Berwick basement finishing — local context
Finishing a Berwick basement means building to the Maine Uniform Building and Energy Code, which adopts the 2021 International Residential Code (Maine Office of State Fire Marshal). Under IRC R310, any habitable basement — especially a new bedroom — needs an emergency escape opening of at least 5.7 square feet, minimum 24 inches high, 20 inches wide, with the sill no more than 44 inches off the floor. MUBEC is mandatory here, since it applies in municipalities of 4,000-plus residents and Berwick's population is 8,175 (U.S. Census ACS). Your permit comes from the Town of Berwick Code Enforcement office at 11 Sullivan Street; the town's 2026 application states no permit issues the day you apply — allow 10 business days for review. 603 pulls that building permit for you. Most finishes run 4–24 weeks. Basement finishing runs $30,000–$200,000; an egress window install is $8,000–$15,000. See our basement finishing work and egress window installation.
What a recent customer said
I worked directly with the owner chris pagliccia and I couldnt be happier with my experience. They completed multiple projects for us including a basement demo, floor leveling, support beams, and lastly finishing turning the unfinished basement into an inlaw apartment. The project in its entirety took 6 months but throughout the entire thing they communicated well and we didn't spring on us a single "Surprise bill". Great company.
