Customers say: Quality work

"On Saturday, at about 4:00 in the afternoon, the toilet and shower in my master bathroom had overflowed so bad that it had seeped into my bedroom. (This had occurred simply after I ran the washing machine and dishwasher at the same time.) Suffice it to say, this caused a panic in me. Thankfully, I was able to ascertain the problem with the help from a friend who used to be a plumber. This helped me to realize that, though inconvenient, the problem at least wasn't some kind of emergency. With that, I immediately began reaching out to any plumbers I could find. The quotes that I was receiving were simply far too high for the job, especially because I know how to snake a clean line myself. In fact, I would have done so myself, were it not for my desire to have a camera down the line. (I had a clog about a year ago, so I was interested in seeing if there were any larger issues.) Of all of the plumbers that I got into contact withâ including one of my friend's plumber friendsâ Precise Plumbing had the best rate. They were willing to do the job at a rate that I could afford. Not only this, Malik, who had come out to do the job, worked with excellence. He was punctual, communicative, and competent. Not only this, he was also very personable. After he finished the job, he showed me the root problem that he picked up in the cameraâ which was actually roots. He explained long term solutions, but was in no ways pushy about it. I immediately put Malik's work to the test by running both the dishwasher and the washing machine again, which had caused the overflow in the beginning. You'll never guess what happened... nothing at allâ the problem was solved. Anyways, I write this review to say that Precise Plumbing is the way to go. I will definitely be telling my friends about them, but I hope the HomeAdvisor community could likewise benefit from such a competent company."

"The free estimate was conducted by phone with Matt.  He answered all of our questions fully, confirming that we did not need to install a larger unit and that all usual pipe and/or valves that needed to be replaced would be included in the quoted price.
The installer, Bobby, showed up within the stated time period, which was only two hours after the initial contact. He got right to work and was efficient, neat, and skilled.  He removed the old unit, took out some unnecessary pipes that were left from an old solar heating unit, and quickly installed the new unit.  He then demonstrated the thermostat operation, which is very different from the previous unit's, tested the operation, and cleaned up the area.
The price was reasonable. The unit has a good warranty (and looks nice ).  The Angie's List discount was applied with no problems.
My husband is a former plumber so he kept an eye on the whole install, and was pleased with the entire experience.

"We had a large cast iron sewer line under our house that needed to be replaced. Several plumbers in the area would not even take the job. They had several glitches with scheduling, but once the crew showed up they did the work in one shot, even staying overtime to complete the job. The team was courteous, hard working and did a quality job. Site was left clean. I would use them again."

"Plumbing 1 builders was the perfect team to come and help us with our needs. We got a full hardware replacement for our shower. They were quick and on time when it came to the quote process. They offered us the most competitive price in our area, while also being the most professional with the overall process. They didn’t try to upsell us on anything or spook us about our current set up, which did happen with other plumbers who came to give us a quote. They were quick and professional with the work as well. Everything exceeded my expectations in terms of execution. On top of that, they caught a weird error that was done by the builders and went out of their way to find a solution. We will most definitely reach out to them for any plumbing needs going forward!"

"Fito plumbers came out the very day I called. The young man who did the work was very polite, worked neatly, and wore a mask the entire time. He serviced my hot water heater which hadn t been done in 5 years. Less than an hour later the job was complete."

Affordable Plumbers FAQs, answered by experts

Professionals ensure proper sealing and connections, preventing long-term water damage.

Under normal circumstances, you don’t need to turn interior water off if it’s cold outside. But if you plan to be away during cold weather for more than a day, turning off the water can help prevent freezing and burst pipes. If you lose heat, turning off the water can help to keep pipes from freezing as well. You should turn off exterior pipes for sprinklers or outdoor irrigation for the season once temperatures begin to fall in the late fall and early winter.

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

The standard size of a pipe for the main water line ranges between 3/4 inch to 1 inch in diameter, but ultimately, the size will depend on your household size and its square footage. Depending on the size of the property, the water line size can range upwards to 1.5” in diameter for a very large house nearing 10,000 sq. ft. Incorrect pipe sizing can lead to potential damages and leaks. To avoid incorrect sizing, consider getting help from a local plumbing professional who can help you choose the right size and material for your pipe.

A running toilet is not a plumbing emergency, but you will want to try some DIY fixes or call in a plumber to prevent wasting gallons of water. The three most common causes of a running toilet are a broken or dirty flapper, an incorrectly sized chain between the flush lever and flapper, or a float that is out of position.
