fha underwriter denied mortgage in nashville tn due to crawl space standing water - how to install sump pump and vapor barrier in 48 hours?

Question

we are buying a 1970s split-level home in nashville tn (east nashville). during the FHA appraisal, the appraiser noted 2 inches of standing water in the low corner of the crawl space and fungal growth across the subfloor joists.

the FHA underwriter issued an immediate loan suspension stating: 'crawl space must be dry, standing water extracted, active fungal growth remediated, and a functioning sump pump with sealed vapor barrier installed prior to closing.'

closing is in 6 days. can full standing water extraction, sump pump installation, and 20-mil vapor barrier encapsulation be completed in 48 hours in Nashville?

Direct Answer:  Yes, a certified environmental and waterproofing crew can extract standing crawl space water, install a commercial submersible sump pump with gravity discharge, remediate floor joists to <14.0% WME, and lay a sealed 20-mil poly vapor barrier within  36 to 48 hours  to satisfy FHA underwriting before your 6-day closing deadline. 
 Under HUD Handbook 4000.1, standing water in a crawl space is a non-negotiable structural and health deficiency. In Middle Tennessee limestone clay terrain, poor exterior grading channels storm runoff under foundation footings, where water pools and causes rapid  Stachybotrys  and  Penicillium  blooms. 
 The 48-hour FHA turnaround protocol: 
 
    Emergency Water Extraction:  Deploy commercial submersible trash pumps to vacuum all standing liquid water. 
    Subfloor Joist Antimicrobial Scrubbing:  Wire-brush and HEPA vacuum joists, applying EPA-registered botanical fungicide. 
    Perimeter Sump Basin Installation:  Dig basin in lowest elevation corner, install 1/2 HP Zoeller cast-iron sump pump with discharge line routed 10+ feet outside. 
    20-Mil Poly Encapsulation:  Cover 100% of crawl space floor with 20-mil virgin poly sealed 6 inches up foundation piers. 
    HUD-92051 Reinspection Package:  Deliver contractor certification and moisture log to underwriter.

As a certified home inspector: FHA reinspectors in Davidson County will specifically check that the sump pump discharge pipe drains to daylight at least 10 feet away from the house, not just dumping water right against the foundation wall outside.

Ensure your contractor routes the PVC line properly.

Once the work is finished, have your loan officer request the FHA Compliance Inspection Report (HUD-92051) immediately so the reinspector can sign off within 24 hours.

Contractor quoted $4,200 for perimeter French drain, sump pump with battery backup, and 20-mil poly. Does that sound standard for Nashville?

For a full interior perimeter drain with a commercial Zoeller sump pump and 20-mil vapor barrier, $3,500 to $5,000 is right in the sweet spot in Davidson County.

Antonio · Answer

Ensure the sump pump discharge line runs at least 10 feet away from the foundation and discharges to daylight with a freeze-proof freeze relief collar. FHA reinspectors will check the exterior discharge point.
