"Cal Coast communication through the whole process was what I needed. I didnâ t know the questions I should ask. I was scared and nervous. Iâ ve never been through this before. Cal Coast took care of everything and problem solved for me throughout the whole process. Not only did he do the water mitigation and mold removal, I hired him to do the put back as well. Everything was done on time. I highly recommend them."

"The two gentlemen from Risk Free Serv were knowledgeable and professional. They worked well together and took care of my home as if it were their own. They found mold behind the bathroom vanity and kept me informed of the process as they removed the mold, vanity, and drywall. I appreciated that they didn't try to charge me for unnecessary services as some other companies did."
