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!

Insulation Co gave me the best price out of all. The owner, Jo, was very knowledgable and easy to talk to.

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.

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.

TL;DR Finish quality was rough, seams and vents had heavy…read moreadhesive buildup, and several areas now collect rainwater -- and these concerns were never addressed. On top of that, the contract copy arrived 5 days late after a $2,000 deposit, the office initially had no record of our project, the written contract didn't match what we were told, and the job required three visits -- which altogether felt very unprofessional for a $6,000 repair. - We recently hired Guardian Roofing to repair a roof leak above our dining room. The inspection took place the week before Thanksgiving, and the repair itself was carried out on Thanksgiving Day. We genuinely appreciated that the crew was willing to work over a holiday. However, the weeks that followed involved multiple return visits and repeated attempts on our part to resolve concerns privately. Because these issues remained unresolved for nearly a month, we felt it was important to share our experience for future customers. Because water was actively leaking into our home, we moved forward quickly after the salesperson explained that the job would include replacing the roof plywood and installing a gutter downspout extension. We paid a $2,000 deposit that same day. Although the contract was signed electronically, we did not receive a copy for five days, despite being told it would be sent immediately. During that time, the salesperson became unresponsive -- and when we contacted the company office to follow up, they initially had no record that we had signed a contract or paid a deposit. That was extremely concerning given the urgency of the situation. After the repair was completed, we finally received the written contract -- and only then realized that it did not match what we had been told. The gutter extension was not included in the document, and the plywood had only been partially replaced, even though we had understood the replacement would cover the full section. When we raised these discrepancies, we were told that the company had simply followed the wording of the contract. Only after further discussion, including acknowledgment of what the original salesperson had described, did the company agree to install the gutter extension at no additional cost. Still, for a $6,000 repair, the overall process felt disorganized and unclear. The job ultimately required three visits: the initial torch-down installation, a later trip to add the omitted gutter extension, and then another visit to secure that extension after it was installed too loosely. Even after all of this, our original concerns about finishing quality and water pooling were never addressed. These concerns were not just about appearance. This section of the roof is clearly visible from our upstairs rooms and yard, and even neighbors who can see it commented that the work looked surprisingly rough for a professional installation. The seams and vent patches were left with heavy, uneven adhesive buildup, and in several areas rainwater now collects instead of draining properly. When we raised these issues, we were told that the work met company standards and, in their words, "we are not decorators." The conversation repeatedly shifted toward explaining the nature of torch-down roofing -- as if the outcome were simply inherent to the system -- rather than addressing the quality of the execution itself. What made the experience particularly difficult was feeling that our urgency and lack of technical knowledge were not met with clear guidance and follow-through, but instead left us to discover contractual and workmanship issues only after the fact. In the end, the combination of delayed documentation, unclear expectations, inconsistent internal awareness of our project, multiple return visits, and workmanship that appeared unfinished left us disappointed and concerned as customers. We hope this review helps other homeowners make informed decisions and encourages greater clarity, accountability, and care in both communication and work quality going forward.

Dishonest! They intentionally omit an important "requirement"…read more I requested an estimate for an exhaust vent repair which was simple to do on Guardian's website. Guardian quickly called me, which became a strange experience. The lady from Guardian asked me if my Wife was employed and what her hours were. I asked why she wanted to know that, and she replied that they like to be able to discuss the project with both Husband and Wife. I told her that I'd handle everything myself. She again started down the road about my Wife and asked what time she gets home. I said don't worry about my Wife's hours, she doesn't need to be at home for me to hear how much this will cost. Such a personal question, especially after having asked to stop, is very inappropriate and weird for Guardian to pose. An estimator came to our house a few days later; fantastic employee and experience. He was very professional and knowledgable. I went up on the roof with him and he explained a lot about shingles, etc. He was at our house for an hour. I received a message from Guardian the next day asking to schedule another visit to my home to discuss the estimate. I was confused by their request. I politely declined and asked them to email me the estimate like every other estimate we received. Guardian refused to send me my estimate. Then they emailed me: "Our process does require an in-person review the estimate so we can walk through the details, materials, and options and answer any questions. Since a lot goes into our estimates, we're not able to send the estimate by email alone." No, their "process" is something they made up; no one is making them do this. Yes, they CAN email an estimate...like all their competitors. They want to come out again to try and pressure us. Guardian is saying that I have to take time out of my day, again, to be presented the estimate in person. Their competitors came to my house, then emailed me an estimate the next day. Like every other estimate experience I've gone through in my life. Had Guardian told me they refuse to email the estimate, I never would have let you come in our home. But they intentionally didn't say that, a lie of omission. This is a deceptive tactic. It's also extraordinarily disrespectful of my time.
