Damper Repair by Jack & Sons Chimney Care in Colorado

The damper is the valve that opens the flue for a fire and closes it to keep heated or cooled air from escaping. When it rusts, warps or won't seal, you're either stuck with a flue that won't open or a chimney that leaks your energy bill up the stack. We repair and adjust dampers so they work — and seal — the way they should.

Signs you need damper repair

  • The damper is stuck open or won't close fully
  • You feel a cold draft even with the damper 'closed'
  • The damper is rusted, warped or won't budge
  • You hear it rattling in the wind
  • Energy bills climb during heating and cooling season

The benefits

  • A damper that opens and closes smoothly
  • A proper seal that stops energy loss
  • Safe operation when you want a fire
  • Options like top-sealing dampers for a tighter close
  • Lower heating and cooling waste

Our process

Test the damper

Seal upgrade if wanted

A top-sealing damper can be added for a much tighter close.

Confirm operation

We verify it opens, closes and seals correctly.

Commercial & residential

We handle damper repair for both homeowners and commercial properties — single-family homes, apartments, HOAs and businesses across the Front Range. Whatever the setting, you get the same careful, code-compliant work and honest pricing.

Damper Repair FAQs

Why does my closed damper still let in a draft?
Throat dampers rarely seal tightly, especially once rusted. A top-sealing damper at the top of the flue closes much tighter.
Can a stuck damper be repaired or does it need replacing?
Often it can be freed and adjusted. If it's badly rusted or warped, replacement is the better long-term call.
