We specialize in water damage restoration, mold remediation, fire damage cleanup, crawlspace odor removal, vapor barrier replacement, and animal-related contamination. Our IICRC-certified technicians provide 24/7 emergency response with fast, professional service. We handle insurance-covered restoration from start to finish, including documentation and direct insurance communication. Whether it’s a flooded crawlspace, black mold, smoke damage, or musty odors, Rutman Restoration delivers trusted, high-quality results. Fully CCB-compliant, locally owned, and family-operated. We work directly with homeowners and adjusters to simplify the claims process and maximize coverage. Our team uses commercial-grade drying, dehumidifying, and air scrubbing equipment to ensure full mitigation and long-term protection.

"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!"

Radon Detection and Reduction questions, answered by experts

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness
