"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."

"We had a bath tub taken out and shower put in. Also, we had separate shower made into Linen Closet. They did an outstanding job. They were on time every day and always cleaned up after work."

"They repaired the kitchen floor after a serious leak as well as repaired and replaced the subfloor foundational wood beams. We were stuck because we had to have the work done prior to an appraisal of the house in a week. Surprisingly they were able to move quickly and help us out. We were delighted with the professionalism of Chip and his foreman and all the workers! We were happy to share the house with them for a couple days and very pleased with the final work."

"My bathroom remodels performed by Intelligent Home Services were the best contractor experience I’ve ever had. They performed the work on schedule, were extremely communicative throughout the process giving me daily updates on work to be performed and when to expect the craftsmen to show up, and performed quality work all for a great price. They were even there for me when unexpected water damage due to my upstairs neighbor’s pipe led to me having to jump right into a master bathroom remodel one week after finishing the spare. The tile and drywall work were impeccable. Ben, the owner and licensed contractor, stayed involved throughout the process and made frequent visits to check out the work. I am a professional engineer who works with contractors regularly so I know good project management and construction services when I see them. If you’re looking for a contractor with knowledge and integrity who can perform quality work quickly and for a great price, then look no further."

Basement Remodel FAQs, answered by experts

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

You technically can paint wires in a basement ceiling, but there are several important safety and code considerations. It's safe to paint non-metallic sheathed cable as long as the labeling remains visible. You can also paint low-voltage wires and conduit and junction boxes to help them blend into your basement. 

However, you should not paint damaged or deteriorated wiring is a fire hazard because it poses a fire hazard. The same goes for painting over high-heat wires that connect to heat-generating appliances or systems. Be sure to avoid painting multiple coats onto any wires, as that traps heat and poses fire risks.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.
