"Continental Remediation Services provided incredible service when our office flooded and needed immediate attention for moisture control and mold prevention! Dean and his crew showed up within the hour and got right on the problem. They were very knowledgeable and answered any questions we had. Their pricing was great and very fair especially with us being a non-profit! Dean was so honest and definitely a trustworthy resource who cares about his clients! They not only treated the flood right away but also removed all of the damaged carpet and baseboards to ease our worries. I highly recommend Dean and his crew for any emergencies and home related work!"
