Contact Us

We are based on Gum Spring Road in Chantilly. Most of our projects are within a short drive of the shop, in the established neighborhoods of western Fairfax and the newer communities of Loudoun County and western Prince William.

Why do we stay close to the shop?

Because a short drive means a full day of work at your house. A crew that spends an hour in traffic each way loses most of a day over a week. Staying close also means our trucks, our equipment and our concrete supply can reach the job the same morning they are needed, and someone can stop by quickly if a question comes up.

It also means we know the ground. We have filed permits in all three counties, sat through HOA reviews in the big planned communities, and dug footings in the clay soils that run through much of this part of Northern Virginia. That local knowledge shows up in the plan before the first shovel goes in.

Permits in Three Counties

Loudoun, Fairfax and Prince William counties each run their own permit offices, with their own forms, plan requirements and review times. We file permits with all three and schedule the inspections, so you do not have to learn the process for your county.

HOA Communities

Many communities here, including Brambleton, South Riding and much of Ashburn, have architectural review boards that must approve outdoor projects before work starts. We prepare the drawings, material samples and product information the board asks for, and we wait for approval before we build.

What do we build in each area?

The same services everywhere, with a different mix. In the newer communities of Loudoun and western Prince William, most calls are for screened porches, outdoor kitchens and patios on houses that came without them. In western Fairfax, many calls start with an older deck that needs replacing, or a front entry that needs a portico. See Porches and Decks, Patios and Hardscapes and Additions and Remodeling for what each crew builds.

Which towns are closest to the shop?

Stone Ridge and South Riding, which the shop sits beside, then Chantilly, Brambleton, Centreville, Aldie, Haymarket and Gainesville, all within about eight miles. Those are the towns where we can most easily fit a site visit around your schedule. Broadlands, Sterling, Herndon, Ashburn, Reston, Clifton, Bristow, Lansdowne and Leesburg are regular territory, and we build farther out, in Middleburg, Oakton, Fairfax, Nokesville, Vienna, Great Falls, Purcellville, Hamilton, Waterford, Round Hill, Lovettsville, Woodbridge, Arlington and Warrenton, when the project is a good fit. Catharpin, a few minutes south of the shop, and Manassas are close by too.

Frequently Asked Questions

My town is not on the list. Can you still help?

Call JK General Contractor at (571) 437-2511. If the project is a good fit and within a reasonable drive of Chantilly, we will come out and look at it.

Do you charge for estimates?

No. JK General Contractor's estimates are free.

How soon can you come out?

We call you back the same or next business day to set a time for the visit. Spring and early summer book up first, so call ahead if you want warm-weather dates.

Which county is my house in?

Your tax bill or the county's property search will say. Near Chantilly the line runs through the middle of town, so JK General Contractor confirms the county for your address at the estimate before filing the permit.
