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 Cherry Hill, NJ
Mortar repointing is the process of removing deteriorated mortar from the joints between chimney masonry and packing in fresh, correctly mixed mortar to restore a weathertight seal. In Cherry Hill, where freeze-thaw cycles run through December, January, and February with little mercy, failing mortar joints are the single most common masonry problem we find on inspection – and one of the most straightforward chimney repair to fix when caught before water gets behind the brick. If you’re seeing crumbling white lines between your bricks, efflorescence streaking down the chimney face, or small chunks of mortar on the roof or in the firebox, call us at (856) 543-2929 and we’ll tell you exactly what you’re dealing with, at no charge to look.
Hearthstone Chimney Co. has been repointing chimneys in Cherry Hill and across South Jersey since 1984 – over 42 years of work on everything from mid-century colonial brick stacks in Erlton to newer masonry in Springdale and the older Cape Cods scattered through Barclay Farm. Russell Haines built this company on the idea that mortar work done halfway fails within a few years, so every repointing job we do follows the same careful process and carries our 90-Day Done Right Promise in writing. If something isn’t right, we come back. No paperwork, no arguing. Our Chimney Repair in Cherry Hill page covers the full scope of masonry and liner work we do, but this page is specifically about repointing – what it involves, what it costs here in Cherry Hill, and how we do it.
What Mortar Repointing Actually Does
Mortar is not decorative. Those joints between courses of brick are the structural connective tissue of your chimney stack, and they do two jobs simultaneously: they hold the masonry assembly together, and they shed water away from the brick face. When mortar degrades – and all mortar eventually does – it begins to pull away from the brick edges and erode inward. That erosion creates channels where rainwater can travel directly into the chimney core.
Cherry Hill sits in a climate zone where ground temperatures regularly drop below 32 degrees multiple times per winter. Water that has soaked into a shallow mortar joint expands when it freezes, widening the gap. The next thaw draws in more water, and the cycle repeats. Within a few seasons, a joint that started with minor surface erosion can open up enough to admit water in quantity. That water migrates down through the chimney structure, saturates the surrounding masonry, and eventually finds its way into the firebox, the smoke chamber, or the adjacent wall framing. In older homes in sections like Woodcrest or Kingston, where original brick and mortar may date to the 1950s and 1960s, this progression often happens quietly over years before the homeowner notices anything obvious inside the house.
Repointing stops that progression. The compromised material is removed to a consistent depth, and fresh mortar – matched in composition and flexibility to the original masonry – is packed into the cleaned joint so it bonds properly on both surfaces and seals the channel against water entry.
When You Need Mortar Repointing
- Mortar joints are recessed more than a quarter inch from the brick face. This is the clearest diagnostic indicator. When you run a finger across the joint and it sinks noticeably below the brick surface, the mortar has shrunk or eroded enough to break its seal with the brick edge, and water now has a direct path inward.
- You’re finding mortar debris on your roof or in the firebox. Spalling and crumbling mortar falls as the joints fail. Chunks on the roof flashing or in the firebox opening usually mean the deterioration is active and has been progressing for at least one or two full freeze-thaw seasons.
- White staining or efflorescence is running down the chimney face. Efflorescence is the salt residue left behind when water moves through masonry and evaporates on the surface. It’s a reliable sign that water has been traveling through the mortar joints on a regular basis.
- Bricks are beginning to spall or flake at the faces. When water repeatedly saturates brick and freezes inside the material itself, the face of the brick pops off in thin layers. This is a sign that mortar failure has already allowed enough water intrusion to begin damaging the brick units, not just the joints.
- You notice damp spots or staining on a wall or ceiling near the fireplace. Moisture that enters through deteriorated mortar joints above the roofline can travel several feet down through the chimney structure before appearing inside. If you see staining on a ceiling or a wall adjacent to the firebox, failing mortar is a primary suspect.
- Your chimney is more than 20 years old and has never had a mortar inspection. This is common in Cherry Hill’s established neighborhoods. Mortar formulated before the mid-2000s was often harder and less flexible than modern mixes – it tends to crack under thermal cycling rather than flex with it. If your chimney predates a major renovation and has never been looked at, it’s worth knowing where the joints stand before the next winter.
Our Mortar Repointing Process
There’s no shortcut in repointing that doesn’t show up as a callback within two or three years. We’ve seen the shortcuts – mortar brushed over old joints without any removal, mismatched mix ratios that crack before the first winter, joints filled without cleaning the dust and loose material that prevents bonding. Our process takes longer than those approaches. It also holds.
- Level-2 camera inspection and photo documentation before any work begins. We inspect the full chimney system – cap, crown, joints, liner, smoke chamber, and firebox – with camera equipment and photograph every finding. You see the same images we see, and we give you a plain-English description of what’s there. This matters because repointing the exterior joints while ignoring crown deterioration or a failed liner cap just means the water finds a different path. We treat the system, not just the visible surface.
- Joint preparation: mechanical removal of compromised mortar to a consistent depth. We grind or chisel out failing mortar to a minimum depth of three-quarters of an inch – enough to give fresh mortar a surface to bond to on both brick faces. Anything shallower than that is a cosmetic patch, not a repair. We clear all dust and loose debris from the joint before any new mortar goes in.
- Mortar mix selection matched to the original masonry. This step is where a lot of repointing work goes wrong. Modern high-Portland mortar mixed for new construction is significantly harder than the brick it’s applied to in most older Cherry Hill homes. When mortar is harder than the brick, thermal movement cracks the brick face rather than the joint – which is far more expensive to fix. We match the mortar formulation to the original masonry: lime content, compressive strength, and finish texture. For chimneys where the original specification is unknown, we test the existing brick hardness before mixing.
- Packing and tooling the new joints. Fresh mortar is packed in layers for deep joints and tooled to match the original joint profile – typically a concave or weathered joint for exterior chimney masonry. Proper tooling compresses the mortar surface against both brick edges and encourages water runoff rather than pooling. We work in manageable sections so no mortar dries before it’s properly tooled.
- Curing and inspection. Mortar needs time to cure correctly, and curing conditions matter. We account for temperature and humidity on the day of the job. If conditions aren’t right for proper cure – temperatures below 40 degrees or above 90 degrees, or rain in the forecast – we reschedule rather than rush work that needs a controlled cure to bond correctly. After curing, we inspect the completed joints and document the finished work with photographs.
- Final walkthrough and written closeout. Russell Haines built our process around the idea that the homeowner should leave every job understanding what was done and why. We walk you through the finished work, explain what to watch for over the next season, and hand you written documentation of the work completed and the 90-Day Done Right Promise that backs it. In writing. No arguing.
Mortar Repointing Pricing in Cherry Hill
Mortar repointing in Cherry Hill typically runs between $300 and $2,500 depending on the scope of the work. Most single-flue residential chimneys with moderate joint deterioration fall in the $400 to $900 range. A full repoint of a tall two-flue stack with significant erosion on multiple faces can reach $1,500 or more. The estimate is free, and the number on the estimate is the number on the invoice – no surprises.
| Scope of Work | Typical Range |
|---|---|
| Spot repointing – isolated joint failure, 1 or 2 courses | $300 – $500 |
| Partial repoint – one or two faces of single-flue chimney | $500 – $900 |
| Full repoint – all four faces, single-flue chimney | $800 – $1,400 |
| Full repoint – two-flue or oversized chimney stack | $1,200 – $2,500 |
| Repointing combined with crown repair or cap replacement | $900 – $2,200 |
What Affects the Cost
- Height and access. A chimney stack that requires ladder extension beyond standard residential height, or that sits on a steep-pitch roof common in some of Cherry Hill’s older split-levels and two-story colonials, takes longer to work safely and may require scaffolding. We’ll tell you upfront if the access situation changes the price.
- Extent of joint deterioration. Light surface erosion on a few courses is a half-day job. Deep erosion across multiple faces that requires full mechanical removal and multi-layer packing takes considerably more time and material.
- Mortar specification complexity. Chimneys built before 1980 – common in sections like Erlton Woods and Downs Farm – sometimes require lime-based mortar formulations that take more preparation time than standard mixes. The material itself is not expensive, but the specification work is not a corner we cut.
- Combined repairs. If inspection shows that crown deterioration or cap failure contributed to the mortar damage, addressing those at the same visit is almost always more efficient than separate mobilizations. We’ll show you the photos and let you decide.
We currently offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans. If you have a written estimate from another company, we’ll give you a free second opinion before you commit to anything.

FAQs – Mortar Repointing
How long does mortar repointing last?
Properly done repointing using a correctly matched mortar mix typically lasts 25 to 40 years on a residential chimney in a climate like Cherry Hill’s. The lifespan depends heavily on mortar specification – mortar that is too hard for the brick it’s bonded to will crack within a few years as the masonry flexes through seasonal temperature changes. That’s why we match the formulation to the existing brick rather than using whatever’s convenient. A repoint done right should outlast the next two or three owners of the house. Call (856) 543-2929 if you want to know where your chimney stands.
Can I repoint just part of the chimney, or does it all need to be done at once?
Spot repointing is entirely appropriate when deterioration is genuinely isolated – a few joints in one area that show active erosion while the rest of the chimney is in reasonable condition. We’ll photograph the full chimney during inspection and tell you honestly which joints are failing and which are holding. If only one face needs work, we’re not going to tell you it all needs to be done. What we won’t do is patch a few visible joints and walk away from active erosion two feet away that you can’t see from the ground.
Is mortar repointing something a homeowner can do themselves?
Cosmetic tuck-pointing on a ground-level garden wall is a reasonable weekend project. Chimney repointing is different for two reasons. First, working at chimney height on a sloped roof is genuinely dangerous, and a fall from that height is a life-altering event – we handle the height work so you don’t have to. Second, chimney mortar specification matters in a way it doesn’t for garden walls: the wrong mix ratio will crack or damage the brick within a few seasons, and the repair costs more than the original repoint would have. We’ve corrected DIY repoints in Cherry Hill where every joint was done with hardware store mortar that was too hard for the original brick, and the brick faces began to spall within two winters.
How do I know if my chimney needs repointing or a full rebuild?
Repointing addresses failing mortar joints while the brick units themselves remain structurally sound. A rebuild becomes necessary when the brick faces are extensively spalled, when sections of the stack have shifted or separated, or when mortar failure has progressed to the point where the structural integrity of the chimney assembly is compromised. The line between the two is not always obvious from the ground. Our Level-2 camera inspection documents the actual condition of every component – brick, joints, crown, liner, and smoke chamber – and gives you a clear answer with photographs you can see. If it needs a rebuild, we’ll show you why. If repointing will handle it, we’ll say that instead. Call (856) 543-2929 and we’ll schedule a look.
Why Cherry Hill Homeowners Call Hearthstone
Over 42 years of work in South Jersey means we’ve repointed chimneys on nearly every street type Cherry Hill has – the wide-lot colonials off Kresson Road, the older brick two-stories near Cherry Hill East, the split-levels and ranches in Barclay Farm where chimneys often run through interior walls and water intrusion is harder to trace. We know what the local climate does to mortar over time, and we know what the original construction in this area typically used for mortar formulation. That context matters when you’re matching a mix to 1960s brick.
Russell Haines leads every job under the same standard: document everything, match the materials correctly, do the work once, and stand behind it in writing. We use professional-grade materials from brands like Olympia Chimney and Copperfield – not builder-grade substitutes – because the difference in material quality shows up over the life of the repair, not the day of installation. Background-checked, uniformed technicians handle the field work, and most repointing jobs are completed in a single visit. The phone is answered by a live person every day of the week, every hour of the day.
