Default scenario: 160 feet of 5-inch, with guards. Not a contract price. The band is the point total plus or minus 15%, a planning allowance we set for early estimates, not a measured accuracy. Prices include materials, labor, JKM overhead and fee, and 9.3% Washington sales tax. Working days on site are crew days. Design, permits and material lead times add calendar time before and between them.

| Downspouts | 5 ea | $725 |
| Gutter guards | 160 lf | $1,040 |

Notes
- Price assumes a one- or two-story eave the crew can reach with a pump jack or ladder.
Not in this band
- Hazardous-material abatement. Asbestos and lead are common on pre-1978 houses and are separately licensed work.
- Structural repair discovered after demolition.
- A new electrical panel, water service, or septic, unless that line is on this estimate.
- Design fees, except where a drawing line is shown.
- Financing and temporary housing. (Washington sales tax, 9.3%, is included in these prices.)
Planning band for Kitsap County. Not a bid. A site visit sets the number.
What the gutter estimate covers
The gutter estimate prices a gutter system from its length. You enter the run in feet, choose a 5-inch or a 6-inch gutter, and decide whether to add guards and whether to remove the old gutters. The desk adds downspouts on its own, working out how many from the length of the run.
The default is 160 feet of 5-inch gutter with guards and removal of the old run, so the first band is for a whole-house replacement.
What each line is
The gutter line is priced per foot and the size sets the rate. Downspouts are counted and priced per piece, with at least two on any run. Guards are priced per foot of gutter, and removal of the old gutters is priced per foot as well. You can switch guards and removal off to see what each adds.
Because every line scales with length, the band moves in a straight line as you change the run, and the hint under the length box tells you if you type a run outside the range the estimate covers.
What moves the number
Length is the biggest factor. Size is next, since 6-inch gutter costs more per foot than 5-inch and carries more water. Guards add their own per-foot line, so they are the first thing to switch off if you are trying to bring the number down.
Days on site follow the length, and a very small job is lifted to a minimum that the desk shows as its own line.
What is not in the band
The price assumes a one- or two-story eave that the crew can reach with a pump jack or a ladder. A taller eave, a steep lot or a roof edge with no safe access changes the method and the cost, and the desk does not guess at it. The band also leaves out hazardous-material abatement, structural repair such as rotted fascia found when the old gutters come off, design fees and financing. Washington sales tax is already included in the prices.
Whether gutters need a permit depends on the project, especially if they are part of a larger exterior job. Our permit guides explain which Kitsap office covers your address. Use the band to decide on guards and size, then ask for a site visit so we can check the fascia before we write the real estimate.

Questions
Gutters estimates: common questions
What does the gutter estimate assume before I change anything?
The starting band, $3,600 – $4,900, is the default scenario (160 feet of 5-inch, with guards). It prices the gutter, the downspouts, the guards and the removal of the old gutters from the length of the run.
How does the gutter estimate decide how many downspouts to price?
It works them out from the length of the run, at least two, roughly one for every 35 feet. A downspout is its own line, priced per piece, so a longer run adds both gutter and downspouts.
What is the difference between 5-inch and 6-inch gutters in the estimate?
A 6-inch gutter carries more water and costs more per foot. The desk prices the two sizes separately so you can see what the larger size adds to the same run.
What does the gutter estimate assume about access?
That the eave is one or two stories high and reachable by a crew with a pump jack or a ladder. A taller or harder-to-reach eave is outside the price and is something a site visit checks.
