Canada's Best Duct - Chimney


A chimney is a pipe that allows smoke from a fire to exit your home. If you have a wood-burning fireplace and/or wood, you should clean your chimney every two years. However, if you use any form of combustible gas, such as propane, natural gas, or electricity for heat and cooking (even if it’s co-generation), it’s highly advised that you clear the chimney at least once a year.

An Overview of Fireplace and Chimney Maintenance

This assignment is quite simple to complete. However, if there is a significant accumulation of creosote, you will need to hire a professional to clear it out. We’ll teach you how to determine whether your repair is fit for a do-it-yourself effort. If so, proceed with the steps below. If not, you should engage a qualified chimney cleaner.

Is Cleaning A Fireplace A Do-It-Yourself Project

Remove any creosote accumulation from the fireplace. Because smoke chambers and smoke shelves are frequently the source of chimney fires, they are the regions that require the greatest attention. Examine yours to check if there is enough space to set a brush and reach it. If not, this isn’t a project you should do on your own.

Next, try if you can get to the fireplace chimney crown. If your roof slope is severe or you are uncomfortable working on your roof, this project is not for you. If this is the case, it is best to engage a trained chimney cleaner. Wear a safety harness if you decide to do it yourself.

Chimney fires cause damage to homes

Creosote may not appear to be harmful, yet it will ignite at 451 degrees Fahrenheit. When creosote ignites, it expands like a foam sealant. The flame may reach temperatures of over 2,000 degrees Fahrenheit in less than a minute and damage the chimney.

An skilled chimney sweeper should evaluate the chimney at least once a year for symptoms of degradation and vent problems. Every 50 fires, a chimney packed with green or damp wood should be cleaned or inspected. When moisture pops up at the ends of the logs during burning, the wood becomes wet. This sort of wood is inefficient and emits a large amount of unburned particles. It emits creosote and soot. Dry hardwoods, such as oak and birch, burn at higher temperatures and provide a cleaner flame. You may get your fireplace chimney tested and cleaned every 70 burns if you use this sort of wood.

How to Tell if Your Fireplace Chimney Needs Cleaning

Run your fireplace poker down the inner liner of your chimney to see whether it needs to be cleaned. If there is more than 1/8 inch of accumulation on the chimney, contact a chimney sweep.

Every year, 40 to 50 chimney fires occur. Waiting too long to contact a chimney sweep might result in creosote and soot accumulation. On rare circumstances, cleaning this hardened deposit necessitates the use of specialized techniques or chemicals.

A professional chimney sweeper must inspect the chimney liner for soot, blockages, and cracks. An older chimney may have cracks in both liner portions as a result of mortar wear and strain.

When hiring a chimney sweeper, make sure he or she is insured, certified to complete the task, and can offer you with a pricing estimate.

Inspections should be performed

Put on goggles and a mask. Empty the ashes from the firebox. The grate will be removed next. Allow the pressure to equalize before releasing the damper. Allow the heat to rise from the home for a few more minutes by opening the damper.

Scratch the surface of the firebox with your flashlight and fireplace poker. If the soot has a matte black finish and the scratch is less than 1/8 of an inch deep, it is a do-it-yourself project. Creosote can be seen when the build-up is deep and has a glossy or tar-like appearance. Stop using your fireplace and hire a professional chimney cleaner.

The Do-It-Yourself Chimney Cleaning Method

  1. Gather the Necessary Cleaning Supplies
  2. Collect Unique Firebox Brushes
    A single cleaning brush should not be used for all flues. As a result, you must scale your rooftop to determine the size of the flue liner. In addition, special brushes are necessary for the firebox and smoke chamber sections.
  3. Keep the mess to a minimum by taking care to preserve your surfaces and furnishing
    • Spread a canvas tarp across the fireplace and let it to spread around the room.
    • Insert the shop vacuum hose after removing the polyester sheets.
    • Use duct tape to seal everything and clay chimney flue liners as planters.
  4. Open a window to the outside
    • Construct your vacuum hose in parts, then link it to your shop vacuum outside.
    • Brush the filter while you vacuum, and replace it when it becomes clogged.
    • Before you begin brushing, get sheeting, a tarp, and a shop vacuum to protect the interior of your home from soot.
    • Because most vacuum filters are insufficiently strong to capture all of the fine soot from a fireplace, part of it blows right out the exhaust port.
  5. Cleaning Procedure: Brush the Flue
    • Brush the chimney flue a number of times, then gently let it rest for a few of minutes.
    • Before proceeding to the following section, use a powerful spotlight to double-check your work.
    • Begin by starting the vacuum and cleaning the fireplace from top to bottom.
    • Work your way up to the smoke chamber until you no longer feel brush resistance. Since you’ve arrived, climb to the roof and begin working inside the firebox.
    • Remove a tiny bit of the polyester sheeting and use a long-handled brush to wipe the smoke chamber.
    • Clean up all soot from the shelf using a noodle brush.
    • Clean the sides of the firebox with the long-handled brush.
    • Finish by carefully vacuuming the firebox.
    • You may now take the poly sheeting and canvas tarp outdoors after you’ve folded them up.
    • Shake out the brushes and save them for the next time you clean the fireplace.


You should clean your chimney every two years if you have a wood-burning fireplace and/or wood. If you utilize flammable gas, such as propane, natural gas, or electricity, it is strongly recommended that you clear the chimney at least once a year. A chimney laden with green or moist wood should be cleaned or examined every 50 fires. Dry hardwoods, such as oak and birch, burn hotter and provide a cleaner flame. As a result of mortar wear and pressure, older chimneys may have cracks in both liner parts.

Brush the chimney flue, then vacuum the interior of your home gently to eliminate soot. For the firebox and smoke chamber portions, special brushes are required. For cleaning a fireplace, you’ll need duct tape, a canvas sheet, and a shop vacuum.
