My house was due for a crawlspace and attic cleanout. I reached out to several contractors and got quotes 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. read more

Too much wrong to even begin to say. The service I requested was not completed. What little was done was about the quality of a toddler. Not sure what the deal was I'm waiting to find out the results of the testing to be sure. read more

Fair pricing. Almost half the price of competitors that use sales representatives and fancy apps. Told them what I wanted and got a price without having them come out. Was quick to clear out and replace insulation and fabric in my crawlspace over just a couple of days. read more

I highly recommend Isulation Co. We had another contractor remediate mold in our attic, so I requested 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. read more

Very professional. They put a vapor barrier and insulation in a very tight space under our cottage. Really appreciated the photos they provided of the before and after work. Price was fair and they cleaned the site after all the work. read more

This was truly a great experience. I can't recommend Jo enough. His prices are incredibly reasonable and it was refreshing to just get a straight forward bid without all the other frills that other companies try to up-sell you on with their scare tactics and "specials" His team showed up on time, worked non-stop, were professional and courteous. And the price was by far the best. Thanks Jo. read more

I was very impressed with this company from start to finish. They were the first to respond to my request for an estimate, and it was detailed and specific. Their estimate was so much lower than the other two estimates that I got that I actually asked them to analyze the other estimates to see what different activities were being included. Jo got on the phone with me immediately-- late on a Friday afternoon and the projects were scoped the same. Their estimate was just way lower. They scheduled within a week. The work itself was timely, efficient, and super professional. Would definitely use them again read more

I am having my attic cleaned and sanitized and insulation replaced. I picked Crawl Space Pros because they had the best reviews and would do the service all in one day. They have been great so far and I anticipate a "job we'll done"! read more

Excellent experience using Insulation Co. and would definitely recommend if you are looking for new insulation in your attic. Bought a 1958 house which had a mix of vermiculate and batting insulation in the attic, along with mold in the attic due to a bathroom vent that terminated in the attic since the 1950s. I called several insulation companies, and the estimate process with Jo at Insulation Co. was the easiest. I called and explained what I needed, and I got an official email listing out the price right after the phone call. The estimate was crystal clear because it included a list of all of the changes that would be made. The price was good and they could schedule me very quickly. The guys were very efficient with the install and very respectful of my home, kept the work area clean, and answered all of my questions. They took pictures of the end result so I could see what it looked like without having to go up there myself. I have noticed a difference in my monthly electricity bill. My house stays warmer longer in the Winter and stays much cooler in the summer. No a/c in my house so I depend on my insulation to maintain the temp. read more

I needed my attic insulation replaced, and my crawlspace cleaned, sealed against rodent intrusion, and re-insulated. Jo's team showed up promptly. After removing the existing blown-in attic installation, they replaced a flexible bathroom vent pipe with metal, sealed it with mastic, and insulated it. They also sealed other vents before reinsulating them, and filled a number of cracks with spray foam before blowing in the new insulation. They custom-built a new crawlspace hatch for us, cleaned up the crawlspace, replaced all the insulation, and installed plastic sheeting. They did an excellent job, completing it sooner than I would have believed, and for a reasonable price. A++ read more

Jo is so responsive and his team was a pleasure to work with. I called one day while calling around for crawl space and attic cleaning and insulating. I didn't get an answer. Then he called me back within 5 minutes. He reviewed a couple of other quotes I received and was able to beat the competitors prices! While on the project the guys are respectful and thorough. They communicated well with us and each other and cleaned up after themselves. Super happy with the service and will recommend to others. read more

I hired the Insulation Co and it was the right choice. First let me say if you need crawl space services I whole heartedly recommend this company. The owner Jo, was so responsive, he listened to my needs and concerns, and every time I reached out to him prior to the work being done and even after it was done, he was so quick to respond. I will also add, Jo was very patient with my many questions. I needed the crawl space cleaned, sealed, and new heating ducts installed. This was a very difficult job as the crawl space has very low clearances. They did so many things like disinfecting, wrapping the plumbing, sealing the new ducting, sealing the crawl space from outside intruders. Very thorough!!! I cannot say enough good about the job the crew did, 4 folks the first day and 3 the second day. Raphael was the team lead and he was great to work with, he listened to the concerns that I had and kept me updated throughout the two day job. Raphael, would show me pictures when I had questions about things under the house. He was awesome to work with. My crawl space entry is in a small clothes closet in a carpeted room and this was a dirty job but you would not even know they had been here. They protected the carpet as well as our teak hardwoods that lead to the entry of the house. Outside was the same, no debris at all. Highly recommended! read more

Fantastic company and an even better work crew. They did a complete mold remediation of our crawlspace.

Jo and his team were top notch. They did a crawlspace clean out for me and added insulation, wrapped pipes, ducts etc. 1955 house house so it needed a lot of work. Crew was very professional and did a fantastic job! read more

I really appreciated Jo's communication upfront about the services he offers, the process of installation, and even some good information about his competitors in the area! I had several quotes done and I definitely felt most comfortable with this company as the best value for money. The crew arrived on time and took care to keep everything tidy and my walls and floors protected throughout the process. They finished the clean out and insulation blow in process within the time window Jo had mentioned, and the attic looks great now!! I had 40-year old insulation that had flattened down to an almost useless barrier, and a huge old tv antenna stuck in the rafters. Now it's all cleaned out and the new insulation allows the house to heat up in minutes. I would highly recommend this company for price, professionalism and a job well done. Thank you so much for your excellent service mentality. read more

Our experience with Insulation Co was excellent every step of the way. We needed to have our attic and crawlspace cleaned, sealed, and re-insulated after a rodent infestation. Jo responded to my request for a bid within hours and came in well under the other bids we had received. I appreciated his low pressure sales pitch and his approachability via phone, text, and email. He was able to schedule the work quickly, and his team showed up on time and performed excellent work, communicating diligently about the process every step of the way and troubleshooting small issues they found. They worked quickly and efficiently and cleaned up the job site in a way that left our garage cleaner than when they arrived. The end result is a clean, sealed, insulated house above and below, and less quantifiable but just as important peace of mind. I am highly satisfied with the work Insulation Co performed and would recommend their services to anyone in need of such work. read more

Responsive and accommodating, the work was supposed to take two days, but they were able to send more than one crew to get the work in a single day before the holiday season! read more
