Crawl Space Mold Removal in Portland, TN

What happens when you call

You'll be put through to an independent mold remediation company serving the Portland area. Tell them what you've seen or smelled, when water last got under the house, and whether the home is site-built over a crawl space or a manufactured home. They'll set a time to look. A thorough visit covers the whole underside of the house: moisture readings on the joists, the condition of the ground barrier and insulation, the ducts, any plumbing leaks, and how water drains around the foundation. You should leave with photos and a written plan that separates mold removal from moisture control.

What the price depends on

Angi lists national ranges of about $500 to $2,000 for crawl space mold remediation and $1,500 to $15,000 for encapsulation. Portland-area prices vary. Factors include the area of affected framing, clearance, insulation removal, drainage work, wood repair and whether a dehumidifier is installed. Licensing also varies by address here: Robertson County is one of the counties where residential jobs of $3,000 to under $25,000 need the state Home Improvement license, while Sumner County is not on that list. Jobs of $25,000 or more need a Tennessee contractor's license anywhere, with the S-F classification for mold remediation.

Local conditions in Portland

The Sumner County Flood Insurance Study singles out Donoho Branch as a frequent flooding source in Portland, tied to sinkholes and the area's drainage. The Portland Flood Channel, completed in 1997, was built to cut that flooding down, but heavy storms still test the area; the May 2017 flash flooding brought multiple rescues in Portland. Homes near the branch or over sinkhole-prone ground are the ones most likely to get water underneath. Elsewhere, the cause is usually humidity. About 11 percent of homes are mobile or manufactured, and the underside of those homes, behind the skirting and the belly wrap, can trap moisture much like a crawl space does. The median home dates to 1995. More than a third of homes are rented, and tenants can raise unfixed leaks with the City of Portland Building Codes Department, which also issues repair permits inside city limits.

Checklist before the company arrives

• Unlock or clear the crawl space door or skirting access panel.
• Note dates of any water under the house, including after the last big storm.
• Check whether downspouts empty right next to the foundation.
• Know whether your address is on the Sumner or Robertson County side.
• Turn off the HVAC if the ducts underneath look moldy, as EPA advises.
