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.

AfterMortar Repointing in Queens, NY
Mortar repointing is the process of removing deteriorated mortar from the joints between your chimney’s masonry and replacing it with fresh, weather-resistant mortar that seals the structure against water intrusion. In Queens, most chimneys built before the 1970s need repointing every 20 to 30 years – and many we inspect have joints that are well past that point. If you’ve noticed crumbling, recessed, or missing mortar on your chimney, that’s not cosmetic wear. It’s a water pathway directly into your masonry, your flashing, and eventually your home.
At Hearthstone Chimney Co., we’ve been repointing chimneys across Queens as part of our Chimney Repair services since 1984. Russell Haines built this company on the principle that a repair is only a repair if it holds – which is why every repointing job we do is backed by the 90-Day Done Right Promise, in writing, no arguing. If you’d like a straight answer about what your chimney needs, call us at (516) 531-6315. A live person answers every hour of every day.
Mortar repointing is one of the most common services we perform as part of our broader Chimney Repair in Queens work – and when it’s done right, it extends the life of a masonry chimney by decades.
When You Need Mortar Repointing
Queens chimneys face a specific set of stressors. The borough’s older housing stock – much of it built between the 1920s and 1950s in neighborhoods like Jamaica, Woodhaven, Flushing, and Forest Hills – means original mortar that was mixed by hand and laid without modern admixtures. Freeze-thaw cycles along the Atlantic coast accelerate joint erosion faster than inland areas, and the salt air carried off Jamaica Bay puts additional pressure on exposed masonry. Here’s what to watch for:
- Mortar joints that look recessed or scooped out. Healthy joints should sit flush with the brick face, or slightly angled to shed water. When the mortar recedes more than a quarter inch, water pools there and accelerates further damage with every freeze.
- Crumbling or powdery mortar you can pick out with a key or screwdriver. If the joint material crumbles at light pressure, it’s no longer doing any structural work. We see this frequently in Astoria and Ridgewood on chimneys that haven’t been touched since the original build.
- White staining (efflorescence) on the chimney face. Those chalky white deposits are mineral salts being carried out of the masonry by water moving through failed joints. The stain tells you water is already inside the structure.
- Water marks or staining on interior walls near the chimney. In attached and semi-detached Queens homes, failed mortar joints often show up as water stains on the interior wall adjacent to the chimney – sometimes mistaken for roof leaks.
- Spalling bricks adjacent to open joints. Once water gets behind the mortar line and freezes, it expands and pops the brick face. Spalling bricks next to open joints is a sign that repointing has been overdue for several seasons.
- A chimney inspector’s documented finding from a Level 2 inspection. Our camera inspections frequently reveal mortar deterioration that isn’t visible from the ground, particularly in the upper courses and shoulder areas where water concentrates. We show homeowners the photos before we write a single number on an estimate.
Our Mortar Repointing Process
We don’t patch over old mortar. That approach fails within a season or two because the new material bonds to the deteriorated surface rather than the masonry itself. Our process is thorough because thoroughness is the only thing that makes repointing last.
- Inspection and documentation before any work begins. We start at the top – literally. Russell Haines and our technicians use a Level 2 camera inspection to document the condition of every joint we can see, and we give you photos along with a plain-English assessment of what needs to be done and what can wait. You know exactly what you’re approving before a chisel touches your chimney.
- Careful removal of failed mortar to the correct depth. Old mortar is ground or hand-chiseled out to a minimum depth of three-quarters of an inch – enough to give new mortar a mechanical grip on the masonry. Going shallower than this produces a cosmetic fix, not a structural one. We work carefully to avoid damaging the brick face, which is a real risk in older Queens chimneys where the bricks themselves have softened with age.
- Selection of the correct mortar mix. This is where a lot of contractors get it wrong. Pre-1950s masonry in Queens was typically laid with a soft lime-based mortar. Replacing it with modern Portland cement mortar – which is significantly harder – traps moisture in the bricks and accelerates spalling. We match the mortar mix to the age and type of your masonry. For older chimneys, that generally means a Type N or Type O mortar with the right lime-to-sand ratio. The material has to be compatible with what’s already there.
- Application and tooling of new mortar joints. New mortar is packed into the cleaned joints in layers, tooled to match the original joint profile, and finished to promote water runoff. We work section by section to keep the mortar from setting too quickly in summer heat, which is a real problem during Queens’ July and August days when surface temperatures on a south-facing chimney can reach well above 90 degrees.
- Cleanup and a walk-through with you. We clean the work area, remove all debris, and walk you through what was done – often with the before-and-after photos right there on the tablet. You can see the difference, and you know exactly what was replaced. No mystery, no guesswork.
- Written confirmation of the 90-Day Done Right Promise. Before we leave, you have the promise in writing. If any joint we repointed fails within 90 days under normal conditions, we come back and make it right – no paperwork, no arguing about it.
Mortar Repointing Pricing in Queens
If you’re wondering How Much Does Chimney Repair Cost? (2026 Price Guide) - Queens, NY, mortar repointing in Queens typically runs between $400 and $1,800 for most residential chimneys, with the majority of single-flue repointing jobs falling in the $550 to $950 range. Larger jobs – full chimney rebuilds, double-flue chimneys, or severely deteriorated structures – can run higher. The table below gives a general sense of how cost scales with scope.
| Scope of Work | Typical Range (Queens) |
|---|---|
| Spot repointing (2-4 linear feet of failed joints) | $400 – $550 |
| Single-flue chimney, partial repointing (upper third) | $550 – $800 |
| Single-flue chimney, full repointing | $750 – $1,100 |
| Double-flue chimney, full repointing | $1,000 – $1,500 |
| Repointing combined with crown repair or brick replacement | $1,200 – $1,800+ |
Several factors affect where your job lands in that range:
- Chimney height and roof pitch. Steep roofs are common in older Queens neighborhoods like Forest Hills and Kew Gardens, and working safely at height on a pitched roof takes more time and rigging than a flat or low-slope situation.
- Extent of deterioration. A chimney where the top six courses need attention is a different job from one where the joints are failing on every visible face from the shoulder to the cap.
- Mortar mix requirements. Pre-war masonry in neighborhoods like Richmond Hill or Ozone Park often calls for a softer lime-rich mix that takes more care to source and apply correctly. That’s the right way to do it, and it affects labor time.
- Access considerations. Attached row homes in Jackson Heights or Elmhurst sometimes have limited roof access, which affects setup time.

FAQs – Mortar Repointing
How do I know if my chimney needs repointing or a full rebuild?
If the mortar joints are failing but the bricks themselves are structurally sound – not cracked through, not shifted, not missing – repointing is the correct repair. A full or partial rebuild is necessary when the bricks are damaged beyond surface Spalling Brick Repair can address, when the chimney structure has shifted or leaned, or when more than 30 to 40 percent of the brick faces are deteriorated. Our Level 2 inspection gives you photos and a plain-English answer so you’re not guessing. We’ll tell you exactly which category your chimney falls into before we quote anything. Call (516) 531-6315 and we’ll schedule an inspection at a time that works for you.
How long does mortar repointing last in Queens?
Properly done repointing – using a mortar mix that’s compatible with your existing masonry and applied to the correct depth – should last 20 to 30 years under normal conditions. Queens chimneys face harder use than the national average because of freeze-thaw cycling, coastal humidity, and the age of the housing stock. Chimneys that are repointed with mismatched mortar (usually Portland cement that’s too hard for the original brick) often see failure within five to seven years. We match the mix to the masonry, which is why our work holds.
Can mortar repointing be done in winter in Queens?
It can be done in cooler weather, but fresh mortar cannot be allowed to freeze before it cures – typically for the first 24 to 48 hours after application. We schedule cold-weather repointing carefully and use appropriate admixtures and protective measures when temperatures are marginal. Below about 40 degrees Fahrenheit, we’ll generally recommend waiting for a warmer window rather than compromising the cure. If your chimney has an urgent situation in winter – open joints that are letting water in actively – call us at (516) 531-6315 and we’ll assess whether an immediate repair or a temporary protective measure makes more sense for your situation.
What’s the difference between repointing and tuckpointing?
Repointing and tuckpointing are often used interchangeably, but they’re technically different. Repointing means removing failed mortar and replacing it with new mortar of a matching composition – this is the correct structural repair. Tuckpointing, in the traditional sense, refers to applying two different colors of mortar to create a decorative appearance of very fine joints. Most residential chimney work in Queens is repointing. What matters is that the failed material is fully removed and replaced with the right mix at the right depth – the name matters less than the method.
