"Paul and his crew did a great job with the asbestos removal in my den. I was able to get on the schedule in a sufficient amount of time which was great for me because I was getting ready to have surgery and wanted to have this done prior to my surgery. They showed up in a timely manner, were polite, and cleaned up efficiently before they left. I would highly recommend S&P asbestos!"

"Alfred from SS John & Marin Restoration went above and beyond the original mold remediation job parameters and took care of additional remediation issues discovered in unexpected areas. He and his team did a superb job of remediating several mold issues, identifying underlying causes, and implementing strategies that would help prevent problems in the future. Alfred proved to be highly expert, doing thorough and excellent work, and freely sharing useful advice with me as homeowner. The expanded remediation job was completed at a very fair price. I would definitely recommend Alfred and SS John & Marin Restoration for any mold remediation challenges."

"I thought he did a good job explaining what he did do but very disappointed they didn't explain that you had to pay a lot extra money to actually find out what kind of mold if any you had. The $199.00 fee they only looked for mold & tested the air quality. If they found any mold it cost a lot more to find out what type. He did say we had mold in our crawl space but not what kind, that cost more money. Overall good for what he did do."

"I received various quotes from different companies for a radon mitigation system. RTE's price was not the highest and not the lowest but their customer service was excellent and was ultimately the reason I hired them. Brian came out and walked me through the quote process and Scott did an excellent job installing the system. I would recommend their services."
