"Brad and his team did a superb job installing spray foam insulation in our home in southern NH. Brad has a great understanding of how buildings work. The foam his team installed made our home incredibly and immediately warmer for a very fair price. He was upfront and very well reasoned about what would and would NOT work for our ice dams and cathedral ceilings.. His company scheduled us and completed the job faster than all the other contractors offered to do. He also offered a better price out of four bids. I feel that we really were lucky to have chosen Brad to do the work. We received four bids, some were substantially more expensive. And yet, Brad offered the only solution that made sense to us and that actually WORKED. The install went very fast. 24 hours post installation, we had zero smell. Our home was left as clean as when they started the work. I am extremely impressed."

"Roland did an excellent job. He explained the things I needed and those that I didn't. He was right on time and finished the job in the time he stated. He was very professional and knew what he was doing. If you are looking for a straight shooter without any of the sales frills (and the larger cost) then Sav-On Insulation should be your choice."

Insulation questions, answered by experts

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

There are two reasons why cellulose insulation repels rodents (and insects). First, the insulation has been treated with boric acid, which is a natural pest-repellent. In addition, the loose-fill style of cellulose creates less-than-ideal conditions for mice and other rodents to nest and burrow, helping to keep them at bay.
