"Andrew was great on time and personable. He knew what he was doing and even showed me the issues. He fixed what he was able to and advised me on what I need to do next since the next issue was not the plumbing. When I was urgently looking for someone to come fix the leak I had, everyone else was unable to make it the day of. Andrew made it in an hour from speaking with him. I would recommend his services to anyone needing a plumber."

"Anthony and Andrew from 1 & Done Plumbing totally exceeded my expectations! They contacted me prior to their arrival to inform me exactly when they'd be at my house. They were on time, professional, knowledgeable, respectful, kind and, most importantly to ME: down to earth. I felt at ease immediately when talking with them and I was extremely comfortable asking questions, which they answered promptly and thoroughly. The job they did was impeccable. I had 2 leaky faucets and a broken outdoor spigot. I was ECSTATIC with the work they did! My new faucets are beautiful and work perfectly! I can also enjoy gardening again because my spigot finally works and is so convenient! They also replaced some damaged pieces of pipe, which they showed me, that were corroded from the horrendous hard water where I live. Anthony and Andrew from 1 & Done Plumbing will be who I contact for any plumbing needs/issues I have. They have gained a loyal customer."

"They cut out the old dry wall, removed any and all mold, then replaced the dry wall, placed a tub and shower unit, they had their plumber come in and adjust our piping and install our new shower head and tub faucet all within 6-7 hrs. The installers were very nice, respectful, polite young men-- I would 10/10 recommend this company!!"

"Great results from waterproofing. Turned my spring flooding anxiety to calm. As humidity rose in summer, I put in a small dehumidifier. Made basement noisy as it struggled to dry and produced a lot of heat. As temperatures rose to about 83 down there and the humidity rose to over 68%, I had same people put in a whole basement commercial-grade dehumidifier. The small unit dropped the humidity to around 50% in less than an hour. Incredible performance and have me peace of mind and peace and quiet downstairs. Temperature dropped gas as well. Weel worth the price to save my most expensive investment."

Plumbing questions, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

How long it takes for a pipe to freeze depends on the outdoor temperature, the level of preventative measures taken, and how long the outdoor temperature stays below freezing. With this in mind, expect most pipes to freeze within six to eight hours. Uninsulated exterior pipes can freeze in under six hours if the temperature is below 20 degrees. It takes at least 12 hours for unprotected pipes to freeze at 32 degrees.

You should check water pressure twice a year to ensure there aren’t any irregularities and that it isn’t too high. It’s also smart to check it any time you notice symptoms of high water pressure (like banging pipes, inconsistent water flow, and leaky fixtures). Similarly, if you live in an area that’s prone to water pressure fluctuations due to municipal supply changes, elevation, or seasonal temperature shifts, check it more frequently. You can buy an affordable water pressure gauge and check the water pressure yourself.

The best place for a kitchen sink drain is the middle of the sink. Most people prefer center drains because they allow for better water and waste drainage, and the center location limits splashing because water flows straight down the drain hole. If the sink drain is too close to the edge of the sink, water can collect and drain too slowly. It can also be easier to clean sinks when the drain is closer to the center since debris is easier to wash down and doesn’t collect along the sides as easily.

Today’s standard sink stopper size is 1.5 inches. However, you can still find different sizes if your house uses an older sink stopper. Other sizes you can find in most hardware stores include one inch, 1-1/4 inch, 1-3/8 inch, 1-5/8 inch, 1-7/8 inch, 2 inch, 2-1/4 inch, 2-3/8 inch, and 2.5 inch.
