From the initial sales conversation, through scheduling and the actual installation, the entire experience was seamless and fairly priced. Vlad in sales was particularly great. He was knowledgeable, low pressure, and patient while I gathered other bids to compare. After looking around, Insulation Northwest still came out as the best option on price and value. The crew was incredibly efficient. They knocked the whole job out in a single day while I was at work, and everything was clean when they took off. The whole team was professional and easy to work with. If I have another insulation project in the future, they're who I'm calling. Highly recommend.

Representative was confident and work was done to the tune of $6000+. Periodically checked immediate area and had exterminators down there bi-monthly with reports of minor moisture but overall OK. Orkin sent out a guy to perform an inspection and he reported the exact situation I paid to resolve. It was beyond 1 year but it is obvious they did not perform work I was promised. I asked them to honor the warranty 22 months after work, which I do know is beyond, but it is clear that they did not do work promised and I believe they should back up their work.

Great company. We originally just wanted insulation blown over what we had, but decided after…read moreseeing the amount of dirt, old animal debris, missing insects and lack of sealing of holes and areas we would have it all removed and replaced. $$$ but so well done! I went up and checked before, during and post work and we are so pleased. We are now properly vented and have airflow, have all areas sealed, vent fans sealed correctly and enough insulation. It took only about an hour for the estimate, including the 1/2 hour the gentleman took to write it up and provide photos, work to be done and costs (in a color pamphlet!). He also reviewed what was found and what work should be done and why. We were really impressed. The actual work was scheduled week later and took 2 days (did not take an entire day each day). They were quick, clean, put up plastic barriers to protect the walls, house and floor. No leakage of any debris or old soiled insulation occurred. 10/10 would hire again. Note: they took care if the PSE rebates and were recommended by PSE.

The proposal I received included several additional services that I did not request. I simply asked…read morethat those items be removed so the proposal reflected the scope I originally asked for. The proposal itself already included a clause stating the work would be considered partial remediation with no warranty attached, so liability concerns had already been addressed in writing. Instead of adjusting the scope, the company withdrew the proposal and sent an email suggesting my request to remove those additional items were "demands." Based on my experience, be very clear about scope and expectations before requesting a proposal from this company. They will scope creep on you.

We needed to clean up our crawlspace because we were having a rat problem down there. I had a few…read morecompanies come over to take a look and give an estimate, but we decided on Northwest Crawl Space for these reasons: 1) Matan came and was very knowledgeable and professional. I also found that he was the only one who wasn't "sales"-y in his approach. 2) Financing was an option with 0% interest if paying off in 18 months. 3) Was the most affordable out of all the bids. Don't get me wrong, the pricing was comparable, but this company won by a small margin in costs. 4) They provided the removal of items and trashing it into the costs. A particular company was going to charge an insane additional amount to do this. 5) The workers who came to do the work were all friendly, professional, clean and quick. They did the job of about 1500 sq. ft. of crawlspace in one day. 6) When we inspected the finished product the next day, we were happy and their work exceeded our expectations! No more crazy smell coming from the vents and everything down there has been sealed and re-insulated, so no vermin should be coming in. 7) Plus, they have a 1 year "Rodent protection plan" for someone to come every 3 months to monitor the rodent traps to ensure us that the rats are not coming in. So by these reasons, I highly recommend this company! I will update in a few months or a year to make sure we are completely "rodent-free" down there. Excellent job!

Other quotes I received varied in pricing by double and wanted 50% upon signing then 40% day of installation leaving 10% at completion. Also changing the installation date was costly, some $500 just to change a date. WA Evergreen did not charge a fee to change a date, nothing down just pay when completed. Great communication by all involved. I'm very happy that I chose them.

Pro's - Basic work seemed to be done well and at a price that was competitive with others I contacted at least for the basic service. - Communication was prompt. - After some re-scheduling on their part, the team did the work swiftly and efficiently. - Most of the terms were clear in advance, using Yelp Projects. Con's - This is a fairly shiesty corner of the home maintenance world. Many providers seem to give you a low-ball estimate to get in the door and then upsell significantly. - Envirosmart is not an exception. - The initial quote was $200. This included scoping the ducts and doing the negative pressure clean-out. - Onsite, they then upsold me to $670 for a more thorough brushing of the vents, sanitation, and some other ancillary services. - They were only modestly well-organized. They called the day-of to reschedule because of a conflict with internal training. They also confirmed a different time than I had originally scheduled. It was the difference of a 9 to 11am original window and a 2:30-3pm arrival. - The Yelp Project communication could have been clearer. They did not specify whether they were calling to quote me or coming to do the service! Amid all this and with some clarification and flexibility on our part, we worked it out. I would have appreciated either a discount or additional service for the delay. None was proffered. I did not go ahead with the upsell as I had already gotten quotes for less from other providers with somewhat more transparent pricing. I think the work they did appeared fine. See attached pics. Your guess is as good as mine which are before and which are after! They did not specify when they sent them to me and email took off the timestamp. I'm hoping the cleaner ones. I probably will try another service when I do this again and with a higher rated provider. All in all, though, I had low expectations and those low expectations were met.

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.

We recently had a rat in our attic and called Attic Crawl. From start to finish, Alex and his crew…read morewere very professional, friendly, and incredibly hard-working. While inspecting the rodent issue, they also discovered mold in our attic. Alex provided many photos to show us the issue clearly. Alex was very careful to explain the entire process at the start of it so that there were no surprises during the process. They ended up removing all the old, contaminated insulation, thoroughly sanitized the attic, replaced with new insulation and wire mesh around the entire perimeter where any openings might exist. They effectively excluded all rod ents or pests from the attic. Alex came back for a follow up inspection and verified the attic is now vacant. Quality Workmanship: Even our electrician, who went up after they finished to check to see if the rats had damaged any wiring, commented on how clean the attic was and what a great job they had done. Cleanliness: I was worried about dust and debris coming from the attic down into the living areas of the house, but they created a plastic barrier Between where they were working and the living areas that left our home spotless when they were done. The crew was courteous and focused throughout the entire process. The price was very reasonable and fair. If you need attic services or pest remediation, my wife and I highly recommend them!

WARNING: "R-49" promised -- measured ~8-14.5" -- dispute escalated to lien + court…read more I hired Attic Crawl Inc. for attic work including R-49 blown-in insulation (stated in writing). I trusted their proposal -- and I regret it. After the job (9/27/2025), I measured insulation depth in multiple locations and found ~8 to 14.5 inches in many areas, uneven coverage, and no depth markers. I shared photos/measurements and asked them to bring the attic up to the promised R-49. Instead, they said the attic was larger than estimated and would only add insulation if I paid ~$1,472 + tax. I obtained a third-party correction bid for $2,917.20 to air-seal and bring the attic to R-49 with depth markers, indicating additional work is needed. Because they would not correct the insulation without extra payment, I withheld final payment while trying to resolve the issue in writing. After that, the situation escalated into a small-claims filing and a mechanic's lien (which I dispute). Regardless of how anyone views the dispute, the result was this: a homeowner raised a documented workmanship concern, asked for correction to what was promised, and ended up dealing with court + a lien. Bottom line: I do not consider this a reliable company and would not hire them again. If you're considering Attic Crawl, protect yourself.
