Fix the crawlspace, and half the house's problems go with it.
Musty smells, high humidity upstairs, buckling floors and the pests that follow moisture almost always trace back to the same place. We seal it, dry it out, and fix what's already been damaged — in one scoped project, not a patch job.
Same crawlspace, four days apart
What a renovation can include
Every project starts with an assessment — you only pay for the scope your crawlspace actually needs.
Vapor barrier
A heavy-mil liner across the crawlspace floor and up the piers/walls, sealed at every seam and penetration.
Full encapsulation
Vapor barrier plus sealed vents and access door — the crawlspace becomes a conditioned, sealed space instead of an open vent to the outside.
Dehumidification
A dedicated crawlspace dehumidifier sized to the square footage, draining automatically, holding humidity in a safe range year-round.
Drainage & sump
Interior perimeter drain and a sump pump for crawlspaces that take on water — routes it out before it ever reaches the vapor barrier.
Structural repair
Sistering or replacing damaged joists and sills, and jacking/shimming to level sagging framing before anything gets sealed up.
Fungus & insulation
Antimicrobial treatment for existing mold/fungus on wood, then new insulation appropriate for a sealed, conditioned crawlspace.
Symptoms upstairs
The crawlspace is out of sight, so most people notice it from the living room first.
- •Musty smell upstairs, even with the windows shut
- •Buckling hardwood, or floors that feel soft underfoot
- •Summer energy bills that seem too high for the house
- •Doors and windows that stick more in humid weather
Four days, typically
Scope and access change the schedule — the assessment gives you a real date range for your crawlspace.
Assessment
Full crawlspace inspection — moisture readings, structural check, existing insulation and vapor barrier condition, and a scope written up with photos.
Clear out & repair
Old insulation and debris removed, any structural repair or fungus treatment done first — nothing gets sealed over a problem.
Seal & equip
Vapor barrier installed and sealed, vents closed, dehumidifier (and sump/drainage if scoped) installed and running.
Verify & hand over
Final moisture readings, a walkthrough of the finished space, photos for your records, and the workmanship warranty paperwork.
Rentals, historic buildings and churches
Crawlspace work on tenant-occupied and historic properties, scheduled around leases and events, with photo documentation per unit for owners, lenders and insurers.
