Replacement quotes on similar-looking Kent homes can land a thousand dollars apart — and both can be honest. Here's what actually moves the number.

South King County replacement pricing runs $9 to $16 per linear foot installed for seamless aluminum, and the typical Kent home carries 130 to 220 feet of gutter. Multiply honestly and most projects land between $1,400 and $3,000 — before the four variables below adjust a specific home inside or beyond that band.
Stories and access. Second-story fascia slows everything: taller ladders, staging, more careful work. The Valley's ramblers price at the friendly end; East Hill two-stories and homes with walk-out basements price higher for the same footage.
Corners and complexity. Every corner is hand-formed and sealed, and Kent's split-levels — a staple of the 1970s and 80s stock — drain several small roof planes through more corners per foot than any simple rectangle.
Capacity upgrades. Moving from builder-standard 5-inch to 6-inch troughs with 3x4 downspouts adds modestly to the bill and substantially to storm performance. On larger rooflines it's the right money.
Material. Aluminum is the workhorse; half-round runs $14 to $24 per foot for traditional architecture, and copper starts around $35 for the homes that warrant it.
A 1980s East Hill split-level: 160 linear feet, seven corners, two stories at the rear, five downspouts. At a blended $11 to $13 per foot, the seamless aluminum replacement lands around $1,750 to $2,100 with tear-off and haul-away included. Upgrading the two rear runs to 6-inch adds a couple hundred dollars; micro-mesh guards installed in the same visit cost meaningfully less than a separate guard project later. A lakeside home with 240 feet and complex valleys might land near $3,500 on the same per-foot honesty — the spread is the house, not the contractor.
Exact footage per run and profile size. Downspout count, sizes, and where each one discharges. Tear-off and haul-away included. Fascia inspection notes. Hanger type and spacing. A total, a timeline, and a workmanship guarantee — in writing. A quote that skips the footage is a quote that can grow later; line items can't.
The replacement service page covers the full process, and on-site written estimates are free across Kent and South King County.
The overpays are predictable: paying two-story rates for a rambler because nobody itemized the footage; accepting a "whole job" price that quietly assumed 5-inch profiles the roofline outgrew years ago; and re-buying repairs season after season on a system already past design life — the most expensive gutter money in Kent is the $400 spent annually patching a $2,000 replacement.
The underpay is subtler: taking the cheapest bid and getting .027-gauge metal on wide hanger spacing. It looks identical on install day, and it fails in year six under an ice load or a wind-driven storm. Gauge, hanger spacing, and downspout count are where cheap quotes hide — which is why they belong in writing on every bid.
