New gutters on a typical DC-area home run $1,400 to $4,500 installed in 2026 for seamless aluminum — the standard choice — with copper and guard systems above that. Here’s the per-foot math, what drives the spread, and when replacement beats repair.
Gutter installation costs in 2026
| System | Installed cost per linear foot | Typical home (150–200 LF) |
|---|---|---|
| Seamless aluminum (5″) | $9 – $15 | $1,400 – $3,000 |
| Seamless aluminum (6″, steep/large roofs) | $11 – $18 | $1,700 – $3,600 |
| Steel | $12 – $20 | $1,800 – $4,000 |
| Copper | $30 – $60 | $4,500 – $12,000 |
| Gutter guards (added) | $6 – $15 | $900 – $3,000 |
| Downspouts | $8 – $15 each LF | included in quotes above |
What moves the price
- Stories and roofline: second-story work and complex rooflines add labor — the same footage costs more on a colonial than a rambler.
- Fascia condition: rotted fascia boards must be replaced before hanging gutters ($8–$20/LF) — the most common surprise line.
- Drainage plan: extensions and buried drains that move water away from the foundation are cheap insurance against a much more expensive basement problem.
Repair or replace?
Resecure sagging sections, reseal a joint, or replace a crushed downspout — those are $150–$600 repairs. Replace when gutters are pulling away in multiple places, seams leak faster than they’re sealed, or they’re original to a 25-year-old house. If the roof is due soon, do gutters after the roof, never before.

Frequently asked questions
How much does gutter installation cost per foot?
Seamless aluminum runs $9–$15 per linear foot installed in the DC area in 2026; 6-inch systems $11–$18; copper $30–$60. Most homes total $1,400–$4,500 in aluminum.
Are gutter guards worth it?
Under heavy tree cover — most of Montgomery County and NW DC — usually yes: $900–$3,000 in guards versus twice-yearly cleanings and the ice-dam risk of clogged gutters. On treeless lots, skip them.
How long do seamless aluminum gutters last?
20–30 years with basic maintenance — typically as long as the roof above them.
