Gutter replacement
Gutter Replacement in Boise, ID
When patching stops making financial sense — the old system comes off, the fascia gets checked and repaired, and new seamless gutters go up in a single day.
Gutter replacement in Boise, ID averages $2,705 to $3,660 for a complete home system and finishes in one day on most properties. That covers tear-off and disposal of the failed gutters, inspection and repair of the fascia behind them, and 150 to 200 feet of new seamless gutter with four to six downspouts.
Replacement is the right call when the system has stopped being repairable — not when it looks tired. Plenty of Boise homes get sold a full replacement when a $300 rehang and reseal would have bought another eight years. The section below is the honest test for which side of that line your gutters are on.
When gutter replacement beats another repair
Gutter replacement beats repair once failures stop being isolated. One sagging run on an otherwise sound system is a repair. The same system failing in a new place every spring is a system at end of life. These are the specific conditions that push a Treasure Valley home into replacement territory.
- Rust perforation on galvanized steel. Once pinholes appear, they are appearing everywhere the coating has worn — patching one is patching the first of many.
- Sectional gutters leaking at multiple joints. Resealing buys two or three seasons here; Boise freeze-thaw cycling breaks the bond again.
- Spike-and-ferrule hangers throughout. If the front face is dotted with nail heads, the fastening system itself is obsolete and the run will keep pulling loose.
- Fascia rot behind the gutter. Soft board cannot hold a hanger. Once the wood goes, the gutter comes off with it during the repair anyway.
- Chronic overflow on a clean gutter. That is undersizing, and you cannot repair a 5-inch gutter into a 6-inch one.
- Vinyl gutters more than about eight years old. UV at Boise's elevation plus winter cold makes vinyl brittle — it cracks at the fasteners and shatters instead of bending.
The 40% rule: add up what the outstanding repairs would cost. If that total exceeds roughly 40% of a full replacement, replace. Below that, repair and put the replacement off — a well-maintained aluminum system can run 30 years.
The replacement process on a Boise home
The replacement process runs in a fixed order, and the middle step is the one that separates a thorough job from a fast one.
First, the old gutters and downspouts come down and get loaded out — aluminum and copper go to recycling rather than the landfill. Second, the exposed fascia board gets inspected end to end while it is visible, which is the only time in 20 years anyone will see it. Soft spots get probed, and rotted sections are replaced or repaired before anything new is hung. Third, new seamless runs are formed at the curb and cut to exact eave lengths, with corners fabricated and outlets punched. Finally, the runs are hung on hidden hangers at 24-inch spacing, pitched about a quarter inch per 10 feet, sealed at every joint, and water-tested before anyone leaves.
Fascia repair — the part nobody quotes up front
Fascia repair is the single most common change order on a gutter replacement, and it is worth understanding before you compare bids. The fascia is the horizontal board the gutter hangs on. When gutters overflow for years, water runs down behind the trough and soaks that board.
On Boise homes the damage concentrates in predictable places — under roof valleys, at the low end of long runs, and on north-facing eaves where the board stays wet and shaded through winter. Fascia repair runs roughly $8 to $20 per linear foot depending on whether it is a scarf-in patch or a full board replacement, and whether the soffit has to come down for access. An honest quote flags fascia as a possible add-on rather than pretending it cannot happen.
Upgrades worth taking during a replacement
A replacement is the cheapest moment to change the system, because the labor to remove and hang is already in the price. Four upgrades are worth considering while the crew is on site.
| Upgrade | Added cost | Worth it when |
|---|---|---|
| 5-inch to 6-inch gutter | +$2–$4 per foot | Steep roofs, long runs, valleys, metal roofing |
| 2x3 to 3x4 downspouts | +$3–$6 per downspout foot | Pine needles, chronic downspout clogs |
| Gutter guards | +$6–$25 per foot | Mature cottonwood, elm, or pine overhead |
| Buried drain lines | Varies with trench length | Clay or caliche soil holding water at the foundation |
The sizing upgrade is the one most Boise homeowners should take. Production builders across Meridian, Kuna, and Star installed a lot of 5-inch gutter with minimum outlet counts on two-story homes with steep roofs. Replacement is the moment to fix that, and it costs a few hundred dollars rather than a few thousand.
Replacing gutters on older Boise homes
Older Boise homes bring their own replacement considerations, especially in the North End, East End, and the pre-war blocks of Nampa and Caldwell. Three issues come up repeatedly.
Original fascia on 1900s to 1930s homes is often full-dimension lumber that is still sound but has been drilled through by decades of spike hangers. Second, many of these homes have narrow or nonexistent eave overhangs, which means the gutter takes water at high velocity straight off a steep roof — a case for 6-inch and for a slightly deeper gutter position. Third, historic districts and design guidelines can affect visible profile and material choice, which is one reason half-round and copper come up more often on these houses than anywhere else in the valley.
What a replacement quote should include
A replacement quote should be specific enough that you can compare two bids line by line. Ask for these items in writing.
- Total linear feet of gutter and total feet of downspout, listed separately.
- Material, gauge (.027 or .032 aluminum), and color.
- Gutter size and profile — 5-inch or 6-inch, K-style or half-round.
- Downspout count, size (2x3 or 3x4), and where each one discharges.
- Hanger type and spacing.
- Tear-off and disposal, stated as included.
- Fascia repair rate per foot, in case it is needed.

Gutter replacement questions
How much does gutter replacement cost in Boise?
Replacing gutters on an average Idaho home costs $2,705 to $3,660, which covers roughly 150 to 200 linear feet of seamless aluminum plus downspouts, tear-off, and disposal. Smaller single-story homes can come in near $1,400 to $2,000. Copper replacements on larger homes run well past $8,000. Fascia repair, if needed, adds $8 to $20 per linear foot of board.
How long do gutters last in Idaho?
Service life in the Treasure Valley depends almost entirely on material. Seamless aluminum lasts 20 to 30 years, galvanized steel 15 to 25 years before rust perforation, copper 60-plus years, and vinyl often fails inside 10 because Boise UV at 2,700 feet plus deep winter cold makes it brittle. Freeze-thaw cycling is the main accelerant on every material — it works fasteners loose and splits sealed joints.
Should I replace my gutters when I replace my roof?
Usually yes, and the sequencing matters. Replacing gutters at the same time as a roof avoids paying twice for staging, prevents damage to new gutters from tear-off debris, and lets the roofer set drip edge to feed the new gutter properly. If your gutters are more than 15 years old when the roof goes on, replacing them together is almost always cheaper than doing it two years later.
Can you replace just one section of gutter?
Yes, though there are two caveats. A single seamless run can be replaced independently and will match if the color and profile are still available — aluminum coil colors do get discontinued. The bigger issue is that a failed section on a 25-year-old system is usually a preview, not an outlier. We will quote both the section and the whole house so you can compare. See gutter repair for spot fixes.
What happens to my old gutters?
Old gutters come down, get loaded, and leave with us. Aluminum and copper are recycled rather than landfilled — copper in particular carries real scrap value that we credit against the job on larger tear-offs. The work area gets magnet-swept for screws and nails before we leave, which matters when the debris zone includes a driveway.
Do I need to be home during a gutter replacement?
Not for the whole day. All the work is outside, so access to the house is not required. It helps to be available at the start so we can confirm downspout placement decisions with you, and at the end for the walk-through. What we do need is clear driveway and side-yard access — the forming truck needs to park where coil can feed out in a straight line.
