What Affects Crawl Space Costs in New Hampshire?
New Hampshire's old housing stock and harsh winters drive above-average crawl space costs. Many homes in the state have fieldstone or granite block foundations that are difficult to seal properly. The state's rocky soils make drainage installation challenging and expensive. Southern New Hampshire near the Massachusetts border has higher labor rates due to its proximity to the Boston metro area, while the northern part of the state has fewer contractors available. Deep frost lines and heavy snowfall create significant spring melt moisture issues that test crawl space encapsulation systems.
