Gutter Replacement Cost Calculator

How this calculator prices a replacement

Four lines can appear on the estimate, and only one of them is affected by how tall the house is. That asymmetry is the most useful thing to understand here, because it explains why a two-storey quote is not simply a single-storey quote scaled up.

The sectional-to-seamless step is the decision most homeowners actually face. Seamless runs about $2–$4 more per foot and is formed on site in one continuous length per run, which removes the joints that are the usual place a gutter starts leaking. On 200 feet that is $400–$800 to eliminate the most common failure mode of the thing you are buying.

A worked example, step by step

Drop the guards and the same job is $2,310–$4,120. That single option is between 38 and 49 percent of the total, which makes it by far the largest discretionary decision on the page — larger than the choice between sectional and seamless, and larger than the story multiplier.

The downspout count is derived rather than chosen: one drop per 35 linear feet of gutter, rounded, with a floor of one. If a contractor's proposal has noticeably fewer drops than that for the same footage, it is worth asking why, because too few downspouts overwhelms the gutter at the far end of a long run regardless of how good the gutter is.

What the story multiplier is really paying for

A 25 percent uplift for a second storey and 50 percent for a third is not a height surcharge in the arbitrary sense. It prices a genuinely different job: longer ladders, stabilisers, a second person to foot them, more time repositioning, and a slower pace because a fall matters more.

It applies only to the gutter line in this model, which is a defensible simplification — hanging the gutter is the part done at height for the whole run, while removal and guard fitting happen alongside it and downspouts are largely worked from the ground down. Treat a quote that applies a blanket height premium to every line as worth questioning.

Access can also break the model entirely. A house on a slope, a conservatory beneath the eave, or landscaping that will not take a ladder foot can turn a routine two-storey job into one needing staging or a lift. None of that is priced here, and it is the most common reason a real quote exceeds this estimate.

Who does this work and what moves the rate

Gutters are hung by the exterior trades. The Bureau of Labor Statistics reports 124,600 of the 135,490 US roofers (SOC 47-2181) employed in foundation, structure and building exterior contracting — the industry that does this work — at a May 2025 mean hourly wage of $27.95 and a 10th-to-90th spread of $18.01 to $39.29.

For scale on where this sits in a build, NAHB's 2024 construction-cost survey puts exterior finishes — the stage carrying roof drainage — at 13.4 percent of the cost of constructing a new home, behind interior finishes at 24.1 percent, major system rough-ins at 19.2 percent and framing at 16.6 percent.

Seamless gutter is also a machine-dependent product. It is rolled on site from coil stock by a forming machine on a trailer, which is why the trade is dominated by specialists rather than general contractors, and why a specialist is usually cheaper for this specific job than a roofer subcontracting it out.

What this estimate excludes

• ·Fascia repair. Gutters are hung off the fascia, and gutters get replaced because they have been overflowing. Soft fascia is common and is carpentry.
• ·Underground drainage. Tying downspouts into buried pipe is excavation.
• ·Painting. New gutters on old trim frequently make the trim look worse.
• ·Disposal beyond the removal line. The $1–$2 per foot covers taking them down; skip hire on a large job may be separate.
• ·Anything above three storeys. The access method changes and this model stops.
