Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Our Chimney Repair Services in Harrison
Mortar Repointing
Harrison’s freeze-thaw cycles are relentless on the older brick and limestone chimneys in Purchase. When mortar joints erode, water gets behind the brick and accelerates spalling. We cut out failed joints, pack in new mortar matched to your existing color, and document the before and after with photos. “Repointing” means removing and replacing the outer mortar joints; “tuckpointing” is the finer cosmetic variant, and we do both across Harrison.
Spalling Brick Repair
Spalling is when brick faces pop off, usually from trapped moisture freezing and expanding. We see it constantly on Harrison estate chimneys where the original bricks have endured a hundred Westchester winters. We replace the damaged units, match the color and texture, and address the water entry that caused the spalling in the first place. If we don’t fix the water path, you’ll be calling us again in two years.
Chimney Waterproofing
A chimney that absorbs water is a chimney that will eventually fail. We apply vapor-permeable waterproofing to the masonry after we’ve repaired the joints and crown. On Purchase estate homes off Lake Street, where the stacks run three stories high and masonry is fully exposed to wind-driven rain, we recommend waterproofing as standard practice. It’s a modest cost that extends the life of the entire structure.
Flashing Repair
Flashing failures on Harrison roofs go unnoticed until winter. The gap at the chimney base widens with every freeze-thaw cycle, water seeps in, the brick crown erodes, and the damper assembly rusts. We replace step flashing, counter flashing, and apron flashing with materials sized to your roof pitch. If your chimney’s been leaking into the attic, this is the first thing we check.

Common Chimney Repair Problems We See in Harrison Homes
- Hidden interior spalling in shared estate stacks. A Purchase home with three or four flues sharing one brick stack can develop spalled mortar inside the stack where you can’t see it. Fragments fall and block the smoke chamber, which backs gas or smoke into the next room’s firebox. We scope the full stack on every inspection to find this.
- Flashing failures that only surface in late winter. The gap at the chimney base stays invisible until freeze-thaw widens it enough to let water in. By the time you see a stain on the ceiling, the crown and damper have often been eroding for months. Harrison’s inland climate makes this worse than in Rye or Mamaroneck, where coastal air moderates the freeze cycle.
- Cross-contamination from a neighbor’s appliance vent. In dense village housing where two homes share a chimney stack, a neighbor’s gas appliance vent can push carbon monoxide into an unused but dampered flue on your side. A standard visual inspection misses this; our flue tracing and camera scope finds it.
- Oversized terracotta liners that no longer draft. The original flue tiles in 1920s Purchase estate chimneys were built for coal fires. Modern gas appliances produce cooler exhaust that won’t draft properly through an oversized liner. We see this constantly, and the fix is a correctly sized stainless liner, not another patch.

FAQs - Chimney Repair in Harrison
We run a camera down each flue while marking which damper is open in each room. On older estate stacks where decades of patch repairs by different contractors have left mismatched connections, we use smoke testing and flue tracing to map exactly which firebox connects to which flue, and whether any gas appliance vent has been illegally combined with a wood-burning flue. This diagnostic work is standard on Purchase homes and takes about an hour longer than a basic sweep. Call (914) 350-5204 to have it done right.
No, not as a combined vent. Gas appliance exhaust cannot share a flue with a solid-fuel fireplace unless the gas vent is a separate, isolated liner running in its own flue tile. Many Harrison colonials were set up this way when oil or gas was switched decades ago, and most fail a Level 2 inspection. The fix is usually a dedicated stainless liner for the appliance and a separate flue for the fireplace. The camera will show you exactly what’s happening so you can make an informed call instead of taking our word for it.
Because the original crown was poured with the wrong mix and without expansion joints, and a hundred years of Westchester freeze-thaw has compounded the problem. Every cycle pushes the crack wider. A proper fix means rebuilding the crown with the right concrete mix and installing a custom-fit copper or galvanized cap to keep water off the top entirely. We do this on estate chimneys throughout Harrison, and the crown is part of the photo record you keep when we’re done.
Yes. If your Harrison home shares a chimney stack with a neighboring property and their gas appliance vents into that shared stack, backdrafting can push combustion gases into your unused flue if it’s still dampered but not sealed. This is a carbon monoxide risk, not just a nuisance odor. A Level 2 camera inspection with flue tracing identifies the path of each flue and whether cross-contamination is possible. If you share a wall or stack with a neighbor, this is the inspection you want done this season. Call (914) 350-5204.
Annually, before your first fall fire. Purchase estate chimneys with multiple flues and century-old masonry accumulate creosote unevenly; a flue you never use can still collect debris from the flue next to it. An annual inspection catches spalling, liner cracks, and cross-contamination risks before they become structural repairs. The inspection fee is small compared to what a blocked smoke chamber costs to fix. We’ll write it up with photos and a scope of work, and you decide what gets done when.
