How to choose a plumber in Westminster, CO

- Free to call
- No forms to fill out
- You decide after hearing the estimate
Check the license
Colorado requires plumbers to hold a state license. The State Plumbing Board lists three license levels, residential, journeyman and master, and apprentices are registered rather than licensed. A plumbing contractor must employ a supervising master plumber.
The State Plumbing Board links a license lookup, and Colorado's Department of Regulatory Agencies advises consumers to check a professional's license before hiring them. Ask for the plumber's name and license number and look them up yourself.
Colorado's law lets owners do plumbing work on their own residence. That exemption does not cover rentals, property that is for sale or commercial buildings, so those jobs need a licensed plumber.
Ask about permits
Many plumbing jobs need a permit and an inspection. In Westminster, the city's Building Division says a permit is needed to install or replace a water heater, to modify plumbing, to install a whole-house water softener, or to repair or replace underground sewer or water lines. It says no permit is needed to replace a fixture in the same place, clear a stoppage, or repair a leak when no pipes or valves move.
Other cities have their own lists. Broomfield, for example, says all water heaters need a permit, new or replacement. Ask the plumber whether your job needs one, who will pull it, and when the inspection happens. A contractor must pull the permit for their own work.
Get the estimate in writing
A good estimate says what the plumber will do, which parts they will use, what is not included and how long they expect it to take. It also lists the permit and any trip, inspection or after-hours charge. This website does not set or publish prices, so those details come from the plumber.
If the job is large, such as a sewer line or a water heater replacement, consider a second estimate. Compare the same items on each, not just the total.
Read advertising claims with care
Ads and listings often promise "24/7" service, quick arrival or the lowest price. Treat those as questions to ask, not facts: ask what hours the plumber actually answers, what the call-out charge is, and whether the quote is firm.
Online ratings and reviews can show how a company treats customers, but they are no substitute for a license check. Read several, look at how the company answers complaints, and be cautious of a listing with only a few glowing comments or none at all.
Be careful with anyone who asks for the full payment up front, will not give a name or license number, or pressures you to decide on the spot.
Questions to ask on the phone
- What is your Colorado license number? Then look it up.
- Does this job need a permit? Who pulls it, and when is the inspection?
- Can I have the estimate in writing? Ask what is included and what is not.
- Are there trip or after-hours charges? Ask before they come.
- What happens if you find something else? Agree on how extra work is approved.
Know who owns which pipe
Cities in this area publish where their responsibility ends. Westminster says the owner is responsible for the sewer line from the property to the city main. Arvada says the homeowner maintains the line from the house to the main. Broomfield says the resident owns the water line from the meter into the home. Ask the plumber which side of the line a problem is on before you pay for a repair.

What do plumbers fix?
Plumbers work on the pipes, fixtures and equipment that bring water in and take waste out.
In a home, that covers leaks and burst pipes, clogged and slow drains, water heaters, sewer lines, toilets, faucets and fixtures, shut-off valves and low water pressure. In a business, it adds restrooms, floor drains, grease lines and larger water heaters. Each of these has its own guide on this website, starting with plumbing repair, drain cleaning and water heater repair.
Some things that look like plumbing are usually a different trade. Furnaces and air conditioners, electrical wiring and appliance repair are normally handled by other professionals, although a plumber may disconnect or reconnect the water supply. If you are not sure which trade you need, describe the symptom when you call.
When to call a plumber
The right moment depends on what is happening, not on how long it has been going on.
- Right away: water you cannot stop, sewage coming back up, a split pipe, a heavily leaking water heater, water near the electrical panel, or no water in freezing weather. Start with emergency plumbing.
- Within a day or two: a drain that keeps clogging, a toilet that will not stop running, a faucet that drips steadily, low pressure at several fixtures, or no hot water.
- Schedule it: a minor drip, an old shut-off valve you would like replaced, a toilet that rocks, or a water heater that is aging but working.
- Call and describe it if unsure: a damp spot, a smell or a jump in your water bill. A quick description is often enough to judge how urgent it is.
If you smell gas, leave the building and call the gas utility or 911 from outside. Do not wait for a plumber.
Choosing a plumber: common questions
What do plumbers fix?
Leaks and burst pipes, clogged drains, water heaters, sewer lines, toilets, faucets and fixtures, and the pipes and equipment in businesses. Heating, cooling, electrical and appliance repair are usually other trades.
When should I call a plumber?
Right away for water you cannot stop, sewage backing up, a split pipe or a heavily leaking water heater. Within a day or two for a repeat clog or no hot water. Schedule minor drips and aging valves.
How do I check a plumber's license in Colorado?
Colorado licenses plumbers through the State Plumbing Board, part of the Division of Professions and Occupations. The board's page links a license lookup, and the state's consumer advice is to check a license before you hire.
Who pulls the permit for plumbing work?
In Colorado both homeowners and plumbing contractors can pull permits, but a contractor must pull the permits for their own work and cannot use a homeowner's permit. Ask the plumber who will pull yours, and whether the job needs one.
Can I do plumbing work on my own house?
Colorado's law allows owners to do plumbing on their own residence, but not on a property that is for sale, resale or rent, or on commercial buildings. The permit and inspection rules still apply.
Is a written estimate really necessary?
It is the easiest way to compare plumbers and avoid surprises. Ask for the work, parts, permit, and any trip or after-hours charges in writing before you approve the job.
