Rob and crew from NW Crawl Space did full remediation for our crawl space and attic, after finding evidence of rodents (mice) in both areas. Removed old crawl space insulation & vapor barrier, replaced heat-ducts that were damaged, & vacuumed out attic insulation and debris. Sealed openings in both areas to prevent rodents from returning. Traps set, with rodent control plan. Highly recommended!

Northwest Crawl Space Services has been honest, professional, easy to work with, and has done excellent work on my home. I first approached the company looking for someone to reinsulate and clean out my mud room crawlspace-- it is an addition to the house and is open-air. Lior came by and noted that because NWCSS specializes in fiberglass insulation, they wouldn't be able to work on this part of my house, because it would require spray foam insulation to truly be rat and weather proofed. I really appreciated this up front honesty-- two previous contractors had given me bids to reinsulate with fiberglass, never mentioning the need for spray foam, and never saying that they wouldn't be able to do a proper job. I would have paid money to some other company for a shoddy, inappropriate "solution" if Lior had not filled me in. Lior even recommended some other companies to call that specialize in spray foam! After this helpful and informative experience, I knew right away when I discovered signs of rats in my main basement crawlspace that I wanted NWCSS to be the ones to work on the problem. Lior came by to check it out and did a very thorough inspection. His manner with clients is excellent-- I never felt like my questions were being dismissed. We set a date for a crew to come by to replace rat-infested insulation, remove the improperly installed vapor barrier, clean out debris, and reinstall vapor barrier to industry standards. The crew, Patrick and Chandler, were friendly, polite, and happy to answer questions. Savannah in the office has also been very friendly and quick to answer my questions regarding logistics and payment. Overall, my experience was excellent and I will re-hire NWCSS when it comes time to reinsulate and clean out my attic crawlspace.

Matan gave us a fair estimate for the crawl space re-insulation and screening, and the work was done promptly. I was pleasantly surprised when the final bill came in about 15% UNDER the estimate. It’s nice to deal with a company which has the integrity to pass those savings on.

Northwest Crawl Space is a trustful company to work with. They helped me install the French drain, replace the insulation and vapor barrier. Matan and his stuff did a great job. They will carefully protect your home when performing the job, clean the waste after the work is done, and come back to inspect if the work is good.

We had Northwest crawlspace come out to inspect our crawlspace and they identify a lot of standing water as well as rodent activity in the insulation. As a result, we needed a full clean out of our crawlspace and new insulation, vapor barrier, drain and sump pump. The crew was professional, friendly and fast. The work was extremely well done, we recently had them come out to check everything and the technician confirmed it was one of the best installs he had seen. I would highly recommend this company to anyone.

My experience with this company has been amazing. Lior (the owner) goes above and beyon every single aspect, super professional and always providing the best advice to avoid unnecessary expenses. They did the whole work in my crawlspace, sump pump, french drain, vapor barrier, etc... and results are great, 0 moisture. I would definitely recommend it.

Lior and his NW Crawl Space Services team were everything we expected in professionals! They were on time, neat, though, communicative, polite, did the job as promised and then checked back with us as promised again to ensure that the job was done!

I had Northwest Crawl Space Services remove all my rodent infested insulation and vapor barrier. They cleaned & disinfected my crawl and installed all new insulation and a sealed vapor barrier. The workers were very diligent and and skilled in their methods. I was given a quote up front and feel that I received a quality job that was worth every penny. I am beyond pleased with the company and would highly recommend them to everyone.
