Class A licensed and bonded contractor serving Fairfax, Northern Virginia

An unfinished basement is one of the highest-return investments a homeowner in Northern Virginia can make. If you are searching for basement remodeling in Fairfax, VA, SB Builders and Construction Inc. is the Class A licensed contractor your neighbors have trusted since 1998. We transform raw, unfinished, or outdated lower levels into fully finished living spaces, home offices, in-law suites, media rooms, and income-generating rental units. Our team handles every phase in-house, from framing and electrical rough-in through drywall, flooring, lighting, and final trim, with zero subcontracting and zero surprises on the final invoice.

What a Finished Basement Adds to Your Home
in Northern Virginia

A professionally finished basement does more than create extra square footage. It directly increases your home's appraised value, expands your usable living space, and gives your household functionality that the rest of the house cannot provide.

Real Value, Real Returns for
Fairfax Homeowners

In Northern Virginia's competitive real estate market, finished square footage translates directly into sale price. Homeowners in Fairfax, McLean, and Arlington consistently recoup a significant portion of basement finishing costs when they sell, and many see appraisal values rise well above project cost when the work is done to a high standard. Beyond resale, a finished basement eliminates the dead storage zone that drags down your daily life and replaces it with space your family actually uses. Whether that means a dedicated home office that earns you back hours in productivity, a bedroom suite for aging parents, or a rec room that keeps kids off the main living level, the return is both financial and practical. 
SB Builders has completed basement renovations across Fairfax County, Arlington, and Northern Virginia for over 25 years. We know which ceiling heights work for habitable space under Fairfax County code, how to handle the moisture and drainage challenges that basements in this region commonly present, and how to route HVAC, plumbing, and electrical through tight spaces without compromising the structural integrity of the floor above. That local, hands-on knowledge is what separates a finished basement that lasts from one that fails inspection or develops problems within a few years.

Basement Uses That Northern Virginia Families Actually Build

The most popular finished basement configurations we build in Fairfax and the surrounding area include home offices and remote work suites with dedicated lighting and data infrastructure, bedroom additions with egress windows that meet Virginia code requirements, full bathroom remodeling additions that make the lower level fully self-contained, media and entertainment rooms with acoustic insulation and custom lighting, in-law or au pair suites with kitchenette setups, and rental units for homeowners who want to generate income from existing space. Every project starts with a conversation about how you actually want to use the space, not a generic floor plan pulled from a template.

How SB Builders Approaches Basement Renovation Projects

Every basement finishing project in Northern Virginia involves site-specific conditions that a generic process cannot account for. Moisture levels, ceiling height, existing mechanical systems, soil type, and local permit requirements all affect how a project is designed and built. SB Builders uses a structured, phase-by-phase approach that addresses these factors upfront so there are no surprises mid-project.

Assessment, Design, and Permitting

Before any framing begins, our team conducts a full site assessment of your basement. We check for active moisture intrusion, test ceiling clearance against Fairfax County habitable space requirements, identify load-bearing elements that affect wall placement, and assess the current state of your electrical panel and HVAC capacity. If your project requires a plumbing rough-in for a bathroom addition, we plan the drain line routing before framing locks anything in place. This pre-construction phase is where most basement problems get caught and solved on paper rather than discovered mid-build. We handle all permit applications with Fairfax County on your behalf. Finished basement space in Virginia requires permits for framing, electrical, plumbing where applicable, and HVAC work. We prepare the documentation, submit the applications, coordinate inspections at each phase, and deliver a fully permitted, inspection-passed finished space. You do not need to track the process or appear at the county building department. If your project also involves framing and structural work beyond the basement scope, we coordinate that under the same contract and permitting package.

Construction, Finishes, and Final Walkthrough

Once permits are approved, construction moves through a defined sequence. Framing and rough mechanical work happen first, followed by insulation, drywall, and then finish work including flooring, trim, doors, lighting fixtures, and any custom cabinetry or built-ins. We use our own in-house team for every trade, which means scheduling is coordinated internally and your project does not sit idle waiting for an independent subcontractor to show up. At the end of every project, we walk the finished space with you, address any items on your punch list before we close out, and confirm that all inspections have been finalized and passed. The space is yours clean, complete, and fully signed off.

Basement Remodeling Costs and Financing in Fairfax, VA

Cost is the first question most homeowners ask, and it is also the question most contractors answer vaguely to avoid commitment. SB Builders gives you a detailed written estimate before any work begins so you know exactly what you are paying for.

What Determines the Price of a Basement Finish in Northern Virginia

Basement finishing costs in the Fairfax, VA area depend on several factors: the square footage being finished, the ceiling height and whether any structural modifications are needed, the number of rooms and their function (a simple open plan costs less than a suite with a bathroom and kitchenette), the finishes selected for flooring, lighting, and trim, and whether existing mechanical systems need upgrading to serve the new space. As a general reference, basic open-plan basement finishing in Northern Virginia typically starts at a lower cost per square foot, while full-suite configurations with bathroom remodeling, kitchen or wet bar work, and premium finishes occupy a higher range. The only way to know what your specific project will cost is a site visit and a written estimate. We provide that at no charge.

Bob, the project manager, was very patient with me as a first time renovator. I asked approximately 1m questions and he answered them all. The technicians that actually did the tiling, painting, etc., were efficient, respectful and professional. They finished an entire bathroom renovation in less than a full 2 weeks! Excellent company!

We did a full bathroom remodel and Bob was great to work with throughout. He was easy to reach and always kept us updated on what was happening next. The team showed up on time and kept the space clean. The tile work and fixtures look great and everything was done properly.

I couldn’t be happier with the work SB Builders did on our bathroom renovation. From the very beginning, Bob was fantastic. I reached out to him with some challenging issues with my walls and floors, and he took the time to carefully listen and then offered multiple practical solutions. He never pushed us toward the most expensive option—just honest, smart recommendations that fit our needs and budget.
Once we decided on the scope of work, his installers arrived right on time and got straight to it. The quality of the work was outstanding—everything was done meticulously right the first time. All surfaces were square and flat, and the entire job was left spotless and clean. Best of all, there were no hidden fees, no surprise upcharges, and no unnecessary extras. Just honest, high-quality work at the price we agreed on.
My wife and I could not be happier with the final result. SB Builders exceeded our expectations in every way. We will definitely be using them again for future projects and will be recommending them to everyone we know.
Wow! SB Builders did another job for us, this time two remaining bathroom renovations, and both turned out extremely well. We chose the materials they used, and they got the sundries of construction and did the work. I trust Bob and his team to do excellent work. They have not let me down. We used them for a main bedroom/bath suite creation and were so happy with the results that not only have we brought them back for this renovation, but we’ve recommended him to several friends, ALL of whom have used his services.

The team is responsive, friendly, on time, diligent, and do great work. They listened when I had special requests and made changes to accommodate, doing it happily.

Have I mentioned how quickly they did the work? Essentially, just under three weeks. That includes demolition, buildout and finishing, and a final clean up from a cleaning company. The only delays were on our side because of fixture shipping delays, and they worked around it.

Bob is the owner and he’s responsive, knows his business, and is happy to work with clients to make their projects just right.

And finally, let me say that SB Builders is very competitively priced. Not only do you get quality work, you get it at great prices.

Just look at the finished projects! I could not be happier.

We worked with Bob and his team to complete a fairly complex kitchen remodel, which turned out beautifully and has completely transformed our home. The project included removing the existing wall between the dining room and kitchen, removing another wall in the entryway, replacing a sliding glass door with a single door, replacing two small windows with a large window, and building an entirely new kitchen within that new space. We stripped the kitchen down to subfloor and studs and entirely changed the layout of our kitchen to better optimize the space and create a new open feeling throughout the 1st floor. We also installed new hardwood throughout the first floor to create a seamless look. We're very happy with the results that we achieved with SB Builders. Bob is great to work with and he's very focused on delivering high quality work on a fast timeline. Cycling crews through the job is one of Bob's superpowers - he will work tirelessly to keep a steady flow of progress on the job. Bob proved to be a very knowledgeable and flexible partner on this project. There were several unknowns at the start (especially regarding taking down the walls) and I made several revisions during the job. Bob's change orders were very fair and ultimately I feel that we got a good value for the work that was performed. I would definitely recommend working with Bob for kitchen remodeling projects. He's a great guy and very focused on providing an honest value to the customer, which I greatly appreciated throughout the project.

We couldn’t be happier with our experience working with Bob and his team!! He just finished a full hair salon build out for me and my partner and he has blown us away. His communication and follow-through are truly unmatched — he is efficient, kind, and incredibly reliable. Any time we needed something done, he delivered. His crew is professional, pleasant to be around, and clearly cares about the quality of their work.

Bob always answers the phone (I’m convinced he doesn’t sleep!) and consistently goes above and beyond to make sure everything is done right. If you’re looking for a contractor who truly shows up, communicates, and delivers excellent work, Bob is the one. Highly recommend!

We engaged SB Builders and Construction to add an addition to our home. We needed a mother-in-law's suite on the first floor as well as a second floor addition to expand our master bedroom and on-suite. Bob and his team were consummate professionals from start to finish. Bob walked us through every step of the process from design to final completion. Bob is an exceptional contractor with extreme detail to customer service. He is available 24/7, always promptly answers emails and text messages and is always available to answer questions. Bob also is on site daily checking on the build and making sure things are going according to schedule. Bob's team is also is exceptional. Edwin, his project manager, is second to none. He knows how to construct just about anything and when an issue occurs he knows how to fix it. During construction our daughter asked "is Edwin coming today" because she knew he would do quality work. We bought the workers lunch on more than occasion because they were so professional. Overall, we are extremely happy with the workmanship we received and the attention to detail that SB Builders provided. I will not hesitate to recommend them to anyone. Our project was finished on time and with exceptional results!
Basement Remodeling FAQ

Frequently Asked Questions
About Basement Remodeling

Planning a basement renovation in Fairfax County? Here are answers to the questions homeowners ask most before turning an unfinished basement into valuable, comfortable living space.

01 How much does basement remodeling cost in Fairfax, VA?

Basement finishing in Fairfax, VA typically ranges from $30 to $75 per square foot depending on the scope, finishes, and whether plumbing is involved. A basic open-plan finish on a 600-square-foot basement often falls in the $20,000 to $35,000 range, while a full suite with a bathroom and bedroom can reach $50,000 to $80,000 or more. SB Builders provides free detailed estimates so you know the exact cost before committing.

02 How long does a basement remodel take?

Most basement finishing projects with SB Builders take between four and eight weeks from permit approval to final walkthrough. A straightforward open-plan finish on a clean, dry basement moves faster. Projects that include plumbing rough-in for a bathroom, egress window installation, or significant structural modifications take longer. We provide a written timeline before work begins and communicate any changes in advance.

03 Do I need permits for basement remodeling in Fairfax, VA?

Yes. Finished basement space in Fairfax County requires building permits covering framing, electrical, and plumbing where applicable. SB Builders handles all permit applications and inspection coordination with Fairfax County on your behalf. You do not need to manage this process yourself. Working without permits can create serious problems at resale and may affect insurance coverage for the finished space.

04 Can any basement be finished?

Most basements can be finished, but site conditions matter. Minimum ceiling height for habitable space in Virginia is typically seven feet, though some configurations are possible at lower heights. Active moisture intrusion must be resolved before framing. Existing mechanical systems must have adequate capacity to serve the new space. Our pre-construction assessment identifies potential issues before work begins so there are no unnecessary mid-project surprises.

05 Will a finished basement increase my home's value?

Yes, in many cases. Finished basement square footage can add to a home's market appeal and value in Northern Virginia. The return on investment depends on the quality of the finish, whether the space meets code as habitable area, and local market conditions. A properly permitted, high-quality basement renovation in Fairfax County can provide meaningful value while improving the home's usable living space.

06 Does SB Builders handle basement moisture or waterproofing issues?

SB Builders assesses moisture conditions as part of every pre-construction evaluation. If active water intrusion is present, we identify the source and the remediation required before any finishing work begins. Finishing over an unresolved moisture problem can lead to mold, structural damage, and failed inspections, so we do not take shortcuts that could harm your home or create liability. If the scope requires foundation work or exterior drainage solutions, we can handle that under the same project or coordinate it as a prerequisite phase.

07 Do you offer financing for basement remodeling?

Yes. SB Builders offers flexible financing for basement renovation projects of any size, including for clients across a range of credit scores. Ask about financing when you request your free estimate. You can reach us by phone at 703-625-0132 or through the contact form on our website .

08 What other services can be added to a basement remodeling project?

Basement projects frequently include bathroom additions , framing and structural modifications , windows and exterior improvements such as egress window installation, and general construction work like electrical panel upgrades and HVAC extensions. SB Builders manages this work under a single contract so you have one team, one timeline, and one point of accountability.
