Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Mortar Repointing in Hicksville, NY
Mortar repointing is the process of cutting out cracked, crumbling, or missing mortar joints in a chimney’s masonry and replacing them with fresh, properly mixed mortar – restoring the structure’s ability to shed water and carry the load of the flue above. In Hicksville, most chimneys built between the 1950s and 1980s are now showing exactly this kind of joint deterioration, and a repointing job done right can add two or three decades to the life of the masonry before anyone needs to think about a full rebuild. If you’re seeing white streaks on the brick, gaps you can press a finger into, or mortar dust in the firebox, call us at (845) 757-0998 – a live person answers every call, day or night.
We handle mortar repointing as part of our broader Chimney Repair in Hicksville services, and we treat it as the skilled masonry work it actually is – not a caulk-gun job, not a patch-and-pray approach. Russell Haines and the Hearthstone Chimney Co. team have been repointing chimneys on Long Island since 1984. We know what mortar mix works in a climate that swings from 95-degree August heat to single-digit February wind chills, and we know the difference between a joint that needs cleaning and filling versus one that signals a deeper structural problem the homeowner needs to hear about plainly.
Every repointing job we complete is covered by our 90-Day Done Right Promise – in writing, no arguing. If something isn’t right, we come back and make it right. That’s not a slogan. It’s how we’ve kept the phone ringing in Hicksville for over 42 years.
When You Need Mortar Repointing
The tricky part about mortar deterioration is that it moves slowly enough that most homeowners don’t notice until the problem is well along. Here are the signs we see regularly on Hicksville chimneys that tell us repointing is overdue:
- Mortar joints you can dig into with a key or screwdriver. Healthy mortar is hard and unyielding. If you can crumble or scratch it out easily, the joint has lost its compressive strength and water is already getting in.
- White staining (efflorescence) on the chimney’s exterior brickwork. That chalky residue is mineral salt left behind as water migrates through the masonry and evaporates. It’s a reliable indicator that the mortar joints are no longer keeping water out.
- Visible gaps or voids between bricks. Once mortar has receded more than a quarter inch below the face of the brick, water pools in the joint with every rain. On Hicksville’s older Cape Cods and split-levels – where chimneys sit exposed above the roofline for six feet or more – that pooling accelerates freeze-thaw spalling quickly.
- Mortar dust, chips, or small chunks in the firebox. Material falling from the joints inside the flue means the deterioration has reached the interior courses. That’s worth having looked at before the next burning season.
- Staining or moisture on interior walls or ceilings near the fireplace. Water tracking into the living space via failed mortar joints can travel several feet before it shows up as a stain. We’ve traced ceiling damage in South Farmingdale-adjacent homes back to repointing failures on the exterior chimney two stories above.
- A chimney that’s simply old. Mortar on Long Island chimneys installed before 1975 was often mixed with a high lime content that softens faster than modern blends. If the chimney hasn’t been repointed since it was built, it’s probably overdue regardless of what you can see from the ground.
Our Mortar Repointing Process
There’s a right way to repoint a chimney and a fast way. The fast way – skimming new mortar over old deteriorated joints without cleaning them out – fails within a few years because the new mortar has nothing solid to bond to. We don’t do it that way. Here’s what a repointing job with Hearthstone Chimney Co. actually looks like:
- Inspection and documentation before any tools come out. We start with a thorough visual inspection of every accessible course, and on jobs where the interior flue condition is uncertain, we run a Level-2 camera inspection so we have photos of what’s happening inside the masonry as well as out. You’ll see the same photos we see, and you’ll get a plain-English explanation of what they show – not a list of repairs we hope you’ll approve.
- Removing deteriorated mortar to the correct depth. We grind or chisel out old mortar to a minimum depth of three-quarters of an inch – sometimes deeper where the joint is fully compromised. This is the step that separates a lasting repair from a cosmetic one. Rushing this stage is where a lot of repointing jobs fail.
- Cleaning and prepping the joint. After grinding, the joint is blown clean of dust and debris. On Hicksville chimneys that have been repointed before, we sometimes find mismatched mortar from a previous contractor layered over the original. We remove it. Adhesion depends on a clean, dry surface, and we don’t skip that step.
- Mixing and applying the correct mortar formulation. Not all mortar is the same, and the wrong type can actually damage older brick by being harder than the masonry itself – forcing freeze-thaw stress into the brick face rather than the joint. We match the mortar mix to the age and composition of the existing masonry, using professional-grade materials including products from Copperfield and Gelco where applicable. The mortar is packed in layers and tooled to match the original joint profile.
- Final inspection and cleanup. Once the mortar has set sufficiently, we inspect every joint we’ve touched, confirm the profile is consistent, and clean mortar smear from the brick faces. We leave the work site the way we found it, and we walk you through what was done before we go.
- Written documentation and guarantee. The 90-Day Done Right Promise is issued in writing at job completion. If a joint opens, cracks, or fails to bond within 90 days, we return and correct it. No paperwork, no disputing – just the repair made right.
Mortar Repointing Pricing in Hicksville
Mortar repointing in Hicksville typically runs between $400 and $2,200 for a standard residential chimney, depending on the scope of work. That range is wide because the variables genuinely matter: how many linear feet of joint need replacement, how accessible the chimney is, how deep the deterioration runs, and whether the job requires scaffolding or a lift to reach upper courses safely.
| Scope of Work | Typical Price Range |
|---|---|
| Minor repointing (isolated sections, easy access) | $400 – $700 |
| Moderate repointing (several courses, standard two-story access) | $700 – $1,200 |
| Full chimney repointing (all exterior courses, chimney above roofline) | $1,200 – $2,200 |
| Add: Level-2 camera inspection (if flue condition is uncertain) | +$150 – $250 |
| Add: Scaffolding or lift rental for tall or complex chimneys | +$200 – $450 |
A few things affect where your job lands in those ranges. Hicksville’s housing stock is dense with post-war construction – many of those chimneys are two-flue designs with significant above-roof exposure, which means more linear footage and sometimes more complicated access than a single-flue chimney set lower on the roofline. We also factor in whether we find previous patch work that needs to be removed before new mortar can bond properly; that adds time.
What won’t change between the estimate and the invoice is the number on the estimate. Our upfront pricing means we quote the job, and that’s the job we charge for. If we find something additional once we’re into the work – a cracked crown, a compromised flue tile – we stop and show you before we proceed. You decide. No surprises on the bill.

Why Hicksville Homeowners Call Hearthstone Chimney Co.
Hicksville sits in Nassau County’s older housing belt, where a large share of homes were built in the two decades after World War II. A lot of those chimneys have original mortar that has never been touched. The freeze-thaw cycle on Long Island is particularly hard on mortar joints – temperatures cross the freezing mark repeatedly each winter, and water trapped in a deteriorated joint expands and contracts with each cycle, widening the gap a little more each time. By the time a homeowner notices something is wrong, a joint that started as a hairline crack is often a quarter-inch void running the full height of the chimney.
We’ve been working in Hicksville long enough to know which neighborhoods have the most exposure issues. Homes on the north-facing side of streets off Old Country Road and Broadway tend to hold moisture longer through winter, and chimneys on those properties typically show joint deterioration earlier than south-facing ones a block away. That’s the kind of detail you get from 42 years of working in one area.
Russell Haines built Hearthstone Chimney Co. on a straightforward premise: do the work correctly, document it, and stand behind it. The 90-Day Done Right Promise exists because that’s how craftsmen used to do business, and it still works. Our technicians are background-checked and uniformed, they show up when we say they’ll show up, and most repointing jobs are completed in a single visit so you’re not waiting around for a second appointment to finish what the first one started.
We’re part of the broader our Chimney Repair services Hearthstone Chimney Co. provides across Long Island – from chimney cleaning and sweeping to crown repair, liner replacement, and full masonry rebuilds. Whatever the camera inspection turns up, we can handle it, and we’ll explain it to you in plain language before we touch anything.
FAQs – Mortar Repointing
How long does mortar repointing last on a Hicksville chimney?
A properly done repointing job on a Hicksville chimney typically lasts 20 to 30 years, sometimes longer if the chimney cap is in good condition and keeping water off the crown. The two factors that shorten that lifespan are using the wrong mortar type for the existing brick and skipping the joint cleaning step so new mortar bonds to dust and old material rather than solid masonry. We’ve repointed chimneys in Old Bethpage and Westbury that were still in good shape 25 years later because the original work was done right. If you want an honest assessment of where your chimney stands, call us at (845) 757-0998 – estimates are free.
Is repointing a chimney something a homeowner can do themselves?
Mixing and applying mortar at ground level is within reach for a skilled DIYer, but chimney repointing involves working at height on a pitched roof, often above a two-story roofline – and that’s where the risk becomes serious. Beyond the fall hazard, choosing the wrong mortar hardness for your brick type is a common mistake that can cause the brick faces themselves to spall over time. We’d rather quote you a fair price on a job done right than see someone get hurt or have a repair fail in three years. Call us for an estimate before you decide.
How do I know if my chimney needs repointing or a full rebuild?
Repointing addresses the mortar joints between bricks – it doesn’t replace damaged or spalling brick, and it can’t fix structural lean or settlement. If more than 30 percent of the bricks themselves are cracked or deteriorated, or if the chimney has shifted noticeably from vertical, a partial or full rebuild is likely the more cost-effective long-term answer. Our Level-2 camera inspection gives us documentation of the flue interior as well as the exterior courses, so we can give you a straightforward verdict: repoint, partial rebuild, or full rebuild. You’ll see the photos and get a plain-English explanation – then you decide. Call (845) 757-0998 to set up an inspection.
Does repointing require a permit in Hicksville or Nassau County?
Routine mortar repointing on an existing chimney generally does not require a building permit in Nassau County under current residential code, but permit requirements can depend on the scope of work – if the job involves structural repair beyond joint replacement, the threshold may be different. We stay current on local code requirements and will flag anything permit-related before we start work. The last thing a homeowner needs is a code issue surfacing at a home sale years later because a repair wasn’t properly documented.
