Can a Crawl Space Be Converted to a Basement?

A crawl space beneath your house can become a beautiful basement large enough for an additional bedroom, home theater or workshop. The crawl space is the underside of your house offering cramped access to plumbing pipes. The area is so compact that service workers usually may slide in on their backs while using flashlights to illuminate the area. Converting the area to a full basement is challenging, and usually requires the services of an experienced, reputable contractor.
  1. Process

    • A designer and structural engineer work together to plan crawl space conversions. The work of the structural engineer is crucial. During the conversion, engineers install temporary supports for the house. This allows workers to cut an entry hole into the crawl space for removal of dirt. Using machinery and shovels, they will remove enough dirt to create a basement up to 12 feet deep, according to one Denver-area contractor specializing in the conversions.

    Completion

    • After digging out a suitable space, workers install structural reinforcements to support the basement. Repairs to the home’s original structural supports are made if necessary. Workers then pour cement for the basement's floors and walls. Another construction crew experienced in home building or remodeling takes over after the conversion. They enter the basement to frame it for bathrooms, bedrooms, laundry areas or recreation space. The final step is interior design work.

    Precautions

    • Extreme care is necessary in choosing a reputable contractor. A botched conversion could lead to structural problems for the entire house. Converting a crawl space after the original construction allows for a possibly cost-effective remodeling. However, homeowners should consult with at least three independent structural engineers for advice and opinion before they contact contractors.

    Due Diligence

    • A final step before signing a contract is to obtain references for the contractor. Ask for telephone numbers of four customers who hired the contractor for converting a crawl space into a basement. Visit at least three of the referrals, if possible, to review the contractor's work and ask questions about the former clients' level of satisfaction with their new basements. Also check with the local chapter of the Better Business Bureau to see if the contractor has any complaints lodged against him.
