Our Process

How We Finish Your Basement

01

Moisture Assessment

We inspect your basement walls, floor, and drainage before a single stud goes up — no hidden moisture surprises later.

02

Design & Layout

We plan the space to maximize usable square footage, egress compliance, and ceiling height utilization.

03

Framing & Waterproofing

Steel or wood stud walls are framed. Moisture barriers, spray foam insulation, and any drainage systems are installed.

04

Mechanicals & Drywall

Electrical, plumbing, and HVAC rough-ins are completed and inspected. Then drywall, mud, and tape.

05

Flooring, Trim & Finish

LVP, carpet, or tile flooring, painted walls, LED lighting, and all finishes are installed to a polished standard.

The Jhay's Difference

We Start With Moisture. Then We Finish Right.

Too many basement finishing contractors skip the moisture assessment step. We never do. Every basement gets a full evaluation before framing begins — because a beautiful basement built over a moisture problem is a disaster waiting to happen.

  • Moisture inspection before any framing or materials are ordered
  • Waterproofing solutions available (interior, exterior, or both)
  • Closed-cell spray foam insulation for maximum energy efficiency
  • Egress window installation for legal bedroom compliance
  • All permits pulled, all inspections coordinated
  • 1-year labor warranty on all completed work
FAQ

Basement Finishing Questions

Q:How much does basement finishing cost in NJ?

Costs vary widely based on scope, but most basement finishing projects range from $40–$80 per square foot fully finished. We provide detailed, line-item estimates at no charge.

Q:Do I need to waterproof before finishing?

If your basement has any history of moisture, seepage, or leakage — yes, absolutely. We assess every basement before starting. Finishing over a wet basement creates serious mold and structural problems.

Q:Can a basement bedroom be legal in NJ?

Yes, with a proper egress window (minimum 5.7 sq ft opening, 24" high, 20" wide) and a closet. We handle egress window cutting and well installation as part of the project.

Q:How long does basement finishing take?

Most basement finishing projects take 4–8 weeks from permit approval. Larger or more complex projects with wet bars, bathrooms, or home theaters can take 8–12 weeks.
