Big finish or one piece of it

Want the whole basement done? That is a full finish (8-14 weeks, $40K-$90K mid-range). Just need the part you are missing? We do a basement bathroom on its own (3-5 weeks), a bedroom with egress (4-6 weeks), a wet bar (2-4 weeks), or a single egress window (1-2 weeks). The wet bar gets the same care as the 1,400-square-foot full finish - the job size never changes the standard.

One company holds every trade

Framing, electrical (subpanel + branch circuits + recessed lighting), plumbing (basement bath / wet bar), drywall, flooring - that is all us, under one roof. The only piece we hand off is the HVAC ductwork extension, to an HVAC contractor we line up and coordinate. You make one call and deal with one company, not a string of subs who each blame the last one.

We deal with the water first

A basement is the one room where water is always the question, so we look at your waterproofing and sump pump before anything else gets framed. And if you want a bedroom down there, the law (IRC R310) requires a way out in a fire - so we cut the foundation, set the egress window, and build the window well as part of the job.

Services in this category

How much of your basement are you finishing?

Maybe it's the whole 1,400 square feet. Maybe it's one egress window so a bedroom passes code. Pick the piece that matches what you need. Each one opens to the typical scope and what the work actually looks like.

Operational Authority

Why does a basement take so many trades to get right?

Because a basement asks for all of them at once: framing, insulation, a new electrical subpanel, plumbing if you add a bath or wet bar, drywall, flooring, finishes - plus an HVAC extension and an egress window for any bedroom. That is more trades than a kitchen, more square footage than a bathroom, and more code than either. It is the remodel where the trades have to hand off cleanly, and holding three of those licenses ourselves is exactly where that gets easier for you.

Why we are asked for basements more than any other remodel: A finished basement is the most square footage you can add for the money in Northern Virginia. Most homes here built since 1990 have a 1,000-2,000 sqft basement sitting empty - rough walls, exposed studs, a bare concrete floor. Turning that into a 4th bedroom, a guest suite, an office, a media room, or rental space costs roughly half what the same square footage would cost as an addition. That is why more homeowners ask us for this than for anything else we do. And here is why it goes smoothly: the job needs framing, electrical, and plumbing inside one window, and we hold the Class B Builder and Master Electrician licenses plus licensed plumbing in-house - founder Brad Anson, trained in the Shreve/McGonegal lineage, set the standard the whole team works to. One company, one schedule, on 20+ years of work. No six-week wait on a plumbing sub before the drywall can close.
NEC 250.32 · Subpanel Grounding

Framing then electrical + plumbing rough-in then drywall

Standard sequence: framing complete (perimeter walls + interior walls), then electrical and plumbing rough-in the same week, then inspection, then drywall + insulation + finishes. At Anson, electrical and plumbing rough-in are us - we sequence ourselves. Subpanel installed (60A or 100A) per NEC 250.32 grounding, branch circuits run, recessed lighting boxes set, plumbing drain/vent/supply rough-in for any basement bath or wet bar. Inspection signs off; drywall starts. No waiting on a sub between rough-in and close-up.

VA Code · R-15 to R-19

Moisture-first basement finishing

Basements fail most often from moisture. We assess existing waterproofing + sump pump during the consultation - if either needs upgrading, we surface it before starting the finish. Foundation wall insulation per Virginia code (R-15 to R-19), rim-joist insulation (R-13 to R-19), vapor barriers where appropriate. Wall framing kept off the concrete floor with a pressure-treated bottom plate to break the moisture-wicking path. We don't finish over a moisture problem - we fix it first.

IRC R310 · Emergency Egress

IRC R310 for any basement bedroom

Basement bedrooms require code-compliant egress under IRC R310 - emergency escape/rescue opening: minimum 5.7 sqft, 24-inch clear height, 20-inch clear width, sill height 44 inches or less from the floor, window well with permanent ladder if the sill is below grade. Boman Kemp egress window wells are our standard. Foundation wall cutting, window framing, window well install - all coordinated under one scope. We pull the building permit and pass inspection for egress on every basement bedroom we build.

NEC 210 · Permits + Contract

Building + electrical + plumbing permits

Full basement finishes typically require all three permits: building (for framing + egress + structural changes), electrical (for subpanel + branch circuits per NEC 210), plumbing (if basement bath / wet bar). We pull all three. Permit lead time in NoVA: 1-4 weeks. One contract with a schedule of values: deposit + framing complete + rough-in complete + drywall complete + flooring complete + final. 5-10% contingency for unknown-until-demo conditions (foundation moisture, existing wiring, joist routing surprises). If the contingency isn't used, you don't pay it.

How we work

What finishing your basement actually looks like

It runs in the same four steps as every remodel we do, just stretched out for the longer run of trades a basement needs. A full finish is usually 8-14 weeks on-site. Before that, there's a permit and design stretch of 3-5 weeks. You won't see it at the house, but it counts in your timeline.

01

Free consultation

60-90 minutes. We walk the basement, assess existing waterproofing + sump pump + ceiling height + utility routing, and talk through what you want (open-plan vs. multi-room, bedroom + egress requirements, bathroom / wet bar, flooring tier). No high-pressure design pitches.

02

Written proposal + schedule of values

Itemized: demo (if any), framing, insulation, electrical subpanel + branch circuits, plumbing rough-in (if bath/wet bar), HVAC coordination, drywall, flooring, finishes, 5-10% contingency. Within 5-7 business days of consultation (longer than kitchens/baths because of design depth).

03

Permit, framing, rough-in, drywall, finish

Pull building + electrical + plumbing permits. Framing first (1-2 weeks). Electrical + plumbing rough-in (same crew, 1 week). Inspection. Insulation + drywall + flooring + finishes. Egress install scheduled around foundation cutting (if bedroom). Weekly photo updates.

04

Inspection + punch list + walkthrough

All permitted inspections signed off. We walk through with you, build a punch list together, and address every item before final payment. Subpanel directory labeled. Manufacturer warranties on flooring + fixtures handed over. Inspection card for egress (if applicable).

FAQ

Questions homeowners ask about basement finishing

What does a basement finish cost in Northern Virginia?

Typical full basement finish: $40K-$90K mid-range, $90K-$150K+ for top-tier finishes. Costs scale with basement square footage (most NoVA basements are 1,000-2,000 sqft), inclusion of a bathroom (+$15K-$30K), inclusion of a wet bar (+$8K-$20K), inclusion of a bedroom with egress (+$5K-$10K for the egress install), and the flooring + finish tier. We give you a written proposal with a schedule of values during the consultation.

The variables: (1) square footage (rate per sqft is roughly $35-$75 mid-range, $80-$120+ for top-tier finishes), (2) bathroom inclusion (adding plumbing is the single largest cost-jump), (3) wet bar inclusion, (4) bedroom with egress (egress window install + foundation cut), (5) flooring tier (carpet $3-$5/sqft, LVP $5-$10/sqft, engineered hardwood $10-$15+/sqft), (6) ceiling type (drop ceiling cheaper, drywall ceiling costs more). A 1,500-sqft basement with full bath + wet bar + 1 bedroom + LVP flooring runs about $60K-$80K mid-market. Smaller bedroom-only finishes run lower; custom millwork runs higher.

How long does a basement finish take?

Typical full basement finish: 8-14 weeks from demo to walkthrough. Smaller scopes run faster: basement bedroom + egress addition 4-6 weeks, basement bathroom standalone 3-5 weeks, wet bar standalone 2-4 weeks, egress window standalone 1-2 weeks. The permit + design phase adds 3-5 weeks pre-construction before work starts on-site.

The timeline structure: weeks 1-2 framing. Week 3 insulation, electrical + plumbing rough-in, inspection. Weeks 4-5 drywall + paint. Weeks 6-8 flooring + tile + finishes. Weeks 9-12 bathroom buildout (if scoped), wet bar (if scoped), egress install (if scoped), punch-list close. Larger basements with bedroom + bath + wet bar all included run closer to 14 weeks; simpler open-plan main-area-only finishes can run closer to 8 weeks. We give you a written schedule with milestones during the proposal phase.

Do I need to address moisture before finishing the basement?

Yes, almost always. We assess existing waterproofing (foundation seal, exterior drainage) and the sump pump during the consultation. If either is at end of life or has known issues, we address them before framing starts - finishing over a moisture problem ruins finished work within 2-5 years. Sometimes the existing setup is fine; sometimes it needs upgrade. We tell you up front.

The most common moisture issues we see during basement consultations: (1) sump pump at end of life (10+ years old, slowing, or making intermittent noise), (2) sump pump primary without battery backup (catastrophic risk if power fails during a storm), (3) foundation wall cracks letting groundwater seep, (4) inadequate exterior grading (water flowing toward the foundation instead of away), (5) old-style foam-board insulation directly against potentially moisture-prone concrete. For deeper waterproofing work (interior French drain, exterior excavation) we coordinate with a specialist - that is outside our Class B scope. For straightforward upgrades (sump pump replacement, vapor barrier, proper insulation install) we handle it.

Do you handle the egress window cutting and installation, or is that a separate contractor?

We handle it. Cutting the foundation wall for an egress window, installing the window itself, and installing the window well are all part of the basement bedroom scope we deliver. IRC R310 code compliance is on us. Boman Kemp egress window wells are our standard product. We pull the building permit for the egress install and pass inspection.

The egress window install scope: (1) foundation wall cut (typically with a concrete saw) - this is the work that scares most homeowners; we have done enough that we know which foundations cut cleanly and which need extra structural review, (2) header installation above the new opening for structural support, (3) egress window installation (typically vinyl or fiberglass casement), (4) window well install (Boman Kemp) with a permanent ladder if the sill is below grade, (5) exterior grading + drainage around the well. Most egress installs complete in 2-3 days as part of a larger basement project.

Does my basement bedroom need an egress window even if it is already there?

If it is a bedroom (legally defined: a room where someone sleeps), yes - IRC R310 requires egress for all bedrooms. A finished basement with a room that has a closet and is being used as a bedroom but does not have egress is a code violation and a real-estate-sale liability. Many NoVA basements have office spaces or exercise rooms that are actually being used as bedrooms without legal egress.

The practical test: (1) does the room have a closet or could it be used as a bedroom? (2) is it being used for sleeping? If both yes, egress is required. At sale, a home inspector or appraiser will flag a basement bedroom without egress - typical resolution is either (a) install egress (about $4K-$8K standalone), (b) reclassify the room as a non-bedroom (no closet, no sleeping use), or (c) accept the price reduction from the buyer. We do all three depending on the homeowner plan, but installing the egress is the only path that preserves the room value long-term.
