Frequently asked questions
Do I need a permit to finish my basement in New Hampshire?
Almost always. Framing, electrical, plumbing, and egress are inspected by your town. We pull the permits and schedule the inspections as part of the job.
What if my basement gets damp?
We check for moisture and drainage problems first and fix them before we close up any walls, so the finished space stays dry.
Can you add a bathroom in the basement?
Yes. Our licensed plumbers handle the drain work, including an up-flush or ejector system when the basement sits below the main sewer line.
