"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."

"Rocco was extremely professional throughout my dealings with him. He prepared me well for the work that needed to be done and walked me patiently through the process. He listened to all of my questions on his initial visit and offered his suggestions without being pushy or trying to sell me anything. When I asked for references for an engineer to survey my property, he found me one in my area that was affordable and just as professional. Rocco told me the work itself would take two days, but on the first scheduled day he showed up with a big team and was able to complete it in just one day. And to top it off, he left me with great instructions on how to grow the grass back in the area where he installed the well. All in all, the experience was a great one and Rocco will be my first call for any future projects.

"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."

"They contacted me to address the work within a short period after purchasing the deal. We worked out a good time and they came as agreed. Just need to be mindful of what you purchased and stay cognizant when starting the work. The installer, Kevin, did a fabulous job addressing what needed to be done. The quality of the work was very good. Would definitely hire for other 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

Most faucets come with a rubber or plastic gasket that prevents leaks—but that’s not always the case. If your faucet doesn’t come with a gasket or it’s leaking, use a caulk gun to seal the gaps and prevent water damage.

While you can put Drano in a sink with standing water, most plumbers don’t recommend doing so. It usually doesn’t help to clear the clog, and you’ll end up with a sink full of standing water plus a toxic chemical—which is very unpleasant to deal with and best handled by a professional.

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

Depending on the issue and materials, costs range from $150 to $500.

Porcelain and enamel sinks have very similar appearances, but they aren’t the same. Porcelain is a ceramic made from natural clay, while enamel is a strong powder that’s glazed over a metal sink. Use a magnet to determine whether you have an enamel or porcelain sink. If a strong magnet sticks to the sink, it’s likely enamel. If it doesn’t, you probably have a porcelain sink. You can also use the model number on the sink (often found on the underside of the bowl) or information from the manufacturer to determine the material.
