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 Easton, PA
Mortar repointing is the process of removing deteriorated mortar from the joints between chimney masonry and packing fresh, correctly mixed mortar in its place. In Easton, PA, most brick chimneys built before the 1990s need repointing at some point – the original mortar simply wears out, and when it does, water finds its way in. A repointing job done with the right mortar mix and proper technique will hold for twenty to thirty years. Done wrong, or skipped entirely, the damage spreads from the joints into the brick itself, and at that point you’re looking at a much larger repair.
At Hearthstone Chimney Co., repointing is one of the most common repairs we handle across Easton and the surrounding Lehigh Valley. Russell Haines has been overseeing this work since we opened in 1984, and the standard here hasn’t changed: right mortar mix, proper joint depth, clean finish, documented with photos you can actually see. If you’ve noticed crumbling or missing mortar on your chimney, call us at (610) 756-1504 – we answer live, every hour of every day.
Repointing is part of our broader Chimney Repair in Easton service, and it’s one of the better investments a homeowner can make in an older masonry chimney. Catch the joints early, and the brick behind them stays intact. Wait, and you’re paying for far more than mortar.
When You Need Mortar Repointing
Mortar doesn’t fail all at once. It softens gradually, pulls back from the brick, and eventually crumbles out. Here are the signs we look for – and that you can spot yourself from the ground or at the roofline:
- Visible gaps or recessed joints. If the mortar between your bricks sits noticeably below the face of the brick – sometimes a quarter inch or more – it’s no longer shedding water. It’s collecting it. This is the clearest sign that repointing is overdue.
- Crumbling or sandy mortar. Sound mortar is hard. If you can scrape material out of a joint with your fingernail or a key, the mortar has lost its binding strength. In Easton’s climate, freeze-thaw cycles from November through March accelerate this process faster than many homeowners expect.
- White staining (efflorescence) on the brick face. White mineral deposits on the surface of your chimney brick are a reliable signal that water is moving through the masonry. Failed mortar joints are one of the most common entry points.
- Water stains or dampness inside the firebox. If the back wall of your fireplace shows water marks after heavy rain, deteriorated mortar joints are a likely culprit – especially on the chimney sections exposed above the roofline on older homes in the West Ward and Forks Township areas, where chimneys take the full brunt of northwest wind and driving rain.
- Spalling brick faces. When water gets behind failing mortar and freezes, it can pop the face right off a brick. If you’re finding brick fragments in your gutters or on the roof in spring, the joints likely failed first.
- A chimney that hasn’t been inspected in more than five years. Most repointing problems are invisible from street level until they’re well advanced. A Level-2 camera inspection often catches failing joints two or three years before they become visible to the naked eye.
Our Mortar Repointing Process
Repointing a chimney properly takes more time and care than it might look from the street. The single biggest mistake we see from other contractors – and from homeowners who attempt it themselves – is applying new mortar over old mortar without cutting out the failed joint first. That approach fails within a season. Here’s how we do it:
- Full inspection before any work begins. We photograph the chimney from ground level and from the roof. On jobs where interior joint condition is unclear, we use our Level-2 camera to document the flue liner as well. You’ll see the photos. You’ll hear a plain-English explanation of what’s there. No guessing, no surprises.
- Joint removal to proper depth. Failed mortar gets ground or chiseled out to a minimum depth of three-quarters of an inch – enough for the new mortar to develop a real mechanical bond. We do not score the surface and skim over it. The work takes longer this way, but it’s the only method that holds.
- Mortar mix selection matched to your brick. This step matters more than most homeowners realize. The replacement mortar must be softer than the surrounding brick. If the mortar is too hard – a common error with off-the-shelf Type S mixes applied to older Easton brick – the brick itself becomes the sacrificial layer and you get spalling. We assess the age and hardness of your masonry and mix accordingly.
- Packing and tooling the joints. Fresh mortar is packed in layers and tooled to match the original joint profile. The finish isn’t just cosmetic – the profile determines how well the joint sheds water. A proper concave or “rodded” joint will outlast a flat or poorly finished one by years.
- Post-work inspection and documentation. Once the mortar has cured enough to photograph clearly, we document the completed work and walk you through what was done. If anything doesn’t look right to either of us, it gets addressed before we leave.
- 90-Day Done Right Promise. Every repointing job we complete is covered in writing. If anything fails or wasn’t done correctly, we come back and make it right – no arguing, no paperwork fight, no charge. That’s the standing commitment.
Mortar Repointing Pricing in Easton
Mortar repointing in Easton, PA typically runs between $400 and $2,500 for residential chimneys, depending on the scope of the work, and you can learn more in our How Much Does Chimney Repair Cost? (2026 Price Guide) - Easton, PA. Here’s how that range breaks down in practice:
- Spot repointing (localized joint failure, 1-3 areas): $400 – $750. Common on chimneys where the cap or crown kept the main shaft in decent shape but two or three courses near the top have deteriorated.
- Full repointing of the exposed chimney stack above the roofline: $800 – $1,500. This is the most frequent scope on Easton-area homes built between 1930 and 1975, where the chimney stands three to five feet above the ridge and the full exposed section needs attention.
- Full chimney repointing including sections below the roofline or on a tall two-story stack: $1,500 – $2,500. Taller chimneys require additional staging or lift equipment, which adds to the labor cost.
Several factors move the price within those ranges:
- Chimney height and roof pitch. A steep roof on a Victorian-era home in the College Hill neighborhood adds setup time and safety equipment requirements. A single-story rancher in Palmer Township with a low-pitch roof and a short stack is faster to access.
- Extent of joint failure. A chimney where only the top two courses need attention costs much less than one where the entire exposed face has recessed joints throughout.
- Whether spalled brick also needs addressing. If individual bricks have begun to face-spall due to long-term water infiltration through failed joints, those bricks need to be replaced before repointing proceeds. That adds material and labor.
- Mortar color matching. If you want the repointed joints to closely match aged original mortar – common on historically significant homes along the Delaware River corridor – custom mortar tinting takes additional time and materials.
We provide upfront pricing before any work starts. The number on the estimate is the number on the invoice – there are no add-ons discovered partway through the job. And if your repair comes to more than $250, our standing $50 Off Any Repair Over $250 offer applies. We also offer a 5% discount for seniors and veterans, permanently, on every job.

Why Mortar Composition Matters in Easton’s Climate
Easton sits at the confluence of the Lehigh and Delaware Rivers, which means the chimneys here face a particular combination of humidity, freeze-thaw cycling, and driving rain from multiple directions. The ridge-top and hillside homes between Easton proper and Phillipsburg see some of the highest exposure in the region – northwest wind in January can push water directly into failing joints and freeze it overnight.
This climate reality is why mortar type is not a one-size-fits-all decision. Pre-1950 Easton chimneys were often built with a lime-based mortar that is softer and more flexible than modern Portland cement mixes. When a contractor fills those old joints with a high-Portland modern mix, the mortar grips too rigidly, and thermal expansion in summer or contraction in a hard freeze cracks the brick rather than the joint. We see the results of that mistake regularly – on chimneys in the South Side, on the older two-flue stacks in the Northampton Heights area, and on restored rowhouses near Scott Park.
Getting the mix right is a technical judgment, not a guess. It’s part of what forty-two years of doing this work in this region teaches you.
What Sets Hearthstone Apart on Repointing Work
There are contractors who will pack fresh mortar over old mortar, collect a check, and leave. You won’t know the joint failed until the following spring. Here’s what we do differently:
- Photos before and after, every time. You see the condition of the joints before we start and the finished work when we’re done. If you weren’t home during the job, we bring the documentation to you.
- Professional-grade materials. We work with trusted brands in the chimney trade – including Copperfield and HeatShield products where applicable – not whatever is on the shelf at a big-box store that morning.
- Single-visit completion on most jobs. We don’t schedule the inspection for one day and the work for three weeks later unless the scope genuinely requires it. Most repointing jobs in Easton are assessed, quoted, and completed in a single visit or two closely scheduled ones.
- Background-checked, uniformed technicians. The person on your roof is vetted, identifiable, and accountable. That’s a baseline standard we’ve held since 1984.
- The 90-Day Done Right Promise in writing. If the work isn’t right, we come back. No fee, no argument, no process to navigate. That’s what backing your work looks like.
This is also why we’ve been a going concern in Easton and the Lehigh Valley for over forty-two years. A company that plans to be in this area for another forty years does the job right the first time. Russell Haines built Hearthstone on that premise in 1984, and it’s still the way things work here.

FAQs – Mortar Repointing
How much does mortar repointing cost in Easton, PA?
Mortar repointing in Easton typically costs between $400 and $2,500, depending on how much of the chimney needs attention, the height of the stack, and whether any brick replacement is also needed. Spot repairs on a standard single-story chimney tend to run $400 to $750. A full repoint of the exposed stack above the roofline on a mid-century home generally falls in the $800 to $1,500 range. We’ll give you an upfront price before any work begins, and we honor that number on the invoice. Call (610) 756-1504 for a free estimate.
How long does repointed mortar last?
Properly done repointing, with mortar matched to the hardness of the existing brick and applied at the right joint depth, lasts twenty to thirty years in Easton’s climate. The key variables are mortar selection, joint preparation depth, and whether the chimney crown and cap are keeping bulk water out. Repointing that uses a mix that’s too hard for the surrounding brick, or mortar applied over uncleaned failed joints, may fail in as little as two to four winters. That’s not a hypothetical – it’s something we’re called to fix regularly.
Can I repoint my chimney myself?
The short answer is that basic repointing on accessible, low areas is something some experienced DIYers tackle, but chimney repointing carries real risks that make professional work the safer choice for most homeowners. Working at height on a roof is inherently dangerous, and the consequences of a fall are serious. Beyond the physical hazard, selecting the wrong mortar type – too hard a mix for older Easton brick – can cause spalling damage that costs more to fix than a proper repoint would have. If you’re considering a DIY approach, we’re happy to give you a free second opinion on whether the scope is realistic for a homeowner to handle safely, or whether it warrants a professional. Call us at (610) 756-1504.
How do I know if my chimney needs repointing or full rebuilding?
Repointing is the right answer when the brick itself is structurally sound and only the mortar joints have deteriorated. Rebuilding becomes necessary when the brick faces have Spalling Brick Repair damage significantly, when sections of the chimney have shifted or leaned, or when the damage extends through the full depth of the masonry. The line between the two isn’t always visible from the ground. Our Level-2 camera inspection documents the condition of the full chimney, gives you photos you can see, and produces a plain-English verdict on whether you’re looking at a repointing job or something more. There’s no charge for the estimate. Call (610) 756-1504 to schedule.
