Porches, Decks and Patios for Northern Virginia Homes

Our own carpenters and masons plan, permit and build the whole project, from the porch roof to the last paver.

General contractor based in Chantilly

One Company for the Porch, the Deck and the Patio

JK General Contractor builds porticos, screened porches, decks and paver patios for homes across Loudoun County and western Fairfax. Our own crew builds them, so the framing, the stonework and the schedule are all ours to get right.

We are a family business, established in 2003, so over 20 years building in Northern Virginia, and we hold a Virginia Class A contractor license. Most of our work is outdoor living, the covered rooms and stone spaces where families spend April through October.

What We Build

Carpentry and masonry under one contract. Choose one project or combine several into a single plan.

Our specialty

A Deck and a Patio, Designed as One Space

The projects we do best combine trades. A deck that steps down to a paver patio. A screened porch with a stone fire pit outside the door. An outdoor kitchen under a covered roof. When one company plans all of it, the levels line up, rainwater drains away from the house, and no one waits on another contractor to finish.

We draw the full layout first, price it in writing, and build it in an order that keeps your yard usable for as much of the job as possible.

  • Decks and porches that step down to stone patios
  • Fire pits and seating walls sized to the patio
  • Outdoor kitchens under porch roofs and pavilions
  • Walkways and steps that tie the yard back to the house

Who builds it

Our Own Crews and Our Own Trucks

The crew that builds your project has been with JK for many years, and they arrive in our trucks with our equipment.

Capitol Concrete, our sister company, is a volumetric concrete company. It supplies the concrete for footings, slabs, patio bases and driveways, so pour days follow our schedule instead of a supplier's.

How a Project Runs

Four steps from the first visit to the final walkthrough.

  1. Free on-site estimate We meet you at the house, walk the yard and talk through what you want to build. You get a firm written price, not a range.
  2. Design and materials We lay out the plan, help you choose boards, stone and finishes, and show you samples before anything is ordered.
  3. Permits and HOA approval We prepare the drawings and apply for the county permit. If you have an HOA, we give you what the architectural review board asks for.
  4. Build, inspect and clean up Our crews build it, we schedule the county inspections, and we leave the site clean. One project manager stays with you from start to finish.

Frequently Asked Questions

Do you handle permits and HOA approval?

Yes. JK General Contractor prepares the drawings, applies for the county permit and schedules the inspections. For HOA communities we put together the plans, material samples and product sheets the review board asks for.

Can you build a deck and a patio as one project?

Yes, and that is most of JK General Contractor's work. Our carpenters build the deck or porch and our masons build the patio, walls and steps, so one price and one schedule cover the whole project.

How long does a typical project take?

Ground-level patios usually take a few days to two weeks on site. Decks and porticos usually take one to two weeks once the permit is issued. Screened porches and larger combined projects take longer, and we give you a schedule with the written price.

Do you do small repairs?

JK General Contractor focuses on new construction and full replacements, such as new porches, new decks and new patios. We do not take on small repair jobs.

Are estimates free?

Yes. JK General Contractor comes to the house, takes measurements and gives you a written price at no cost.
