How long does it take to finish a basement?

Do you handle permits?

Yes. We pull the permits and schedule inspections with your town — it’s part of the job, not an extra.

My basement gets damp sometimes. Can it still be finished?

Usually, yes — but only after the moisture is dealt with. We find the source first (grading, groundwater, humidity) and fix it before framing. If a basement can’t be made dry, we’ll tell you straight rather than take the job.

Do I need an egress window?

If you’re adding a bedroom to the basement, yes — code requires an egress window or door. We include it in the project plan and handle the cutting and installation.

Will finishing my basement add value to my home?

Finished basements consistently rank among the best home improvements for resale in northern New Jersey. You get the space now and the value later.
