I debated between…read morewhich company to go with for too long before just calling them and getting on the books as my furnace was dripping a considerable amount of water heading into the winter. While it looks like they offer Request-a-Quote (score!) I ended up just calling them as I was out and about. They gave me a two hour window the very next day, then called before they showed up. The tech was the definition of efficient. Friendly enough, not much chit chat, just more or less there to look into things and get the job done. My only slight issue was just a few things that were lost in translation -- they had the address wrong, were not close on spelling my name right, and then the price. They told me they could fix the issue for $135 which I agreed to, then was a bit surprised when the bill was for $209 as the final bill included the parts & labor. No biggie and a very fair price for the tune up and replacement, just would've been nice to know the actual total. The total price did match up with my expectations, so no biggie, just worth noting as I feel like maybe they could automate their bookings/billing just a tad better. TL:DR; I appreciate how fast they were, how they diagnosed and fixed it, and the price point. I'd call them again if the need arises.

At the time, I didn't realize what a blessing that would be. Mark is incredibly experienced, knowledgeable, and friendly. He knew exactly what needed to be done in both situations and fixed the issues promptly. His communication was excellent. I never once had to chase him for updates. He consistently delivered clear, accurate information and kept me informed throughout the process. Mark responds to texts and calls in a timely manner, which is hard to find these days, and he completed the work within the promised timeframe. I cannot recommend Old School Plumbing enough if you're looking for reliable, high-quality plumbing services.

Latest: I needed a simple faucet replacement; something they've always covered. This time they had their plumber test for hard water and denied the claim when they found it. Pretty much every house in my area has hard water, so it's a built-in excuse to say no. This isn't the 1st time something like this happened with them, it was just my breaking point. It's clear the new strategy is to collect the monthly fee while finding ways to avoid actually providing service. Buyer beware.
