"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."

"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!"

"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. "

Plumbing FAQs, answered by experts

Emergency plumbers charge a significantly higher rate than for standard service, typically 1.5 to 3 times the normal hourly cost. You can expect to pay between $100 and $500 per hour, with an average of around $200 per hour. In addition to the higher hourly rate, many plumbers charge a flat emergency service or trip fee, which can be between $150 and $300. The final cost depends on the timing of the call; prices are highest for major holidays, followed by weekends and after-hours service on weekdays. For a complex job on a major holiday, a master plumber's rate could reach as high as $600 per hour.

Usually it’s fine to leave a toilet clogged overnight, as long as it’s not close to overflowing. In some cases, the extra time may give the clog time to work itself out. For example, if it’s caused by an excess of toilet paper, letting it sit could result in the clog dissolving and you may be able to simply flush it away by the time you wake up. 

Only let it sit though if you have more than one toilet in the home.

There are several methods to temporarily or permanently fix a burst pipe. In a pinch, you can seal up a small leak with either silicon pipe tape or epoxy specifically designed for this purpose. You can also purchase a pipe repair kit that supplies a clamp and gasket to seal the pipe. In the long term, a plumber will either remove the damaged area of the pipe and add a replacement coupling or replace the entire length of the pipe between joints.

Pipes tend to burst once frozen for 24 to 72 hours. It takes temperatures 20 degrees Fahrenheit or colder for several days to freeze and burst pipes, rather than a day or two with temperatures hovering around freezing. When temperatures are dropping, it’s time to drip faucets and open cupboard doors that house pipes to circulate heated air.

There are several types of sink drain stoppers, including pull-out, twist-and-pull, and pop-up. Pull-out sink stoppers can be removed by pulling on the stopper until it comes out of the drain. A twist-and-pull design requires lifting then turning the stopper to lock it in an open position and the opposite action (turning, then pressing down) to close it. A pop-up sink stopper works by pushing down the drain cover to open or close the passageway.
