Improve Performance & Reduce Problems With Professional Smoke Chamber Repairs

That area of your chimney system that connects the fireplace to the flue is a pretty important area — but it can really take a beating from the heat of the fire. And when it does, you may not be able to see the damage from where you sit, but it can negatively impact the safety and performance of your entire chimney system. Here’s how:

The whole purpose of the smoke chamber is to take all the smoke and acidic byproducts produced by the fire and quickly escort them up into the flue and out of the home. In order to do this, the smoke chamber must be smooth and free of anything that could create drag or slow the smoke and byproducts on their way out. When holes and cracks develop, or the surface of the smoke chamber becomes jagged and rough, smoke, byproducts, and even heat can transfer to nearby walls and framing, and dangerous gases like carbon monoxide can enter the air supply. So let’s recap what a damaged smoke chamber means:

  • Decrease in performance. Instead of quickly leaving the chimney, smoke may find its way into your home when you enjoy a fire in your fireplace.
  • Decrease in safety. Heat can transfer, hot ash and spark can come into contact with nearby walls and framing, and either situation can cause a fire. Additionally, carbon monoxide and other dangerous byproducts can enter the air supply of your home when the fireplace is in use.

If you’ve noticed smoke problems or you think you may have smoke chamber damage, the easiest way to get confirmation is to schedule a chimney and fireplace inspection. There’s no easy way to see the smoke chamber, but we have video scanning equipment that will allow us to closely inspect the entire area — if there’s damage, we’ll know.
