Signs you need new gutters (and what replacement costs)
Some gutter problems are a $60 fix; others mean the whole run is done. Here is how to tell repair from replace, and what each costs.
Gutters do not usually fail all at once. They give warning signs. Catching the difference between a repair and a replacement saves money in both directions — patching a dead gutter wastes cash, and replacing a fixable one wastes more.
Signs it is time to replace
- Cracks and splits along multiple sections — small ones spread; widespread cracking means the material is done.
- Sagging or pulling away from the fascia across whole runs — the metal has fatigued or the fascia behind it has rotted.
- Rust and holes in steel gutters — once it is perforating, patches are a losing game.
- Peeling exterior paint or stains on the siding below — chronic overflow that a cleaning did not fix.
- Pooling water or eroded soil at the foundation — the system is not moving water away.
- Many leaking joints at once on sectional gutter — resealing every seam repeatedly is a signal to go seamless.
- Mildew or basement moisture traced to roof runoff at the wall.
Signs it is just a repair
A single sagging span (rehang it), one leaking joint (reseal it), a detached downspout (refasten it), or a bent section from a ladder or branch — these are spot fixes. Repair cost = (sum of the repair items − discount) × (1 + contingency). Example: reseal 5 joints at $15 + rehang 20 feet at $4 + fix one downspout at $60 → (75 + 80 + 60) × 1.10 = $236.50. Price yours in the gutter repair cost tool. If repairs keep stacking up season after season, that recurring spend is telling you to replace.
What replacement costs
Replacement is remove-plus-new: (linear feet × removal $/ft + linear feet × new $/ft + downspouts + labor − discount) × (1 + contingency). Example: (110 × $1 removal + 110 × $8 new + $135 downspouts + $400 labor) × 1.10 = (110 + 880 + 135 + 400) × 1.10 = $1,677.50. Run yours in the gutter replacement cost tool; for a fresh install without removal, use installation cost.
The repair-or-replace test
A rough rule: if the fixes would run more than about half the replacement cost, or the same problems recur every year, replace. New gutters buy you a fresh material lifespan, a chance to upsize (5-inch → 6-inch if the roof outgrew them — see what size you need), go seamless, and add guards in one job.
Do not confuse gutter failure with a bigger problem
Water at the foundation can come from gutters or from grading and subsurface drainage. Gutters’ job ends at the discharge point 4–6 feet from the wall; beyond that, pooling is a foundation / yard-drainage issue for a different specialist, not a new gutter. Fix the gutters first, then see if the water problem remains.
What to measure first
Get the linear feet of gutter, the number of downspouts, and per-foot prices (removal, new, labor) from a quote. Then compare the repair total against the replacement total on your own numbers.
Bottom line: replace when cracks, sagging, rust or overflow show up across whole runs or repairs recur; repair when it is a single joint, span or downspout. Every figure is a planning estimate on your own prices — get itemized written quotes from licensed, insured contractors before you commit.
