"Larry answered my call and explained why we have no need to remediate what was safe in its present condition, notwithstanding the re-roofing we are about to perform on the house. In other words, although he could have suggested we engage him for some remediation work for which I apparently would have had no need, he was honest and talked me out of paying for something I did not need. Class act."

"We discovered we had mold in our home after we had a leak. Matt and his team tested our home for mold, then we completed the dry fog remediation treatment. They gave me post tests to show the mold has all been killed. They were very thorough everything went just as planned. Excellent job, I am very impressed!"

"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"I had a great experience with Quality Restoration. Adrian came out quickly to assess the mold remediation damages, explained everything clearly, and gave me a very fair quote. He started the work right away, which I really appreciated. The remediation process went smoothly and we received passing clearance testing results. Now they’ll be starting the repairs soon. Adrian has been professional, responsive, and easy to work with throughout the entire process. Highly recommend Quality Restoration if you need mold remediation or restoration work done."
