JK General Contractor builds outdoor living spaces in two trades. Our carpenters build porticos, screened porches, three-season rooms and decks. Our masons build paver patios, outdoor kitchens, fire pits and fireplaces, retaining and seating walls, and walkways and steps, and we pour concrete driveways.

Many of our projects use both. A deck that steps down to a patio, or a screened porch with a fire pit and a stone walk outside, is planned as one project with one price and one schedule. Inside the house, we build home additions and kitchens, finish basements, remodel bathrooms and cut in egress windows, and we build new homes. See the services below, or tell us about your project.

Which project should come first?

Start with the structure that sets the levels, usually the deck or porch. Its floor height decides how many steps come down, where they land, and so where the patio sits and how its water drains. If you build the patio first and the deck later, the deck has to fit around stone that is already set. When both are drawn at the first visit, either order works, and you can spread the cost over two seasons without the second part fighting the first.

How do carpentry and masonry fit together?

At the edges, where most outdoor projects go wrong. The bottom step of a deck stair has to land on a patio at the right height. A porch post may sit inside a paver field. A seating wall may wrap a fire pit that sits next to a porch. With both crews working for JK General Contractor, those edges are worked out once, by one project manager, instead of between two contractors who each blame the other's measurements.
