"UPDATE: My previous review still stands from a couple years ago for that specific plumber only - but my most recent experience has been a nightmare. Will never recommend this company ever again. They definitely have changed since my last experience. Not only did the plumber they sent (12/9/24) not do anything to make any effort to clear a clog ( I won’t be petty and provide a name, even though I should) - after signing agreements and I asked if I should pay now -he said I probably should so he could get started - I know I should’ve just sent him on his way, but wanted to get this fixed (astronomical for what was -or in this case wasn’t done- and was told that prices had gone up a lot since my previous experience). He also had to inform me that normally they send the new guys to do this type of work ( implying unclogging drains was beneath his “expertise “). Then proceeded to tell me he was convinced it was a collapsed drain (after snaking the drain for less than a few mins)and that I probably had water flooding under the foundation said he needed to get a hold of their camera guy to be sure - he went to his truck to call him came back in, about 20-25 mins later to tell me he couldn’t get a hold of their camera guy and left a message for him. He then said he would try one more time with the snake - did the same amount of effort as the first time and said we would have to wait until he could get a camera down there and that we would have to let the drain dry out a bit so it would probably be the following week. Packed up his stuff and said I should call him in an hour to see if he heard from the camera guy (why should I do the calling for follow up??) When he left, he seemed to struggle backing out and damaged our lawn (have security camera footage). I called the company the next day and was sent to voicemail (left a message that said I had some concerns but didn’t leave a lot of detail) and was told that I should hear from someone that day - I did not. Called the next day and was told by the supervisor of the phone people that the phone person should have told me it was 24-48 hours before a manager would respond and she would not allow me to speak to anyone else. I did not hear back from anyone in 72 hrs, so I called back and then was told that the manager was out (conveniently). I gave up calling them and called another plumbing company who fixed the issue in a short amount of time (no collapsed drain, just a good ol’ clog). Decided to call Len the Plumber one more time ( 12/23/24) 2 weeks AFTER my original call and was told that there was a note in my file that said the mgr did call 3 days prior to this call (there had been no conversation or missed calls or voicemail received by me - so either he called a wrong number or this was a lie) and in the notes the mgr (Brian, I was told by the phone person)stated that I was told about the pricing and that was it. Not sure where he got his information of what he thought my issue was, since I didn’t leave a lot of info when I spoke to the phone people other than it was frustrating to be told I would get a call in 24-48 hrs. This last phone person said she would send an email to all managers with my concerns and would hope someone would assist. No response. (12/28/24). Think twice before using this company. It has changed ownership twice since the original owner- history has shown as ownership changes in companies , so do priorities and not to the benefit of the customers."

"Hot water issue. Technician gave estimate for hot water tank replacement of 8 year old lightly used tankless. In light of the phenomenol price tag, did some homework. Hit the reset button. Fixed. Hmmmm. Maybe it was the tankless that confused him. Really glad it was a free estimate (unlike Len's who charged me $315 and didn't fix it)."

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."

Boiler installation services FAQs
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.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
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.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
