Review 1
I did not know I needed a friend in the insulation and crawlspace industry, but now I have a team of them in Northwest Crawlspace Services. Only good things to say about the experience with Lior and his team. Lior was on time, honest, kind, he welcomed all questions and was very thorough in his explanation of the process. My crawl space was only partially insulated, badly done at that, tiny, old and well, gross! Matan came in, cleaned everything up, insulated everything, insulated the pipes, sealed gaps and installed a new vapor barrier and left the palce cleaned up like he hadn’t even been there. Now my tiny crawlspace looks brand new. They work with PSE for rebates and that was seamless! A small hiccup was fixed quickly and I really appreciate the follow up inspection. My pipes will be safe next winter and already my home is warmer!

Lior and his crew were great! They were professional, on time and cleaned up after the work was complete. They have followed up several times to make sure the crawl space is still free of critters and even reinstalled some insulation that was removed due to an unrelated plumbing issue. I would definitely recommend them and I’d give them 5 stars!!
