"Excellent communication via text and email so you know exactly when your service technician will arrive. Tommy and Duncan were very polite and professional. They looked over the main water shutoff valve that I wanted to replace and then explained what they were going to do and how much it would cost. Completed the work promptly and cleaned up the work site before leaving. I would highly recommend DB's Plumbing and Drain!!"

"Had a leak in main water line. Collected estimates and methods in replacing the water line. I am glad I found The Water Line Group on the web in researching best methods to replace house main water line. After calling The Water Line Group, Geary came the same day to review best method to replace the main water line. What I liked about his estimate it included two methods with no extra cost and very reasonable compared to other estimates. Work schedule was set up less than a week. I was impressed by the crew led my Jamie. They successfully did the trenchless method from the original connection to the water meter with no disturbance to house,front porch, tree, scrubs and driveway. They have the pull water pipe method down to a high success rate. I highly recommend The Water Line Group."

"Great. Didn't need to cut drywall (this time). Repair was made to fix leaking. Experienced plumber cleaned surrounding area to remount and seal to house siding. It's much better than before! Would hire again to fix all plumbing issues. Great service!"

"Appleton Campbell just did a complicated 2-day gas furnace/AC unit installation attached our home. It was, probably, the most professional and well-handled vendor experience I have ever had, particularly with some complications that occurred due to things found after the old system was removed. From the sales process to the pre-project staff to the office staff who alerted me each time the crew was heading to my home, to the on-site crew of Mike W., Danny R. and Jake A., the experience was A+. Even when the one issue was presented, they came up with a solution and I remained confident they would. They were extremely clean and neat, during and after they were done. I did getting three bids for this and they were slightly higher than the others, but I felt more comfortable and frankly, I believe I got my moneys worth as they also had to fabricate and redo a complicated return and vent line, and they also moved the gas line, refrigerant line and other conduits/poles/switches to a more convenient area than with my prior (similar but older) system. In short, I felt like the value was there. They also included a Home Savings Agreement for one year and left me with a consolidated notebook of all relevant documents. Cheapest is not always better, and with all they did, the pricing was very, very close. I've known AC for years in the community, but only used them on a couple of occasions. I've become a huge fan and will use them again (I have other systems!)."

"Gary from The Pipe Doctor was amazing. As soon as he walked in the front door and I told him the bath shower faucet was leaking he said the cartridge in the shower handle needed to be cleaned. He knew exactly what the problem was and was very patient with me while I asked about other possibilities I had found on Google (which obviously makes me an expert). He just knew without a doubt what the problem was. He said if he could just clean the cartridge the price would be about half the cost of replacing the cartridge with a new one. I agreed to both options in case the new cartridge had somehow become damaged. Once in the bathroom, he was surprised that the faucet handle was brand new, it had just been installed within the last month. The plumber who installed the shower handle was not able to find the cause of the leak, I had called him when water leaked through the ceiling below after a shower. He just caulked around the chrome plate. Gary found the newly installed cartridge was clogged with pieces of pipe liner used by Fairfax Water. He pulled pieces out of the cartridge and then asked me to turn on the main water line for about 1 second to flush the line, I did this four times. After each of the first 3 flushes, he pulled liner out of the pipe. It ran clear after the fourth flush. The pieces measure from 1/2 inch to 2.5 inches long. He did not need to replace the cartridge as it had not been damaged. He suggested I contact Fairfax Water, ask if they had installed pipe liner recently in my neighborhood, and ask if they planned to flush the lines. He also suggested I ask Fairfax Water to reimburse me for the repair, which did but I would be very surprised if they agree to that. Gary said liner could still end up clogging other plumbing in my house, and this could be a problem for me and my neighbors for months, you just never know when the liner pieces will make their way through the pipes. Gary is a very upbeat, friendly, positive person. He explained to me every step of the way what he was doing, why, and what he found, as well as the cause. He said the problem was not due to something the last plumber did. I did send that plumber an email just so he would know what to look for if another customer called with a leaking faucet. I had called The Pipe Doctor several times before and once after Gary's visit. I am so forgetful, wish I remembered her name, because she was always friendly, courteous, and answered all my questions. I would like to thank her for all her help and patience. The Pipe Doctor is now my plumber, they are experts. Below is a link to a Fairfax County article on the installation of pipe liners throughout the county. [*** Link removed ***]"

"We turned our water back on outside after the winter and saw that water was coming through one of our walls. We figured it was a burst pipe. Juan Carlos came out and cut into the drywall and fixed a couple areas of pipe that had cracked during the freeze (we hadn't gotten all the water out of the pipes). He showed us where he was fixing the pipe and made the repairs and told us we could test the pipes again in a couple hours and to call him if we had any problems. I was impressed with his knowledge and professionalism. Furthermore, he actually stopped by a couple hours after he made the repairs unannounced just to check up on the repair. I was impressed by that. We saw that there was a third break in the pipe and he made that repair as well. This time, the repair held and our pipes were fixed. He even offered us $25 off his quoted rate for being an Angie's List member (without me asking). I would not hesitate to recommend his services in the future.
