Susan D.Paver walkway · via Google“I’m extremely happy with my new paver walkway! The workmanship is excellent, and the project turned out even better than I imagined.”
★★★★★
Bob R. — Driveway replacement and front entry steps · March 2026 · via GoogleHad a great experience with Onyx replacing and widening our driveway. They also replaced our front entry steps. John Cash walked us through the process and then kept us informed of the next steps as the actual work was progressing. The crew was very professional and we are very happy with the finished product. Will definitely use again for any future projects.
★★★★★
Nancy P. — Brick, stone or block wall installation · June 2026 · via HomeAdvisorMike and his crew did a terrific job! He gave us a good price on the job, explained everything ahead of time, and carried it out as promised (and even more, throwing in a couple of extras). They arrived on time, completed everything as promised, cleaned up as they went! Mike personally supervised and followed up on each stage. We have absolutely no hesitation in recommending Onyx, and certainly would call on them if we had another project.

Questions
Frequently asked
Do you charge for estimates?
No. Estimates are free across our entire service area. We come out, look at the site, talk through what you are trying to accomplish, and give you a written price with no obligation.
How long has Onyx been in business?
We have been serving homeowners in and around Fairfax since 2010. Onyx is family-operated — you deal with the owners directly, not a salesperson, and the same people who quote the job are on site while it is being built.
What areas do you serve?
Fairfax, Vienna, Falls Church, Arlington, Alexandria, Herndon, Manassas, Manassas Park, and Fredericksburg in Virginia, plus Washington, DC. If you are just outside that list, call and ask — we often can.
How long does a typical project take?
It depends heavily on scope and weather. A front walkway or set of steps is often two to three days. A full driveway replacement usually runs three to five. Larger patios, retaining walls, and multi-part projects take longer, and we give you a realistic schedule with the estimate rather than an optimistic one.
What affects the price of a masonry project?
Square footage, material choice, site access, how much excavation and base work is needed, and any drainage that has to be corrected. Access is the factor homeowners tend to underestimate — a backyard that equipment cannot reach changes the labor considerably. We break all of this out in the estimate so you can see where the money goes.
Do you clean up at the end of each day?
Yes. Job site cleanliness is something we take seriously, and it comes up repeatedly in our reviews. You should be able to use your property while a project is in progress.
Do you handle drainage as part of a project?
Yes, and in most cases we insist on it. Water is the reason most masonry and paving fails early. If your existing drainage is contributing to the problem we are being asked to fix, we will tell you and include the correction in the scope.
