Crawl Space Repair Cost
Crawl space repairs cost $1,500 to $15,000. In many situations, you’ll probably find you need a combination of repairs, cleaning and preventative measures. For example, if you have moldy, rotted beams, you’ll probably want to clean it, replace any damaged beams and install an encapsulation system to lower humidity levels and avoid the problem down the road.
Repair Type | Average Cost |
---|---|
Foundation | $2,000 - $7,000 |
Water Damage | $1,200 - $4,500 |
Insulation | $1,000 - $4,000 |
Structural | $1,500 - $5,000 |
Encapsulation | $1,500 - $15,000 |
Crawl Space Foundation Settling Repair Cost
Fixing a settling or sinking foundation costs $2,000 to $7,000 or more. You might need to replace or shore up supports, fix cracks and relevel the house. A pro typically secures it with either piers/piles or mudjacking.
- Piers and piles cost $1,000-$3,000 per unit.
- Mudjacking costs $600-$1,500.
You’ll also want to look at soil related issues that might cause future problems.
Wet Crawl Space Repair Cost
Repairing and cleaning water damage costs $1,200 to $5,100 with extreme flooding exceeding $9,000. Preventative measures, like encapsulation and waterproofing, can run $15,000 or more. You might have to restore or replace walls and/or individual wooden beams, which can range up to $2,000. Further actions increase that budget, like mold removal and fixing insulation damage.
Cost to Remove Insulation From Crawl Space
Crawl space insulation removal and replacement costs $1,000 to $4,000. Damaged or inadequate insulation affects energy efficiency. Price really depends on what type you get and whether you also waterproof the foundation.
- Installing batting insulation costs $1,000-$2,400.
- Installing spray foam insulation prices range from $1,300-$3,800.
- Basement waterproofing costs $2,300-$7,100. You’ll probably spend less on a crawlspace.
Plenty of insulation keeps air temps from coming through the floorboards. This keeps your home just where you want it. Updating or sealing a vented or unsealed space can help by keeping the outside air from entering in the first place.
Replacing Support Beam in Crawl Space Cost
Replacing a support beam costs $1,500 to $5,000. It really depends on how hard it is to get to, what material you use (wood or steel) and any other structural damage you might have. You’ll also need to fix the root cause of the problem, usually a settling foundation or water damage.

Crawl Space Cleaning Cost
Cleaning your crawl space professionally will range between $500 and $4,000. Most contractors charge based on three factors: the size of the space, condition and what they’re cleaning. For example, removing junk and construction debris won’t hurt your wallet much, but mold or pests runs into the thousands.
Type of Cleaning | Average Cost |
---|---|
Insects & Rodents | $200 - $4,000 |
Mold | $1,000 - $3,500 |
Pests/Rodents
Removing pests costs $175 to $525. Some homeowners report a complete pest removal, cleaning and sealing runs from $2,000 to $4,000. Warm, wet areas attract insects and rodents. Find a pest control service near you to remove unwanted guests and treat the crawl space to prevent their return.
Mold in Crawl Space Removal Cost
Mold remediation costs $1,150 to $3,350. If you have mold, you probably have moisture or water issues too. Dealing with moisture in your crawlspace with encapsulation, vapor barriers, sealing and dehumidifiers keeps this problem for happening again.
Mold, mildew and bacteria develop in crawl spaces and enter the home through the air. Exposure to mold and other microorganisms can cause or worsen respiratory illnesses like asthma and allergies.
Crawl Space Fungus Treatment Cost
Removing fungi other than your typical mold, like mushrooms, white mold and slime fungi costs the same as any mold, or $1,000 to $3,500. You’ll use the same treatments with the same professionals. Most of these other types of mold don’t present a direct threat to your home, but they can trigger allergic reactions and do indicate a high level of moisture. This just means that, eventually, wood rot molds will take over.
Reasons to Clean
Cleaning should always be your first step before any comprehensive repairs.
Hire a trained professional to clean the space or wear proper safety gear and follow all necessary precautions to avoid getting sick.
A specialist will have the knowledge, equipment, and protective gear to handle potentially dangerous materials and situations like:
- Pests
- Rodents
- Animal remains or waste
- Fiberglass insulation
- Asbestos
- Small areas
- Limited visibility
- Mold
- Sloped grade
