Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Chimney Damper Repair in Fullerton
The systems we see in Fullerton tend to share a history — a heating system replaced once or twice, cooling added later, and ductwork extended as rooms were added rather than designed for the house as it now stands. Most comfort complaints here start there.
About 51% of homes in Fullerton predate 1970, so the original heating system has usually been replaced at least once and cooling added afterward; 68% of them heat with natural gas, so oversized flues left behind by an earlier fuel are the recurring finding here. (US Census ACS 2022)
Why throat dampers stop sealing
The damper most houses have is a metal plate at the throat of the firebox, sitting in the path of everything going up and everything coming down. Soot and grit build on the seat and the plate warps with heat over decades.
Even when it works it is metal on metal, designed to close rather than to seal. And in California an enormous number have been deliberately fixed part-open for a vented gas log set, which is correct for the appliance and permanent for the house.
What the gas conversion did
Vented gas log sets generally require the damper to be permanently fixed part-open so combustion products cannot spill into the room. That is a code requirement, not an installer shortcut — but the consequence is an opening in the building that stays there year- round.
Repair before replacement
A seized damper is often just fouled. Cleaning the seat and pivot and freeing the mechanism restores it.
Top-sealing dampers and gas appliances
A top-mount damper closes over the flue at the crown with a silicone gasket, sealing far better than any throat damper, and it doubles as a rain cap. On a wood-burning or unused fireplace it is usually the better answer.
Where a vented gas appliance is installed, whether any damper may close at all depends on the appliance and on code. That is a question to settle before fitting anything, not after.
What an open damper costs
Conditioned air leaving through the roof, for most of the year in a house running air conditioning through a California summer.
Unvented appliances are different again
Ventless gas appliances have their own requirements and their own restrictions by jurisdiction. Ask what you actually have before assuming.

Chimney Damper Repair in Fullerton — FAQs
Do you cover all of Fullerton?
Yes — all 8 ZIP codes in Fullerton and the surrounding towns. Tell us where you are and we put you in touch with a company that covers it.
How quickly can someone get to me in Fullerton?
For a routine inspection or sweep, usually within a few days, and sooner outside the fall rush. Late spring through early fall is the quiet season and the easiest time to book. If you have had a chimney fire, or you can smell gas or have a carbon monoxide alarm sounding, that is not a scheduling question — leave the building and call emergency services from outside.
My fireplace smokes into the room. What is wrong?
Several possible causes, and they need different work. A blocked cap or arrestor, a damper not opening fully, a smoke chamber that was never parged, a flue too small for the fireplace opening, or a chimney too short relative to the roof around it. A house sealed tight enough to run under negative pressure will also pull air down the flue. An inspection separates them; guessing does not.
Should the chimney be repaired or rebuilt?
It depends how far the damage goes. If a key scrapes mortar out but the brick is intact, that is repointing. Once brick faces have flaked through, a brick can be rocked by hand, or the stack leans, repointing has nothing sound to bond to and a rebuild is the honest answer. Most rebuilds stop at the roofline, because that is the section taking weather from every side.
Do you charge for a quote in Fullerton?
We charge nothing at any point — contractors pay us, you never do. What a company charges to attend or to carry out an inspection is theirs to set, so agree it with them before they come out. An inspection is a real piece of work with a written report attached, and it is reasonable for it to be chargeable.
How often should a chimney be inspected?
Annually, whatever it vents — that is the NFPA 211 standard and it covers gas and oil appliances as well as wood. Sweeping frequency is separate and depends on what and how much you burn. An appliance used twice a year still needs the annual look, and those are the ones where neglected faults turn up.
Ours is clamped open. Is that wrong?
Not necessarily — it is usually required for a vented gas log set. It does mean the opening is permanent, and a top-mount damper is not an option while that appliance is in place.
Is a top-mount worth it?
On a wood-burning or unused fireplace, yes. It seals properly, keeps the flue dry and replaces the cap.
