"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 !"

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

Bleach—even diluted bleach—is not always the safest option for cleaning your drains. With a high pH, bleach can be highly corrosive to many types of pipes, especially when used regularly. When mixed with household cleaners and organic waste, it can also create dangerous chemicals. Remember to use proper protective equipment and ventilation when dealing with bleach.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Your pipes will not freeze just because you’ve turned your water heater off. Rather, pipes freeze when temperatures outside drop below freezing and the pipes are not properly insulated. In fact, leaving your faucets trickling with warm water (from the water heater) is one of the best ways to prevent your pipes from freezing in the winter.

Your water heater itself may have problems in the cold, so it’s important to winterize it each year. In addition, keep an eye on it throughout the year for problems and address any issues accordingly. For instance, here’s what to do if your water heater is leaking from the top.

It’s a good idea to drain your pipes to prevent them from freezing if you’re expecting extremely cold temperatures or planning to be away from your home for an extended period of time during the winter. You may be able to avoid draining your pipes if you insulate outdoor pipes and keep your home heated to a minimum temperature of 55 degrees.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.
