"Damper was rusted shut for years. Fixed in one visit, and they showed me photos of the old one for comparison."
"Repaired brick matched the existing chimney so well you can't tell where the work was done."

Why Manhasset Hills Chimneys Need Repair Work
Most chimneys in Manhasset Hills are original to homes built in the late 1950s and early 1960s. Sixty-plus years of freeze-thaw cycles, water exposure, and settling brick take a toll that isn't always obvious from the ground — a hairline crack in the crown today is a soaked, spalling chimney chase in five years if it's left alone.
We don't quote a fix until we know the actual cause. A cracked crown, a failing flashing seal, and rising damp from a bad liner can all look similar from the outside but need completely different repairs — get the diagnosis wrong and the "fix" doesn't hold.

Signs Your Chimney Needs Repair
Any of these mean it's time for an assessment, not a wait-and-see approach.
- White staining (efflorescence) on the brick
- Crumbling or missing mortar between bricks
- Visible cracks in the crown or chimney cap
- A damper that's rusted, stuck, or won't seal properly
- Bricks that are flaking, chipping, or spalling
- Water stains on the ceiling or wall near the chimney
Common Chimney Repairs We Handle
Crown Repair & Rebuild
The crown sheds water off the top of the chimney — a cracked one is the fastest route to major interior water damage. We patch minor cracks or pour a full reinforced crown with a proper drip edge.
Masonry & Tuckpointing
Failed mortar joints removed and repacked so water stops getting behind the brick. Spalling or cracked brick repaired to match your chimney's existing look and structure.
Damper Repair & Replacement
Rusted, stuck, or poorly sealing dampers replaced — including top-sealing dampers that cut drafts and keep rain and animals out between fires.
Flashing Repair
Flashing is where most roof-related chimney leaks start. We reseal or replace it so water stops finding its way into your attic.
Smoke Chamber Repair
Parging and resurfacing deteriorated smoke chambers so smoke and gases stay in the flue instead of your living space.
Structural Rebuilding
For chimneys with real structural failure — leaning stacks, extensive brick deterioration — we rebuild from the roofline up.
Our Diagnose-First Process
Full Diagnostic Inspection
We find the actual cause, not just the visible symptom — a crack up top can mean several different problems underneath.

Frequently Asked Questions
Most issues — cracked crowns, failing mortar, damaged flashing — are repairable without a full rebuild. A rebuild is only needed for real structural failure, like a leaning stack or brick deterioration throughout the structure. We'll tell you honestly which one your chimney actually needs.
Water gets in through the crack, then freezes and expands in winter, widening the damage every season. What starts as a small crack can turn into a fully deteriorated crown, water damage inside the chimney chase, or interior ceiling stains within a few years.
We match brick and mortar color as closely as possible so repairs blend in rather than stand out. On older Manhasset Hills homes with original brick, we'll walk you through what's achievable before starting.
Most repairs — crown patching, mortar joints, damper replacement — are completed in a single visit. Larger jobs like a full crown rebuild or masonry rebuild may take one to a few days depending on scope and weather.
It depends on the cause and your specific policy — sudden damage (like a storm) is often covered, while gradual deterioration from age typically isn't. We can provide photo documentation to support a claim either way.
Pricing depends entirely on what's actually wrong and how extensive the damage is, so we quote it after a proper diagnosis rather than off a generic list. Get in touch and we'll give you a straight number before any work starts.
