"A two-day project to convert tub to walk-in shower went smoothly. Jake, Josh and Brian were thorough in their site preparation and detail-oriented in the installation. It was a beautiful job and we appreciated the personal approach of the company: we didn't feel like ours was just one of an assembly-line make-overs."

"The workmen performed their work efficiently, professionally and with the utmost skill.  While installing a sliding glass door, an area was found that need to be corrected.  In my opinion they performed above and beyond to make sure our new sliding glass door would work properly, and not leak.  We also had our porch re-screened along with a new porch door.  I love the look of the porch.  A new folding attic 
staircase was also installed, and my husband is very satisfied."

"Tony was wonderful. I contracted with him in to finish a bathroom. The prior contractor made many majoristakrs with the drainage. Tony had to fix several major plumbing mistakes. He was up front, clear on the issues and what had to be done to correct the problems. Wonderful work and I will be contracting with him in the future."

Plumbing FAQs, answered by experts

If you don’t want to remove the sink stopper, pour ½ cup of baking soda and 2 cups of boiling water down the drain. Start by pouring 1 cup of boiling water, then the baking soda, followed by the remaining cup of boiling water. Use caution as boiling water can damage PVC or other plastic piping. Using a scrub brush or slightly abrasive sponge, clean the top of the stopper, and run the faucet to ensure the drain is clear and the stopper is clean. 

The likely culprit is an air lock somewhere in your pipes. This is especially true if the warm water upstairs is accompanied by a decline in water flow. Other causes of this issue include frozen pipes, leaks, damaged supply lines, and more. There’s a simple DIY fix to try for air locks: Turn the hot water and cold water faucets on for a minute, then turn off the cold water and then the hot water. Repeat this process two or three times. 

You can use other ways to seal the space where your tub and the bathroom tile meet. Using sealant tape, epoxy sealer, and spray foam can be just as effective as caulking your bathtub. When using alternatives to caulk, the one that is best for you depends on your preferences. 

Sealant tape takes less time and effort to use, which is why some homeowners prefer it. Meanwhile, epoxy sealer creates a smooth and glossy finish that can complement your bathroom. Lastly, spray foam is waterproof and can act as insulation for your tub.

A shower diverter and a shower valve serve different functions, though some modern models combine them into a single unit. A shower diverter is a specific type of valve that directs the flow of water between different fixtures, such as from a tub spout to a showerhead or handheld sprayer. In contrast, a shower valve (often called a mixing valve) controls the water temperature and turns the shower on and off. A shower system can have both a diverter valve and a mixing valve to manage its functions.

In the warmer months, it’s fine to leave your garden hose attached to your spigot. However, before the first frost of the year, make sure to disconnect your hose from your outdoor faucet and drain any leftover water inside. Otherwise, water could freeze in the hose and potentially burst inside your faucet or pipes.
