How much does 200 feet of gutters cost to install in the Seattle area?
Short answer
In the Puget Sound region, installing 200 linear feet of standard seamless aluminum gutters typically costs between $1,800 and $3,600. Prices rise if your project involves two stories, steep rooflines, hidden fascia rot repairs, or premium materials like heavy-gauge steel or copper.
Material choices and regional standards
For nearly all homes in western Washington, seamless aluminum is the gold standard. Continuous gutters are extruded directly on site to the exact length of your roofline, eliminating leak points along the run. Standard 0.027-inch or 0.032-inch aluminum costs roughly $9 to $18 per linear foot installed, including downspouts and basic hardware. Vinyl is cheaper upfront but quickly becomes brittle in freezing snaps and sags under the weight of wet pine needles. Steel offers exceptional rigidity for homes under towering Douglas firs but comes at a 30 to 50 percent premium. High-end copper can run $30 to $50 or more per linear foot, typically reserved for historic restorations in neighborhoods like Queen Anne or Capitol Hill.
Why five-inch vs. six-inch troughs matter in the PNW
Many older homes around Seattle were built with five-inch K-style gutters. If you are replacing a 200-foot run, upgrading to six-inch gutters is often worth the modest ten to fifteen percent cost increase. A six-inch gutter holds about forty percent more water volume than a five-inch gutter. When heavy fall downpours hit Snohomish or King County, or when fir needles and bigleaf maple foliage temporarily restrict flow, six-inch gutters prevent the dreaded water sheet spilling over the front edge and washing out foundation plantings.
The hidden cost factor: rotten fascia repair
A gutter installer will not hang fresh metal on rotten wood because the hidden bracket screws will pull right out under the first heavy winter rain. If overflowing gutters have soaked your cedar or primed pine fascia over several wet winters, those sections need replacement. Repairing rotten fascia, priming all cut ends, and blending exterior paint is finish carpentry work. When you bundle those minor structural touch-ups into a handyman half-day or full-day carpentry visit, you save substantial time and protect the new gutter installation from premature sagging.
Gutter guards and downspout routing
When replacing 200 feet of gutters, homeowners frequently ask about leaf guards. Micro-mesh covers add between $6 and $12 per linear foot. While they keep out large alder and maple leaves, they can sometimes shed water right off steep roofs during torrential cloudbursts, and pine needles can still lodge in the mesh. Ensuring your downspouts empty safely into city storm drains or onto dedicated kick-out extensions away from the crawlspace foundation is far more critical for keeping your basement dry.
Why it happens
Gutter pricing is determined by linear footage, profile size, metal type, downspout count, and site access. In King and Snohomish counties, five-inch or six-inch K-style aluminum gutters are the standard defense against our eight months of steady Pacific Northwest drizzle and sudden atmospheric rivers. Two hundred linear feet is the typical perimeter for a medium-sized single-story rambler or an average footprint two-story home. The real variance in cost usually comes down to what lies behind the metal. Because our climate stays damp for months at a time, failing gutters frequently trap moisture against the fascia board. If the wood behind the old gutter is decayed, that rot must be cut out and repaired before hanging new troughs, which quickly adds carpentry labor and exterior paint costs to the bottom line.
How to diagnose it
- 1Measure the total perimeter of your roof edges at ground level, adding ten feet of vertical run for each existing downspout drop.
- 2Inspect the existing fascia board with a flathead screwdriver behind seams or corners to check for soft, spongy wood rot.
- 3Look for signs of sagging, pulling away from the rafter tails, or rust stains trailing down the siding.
- 4Count the total number of corners, end caps, and downspout tie-ins, as each fitting requires custom hand cuts, sealant, and extra labor.
- 5Note roof height and ground obstacles like steep slopes, mature rhododendrons, or delicate deck glass railings that require specialized staging.
DIY vs. professional
DIY-friendly if…
Sectional vinyl or aluminum gutter kits from a hardware store can work for a simple, single-story garden shed or detached garage.
Call a pro when…
Whole-home replacement requires a continuous seamless roll-forming machine on a truck, proper slope calculations for heavy rain runoff, and insured ladder work.

What we see on Home Health Assessments
Around 74% of PNW roofs we assess show active moss establishment — accelerates shingle wear by an estimated 3–5 years if untreated.
Caught early on assessment: $220–$650 · Left until failure: $3,500–$22,000
During a Home Health Assessment, we evaluate gutter pitch, look for hidden fascia rot behind back lips, and confirm downspouts discharge at least five feet away from your foundation.
