Crawl Space Mold Removal in Arrington, TN

What happens when you call

The number on this page connects you to an independent local company that handles crawl space mold. On the phone, describe what you've found and whether water has collected under the house. A site visit should include moisture readings on the framing, a check of the vapor barrier, insulation, ductwork and plumbing, and a look at grading and downspouts outside. If the builder installed a crawl space dehumidifier or sealed vents, the inspector should check that they're working. Ask for photos and a written scope that explains the moisture source before any work is priced.

Cost factors

Angi reports national typical ranges of about $500 to $2,000 for crawl space mold remediation and $1,500 to $15,000 for encapsulation. Middle Tennessee prices vary, and Arrington jobs range from small cleanups to full encapsulations on large homes. The things that move the number most:

1. Square footage of the crawl space and how much of the framing is affected.
2. Clearance and access, including how many piers and duct runs the crew works around.
3. Volume of insulation and debris to remove.
4. Drainage fixes such as culvert or ditch work, downspout lines or a sump.
5. Liner, sealed vents and dehumidifier, if encapsulation is part of the plan.

Local conditions in Arrington

Williamson County emergency management names the Harpeth River and its creeks as the main local flood sources and warns that flash floods can come with little warning. Most streams and creeks in the county are the property owner's responsibility, and blocked culverts, ditches and drains can cause flooding on their own. On rural acreage, a clogged culvert near the drive can be enough to send water under a house. The May 2010 flood showed that 20 inches or more of rain can fall in the county within two days. A standard homeowner's policy does not cover flooding; coverage is available through the National Flood Insurance Program. Repairs to framing after remediation are permitted through the Williamson County Building Codes Division in Franklin, and electrical permits in the unincorporated county come through the State of Tennessee.

Checklist before the visit

• Clear the access door and any storage in front of it.
• Walk the yard after rain and note where water stands.
• Make sure culverts and ditches near the house aren't blocked.
• Look up the property on FEMA's Flood Map Service Center.
• Gather any prior inspection or builder warranty paperwork.
