The first things a competent visit gets right
Boiler requests from Denver are routed to independent licensed professionals who already cover Denver County and reach Wheat Ridge on the same run. Where boiler is permitted work, the permit is pulled with Denver Community Planning & Development by the licensed contractor, not by the homeowner. Roughly 69 ZIP codes fall inside the Denver routing boundary, and a metro that size usually has several contractors bidding on this work.
- 1
Pressure, temperature and the expansion tank are checked
- 2
The system is bled and circulator operation verified
- 3
The system is balanced and cycled under load

Before you sign
What to ask a Denver contractor first
- 01
Which trade licence covers hydronic heating locally, since boiler work sometimes sits with mechanical contractors rather than plumbers?
- 02
Which fault was measured — control, circulator, expansion tank or heat exchanger — because only some justify repair on an ageing boiler?
- 03
Are replacement parts still available for this make and model, since obsolete controls often force a full boiler replacement?
Before anyone touches a pipe
Verify the licence. It takes two minutes.
- Who licenses the work: State Plumbing Board, Colorado Division of Professions and Occupations (DORA) together with the local jurisdiction.
- Who pulls the permit: Denver Community Planning & Development — the licensed contractor, never the homeowner.
- What to ask for: the licence number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Boiler in Denver — common questions
Why do my radiators knock?
Knocking usually means trapped air, water hammer from a stuck valve, or in steam systems a pitch problem letting condensate collect. Bleeding is the first step; persistent knocking is a diagnostic visit.
What boiler pressure is normal?
Most residential hydronic systems sit in a low static band when cold and rise modestly when hot — check the manufacturer's plate for your unit. Pressure that keeps climbing usually points to a failed expansion tank or a leaking fill valve.
Is a boiler covered by a plumber or an HVAC contractor?
It varies by state and by the credential involved. Hydronic and steam boilers are commonly plumbing-licensed work; forced-air is HVAC. Confirm the contractor holds the right credential for boiler work in your state.
Do I need a permit for plumbing work in Denver?
Permits in Denver are issued by Denver Community Planning & Development. As a rule, water heater replacement, gas work, sewer laterals and repiping are permitted work, while a like-for-like faucet or disposal swap usually is not. A licensed contractor pulls the permit — if one offers to skip it, that is the signal to stop.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberColorado cover?
All of Colorado: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
Is PlumberColorado a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberColorado routes the request and links every page to the official Colorado licence register.
Does PlumberColorado charge homeowners anything?
No. PlumberColorado may be compensated by a partner when a homeowner connects with a professional through the site. That never changes what the contractor charges for the job.
