"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

To install or move washer and dryer hookups, you will likely need a combination of professionals. A plumber can handle the water supply lines and drain pipes. If you have a gas dryer, a plumber certified for gas lines or an HVAC specialist will be needed to run the gas line. An electrician is required to install the correct electrical outlets. For simpler jobs, a local handyperson may suffice, while a contractor might be needed for tasks like drywall repair for the new vents.

Plumbers can be held liable for their work for anywhere from a year to six years, depending on where you live, but in most states, premises liability lasts for three to four years. You can contact your state’s licensing board to find out how long your plumber is liable. Your local building department or a consumer protection agency in your area can also confirm the timeline for you.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

Copper pipes are the safest type of pipe for carrying drinking water because they won't leach chemicals into your drinking water. However, for the best water quality, you should use copper pipes with lead-free joint material. The next best options for carrying drinking water are CPVC and PEX pipes.

If you use copper pipes for drinking water, you should check your water’s pH level. If it has a pH value lower than seven, you'll need to balance your water acidity with a purifier to avoid corrosion that could affect your drinking water quality.
