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 Bangor, PA
Mortar repointing is the process of removing deteriorated mortar from the joints between chimney masonry and packing in fresh, properly mixed mortar to restore a weathertight bond. In Bangor, most chimneys built before the 1990s used a hard Portland cement mix that eventually becomes brittle under repeated freeze-thaw cycles – and once the joints start crumbling, water gets in, bricks shift, and repair costs climb fast. Done at the right time, repointing is one of the most cost-effective our Chimney Repair services a homeowner can invest in.
Hearthstone Chimney Co. has been doing this work in the Bangor area since 1984 – over 42 years of pointing joints, reading mortar failures, and watching our repairs hold up through Northampton County winters. Russell Haines and our crew treat every chimney the way a mason would: prep work first, right mortar mix for the brick, clean joints, and a finished surface that sheds water instead of collecting it. If you are seeing gaps, white staining, or spalled brick around your chimney, call us at (610) 609-7634 – a live person will pick up, every hour of every day.

Why Mortar Joints Fail Faster in Bangor Than You Might Expect
Bangor sits at roughly 1,100 feet in elevation along the Blue Mountain ridge, and that matters for masonry. The town sees more freeze-thaw cycles per winter than lower-elevation communities in the Lehigh Valley – sometimes 30 to 40 distinct freeze-thaw events between November and March. Every time water soaks into a mortar joint and freezes, it expands roughly 9 percent. Do that 35 times a year for 20 years and even a well-laid chimney starts to look hollow between the courses.
Older homes in Bangor’s West Ward and along Broadway were typically built with lime-based mortar, which is actually more flexible than modern cement mixes and sometimes holds up better over time. But somewhere in the mid-20th century, contractors switched to stiffer Portland cement mortars. That harder mix is actually weaker than the historic brick it surrounds, so when movement occurs, the brick cracks instead of the joint. Fixing that kind of mismatched mortar requires removing the stiff material and replacing it with a formulation that matches the original brick’s compressive strength – not just whatever bag is on the shelf at the supply house.
We see the same pattern in Pen Argyl and Wind Gap: homeowners who had a quick patch done by a handyman two or three years ago are now calling us because the patch material is already flaking away. The chemistry has to be right, not just the color.
When You Need Mortar Repointing
- Mortar joints that are recessed more than a quarter inch. When you can fit a fingernail into the joint, water already has a channel into the chimney. At a quarter inch or deeper, repointing is overdue – not optional.
- Visible crumbling or powder when you press the joint. Soft or sandy mortar means the bond has broken down. The material looks solid from a distance but offers no real weather protection. This is common on the north-facing side of chimneys in Bangor, where the sun never fully dries the masonry between rains.
- White staining (efflorescence) on the chimney face. That white powdery residue is dissolved mineral salts being carried out of the masonry by water moving through the joints. It is a reliable sign that water is traveling through the mortar rather than shedding off it.
- Spalled or flaking brick faces. When the mortar joints fail, water migrates into the brick itself. In a Bangor winter, that trapped water freezes and pops the face off the brick. Repointing early stops the cycle before you need full brick replacement.
- Damp spots on the interior ceiling or firebox wall. Water that enters through deteriorated joints can travel several feet before it becomes visible inside. If you are seeing staining on the ceiling near the chimney or on the back wall of the firebox, the joints are a likely entry point.
- A chimney that was last repointed more than 20 years ago. Even mortar that looks intact from the ground can be failing at depth. A Level-2 camera inspection often reveals joint deterioration that is not visible from a ladder.
Our Mortar Repointing Process
- Photo inspection and assessment before a tool comes out. Russell Haines or one of our background-checked technicians walks the job first – checking joint depth with a probe, noting mortar color and hardness, looking for past patch attempts that used the wrong mix, and photographing everything. You see the same photos we see, and we give you a plain-English explanation of what we found before any work starts. No surprises on the bill starts here.
- Matching the mortar to the masonry. This step separates a lasting repair from one that fails in two winters. We determine the approximate mix specification for the original mortar – whether it is a lime-heavy Type N or a stiffer Type S – and match the new material accordingly. Using a harder mix than the brick can accommodate causes the brick faces to crack and spall. We use professional-grade materials, including products from Gelco and Olympia Chimney supply lines, because the quality of the mortar material is not a place to cut costs.
- Joint preparation and removal of old mortar. We cut or grind the deteriorated mortar to a minimum depth of three-quarters of an inch – typically one inch on joints that are already recessed or visibly crumbled. Skipping this step and pointing over shallow old mortar is the reason so many patch jobs fail. A thin topping coat has nothing to bond to and cracks off in the first freeze cycle.
- Cleaning and wetting the joints. Before new mortar goes in, we clean the joint of dust and debris and lightly dampen the brick edges. If dry brick pulls moisture out of the fresh mortar too quickly, the mortar does not cure properly and the bond is weak from day one. Small detail, big difference.
- Packing and tooling the new mortar. We pack mortar in layers on deeper joints rather than trying to fill depth in a single pass. Once the mortar reaches the proper stage of firmness, we tool the joint surface to match the surrounding profile – typically a concave or weather-struck finish that directs water away from the face of the chimney. Color matching is done by eye and sample on the first joint before we commit to the rest of the chimney.
- Final walk-around, cleanup, and written documentation. When the work is done, we photograph the finished joints and leave you a written record of what was done. Every job is covered by our 90-Day Done Right Promise: if anything is not right, we come back and make it right, in writing, no arguing. That is not marketing language – it is how we have operated for over 42 years.
Mortar Repointing Pricing in Bangor
Repointing costs in Bangor vary based on how much of the chimney needs work, how accessible it is, and how deep the joint deterioration runs. A chimney that only needs the crown-adjacent courses touched up costs considerably less than one where three or four full sides need to be cut and packed. Below are honest ranges based on what we see in this market.
| Scope of Work | Typical Range (Bangor Market) |
|---|---|
| Spot repointing – isolated sections, 10 to 20 joints | $180 – $320 |
| Partial repointing – one or two sides of the chimney stack | $350 – $650 |
| Full chimney repointing – all four sides, above roofline | $650 – $1,200 |
| Full repointing with Level-2 inspection included | $750 – $1,400 |
A few things that affect where your job lands in those ranges: roof pitch and chimney height add to the time required to work safely. A chimney on a steep-pitched roof above a three-story wall in one of Bangor’s older Victorian homes takes longer to reach than one on a flat-roof addition. The number of previous patch attempts also matters – heavy old topping coats take longer to remove cleanly. And if we find brick damage during the inspection that goes beyond mortar, we will tell you before we start, not after.
We offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans. Estimates are free, and the number on the estimate is the number on the invoice – upfront pricing, no add-ons at the door. Call (610) 609-7634 and we will schedule a time that works for you.
What Sets Hearthstone Apart on a Repointing Job
A lot of contractors will point a chimney. Fewer will do the prep work correctly, match the mortar properly, and still be in business when you call two years later with a question. Hearthstone Chimney Co. has been in Bangor and the surrounding area since 1984. We plan to be here in thirty more years. That changes how we approach every job – because our reputation is the only thing that keeps this company running, and a repointing failure is easy to see on a sunny day from the sidewalk.
Russell Haines oversees every job and the crew who does the work. Our technicians are background-checked, uniformed, and trained on the mortar specifications that matter for historic masonry in older Pennsylvania towns. We document with photos, explain in plain English, and back the result in writing. That is the 90-Day Done Right Promise – not a feel-good tagline, but an actual commitment: if it is not right, we come back and make it right, no paperwork, no arguing.
We are also part of the broader work we do through our home base of services – chimney cleaning, liner installation, crown repair, and full rebuilds – so if an inspection reveals that your chimney needs more than repointing, you will hear about it plainly and get an honest picture of what the full repair involves and what it can wait on.
FAQs – Mortar Repointing in Bangor
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 are deteriorated. A full rebuild is needed when bricks are cracked through, when sections of the chimney have shifted out of plumb, or when structural damage runs deeper than the joints alone. The honest answer is that you cannot always tell from the ground – which is why we include photos and a plain-English assessment with every inspection. Call us at (610) 609-7634 and we will give you a straight answer at no charge.
How long does mortar repointing last?
Repointing done with the correct mortar mix and proper joint preparation typically lasts 20 to 30 years in a climate like Bangor’s – sometimes longer on sheltered sections of the chimney that see fewer freeze-thaw cycles. Work done with mismatched mortar or without adequate joint preparation can fail in as little as two to four winters, which is the most common reason homeowners call us after getting a cheap repair elsewhere. The mix matters as much as the labor.
Can I repoint the chimney myself?
The physical motion of applying mortar is not complicated, but getting the mortar mix right for your specific brick, preparing the joints to the correct depth, and working at chimney height safely – those are the parts that go wrong when repointing is attempted without experience. A mismatched mortar mix can cause the surrounding brick to crack and Spalling Brick Repair needs, turning a $400 repair into a $2,000 problem. If the chimney is accessible from a low section of roof and the scope is very limited, a careful homeowner can manage a small spot repair. Anything above the roofline or involving more than a few courses, call a professional. The height risk alone warrants it.
Does repointing fix a leaky chimney?
Deteriorated mortar joints are one of the three most common chimney leak sources – along with a failed crown and a missing or damaged cap. Repointing will seal the water entry points at the joints, but if your chimney is also missing a cap or has a cracked crown, those problems need to be addressed at the same time or the leaking will continue through a different path. Our inspection documents all the leak sources so you know exactly what is contributing to the problem and can make a clear decision about what to repair now and what to schedule later.
