"Can say enough great things about Ben and his team. These guys showed up on time and were incredibly professional. They did all of the prep work and left the attic cleaner than they found it. Some of the foam came out through this old house and got on to the outside siding. The team not only went up 30 feet on a ladder to get it off - but they also touched up the paint. Amazing A+ work"

"My husband and I were very pleased with the work that was done. The company owner, Greg McBride, was wonderful to work with. He did exactly what he said he would do and completed the job exactly when he said he would. If he had to come a little late, he called to tell us. He went above what we had expected, even upgrading some of the materials he used at no extra cost to us. The men on the crew were also very professional and did an excellent job. We also felt our cost was very fair. We are so glad we had this done."

"I needed to add a bathroom and utility area, but did not want to increase a footprint of the house and decided to incorporate my carport into a living area. It allowed me to save on roofing and foundation, but created certain logistical difficulties in the project. Mike and his crew have creatively addressed all the issues which allowed me to maximize the living area while still being compliant with all the building codes. Work on the project was well planned and performed according to the schedule. In fact it took longer to wait for building permit from the county than the project itself. I also wanted to point out that Mike possesses a rare quality for contractor, he is very punctual and responsive. He had returned all my calls/e-mails within a day and had addressed all my concerns or requests in a timely manner. It was a pleasure to work with Mike and his crew and I would hire them for my next project without hesitation."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Johns Island, SC

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
