Moisture First

We waterproof before we finish

Drywall over a damp foundation wall is the most common basement mistake in the region. Every project starts with a moisture assessment — grading, gutters, downspouts, foundation cracks, humidity, and sump condition. If waterproofing or drainage work is needed, it goes in first and it's priced in writing before finish work begins. That order is not negotiable, because it's the difference between a basement that lasts and one that molds.

Good / Better / Best

Three ways to finish it — typical ranges

Every tier includes permits, inspections, insulation, drywall, flooring, lighting, and paint. Electrical, plumbing, and HVAC work is performed by licensed trade partners. All figures are typical ranges confirmed in your free consultation.

Good — Open rec room

$32,000–$48,000

The classic family-space finish: one open room done properly.

  • Framing, insulation & drywall throughout
  • LVP flooring & recessed lighting
  • Code outlets & switches by licensed trade partners
  • Paint, trim, and finished stairs
  • Permits & final inspection included

Better — Bedroom & full bath

$48,000–$70,000

Everything in Good, plus a legal bedroom and a full bathroom.

  • Code-compliant egress window or door
  • Full bath — shower, vanity, tile, exhaust
  • Plumbing & venting by licensed trade partners
  • Closet build-out so the bedroom counts on appraisal
  • Separate HVAC supply/return by licensed trade partners

Best — Full suite + wet bar

$70,000–$100,000

A complete lower level: guest suite, entertaining space, storage.

  • Bedroom, full bath & egress as in Better
  • Wet bar — cabinetry, counter, sink & beverage fridge rough-in
  • Upgraded finishes: tile, feature walls, under-cabinet lighting
  • Laundry or kitchenette rough-in by licensed trade partners
  • Sound insulation & upgraded doors

Egress & Permits

What makes a basement bedroom legal

Egress is the law

Any basement bedroom in Maryland or Virginia needs a code-compliant emergency escape — an egress window or door of the required opening size, with a window well where needed. We cut, waterproof, and finish egress openings as part of the project, so the bedroom is legal square footage, not just a room with a bed in it.

Permits & inspections, handled

Finishing a basement requires building permits in both states, plus trade inspections for electrical, plumbing, and HVAC — all performed by licensed trade partners under permit. United Developers files the paperwork, meets the inspectors, and hands you the approved records at closeout.

Why legal matters at resale

Unpermitted basement work is a standard red flag on appraisal and home inspection. Permitted, inspected finished space counts toward your home's finished square footage — which is exactly where the value of this project comes from.

How It Works

From damp storage to finished suite

1

Consultation & moisture assessment

We measure the space, check headroom and egress feasibility, and run the moisture assessment. You get written Good/Better/Best ranges against your actual floor plan — plus a $0-down financing illustration.

Free · In writing
2

Waterproofing & prep (if needed)

Drainage, sealing, sump work, or crack repair goes in before any framing. If your basement is already dry, this step is a written confirmation that it is.

Dry before drywall
3

Permits & design lock

Layout finalized, selections made, permits filed with your county. Egress openings are engineered into the plan here.

1–4 weeks, county-dependent
4

Build-out

Framing, rough-ins by licensed trade partners, inspections, insulation, drywall, flooring, tile, trim, and paint — typically 4–6 weeks for a rec room, 6–9 for bedroom & bath, 8–12 for a full suite.

One accountable crew
5

Final inspection & walkthrough

County final inspection, a room-by-room walkthrough with you, and your warranty — 2-year workmanship, in writing — plus the full permit record.

In writing

Financing: $0-down plans from 12 to 180 months on approved credit, quoted alongside your consultation number — so you see the monthly payment next to the project price, not after it.

Common Questions

Straight answers

What does it cost to finish a basement in Maryland or Virginia?

Typical ranges: $32,000–$48,000 for an open rec room, $48,000–$70,000 to add a legal bedroom and full bath, and $70,000–$100,000 for a full suite with wet bar. These are typical ranges, not quotes — your exact number is confirmed in a free consultation, and $0-down financing from 12 to 180 months is available on approved credit.

Do I need a permit to finish my basement?

Yes — in both Maryland and Virginia, finishing a basement requires building permits, and adding a bedroom requires code-compliant egress. We pull the permits, schedule the inspections, and build egress to code so the space counts as legal finished square footage.

What if my basement has moisture or past water issues?

We address moisture before finishing — always. The consultation checks grading, gutters, downspouts, foundation cracks, and humidity. If waterproofing, drainage, or a sump system is needed, it goes in first, because drywall over a damp wall is money thrown away.

How long does basement finishing take?

Once permits are in hand, a rec-room finish typically runs 4–6 weeks, a bedroom-and-bath build-out 6–9 weeks, and a full suite with wet bar 8–12 weeks, depending on scope and inspection scheduling.

Who does the electrical and plumbing work?

All electrical, plumbing, and HVAC work is performed by licensed trade partners and inspected under the permit — every circuit, drain line, and duct in your finished basement is code-compliant and documented.

Dry first. Legal always. One number in writing.
