Serving Longmont's Old Town and Beyond
From the brick storefronts of Old Town to the newer neighborhoods stretching south toward the St. Vrain Greenway, Longmont is a city where older character homes and modern builds sit side by side. Done has served Boulder County homeowners since 1999, and we’ve seen every era of plumbing and electrical that Longmont has to offer — from mid-century galvanized pipes to newer PEX systems that need a quick repair.
Our Longmont technicians are licensed across all four trades: plumbing, heating, cooling, and electrical. That means one call gets you expert help no matter what broke. We’re part of a broader Boulder County service network that includes nearby Louisville and Lafayette, so our response times stay quick.
We show up on time, walk you through what we found, and quote the repair before we start. That straightforward approach is how we’ve kept customers calling us back for over two decades.

Call NowAbout our work in Longmont
Local knowledge, local response
Done! Plumbing, Heating, Cooling & Electric has kept Longmont and Boulder County homes comfortable since 1999, with licensed plumbers, HVAC techs, and electricians on call across the North Metro. One call covers heating, cooling, plumbing, drains, electrical, and water quality — and our crews answer 24/7 when something fails after hours.
We work in neighborhoods like Old Town Longmont, Prospect, and Southmoor Park and know the area around the St. Vrain Greenway, Roosevelt Park, and the Longmont Museum. Local homes run to a historic Old Town core surrounded by newer neighborhoods, so we size repairs and replacements to what Longmont actually has.
Longmont sees hot, dry summers and cold, snowy winters that push heating and cooling systems hard, which is hard on furnaces, AC systems, and water heaters. We tune, repair, and replace them before a Colorado cold snap or a July heat wave turns a small problem into an emergency.
