what we do best

What We Can Do for Your Chimney

Chimney Repair

When parts of your chimney break or stop working right, we fix them. We repair cracks, replace broken pieces, fix leaks, and make sure smoke goes up and out like it should.

Chimney Inspection

We look inside your chimney with a camera to find cracks, damage, or anything dangerous you can’t see. You get a report telling you exactly what’s wrong and what needs fixing.
aa chimney sweep and cleaning

Chimney Sweep and Cleaning

We scrub out all the black stuff (creosote) and gunk that builds up inside your chimney so it doesn’t catch fire. We brush the whole flue, clean the firebox, and remove anything blocking the airflow.
aa chimney flue

Chimney Flue

The flue is the tube inside your chimney that carries smoke and bad gases out of your house. We fix cracked liners or install new ones so your family stays safe from carbon monoxide.
chimney testimonials-6

Chimney Masonry

Bricks and mortar crumble over time from rain and cold weather. We replace broken bricks, fill in the gaps, and seal everything so water stays out.

Chimney Cap

A cap is like a lid for your chimney that keeps rain, birds, and leaves from falling in. We install metal caps that let smoke out but keep everything else from getting in.
aa chimney crown

Chimney Crown

The crown is the concrete top around your chimney that stops water from leaking inside. We fix cracks or build a new one so rain rolls off instead of soaking in.

We had concerns about a possible crack in the flue after a heavy storm, so we contacted AA Chimney & Air Duct for an inspection. The technician arrived quickly and walked us through every step of the process with total patience. Thankfully the flue was intact, but they recommended a full sweep which made a huge difference in airflow and overall fireplace performance. It’s such a relief knowing everything is safe and ready for winter.

The Hidden Risks of a Damaged Chimney

A Broken Chimney Isn’t Just a Structural Issue - It’s a Serious Safety Hazard ⚠️

25,000+ Chimney Fires Happen Every Year in the U.S.

Chimney fires cause over $125 million in property damage annually — and most start from creosote buildup that could have been removed with routine sweeping. In many cases, homeowners only realize the risk when they’re already worried and start looking for a chimney sweep near me to deal with the problem quickly. Regular visits from certified chimney sweepers help prevent fires before they start.

Just 1/8” of Creosote Can Ignite at 451°F

That tiny amount is thinner than a nickel — yet hot enough to start a chimney fire that reaches 2,000°F and melts metal components in seconds. This kind of buildup isn’t always visible, which is why experienced chimney sweepers recommend routine sweeping even when the fireplace appears to be working normally.

Carbon Monoxide Kills 430+ Americans Every Year

A blocked or poorly vented chimney can push CO back into the home, causing headaches, nausea, and deadly CO poisoning without any visible warning. When draft issues or strange odors appear, many homeowners decide it’s time to schedule a chimney sweep near me so airflow and ventilation can be properly checked by trained chimney sweepers.

Water Damage From Chimneys Costs Homeowners Thousands

A small chimney leak can spread into walls, ceilings, and insulation. Repairing the resulting mold, stains, and rot often reaches $2,000–$10,000+ — all from unnoticed cracks. Routine inspections by qualified chimney sweepers help catch moisture problems early, before they turn into major repairs that homeowners didn’t see coming.

Frequently asked questions

How do I know if my chimney needs repair?
Common signs include water leaking into the fireplace, cracks in the chimney or flue, bricks or mortar falling apart, smoke backing into the house, or strong odors even when the fireplace isn’t in use. If something feels “off,” it usually is.
Yes. Cracks, broken liners, or structural damage can allow heat, smoke, or carbon monoxide to escape into your home. Water damage can also weaken the chimney over time and lead to more expensive repairs if ignored.
Most damage comes from weather exposure, moisture, freeze-thaw cycles, poor ventilation, or normal wear over time. Even small cracks can grow quickly if water gets inside.
It depends on the type of damage, but in many cases it’s not safe. Using a damaged chimney can increase fire risk and expose your home to smoke or carbon monoxide. An inspection is the best way to know for sure.
We repair common issues such as cracked flues, damaged chimney crowns, leaking chimneys, deteriorated mortar, draft problems, and other structural or safety-related issues.
Many repairs can be completed the same day. Larger or more complex repairs may take longer, but we’ll always explain the timeline before any work begins.
No. Most chimney repairs are done from the roof or exterior. If interior access is needed, we take steps to protect your home and keep everything clean.
Costs vary depending on the issue, but catching problems early is usually much more affordable than waiting. We provide clear recommendations with our full $69 safety inspection.
Yes. Many leaks come from hidden issues like the crown, flashing, or flue liner. Even if the chimney looks okay, water inside is a sign something needs attention.
Yes. We always start with a full inspection to identify the problem and explain your options. If repairs are needed, we’ll walk you through everything before moving forward.
