Most gutter repairs on Mercer Island run between $150 and $600. A simple reseal or downspout reattachment sits at the low end. Re-pitching a full run, swapping a damaged section, or fixing the fascia board behind the gutter pushes toward the top. The exact number comes down to what failed and why, and on Mercer Island the “why” is almost always the tree canopy.

The gutter problems we fix most often on Mercer Island
Nearly every gutter repair call on the island traces back to one of six issues. Here is what each one looks like, how we fix it, and what it usually costs.
| Problem | What you notice | Typical fix | Ballpark cost |
|---|---|---|---|
| Clogged and overflowing | Water sheets over the front edge, stains down the siding | Clear the run, reseal, optional guards | $150–$300 |
| Loose or sagging gutter | Gutter pulling away from the fascia, a visible gap at the roofline | Refasten with hidden hangers, re-pitch for flow | $200–$450 |
| Leaking seams or corners | Drips at the joints, rust streaks under a seam | Reseal seams or replace the corner miter | $150–$350 |
| Damaged section | A dented, split, or bent length of gutter | Replace the section in matching seamless aluminum | $10–$20 / linear ft |
| Fascia or soffit rot | Soft wood behind the gutter, peeling paint, the gutter won’t stay up | Repair the fascia, then rehang | $300–$800 |
| Downspout problems | Disconnected, crushed, or dumping water at the foundation | Reattach, replace, or extend away from the house | $100–$300 |
Why Mercer Island gutters fail faster than most
Mercer Island is one of the most heavily treed neighborhoods in King County, and that beauty is hard on gutters. A few things work against you here:
- The tree canopy. Firs, cedars, and big-leaf maples shed needles and debris all year. That debris packs into the gutter, holds water, and adds weight that pulls fasteners loose.
- The wet season load. A Pacific Northwest winter runs water through your gutters for months. A gutter that is even slightly clogged or off-pitch overflows, and that water finds the fascia.
- Moss and granule buildup. Shaded, damp roofs shed moss and shingle grit straight into the gutter, where it turns into a heavy sludge.
- Older homes. Many island homes still run their original gutters and fascia. Decades of that cycle is usually what we find behind a sagging run.
Repair or replace? A simple way to decide
You can usually repair when the problem is localized: one run sagging, a few leaking seams, a single damaged section, and the metal everywhere else is still sound. Most gutters under 15 to 20 years old are worth repairing.
Lean toward replacement when the trouble is everywhere at once: widespread sagging, rust or corrosion along multiple runs, seams failing in several places, or gutters so old they no longer hold a clean pitch. If you are already re-roofing or repainting the trim, replacing the gutters at the same time is the smarter spend. New seamless aluminum has almost no joints to leak and is the standard we install. You can see the details on our gutter replacement page.
