"Professional and courteous. The folks on site took time to answer any question, wore masks and cleaned up well. They did great job painting the stucco after insulation and patching - house looks great. The insulation is already making huge difference in my 1911 house in Minneapolis- not sure the boiler will kick in till December."

"We’ve had a great experience working with this company on several projects. They’ve completed batt insulation, spray foam, and blown-in insulation for us, and the quality of their work has always been excellent. Their team is knowledgeable, reliable, easy to work with, and does a great job keeping things clean and professional on the jobsite. We appreciate their attention to detail and consistent communication and would highly recommend them for any insulation needs!"

"John and his team did amazing work removing the old, insufficient insulation in the attic of my nearly 120 year old home and replacing it with a much higher R-value blow-in insulation. The difference in the look of the attic is phenomenal, and I am confident it will be good for the energy efficiency of our home as well. The entire project took around 8 hours and the team even cleaned up to the point where you could hardly tell any work was done. I found dealing with John and Spray Foam Insulation Systems to be a very pleasant experience. Very honest and forthright, while offering a very fair rate for the work. I highly recommend working with them."

"We called Home Seal to consult on weatherization and insulation for our 1920s bungalow. The advice was great and we hired them to insulate the rim joists between our basement and first floor as well as adding cellulose insulation to our attic space. The communication throughout this project went well and the work was completed as scheduled. We would highly recommend Home Seal for weatherization and insulation projects."

"The project: insulate the unfinished basement rim joist. The job looks great, very even, uniform depth, no big over-sprays, all cavities sealed and a good cleanup. I recommend them and would use them again."

"I could not be more impressed with Jesse and his team. They were so responsive, so professional, and so incredibly helpful. Great communication throughout. Great work product. Pricing that was very competative and reasonable. The next time I have an insulation need I won't even both to get bids from other shops. I will just use Century. Highly recomend."

"The estimator for our garage insulation project from Home Pro, Lyndsay Praml, was excellent. She was extremely knowledgeable regarding the type of insulation to use and the attic venting needs. Lyndsay actually climbed into the attic space over the garage to inspect and measure the space. We would have used Home Pro had not our overall kitchen/garage contractor come up with their own contractor."

Insulation FAQs, answered by experts

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

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.

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.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

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.
