DONE RIGHT BELOW GRADE
What goes into a Great House basement
A basement has to handle moisture, cold and code rules a main floor never sees. Here is what a full finish includes.
01
Moisture check first
We look for leaks, grading and sump issues and fix them before any wall goes up.
02
Insulated framing
Insulated exterior walls and moisture-resistant framing keep the space warm and dry.
03
Egress & safety
Code-compliant egress windows for bedrooms, plus smoke and CO detectors.
04
Electrical & lighting
New circuits, recessed lighting and outlets where you will actually use them.
05
HVAC & comfort
Heating and cooling extended so the lower level feels like the rest of the house.
06
Basement-ready flooring
Waterproof LVP or tile that handles humidity without warping.
07
Bathroom or wet bar
Full baths, half baths and wet bars, with below-grade plumbing done to code.
08
Permits & inspections
Building, electrical and plumbing permits filed and inspected, start to finish.
Plus our 1-year workmanship warranty on every basement.

FAQ
Basement questions, answered
How much does it cost to finish a basement in McLean and Northern Virginia?
A full basement finish usually runs $35,000–$65,000. Adding a bathroom, wet bar or guest suite brings it to $65,000–$100,000+. Refreshing an already-finished basement starts around $15,000. You get an exact, itemized price after a free walk-through.
Is finishing a basement worth it?
Usually, yes. It is one of the most affordable ways to add living space, because the foundation, walls and roof already exist.
Do I need a permit to finish my basement in Fairfax County?
Yes, in most cases. Finishing a basement typically needs building, electrical and, if you add a bathroom, plumbing permits. We handle them.
Can I add a bedroom in the basement?
Yes, if it has a code-compliant egress window or door. We can cut and install an egress window as part of the project.
How much does an egress window cost?
Most basement egress windows run about $5,000–$10,000 installed, depending on the foundation, digging and window well. Bedrooms need one to be legal.
Can you finish a basement with low ceilings?
Often, yes. We work around ducts and beams with soffits, use slim lighting and plan the layout so the main living areas get the most height.
How long does a basement finish take?
Construction usually takes 4–8 weeks. With design and permitting, plan on about 2–3 months from first visit to finished basement.
What about water and moisture?
We check for moisture first and fix leaks, grading or sump issues before finishing. Then we use insulated, moisture-resistant materials and waterproof flooring.
Are you licensed and insured?
Yes. The Great House LLC holds Virginia Class A contractor license #2705197237, is fully insured, and every job includes a 1-year workmanship warranty.
