Deck Builders Near Me in Rockville, MD? Build Your Own Deck With an A-DIY Kit

You have both options. Rockville-area deck contractors can design, permit and build your deck, so get two or three written quotes and confirm an active Maryland Home Improvement Commission license and insurance. If you would rather do it yourself, A-DIY delivers professionally engineered wood and composite deck kits to Rockville homes, and you or a local handyman can put one together with just a drill.

Contractor pricing depends on size, height, materials and permit work, so compare written quotes. A-DIY deck kits start at $3,699 for a 6x12 pressure-treated kit and go up to $12,799 for a 16x28 composite kit; a 12x12 is $4,899 in wood or $5,700 in composite. Because you supply the labor, homeowners typically spend 30–50% less than hiring a contractor. Add the permit fee to your budget.

With A-DIY, a 12x12 deck kit is $4,899 in pressure-treated wood or $5,700 in composite. A 12x16 composite kit is $6,600; the closest wood size is 12x18 at $5,969. A 16x20 kit is $7,600 in wood or $10,199 in composite. Framing, decking, footings and hardware are included.

Almost always. Inside city limits, deck permits come from the City of Rockville’s Inspection Services Division, not Montgomery County, and Rockville exempts only patios or decks no more than 7-3/4 inches above ground. Many homes with a Rockville mailing address, such as parts of Aspen Hill, Derwood and North Bethesda, are outside city limits and get permits from Montgomery County DPS, which requires a permit for all decks.

In Rockville, height matters more than size. The City exempts only a patio or deck no more than 7-3/4 inches above ground, so the model-code exemption for freestanding decks up to 200 square feet and 30 inches high does not apply. A-DIY kits sit 15–17 inches off the ground, so plan on a permit whatever size you choose.

Many customers use their A-DIY decks for hot tubs and saunas. Applicable configurations are engineered to hold up to 15,000 lbs when properly assembled and supported, but tub weight, placement and wiring vary, so talk to a deck specialist before you order and check local electrical and permit rules.

Rockville requires permit drawings to show footing size and frost-protection depth, so confirm the required depth with Inspection Services; neighboring Montgomery County DPS uses 30 inches. The City also requires floor framing within 36 inches of the ground to be inspected before decking goes on. A freestanding deck on Tuff Block footings, like an A-DIY kit, still needs a permit, and the City decides whether that footing system is acceptable.

Rockville sits between Reagan National, which averages about 14 inches of snow a year, and Dulles, which averages about 21, so winters bring a mix of snow, sleet and ice. Freeze-thaw cycles can move shallow footings, and humid summers with frequent thunderstorms test drainage and finishes. Seal wood every one to two years or choose composite decking.

Spring and early fall offer the most comfortable building weather. Apply for your permit over the winter so it is approved before delivery, and remember to book the framing inspection before you install the decking boards.

Pressure-treated wood kits come in 15 sizes: Standard 12x12, 12x18, 12x20, 12x24, 12x28, 16x16, 16x20, 16x24 and 16x28, plus Compact 6x12, 6x16, 6x20, 8x12, 8x16 and 8x20. Composite kits come in 9 sizes from 12x12 to 16x28 in Amazon Gray or Forest Wood. Custom sizes are available on request.
