Kamron texted to let me know he was on his way, he was very nice and polite. So far it looks like a job that is done very well.
We are just at getting the estimates stage of potentially replacing a main sewer pipe. Tyler from Service Force Plumbing was excellent. He patiently explained the video images as he was assessing the condition of our pipe. His assessment of the situation was based on his expertise. Unlike others we encountered in this process, there was no constant upsell or scare tactics to get us shell out thousands of dollars.

I had a simple bathtub clog that another company had completely overcomplicated, leaving me wondering if it could ever be fixed without extensive work, such as cutting pipes. Thankfully, Joe and Roy were calm, professional, and reassuring from the start. They put me at ease and assured me they could take care of the issue.
And Kamron was an absolute lifesaver! He was incredibly knowledgeable, professional, and efficient, and he left such a positive impression. It’s rare to find a team that combines expertise, honesty, and excellent customer service so seamlessly.

Erika Bauer5 reviewsiTotal number of Google reviews Erika has written across all businesses on Google Maps, not just this one.
Very pleased with the service from Service Force Plumbing. All the folks I interacted with to replace my water heater were incredibly professional and expert in the plumbing trade. The owner, Roy, spent quite a bit of time on the phone discussing options, which made his partner Hendrick’s visit the following day to gather information for the quote quite efficient.
Quote was a fair price and about a grand less than the other company we had received a quote from. The only thing that was missed (the other company missed it too) was that the closest outlet was too far away to plug it in without an extension cord. They recommended another incredibly professional electrician who provided a quote over the phone (rather than coming in person and charging for a visit) and was available to do the work the next day. And it was only a couple hundred more to do the required electric work. So even with that, still cheaper than the other company.
John, the master plumber who actually came to do the work, was also great - very friendly and professional too. He was very cognizant of where to place drop clothes to avoid a mess and cleaned up well afterwards. I was home during the work and so were my dogs, and he (and Hendrick, who came to provide the quote) were great with the dogs and communicated well about water being shut off and restored. He also spotted a couple of things that may be needed in the future and told me what to look for if the expected issues arose, with zero pressure to add that work to the visit before it was truly necessary. That certainly helped me to plan for future needs in an informed way.
Very impressed with this team across the board, and will be saving their contact info for the future. Definitely recommend.
P.S. this is a long review from someone who hardly ever submits reviews, which also speaks to the quality of the service - I was compelled to submit one because the experience was so smooth and unstressful even in an emergency situation that had least me without water.

Service Force Plumbing saved the day once again! I’ve used them several times for both my home and my rental property, and they’ve consistently been reliable, communicative, competent, and incredibly honest.
This time, my tenant reported water “flying everywhere” from the kitchen faucet. Service Force sent Tyler—my go-to person for all things plumbing—the very next day. I expected to need a new faucet, but Tyler’s thorough troubleshooting revealed that only the aerator needed replacing. He also identified the underlying cause: hard water deposits had clogged the small spray openings, creating backpressure that eventually blew out the aerator.
Knowing the tenants needed a working faucet as soon as possible, and that Moen uses proprietary parts, Tyler obtained a suitable replacement with my authorization and repaired the sprayer head. He also explained to the tenants how to use white vinegar to remove the hard water deposits and help prevent the problem from happening again.
That’s what I appreciate so much about Tyler: he’s incredibly thorough, takes the time to explain what’s going on (through a friendly call followed up by pictures of the issue and his completed work), and always looks for ways to save me money. The peace of mind that comes from having a plumber you trust, backed by a company that values prompt service and absolute honesty, is truly priceless.
I’m so grateful to have found Service Force Plumbing and they've earned a customer for life. Of note, my property manager has been so impressed with the work they have done for me over the past two years, that Service Force is now one of *their* go-to companies for plumbing issues! The owner, Roy, should be proud of having built a service that reminds me of the old days where customer satisfaction and honest services were valued.
