What a finished basement includes
- Moisture check first. We look for efflorescence, old water lines, cracks, and grading issues before we frame a single wall.
- Framing and insulation with a thermal break against the foundation, so the walls stay dry and the room stays warm.
- Electrical and lighting, including recessed lights, dedicated circuits for TVs and gym equipment, and smoke and CO detectors.
- Soffits and ceilings built around ducts, beams, and plumbing so the ceiling height works.
- Flooring rated for below-grade use: luxury vinyl plank, engineered floors, or carpet over a subfloor system.
- Permits and inspections pulled by DMF. A permitted basement counts when you sell. An unpermitted one can hold up the sale.
Popular basement layouts
Family room plus a play area. Home office with a door that closes. Guest suite with a bedroom and full bath. Home gym with rubber flooring and mirrors. Media room with a projector wall and a bar. Most projects combine two or three of these.
Why homeowners pick DMF
We're a general contractor, not a basement-system franchise. That means we can move a wall, relocate a mechanical, add a bathroom, or cut in an egress window without handing you off to another company.
Typical cost
Most Union County basement finishing projects run $50,000 to $95,000 for 700 to 1,000 square feet, or roughly $45 to $130 per square foot depending on finish level, bathrooms, and egress windows.

Questions about basement finishing
How long does it take to finish a basement?
Most projects take 5 to 8 weeks of construction once permits are issued. Permits in our towns typically take 2 to 4 weeks.
Do I need a permit to finish my basement in New Jersey?
Yes. Finishing a basement in New Jersey requires a construction permit and inspections for framing, electrical, plumbing, and insulation. DMF handles all of it.
Is my ceiling tall enough?
New Jersey follows the residential code, which generally requires about 7 feet of ceiling height for habitable space, with allowances for beams and ducts. We measure during the estimate and plan soffits so the room meets code.
