"Frank took care of the leaking pipe I knew about, and fixed another, much worse, leak I wasn’t aware of until he noticed the water meter was still running after fixing the first leak. He also replaced my garage disposal, fixed my running toilet, and even installed a new dryer vent hose! He gave me some very good advice for future upgrades to the plumbing system in my older mobile home. Frank was punctual, polite and friendly, and the fee was reasonable. I will certainly call him again for any future problems or upgrades."

"Trey called ahead and arrived at the time he said he would. He was personable, friendly, and professional. He cleaned and flushed my water heater, as I requested. He explained what he would do, and explained what he was doing as he did it. I was very pleased with his work. I would use Mainline Plumbing again without hesitation."
