What Gutters Cost in Kent, WA
Per-foot ranges by size and material, what moves a quote up or down, and how to read two bids side by side.
The Table
In Kent, new seamless aluminum gutters run about $6 to $13 per linear foot installed for 5-inch, $8 to $15 for 6-inch; a whole house with 150 to 200 feet lands around $1,500 to $4,000. Steel costs more, copper several times more, and guards add $7 to $35 per foot.
| Item | Planning range* | Notes |
|---|---|---|
| 5-inch seamless aluminum, K-style | $6 – $13 per ft installed | The standard for most single-story roofs |
| 6-inch seamless aluminum, K-style | $8 – $15 per ft | Steep, large, or long-run roofs; pairs with 3x4 downspouts |
| Galvanized or painted steel | $9 – $25 per ft | Heavier; rusts once the coating wears through |
| Copper | $24 – $50 per ft | Fifty-year material at several times the aluminum price |
| Gutter guards, installed | $7 – $35 per ft (screens $1 – $4) | Micro-mesh for fir needles; see guards |
| Downspout replacement | about $30 – $75 each, plus labor | 2x3 or 3x4; extensions extra |
| Common repairs | $150 – $500 per item | Seams, re-hang, re-pitch; see repair |
| Whole-house replacement, aluminum | $1,500 – $4,000 | 150–200 ft of eave; fascia work extra |
*Ranges combine published figures from a Kent gutter contractor, two national gutter companies with Puget Sound branches, and 2026 national cost guides. They are planning numbers. Sales tax in Kent is about 10.1 percent and applies to the whole job.
Put together, a typical quote for a one-story Kent house with 160 feet of eave, four corners, and four downspouts in 5-inch aluminum reads somewhere around $1,600 to $2,400 before tax. Add a second story, two more downspouts, and a length of fascia and the same house is $3,000 or more.
What Moves the Number
Linear feet and corners
Gutters are priced by the foot, and every inside or outside corner is a mitered, sealed joint that takes time. A simple rectangle with four corners is the cheap case; a roofline with dormers, bump-outs, and a wrap-around porch can have twelve.
Stories and pitch
Second-story eaves mean taller ladders or staging and slower work. Steep roofs push the sizing toward six-inch, which adds a dollar or two a foot.
Fascia and drip edge
Rotten fascia found at tear-off is the most common addition to a Kent quote. A few boards run a few hundred dollars; a whole side is more. Ask for it as a unit price up front so the change order is arithmetic rather than a negotiation.
Downspout count and where they go
Each downspout is material plus elbows, straps, and an outlet. Extending them away from the foundation or into a dispersion trench adds to the job and is the part most worth paying for on a valley lot. See downspouts and drainage.
Material and gauge
.032 aluminum costs slightly more than .027 and holds up better under ladders and debris. Steel and copper are step changes in price, and copper is a choice about the look of the house as much as its lifespan.
Removal and disposal
Some contractors include tear-off in the per-foot rate; others add a dollar or two a foot. Compare bids with it in both.
Reading Two Bids
- Both should state gutter size, material, gauge, hanger type and spacing, and downspout size and count.
- Both should say what happens if fascia is rotten: a unit price per board rather than "to be determined."
- Both should say where each downspout discharges. A bid that ends downspouts at the foundation is incomplete on a Kent lot.
- Check the contractor's L&I registration on the state's verify site. Gutters are a specialty contractor category in Washington with a $15,000 bond, and the search takes a minute.
- A bid a third lower than the other usually left something out; find out what before choosing it.
