"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system.

"Came out in the middle of a flash flood warning and rain storm. Remediated the problem at an affordable price. The project required further work at a later date."

"Very friendly, showed up a couple hours after I called, to unclog my kitchen sink. Explained everything and very reasonable! Highly recommend!!!"

"F. H. Furr did the tasks I requested. Two tasks required the lighting be replaced."

"Mr. Bamford is an amazing gem. We have hired him repeatedly for different projects, and he ALWAYS goes above and beyond. Whether it's working over 15 hours straight to make sure we had hot water for the next morning, pricing out all of the alternatives to get us the best deal, or just popping by when we call to check out the issue and see what it will take, his service is above any provider I've ever worked with. I highly recommend him, and am grateful for the excellent service he provides."

"Honest and upfront about what really needs to get done. Another company had bid that was 10 times higher, though included a lot of water purification stuff that isn't needed."

"It went well. The install was done in approximately 3 hours; knowledgeable technicians. Our drinking water tastes amazing and resolved hard water problem."

"I met Jeff at my daughter's house to have several things done: replace her ultraviolet bulb, replace her water filter, hook up her water softener (she had recently purchased her home), and her washer needed the P trap put in which she had purchased. Jeff did all those things and checked her well system (the tank needed air). I was so pleased with Jeff's work and so glad there is an Angie's list! I had an appointment with a water treatment co. to change my ultraviolet light and cancelled it. Jeff came and changed the bulb, checked out my water softener, and put air in the water tank (which was not done ever by the repair guy from the water treatment co. I've used for years). Jeff listed things that would need to be replaced on the well gauge and switch and softener down the road. My husband appreciates the pressure in the shower! Excellent work. Considering the water conditioning guys charge $196 for only changing the bulb, we will definitely use Jeff's American Clean Water each year."

"I’ve had many water related issues over the last few years as a homeowner and also as manager of a restaurant. They can handle any plumbing task out there. Redline has always been reliable, fair & honest. Customer service and response is top notch! 10 out of 10 experience every time."
