New seamless gutters in Boise start around $8 to $15 per linear foot for the popular system, 5-inch K-style aluminum with 2x3-inch downspouts. Steel runs higher, specialty profiles step up, and copper sits at the premium end. The total comes down to your footage, the material, the profile, and how complex the roofline is.
What replacement costs in Boise
For 5-inch K-style aluminum with 2x3-inch downspouts, plan on roughly $8 to $15 per linear foot. Steel runs higher and handles snow load better. Half-round and box profiles step up from aluminum. Copper is the premium choice. Two-story homes and complex rooflines add labor. We scope your exact footage and give a fixed price before work starts.
Repair or replace?
Many problems are genuinely repairable, and a repair is often the smarter dollar. Most repairs run $100 to $900. Past that, replacement is usually the better value than patching the same gutters again. Replacement makes sense when the system is undersized, sagging across long runs, or worn enough that one leak is the first symptom.
Materials and sizing for Boise homes
Aluminum is the best value for most homes, lightweight and rust-resistant. Steel steps up the strength for heavy snow and ice. Copper is the premium, long-life choice for historic and high-end homes. Worth knowing here: the City of Trees has a lot of older North End and Bench homes built with basic 5-inch gutters that are undersized for the roof above them. Stepping up to 6-inch gutters and bigger downspouts is a common fix.
