Chimney cleaning is necessary to remove soot, blockages, and creosote buildup from your chimney.
If you don’t clean the chimney regularly and appropriately, the creosote buildup inside the area reduces the fireplace’s efficiency. The process of eliminating combustion gases is impeded and. Also, creosote buildup creates a substantial fire risk.
However, the chimney cleaning process isn’t as easy as it may sound. It’s not all about pushing a brush inside the chimney and “scrubbing” up and down.
To catch the creosote and remove any potential debris trapped in the flue, you need special tools. That’s where the chimney cleaning kit comes in handy.
Below, we discuss all the important points on chimney cleaning and answer pertinent questions homeowners often ask. First, though, a review of some of the best chimney cleaning kits.
Why Should You Clean Your Chimney?
With the winter season on the horizon, your HVAC technician has likely called to remind you about the need to clean your chimney. Even if the chimney itself looks perfectly clean, the technician may still insist on cleaning.
Some people choose to DIY clean their chimneys. However, your technician may also advise professional cleaning. The following is everything you need to know about chimney cleaning.
For one, you want to clean the chimney just because keeping a clean home means the chimney needs to be neat too. More importantly, though, you need to clean your chimney for the following reasons;
Prevent Chimney Fires
Chimney fires aren’t always big flames rising above the roof. No. Some studies show that many homes have had smaller chimney fires without the occupants even realizing it. These smaller fires are just as dangerous as the bigger ones.
The primary cause of chimney fires is creosote – a highly acidic residue that develops when hot combustion materials condense as it comes into contact with cold air in the chimney. The condensations ticks to the chimney wall, creating a brown to black residue known as creosote.
Initially, creosote is smooth and tar-like. However, it often hardens over time. Hard creosote is the worth possible thing you can have in the chimney. Aside from blocking the chimney, it’s highly combustible. The best way to prevent creosote buildup and avoid unnecessary fires is through regular chimney cleaning.
Remove Debris, Buildup, and Blockages
We’ve already mentioned creosote buildup. That’s rarely the only thing that may end up in your chimney. First off, debris, birds, and other animals will always find a way into the chimney, especially if there’s a significant opening at the top.
Raccoons are another typical visitor, especially when the chimney cap is missing or bent. These elements can block the chimney and create an additional fire risk.
Secondly, you’re probably aware that the fireplace, furnace, or stove produces multiple combustion byproducts, including smoke, carbon dioxide, soot, tar fog, hydrocarbons, acidic water vapor, and nitrogen dioxide. The chimney is designed to help these byproducts out of the home.
Twigs, branches, and leaves inside the chimney can block these elements from leaving the house, possibly causing buildup that may some of the gases to leak back into the home. The same applies to birds and raccoons in the chimney. It creates blockage, buildup, and ultimately a fire risk.
Prevent Foul Smells
One of the signs of a dirty chimney is unexplained foul odors. If you trace the foul smells to your fireplace, it’s likely the chimney. Often it’s the buildup of combustion byproducts, mostly soot, and creosote. However, it could also be a dead raccoon.
These foul smells are familiar during the summer season when the chimney isn’t in use. A bird may get trapped inside the chimney and rot there for weeks.
Cleaning the chimney at the end of the heating season can help prevent the smells. Another cleaning right before the next heating season is advisable as you don’t want to burn the trapped animals or other items that may create new smells.
Catch Potential Issues Early
Chimney wear and tear is standard. The flue lining may get damaged. If it’s a metal lining, it may develop bends or even tears, impeding the smooth exit of combustion byproducts out of the house. Clay and cast-in-place chimney liners, meanwhile, can develop cracks. Clay liners, in particular, are prone to breaking.
The chimney itself can get damaged too. For masonry models, the walls can crack, and the mortar can become loose. All these issues reduce the chimney’s efficiency and, in some cases, increase the risk of a chimney fire.
During the cleaning, the chimney sweep will note any potential issues and inform you about them so you can take steps to rectify the situation before the heating season begins.
How Can I Tell If My Chimney Needs Cleaning?
First off, it’s recommendable to schedule professional chimney cleaning at least once a year, ideally in the spring. This should be done even if the chimney appears to be in perfect condition.
However, you can also have the chimney cleaned more frequently, especially if you live in a colder region where heating is needed more often than not or in a woody area where debris is likely to fall into the chimney often.
For these latter two situations, you should look out for the following signs before calling the chimney sweep;
- Foul smells: We’ve already discussed the foul odors from the chimney. They may be a result of something rotting in the chimney. Or, it could just be creosote buildup. Whichever the reason, if you determine that the smell is coming from the chimney, it may be time to call the sweep.
- Visible tar deposits: Thick black deposits around the chimney area is another telltale sign that your chimney needs cleaning. Some of this deposit is sometimes found around the stove or on the damper. If deposits are everywhere and easily visible, it tells that the deposits inside the chimney could be substantial.
- Soot dripping into the fireplace: If there’s something blocking soot from leaving the chimney, it binds to surfaces within the chimney, including the chimney walls and flue lining. After some time, the buildup becomes heavy and can no longer resist the pull of gravity. So, you’ll see the soot particles falling onto the fireplace. Strong winds can also dislodge soot buildup.
- Smoke fills the room during heating: It’s never a good idea to wait until you see smoke filling your rooms to clean your chimney. It’s the clearest indication yet that there’s a blockage inside the chimney. Remember that smoke can damage your walls and furniture and even impact your health. Immediate sweeping is vital.
- Poor quality fire: You also know it’s time to clean up when you notice that your fire’s quality is poor. Fires need fresh air to burn healthily. But, when the chimney is blocked, the supply of oxygen is impeded. Moreover, combustion gases that can’t leave the house will be hanging around the fire, further denying it fresh air.
- Signs of animals: Finally, animals, including birds and rodents, love to nest in chimneys that aren’t currently under active use. Signs that there could be animals in your chimney include droppings, debris or brickwork becoming dislodged, chimney flue blockage. Chimney sweeping easily removes any animals.
How to Clean the Chimney
Ideally, you should call a chimney sweep to clean your chimney. It gives you a better chance of removing all the unwanted debris, creosote, and other elements. Better still, chimney sweeps, thanks to their experience, are more likely to catch potential issues that may need repairs.
However, if you decide to clean it on your own, the following is a step-by-step guide to follow;
Tools and Materials
- Chimney brush/cleaning kit
- HEPA vacuum
- Protective gear
- Drop cloths
- A spot-light
The vacuum cleaner helps with dust control as you clean and collect the soot and debris removed from the chimney flue. Drop cloths, meanwhile, help with covering and protecting the floors and furnishings.
The Step-By-Step Process
- Prepare the surrounding area: Remove all items in front of the fireplace and move back any furniture. Use old sheets to cover furniture and other dust sensitive items in the room to protect them from the soot and creosote.
- Lay tarpaulin: If there are any rugs near the area, roll them back. Then, lay down a tarpaulin or drop cloths in front of the fireplace. You don’t want every last drop of the creosote and soot entering the fireplace. Also, lay a dust sheet on the fireplace surround to collect soot.
- Remove the grate: Remember to wear your protective gear (eyewear, gloves, dust mask, etc.) first. Then, remove the grate from the fireplace as the final preparation before the cleaning process begins.
- Clean the fireplace: Taking care not to breathe in soot or creosote, use a soft brush and dry cloth to shovel out all the ash and debris from the fireplace.
- Inspect the chimney: Use the spot-light to check up the flue. If there’s a damper, make sure it’s open. Check for animals, birds, missing firebrick, and the presence of creosote. If the creosote looks hard and thick, you may need to call in a professional.
- Select the right brush: The brush you choose for the cleaning process will depend on your flue’s shape and size. Also, determine the height of the chimney and select the right-size rode. Then attach the brush to the rod.
- Start scrubbing: Push the brush up the chimney using a slight anti-clockwise movement. Then, once the brush is up there, scrub vigorously, adding more rods as you move up the flue.
- Remove the soot: Withdraw the brush. Then, lift the bottom of the dust sheet, remove the brush from the pile of soot, and shovel the sheet into a metal bucket.
- Vacuum and finish up: You’re almost there. As the final step, vacuum the area, reassemble the grate and surrounds, and shake out the drip cloths outside. You can safely bury the soot and creosote as both are environmentally friendly.
Chimney Cleaning FAQ
What Happens if You Don’t Clean Your Chimney?
Failure to clean the chimney can result in several issues. For one, leaves, debris, and nesting animals may block the flue, creating a massive fire risk. Additionally, blockages may cause combustion gases to leak back into your living rooms. An unclean chimney also guarantees poor flame quality and may impact heating efficiency and costs.
How Often Should You Clean Your Chimney?
The recommended frequency is once a year, preferably in the spring. Summer isn’t ideal as chimney sweep prices tend to rise due to increased demand. However, you can also clean your chimney more often, say twice or thrice a year, depending on where you live and how you use the fireplace/stove/furnace.
How Much Does it Cost to Clean the Chimney?
It depends on whether you’re doing it on your own or hiring a professional. If you’re DIY-cleaning it, then you only need to purchase the cleaning kit. Chimney cleaning kits are priced between $150 and $75. If you are hiring a professional, the charges will depend on where you live but typically range from $125 to $300, including inspection and sweeping costs.
