What Affects Crawl Space Costs in Maine?
Maine's harsh winters and old housing stock create unique crawl space challenges. Many homes date to the 1800s and early 1900s with fieldstone foundations that allow significant moisture and cold air infiltration. The deep frost line (60+ inches in northern Maine) requires substantial insulation in crawl spaces to prevent frozen pipes. Coastal areas face salt air corrosion and nor'easter-driven moisture. Labor costs are above the national average due to the skilled nature of the work and relatively small contractor pool in rural areas.
