OVERVIEW
A Safer Chimney Built on the Outside of Your Home
An exterior chimney runs up the outside wall of your house, which makes it a smart choice when there is no clear path to route a chimney through the inside. Whether you are adding a fireplace, a wood stove, or a new heater, the right exterior chimney gives your home strong draft, steady heat, and clean, safe venting for years to come. It also keeps combustion gases out of your living space, protects the structure of your home from heat and moisture, and adds lasting value to the property.
Our team handles the full exterior chimney installation from the first free estimate to the final safety check. We size the system to your home, anchor it securely to the wall, seal every connection against wind and rain, and finish clean. The result is a durable exterior chimney and a home that looks and feels the way it should. A new chimney installation is a long term investment, so we take the time to do it once and do it right.

WHEN YOU NEED IT
Signs You Need an Exterior Chimney Installation
Homeowners come to us for an exterior chimney installation for a handful of clear reasons. If any of these sound like your home, we can help you plan the right new chimney installation.
-
Adding a fireplace, stove, or heater
A new heat source needs a safe way to vent, and an exterior chimney gives it a proper path to the outside without tearing up your interior.
-
No interior path available
When walls, floors, or framing leave no room to run a chimney through the inside of the house, building it on the outside wall is the cleaner solution.
-
Relocating a chimney during a renovation
If you are reworking a room or opening up a floor plan, moving the chimney to an exterior wall keeps your project on track.
-
Replacing a failed exterior chimney
When an old chimney has rusted, cracked, or started to lean, a full replacement protects your home from collapse and keeps venting safe.
-
Fixing draft or clearance
If your fireplace smokes, drafts poorly, or sits too close to the roofline, a correctly built exterior chimney restores proper draft and safe clearances.
-
Persistent odors or moisture
Musty smells, water stains near the fireplace, or a chimney that never seems to dry out are signs the current venting is failing.

What Our Clients Say
Mike S.
Chimney Professionals did a terrific job cleaning my two wood burning fireplaces in a Manhattan brownstone. They came within one day. Their equipment is state of the art, and it was all done in less than 30 minutes. Everything kept spotless. The price was right too.

Not only did they answer right away, they had Rod at my door first thing Monday morning and sourced a hard to find part same day when others could not. They beat every other quote I got and had our system back up and running in under an hour.

Bruce S.
The chimney in my 115 year old brick rowhouse had a badly deteriorated terra cotta lining. Michael gave me a fair price, was punctual, and while spending more time than he expected, stuck to the original price. Kudos to Michael for getting a tricky job done.

Mike and his team are phenomenal. Very quick to respond and schedule and then more importantly, absolute professionals. Deep cleaned the chimney and made sure they cleaned any residual dust around the area.

They were able to come out next day and fix our gas fireplace issue. They listened to all of our concerns and addressed any questions we had while thoroughly explaining the work that needed to be done. The price was fair and upfront.

Mike set up an appointment for the next day to clean our dryer vent. He maintained good communication the whole time. The technician who arrived was professional and did a thorough job. The price was reasonable too.

FAQ
Exterior Chimney Installation Questions
We start by matching the height and diameter of the chimney to your heat source so the draft pulls smoke up and out. Then we map the run up the exterior wall, set the correct clearances, and plan the penetration point. The chimney is assembled section by section and bolted to sturdy brackets so it stands firm against wind and weather. Every joint, wall pass through, and roofline point is sealed and flashed to keep rain and pests out. Finally we confirm the chimney vents correctly and run a carbon monoxide check before we leave.
Cost depends on the height of the chimney, the type of heat source it serves, wall access and layout, the condition of any existing structure, and finishing details such as custom caps and trim. We give you a free same day estimate with clear up front pricing before any work starts.
Many exterior chimney installations are completed in as little as one day. We confirm the timeline with you during your estimate.
An exterior chimney runs up the outside wall of your home, which is the right choice when there is no clear interior path. It keeps the work outside your living space and is often the faster route for a new chimney installation.
If your chimney is rusted, cracked, leaning, or drafts poorly, a new exterior chimney is often safer than repeated repairs. During your estimate we inspect the structure and give you an honest recommendation.
Because the chimney is built on the outside wall, most of the work stays outside. We protect your home while we work and clean up the area when we finish.
Schedule an annual inspection and sweep, keep the cap clear of debris, and call us if you notice smoke backing up, odors, or water near the fireplace. Regular care keeps your chimney venting safely for years.
We install to code and give you the documentation you need. Just ask during your estimate and we will explain what your home requires.
We offer 24/7 emergency service, so you can reach us when something goes wrong with your chimney.
