I am far from a handyman but the wife wanted a deck in the backyard and I couldn’t see myself dishing out $20,000 for someone to come build it for us. I ended up seeing an ad for this company and was blown away by the price and ease of install. 2 of our neighbours ended up ordering as well!

Planning a Deck in Loudoun County: Climate, Snow and Weather Considerations

Loudoun stretches from the Potomac River and the Dulles corridor west to the Blue Ridge, but the whole county shares a humid four-season climate: muggy summers with thunderstorms, a wet spring and winters that swing between snow, ice and mild spells. Higher western lots can run cooler and windier than eastern Loudoun.

Built for Loudoun’s four distinct seasons Built for Loudoun’s four distinct seasons

Winter Storms

Dulles Airport averages about 21 inches of snow a year, and the higher ground out west can pick up more in some storms. Applicable A-DIY configurations are engineered for up to 15,000 lbs when properly assembled and supported, but clear heavy snow promptly with a plastic shovel.

Frost and Footings

Loudoun County’s deck guidance lists a 24-inch minimum footing depth on solid soil. A-DIY kits are freestanding and sit 15–17 inches off the ground on Tuff Block footings, so show the footing details on your permit drawings and confirm what the County accepts for your lot.

Rain and Soil Drainage

Dulles records about 43 inches of precipitation in a normal year. Where yards have heavy clay soil, water can linger after storms, so pick a spot that drains well and keep airflow under a ground-level deck.

Summer Heat and UV

Hot, humid summers fade and check unsealed wood. Plan to seal pressure-treated decking every one to two years, or choose composite in Amazon Gray or Forest Wood for low upkeep.

Loudoun County Deck Permits and Building Code Information

In Loudoun County, who handles your deck permit depends on where you live. The County’s Department of Building and Development issues building permits countywide, including inside the incorporated towns, while zoning approval comes from the County in unincorporated areas or from your town if you live in one.

Rule of thumb: every deck in Loudoun County needs a building permit and a zoning permit, whether it is attached or freestanding.

Loudoun County Deck FAQs

Are there deck builders near me in Loudoun County, VA, or can I build a deck myself?

Both. Contractors across Loudoun build custom decks; compare written quotes, check for a Virginia contractor license and insurance, and ask about recent projects in your part of the county. To build your own, A-DIY delivers professionally engineered wood and composite deck kits anywhere in Loudoun County, and you or a handyman can assemble one with a drill.

How much does it cost to build a deck in Loudoun County, and is DIY cheaper?

Contractor quotes vary with size, height, materials, stairs and site access, so collect several before you decide. A-DIY kits range from $3,699 for a 6x12 pressure-treated kit to $12,799 for a 16x28 composite kit, and homeowners typically spend 30–50% less than hiring a contractor.

How much does a 12x12, 12x16 or 16x20 deck cost?

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.

Who issues deck permits in Loudoun County?

Loudoun County’s Department of Building and Development issues building permits for decks across the county, including in the incorporated towns. In unincorporated areas such as Ashburn, Sterling, Brambleton and South Riding, the County also issues the zoning permit. In Leesburg, Purcellville, Middleburg, Hamilton, Hillsboro, Lovettsville or Round Hill, get the town’s zoning permit first and include it with your County application. County questions: 703-777-0220.

Is any deck exempt from a permit in Loudoun County?

No size or height is exempt. The Virginia Uniform Statewide Building Code exempts sheds up to 256 sq ft but does not list decks, and Loudoun County requires building and zoning permits for all decks. Freestanding decks, decks with roofs and decks with hot tubs need full plans rather than the County’s Typical Deck Detail.

Can I put a hot tub on an A-DIY deck?

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.

How deep do deck footings have to be in Loudoun County, and are floating decks allowed?

The County’s deck guidance sets a 24-inch minimum footing depth, with footings bearing on solid soil. Freestanding (floating) decks go through the same permit process with their own plans. A-DIY kits are freestanding, assemble 15–17 inches off the ground and include Tuff Block footings, so show those details in your drawings and confirm what the County will approve for your site.

What weather should I plan for when building a deck in Loudoun County?

Loudoun has hot, humid summers with thunderstorms, a wet spring and winters with snow, sleet and freeze-thaw cycles. Dulles Airport averages about 21 inches of snow and 43 inches of total precipitation a year. Build on a well-drained spot, leave airflow underneath and choose composite if you want to skip regular sealing.

When is the best time to build a deck in Loudoun County?

Spring and early fall offer the best building weather. Start permits in winter, especially if you need a town zoning permit before the County building permit, so your kit can arrive once approvals are in place.

What deck kit sizes does A-DIY offer?

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.

Does A-DIY deliver deck kits throughout Loudoun County?

Yes. A-DIY delivers curbside by LTL freight to eastern Loudoun communities like Sterling, Ashburn, Brambleton and South Riding, to Leesburg and Lansdowne, and west to Purcellville, Hamilton, Round Hill, Lovettsville and Middleburg. Delivery typically takes 10–14 business days. On long rural driveways, plan for the drop-off at the road.
