Why Choose MRG

Not Just Drywall
and Drop Ceilings.

A lot of basement jobs get rushed — framing goes up fast, moisture issues get buried behind drywall, and the finishes never quite match the rest of the house. We do it differently. Every basement starts with a proper assessment of moisture, drainage, and mechanical systems before a single stud gets nailed in.

Materials & Systems We Use

Quality at Every Level

Waterproofing

Interior Drainage & Sump Systems

French drains, sump pits, and battery backup systems installed correctly — the first line of defense against moisture damage.

Insulation

Closed-Cell Spray Foam & Rigid Board

Moisture-resistant insulation for below-grade walls — more effective than fiberglass batt in a basement environment.

Flooring

LVP, Engineered Hardwood & Tile

Waterproof flooring options designed for below-grade conditions — no buckling, no mold, no maintenance headaches.

Framing

Pressure-Treated & Steel Stud

Moisture-resistant framing at the slab level — the right material in the right location, so walls don't rot from the bottom up.

Ceilings

Drywall & Drop Ceiling Systems

Finished drywall ceilings where height allows; suspended grid systems where access to mechanicals is needed. We recommend what's right for your space.

Electrical

Recessed Lighting & Panel Work

Properly permitted electrical work — recessed cans, dedicated circuits for entertainment systems, and subpanel upgrades when needed.

Mint Realty finished our entire basement in about six weeks — family room, a half bath, and a home office. The quality is night and day compared to quotes we got from other contractors. It genuinely feels like the rest of our house now.

Common Questions

Frequently Asked Questions

A typical basement finishing project runs 6–10 weeks depending on scope. A straightforward open-plan finish is on the shorter end; a full buildout with a bathroom, kitchenette, and custom work takes longer. We'll give you a realistic timeline before work begins.

Yes — and we address it before framing begins. We assess your slab, walls, and drainage at the start of every project. If we find active moisture issues, we address them first. Finishing over a wet basement is one of the most common and expensive mistakes homeowners face.

Yes. Basement finishing projects involving electrical, plumbing, or an egress window typically require a building permit. We handle the application and all required inspections — and we don't skip permits to save time or money.

Yes, but a legal bedroom below grade requires a properly sized egress window — both for code compliance and life safety. We handle egress window installation as part of the project. We'll confirm your ceiling height and window placement meets local requirements during the assessment.

That's the goal. We use the same quality of materials, trim, and finishes throughout — no dropped-ceiling shortcuts or cheap hollow-core doors unless that's what you want. Egress windows, proper insulation, and good lighting go a long way toward making a basement feel like a real part of the home.
