Water Damage Restoration Cost in Boise (2026)

Water damage restoration in Idaho runs $1,200–$4,500 for Category 1 (clean) water, $4,000–$8,500 for Category 2 (gray) water, and $7,500–$20,000+ for Category 3 (black) water, per Home Pride Restoration's 2026 Idaho pricing guide. These are estimates, not fixed quotes. The bill depends on the water category, the affected area, and how fast drying starts.

• Category 1 (clean): supply-line water with no contaminants.
• Category 2 (gray): water with some contamination, like a washing machine overflow.
• Category 3 (black): sewage or heavily contaminated water — a health risk.

Idaho column: Home Pride Restoration. National column: NuBilt's 2026 range. PuroClean's 2026 guide puts the national average at about $3,860, with a typical range of $1,383–$6,370. Per square foot: $3–$4, $4–$7, and $7–$15 by category.

By size, NuBilt estimates $1,200–$5,000 for a single room (up to 200 sq ft), $4,000–$12,000 for multiple rooms, $8,000–$25,000+ for a whole floor, and $3,000–$20,000 for basements. Home Pride puts a finished 600 sq ft Idaho basement at $9,000–$18,000+ — common in Boise and Meridian.

NuBilt's 2026 guide lists the components: water extraction $300–$2,500, structural drying $1,000–$5,000, material removal $500–$5,000, antimicrobial treatment $300–$2,000, and reconstruction $1,000–$15,000. Restoration and reconstruction are different line items. PuroClean's 2026 guide is explicit that its figures cover mitigation and restoration only, which leaves painting, drywall replacement and flooring on a separate bill. The job gets your home dry; putting the sheetrock back is somebody else's invoice.

Ask every contractor for a written breakdown. PushLeads' 2026 pricing roundup lists labor at $75–$150 an hour, an emergency surcharge of $100–$300, drying equipment at $50–$150 per day, and travel charges of $50–$150 beyond about 20–30 miles.

The U.S. EPA's mold guidance “presents strategies to respond to water damage within 24-48 hours. These guidelines are designed to help avoid the need for remediation of mold growth by taking quick action before growth starts.” Its checklist asks: “Dry non-moldy items within 48 hours” and “Have building materials been wet more than 48 hours?” Mold does not wait for a contractor's schedule.

Small areas are DIY. The EPA says if the moldy area is “less than about 10 square feet (less than roughly a 3 ft. by 3 ft. patch), in most cases, you can handle the job yourself.” If water damage is extensive or mold covers more than 10 square feet, the EPA points to its professional guide.

Porous materials are different. The EPA warns that wet, moldy porous materials “may have to be discarded” — mold penetrates porous surfaces and can be impossible to remove completely.

Sudden, accidental water damage from inside the home is typically covered by a standard homeowners policy, says Progressive. Travelers says burst-pipe damage is often covered — but ignore a known leak and coverage may not apply. NAIC, the state insurance regulators, says policies usually cover frozen burst pipes when the homeowner took reasonable steps to keep them from freezing.

Standard policies exclude:

• Gradual damage and wear and tear. A sink leaking for months likely is not covered (Progressive).
• Flooding. Excluded from standard policies (Triple-I).
• Sewer or drain backup. Not covered by a typical policy or flood insurance; needs a separate endorsement, usually at nominal cost (Triple-I).
• Mold. Not covered unless it came from a sudden or accidental incident (Progressive).
• Aging water lines. Breaks from age, wear, poor installation, shifting soil, pests, or tree roots are excluded (Travelers).

Freeze prevention matters. Travelers recommends at least 55 degrees inside when you are away and draining plumbing for long absences. NAIC says policies generally require a minimum indoor temperature or shut-off water supply for vacant homes. Worth learning which rule your policy uses before the first Treasure Valley cold snap, rather than during the claim.

Home Pride Restoration's Idaho guide adds $1,500–$6,000 for mold remediation on a water damage job. If mold shows up, the bill grows. Nationally, mold remediation averages $2,300 in This Old House's 2026 guide, with a typical range of $1,200–$3,750 and $10–$25 per square foot.

Where the mold is changes the price. This Old House estimates a bathroom at $500–$1,000, crawl space $500–$2,000, basement $500–$3,000, attic $1,000–$4,000, HVAC $3,000–$10,000, and a whole house at $10,000–$30,000. By size: 50 sq ft $500–$1,250; 100 sq ft $1,000–$2,500; 200 sq ft $2,000–$5,000; 500 sq ft $5,000–$12,500; 1,000 sq ft $10,000–$25,000.

In Boise the pattern is basements and crawl spaces, which is where a finished lower level turns a drying job into a remediation job.

A sewer backup is Category 3 black water. Roto-Rooter warns that raw sewage “poses serious health risks and requires professional remediation,” which rules out handling it with a shop vac and a weekend. The City of Boise takes sewer odor, line backup, and construction complaints at (208) 608-7200 (general line (208) 608-7150). Staffed Monday–Friday, 8 a.m.–5 p.m., closed major holidays — a 2 a.m. backup will not reach a city operator. Call a licensed plumber or restorer first.

Emergency plumber pricing: $150–$500 for the after-hours service call plus $100–$200 an hour for labor, with typical emergencies running $300–$800+ total, per AllBetter's 2026 guide. Plumbing Price Guide lists a sewer backup at $300–$1,500 and a burst pipe at $500–$2,000.

A standard policy leaves sewer backup out. Triple-I says it takes a separate endorsement, so it is worth finding out whether yours carries one before you need it.
