How much does it cost to replace gutters on a 2,000 square foot house?
Short answer
In the Seattle area, replacing gutters on a typical 2,000 square foot home usually costs between $1,800 and $3,800. The final price depends on roof pitch, multi-story access, and whether rotted fascia boards hide behind the old metal.
Calculating Footage and Material Choices
A 2,000 square foot two-story home often has a smaller roof footprint and fewer linear feet of gutter than a sprawling single-story rambler of the exact same square footage. Seamless aluminum in five-inch K-style or six-inch fascia style is standard across King and Snohomish counties. Six-inch gutters cost about fifteen to twenty percent more than five-inch gutters, but they handle the heavy downpours and pine needle loads common in our region far better without spilling over the front lip.
The Hidden Fascia Rot Problem in the PNW
Water follows gravity and surface tension. When older gutters back up with maple seeds or hemlock needles, water wicks backward under the shingles and saturates the 1x6 or 2x6 fascia boards. Hanging new gutters over rotted wood is a waste of money, because the threaded hidden hangers will pull free during the first heavy snow or wind event. Budget an extra $500 to $1,500 if sections of your eaves need carpenter attention, prime paint, and solid backing before the gutter installers arrive.
Downspouts and Ground Drainage Realities
New gutters are only as effective as the ground system receiving the discharge. A full replacement estimate should include adequate three-by-four-inch downspouts rather than restrictive two-by-three-inch drops. If your downspouts empty directly against your concrete stem wall, water will find its way into your crawlspace or basement. Plan for downspout extensions or tight-line connections to move roof runoff at least five to ten feet clear of your foundation.
Bundling Exterior Repairs with House Spouse
Dedicated seamless gutter fabricators produce long, single-piece metal troughs from trailer-mounted machines, but they rarely perform comprehensive carpentry, soffit repairs, or exterior painting. House Spouse routinely inspects your roofline, repairs rotted rafter tails and fascia trim, and paints fresh timber ahead of installation. We bundle minor exterior repairs into our $580 minimum service visit, with additional time billed at $145 per hour plus materials, keeping your roofline solid for the next thirty years.
Why it happens
A standard 2,000 square foot home generally requires between 140 and 200 linear feet of gutters, depending on whether it is a simple single-story ranch or a complex multi-level layout with multiple gables and dormers. In western Washington, standard continuous seamless aluminum gutters are the benchmark because sectional gutters with seams inevitably leak under sustained winter rains. The biggest variable in overall project cost is not just the metal itself, but the hidden wood rot behind it. Decades of overflowing rainwater, trapped fir needles, and failed sealants allow water to soak into the primed sub-fascia. If the wood behind the gutters is soft or punky, new gutter hangers cannot hold a solid bite, meaning carpentry repairs must happen before new gutters hang.
How to diagnose it
- 1Estimate your total run by measuring the exterior perimeter of the roof edges, adding ten feet per downspout drop.
- 2Inspect the corners and end caps after a steady rain for active dripping or water staining along the siding.
- 3Look up from the ground along the gutter line to check for sagging sections, pulling spikes, or areas sloping away from downspouts.
- 4Poke the wooden fascia boards behind overflowing areas with an awl or screwdriver to check for spongy, rotted timber.
- 5Check ground-level splash blocks or foundation drains to see if downspouts are properly conveying water away from the crawlspace.

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 check gutter slopes, identify failing seams, and use moisture meters on your exterior fascia to catch hidden rot before you invest in new metal.
