Plumbing, Heating & Air Conditioning in Williston, Vermont

Provost Mechanical LLC was founded right here in Williston, Vermont — and we've been showing up for our customers and construction partners ever since. After more than 10 years working in the trade, owner Shaun Provost is decided to build something of his own — a mechanical contracting company that puts reliability first. No runaround. No no-shows. Just skilled, licensed tradespeople who take pride in their work and respect your schedule. We specialize in residential new construction and light commercial construction, which means we understand the pace and pressure of a build site. Builders and general contractors trust us because we coordinate seamlessly with other trades, hit our milestones, and communicate clearly from start to finish. Provost Mechanical is fully licensed and insured in the State of Vermont, so you can have confidence in every pipe we run and every system we install. We're not a big-box operation — we're your neighbors, and we treat every project like it's our own.
