"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

"Went well. I thought that I might need a new trap or elbow since water was leaking. As it turned out, it was the sprayer that was leaking and not the elbow. The tech did not try to oversell me all new plumbing and I appreciate that."

"I've used All Star Rooter on three occasions and have been very pleased with the work provided. Always professional, punctual and careful, they are specialists. An important indicator of their skill is their position in the industry - three different plumbing companies have recommended All Star Rooter. They will calmly approach a stressful situation and do their best to reach a successful outcome. On this occasion they were able to clear an on-going clog efficiently."

"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"The team from Gallery of Kitchens & Baths gave our bathroom the upgrade it desperately needed. The Salvatori marble vanity and Pittori cabinetry make it feel brand new and incredibly stylish. The craftsmanship, communication, and professionalism throughout the process were outstanding. Kudos to them!"

Plumbing FAQs, answered by experts

The main causes for a leaky toilet flapper include wear and tear or a broken or incorrectly installed toilet flapper chain. If your toilet flapper is torn or deteriorated, it can’t provide a proper seal to keep water from running. Meanwhile, a chain that has come loose, was moved, or just wasn’t installed right can prevent your flapper from fully closing.

Shut off the water if it’s safe to do so, and call a plumber as soon as you can. The longer a leak goes on, the more potential there is for water damage or a burst pipe. Repairing a burst pipe costs $500 on average. Then, remove any remaining water and ventilate the area.

The powder coating that creates a matte black faucet is pretty durable and will resist scrapes and scratches, but because it’s a coating, there is a chance that it will get scratched over time. Covering up scratches with matte black touch-up paint may be possible, but you may also risk it not blending in with the original finish.

Both plumbing inspection cost and length can vary widely based on the specifics of a property. For a larger home, historic home, or rental complex, a full plumbing inspection can take a full day. Put aside at least eight hours from the start of the visit to ensure that you'll be available to answer any of the plumber's questions. However, a thorough inspection of the average one-story to two-story home lasts just two to three hours.

A burst pipe can cause serious water damage within 24 hours. Once a leak or flood starts, mold can develop, floors and walls can become saturated, electronics can be damaged, and structural issues can occur. This process may be accelerated  depending on the severity of the burst pipe. Call an emergency plumber immediately when a pipe bursts in your home.
