What is the cost to install new gutters in the Seattle area?
Short answer
For a typical home in the Seattle area, installing new aluminum gutters costs between $12 and $35 per linear foot. The final price depends on the material chosen, the number of stories, the complexity of your roofline, and the condition of the underlying fascia boards. A full replacement is a significant project.
Key Factors Influencing Gutter Costs
The primary cost driver for gutter installation is the total linear footage of your roof perimeter, not the square footage of your house. Other major factors include the material you choose, the height of your home (two or three stories requires more labor and safety equipment), the number of corners and downspouts, and the cost of removing and disposing of the old system. Crucially, if the fascia boards that support the gutters are rotted, they must be repaired or replaced, adding to the project scope and cost.
Common Gutter Materials in the PNW
Aluminum is the most popular choice in Washington for good reason: it's affordable, lightweight, rust-proof, and available in many colors. Seamless aluminum K-style gutters are the standard. Galvanized steel is a stronger, more durable option that can withstand heavy debris or snow loads better, but it will eventually rust if the coating is scratched. Copper and zinc are premium, architectural choices that last for decades and develop a distinct patina, but come at a significantly higher price point.
Why Seamless Gutters are the PNW Standard
Seamless gutters are custom-formed on-site from a single piece of metal to the exact dimensions of your rooflines. This process eliminates the numerous seams found in sectional, DIY-style gutters. Since seams are the most common point of leaks and failure, seamless systems are far more durable and lower-maintenance, making them a wise investment for handling our long, rainy seasons.

Why it happens
Gutters require replacement when they no longer effectively channel water away from the foundation. In the Pacific Northwest, this is commonly caused by rust-through on older steel gutters, cracks and leaks at seams, or physical damage from ladders or fallen branches. Gutters can also pull away from the house due to the weight of water and debris, often a sign that the fascia wood behind them has started to rot.
How to diagnose it
- 1Look for visible signs of rust, holes, or cracks in the gutter troughs.
- 2During a rainstorm, watch for water overflowing the sides or leaking heavily from seams and corners.
- 3Inspect the fascia boards behind the gutters for peeling paint or dark water stains, which indicate leaks.
- 4Check if gutters are sagging, pulling away from the house, or have loose mounting spikes.
- 5Notice if downspouts are disconnected or if water is pooling near your foundation after rain.
- 6Listen for excessive dripping sounds long after the rain has stopped.
DIY vs. professional
DIY-friendly if…
A handy homeowner can replace a short, straight gutter section on a single-story structure like a shed using pre-fabricated parts from a home center.
Call a pro when…
A full gutter replacement should be done by professionals due to the risks of working at heights, the need for specialized equipment to create seamless gutters, and the importance of ensuring proper slope for drainage.
