Start with the symptom

Plumbing problems Boulder homeowners call about first

Each card opens the page that covers that problem in detail, from what to check before the call to what the plumber should document.

Water running over a white pipe fitting beside a brass pressure gauge

Leak detection

A stained ceiling, a meter that keeps moving with every tap closed, a wall that feels damp. Locating the source comes before any drywall is opened.

Drain cleaning

Slow tubs, gurgling toilets and a kitchen line that backs up again a week after plunging.

Repiping

Pinhole leaks that keep returning in the same run of pipe, and the choice between patching and replacing it.

Water damage removal

Water extraction and drying after a burst pipe or an overflow. The scope stops at removal and drying.

Some calls need a narrower specialist. Fuel gas work goes to the gas line repair page, a heater that is past saving to water heater replacement, and efficiency questions to the tankless water heater page. A wet slab floor points to leak under the slab, a dripping fixture to faucet and toilet repair, and a jammed sink to garbage disposal service. Offices, restaurants and apartment buildings have their own page for business plumbing calls, and mineral questions go to water softeners and filtration. Water supply pipes between the street and the house are covered under water line repair.

Burst pipe, backup or flood

Emergency plumber in Boulder: the first ten minutes

What you do before help arrives often decides how much of the house gets wet. These steps are safe for most homeowners and take no tools.

Find the main shutoff valve, usually near the water meter in a basement or crawl space, and turn it clockwise until the flow stops.
If the leak is at a single fixture, close the small valve under that sink or behind that toilet instead, and keep the rest of the house running.
Move rugs, electronics and boxes out of the wet area, and photograph the damage before cleanup so the record exists.
Call the dispatch line and say where the water is, whether it has stopped, and the street address. The dispatcher confirms availability for that address.

Gas smell? Leave the house first, then call 911 or the gas utility from outside. Plumbing dispatch comes after the area is safe.

Damp basement floor with scattered debris below a brick wall — Water that reaches a basement floor spreads quickly, so the shutoff comes before any cleanup.

Finger pointing to a brass valve on a copper pipe near a concrete wall — Find the main shutoff now, while nothing is wrong, and make sure it still turns.

Water still moving? Call before you mop

A running leak gets worse by the minute, and the dispatcher can talk you through the shutoff while a plumber serving your area is lined up.

Local ground rules

Four Boulder County facts that change the repair

Each fact comes from a city, county or state source, and each one changes what you should ask a plumber.

City water measures soft, so scale needs another explanation

The City of Boulder reports average hardness of 42 mg/L, equal to 2.4 grains per gallon, and its own monitoring scale rates anything under 60 mg/L as soft. If a city of Boulder heater or faucet is crusting over, ask the plumber to look at the heater age, its temperature setting and any softener before blaming the supply. Other towns on this list buy water from their own utilities, so check that utility's report for your address.

Sources: City of Boulder drinking water quality and City of Boulder/USGS hardness scale

The sewer service line is yours up to the city main

Boulder states that the sanitary sewer service line belongs to the property owner up to and including the connection to the city-owned main. When the lowest drain backs up, a camera inspection shows which side of that connection holds the blockage, which settles who fixes it before any digging starts.

A water heater swap needs a licensed plumber and a permit

A December 2025 memo from the Colorado Division of Professions and Occupations says water heater installation and replacement requires a licensed plumber, a permit and an inspection. Before you approve a replacement, ask who pulls the permit and when the inspection happens. Inside the City of Boulder, plumbing work that adds, removes or replaces fixtures also comes with a fixture count form.

Foothill cold snaps are a real planning item

Boulder's own winter guidance explains that water expands as it freezes and can split a pipe. In Nederland, the town utilities department has warned residents about temperatures near -20°F and told them to locate the shutoff, insulate pipes and protect the meter. Before the first hard freeze, find your shutoff, wrap pipes in crawl spaces and exterior walls, and disconnect garden hoses.

Quick triage

What the symptom usually points to

A first safe check for each, and the page that goes deeper.

Common symptoms, likely sources and the first safe check
What you notice	Likely source	First safe check	Where to read more
Meter dial turns with every fixture closed	A leak on a supply line or inside a fixture	Shut every tap and appliance, then watch the dial for a minute	Leak detection
Several drains gurgle or the lowest one backs up	A partial blockage in the main drain	Note which drain fails first and whether it follows laundry or showers	Sewer line repair
Hot water runs out fast or turns lukewarm	A failed element, thermostat or gas control, or a tired tank	Read the heater label for its age and check the breaker or pilot as the manual describes	Water heater repair
Pinhole leaks keep showing up in different spots	Pipe wall wearing out along a whole run	Mark each leak location and date so a plumber can see the pattern	Repiping
No water at any tap, or a frozen pipe after a cold night	A closed main valve, a frozen run or a supply problem	Check that the main valve is open, then look for frost on exposed pipe and keep taps cracked	Pipe repair
Pressure drops at every tap and the yard is soft	A leak on the water line from the street	Check the meter with the house shut off and look for wet ground near it	Water line repair

Not sure it counts as an emergency?

If water is moving, a drain is backing into the house or a heater is leaking, treat it as one. Call, describe what you see and the dispatcher will sort out the rest.

Before the visit

What happens when you call

The dispatcher asks for the street address, what the plumbing is doing and whether the water is shut off. That is enough to match the job to a licensed and insured plumber who covers your area.

Night, weekend and holiday calls reach the same dispatch line, and same-day service is offered when availability allows, and the dispatcher says so on the call, not in advance. If your address sits on the edge of the service area, the dispatcher confirms coverage before anyone is sent.

Have the street address ready
Say whether the water is off
Mention any gas smell first
Keep the photos you took

Coverage

Where the dispatch network serves the Boulder area

The network reaches Boulder and the cities and towns around it, from Golden and Arvada in the south to Longmont and Lyons in the north, and up the canyons to Nederland, Jamestown and Ward. Pick your town to see local details.

Building permits come from different offices depending on the address: the City of Boulder, one of the other city or town building divisions, or Boulder County for unincorporated land. The county also reviews plans and inspects work in Jamestown, so a permit for a Jamestown plumbing job runs through the county. Source: Boulder County building permits
