Deck Builders Near Me in West Chester, PA? Build Your Own Deck With an A-DIY Kit

You can do either. Deck contractors working in West Chester and the surrounding Chester County townships handle design, permits and construction, so collect two or three written quotes and ask about recent projects inside the borough, where lots are often tight and every deck needs a permit. If you would rather build it yourself, A-DIY delivers professionally engineered wood and composite deck kits to West Chester homes, and you or a local handyman can assemble one with just a drill.

Contractor pricing in West Chester depends on size, materials, site access and labor, so written quotes are the only reliable number. A-DIY kits are priced upfront, from $3,699 for a 6x12 pressure-treated kit to $12,799 for a 16x28 composite kit, with framing, decking, Tuff Block footings and hardware included. Homeowners who build a kit themselves typically spend 30–50% less than hiring a contractor.

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. West Chester Borough has amended the Pennsylvania Uniform Construction Code to require a building permit for an uncovered deck regardless of how high the floor sits, so the state exemption for low decks does not apply inside the borough. Apply to the Building, Housing and Codes Enforcement department at 401 East Gay Street through the borough's online permitting portal. Homes in the historic district may also need a HARB Certificate of Appropriateness. If your West Chester mailing address is actually in West Goshen, East Goshen, Westtown or another township, that township handles the permit.

Inside West Chester Borough there is no permit-free deck size: the borough requires a building permit for any uncovered deck, whatever its height or footprint. In many surrounding townships, the Pennsylvania UCC exempts an uncovered deck whose floor is no more than 30 inches above grade from the building permit, though zoning permits, setbacks and local amendments can still apply. Check with the office that covers your exact address.

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.

Footings for attached or elevated decks in Chester County generally need to reach 36 inches below grade, the minimum frost depth written into codes such as West Whiteland Township's; confirm the borough's requirement when you apply. A freestanding, or floating, deck is not attached to the house and typically sits on surface footings. A-DIY kits are freestanding, assemble 15–17 inches off the ground and include Tuff Block footings, but inside the borough they still need a permit.

West Chester sees cold winters with repeated freeze-thaw cycles, occasional snow and ice storms, humid summers and frequent summer thunderstorms. Choose a level, well-drained spot, keep the gaps between boards clear so water runs off, check a freestanding deck for level each spring and seal pressure-treated wood every one to two years, or pick composite decking to skip staining.

Spring and early fall are the most comfortable building seasons, with April through October the usual window. Because the borough requires a permit for every deck, start your application in late winter, time your kit delivery for after approval and aim to build before the hottest, most humid weeks of July and August.

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.
