Most KC homeowners try to repair before they replace, which is usually the right call. But sometimes the repair is throwing good money after bad. Here are 5 signs you're past repair.
Sign 1: Rust through (steel gutters)
Aluminum gutters don't rust. If you see rust spots on your gutters, you have steel — and once steel starts rusting through, you're in the last 1-3 years of service life. Patches won't last.
Time to replace. Upgrade to aluminum (lasts 30-40 yrs) or copper (75+ yrs).
Sign 2: Multiple sagging sections
One sagging gutter run usually means one failed hanger — fixable for $200-$400. But if you have multiple sags in different runs, the hanger system as a whole has failed. Often the fascia behind has rotted from years of water seepage, too.
Time to replace. Repairing 3+ sections individually costs almost as much as a new install, and the rest will fail within 1-2 years.
Sign 3: Visible fascia rot
If you can see soft, dark, or discolored wood behind the gutter (or your hand can press into it), water has been getting behind the gutter system for years. Even if the gutters look ok from the ground, they're not draining properly.
Time to replace BOTH gutters and fascia. Putting new gutters on rotted fascia means they fall off within 2-3 years.
Sign 4: Multiple miter leaks
Mitered (cornered) gutter joints are sealed with caulk. Caulk lasts 5-10 years before drying out and cracking. If you have one corner leak, recaulk it ($150-$300). If you have multiple corner leaks, the whole caulk system is at end of life.
Time to replace. Recaulking corners individually only delays the inevitable. Modern seamless installs have far fewer mitered corners (often just at outside corners of the house), reducing failure points by 60-80%.
Sign 5: Age over 25 years on aluminum, 15 on steel
Even gutters in apparent good condition reach material end-of-life. If you don't know when your gutters were installed and the home is 25+ years old, assume they're original and budget for replacement.
How to estimate age:
- Steel gutters with rust = pre-1990 install (35+ years)
- Aluminum with no fade = installed within last 10 years
- Aluminum with significant fade = 15-25 years old
- Aluminum with paint peeling = end of life regardless of age
Bonus sign: Basement water during heavy rain
If your basement gets wet during heavy storms, the gutters might not be the structural problem — but they might be exacerbating it. Even working gutters that dump water at the foundation cause basement seepage in KC clay soil. Replacement (with underground downspout extensions) often fixes basement water more cheaply than interior waterproofing.
What replacement actually costs in KC
For a typical KC ranch (140-180 lf), full replacement runs $1,600-$2,800. For a 2-story home (180-220 lf), $2,400-$4,200. Add LeafBlaster Pro guards for $1,400-$3,000. See our Pricing page for the full breakdown or use our Cost Calculator for an instant estimate.
