"I had a leak under my sink with water pouring out. Also a leaky washer and warm but not hot water in two showers. I called Mark and he was incredibly responsive, set up a time at my convenience. He is a very young guy, but incredibly knowledgeable. You gotta love that Scottish brogue!! My kitchen sink is a great example of what to expect from him, it was simply a hose that needed tightening. He showed me the problem, including how to fix it myself in the future and fixed it in about 2 minutes. With the washer, he told me it was an issue for the manufacturer, which I appreciated. He was able to quickly turn my warm shower into a hot one. I appreciate his honesty and expertise, he was great. He is the one I will call if I need a plumber again."

"We hired and worked with Rocco on two simultaneous bathroom renovations on the second floor of our house. (We were responsible for purchasing most materials, and Rocco and his team then worked with them.) While we did not vary the footprint, we did have them lower a few walls and replace them with glass in order to "open up" two rather claustrophobic shower stalls. We also installed new lighting and ventilation, along with replacing all of the existing fixtures. Working with Rocco and his son, Rocco Jr, was a lovely experience from start to finish. Rocco, Rocco Jr, and all of their subcontractors are exceedingly polite and professional and highly skilled. The tile work and custom glass for the showers were precise; the plumbing and electrical functions very well. The whole thing took about 8 weeks from start to finish, and we are very pleased with the results. Love our new bathrooms, and would not hesitate to use Rocco & team again! [Note: pictures were taken before glass was in, but give you a good idea of the look/craftsmanship.]"

"Andrew Laschyk is the owner of Two Rivers Interiors, and we dealt with him personally on everything, which was always a pleasure.  Andrew is warm and funny, and is completely professional in his work.  The only knock I could possibly give him is that he is, at times, difficult to get on the phone.  
When it comes to the work, the quality is the best I've seen.  We took a small, old, humdrum utilitarian kitchen and turned it into a showpiece.  The craftsmanship everywhere is superb, and on the crown molding is breathtaking.
Andrew and his workers were polite, professional and tidy; they did excellent work, and cleaned the place up beautifully when they were done.
Andrew prepared a detailed estimate, and never deviated from it without our advance consent.
Andrew does some really amazing large expensive work for people with mansions in our area, ad we were a relatively small job, but that made absolutely no difference to the quality of the work,  We are very very happy with the work does by Two Rivers; I would gladly recommend them to a friend, or to anyone, and would gladly hire them (and expect to!) to work on our home in the future.

"After several weeks of trying to find an honest, responsive, and fair company, we found our way to B-beka Plumbing and so glad we did. Bess came out and evaluated our needs and recommended a practical solution for us, taking into account our needs rather than a sales pitch for more complex and expensive options."

"Mr. Barlow and his team were very punctual and located the leak. They completed the work within 2 days and were available in a short period time. They were also very reasonable in price and very clean. When they finished their work, they threw out all old garbage and disposed of all unwanted materials as many workers don't do that nowadays. I was very happy with their service and work."

"Pacific Stone did a nice job. Person in charge of scheduling measurements and installation was pleasant and courteous. Within a few days of my inquiry they came out to my house to take measurements and they brought samples to choose from. Installation was done within a few weeks after that. Took away the old countertops and sinks. They know what they're doing. One of the installers was actually the owner and they were prompt and professional and cleaned up well."

Sink Installation FAQs, answered by experts

Depending on the issue, you have a good shot at fixing a leaking sink yourself. If you have some plumbing experience or are comfortable with DIY jobs, you can clean the P trap, tighten nuts, replace washers, and replace shut-off valve stems on your own. For more complicated jobs, such as repairing a garbage disposal, calling a pro may be the way to go.

According to the U.S. Environmental Protection Agency (EPA), a leaky faucet that’s dripping at a rate of one drip per second can waste more than 3,000 gallons of water per year. This is one reason why it’s important to fix a leaky faucet sooner rather than later.

Quartz sinks are incredibly durable, making them resistant to cracks and chips. They’re a high-density engineered stone, so they’re less likely to crack when exposed to daily impact. But because quartz sinks are so dense, they are very heavy, making installation a challenge. If you’re a novice, there’s a chance dropping one during installation could crack or break the sink. Additionally, repeatedly dropping heavy objects into them could create a crack.

Refinishing a bathtub is a project you can do at the same time as refinishing a porcelain sink. If your tub is the same age as your sink, consider getting a quote. Most homeowners spend about $480 on the cost of refinishing a bathtub, but it ranges between $335 and $630, depending on the size, style, and material of the tub.

Replacing the countertop with another that fits the same size and cut out shouldn't take longer than four to five hours. The installation job entails removing the plumbing connections, unscrewing the old sink connectors, removing the countertop, placing and gluing the new countertop, and connecting the plumbing hookups.
