← Gutter cleaning bid calculator
Homeowners compare quotes on linear feet. Contractors who price that way lose the two-story jobs and overcharge the ranches. The trough length is the same; the minutes are not.
On a one-story eave a crew can walk most of the run from a single ladder set, or from the roof if the pitch is low. On a two-story eave every section is a new set, a longer carry, and a slower clean because one hand is managing reach and the other is scooping. A useful starting multiplier is about 1.6× on the one-story baseline — not 2×, because the trough itself did not get longer, and not 1×, because the access did.
Steep pitch stacks on top of that. Guards stack on top of that. Pine needles stack on top of that. A 40-foot two-story micro-mesh run in fir needles is a different job from 40 feet of open one-story leaf trough, even though both are “40 linear feet.”
Flushing and testing a leader is not included in a per-foot trough rate. Each downspout is minutes of its own, and a second-story leader takes longer to reach and confirm. A house with six downspouts and short eaves can take as long as a house with long eaves and two.
Screens and micro-mesh reduce how often a house needs service. They increase the time of the visit that still has to happen, because debris is under or in the covering. Price the visit you are actually doing. If guards mean the house is now once a year instead of twice, that shows up as visits-per-year, not as a discount on the hour.
The number a contractor should hold is the visit price that covers loaded labor, travel, disposal, overhead, and the margin they mean to keep — and the walk-away number below it. The implied dollars per linear foot is a sanity check, not the bid. The gutter cleaning bid calculator does that arithmetic from your own crew times. The starting multipliers are ballpark figures, not a standard.
A second story adds ladder moves, reach time, and a safety tax on every foot. The trough is the same length, but the minutes per foot are not. A common starting multiplier is about 1.6× for two stories on top of the one-story baseline, before pitch, guards, or debris.
No. Screens and especially micro-mesh slow a clean because debris has to be lifted out of or pulled through the covering. Guards reduce how often a house needs service; they do not reduce the time of the visit that still has to happen.
Use linear feet as an input, not as the price. Two houses with the same footage can differ by more than 2× in labor once stories, pitch, guards, pine needles, and downspouts are counted. Quote the visit, then look at the implied dollars per foot as a sanity check.
