"I called Carolina Energy Conservation to have some new insulation put in my attic. The estimater came out within a few days of the phone call, and I received a detailed e-mail about what to expect. Matt gave me a good run down of what I needed to make my upstairs floor more comfortable. He called ahead of time, was on time, and was very professional. The estimate was for 4,000 board ft of insulation, 800 sq ft of radiant barrier installed, and an attic tent/hatch. Total cost was about $1600. They asked for a down payment of 30% up front, which I paid. Matt told me I would recieve a call to schedule the work within 1-2 business days. That never happened. After 1 week I called and spoke with Mary, who informed me their office manager who does schedules was out sick the previous week. She assured me he would call me back to setup a time for the work to be done. That never happened either. Fast forward another week. I called a 2nd time, and finally got an apointment setup for the following week. The two guys they sent to do the job were friendly and professional. After a few hours they let me inspect the work, and it was completed to my satisfaction. I normally have to set my AC to 73-74 in the summer to keep my upstairs comfortable, and the HVAC turns on quite often. Now I can set it to 76-77 and it remains comfortable, and the HVAC doesn't run as often. All in all I am happy with the overall experience, guess they just got hung up on scheduling."

"

They removed old debris, insulation wire and conduit. Installed a vapor barrier blocking old foundation vents. Overall they excavated the entire crawl space and installed FOAM-board insulation and 3/8 solid cement board. They sanitized all the floor joists w/micro ban-antimicrobial...A wonderful job.

"Kept in contact the whole time, let me know the process and how long it would take. Guys were all very professional and hard working. Bathroom turned out great and the insulation upstairs will surely cut down on my electric bill. It looks beautiful. will be asking them to work other projects for me in the near future."

"They installed solar panels as per contract. They were on time and removed all material when done. I had roof damage from a storm and they repaired it at no extra cost. So far I am happy with this company and plan on using them again for house repair.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

For new homeowners in Mount Pleasant, start with a professional energy audit to identify insulation gaps and air leaks. Upgrading attic insulation and sealing around windows and doors can significantly improve energy efficiency. Consider adding vapor barriers or encapsulating crawl spaces to manage humidity. Insulating and sealing ductwork, especially in unconditioned areas, is important for maintaining indoor comfort and protecting against the region’s frequent humidity and coastal weather.

Helpful?

In Mount Pleasant, create a seasonal insulation inspection routine by checking attic and crawl space insulation every spring and fall. In spring, look for signs of moisture intrusion from heavy rains and check for pest activity common to coastal areas. In fall, inspect for air leaks around attic hatches and ensure proper attic ventilation for humidity control. Regularly review energy efficiency by tracking utility bills and feeling for drafts in main living areas.

Helpful?

In Mount Pleasant, the longevity of insulation projects depends on effective moisture management, proper air sealing, and choosing insulation materials suited for high humidity and salt air. Using closed-cell spray foam or moisture-resistant batts helps prevent mold and pest issues. Ensuring complete coverage in attics and crawl spaces, maintaining correct R-values, and providing adequate ventilation are key for long-term energy efficiency and durability in this coastal climate.

Helpful?

In Mount Pleasant, insulation projects may reveal hidden issues such as moisture damage in attics or crawl spaces, pest infestations unique to coastal environments, or the need for improved attic ventilation. Additional expenses can arise from structural repairs or upgrading insulation to meet local energy efficiency standards. Permit and inspection requirements for larger projects are common. Planning for these possibilities and working with contractors experienced in Mount Pleasant’s climate can help minimize surprises.

Helpful?

Mount Pleasant homeowners can address small insulation issues by sealing minor gaps with weather-resistant caulk, gently fluffing compressed attic insulation, and clearing blocked soffit vents to improve airflow. Always wear protective gear, including gloves, a mask, and long sleeves, to guard against fiberglass and allergens. Work during cooler hours, and if you notice persistent dampness, visible mold, or electrical wiring concerns, contact a local insulation professional promptly.
