Hired NWCrawl in Aug. 2026, due to a rodent infestation in my crawlspace which required removing existing insulation, vapor barrier, exclusion and re-insulating the crawl. I worked with Patrick the PM & Eric APM crew lead. The entire process was fast and thorough and communication was easy & very responsive. They take pictures every step of the way particularly the exclusion work. During the clean out and insulation the crew is also very conscientious about your landscaping & keeping the yard clean of debris. The crew discovered a slow leak under my bathroom which required a stop work process. They left that area uninsulated so a plumber/mitigation team could access the area. A month later and a new bath floor..I scheduled the finish work. In the mean time I had my annual furnace (located in the crawl) maintenance done and the tech noticed my condenser pump was detached from the furnace - which ended up pouring water on my pump and killed the pump motor. I first contacted the mitigation team since they also take detailed pics of their work. They had a timestamped pic of them first entering the crawl which showed the pump at an angle and its hose detached. I then spoke with Matan, NW Crawl owner, showed him the pic. I believed his the crew had accidentally bumped/hit the pump while removing / installing the insulation, since no one but these two contractors had been in my crawl. Based on our discussion & the photos, Matan with out question agreed to pay for the pump which is a great example of NW Crawls integrity as a stand-up company. I would highly recommend NWCrawlSpace. Their entire crew was great to work with. When the crew came out to finish the insulation they also cleaned out my sump pump which had quite a bit of insulation/dirt debris.
