Get matched with top water heater installers and replacers in Crownsville, MD

"What can I say, other than WOW! I first talked to the owner (Brian) at 8:19am to tell him that I needed a water heater replacement and I sit here typing this review at 11:42am after the job is done . What, a complete hot water heater replacement in 3.5 hours from the time of first contact? Who does that!? Technicians Sam and Joseph were top notch. Super courteous guys who know their trade. Price? How about $1000 cheaper than the Len the Plumber! Call Brian at Speedy Water Heaters/Modern Plumbing Systems, you won't regret it!"

"Saved by Ehrhardt Brothers Quality Plumbing (a.k.a ColumbiaPlumber)! (West of Baltimore) Our gas water-heater failed! It’s 30° outside! (Mar 2026). It was leaking, so we shut off the gas, the pilot, and the water inlet, to lessen damage if it burst. Ehrhardt offered a price based on our descriptions and photos, of course with caveats for anything unexpected. A water-heater costs a pretty-penny, but less than we expected. A fair price. They came the next morning, and had the water heater replaced in 90min. Impressive. But the manufacturer sent a unit with a bad pilot! Ehrhardt returned immediately and in 30min, they figured it out. They had a replacement part over-nighted. The next morning, in 30min, done. Hot water. AAAAAHHH :-) The problem was the manufacturer’s fault, and Ehrhardt handled it flawlessly: Excellent communication by Ehrhardt, priority attention to our problem, no excuses, just fast resolution. Great service staff. Perfect!"

"Hired Mahon Plumbing to replace a toilet at my moms house. Chris and the technician were knowledgeable and responsive. I had a great experience working with them and would hire for any future needs."

"Installation went very well. Oct 25: Rob Figliozzi came out to evaluate the work needed and brought two workers to install the sink faucet and drain/trap. He determined what parts were needed for the tub/shower and ordered the parts. He texted me when the parts came in 3 days later and Chris Hanes came out to install. Chris is a very pleasant young man and did a great job with the installation, and Rob was very helpful and responsive. Highly recommend."

"Changed the brand of heat pump to be installed 24 hours before installation with no prior notice."

"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. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"Prime Plumbing provided excellent customers service from the beginning to the end. Rob was very thorough when he came out to provide estimate, financing options and gave good explanation of what was needed to replace my direct vent hot water tank for my condo. Rob was also the one who installed the hot water tank and did an excellent job. Direct vent hot water tanks are much more expensive than your standard hot water tank, so it was pricey. I initially found Prime Plumbing on Angie's list and I would recommend them for your plumbing needs. I'm a single female in my early 60's. I did end up using my own financing because their finance company interest rates were way too high for someone with excellent credit. Do rate comparison first."
