"Since 7/2025 I knew we needed insulation blown into our less than 1300 SF 1973 built home. Got a quote for over $5000, left messages at many more and some didn’t even show up or return my call. On 12/16/2025 I called Angi list and was told someone would be calling me back soon(bet they want!) Well they did and I spoke Nick Martin of Martin Home Solutions and gave me a quote that I was able to pay (We are old!) and he and Jason Farmer came to our home last evening 12/17/2025!!! (Ready To Work!) We were so impressed by Nick’s honesty, open communication and work ethic. We were so very happy to know that we can survive this winter financially with adequate insulation in our attic. Call Angi List today if you are searching for someone for your attic needs, Martins Home Solutions will not disappoint."

Insulation questions, answered by experts

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.
