"I had a rough experience when I found out a home we just purchased had water coming into the crawlspace. We had a long period without rain and the inspection didn?t show anything. I called a few companies out, but Cdg stood out to me. They replaced our gutters, fixed our flooring and cleaned up and fixed our crawlspace. I?m very pleased with their work. Will was very helpful."

"On 3-4 November 2025 Chris, Corey and Xzavier encapsulated my crawlspace and set up the dehumidifier for the electrician. Keep in mind, the crawlspace varied from about four feet to two feet. At two feet they were crawling on their bellies. The three arrived at my house on time, Chris explained exactly what was to be done and the three of them completed the job in a most professional manner. I inspected the crawlspace when the job was completed and was amazed at the workmanship that was done. I commend Chris, Corey and Xzavier for their excellent work and the courtesy shown to my wife, myself and even our dog, Zoe. Thank you, Chris, Corey and Xzavier for a job well done. "
