It was a small job to blow insulation in our garage ceiling; I was concerned about being left with a dusty garage, so I hung painter's plastic to contain any mess. Though it was probably a good idea (I can be a neat freak)-- the guys worked very methodically to control excessive dust and debris. They cleaned up when finished and left the space very clean for the kind of work being done. They charged a fair price and I would absolutely use them again if needed.

In short I'm so happy we found these guys. They're fast,…read morefriendly, and totally capable. Best of all, their bid was less than half anyone else's. Just who you want to support. They do more than installing insulation--they also repair damaged installs, including ductwork and other stuff that typically surrounds insulation. Great for far more than just installs. In long 7 years ago, a contractor we hired neglected to hook up a drain pipe properly in our crawl space. We had to chase him and chase him and chase him to finish the work we could see, which he eventually did to a decent quality level, and cut the final price somewhat to make up for it. But we did not know about the drain pipe, since we didn't check under the house. Over time, the spillage damaged insulation, ductwork, and the visqueen lining the ground. Once we got the drain pipe fixed, we took several bids last week for the damage repair. Arrow came highly recommended by others in the trades. Jason stopped by on his way home from other bids--same day I texted him. Can't be more responsive than that! He was pleasant, friendly, informative, everything you want. He was very clear that their bid would easily beat the others, even without knowing what the others had bid (he gave me a ballpark estimate that came true 100%). He volunteered to take cat litter back under the house to soak up standing water. At that point he didn't even know he had the business, but as soon as he came back up I let him know we'd be hiring them. Their office was ready to schedule the guys any time we were, but Jason recommended letting the space dry out for a few days. This morning, Francisco and José showed up not only on time, but early. Both as cheerful and communicative as Jason, and they got to work even faster--one of them was trimming Visqueen before we even finished going over the work, and they hopped right down through the trap door and got after it. They fixed the duct, insulation, and lining in a couple hours, never even disturbing the house cats and pooch. They were super quiet and efficient. This house was almost 30 years old when we bought it, and we're 7 years in now. This project was a self-inflicted one, since we hired an idiot contractor when we got here. But finishing this puts us more than 70% of the way through our to-do list, and only one of the remaining projects is at a level of priority 1. Arrow helped us a ton and puts us another leg up toward getting this place ship-shape.

While some of the wooden plugs used were installed carefully and perfectly, a significant number of them were NOT, even though my concerns about visual impact had been made quite clear.

If it had been possible to hide these plugs under temporarily-removed/replaced siding, I would have given this company 5 stars.

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.

Our primary reason for choosing Northwest Crawl Space Services was their ability to provide a comprehensive, one‑stop crawl space solution. They offer the full spectrum of crawl space restoration services and can also install a sump pump system. We also used their high‑quality rodent prevention services as part of the project. Among the companies AI recommended to me, Northwest Crawl Space Services stood out with exceptionally strong customer reviews. I also browsed through some customer reviews, including a long, thoughtful one written by an older gentleman. He wrote, "Lior was our lead person for questions and he made it easy to understand, going over everything--I mean everything!" Lior is also the blogger who wrote the educational articles and the detailed, highly informative work logs on the company's website. And as luck would have it, the company assigned Lior to do our estimate. Now we can say the same thing: everything became easier because Lior stepped in with such calm, steadiness, and responsibility. On the day of the estimate, Lior told us they would protect the laundry room and the garage, and that they would do their best to complete the project to a high standard--he even said they would make our crawl space "beautiful." Our only expectation for the crawl space was basic functionality. It is technically part of the house, but the last time I went inside was thirteen years ago. This time, however, when I entered the crawl space to take photos, I had to admit that their attention to detail was truly impressive. I'm posting a few photos here--this is only a small portion of what they accomplished. The quality of the work far exceeded anything we had imagined. Considering the hours they spent in that low, dark, cold, and damp environment only deepened our respect for their perseverance. During those two days, even though the work was physically demanding, we could still feel that they were genuinely happy. This speaks both to their inherently positive mindset and to the healthy, supportive workplace culture within the company. The office staff were equally enthusiastic and provided the same high level of friendly, professional service. NWCSS is a company you can truly trust. A few days later, on a sunny afternoon, I went back into the crawl space. What I saw made me finally understand what "beautiful" truly meant. I sat there quietly, watching the interplay of light and shadow between the new floor insulation and the new vapor barriers, with the new air ducts weaving through the space in graceful lines. In that moment, the present felt eternal. Lior delivered on everything he said he would do. Highly recommend!
