We Parge & Repair Smoke Chambers With Highly-Insulating & Effective Chamber-Tech 2000

We all want to be able to enjoy our fireplaces and the warmth they bring, without worrying about smoke wafting down into the home or heat transferring to walls and sparking house fires. That’s what your smoke chamber is for! It’s an inverted funnel-shaped section of the chimney system that protects combustibles in walls from heat transfer and encourages smoke and byproducts of combustion to swiftly move up into the chimney.

When in great condition and shaped and constructed properly, the smoke chamber should have no problem doing its job — but when there is damage (like cracks and gaps) or the smoke chamber is poorly designed, dangers could present themselves.

How Can You Tell If Your Smoke Chamber Is Damaged & What Can You Do?

You may be wondering, with its location just above the damper, how can you even tell if your smoke chamber is damaged or poorly designed? And if it is, what can you do about it?

While it’s certainly not easy to tell what condition your smoke chamber is in just by craning your neck up into the fireplace, a professional chimney inspection can make it easy. Here at ChimneyTEK, we have the technology needed to capture video footage and photos of the smoke chamber’s interior, and can show you exactly what damage is present and why we’re concerned.

Once we’ve inspected the smoke chamber, if damage is present or the design is flawed, we can repair and restore it using Ahren’s Chamber-Tech 2000. This product is essentially a refractory mortar that’s highly insulating and restorative by nature. We apply the product to the smoke chamber surface, filling in any cracks, gaps, or other openings, and leaving a seamless, airtight surface. We can also use this restorative product to reshape the smoke chamber, if needed.

What does parging your smoke chamber smooth with Chamber-Tech 2000 do?

  • seals cracks, gaps, and holes that could otherwise allow heat transfer and decrease safety and performance
  • reshapes and insulates the smoke chamber to better move smoke and byproducts up into the chimney flue and prevent heat transfer and house fires
