When your family outgrows your home but you love your neighborhood, a well-built addition gives you the space you need without the hassle of moving. Integrity Construction & Remodeling designs and builds home additions in Summerville, SC that look like they've always been part of the house — matching your rooflines, siding and trim so the new space blends in seamlessly. Whether you're dreaming of a bigger kitchen, an extra bedroom or a sunroom, Jason Carter handles your project personally from the first walkthrough to the final coat of paint.

Why choose Integrity Construction & Remodeling

  • You work directly with the owner. Jason quotes your project and is on site building it — no salespeople, no revolving crews, no wondering who's in charge. The person who understands your plans is the person swinging the hammer.
  • Additions that match your home. A good addition shouldn't stand out. We take care to tie into your existing foundation, roofline and finishes so the new square footage feels original, not bolted on.
  • Honest quotes and clear communication. You'll get a straightforward estimate and regular updates as the work moves along. We talk through decisions before they cost you money, so there are no surprises when the invoice arrives.
  • Local knowledge that keeps things moving. As a Summerville-based contractor, we know the permitting and inspection process in Dorchester, Charleston and Berkeley counties, which helps your project stay on schedule.

Our Home Additions process

  1. On-site consultation. We visit your home, listen to how you want to use the new space, and talk honestly about what's possible within your budget.
  2. Design and estimate. We help shape the layout and provide a detailed, written quote so you know the scope and cost before any work begins.
  3. Permits and planning. We handle the permit applications and coordinate inspections, and we set a realistic timeline so you know what to expect week to week.
  4. Foundation and framing. We build the structural bones of your addition — footings, framing, roofing and weatherproofing — tied cleanly into your existing home.
  5. Systems and finishes. Electrical, plumbing, HVAC, insulation, drywall, flooring, trim and paint come together to make the space livable and comfortable.
  6. Final walkthrough. We review the finished addition with you, address any last details, and make sure you're genuinely happy before we call the job done.
