"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."

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."

"Ryan did our estimate, and was very efficient. Andrew and Evan did the insultation work and did a fantastic job! It was a large area to get prepped and then to insulate and they did a great job every step of the way! Our entire home is now at a R50+ insulation level, as opposed to the R25-30 and 0 values we had before. It will be interesting to see what sort of impact the newly insulated garage and 3 season porch has on the comfort level in the main house. The team did a great job for us and I would recommend them to anyone considering insulation!"

"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

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.
