910 Crawl Space Pros provides crawl space cleanup across Wilmington and the Cape Fear region. Crawl space cleanup is the removal of everything that should not be under the house — fallen insulation, construction debris, torn plastic, and animal contamination — so that the space can be assessed properly and lined.

What we do on the first visit

Assess what is down there and whether any of it is a contamination issue requiring different handling. Rodent droppings and standing water change the scope and the protective equipment needed.

What comes out of a typical Wilmington crawl space

Fallen fiberglass batts are the most common single item, usually wet and usually holding a nest. After that: offcuts and packaging left by the original builder, previous torn liner, ductwork insulation that has failed, and in older homes decades of accumulated material from prior trades.

None of it can stay. Debris under a new liner is a puncture risk, wet insulation is a moisture reservoir, and animal contamination is a health question that a sheet of plastic does not resolve.

Rodent contamination needs different handling

Droppings and nesting material are not ordinary debris. Disturbing them dry aerosolises whatever is in them, which is why the work is done with appropriate respiratory protection and the material is wetted before removal rather than swept.

Where contamination is significant, removal is followed by treatment of the affected surfaces, and by sealing the entry points — otherwise the animals return to a cleaner space.

What's included

  • Full removal of debris, fallen insulation and failed liner
  • Bagged removal and disposal, not relocation to another part of the crawl space
  • Appropriate handling and PPE where animal contamination is present
  • Treatment of contaminated surfaces after removal
  • Identification of entry points where animals have been getting in
  • Ground raked level so the new liner sits without puncture risk
  • Photographs of the cleared space
  • Assessment notes on anything uncovered during clearance

DIY, cheap quote, or done properly

Most of the price difference between quotes is not labour — it is which of these steps the quote silently leaves out.

DIY Cheapest quote Done properly
Liner 6 mil builder sheet, laid loose 6–8 mil, taped seams, not fastened to walls Reinforced 12–20 mil to ASTM E1745, sealed to piers and walls
Groundwater Not addressed Sealed over — water ends up under the plastic Drainage and sump first, liner second
Humidity control None, or a household dehumidifier on an extension cord Undersized unit, condensate draining to the soil Unit sized to cubic footage, pumped to a proper discharge
Vents Left open, or foam blocks pushed in Covered, not sealed Sealed and detailed so the space is genuinely closed
Wood already affected Bleach from a spray bottle Surface treated, moisture source left in place Growth removed, framing treated, dried, then sealed
What it costs $300 – $900 in materials $1,500 – $3,000 $4,200 – $14,000
How long it holds A season or two Often fails within a few years Liner life measured in decades when water is handled first

Crawl Space Cleanup questions

How much does crawl space cleanup cost?
Typically $400–$1,500 for ordinary debris and fallen insulation. Animal contamination raises it because the handling, protective equipment and disposal are different. Access and clearance drive the labour more than volume does.
Can I clean out my own crawl space?
Ordinary debris, yes, with care and a respirator. Rodent contamination is where it stops being a DIY job — disturbing droppings dry is the specific thing to avoid, and doing it properly needs equipment most homeowners do not have.
Do I need cleanup before encapsulation?
Always. Debris under a liner punctures it, and wet insulation left in place continues to hold moisture inside a space you have just sealed. Cleanup is the first line on any honest encapsulation quote.
What happens to the old insulation?
It is bagged and disposed of. Wet fiberglass has no salvage value and reinstalling it would put the same moisture reservoir back into the space.
