Columbia Crawl Spaces runs the complete under-floor stack: encapsulation from $4,000, moisture control from $1,200, structural repair from $1,500, Class I barriers from $1,500, and clay-side drainage from $2,000 — every scope preceded by a free photographed inspection with readings.
Crawl Space Encapsulation
The engine-off package: Class I seal, closed vents, mechanical drying — 45-55% held through August.
Crawl Space Moisture Control
Dehumidification sized for Midlands air, commissioned on readings, watchable from your phone.
Crawl Space Repair
Jacks, sistered joists, and sill work for framing the condensation years softened.
Vapor Barrier Installation
The ground seal done properly — Class I, wrapped piers, taped seams — not a thin sheet with staples.
Crawl Space Waterproofing
Drainage and sumps for the clay side's storm water — the liquid half of a dry crawl.
Cost Guide: Midlands Prices by Stage
Stage pricing, the clay-vs-sandhills split, and the itemization that keeps every bid honest.
Stages follow readings here
The Midlands splits its ground between clay and sandhills, and honest scoping respects the split: no drainage sold to lots that pass water, no bare-minimum barrier sold to crawls whose readings demand the full engine-off. Sequence stays fixed — liquid before seal, wood before cover, drying always — and lines your inspection numbers didn't order don't appear. It's a short doctrine and the whole company.
Service questions
Which stages will my crawl actually need?
Your ground and your readings decide: sandhills lots usually skip drainage and run seal-plus-dry; clay-side lots add the water stage; framing's condensation ledger sets the repair line. The free photographed inspection reads all three and the scope lists only what your numbers ordered.
Why is everything here organized around one 'engine'?
Because Columbia's crawl problem genuinely is one machine: hot saturated air entering vented crawls and condensing on cooled surfaces, May through October. Every service either shuts the engine off (seal, dry), repairs its output (structure), or handles its liquid accomplice (drainage). One cause, five tools.
Is the inspection really free?
Photographed, measured, itemized, and free across the Midlands — including the verdicts that end in 'your crawl is fine' or 'you only need the barrier.' Readings don't inflate; that's why we lead with them.
