New paver and stone patios
EP Henry, Belgard and Unilock pavers, plus bluestone, flagstone and travertine. Excavated to depth, compacted in lifts, and finished with edge restraints and polymeric joint sand.

A patio is only as good as what is under it. We excavate, build a compacted gravel base and set edge restraints, so the surface is still flat and level after years of Maryland freeze and thaw.
Rockville has a wide mix of housing ages, from post-war homes with original decks to new builds where homeowners want a hardscape that matches the architecture.
Most patio failures are drainage and base problems that show up at the surface first.
Standing water means the grading or the base pitch is wrong, and it will keep working the pavers loose.
Usually a base that was too thin or missing edge restraint, not a problem with the stone itself.
Freeze-thaw movement lifts sections that were not excavated below the frost line.
We can re-sand with polymeric joint sand and restore the surface instead of replacing the patio.
Adding features later means cutting into the base. Designing them in now costs far less.
Hardscape, softscape edges and drainage handled by one crew, so nothing gets left for the landscaper to finish.

EP Henry, Belgard and Unilock pavers, plus bluestone, flagstone and travertine. Excavated to depth, compacted in lifts, and finished with edge restraints and polymeric joint sand.

Wood-burning or gas fire features, curved seat walls and built-in lighting, all set into the base during the build rather than cut in afterward.

Segmental block and natural stone walls engineered for the height and the soil they are holding back, with drainage behind the wall where it is needed.

Relaying sunken sections, replacing failed base, resetting edge restraint and re-sanding joints to bring an older patio back without a full replacement.

We work within community guidelines on materials, colors and setbacks, and submit for approval first.
Our new travertine pool deck is absolutely stunning. J&J designed the layout to flow naturally around the pool shape and the drainage has been perfect all summer. Worth every penny.
J&J Pro Build built our composite deck and pergola in Columbia and I could not be more impressed. The crew was professional, on time, and the quality is outstanding. They handled everything, permits, inspections, cleanup. Highly recommend.
We had them install a cedar privacy fence around our entire property in Ellicott City. Fast, clean work, perfectly straight lines, and they were very knowledgeable about HOA requirements. Will use them again for our patio project.
The City of Rockville issues its own permits rather than deferring to Montgomery County, and the application process is its own step we handle for you. We prepare and submit the application and meet the inspector on site, so you are not the one chasing paperwork.
Tell us what you are planning and we will come out, measure, walk through the options and give you a written price. No obligation, and no pressure to sign on the spot.
We also build for homeowners in the neighboring towns below, and everywhere in between.
