Frequently Asked Questions

Emergency Plumber Basics
Benefits of Accurate Water Leak Detection

Emergency Plumber Basics

As the name suggests, an emergency plumber refers to a plumber that specializes in handling emergencies. Things like burst pipes and seriously backed up drains are part of any good emergency plumber’s list of services. The trick for customers is to find an emergency plumber that is available when you are having a plumbing emergency. Much of the time, you aren’t thinking as clearly as you normally would, so you may end up calling any plumber that will come to help. Find your ideal emergency plumber before you have an emergency, so you can pick up the phone with confidence and get the best possible help when you really need it.

Benefits of Accurate Water Leak Detection

A hidden water leak in your home can cause immeasurable damage, which is why you should always call a plumber as soon as you see signs of moisture that don’t belong. Even if you aren’t sure where the leak originates, a plumber with water leak detection experience will be able to find it and put a stop to the damage quickly, saving you money.

What Our Clients Say

Gene Johnson plumbing installed a new toilet for us, it was great working with them! Ishmael gave us estimates for various options, and we decided to buy our own toilet and have them come back to do the installation. Krystal did the install, and she was clean, efficient, very pleasant to work with, and the job was done quickly! It was also easy to schedule the work to be done. I would definitely work with them again!

– Lisa Henry

Another exceptional service call!…Alex was a true expert and he was very thorough and was patient while we went through our list of plumbing goals during this thorough full house inspection. He was able to give us some cost estimates on the spot. I certainly feel like I’m in the best hands and look forward to moving forward with our project.

– Ivan Archer

I had a new water heater installed with Gene Johnson this week and I was very happy with the whole experience. Eric Sams was my technician and he was incredibly knowledgeable and friendly and really took the time to explain my options to me. We have “unique” water heater systems in my place and he really knew what he was doing, I knew I could trust him. The installation was scheduled quickly and works/looks great!

– Ashley Curtin

Great experience with Branson! Very friendly, knowledgeable, and the quote was accurate. Needed shut-off valves installed on my house from the 40s, existing lines were galvanized steel, so that made things tricky. He outlined several options and recommendations, and we settled on something that will be compatible and easy to work with for future kitchen remodel plans. Will definitely be calling Gene Johnson again when it’s time to do more plumbing work!

– Brian Munn

I reached out to Gene Johnson regarding my radiant heating not working properly. They were able to come by within the next day to take a look. Tech Mike F was very knowledgeable and honest regarding next steps and questions my wife and I had. We proceeded to replace the Manifold and add a magnetic separator to my unit. Heat is now working! :)

– Phil Maaa

Prompt, informative, professional, friendly – very happy with service today.

– Francy M

Carlos was terrific!  He had the necessary parts on hand – he explained the problem, the solution, cleaned up after himself and now I don’t have water dripping under the sink!  Thank you Carlos!
