"Great company. We have used them for over 20 years and they have always performed well. Recently, we installed carpet in our basement and this made the A/C condensation pipe too short. We did not notice the situation at first but found out later that the water had soaked that area of carpet. We went into a panic and called GAC. They sent a tech out right away and solved the draining problem. Always prompt and professional, one of best contractors that we have ever used."

"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."
