We found an unexpected water leak, called Stang Plumbing and they responded within the hour on the same day. Jeff arrived promptly and was very knowledgeable and helpful. He got right to work and helped us start digging into the problem. The problem ended up being more complex than anticipated and we got extra help from John, who was also fantastic. They recommended a restoration company for us to work with and made sure we understood all elements of the issue. Very happy with the service and would 100% recommend or hire them again.![]()

This was our first time using Stang Plumbing for a problem in our upstairs shower - replacing an old broken diverter valve in an extremely tight space. To say we are happy with the results would be an understatement. Jason Morris, the plumber Stang sent over was not only personable but focused, professional and efficient. This is a guy who knows exactly what he's doing! To make things even better, the cost was by far the lowest from over a dozen calls I made to other services. We are "5-star" happy with the results! A huge shout out to the crew at Stang.![]()

Second time using Stang Plumbing & Heating and very pleased with their service! Jaison was very dutiful and polite. He took the time to explain things and was very knowledgeable and nice. His experience definitely shows. He got both jobs done in no time. Also, the front desk lady's reception was very pleasant and welcoming. This is a company run by and comprised of good, honest working people who value professionalism and transparency. (A rare find these days.) Happy to call on Stang Plumbing & Heating again and again =)![]()

During a recent major snowstorm, my water heater failed due to a blocked roof vent. I discussed my problem with Dawn of Stang Plumbing and John and Rob arrived the very next day to analyze / troubleshoot the problem. As a result, they formulated a plan to identify / remediate the problem. I’ve used their plumbing services many times in the past and I’ve always been very satisfied. They are all extremely friendly and very competent professionals. I would highly recommend to my family and friends!![]()

This is the fourth time over the years, that I have used Stang Plumbing. One time for a leak in the basement, once for a new kitchen sink and faucet install, with me supplying the faucet and the sink, another time for repair of a leak under the kitchen sink. And this time for a garbage disposal install, with Stang plumbing supplying the disposal. Each time they were responsive with an upfront price quote. Each time they arrive the next day as promised. All their personnel are polite and professional. Each time the job was done right and the technician left the job site neat and clean when they finished. I think their prices are resonable and competitive, and I do like that they have senior citizen's discount. Stang Plumbing will always be my first choice, when it comes to my needs for any plumbing work.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Keep your household infrastructure operating smoothly with our full line of specialized services:
Prompt diagnostics and reliable repairs for noisy units, low pressure issues, leaking pipes, or heating failures to restore consistent hydronic warmth.
| Feature / Consideration | Hydronic Heating Boilers | Forced-Air Furnaces |
|---|---|---|
| Heat Distribution Method | Circulates hot water through sealed baseboards, radiators, or radiant floor tubing | Blows heated air through sheet metal ductwork and room registers |
| Indoor Air Quality Impact | High; radiant heat generates no dust, dander, or allergen movement | Moderate; requires regular filter changes to manage dust circulated by blowers |
| Heating Consistency | Delivers steady, uniform radiant heat that absorbs into surrounding room surfaces | Creates faster warm-up cycles but can result in noticeable hot and cold air drafts |
| Expected Equipment Lifespan | Long service life, typically operating efficiently for 15 to 30 years | Moderate service life, typically lasting 10 to 15 years before major replacement |
Find clear, straightforward answers about our residential repair services, transparent time-and-materials pricing, emergency response availability, and service areas across Central Maryland.
With proper annual maintenance, high-quality residential boilers typically last between 15 and 30 years, outlasting standard forced-air furnaces.
Boiler sizing is based on a detailed heat-loss calculation that evaluates your home’s square footage, insulation levels, window count, and total radiator/baseboard capacity.
High-efficiency condensing boilers extract additional heat from exhaust gases before venting them outside, achieving annual fuel utilization efficiency (AFUE) ratings of 90% or higher.
Yes. Combination (“combi”) boilers heat water for both your home’s radiant heating loops and your household taps, eliminating the need for a separate water heater tank.
"Quality doesn't cost, it pays. We charge fair time-and-materials rates with clear honest cost guidance"
