Water Heater Services for Your Home

You don't think about your water heater until something goes wrong — no hot water in the morning, lukewarm showers that used to be hot, a puddle forming at the base of the tank, or a unit that's making noises it never made before. These are signs the system is either failing or already past its useful life. Most tank water heaters last 8 to 12 years, and the decline usually happens gradually enough that you don't notice until it stops working entirely.

James A. Douglas Plumbing installs, repairs, and maintains both standard tank and tankless water heaters for homeowners across the Greater Annapolis-Bowie area. Whether your current unit needs a repair, you're replacing an aging tank, or you're upgrading to a tankless system — we'll walk you through your options, what they cost, and what makes sense for your home. We're licensed by the State of Maryland, back our labor with a two-year warranty, and offer same-day service when you're without hot water. Contact us today for an expert and comprehensive estimate!

Why Choose James A Douglas Plumbing and Gas Fitting Image

Water Heater Installation

A standard tank water heater typically lasts 8 to 12 years. When it starts leaking, producing rusty water, or failing to keep up with demand, it's time for a replacement. James A. Douglas Plumbing handles full water heater installation — removing the old unit, connecting supply and discharge lines, and making sure the new system is up to code and running properly.

Tankless Water Heater Installation

Tankless systems heat water on demand instead of storing it, which means lower energy costs and a virtually unlimited hot water supply. But the installation is more involved — it requires proper gas or electrical supply, venting, and flow rate sizing for your household. We install tankless water heaters and make sure the system is matched to your home's needs.

Tankless Water Heater Repair

Tankless units are reliable, but they're not maintenance-free. Error codes, ignition failures, fluctuating water temperature, and mineral buildup are common issues that need a technician who knows these systems. James A. Douglas Plumbing diagnoses and repairs tankless water heater problems on-site for all major brands.

Tankless Water Heater Maintenance Services

Scale and mineral buildup inside a tankless unit reduces efficiency and shortens its lifespan. Regular maintenance — typically a flush and descale once a year — keeps the system running at full capacity and prevents expensive repairs down the line. We provide routine tankless water heater maintenance for homeowners across the Annapolis-Bowie area.
