    Insulation Co - Crawl Space & Attic Cleaning

    Phinney Ridge, Greenwood

    My house was due for a crawlspace and attic cleanout. I reached out to several contractors and got…read morequotes from at least 5 different companies. Insulation Co gave me the best price out of all. The owner, Jo, was very knowledgable and easy to talk to. He was always willing to jump on the phone to answer any questions, which I appreciated a lot. My house was built prior to 1989 so I received a nice PSE rebate for the work. On the day of, Jo's crew were quick and efficient and provided Before and After photos. They removed my old vapor barrier and insulation and replaced with new one, added new dryer vent duct and flapper, and added new roof vents for all my bathroom fans, and much more. I was able to ask them questions during and provided water and snacks to them for their hard work. The crew respected my home and cleaned up after themselves before leaving. After the work was completed, I thanked Jo for making this all possible and being easy to work with. We went over some of the After pictures together over the phone to help me learn about everything and ask additional questions. They even sent a crewmember to come back for a 2-week follow-up on the work to make sure everything still looks good. I would recommend Jo and the team at Insulation Co to my friends and family for attic and crawlspace cleanout services again.

    I highly recommend Isulation Co. We had another contractor remediate mold in our attic, so I…read morerequested bids from 3 companies to install new insulation. Jo responded almost immediately with a bid based on the dimensions of our attic (he consulted the King County Parcel Viewer site to determine them). The other companies scheduled inspections. These were great for my ego: apparently I am very fit for my age, have excellent taste, and I'm very nice, so they offered me 'special discounts' . However, when I compared the bids for equivalent services, Insulation Co was significantly less expensive. No 'special discount' required; just straightforward pricing. The crew arrived on time, were careful to protect our property, and did excellent work. They took photos of their work and reviewed them with me. We had an issue with a switch for our bathroom fan that I mistakenly suspected was related to the installation. Jo responded immediately when I informed him of my suspicion and had someone come out the next day to troubleshoot it. Great service. Great value. Honest.
