Home Remodeling in Rockville, MD
Kitchens, bathrooms, additions, and ADUs for Rockville, MD homeowners, design, permits, and build under one contract.
Excell Homes has been remodeling homes in Rockville for 20+ years. As the Montgomery County seat, Rockville pairs long-established neighborhoods with a wide range of home styles and eras, and our office in nearby Gaithersburg puts our crews minutes from the job.
That range is the point. A mid-century rambler, a brick colonial, and a newer townhome each ask for a different approach, and a remodeler who only knows one of them is a liability. We fit the design and the build to the home in front of us, whether that means opening up a closed-off kitchen, reworking a tight bathroom, or refreshing a tired exterior.
Every Rockville project runs on the same Montgomery County permitting experience and the same single-contract structure: one team handling design, permits, materials, and construction, one project manager, and one fixed price agreed before the work begins.

Permits & local know-how
Building and permitting in Rockville, MD
Rockville has a permitting quirk worth knowing before you start. It is one of the few Montgomery County municipalities that runs its own permitting: for a home inside the City of Rockville limits, the building permit goes through the city's Department of Community Planning and Development Services, not county DPS. Homes just outside the city line are back under Montgomery County's Department of Permitting Services. We work with both and confirm which one governs your address up front.
Either way, structural work, additions, and electrical, plumbing, or mechanical changes need a permit and inspections. Who issues the plumbing permit depends on whether the address is on City of Rockville water or WSSC water, and the City sends WSSC-water addresses to WSSC for the permit. Knowing which office reviews your plans, and how each one likes them submitted, is exactly the kind of local detail that keeps a Rockville project from stalling in review.
Rockville's mix of eras means cost is driven more by the individual home than by the neighborhood: a 1950s rambler that needs updated systems can cost more to remodel than a newer townhome of the same size. We assess the actual house rather than quoting a generic per-foot number.

Rockville FAQ
Questions from Rockville, MD homeowners
Does Rockville issue its own building permits?
Yes. For homes inside the City of Rockville limits, permits go through the city's own permitting office rather than county DPS. Homes just outside the city are reviewed by Montgomery County. We confirm which office governs your property and handle the submission either way.
Do I need a permit to remodel in Rockville?
For structural changes, additions, or electrical, plumbing, and mechanical work, yes, through either the City of Rockville or Montgomery County depending on your address. Cosmetic updates usually do not. We manage the permitting and inspections as part of the job.
What home styles do you remodel in Rockville?
All of them. Rockville runs from mid-century ramblers and brick colonials to newer townhomes, and each calls for a different approach. We fit the design and construction to the specific home rather than applying a one-size template, which matters most on older houses.
How long does a Rockville remodel take?
Construction time depends on scope, with design and permitting first. Because we prepare complete drawings and know how both the city and county review them, we avoid the resubmissions that stretch timelines and give you a realistic schedule before the contract is signed.
