"I have remodeled 5 homes and built one. With all my experience with contractors and subcontractors, I have never found one as reliable as Carson. He has helped my family with repairing older beach homes for the last three years. We have hired Carson to do a lot of jobs. He has completed all of them in a timely manner, using salt water resistant materials that will stand the test of time, and the end product demonstrates excellent craftsmanship. He helps us make decisions from 200+ miles away, staying on budget but producing excellent results. We haven't had to stress about overseeing the job as Carson treats our house as his own. We are beyond thankful for him, his team, and his attention to detail. My great grandfather built one of the homes in the 1950's and its withstood many Hurricanes. I'm so thankful that Carson can carry the tradition of excellent craftsmanship to our special place. As for specifics of this job, he built beautiful shiplap in our den, repaired our deck, replaced a rotten support beam with plumbing and electrical running through it, and painted our porch and deck. He did an incredible job."

"Our experience with Mt Valley Foundation was outstanding. Patrick E., the Ceritified Field Inspector, conducted a very thorough inspection of our crawlspace. Then he presented us with all of the details and photographs of his inspection. He spent an hour answering all of our questions and then presented us with our options for our sagging floors and foundation structural repair. His expertise was invaluable. The installation crew, Joe and Stephen, were prompt, courteous and very professional. Joe, called and texted us to let us know that they were arriving soon. Upon arrival, he posted the work permit and then discussed, in detail, including pictures, what they were about to do. After installing the steel beams and IntelliJack support system, our sagging floors and baseboards were returned to normal. When they were finished, they discussed what they had done and provided pictures of the completed work. Great job Joe and Stephen! We highly recommend Mt Valley Foundation in Charleston."

"I feel Commonwealth Contracting is very easy to work with. Mike Eippert always responds to any questions we may have had during the process of the work. This is the second major renovation we have had done with "Commonwealth" and both times we were very happy with the results. I will say you need to be patient with how long the project may take. We realized all of these contractors are extremely very busy at this time. However, quality was much more important to me than speed, and all of the work we had done is outstanding. As far as price they are not the cheapest nor the most expensive, however, I feel comfortable that what we paid for the complete renovation was very fair. To me "Quality" of work done is most important and that is what "Commonwealth" provides."

"WOW! Being on a fixed income you know EVERY dollar is important to me! I'd wanted and DRASTICALLY needed a bathroom remodel for YEARS but assumed it was WAY out of my budget! Curious though, I went shopping. Most companies estimates confirmed my worries about cost, and while some were affordable they lacked in other areas - quality, customer service, warranty, etc. When I related my findings to a friend he said members of their family had work done by a company called Intelligent Home Services and HIGHLY recommend them! His family was not only overjoyed with all aspects of the company but it increased the value of their home by much more than what it cost! So, I contacted IHS, everyone was so nice, informative, and helpful! They arranged financing was straightforward, explained and everything. It was great from start to finish! In fact I was SO HAPPY that I had Intelligent Home Services install a Screened Patio cover! EXCELLENT VALUE- THE BEST!!!"

FAQs for basement remodeling projects in Johns Island, SC

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
