They shuffled around a few things to make sure my restaurant was able to stay open! We will use them again!Posted on CAYLEE C.Trustindex verifies that the original source of the review is Google. Grant installed our water heater a few years back, so I called him when we needed work done recently. He is very knowledgeable about the work he does, and he likes to make sure you are good to go before he leaves! One thing I would recommend, as with any company, make sure you are clear on pricing and what your quote covers.Posted on Victor CrappsTrustindex verifies that the original source of the review is Google.

We begin by shutting off the water supply to the existing toilet and draining the tank and bowl completely. We then disconnect the water supply line and remove the toilet from the floor. Before setting the new toilet, we inspect the floor flange carefully for cracks, corrosion, or damage. We also check the surrounding subfloor for any soft spots or water damage that may have developed from a long-term base leak. If we find damage that needs to be addressed before the new toilet goes in, we let you know and discuss the appropriate next steps.
Once the flange and subfloor are confirmed to be in good condition, we install a new wax ring seal and set the new toilet carefully in place. We secure it to the floor properly to eliminate any rocking or movement, then reconnect the water supply line and turn the water back on. We run several flush cycles to test the operation, check every connection point for leaks, and confirm that the fill valve and flapper are functioning correctly. We do not consider the installation complete until everything is tested and working properly.

If you have already purchased a toilet and want us to install it, that is completely fine. Let us know the brand and model when you call so we can arrive prepared with the appropriate materials. If you have not chosen a toilet yet, we can offer practical guidance on sizing and features based on your bathroom setup and household needs. We do not sell fixtures, but we are happy to point you in the right direction so you end up with a toilet that fits properly and performs well.
Toilet installation is one of those jobs that looks straightforward but has enough variables to go wrong when it is not done carefully. The wax ring seal needs to be set correctly. The toilet needs to be secured without over-tightening the bolts and cracking the porcelain. The flange condition needs to be checked before anything is set. Mueller’s Plumbing Service has been handling toilet installations in Goose Creek for over 30 years, and we pay attention to every one of those details on every job we take.
We work cleanly, we communicate clearly, and we do not leave until the installation is done right.
Yes. If you have already bought a toilet, we are happy to handle the installation. Just share the brand and model information when you call so we can arrive with the right materials for the job.
A standard toilet replacement typically takes one to two hours. If there is floor flange damage or subfloor repair needed before the new toilet can be set, the job may take additional time.
