Your boiler quit and the house is getting cold, or a whole floor stays cold while the rest of the home heats fine. That's why you're on this page, and it's the problem we solve. This is the boiler-focused companion to our full plumbing service in Brighton, narrowed down to hydronic heat. Brighton is a real gas-heat town: older blocks near downtown and Bridge Street were built when hot-water and steam heat were standard, and a lot of those boilers are on their second or third decade. If you want the wider picture of how our flat-rate boiler service and diagnose-first process works across the metro, that page covers the method. This one is about getting your Brighton boiler diagnosed and back on line.
Common boiler repair & service issues we fix in Brighton
No heat, boiler not firing at all
The most common winter call. Before we roll a truck we'll have you check three safe things: the thermostat and its batteries, the boiler's red service switch and breaker, and the pressure gauge (a cold system should read around 12 to 15 psi). If none of that brings the heat back, the fault is inside the system: ignition, gas valve, low water, or a locked-out high limit. That's a same-day call for us.
One zone or floor stays cold while the rest heats
The boiler fires but a whole zone won't warm up. On Brighton's older multi-zone systems this is almost always a stuck circulator pump, a failed zone valve, or air locked in that loop. It is rarely the boiler itself. We isolate the dead zone, test the circulator and valve, and bleed the loop rather than condemning the whole unit.
Boiler short-cycles or bangs on the first cold snap
A system that ran fine in October loads up in the first sustained sub-20 degree stretch and the weak part drops. Short-cycling (firing on and off every couple of minutes) wastes gas and hammers the ignition and pump. Usually a waterlogged expansion tank, a bad aquastat, or an oversized boiler. We find which before quoting.
Pressure gauge reads near zero or the relief valve is dripping
A cold system that has fallen to near zero psi has lost water and will lock out. A relief valve that weeps is either doing its job against high pressure or failing on its own. Both point to the expansion tank, the fill valve, or the relief valve, and all three are diagnosable parts, not a reason to replace the boiler.
Rich burn, soot, or a boiler set to sea-level spec
Brighton sits right around 5,000 feet. A gas boiler set up to a national-average spec burns rich here, wastes fuel, sooties the heat exchanger, and pushes carbon monoxide higher than it should. We confirm the altitude orifice and BTU input are correct for your elevation, not just that the unit lights.
Repeat no-heat calls every winter on an aging unit
If the same 15-plus-year-old boiler leaves you cold every January, you're paying for repairs that no longer hold. That's the point where we run the replace-versus-repair math honestly and show you both numbers. We don't push replacement, but we won't hide it when it's the cheaper path over the next few years.
What to expect, start to finish
1. Phone triage
Call (720) 880-8064 and tell us what's happening: no heat, a cold zone, banging, a dripping relief valve. We walk you through the three safe checks (thermostat, service switch, pressure gauge) and can often narrow the fault before we arrive.
2. On-site diagnosis, not a guess
We test the actual system: circulator, expansion tank, zone valves, ignition control, system pressure, and combustion. On a Brighton boiler we also check that the altitude derate and orifice are right for the elevation. We find the real fault before we price anything.
3. Flat-rate written quote, both options where it matters
You get a written flat-rate number before we touch a part. If a targeted repair will hold, that's the quote. If the unit is at the end of its life, we quote repair and replacement side by side so you decide with real numbers. No money down.
4. Repair on the spot when we can
We carry common boiler parts on the truck: circulators, zone valves, thermocouples, and ignition components. Most single-fault repairs finish the same visit, which matters when the house is cold and it's January in Brighton.
5. Permit and inspection on replacements and gas work
A boiler replacement, and any new gas supply run, requires an Adams County permit and a pressure test on the gas piping. We pull the permit, run the pressure test, and coordinate the county inspection ourselves, all included in the flat-rate. The inspection schedule is the county's, so we don't promise same-day on permit-required work.
6. Test, walkthrough, and written warranty
We confirm every zone heats, the system holds pressure, combustion is clean, and the altitude setup is correct. We show you the service switch and the pressure gauge so you know what a healthy reading looks like, and you leave with a written warranty.
Why Boiler Work in Brighton Is Its Own Job
Most boiler pages online could be about any town. This one can't, because Brighton stacks three specific conditions against a hydronic system, and after working boilers across Adams County we treat each one as part of the diagnosis, not an afterthought.
First, the water. Brighton municipal supply runs 15 to 20 grains per gallon, well into the very hard range, and head east toward Lochbuie or out along Highway 85 and County Road 2 and you're on private wells off the South Platte alluvial aquifer with their own iron and mineral load. That hardness scales the inside of a hydronic system the same way it scales a water heater, and on a boiler it means the fill water and any indirect hot-water tank tied to the boiler take a beating. When we service a Brighton boiler we look at the water it's being fed, not just the burner.
Older gas-heat housing stock
Second, the housing stock. The blocks near downtown Brighton and Bridge Street were built when hot-water and steam heat were the standard, and a large share of those boilers are 15 to 25 years old. Age alone is not a verdict, a well-maintained boiler runs 15 to 20 years, but an aging multi-zone system is exactly where circulators and zone valves give out on the first hard cold snap. We test those parts before we ever talk about the boiler itself.
Altitude and clay soil
Third, elevation and ground. Brighton sits right around 5,000 feet, close enough to the derate threshold that we verify the altitude orifice and BTU input on every boiler we touch, because a rich-burning unit wastes gas and raises carbon monoxide. And Brighton's clay-dominant soils shift hard with Colorado's freeze-thaw cycles, which is a problem for the buried gas and water lines that feed the boiler as much as for the drains. We check the gas supply can carry the boiler's full BTU draw before we ever fire a new install, and any new gas run gets installed and pressure-tested to code first. Call (720) 880-8064 and we'll walk through your system.

What Brighton homeowners say
"No heat on a Sunday in January. They walked me through the thermostat and pressure gauge on the phone, came out same day, and it was a stuck circulator, not the whole boiler like another company had told me. Quote matched the invoice."

Brighton boiler repair & service questions
My boiler isn't firing and I have no heat in Brighton. What should I do first?
Start with three safe checks before you call anyone. Confirm the thermostat is set to heat and swap its batteries. Find the boiler's service switch, usually a red switch that looks like a light switch on or near the unit, and check it and the breaker. Then read the pressure gauge: a cold system should sit around 12 to 15 psi, and a reading near zero means the system lost water and locked out. If none of that restores heat, the fault is inside the system (ignition, gas valve, low water, or a stuck circulator) and it needs a tech. Don't keep resetting a boiler that locks out repeatedly. We run emergency boiler repair with parts on the truck. Call (720) 880-8064.
Do you do emergency boiler repair in Brighton?
Yes. No heat in a Colorado winter is a same-day call, and Brighton's older gas-heat homes near downtown are exactly where a circulator or zone valve tends to give out on the first hard freeze. We carry common boiler parts on the truck (circulators, zone valves, thermocouples, ignition components) so most single-fault repairs finish the same visit. You still get a flat-rate number in writing before the work starts. Call (720) 880-8064 and we'll triage it over the phone first.
Should I repair or replace my boiler, and what does a new boiler quote in Brighton include?
It depends on age and the specific fault. Under about 12 years old with a single failed component (circulator, zone valve, expansion tank, ignition board), repair almost always wins because those are parts, not the boiler. Replacement starts to make sense when the heat exchanger is leaking, the unit is 15-plus years old with a major part failed, or a repair would cost 40 percent or more of a new boiler. A new boiler quote in Brighton is a flat-rate written number covering the unit sized to your home's actual heat load, the altitude derate for your elevation, the Adams County permit, the gas pressure test on any new run, and haul-away of the old boiler. We hand you repair and replace numbers side by side and let you choose.
Can you install a combi boiler in a Brighton home?
Yes, when it fits the home. A combi boiler makes heat and domestic hot water on demand from one unit with no storage tank, which suits smaller Brighton homes with lower simultaneous hot-water demand. The tradeoff is that heavy simultaneous draws (two showers plus a dishwasher) can outrun a single combi, and at Brighton's roughly 5,000-foot elevation the derated BTU output eats into the margin a combi needs to serve heat and hot water at once. We calculate your actual demand and confirm the gas supply can carry the load before recommending a combi, the same way we won't put a tankless water heater on a gas line that can't feed it. If a system boiler with a separate tank fits your household better, we'll tell you.
Does a boiler installation need a permit in Brighton?
Yes. Adams County requires a permit for a boiler installation or replacement, and any new gas supply run also requires a pressure test the inspector verifies. We pull the permit, run the pressure test on the gas piping, and coordinate the county inspection ourselves as part of the flat-rate quote. The permit fee is passed through at the county's fixed rate and we don't mark it up. Because the inspection schedule belongs to the county, we don't promise same-day completion on permit-required boiler work, but we handle every step of getting it permitted and signed off.
Why does my boiler need altitude adjustment in Brighton?
Brighton sits right around 5,000 feet, and gas burns differently at elevation than at sea level. Manufacturers require BTU input to be derated as elevation climbs, and a boiler left at a national-average spec runs rich here: it wastes fuel, sooties the heat exchanger, and pushes carbon monoxide higher than it should. When we service or install a boiler in Brighton, we confirm the altitude orifice and input rating are correct for your elevation, not just that the unit fires. It's a safety and efficiency check most homeowners never know to ask about.
Do you service boilers on well water east of Brighton?
Yes. Properties toward Lochbuie and along Highway 85 and County Road 2 pull from private wells off the South Platte alluvial aquifer, and that water carries iron and mineral content that varies well to well. Fill water and any indirect hot-water tank tied to the boiler are affected by what's in that supply, so on rural Brighton boiler work we look at the water feeding the system, not just the burner. If your treatment needs a look too, our full Brighton plumbing service covers well filtration and softening alongside the boiler.
