In Niwot, a water heater needs replacing when the tank leaks, hot water runs short or rusty, or an aging unit keeps failing. Niwot is unincorporated, so building permits come from Boulder County's Building Safety and Inspection Services. Call the number on this page to be connected with a local plumber in Niwot.

When you call
The call goes to an independent plumber who serves Niwot. They'll want to know whether the heater is leaking, what fuel it uses, its size and location. During a visit they'll check the venting, gas or electrical supply, shutoffs and clearances. If water is on the floor, close the cold valve above the tank and turn off its fuel or breaker.
What affects the price
- Size, fuel and efficiency of the new heater
- Tankless or heat pump upgrades and the gas or electrical work they need
- Vent and connector updates
- Expansion tank, drain pan and relief line requirements
- Access in basements, garages or crawl spaces
- The county permit, inspection and haul-away
Niwot conditions
Niwot's water and sewer come from two separate special districts. Left Hand Water District supplies water from Lefthand Creek, Colorado-Big Thompson water and the Williamson Ditch, blended with purchased water from Boulder, Longmont and Central Weld County Water District, and disinfects with chlorine. Left Hand doesn't state its own hardness, though the Central Weld portion of its combined report shows soft water around 33 mg/L. Niwot Sanitation District collects and treats wastewater at its own plant and makes property owners responsible for the whole sewer service line from house to main.
Boulder County Community Planning & Permitting handles building permits for unincorporated areas, including Niwot, through Building Safety and Inspection Services at the Courthouse Annex, 2045 13th St. in Boulder, 303-441-3926. The county's page doesn't list water heaters specifically, so the plumber should confirm what's needed before the swap.
No gas utility is confirmed on an official page for Niwot here, so check your gas bill. If you smell gas, leave the house first, then call 911 and your gas utility from outside.
Niwot is a small community with a historic downtown, so housing ranges from older homes to newer subdivisions, and the amount of venting or connector work varies with the house.
Checklist
- Record the heater's gallons, fuel and age
- Clear the area around the heater and vent
- Find the main water shutoff
- Have your gas bill handy to confirm the utility
- Decide whether you'd like a tankless or heat pump quote too
