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

Yes to both. Bethesda has plenty of deck contractors who handle design, County permits and construction, so compare two or three written quotes and check that each holds an active Maryland Home Improvement Commission license. If you prefer to build it yourself, A-DIY delivers professionally engineered wood and composite deck kits to Bethesda homes, ready to assemble with just a drill.

Contractor quotes in Bethesda reflect labor, materials, site access and permit drawings, so they vary from yard to yard. A-DIY kits range from $3,699 for a 6x12 pressure-treated deck to $12,799 for a 16x28 composite deck, and a 12x12 is $4,899 in wood or $5,700 in composite. Since labor is a large share of a contractor’s price, homeowners typically spend 30–50% less building a kit themselves.

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.

Yes. Bethesda is an unincorporated part of Montgomery County, so the Department of Permitting Services (DPS) issues deck permits, and DPS requires a building permit for all decks regardless of height. Some nearby incorporated towns and villages in the Chevy Chase area have their own requirements; the Town of Chevy Chase, for example, requires a town permit once the County permit is issued.

No. Montgomery County does not use the model-code exemption for small, low, freestanding decks of 200 square feet or less; DPS requires a permit for every deck. Zoning setbacks and lot coverage still apply, and HOA or historic district approvals may be needed, so check those before you order.

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.

DPS deck guidelines require footings at least 30 inches deep, bearing on solid soil. A floating, freestanding deck is not attached to the house, but it still needs a permit, and DPS decides whether a ground-level footing system works for your lot. A-DIY kits are freestanding on Tuff Block footings and sit 15–17 inches off the ground, so include those details in your plans.

Bethesda has hot, humid summers with frequent thunderstorms and winters that bring a mix of snow, sleet and ice; Reagan National averages about 14 inches of snow a year. Freeze-thaw cycles can shift shallow footings, and heavy tree cover means decks stay damp longer after storms. Keep boards clear of leaves, and seal wood every one to two years or choose composite.

Late spring and early fall usually bring the best building weather. Since every deck needs a County permit, plan and apply over the winter, then schedule delivery once your permit is approved so you can build as soon as the weather turns.

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.
