Get matched with top tankless water heater installers in Marriottsville, MD

"Vince told me outdoor spigot could be repaired and did not need to be replaced which saved me money. He also replaced a vanity faucet which I provided. He was quick, efficient and honest. The most important thing was he discovered a serious problem with the way my water heater was vented. The exhaust pipe had been cut wrong and glued together. It was ready to come apart and could have vented carbon monoxide into the basement. (We do have CO detectors but this is still scary) We had this water heater installed a couple of years ago by another well known local firm that I don't know if I can name here. It did fail inspection by Howard County 3 times after initial install. Failure was all related to the vent and probably should have never passed. Anyway, by pure luck it was discovered and fixed. Thank you Vince!!"

"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.

"Very professional service and reasonably priced water system installed in my house. Installed a whole home filtration system to privide continous purified water through the home. Highly recommend!"

"When I bought my combo tankless boiler/hot water heater, the original installers messed up installation, then couldn't figure out how to fix it. Thank god I found Rod. He fixed their mess, installed a sediment filter that's been super effective, and recently helped fix a venting issue caused during a remodel. He knows his stuff inside out, is fast and efficient, and a real pleasure to work with. Would absolutely recommend him for anyone with on-demand water systems."

"We needed to replace a toilet, James went with us to Home Depot to select one. We now have a water efficient and higher seated toilet, which is great for aging relatives that can’t bend so easily anymore. I would definitely hire/contract him again!"

"This was not an emergency repair, we were fortunate to be able to schedule the replacement about a week in advance. Heil sent an estimator to look at the space and make a recommendation. We originally wanted a Hybrid system but they advised against it given the space and need to collect/vent moisture. We selected a 75 gallon electric water heater. On the scheduled day, They were on time, removed the old water hearter and installed the new one - professional and courteous the whole time. Unfortunately, the new heater leaked the same day. They returned and made a temporary patch until they could return the next day with a replacement part. They returned, replaced the part and after they left we found that the tank leaked again in another place. They returned the next day and before we could insist that we wanted a different tank (clearly an out of the box failure on this one) they said they would replace the tank which they did. Our first, second and third experiences with Heil were all great with customer service and technical expertise. The inconvenience of multiple extra days without hot water and having to be there for four visits was unexpected and unfortunate however Heil responded correctly and made it right. You can get the measure of a company not only when things go right but also how they respond when things go wrong. We would use them again."
