2026 pricing guide
Gutter Installation Cost in Boise (2026)
Per-foot pricing by material and profile, what a 150-, 180-, and 220-foot home actually pays, and the six factors that separate a $2,400 quote from a $4,200 one.
Gutter installation costs $2,705 to $3,660 for a complete system on an average Idaho home, or $8 to $16 per linear foot in seamless aluminum. A typical Boise house needs 150 to 200 feet of gutter and four to six downspouts, and the work finishes in a single day. Labor in this market averages about $61 per hour.
That average conceals a wide range, because "gutter installation" covers everything from 130 feet of 5-inch aluminum on a single-story ranch to 260 feet of copper half-round on a custom home in Eagle. This page breaks the number apart so you can locate your own house inside it. For the work itself, see gutter installation in Boise, ID.
Installation cost per foot by material and profile
| Material & profile | Installed per foot | Service life | Notes |
|---|---|---|---|
| Aluminum, 5-inch K-style | $8 – $13 | 20–30 yrs | The Treasure Valley default |
| Aluminum, 6-inch K-style | $10 – $16 | 20–30 yrs | ~40% more capacity, 3x4 downspouts |
| Aluminum half-round | $12 – $20 | 20–30 yrs | Exterior brackets add labor |
| Galvanized steel | $10 – $16 | 15–25 yrs | Heavier, tighter hanger spacing |
| Galvalume steel | $13 – $18 | Longer than galvanized | Better in standing water |
| Corten weathering steel | $20 – $35 | 40+ yrs | Often fabricated rather than roll-formed |
| Copper K-style | $25 – $40 | 60+ yrs | Soldered joints |
| Copper half-round | $30 – $50 | 60+ yrs | Traditional profile, bracket-hung |
| Vinyl (sectional) | $4 – $8 | 5–15 yrs | Not recommended for Boise homes |
Downspouts price separately at $8 to $14 per foot for aluminum and $30 to $50 for copper. A two-story downspout is typically 20 to 25 feet, so budget $160 to $350 each on an aluminum system.
Installation cost by home size
Home size drives the total more than any other single variable. These figures assume seamless 5-inch aluminum with standard 2x3 downspouts, including tear-off on a replacement.
| Home | Gutter feet | Downspouts | Typical total |
|---|---|---|---|
| Small single-story ranch | 120 – 150 ft | 3 – 4 | $1,400 – $2,300 |
| Average two-story home | 160 – 200 ft | 4 – 6 | $2,300 – $3,700 |
| Large or complex roofline | 220 – 280 ft | 6 – 8 | $3,600 – $5,500 |
| Custom home, premium material | 240 – 320 ft | 7 – 10 | $8,000 – $16,000+ |
Measure it yourself first. Walk the perimeter and add up every eave that has or needs a gutter. Multiply by $10 for a rough aluminum midpoint. If a quote is wildly above or below that figure, ask which line item explains the difference — that question alone tells you a great deal about the contractor.
What drives installation cost up
Six factors explain most of the spread between quotes on the same house, in roughly this order of impact.
First, linear footage. Everything scales from it. Second, material. Copper costs three times aluminum for identical work. Third, corners. Every inside and outside miter is cut, riveted, and sealed by hand, so a house with eight corners costs more per foot than one with four. Fourth, stories and access. Second and third-story elevations need staging time, and at roughly $61 an hour that adds up quickly. Fifth, fascia condition. Rot found at tear-off adds $8 to $20 per linear foot of board. Finally, upgrades — 6-inch gutter, 3x4 downspouts, gutter guards, or buried drain lines.
Upgrades and what they add
| Upgrade | Added cost | Worth it when |
|---|---|---|
| 5-inch → 6-inch gutter | +$2 – $4 per foot | Steep roofs, long runs, valleys, metal roofing |
| .027 → .032 aluminum | Modest premium | Ladder access, hail, trees overhead |
| 2x3 → 3x4 downspouts | +$3 – $6 per downspout foot | Pine needles, repeat clogging |
| Gutter guards | +$6 – $25 per foot | Mature cottonwood, elm, or conifers |
| Downspout extensions | +$40 – $150 each | Nearly always — hardpan soil |
| Buried drain line + emitter | By trench length | Flat lots, clay, narrow side yards |
The 6-inch upgrade is the one most Boise homeowners should take. On a 180-foot house it is a few hundred dollars for roughly 40% more capacity, and it addresses the exact failure mode that builder-grade systems across Meridian and Star exhibit every spring.
New installation vs replacement pricing
New installation on a bare fascia costs less than replacement, typically by $300 to $800 on an average home. Replacement adds three things: labor to remove the old system, disposal, and the possibility of fascia repair once the board is exposed.
Replacement carries one hidden variable that new installation does not — existing drainage. If the old downspouts fed into buried lines, those lines need testing before the new system ties into them. Crushed or root-invaded corrugated pipe is a common discovery on older Boise properties, and it turns a gutter job into a drainage job. See gutter replacement.
Boise installation costs compared to national figures
Boise installation pricing runs modestly below national averages, driven almost entirely by labor. Aluminum coil is a commodity priced similarly everywhere; the Idaho labor rate around $61 per hour is lower than West Coast metro rates.
Two local factors offset some of that. The valley has a high share of two-story homes with steep roofs, so access costs appear more often here than in single-story markets. And demand from rapid growth in Meridian, Kuna, Star, and Caldwell keeps installers busy, which affects scheduling more than price.
Getting an accurate installation quote
An installation quote you can actually compare against another one should list all of the following.
- Measured linear feet of gutter and of downspout, separately.
- Material, gauge, size, profile, and color.
- Number of inside and outside corners.
- Downspout count, size, and discharge location for each.
- Hanger type and spacing in inches.
- Tear-off and disposal, stated as included or excluded.
- Fascia repair rate per foot.
- Total, with no deposit required to receive the quote.
Straight answers
Gutter installation cost questions
How much does it cost to install gutters in Boise?
Gutter installation in Idaho averages $2,705 to $3,660 for a complete home system. Per foot, seamless aluminum installs at $8 to $16, steel at $10 to $18, and copper at $25 to $45. A typical Boise home needs 150 to 200 linear feet plus four to six downspouts, and most installations finish in one day.
How much does seamless gutter installation cost per foot?
Seamless aluminum runs $8 to $13 per linear foot for 5-inch and $10 to $16 for 6-inch, installed. Half-round aluminum is $12 to $20. Seamless steel is $10 to $18, and seamless copper $25 to $45 with soldered joints. Those rates include forming the gutter on site, hanging, sealing, and disposal of packaging.
Is it cheaper to install gutters on a new home or a replacement?
New installation is cheaper, typically by $300 to $800 on an average home. There is no tear-off labor, no disposal, and no risk of discovering rotted fascia mid-job. New construction also allows free choice of downspout placement rather than inheriting an existing drainage path that may or may not still work.
What is included in a gutter installation quote?
A complete quote covers measured linear footage, material and gauge, gutter size and profile, downspout count and size, hanger type and spacing, sealing at all joints, and cleanup. On a replacement it should also state tear-off and disposal as included, and give the per-foot rate for fascia repair in case it is needed. Anything not written down is not in the price.
How much do downspouts add to installation cost?
Aluminum downspouts run $8 to $14 per foot, and a typical two-story downspout is 20 to 25 feet, so figure $160 to $350 each installed. Most homes need five or six. Upgrading from 2x3 to 3x4 adds a few dollars per foot and is usually worth it on properties with pine needles or chronic clogging.
Can I save money by installing gutters myself?
You can save on labor, but you give up the seamless process entirely — roll formers are contractor equipment, so DIY means sectional gutter with a joint every 10 feet. In Boise's freeze-thaw climate those joints are the first thing to fail. Between the joint count, ladder work at height, and getting pitch right within a quarter inch per 10 feet, the savings are smaller than they appear.
Do I need a permit to install gutters in Boise?
Gutter installation on an existing home generally does not require a building permit in the Treasure Valley, since it is not structural work. Related work can — fascia replacement beyond simple repair, or drainage tie-ins to a storm system. If a project involves buried drain lines crossing property lines or connecting to municipal infrastructure, check with the city or county before starting.
