Flooring, paint, drywall, trim, siding and the punch-list work that finishes a home right: one licensed contractor and a 2-year warranty on all of it.
Flooring, paint, drywall, trim and the punch-list work most contractors won't touch, done by the same licensed crew that builds full basements. One point of contact from the first walkthrough to the last coat of paint.
Garages, room additions and interior reconfigurations are engineered, permitted builds, and they have their own page. If the square footage itself is the problem, start there.
One free written estimate covers the whole list. Licensed & insured, A+ BBB rating, 2-year workmanship warranty.
