Office Buildouts in Fairfax, VA
Leasing teams promise incoming tenants a delivery date, and the buildout contractor has to hit it. TopKey delivers office buildouts, tenant fit-outs, whitebox spaces, spec suites, and commercial interior renovations for landlords, property managers, and tenants, with the permitting, scheduling, and trade coordination handled by one accountable team.
We coordinate framing, drywall, doors, glass, flooring, paint, lighting, and the mechanical, electrical, plumbing, and fire protection trades under one schedule and one project manager.

The company was efficient clean, and very easy to work with. The work was done in a timely fashion. I would highly recommend them.”
“St. John's School in Clinton, MD has used TopKey for the past 3 summers for major construction projects to enhance the safety of our school as well as making it more energy efficient with new windows. From the sales rep to the project manager to the technicians themselves have always been professional and courteous. They are always vigilant of when students are on campus and respect their safety. We would strongly recommend TopKey for any project large or small.”
“Glen, Duane, Nancy and your team did an awesome job on the Columbia Park project. Brought to light some unsafe conditions with one of the electrical panels and repaired. Addressed the hot water heater and fountain wiring issues which were outside of the original scope of work. The overall work performed was outstanding and within the scheduled time-line despite some unforeseen items that arose with the warehouse demo portion. Thank you!”

FAQ
Office Buildouts Questions from Fairfax Property Owners
How long does an office buildout take in Fairfax?
A cosmetic refresh can take a few weeks. A full suite buildout with new walls, restrooms, and systems typically runs two to four months including permitting through Fairfax County Land Development Services (LDS) or City of Fairfax Community Development. We give you a realistic schedule up front.
What is the difference between whitebox and a full fit-out?
A whitebox is a neutral, finished shell: walls, ceiling, lighting, HVAC, and restrooms, ready for a tenant to customize. A full fit-out builds the space to the tenant’s specific plan. We deliver both.
Can you work in a building with other tenants in place?
Yes. Most buildouts are in occupied buildings. We contain dust and noise, schedule disruptive work off-hours, and coordinate with property management daily.
Do you work with tenant improvement allowances?
Yes. We regularly work with landlords and tenants on TI-funded projects and provide the documentation both sides need.
