“First off, I recommend Jo and Insulation Co 100%!! I had some organic growth in my attic space that I needed to take care of. I researched and looked at reviews and contacted a few companies that serve the Edmonds area. Most of these companies might have OK reviews, but they are franchise companies from out-of-state that will charge almost double the amount. On the contrary, Jo has been local and doing this stuff for the family business since he was a kid and is very knowledgeable. I am hands-on and like details and Jo was more than happy to hang out on the phone and chat about the whole process. I could tell he genuinely cares about the best possible solution for your home, and is constantly testing and validating the effectiveness of products on his own home. Julio and the team that came to my house the day of were prompt, professional, and answered all the additional questions I had. I like to do most things by myself and usually have a hard time trusting someone else or service, but this was a great experience all around and I highly recommend Insulation Co. for any Attic/Crawlspace service you might need."

Austin James

"We asked Jo Insulation Co to clean, remedy the mold, and install insulation for our crawl space two years ago when we bought our house. They showed up on time and did a thorough job. Since then we had no problem with our crawl space and each company who inspected our house commented that the work had been done well for the crawl space. We recently discovered that our house has a small disconnected crawlspace. Although it has been two years since the initial crawl space project, Jo agreed to get that done for us at no cost, and again the team showed up on time on the specified date. Our neighbor also hired Jo Insulation Co for their big insulation installation project, and they were very happy with the company. I strongly recommend them and we will definitely contact them for our future insulation projects for our attic etc."

“Those guys did a great job and were quick. It was hard finding someone that would indicate the house from the outside and they got it done."
