We’ve been proudly supporting the Baltimore-metro area for over eight years. From minor leaks to major mishaps in both residential and commercial properties, we can address all your plumbing problems. SJT Plumbing has created longstanding, trusting relationships with customers throughout Maryland. Give us a call today.
"The service tech came to my home and did an assessment of the issue. Found the leak in the gas line, showed me where it was leaking. He told me what needed to be to fix the leak, gave me a quote, got his tools and started working. The whole process took about 30mins or less and he was done. I checked my burners to make sure the gas was flowing properly. Everything was put back in its original place and there was nothing to clean up afterwards. Great Job. I would recommend this company again."

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!
"I’ve used Len the Plumber in the past, but after today, I will never be using their services again. I called to follow up on a recent (and expensive) drain repair - work that my family stretched our budget to afford. The plumber who came out was great: professional, kind, and respectful. But unfortunately, the drain is still not fully cleared. When I called customer service to ask if there was any warranty or guarantee on the repair, I was met with nothing but attitude. I wasn’t rude, I simply asked a question. Rather than receiving a straightforward answer, I was spoken to in a condescending and dismissive tone, as if I didn’t have the right to inquire about a service I paid a significant amount for. If the answer is “no, there’s no warranty,” then just say that. I would’ve scheduled another appointment and paid for the additional work. But I refuse to support a business that treats its customers like that over the phone. I hung up and blocked the number. To whoever runs this company: please take customer service seriously. It’s hard enough to pay steep prices for plumbing work—being treated rudely on top of that is unacceptable. Hire people who are kind and respectful to your customers. You’ve lost my business."

FAQs for water heater service projects in Severn, MD
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.
It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.
It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
