"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"Workmen were excellent. They asked for direction when appropriate, but otherwise worked independently as a well coordinated team. Finished shower and plumbing is great. No issues whatsoever."

Customers say: Super punctual

"We hired Jeff based on reviews from Angie's List. We wanted our basement converted to 2 bedrooms, bath, and workshop. Based on already roughed-in plumbing, he completed the job with help from a plumber and electrician. In order to comply with window egress codes, he built benches in both bedrooms beneath the windows, after replacing the windows with compliant models - by crawling under a 3-ft deck. He was punctual, reliable, and we trusted him in our home. He is quiet and straightforward, and he provided us with itemized invoices. He is about to begin a second bathroom renovation for us and we have hired him for a partial garage re-build. We recommend Jeff with no reservations - from framing to painting to carpentry."

Plumbing questions, answered by experts

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

When you put baking soda and vinegar down the drain, they chemically react and help break down clogs. It’s not going to work for every type of clog, however. For example, it’s not the best way to get rid of grease buildup. For grease, you should try boiling water and white vinegar instead.

Technically, you can put an elongated toilet seat on a round toilet, but it’s not a good idea. Elongated toilet seats are a few inches longer than round toilets, so they will hang over the front edge of your toilet, which isn’t appealing. Additionally, an unsupported toilet seat or portion of a toilet seat is more likely to crack and shift, which could result in injury to whoever uses the toilet. Always match your toilet seat style to your toilet, or replace the toilet entirely if you’re looking to switch styles.

You might be able to find your pipe leak by doing a visual inspection around your appliances and under your sink. Don’t forget to check your water heater too. If you find moisture or puddles of water, then you know you’re on the right track—you may need a repair or water heater replacement.

Knowing how to find a water leak can be tricky, but you can try the paper towel method. Lay paper towels on the floor and see where the moisture lands. You can also wrap toilet paper around pipes to locate a small leak.

If you notice water coming out of the bottom of your tank or the flush handle, you obviously have a leaking tank. Water on the side of the tank can indicate cracks. Other signs include the toilet running and flushing without anyone touching the handle, needing to jiggle the handle to make the water stop after flushing, or needing to hold the handle down to empty the water tank.
