What does it cost to replace gutters in the Seattle area?
Short answer
For a typical Seattle-area home, replacing gutters costs between $15 and $30 per linear foot installed. The final price depends on the material you choose, such as aluminum or steel, the height of your home, and the complexity of its roofline. A complete replacement on a medium-sized house often falls in the $3,000 to $7,000 range.
Key Factors That Determine Gutter Replacement Cost
The primary driver of cost is the total linear footage of gutters your home needs. Material is the next biggest factor: seamless aluminum is the most popular choice in the Seattle area for its balance of cost and durability. Vinyl is cheaper but less durable, while steel is stronger but more expensive and susceptible to rust. Other costs include labor, which increases significantly for two-story or three-story homes, fees for removing and disposing of the old gutters, and the quantity of downspouts required.
Why Seamless Aluminum is the PNW Standard
We almost always see seamless aluminum gutters installed on modern homes. Unlike sectional gutters that come in 10-foot pieces, seamless gutters are formed on-site from a single coil of aluminum to the exact length of your roofline. This drastically reduces the number of seams, which are the most common points of failure and leaks. Aluminum won't rust, holds paint well, and can easily handle the volume of water we get in Western Washington, making it the best value for most homeowners.
Don't Ignore Fascia and Soffit Rot
Failing gutters are a leading cause of rot in fascia boards and soffits. If you see peeling paint or dark stains on the wood behind your gutters, it's a sign of chronic overflow. Simply installing new gutters over rotted wood is a critical mistake, as the new fasteners won't hold securely. As general contractors, My House Spouse can repair or replace any rotted fascia boards, ensuring your new gutter system has a solid foundation to attach to for decades of performance.
Proper Slope and Downspout Placement is Critical
A new gutter system is only effective if it's installed correctly. Gutters must have a slight, consistent slope, typically about a quarter-inch for every 10 feet, to guide water toward the downspouts without it pooling. Downspouts must be numerous and large enough to handle the water volume from your specific roof area during a heavy downpour. Finally, we always ensure downspouts terminate into extensions that carry water at least 4 to 6 feet away from your foundation to prevent hydrostatic pressure and basement leaks.
Why it happens
Gutters fail primarily due to the relentless wear and tear of the Pacific Northwest climate. Heavy, year-round rain, combined with falling leaves, pine needles, and moss, creates frequent clogs. This trapped water becomes incredibly heavy, causing gutters to sag, pull away from the fascia boards, and eventually overflow. Over time, standing water can cause galvanized steel gutters to rust through, while vinyl gutters can become brittle from UV exposure and crack under the weight.
How to diagnose it
- 1During a rainstorm, look for water cascading over the edges of the gutter instead of flowing to the downspout; this is a telltale sign of a clog or improper slope.
- 2From the ground, scan the length of your gutters for visible sagging, bowing, or sections pulling away from the house.
- 3Inspect the fascia boards (the wood directly behind the gutters) for peeling paint, dark stains, or soft spots, which indicate chronic water overflow.
- 4Check for cracks, holes, or significant rust, especially at the seams and corner joints where sections are connected.
- 5Look for pools of water or eroded soil around your foundation after it rains, suggesting that downspouts are clogged, disconnected, or not directing water far enough away.
- 6Find significant amounts of shingle granules in your gutters, which indicates your roof is aging and may not be channeling water effectively.
DIY vs. professional
DIY-friendly if…
A homeowner can often seal minor leaks in a gutter joint with sealant or re-secure a loose hanger if they can work safely from a ladder.
Call a pro when…
A full gutter system replacement should be handled by a professional installer to ensure safety, proper slope for drainage, and secure attachment to the home.

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 inspect the entire gutter system for proper attachment, slope, and signs of overflow. We check for water damage on fascia boards and soil erosion near your foundation, giving you a complete picture of your home's rainwater management health.
