"I was absolutely content with the work that C&G Plumbing completed at my property. They knocked out some sewer repairs for me and made the entire process, which could've been a nightmare, stress free and easy. I definitely would recommend them to any one. Dependable, Informative, Honest, and Fast."

"Friendly guy. Ice storm So he was delayed. He arrived as quickly as he could. The r part had to be ordered and once the repair was made things were fine but a slow leak developed in the wall. No one noticed until later. Sheetrock was ruined.Thankfully, the leak was in the garage so the damage was not in the house. He did repair the plumbing problem but not the Sheetrock."

"Trained water treatment specialist showed up on time and tested several parameters of my water. Was able to answer all of my questions without giving me any pressure sales techniques. I learned things about my water that I had never even thought about before. Will have to go with these guys when I can afford the system, they definitely know their stuff."

"They did a great job! It went faster than I expected. I asked one of the guys if he had time, would he check a leak under my kitchen sink. He was very thorough. It turns out that we had a bolt still attached underneath the sink from a previous water filter installation. We needed a different type of bolt and he switched the bolts for free! He even gave me some much needed advice to help prevent further leaks from the faucet area. I really appreciated the extra mile! I am very pleased with Lone Star Water Services and would gladly recommend them to others."

"The services and work that Francisco Albaran offers to his clients is outstanding, extremely professional, respectful and friendly! I had a problem with my water heater and my plumbing in one of my showers. He was able to fix it and complete it thoroughly, which other companies couldn't and seemed like a big problem, he was able to do it! The service was quick, easy and inexpensive. You can't go wrong with it! Highly recommended !!"

"Personable people with excellent service. All services were done as promised. I took my chainsaw at a later date because it would not start. Nuts and Bolts guy got it started without any repairs. Called and said no charge. Great, honest service .

"I don’t usually write reviews but I felt it necessary this time. Calahan Construction has come through in the clutch for the second time with my A/C repair. (2 different houses) From here on out Calahan Construction will be my FIRST call. I tried to give opportunities to friends of friends and gotten burned both times. Each time Mr. Calahan has come through to clean up their mess! In both situations previous repair companies offereoptions of new units or extremely high price repairs. Mr. Calahan provided me with pictures and a detailed explanation of my problem and did repairs at a fraction of the cost! Extremely professional and efficient service! I would HIGHLY recommend this company to anyone in the DFW that need a/c work completed!"
