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.

Frequently Asked Questions About Water Treatment in Gaithersburg

Find clear, straightforward answers about our residential repair services, transparent time-and-materials pricing, emergency response availability, and service areas across Central Maryland.

A water softener specifically removes hard minerals like calcium and magnesium that cause limescale buildup and soap scum. A water filter targets chemical tastes, chlorine odors, rust, and suspended sediment.

Common signs include white, crusty buildup on faucets, cloudy spots on glassware, stiff laundry, soap scum that is hard to scrub, and dry skin after showering.

Maintenance involves checking and refilling salt in the brine tank every few months. Resin beds typically last many years depending on water quality and usage volume.

When properly sized by a licensed plumber based on your home’s peak flow rate, a whole-house filter will maintain full household water pressure without noticeable drops.
