The short answer
You likely need a chimney rebuild when the masonry is crumbling, leaning, or letting water in and simple repairs no longer hold. EverFlame Chimney Care inspects the chimney, takes down the damaged section, and rebuilds it with new brick, mortar, a crown, and flashing, so it is safe to use and sheds water.
A chimney that is leaning, shedding brick, or letting water into the house usually can't be fixed with patching alone. Chimney rebuilding means taking down the damaged section of masonry, often from the roofline up and sometimes further, and laying it back with sound brick, fresh mortar, a new crown, and proper flashing. EverFlame Chimney Care rebuilds chimneys for homeowners in New York City and nearby cities. Our certified technicians first find out how far the damage goes, then rebuild only what needs it. This page explains the warning signs, what the work includes, how we protect your home, and what to expect from start to finish.
Signs you need it
Masonry damage builds slowly. Freeze-thaw cycles, water, and years of flue gases loosen mortar joints until bricks shift or break apart. Many owners first notice the problem from inside the house, not on the roof. If you see any of these, have the chimney inspected before the next time you use it.
- Brick flakes, crumbled mortar, or bits of tile showing up in the firebox
- White, chalky staining on the outside brick, which means water is moving through the masonry
- Water pooling in the firebox or damp stains on the walls and ceiling near the chimney
- Poor draft or smoke rolling back into the room, which can mean a blocked or collapsing flue
- A smoky or creosote smell that hangs in the room even when the fireplace is cold
- A chimney that visibly leans, has open gaps in the mortar, or is missing bricks near the top
What's included
Every rebuild is sized to the damage we find, but the core work stays the same. Before any work starts, we tell you in writing which items apply to your chimney.
- Cleaning the flue with rotary brushes so the liner and masonry can be properly seen
- Camera inspection of the flue to check for cracks, gaps, and hidden damage
- Careful teardown of damaged brick down to solid, sound masonry
- Rebuilding with brick matched as closely as practical to your existing chimney
- Fresh mortar joints that are tooled to shed water
- A new chimney crown that is sloped and overhangs the brick so water drips clear of the face
- New or resealed flashing where the chimney meets the roof
- Relining the flue or replacing flue tiles where the existing liner is damaged
- Installing a chimney cap to keep out rain, debris, and animals
- Clearing all debris from the site, plus a final walkthrough with photos
How our crew works in your home and on the roof
Inside, we lay drop cloths from the door to the fireplace before we bring in any tools. We seal the fireplace opening and run HEPA vacuums during the flue cleaning, so soot and mortar dust stay out of your living space. We use rotary brushes to clean the flue walls, then send a camera up the flue. That lets us see cracked tiles, open joints, and gaps that you can't spot from the firebox. You can view the footage with us.
On the roof, we set up safe access and protect shingles and gutters from falling material. We take bricks down by hand rather than letting them drop, and we lower debris to the ground in containers. When the new masonry goes up, we keep it covered in bad weather while the mortar cures. Before we leave each day, we make sure the open flue is protected from rain.
The standard we follow
We work to NFPA 211, the national standard for chimneys, fireplaces, and vents. It calls for these systems to be inspected once a year. Chimney professionals use three inspection levels. Level 1 is for systems where nothing has changed. Level 2 applies when the system changes, for example when a new appliance is added or you switch fuels, or when the home is sold. Level 3 is used when a hidden hazard can only be reached by opening part of the chimney or building. Rebuilding work usually calls for at least a Level 2 inspection, and sometimes Level 3 once we open the masonry.
For New York City buildings converting a boiler from oil to gas, the chimney has to be evaluated as part of that work. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue. If you're planning a conversion, it makes sense to look at rebuilding and relining at the same time.
What affects the price
We price each rebuild after we inspect it, because no two chimneys need the same amount of work. These are the main factors that move the cost up or down:
- Height of the chimney and how hard the roof is to reach safely
- How much of the chimney has to come down, whether the top few courses or down to the roofline and below
- Fuel type, since wood, oil, and gas each place different demands on the flue and liner
- Flue size and condition, and whether you need a new liner
- How much creosote or soot buildup has to be cleaned before the inspection
- Whether you need a camera inspection, a deeper Level 3 inspection, or added repairs to the crown, flashing, or cap
How a visit works
First, we schedule an inspection. A technician cleans the flue, runs the camera, and checks the masonry from the roof and the firebox. You get photos, a plain explanation of what we found, and a written scope of work. That scope separates what needs attention now from what can wait.
Once you approve the work, we schedule the rebuild. Small rebuilds at the top of a chimney can often be finished in a short visit. Larger rebuilds take longer and depend on the weather, since mortar needs the right conditions to cure. In New York City, heat season runs from October 1 through May 31, so many owners plan bigger masonry work for the warmer months when the chimney is used less. When we finish, we walk you through the work and show you the completed chimney.
