"Outstanding. Their employee Jared fixed everything quickly and was able to fix a faucet that a previous plumber had not fixed correctly. And did it all in about 2.5 hrs. This included replacing a three piece faucet in one of our bathrooms. Four diff jobs. Great Job Jared. ??"

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"I highly recommend the company (Costello's Plumbing) as well as the employee who helped us (Miguel). My wife spoke with Mr. Costello this morning, and booked an appointment for Miguel (one of his workers) to come over and look at the situation / prepare an estimate. He did so (arriving iwihin the appointment window), gave us a good quote, and indicated the two parts that needed replacement (the garbage disposal unit and the cold water dual shut-off valve. He indicated that we could purchase those parts through the company, or if I had the parts onhand, he could just install them (saving money). Fortunately, The Home Depot nearby was open, and I was able to get the two pieces fairly quickly. Miguel then: * installed the garbage disposal (and took care of getting rid of the old one), * connected the replacement shut-off valve, * replaced the faucet itself, and made sure that none of it leaked. A job well done!"

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"The project was done cleanly and quickly the next day after my posting to replace two shower Cartridges. There was confusion over the estimate (all estimates need to identify company). This might be good Angi upgrade. I may have assumed talking to wrong company. MasterFlush met me halfway on the estimate. One control was broken and therefore complicated. The other was quick and textbook. I was satisfied with the job done, next day service, and price. "

"We had problems with our refrigerator water pressure, kitchen faucet with no hot water, and several old stuck valves. Interviewed several plumbers from Angie. Camilo assessed the problems and explained what he would do clearly giving a competitive quote. He and Luis got the job done perfectly as soon as our new faucet arrived. What a joy to have ice water dispensing quickly and hot water while doing dishes! Thanks, Camilo and Luis."

"Oak Plumbing did excellent work and is very expensive. The guy, Zachary, they sent was very nice at first. He was here approximately 3to 4 hours and our bill was 2,000.00. We felt that was a bit expensive. Zachary was nice but he never pumped water through the washing machine to check if his work fixed our leak or there were other problems. Turned out a pipe was broken under the house. Zachary wanted an additional $500.00 to fix the broken pipe he missed. His personality changed when I asked him to lower the price. It was a PVC drainage pipe that needed to be replaced and the joints glued. I had to get another plumber. Zachary turned nasty, turned around, and walked away mad. He should have looked at the whole job and tested the washer after he was done. Fixing the pipes involved."
