The hardest call on a gutter system is whether to keep patching or commit to replacement. Replacement isn’t cheap (typical Snohomish County home runs $2,000 to $5,000 for seamless aluminum installed). Repair is much cheaper but only works if the underlying system has life left.
Here’s the decision tree we use.
The 5-Question Test
Answer each question honestly.
1. How old is the existing gutter system?
- 0 to 10 years: Almost always repair.
- 10 to 18 years: Repair if isolated issues, evaluate if multiple issues.
- 18+ years: Lean toward replacement.
Aluminum seamless gutters typically last 20 to 30 years in PNW conditions. Steel gutters last 15 to 25. Original sectional gutters from the 1970s-80s are well past replacement.
2. Is the existing system seamless or sectional?
- Seamless aluminum: Repair-friendly. Sections don’t leak at joints (because there are no joints between drops). Worth maintaining.
- Sectional aluminum or steel: Each joint is a potential leak. As the system ages, joints fail one after another. Repair becomes whack-a-mole.
If your home has sectional gutters and is in the 15+ year range, a full seamless replacement usually delivers better value than ongoing patches.
3. How many problem spots are there?
- 1 to 2 isolated issues: Repair.
- 3 to 5 issues: Evaluate. May still be repair if all are in the same wing.
- 6+ issues across multiple wings: Replace.
A failing system shows symptoms in multiple locations because the underlying causes (hanger fatigue, fascia degradation, joint failures) are systemic, not local.
4. Is the fascia rotted?
If yes, you need fascia repair regardless. Once you’re committing to fascia work, the cost differential between repair-and-rehang vs full replacement narrows significantly.
Common scenario: a homeowner asks for a gutter repair, we find rotted fascia, and the all-in cost (fascia repair + repair gutter + new hangers) is within 15% of a full seamless replacement. At that point, replacement gives you 25 more years of system life vs rehanging old gutters that will fail again in 5 years.
5. Are the downspouts adequate?
- 2-inch downspouts on a single-story home: usually OK.
- 2-inch downspouts on a two-story home with steep roofs: undersized. PNW rain volume regularly overwhelms 2-inch drops. Replacing with 3-inch downspouts is its own meaningful upgrade.
- Downspouts are corroded, detached, or missing extensions to grade: replacement is part of any decent rebuild.
If the downspout system is also at end of life, full replacement is usually the right answer.
When Repair Is the Honest Answer
Common scenarios where repair is correct:
- Single failed hanger or section. $200-$500 fix.
- Localized fascia rot at one corner. $400-$1,200 fix including the gutter rehang.
- One pulled or cracked downspout. $150-$400.
- Cleaning + minor sealant repair on a young system. $300-$700.
- Damage from a fallen branch on an otherwise good system. Insurance often covers; repair is straightforward.
If your situation matches any of these, replacement is overkill.
When Replacement Is the Honest Answer
Common scenarios where replacement is correct:
- 18+ year old gutters with multiple symptoms.
- Sectional gutters with leaks at multiple joints.
- Fascia rot in multiple locations indicating systemic moisture damage.
- Hanger failure on more than 30% of the runs.
- You’ve already had 2 or more repair visits in 3 years.
- You’re replacing the roof anyway (replacement gutters can be installed concurrently and get fresh underlayment kick-out flashing details).
A new seamless aluminum system at $9-$16 per linear foot installed gives you 25-30 years of low-maintenance service. The payback vs ongoing patches is usually 5-8 years.
Material Choices When You Replace
If you’re replacing, the common options:
Aluminum (most common)
- Pros: Lightweight, won’t rust, paintable, 20-30 year lifespan, good cost.
- Cons: Dents easily under impact (falling branches).
- Best for: Most PNW homes. Default choice.
Steel (galvanized or painted)
- Pros: Stronger than aluminum, holds shape under heavy debris loads.
- Cons: Will eventually rust at fastener points. Heavier (more demanding on fascia).
- Best for: High-debris properties or homes with mature trees that drop large branches.
Copper
- Pros: Premium aesthetic, develops patina, lifetime durability.
- Cons: Cost (3x to 5x aluminum).
- Best for: Architectural homes where the gutter is part of the visual character.
For most Snohomish County homes, seamless aluminum in a color that matches the trim is the right call. Avoid the urge to upgrade to steel unless you have a specific debris-load reason.
Getting an Honest Estimate
When you ask for a gutter estimate, a real contractor should:
- Walk every run of the gutter system.
- Inspect the fascia behind the gutter.
- Check downspout sizing and routing.
- Provide a written scope listing what’s being repaired vs replaced and why.
- Quote labor and material separately, not as a lump sum.
If a contractor quotes a replacement without inspecting the fascia, they don’t know what they’re quoting.
Pricing Reality (Snohomish County)
| Job | Typical price |
|---|---|
| Single hanger repair | $200 to $400 |
| Section rehang with new hangers | $400 to $1,200 |
| Fascia repair + gutter rehang | $800 to $2,500 |
| Single downspout replacement | $150 to $400 |
| Seamless aluminum gutter, full replacement | $9 to $16 per linear foot |
| Add gutter guards (premium) | $8 to $18 per linear foot |
| Steel gutter replacement | $14 to $22 per linear foot |
| Copper gutter, full custom | $35+ per linear foot |
For a typical 200-foot Snohomish County home, full seamless aluminum replacement runs $1,800 to $3,200 installed. Add guards for another $1,600 to $3,600.
