Crawl spaces in Downtown Charleston
Many older peninsula homes sit on brick piers with low, tight crawl spaces, which makes the work slower and can push quotes up. If a project would change features visible from the street, such as foundation vents on a historic-district home, ask your pro whether City of Charleston Board of Architectural Review approval is needed.
