What Affects Crawl Space Costs in Maryland?
Maryland's diverse geography ranges from the Chesapeake Bay coastal plain to the Appalachian Mountains, each presenting different crawl space challenges. The DC suburbs in Montgomery and Prince George's counties have some of the highest labor rates in the mid-Atlantic region. Bay area homes face high humidity and periodic tidal flooding, while western Maryland homes deal with cold-weather moisture issues. The state's clay soils in the Piedmont region are particularly problematic for foundation moisture. Maryland's strict building codes add to project costs but ensure quality workmanship.
