JLC Building Co. brings over 15 years of experience and a dedication to the highest quality and standards of craftsmanship. We have completed hundreds of renovations, additions, and new construction projects - both large and small scale. Customer satisfaction is our primary objective. Each project deserves the up-most importance and we strongly believe in working with each customer to build their vision.  JLC practices honest pricing, quality materials, beautiful installations, and strives to maintaining a clean work space. Whether a gorgeous tile job for that new bathroom, a kitchen remodel, or a new deck addition, give us a call! Licensed in the State of New Hampshire and fully insured through Liberty Mutual.

"I am writing Home Advisor to let them know how pleased I am with the service I received from JLC building company. The latest home improvement Jay completed for my wife and I was a combination, carport / deck. I had Jay expand the Inlaw apartment in the lower level of our house. This expansion took over my garage which lead to the need for a carport. Jay constructed the carport with pressure-treated beams and it came out great. However, it was the deck above the carport that really stands out. Jay used composite decking that was secured to the carport. He used fasteners that locked in the decking without the need to drill holes in the decking itself. This resulted in a beautiful deck that did not have hundreds of lines where the screws fasten the decking to the framework. Jay, then recommended a dark railing system that blended in with the surrounding woods. The dark railing is so much better than the white railing we have on the other side of our house. That white railing was here when we purchased the home and it optically closes in the deck and draws your attention away from the natural surroundings. After completing the deck, Jayâ s crew removed a window and installed an awesome slider. The slider gives us access to the huge deck from our middle floor. It has adjustable louvers inside the glass which allows us to view the beautiful outdoors or choose to have privacy without the need for drapes. Jay finished the job with white shiplap inside which accented the living room perfectly. I am not sure what our next project might be but I do know that JLC builders will be doing the work. Rick"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
