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 New City, NY
Mortar repointing is the process of cutting out deteriorated mortar joints between chimney masonry and packing them with fresh, properly matched mortar – restoring the weathertight bond that holds your chimney together. In New City, where freeze-thaw cycles hit hard from November through March and humidity off the Hudson Valley keeps masonry damp well into spring, mortar joints take a beating that most homeowners don’t notice until the damage is well advanced. The good news is that repointing, done at the right time and with the right material, is one of the most cost-effective our Chimney Repair services available.
At Hearthstone Chimney Co., we’ve been doing this work since 1984 – over 42 years of New City chimneys, Rockland County winters, and mortar mixes that hold. If your chimney’s joints are crumbling, cracked, or pulling away from the brick, call us at (845) 599-0930. A live person answers every call, day or night, and we’ll get a uniformed technician out to take a look. Every job is covered by our 90-Day Done Right Promise – in writing, no arguing. As part of our broader Chimney Repair in New City services, repointing is one of the repairs we complete most often, and we treat it with exactly that level of care.
Russell Haines leads our crew here, and his position is straightforward: mortar is the mortar of a chimney’s structural integrity, and cutting corners on material or preparation is how a $600 repair turns into a $6,000 rebuild five years later. We use professional-grade products from suppliers like Olympia Chimney and Copperfield – nothing off the hardware-store shelf that won’t hold through a Rockland County winter.
When You Need Mortar Repointing
Mortar joints don’t fail all at once. They erode slowly, and by the time the problem is visible from the ground, the damage is often more extensive than it looks. These are the signs we see regularly on New City homes:
- Crumbling or recessed joints. If you can press a fingertip into the mortar between bricks and it crumbles away, the joint has lost its structural bond. On older colonials in the Clarkstown neighborhoods north of New City, we find this on chimneys that haven’t been looked at in 20-plus years.
- Visible gaps or voids between bricks. Gaps wider than a quarter-inch allow water to enter the chimney’s interior. Water in the masonry expands when it freezes, which widens the gap further – a cycle that accelerates every winter.
- Efflorescence – white salt staining on the brick face. That chalky white residue is a reliable indicator that water has been moving through the masonry. The mortar joints are almost always the entry point.
- Staining or moisture on interior walls near the fireplace. When water works its way through failing mortar into the chimney structure, it often shows up as discoloration on the wall or ceiling beside the fireplace before homeowners ever think to look at the chimney itself.
- Mortar dust or small brick chips in the firebox. Material falling into the firebox from above is a direct sign that joints or the crown are deteriorating. In New City homes with older chimneys, this often appears after the first cold snap of the season.
- A chimney that hasn’t been inspected in more than five years. Mortar erosion is gradual and easy to miss without a close look. Our Level-2 camera inspections document the condition of the joints with photos you can see for yourself – no guesswork, no taking our word for it.
Our Mortar Repointing Process
Repointing done right is methodical work. The steps below are what we follow on every job – no shortcuts because the homeowner can’t see the prep work from the ground.
- Inspection and documentation. Before we touch the mortar, we assess the full chimney – joints, crown, cap, flashing, and interior flue. We photograph what we find and show you the images. You get a plain-English explanation of what’s failing, what’s holding, and what we recommend. If repointing is all that’s needed, we’ll tell you so. If there’s additional damage, you’ll know before we quote anything.
- Joint preparation. Old, failed mortar is cut back to a minimum depth of 3/4 of an inch – sometimes deeper if the damage extends further in. This is the step that determines whether the new mortar bonds correctly. Under-cutting is the most common reason a repointing job fails prematurely. We use angle grinders and chisels appropriate to the joint width and brick age, taking care not to damage the brick face.
- Mortar matching. Matching the new mortar to the existing masonry matters more than most homeowners realize. Using a mortar that’s too hard for older, softer brick causes the brick itself to crack – the mortar should be slightly softer than the brick, so stress fractures form in the joint, not the unit. We assess the original mortar type and mix or select a material that suits the chimney’s age and brick composition.
- Repointing the joints. New mortar is packed firmly into the prepared joints in layers, tooled to match the original joint profile, and finished to create a tight, weatherproof bond. We work systematically so no joint is skipped or half-filled.
- Cleanup and final inspection. We remove debris from the work area, check the finished joints for voids or surface defects, and do a final walk-around before we consider the job done. Most repointing jobs in New City are completed in a single visit. If the chimney is large or the damage extensive, we’ll tell you upfront before we schedule.
- Post-job documentation. Before we leave, we provide photos of the finished work and a written record of what was done. The 90-Day Done Right Promise is attached to every job – if something isn’t right, we come back and fix it. No paperwork, no arguing, no runaround.
Mortar Repointing Pricing in New City
How Much Does Chimney Repair Cost? (2026 Price Guide) - New City, NY for mortar repointing in New City typically runs between $300 and $1,500 for most residential chimneys, depending on the chimney’s size, the extent of joint deterioration, and access conditions. A standard two-story colonial with moderate joint erosion on the exposed upper courses generally falls in the $400 to $700 range. Chimneys that haven’t been touched in 30 or more years, or those with significant deterioration on multiple faces, can run higher.
| Scope of Work | Typical Price Range |
|---|---|
| Minor repointing (upper courses only, good access) | $300 – $500 |
| Moderate repointing (full chimney, standard height) | $500 – $900 |
| Extensive repointing (multi-face, deep joint damage) | $900 – $1,500+ |
| Repointing combined with crown repair | $700 – $1,800 |
Several factors shift that number in one direction or the other:
- Chimney height and roof pitch. New City has no shortage of steep-pitched roofs, particularly on the older homes near South Mountain Road and along the western edges of town. Higher chimneys and steeper pitches require more setup time and appropriate fall protection, which affects labor cost.
- Joint depth and brick condition. When deterioration has gone deep, or when the brick around the joints has spalled or cracked, the prep work takes longer and the repair may involve more than just mortar.
- Whether additional repairs are needed at the same visit. Crown repairs, cap replacement, or flashing work can often be done in the same visit, which saves you mobilization costs versus scheduling separate trips.
- Age of the chimney. Pre-1950 chimneys, which are common in older New City neighborhoods, sometimes used lime-based mortars that require specific matching to avoid damaging the original brick.

Why New City Homeowners Choose Hearthstone
We’re not the company that drops a price on the phone without seeing the chimney. And we’re not the outfit that shows up in an unmarked van and pressures you into a larger job than you need. Hearthstone has been operating in this area since 1984, which means we’ve seen what happens to chimneys over 20, 30, and 40 years of Rockland County weather – and we know the difference between a chimney that needs repointing today and one that can wait another season.
Every technician who comes to your home is background-checked and uniformed. They carry the materials to complete most jobs the same day. When Russell Haines puts his name on a job, the 90-Day Done Right Promise goes with it – if the work isn’t right, we come back and make it right, in writing, without an argument. That’s not a sales pitch. That’s been the standard since the beginning.
We work exclusively with professional-grade materials. Olympia Chimney and Copperfield supply products engineered for chimney-specific applications, built to handle the thermal cycling and moisture exposure that a residential chimney sees year after year. The mortar we use is chosen for its compatibility with your specific masonry – not because it was the cheapest option at a supply house.
New City’s climate is not gentle on masonry. The temperature swings between January and April alone are enough to open microcracks in even healthy mortar. Chimneys on the north face of a home – common on the larger lots east of New City Road – hold moisture longer and tend to show joint failure earlier than those with better sun exposure. We factor those conditions into our assessment and our material choices, because a repair that ignores the environment it’s working in won’t last.
If you’ve been thinking about having your chimney looked at, or if someone told you the mortar needs attention and you want a second opinion, we’re straightforward to reach.

FAQs – Mortar Repointing
How do I know if my chimney needs repointing or a full rebuild?
Repointing is the right repair when the bricks themselves are structurally sound and only the mortar joints have deteriorated. A full or partial rebuild becomes necessary when the bricks are cracked, Spalling Brick Repair badly, or when the chimney’s structural integrity has been compromised by years of water intrusion. In New City, we see a lot of chimneys where the joints are the problem and the brick is still solid – those respond very well to repointing alone. The honest answer to which one you need comes from a close-up inspection, not a ground-level assessment. Our Level-2 camera inspection gives us and you a clear picture of what’s actually happening inside and outside the chimney, with photos to show for it. Call (845) 599-0930 for a free estimate and we’ll give you a plain-English verdict.
How long does repointed mortar last in New City’s climate?
Properly done repointing with correctly matched mortar should last 20 to 30 years under normal conditions. In New City’s climate, where freeze-thaw cycles are significant and chimneys on north-facing or heavily shaded exposures stay damp longer, 20 years is a reasonable expectation for well-executed work. Shortcuts in preparation – especially cutting the old mortar back too shallow – are the primary reason repointing fails in less than a decade. We cut to the required depth every time, because the prep work is what determines how long the repair holds.
Is mortar repointing something a homeowner can do themselves?
Some homeowners attempt repointing on low, accessible sections of a chimney, and with the right materials and careful prep, minor spot repairs at ground level can hold reasonably well. But chimney repointing at height involves working on a pitched roof, which carries real fall risk and requires appropriate safety equipment – it’s not a ladder-and-caulk situation. Beyond the safety issue, mortar matching is genuinely technical: using a Portland-cement mix that’s harder than the surrounding brick on an older chimney will cause the brick faces to crack over time, creating a worse problem than the one you started with. For the upper courses of any chimney, and for any chimney on a two-story or taller home, we’d recommend leaving it to a trained technician.
Does repointing also fix my chimney’s leaking problem?
Failed mortar joints are one of the most common entry points for water in a chimney, so repointing often resolves leaking that started at the joints. But a leaking chimney can have multiple causes – a cracked or open crown, failed flashing at the roof line, a missing or ill-fitted cap, or a deteriorated liner. When we inspect a chimney in New City that’s been leaking, we look at all of those before attributing it to the joints alone. Repointing the joints while the crown is cracked, for example, will reduce but not eliminate water intrusion. Our process covers the full chimney at inspection so we’re recommending a repair that actually solves the problem, not just part of it. Call (845) 599-0930 and we’ll come out and give you a complete picture.
