"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

Most people choose PVC, or polyvinyl chloride/plastic, for their sewer line material. PVS has many advantages over other types of pipes. Mainly, PVC can resist corrosion and chemical damage, is lightweight (making it easier to install), is budget-friendly, and has an impressive life span (typically around 100 years).

A plumber or certified gas technician is responsible for capping gas lines. Gas lines require expertise and understanding of safety standards to ensure it’s properly sealed. Your local regulations may also have specific requirements for capping gas lines.

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. 

To file a claim against a plumber, you’ll need to contact their liability insurance company. You can ask your plumber for information about their insurer, or you can refer to the documentation you collected before you hired them. Let the company know you need to file a claim, and they’ll provide you with the next steps. Alternatively, you can ask your homeowner’s insurance company to help you file.

Switching to city water from well water requires running a private main service line from the closest main city line to your home. When comparing well water versus city water, city water is routinely tested and readily available but can be more expensive than well water.
