.S. users involved in outdoor renovations. Different groups and questions mean the percentages should not be compared as a before-and-after change. An owner who didn’t replace gutters last year may simply have gutters that are working fine.
Houzz also reported that 71% of the homeowners in its outdoor-renovation study hired a professional. For anyone already arranging roofing, fascia or soffit work, it makes sense to check the eavestrough at the same time. Access is already being planned, and the adjoining materials can be inspected together.
Why eavestrough work tends to wait
A leaking faucet gets noticed right away. A leaking gutter corner can drip onto a patch of soil for years. From the ground, you might see the stain but not the joint that caused it.
There’s also the uncertainty of the bill. Is it one corner that needs resealing? A downspout that needs moving? Or a full replacement with fascia repairs? Until someone checks, the cost is hard to judge.
That’s a good reason to ask for a clear estimate before deciding whether an older gutter needs replacing.
What happens when a failing eavestrough is left alone?
Not every drip leads to major damage. But repeated roof runoff in the wrong place can create other repairs.
- Fascia: water behind a gutter can repeatedly wet the supporting wood. If the board deteriorates, it may need replacement before a new gutter can be securely installed. See our fascia repair and capping service.
- Soffit and siding: overflow can leave streaks and staining. Persistent moisture calls for a check of the gutter, flashing and wall details rather than cleaning the stain alone.
- Foundation and landscaping: short or disconnected downspouts can discharge where water collects near the house. Mississauga advises directing roof downspouts two metres away from the foundation and away from neighbouring properties. Read the City’s drainage guidance.
- Walkways: water sent across steps or driveways may leave slippery or icy patches when temperatures drop.
If water is coming from a roof or wall-flashing defect rather than the gutter, replacing the eavestrough alone won’t correct it. The water path needs to be checked first.
Repair or replace? Start with the condition of the system
Age by itself isn’t the deciding factor. A straight, securely fastened run with one leaking corner is a different job from gutters that sag along two elevations.
| What you see | What to consider |
|---|---|
| One corner drips; the rest is straight and sound | Inspect the joint and sealant. A targeted repair may be enough. |
| One downspout is loose, crushed or poorly directed | Repair or re-route that downspout before replacing the whole system. |
| Several sections sag, leak or pull away | Assess fascia condition, slope and whether replacement is more practical. |
| Overflow continues after debris is cleared | Check sizing, roof valleys, outlets and downspout locations. A larger system is only one possible solution. |
| Wood behind the gutter feels soft or appears rotten | Inspect and repair the fascia before fastening new eavestrough. |
For larger roof areas or heavy valley runoff, a 6-inch system may make sense. For a simpler roof, a well-installed 5-inch system with properly placed 3×3 downspouts may be enough. With 6-inch eavestrough, we assess whether 3×3 or higher-flow 3×4 downspouts suit the outlet and final drainage route. Read our 5-inch vs 6-inch eavestrough guide for the full comparison.
What matters most when choosing a contractor?
In the Great Day Improvements U.S. survey, a clear understanding of costs and return on investment ranked ahead of warranty coverage and choosing the lowest quote. The survey wasn’t conducted in Canada, but the questions it raises are worth asking here too.

What should a written eavestrough estimate include?
Start with the measured work, then check what the price covers. On a West GTA home, a useful estimate should make these items clear:
- Footage and rate: measured linear feet, the price per foot where applicable, and the total.
- Gutter and downspout details: 5-inch or 6-inch profile, downspout size, quantities, outlets and discharge locations.
- Included labour: removal and disposal, corners, hangers, end caps and sealing, as applicable to the scope.
- Separate work: fascia wood replacement, soffit, roofing, underground drainage, lift rental or any other work not included.
- Taxes, warranty and schedule: whether HST is extra, what workmanship coverage applies, and the expected timing.
Maxima Aluminum LTD publishes planning ranges of $8–$13 per linear foot for 5-inch and $13–$17 per linear foot for 6-inch seamless aluminum installation on its 2026 pricing page. Those are starting ranges, not a property-specific total. Height, corners, downspouts, removal, access and repairs affect the estimate.

One detail worth asking about: A new eavestrough cannot be made secure by fastening it to rotten fascia. If the wood needs work, that should be identified before installation, not added as an unexplained surprise later.
A five-minute check you can do from the ground
Walk around the house after the next rain. You don’t need to climb onto the roof.
- Look for overflowing water, especially at corners and below valleys.
- Check downspout outlets. Is the water reaching a safe discharge area away from the house?
- Look for streaks on fascia, soffit or siding below one spot.
- Check for sagging sections or a gutter pulling away from its backing.
- Look at the ground for fresh erosion, pooling or washed-out mulch.
- Take two photos: one close-up of the problem and one showing the whole roofline.
If everything drains well and the system is secure, there may be nothing to replace. If you see repeated overflow, loose sections or damp wood, an assessment is worth arranging.
Can gutter guards put an end to the problem?
They can reduce clogs from leaves and debris. Alu-Rex T-Rex and DoublePro are options for suitable new systems, and retrofit guards may be appropriate when existing gutters are in good condition. But guards do not correct poor slope, damaged fascia or inadequate outlets. Those problems have to be dealt with first. See our gutter guard options.
Frequently asked questions
How do I know if my eavestrough needs replacing?
Check for multiple leaks, sagging, loose fasteners, repeated overflow after cleaning, and damaged fascia. One isolated leak may be repairable. The condition of the full system determines whether replacement is worthwhile.
Is it cheaper to repair a gutter than replace it?
A small, accessible repair often costs less than full replacement. Repeated repairs across several sections can change that calculation. Ask for both options when the system is otherwise serviceable.
How much does eavestrough replacement cost in Mississauga?
Maxima’s 2026 planning ranges are $8–$13 per linear foot for a 5-inch seamless aluminum system and $13–$17 for a 6-inch system. A complete estimate must also account for downspouts, corners, access, removal and any repairs. Use the cost calculator for an initial estimate.
Should I replace fascia and gutters at the same time?
Only if the fascia needs repair or replacement. Solid fascia can often remain. If the supporting wood is rotten, it should be repaired before new eavestrough is fastened to it.
Does a 6-inch eavestrough always need 3×4 downspouts?
No. A 6-inch system may use 3×3 or 3×4 downspouts depending on roof area, outlets and the discharge connection. A 3×4 downspout is a strong choice for higher-flow locations when the drainage route can accommodate it.
What warranty comes with Maxima Aluminum’s eavestrough work?
Qualifying new installations may include Maxima Aluminum LTD’s 5-year workmanship warranty when stated in the agreement. Repairs and partial replacement work are not automatically covered. Material warranties are separate and depend on the product.
