Why Choose James A Douglas Plumbing and Gas Fitting Image

Kitchen Plumbing Services

Your kitchen runs on plumbing — sinks, dishwashers, garbage disposals, supply lines, and drain connections that all need to work together. James A. Douglas Plumbing handles kitchen plumbing installation, repair, and replacement including dishwasher installation, garbage disposal installation and repair, sink installation and hookup, and sink and drain repairs. If something in your kitchen is leaking, clogged, or not working right, call for service.

Bathroom Plumbing Services

Bathroom plumbing problems go from minor annoyance to water damage fast — a running toilet, a leaking shower, or a dripping faucet can cost you more the longer you wait. James A. Douglas Plumbing provides bathroom plumbing installation, repair, and replacement including toilet installation and replacement, toilet repair and clog removal, shower installation, shower leak and fixture repair, and faucet installation, repair, and replacement for homes across the Annapolis-Bowie area.

Water Heater Services

No hot water is one of those problems you notice immediately — and it usually means the unit needs repair or replacement. James A. Douglas Plumbing installs, repairs, and maintains both standard tank and tankless water heaters. Services include water heater installation, tankless water heater installation, tankless water heater repair, and tankless water heater maintenance. Whether your current unit is failing or you're upgrading to tankless, call for a same-day estimate.

Drain & Pipe Services

Slow drains, recurring clogs, hidden leaks, and aging pipes are signs that something needs professional attention. James A. Douglas Plumbing handles drain and pipe work including clogged drain cleaning, water leak detection and repair, backflow testing, pipe replacement and plumbing upgrades, whole-home repiping, sump pump installation, and sump pump repair. If water isn't flowing the way it should — or it's showing up where it shouldn't — call before the problem gets bigger.

Recent Review: "My experience with James A. Douglas Plumbing & Gas Fitting was nothing short of fantastic from beginning to end. From the start, they were very responsive to my emails and/or texts. They talked me through several possible remedies for me to try to resolve my situation before I made the decision to finally replace my hot water heater. There were no high pressure sales tactics or attempts to add on unnecessary parts or services. The technician, Zac, who came out to install the new hot water heater was extremely professional and friendly. He also took the time to explain everything in a way I could understand it. James A. Douglas Plumbing will be my go to for any future plumbing needs," --Josh Peters Thank you for supporting our company, Josh! We'll make sure Zac hears your praise!

Trivia on Tap: Happy President's Day! To celebrate, we're wiping away the grime on a tall tale about President William Howard Taft. It's been said that President Taft got stuck in a White House bathtub and had to be buttered out, but that’s actually a myth. In fact, just after his election Taft had a custom porcelain tub installed that was big enough to fit four grown men! However, while he never got stuck, he did cause a bit of a plumbing catastrophe two years after his presidency ended. In July 1915, Taft was staying at a hotel in Cape May, New Jersey and over estimated the amount of water needed for the tub. When he got in, so much water was displaced that it trickled onto the heads of guests in the dining room below! The next day as Taft looked out onto the Atlantic ocean, he was quoted saying "I’ll get a piece of that fenced in some day, and then when I venture in, there won’t be any overflow," From clogged tubs to leaky pipes, we'll be sure to make sure your plumbing can handle a 'presidential' soak! Just Call James to set up an appointment!
