"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."

"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

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.
