"I very much enjoyed my experience with C&S Fencing and Insulation. All my interactions with them were pleasant; their bid was easily the best I got; and when Shawn arrived he got the job done very quickly by himself. I like watching an expert at work, and today was an education in efficiency. Kudos to C&S Fencing and Insulation!"

"I am the general contractor for the construction of my new house and I wanted a reputable insulation company to perform the installation. GAPFIL's product knowledge was better than the nearest competitor (Bluegrass) and offered more choices such as hybrid spray foam and blow-in blanket systems. The competition tried to steer me into open cell spray foam exclusively which appears to be a better system but in fact cheaper for the installer giving him a higher profit margin. I decided to go with the hybrid system which was cheaper for me and more effective at insulating. I recommend GAPFIL."

"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."

"They arrived on time and completed the work in a timely manner. I was very pleased with their work. They also installed at an earlier time plastic under my house. They even noticed that insulation work I had done by another contractor was not completed. I called the contractor and told him they noticed his work and he came back and finished the job.  I didn't know it at the time, but they also install insulation. I would use them again."

"Over a period of approximately 3 weeks, water-damaged, drop ceiling tiles, drywall/insulation and carpeting was removed from a basement bedroom following a leak in a water pipe in the ceiling. They treated the studs to remove mold and left a dehumidifier/ large fans to dry out the studs and floor. 
Installed new insulation and drywall, new ceiling tiles, then painted entire room. Carpet was re-installed in the bedroom and stairwell so carpet would match throughout.
The work performed was excellent and personnel were courteous. Besides having some issues with the personnel arriving when scheduled to arrive, we were very satisfied with the whole experience.

Insulation questions, answered by experts

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

The lifespan of insulation depends on the material type. Fiberglass can last between 80 and 100 years, but it is important to start checking it around the 15-year mark. Spray foam has a lifespan of up to 100 years, and mineral wool can last up to 100 years. Cellulose, an eco-friendly option, has a lifespan of 20 to 30 years.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
