"Nick and his crew were so informative and pleasant to do business with. We had attics insulated, new vents installed, and outside blown-in cellulose, and they worked long hours to make sure everything was done correctly. I would definitely recommend this business. A great surprise was how the insulation muffled loud outside noises (fireworks and loud vehicles)."

Insulation questions, answered by experts

If the outside temperature drops below 20 degrees Fahrenheit, it will take around six hours for your pipes to freeze—and they might even burst. That’s why keeping your mobile home’s temperature around 50 to 60 degrees Fahrenheit is necessary, even if you’re leaving it vacant for the winter. In addition, having ample skirting around the mobile home's underbelly will help keep pipes insulated during the winter. 

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.
