A finished basement is one of the highest-ROI renovations a Massachusetts homeowner can make — adding 30–50% of cost back at resale and dramatically expanding livable space. Schlickmann Construction handles every step, from waterproofing to drywall, framing to flooring, electrical to lighting.

Massachusetts basements have unique challenges: high water tables, fieldstone foundations, low ceilings, and decades of patchwork plumbing and electrical. We start every basement project with a moisture assessment — addressing any seepage with French drains, sump pumps, vapor barriers, or interior dimple membranes before we frame a single wall.

From there we deliver a full living-quality space: framed and insulated walls, recessed LED lighting, dedicated electrical circuits, sound insulation, luxury vinyl or carpeted floors, and finish carpentry to match the rest of your home.

Common Questions About Basement Finishing

Yes. Any basement finishing project in Massachusetts requires a building permit, and bedrooms specifically require an egress window meeting state code (5.7 sq ft, 24" min height, 20" min width, sill height ≤ 44").

We address moisture before finishing — French drains, sump pumps, exterior waterproofing, or interior dimple membranes. We don't frame over a wet basement; we fix the source first, then deliver a 5-year warranty against water in the finished space.

Almost always. We use up-flush toilets (Saniflo) or sewage ejector pumps when the basement is below the main sewer line. Adding a basement bath typically runs $12K–$25K and adds another 4–6 weeks to the project.

Massachusetts code requires 6'8" minimum finished ceiling height in habitable space. We've made many "too low" basements work by removing low-hanging ductwork, re-routing pipes, and using slim LED downlights. We assess ceiling height during the first visit.
