2026 Idaho Cost Ranges at a Glance: Category 1 (clean water, minor): $1,200–$4,500 · Category 2 (gray water, appliances): $4,000–$8,500 · Category 3 (sewage/flooding): $7,500–$20,000+ · Mold remediation added: +$1,500–$6,000 · Most homeowner insurance covers sudden water events but not gradual leaks.
One of the first things Idaho Falls homeowners want to know after a pipe bursts or a basement floods is: what is this going to cost? The honest answer depends on three things — what category of water caused the damage, how large an area was affected, and how quickly you called for help. This guide breaks down real pricing ranges for restoration work in Southeast Idaho so you know what to expect before anyone sets foot in your door.
The Single Biggest Factor: Water Category
The IICRC S500 Standard classifies water damage into three categories based on contamination level. This directly determines what equipment, labor, and materials are required — and therefore what the job costs.
Category 1: Clean Water ($1,200–$4,500)
Category 1 comes from a clean source: a broken supply line, a malfunctioning refrigerator water line, a toilet supply hose, or an overflowing sink fed by city water. There's no sewage, no gray water from appliances — just clean water that got somewhere it wasn't supposed to be.
Because the water itself isn't contaminated, Category 1 jobs focus on extraction, drying, and repairing any materials that were soaked. If you catch it fast — within a few hours — costs stay in the lower range. If the water ran overnight or over a weekend, costs climb because more material absorbed moisture and some drywall or flooring may need to come out.
Typical Category 1 job: Washing machine supply hose breaks, floods laundry room and adjacent hallway. Extraction, drying equipment for 3–4 days, replace carpet pad and a section of drywall: $1,800–$3,500.
Category 2: Gray Water ($4,000–$8,500)
Category 2 involves water with some level of contamination — not sewage, but not clean. This includes overflow from dishwashers, washing machine drain water, aquarium water, or water that has been sitting long enough to grow bacteria. HVAC condensation that has pooled and grown mold also falls here.
Category 2 jobs require antimicrobial treatment of all affected surfaces, not just drying. Porous materials (carpet, insulation, some drywall) in direct contact with Category 2 water are typically removed rather than dried in place. This adds to both material and labor costs.
Typical Category 2 job: Dishwasher fails during a cycle, floods kitchen and soaks under the cabinets. Full extraction, cabinet base removal, subfloor assessment, antimicrobial treatment, drying, and reinstall: $4,500–$7,500.
Category 3: Black Water / Sewage ($7,500–$20,000+)
Category 3 is the most expensive and the most urgent. This includes raw sewage backups, toilet overflows with waste, river or storm floodwater entering the home (which carries contaminants from runoff and soil), and any Category 1 or 2 water that has been sitting for more than 72 hours.
Every porous material that touched Category 3 water must be removed and disposed of — there's no drying it safely. Drywall, insulation, carpet, pad, and sometimes subfloor all get torn out. The space is treated with industrial-strength antimicrobials before any reconstruction begins. These jobs also require proper disposal of contaminated materials under Idaho regulations.
Typical Category 3 job: Sewer backup floods a finished basement (600 sq ft). Full demolition of affected drywall, flooring, insulation. Antimicrobial treatment. Full reconstruction: $9,000–$18,000+.
What Else Drives Cost Up (or Down)
Response Time
This is the variable you control. According to the EPA's guidance on mold and moisture, mold can begin growing within 24–48 hours of water exposure. A job where we're called the same day extraction starts has lower total cost than the same damage that sat for three days before anyone noticed. Water migrates — it moves through drywall, under floors, and into wall cavities. Every hour increases the affected area.
Real-world impact: A Category 1 leak caught in 2 hours might cost $1,500. The same leak running for 48 hours could be $5,000–$8,000 — because now there's mold risk, more drywall is affected, and drying time is longer.
Affected Square Footage
Restoration work is largely priced by the square footage of affected area. A small bathroom overflow that stayed contained costs far less than a burst pipe that ran through three floors. Commercial equipment rental, labor hours, and material replacement all scale with size.
Materials Affected
Hardwood floors are more expensive to dry (or replace) than vinyl. Finished basements cost more to restore than unfinished ones. Plaster walls in older Idaho Falls homes can be harder to work with than modern drywall. Kitchen or bathroom damage involving cabinetry adds significant cost.
Mold Already Present
If mold has started — which happens after 24–48 hours of untreated moisture — mold remediation must happen before reconstruction. Add $1,500–$6,000 depending on extent. This is why immediate response is so important.
Structural Damage
Water that has saturated floor joists, load-bearing walls, or a foundation adds cost for structural assessment and potentially structural repairs. This is rare in average residential jobs but common in severe flooding or long-running leaks.
Idaho-Specific Pricing Factors
Southeast Idaho has a few factors that influence restoration costs locally:
- Winter freeze-thaw cycles: Frozen pipes are among the most common water damage causes in Idaho Falls. Because they often burst all at once when the pipe thaws, the volume of water released can be substantial. Pipes that freeze and burst often affect multiple rooms.
- Irrigation season: Spring and summer irrigation increases ground saturation and can push water into basements through foundation cracks. Costs here depend heavily on how far water has traveled through the foundation.
- Older housing stock: Many Idaho Falls homes were built in the 1950s–1980s. Older plumbing, galvanized steel pipes that corrode, and original drywall formulations can all affect restoration cost and complexity.
- Travel time from larger markets: Idaho Falls is a smaller market than Boise or Salt Lake. Equipment and labor are locally sourced when you work with a local company like Home Pride Restoration — you're not paying for a franchise crew driving from a regional hub.
Does Homeowners Insurance Cover Water Damage?
Most standard homeowners insurance policies cover sudden and accidental water damage — a pipe that unexpectedly bursts, an appliance that suddenly fails, a roof that leaks after a storm. What they typically do not cover:
- Gradual leaks (a slow drip under a sink that went unnoticed for months)
- Flooding from outside the home (requires separate flood insurance through the NFIP)
- Sewer backup (often requires a separate endorsement)
- Damage from deferred maintenance (a roof that's been deteriorating for years)
We work directly with insurance adjusters on every applicable claim. We document the damage thoroughly from the moment we arrive — moisture readings, photos, affected area maps — so your claim has what it needs. Homeowners who call us often find the insurance process significantly smoother than those who try to handle it themselves.

Why Calling Faster Reduces Your Total Cost
This is worth saying plainly: the single most cost-effective thing you can do after discovering water damage is call a professional immediately. Not tomorrow. Not after the weekend.
Professional emergency response within the first 24 hours consistently reduces total restoration costs by 40–70% compared to delayed intervention. The math is straightforward — less water absorbed means less drywall removed, shorter drying cycles, lower equipment rental, and no mold remediation. The restoration industry's own data, compiled by the IICRC, backs this up.
