"I highly recommend David and his company, Rutman Restorations. I had rodents in the crawlspace of my home and the insulation and vapor barrier needed to be removed and replaced. This was no small task, as I have a single story home which has a larger footprint than many two story homes. David and I agreed to an excellent price and timeline. At first I was a little overwhelmed because I could see this was going to be an all hands on deck process. David coordinated work with Summit Pest company regarding the removal of the rodents and even spoke with the HVAC company when we discovered water in one of the ducts. (Which has now been addressed by the HVAC company that installed the A/C). David and his crew went to work right away removing old contaminated insulation and then sprayed the crawlspace with an antimicrobial solution before installing the new vapor barrier and insulation. David always kept me informed as the work progressed. I was happy to see they were using respirators, specialized suits and other safety equipment during the process. The crew worked diligently, had a great sense of humor, they were respectful and kept a positive attitude the whole time. I’ve owned other homes, but this is the first time I’ve ever been involved in the restoration of a crawlspace. I knew I was in good hands with David, Nico, Ben, Nayla and their great crew. Thank you for all your hard work! Kudos to all of you!"
