Our Services
Longmont’s water supply is among the softest in the Boulder County region, with the city drawing 62 percent of its supply from the Colorado-Big Thompson Project, delivered from the western slope via Carter Lake and the St. Vrain Supply Canal to the Nelson-Flanders Water Treatment Plant. That snowmelt-fed surface water produces notably low mineral content, which reduces scale accumulation but does not eliminate the corrosion and wear patterns that develop in pre-1940 Downtown homes and 1970s–1980s copper systems as those plumbing materials approach or pass their expected service lives.
Here are the plumbing and drain services available to homeowners in the area:

Fast repair when a January cold snap splits a line in a crawl space or exterior wall.

Where We Serve
Longmont’s residential geography runs from the tree-lined streets of Old Town, where bungalows and brick homes from the early 1900s carry plumbing systems of considerable age, through the 1970s and 1980s subdivisions that form the city’s established core, to newer communities like Prospect New Town and Somerset Meadows where modern construction and active development present their own service and installation needs. Precision Plumbing Heating, Cooling & Electric serves the whole city, including the following neighborhoods:
Here are the areas across the community where Precision provides residential plumbing services:

All contractors performing plumbing work within Longmont city limits must hold a valid City of Longmont contractor license number; permits are submitted through the city’s ACA online portal and combination permits are issued when three or more trades are involved in a single project. The city currently operates under the 2021 International Codes and is preparing to adopt the 2024 versions effective July 1, 2026; Precision’s licensed plumbers carry active city registration and manage permit submissions on every qualifying job.
Longmont’s water supply draws heavily from the Colorado-Big Thompson Project, which originates from snowmelt on the western slope and is delivered via Carter Lake and the St. Vrain Supply Canal to the city’s Nelson-Flanders Water Treatment Plant. That snowmelt-fed surface water naturally carries low mineral content, making Longmont’s supply among the softest in the Boulder County region, in contrast to alluvial-well cities elsewhere on the Front Range that experience very hard water. Portions of the city outside the municipal system are served by the Left Hand Water District, which may have different supply characteristics.
Soft water reduces the scale buildup that causes accelerated water heater and appliance failures in hard-water communities, but it does not prevent the corrosion, joint wear, and mechanical degradation that accumulate in plumbing systems over time. Homes in Old Town Longmont dating from the early 1900s and 1970s–1980s homes throughout the city’s established neighborhoods are at the stage where supply valves, drain connections, and tank water heaters benefit from professional inspection regardless of water hardness.
Longmont sits at approximately 4,979 feet at the northern edge of the Boulder County plain, exposing homes to sharp winter cold snaps from the Front Range that can freeze supply lines in uninsulated crawl spaces and exterior walls. The city also lies within the St. Vrain Creek drainage basin, and spring snowmelt from the mountains to the west increases seasonal sump pump demand for properties in lower-lying areas. Precision’s emergency plumbing service is available around the clock when either condition requires an immediate response.
Non-emergency appointments are typically available within one to two business days. Precision’s around-the-clock support availability means urgent plumbing situations, including active leaks, frozen pipes, and water heater failures, can be addressed without waiting for standard business hours to resume.
