"We got several quotes for our attic insulation project. We found Jace with Peak Performance to be very knowledgeable, honest and reasonably priced. We scheduled the project, the Peak team showed up on time, finished in the timeframe they promised and did a full clean up. We're really happy with the entire experience and have already recommended them to others."

"I had three different people groups in who came in and gave me an estimate and what might be needed and what they discovered is that for some reason when the house was built 16 years ago, they did not really do adequate insulation.  I did feel very comfortable with Precise & Snug.  They were good about being able to show me pictures.  They showed how it looks up on the attic.  When you are in the process, the told us that they can do this and that and it would cost so much and the final bill was $20,000.  I would not use their service in the future."

Insulation questions, answered by experts

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

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.
