"They applied spray foam insulation in my attic space. I can now use this space for storage. The crew provided were very personable, they explained what the process works and how the project will go, and while on the job site they exhibited Professional behavior and worked cleanly. They took extra efforts to not track debris into my home."

"I hired KJ Drywall to frame, insulate, and sheetrock/texture a basement bedroom. Kevin did a great job. He was very knowledgeable about what needed to be done. He worked very hard and completed the job in a good time. He seems pretty efficient. We had a plumbing issue during his work, and he had someone out to fix it within about 45 minutes. The repair was made in Avery professional manner. Long story short, this fellow and his help were very good to work with, very fair with the price, And Kevin seems like just a really good guy. Glad to have worked with him."

"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 FAQs, answered by experts

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Yes, covering exposed wires is necessary for several important reasons. Exposed electrical wires pose significant risks, such as electrical shocks, fires, short circuits, and potential damage to your home’s electrical system. By properly insulating and protecting the wires, you can minimize the potential for accidents, prevent electrical fires, and ensure your electrical system stays intact. 

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.
