Beis Plumbing is a family owned business with over 20 years of field experience in the St. Louis community! We pride ourselves on cleanliness, friendliness, and ability to remedy the task at hand! We are heavy in the new construction builds, remodels, and room additions (Basement finishes included)! Give us a call or text today for all your plumbing needs inside and out!! Thanks, Beis Plumbing LLC.

"What should one say about a company that would be willing to install a water heater without remedying an issue that would VOID THE WARRANTY? This is the case for an interaction I had with Beis Plumbing today. I called to arrange getting an estimate for the installation of a new water heater. I found that their standard procedure is to give a phone quote and no home visit. Admittedly, other companies have a similar policy. When I explained that an in-home estimate from another company identified a water pressure problem that could affect the longevity of the water heater and quite possibly result in a failed inspection, I was told that they could just add the cost of a Pressure Control Valve to the phone quote. I stated that I was not comfortable with simply getting a phone bid. How could an accurate quote be given without reviewing the location for the installation and other possible issues? But, I sent the 2 photos of the water heater that they requested. A short time later, I received a call from a Beis representative wanting to give me a quote for the water heater and installation. She was aware that I wanted an in-home visit and told me that they would require a $95 charge for such a visit. I explained that I am not willing to pay $95 for a quote that I may or may not accept. The call ended amicably and I crossed Beis Plumbing off of my list. A short time later, I received another call from a Beis representative. The guy said he was calling to give me a quote on the installation of a water heater. I told him that I had already spoken with someone from his company and I relayed the same information I gave to the previous representative. I also told him that I am not comfortable because if I had not known about the water pressure issue and told them, I would have received an unwanted surprise of a large add-on cost at the time of installation. It was at that point, he stated something that made my jaw drop. This guy had the audacity to tell me that I would not be required to have the water pressure issue resolved. Beis would still do the install. He then went on to state that WARRANTY ON THE WATER HEATER WOULD JUST BE VOID. I was flabbergasted that a representative of a company would tell a prospective customer that the company would install a product knowing that the warranty would be void. When I asked him why a customer would want a product installed knowing that the warranty would be void, he stated that he was ending the call. To me, this indicates a willingness to perform sub-standard work as long as they could point the finger at the customer. Would you want such a company doing work for you?"

I am a new branch off an existing company, small family buisness so you don't pay the overhead! 15 years experience, mostly custom design. All rough, finish, and service work done right the first time! I can help you design and install your dream bath or kitchen and with as little cosmetic damage as possible. I have a network of my own subs to help with any other needs such as custom tile, carpentry ect! You won't be disappointed! All work is guaranteed. 24 hour emergency service with no overtime rate, bill is due in full upon completion, partial payments after stages such as rough in. Have a great connection to provide fixtures and a show room to view them, owner can provide ther own products, all labor will remain guaranteed, however product shall be covered by supplier if other than mine!

"Joe did a great job and quickly too. While Joe was there he noticed the water pressure was too high (82 psi instead of 65 psi). He was able to replace our water regulator on the same call which also resolved several "leaky" faucets that were dripping do to the water pressure being too high. Had this happen about 15 years ago so I was glad Joe caught the issue. Also due to the over-pressure the pressure tank on my hot water heater was breached and full of water. Joe was able to replace it also while he was here saving us another trip. Joe was personable, professional, and knew what he was doing. Glad I called Beis plumbing and not someone else, even if it did cost more now everything is fixed and working properly. No more drippy faucets and a nice new water saving toilet. Win-Win situation"

Water heater 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.

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.
