"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"This is the most negligent contractor I've dealt with in my life. They suggested to not be home for our attic insulation since we have a newborn at home which I appreciated. They seemed careful and thoughtful in the sales process which is why I ended up picking them for our project. However, when it came time for the job they were reckless with security and safety. Before the job I sent multiple notes via text and email, and had a phone call asking them to contact me at the end of each day so I could set the alarm and lock the doors remotely. Day one they didn't do this. I sent another ask to please be mindful of this so I could keep our home secure. Day 2 they did not do this again, and ended up leaving our front door wide open which triggered a burglar alarm at 2am requiring us to deal with the security company and police throughout the night. Afterwards it took days for anyone to reply. They lacked empathy or ownership for how negligent their team was. I would not recommend working with these people. Mistakes happen, but the response to these mistakes was almost as bad as their dangerous actions themselves."

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"It began with David spending time with us in our home reviewing the strengths and weaknesses of our current setup. And ended with a very thorough crew installation (Antonio and Maurice) at our Western 'burbs home. My wife and I have already recommended to several family members based on our sound experience with the team. If you are looking for professional, I would look no further."

"Steve Gavin, the owner came out and provided me with a great price that was inclusive of the entire scope of the project. During our meeting he took the time to explain the process that his company uses. Once the permits were issued the crew arrived the next morning at 7:00 a.m. as promised. The crew met the deadline for a 1:30 inspection from the Village of Deerfield. They not only met the deadline but they passed the inspection without any issues to be corrected. The crew worked until 7:00 p.m. completing the job. I would also note that they left my home spotless!"

FAQs for spray foam insulation projects in Chicago, IL

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
