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 Evanston, IL
Mortar repointing in Evanston typically costs between $400 and $1,800 depending on how many linear feet of joint need to be cut out and packed, and most jobs can be completed in a single visit. If you’re seeing crumbling white lines between your chimney bricks, a repoint done now will cost a fraction of what a partial rebuild costs two winters from now. Call us at (708) 234-1174 and we’ll put a written price in your hands before anyone touches your chimney.
Evanston chimneys take a particular kind of beating. The city sits directly on Lake Michigan, and the freeze-thaw cycles here are more punishing than they are even ten miles west. Water works into hairline mortar joints in October, freezes and expands in January, and by spring those joints are wider than they were the fall before. We see this progression constantly in older brick construction throughout the Dempster Street corridor, in the Lakeshore Historic District, and in the pre-war two-flats that run up Central Street toward the border with Wilmette. The brick in most of these homes is genuinely good material – original Chicago common brick or Purington pavers – but the mortar is sacrificial by design. It’s supposed to wear out before the brick does. Repointing at the right time preserves that masonry for decades more. Ignoring it lets water reach the brick face itself, leading to Spalling Brick Repair needs brick is a much more expensive conversation.
Level Two Chimney Evanston has been working on these structures since 2009, more than 38,000 chimney inspections and repairs completed under the Haven Standard, every one of them with a written price before the work started and a documented photo record when it was done. Mortar repointing falls under our Chimney Repair in Evanston service, and it follows the same process: a camera-scan inspection first, a written scope second, work only after you’ve approved the price in writing.
When You Need Mortar Repointing
A few things to look for before you call – any one of these is enough to warrant an inspection:
- Mortar joints recessed more than a quarter inch. Run your finger along the horizontal joints between courses. If the mortar sits noticeably behind the brick face and crumbles under light pressure, the bond has failed and water now has a direct channel into the chimney stack. In Evanston’s climate, this moves fast once it starts.
- White staining (efflorescence) on the chimney exterior. That white powdery residue is mineral salt carried out by water moving through the masonry. It means water is already inside the stack – repointing stops the entry point; ignoring it usually leads to a spalling brick face within two to three seasons.
- Mortar powder or small chunks at the base of the chimney or on the flashing. If you’re finding debris on your roof or in your gutters near the chimney, the upper joints – the most exposed section – are actively shedding. Upper courses in Evanston properties lose mortar faster than lower ones because the wind off the lake is carrying moisture horizontally, not just vertically.
- Gaps visible at the chimney crown or where the stack meets the flashing. This is a related but distinct problem: the crown and flashing seal the top and base of the stack, but if the joints midway up are failing simultaneously, the whole system is compromised. We’ll note all of it in the inspection report so the scope is complete.
- A chimney that hasn’t been inspected since you bought the house. If you purchased between 2015 and 2025 and the seller’s disclosure said “fireplace in as-is condition,” there’s a reasonable chance the mortar joints haven’t been touched in fifteen or twenty years. We see this regularly in the properties near Dawes Park and in the blocks east of Ridge Avenue – brick structures that look solid from the street but have significant joint erosion at the upper two feet of the stack.
- Water staining on the firebox interior or a damp smell from the fireplace. By the time moisture is showing inside the firebox, it has already moved through the liner and stack. That path usually runs through failed mortar joints somewhere above the roofline. A Level 2 camera inspection will show us exactly where.
Our Mortar Repointing Process
Here’s exactly what happens when you schedule a repointing job with us. Nothing is skipped to save time, and nothing is added to inflate the scope.
- Camera-scan inspection before any work is priced. We run a camera down the flue under NFPA 211 Level 2 protocol and photograph the full exterior of the stack. This tells us whether the liner is intact, whether the crown has failed independently, and which joint sections are actually compromised. We are not pricing a job blind. The inspection produces a written report with photos – you get a copy.
- Written scope and price, delivered before the tech is on your roof. Under Haven Standard Clause 1, you receive a written price, a written scope of work, and a written warranty before anyone picks up a grinder. The price on that document is the price on your invoice. If the inspection finds additional damage that wasn’t visible from the ground, we show you the photo, explain what it means, and get written approval for any change in scope. This is non-negotiable on every job we run.
- Mechanical removal of failed mortar to a minimum depth of three-quarters of an inch. We use angle grinders and hand chisels to cut out the deteriorated material. Three-quarters of an inch is the minimum depth required for a mechanically sound bond between the new mortar and the brick – a shallower cut produces a repoint that fails within a few seasons. In Evanston’s freeze-thaw environment, we typically cut to a full inch on exposed upper courses.
- Joint preparation and mortar mix selection. This step matters more than most homeowners realize. The replacement mortar has to be softer than the brick – specifically, it needs to have a lower compressive strength than the masonry units it sits between. Using modern Type S or Type N mortar on pre-1950s Chicago common brick is correct practice. Using Type M mortar on original soft brick causes the brick face to spall because the harder mortar can’t flex with the brick. We match the mortar type to the masonry, not to what’s cheapest or fastest. Where color matching to original mortar is a priority – particularly in the Lakeshore Historic District where the city may have preservation standards – we discuss that in writing as part of the scope.
- Packing and tooling the new joints. New mortar is packed in layers into the prepared joints, then tooled to match the original profile – typically a struck or rodded joint on Evanston residential stacks. Tooling compresses the surface, which reduces porosity and improves weather resistance. We don’t rush the cure; in colder weather we use appropriate admixtures and staging to ensure the mortar sets correctly.
- Post-work photo documentation and delivery of the completed record. When the job is done, we photograph every section of repointed work and add it to your documented file under Haven Standard Clause 4. You leave with a physical and digital record of what was done, where, and what materials were used. If you sell the house, that record goes with the disclosure. If you have a warranty claim, the photos are already there.

AfterMortar Repointing Pricing in Evanston
Mortar repointing in Evanston runs between $400 and $1,800 for most residential chimney stacks. The range is wide because the variables are real: stack height, number of accessible sides, how deeply the mortar has deteriorated, and whether the crown needs attention at the same time. Below is a breakdown of what typically drives the number.
| Job Type | Typical Range (Evanston Market) |
|---|---|
| Spot repointing – upper two courses, one side | $400 – $600 |
| Full upper-stack repointing – all four sides above roofline | $650 – $950 |
| Full stack repointing – above and below roofline | $950 – $1,400 |
| Tall stacks or difficult access (steep pitch, third-story chimney) | $1,200 – $1,800 |
| Repointing combined with crown repair or cap replacement | Quoted as a bundled written scope |
What affects your number specifically:
- Linear footage of joint. More brick courses above the roofline means more joint to cut and pack. A single-story ranch near South Boulevard has a short exposed stack. A three-story Victorian in the Lakeshore district might have six feet of exposed chimney above the ridge.
- Roof pitch and scaffold requirements. Some Evanston homes – particularly the steeper-pitched houses near the Gross Point Road area – require additional setup time for safe access. That’s reflected in the written quote, not added as a surprise afterward.
- Mortar depth required. If the joints have eroded two inches back, there’s more material to cut out and more mortar to pack in. The inspection tells us this before we price it.
- Historic district considerations. If your property falls under Evanston’s Lakeshore Historic District guidelines, mortar color matching and specific joint profiles may be required. We’ve done this work before and know what the city expects; it adds modest time but not a dramatic cost premium.

FAQs – Mortar Repointing
How long does mortar repointing last on an Evanston chimney?
Done correctly with the right mortar type, a repoint should last 20 to 30 years on a residential chimney in Evanston. The key variables are mortar selection, joint depth, and whether the crown and cap are keeping water off the top of the stack. If the mortar is matched to the brick’s compressive strength and the joints are cut to at least three-quarters of an inch before packing, the bond holds through the freeze-thaw cycles this climate produces. Repoints that fail in five years are almost always a product of insufficient cut depth or a mortar mix that was too hard for the original brick. Call (708) 234-1174 to get a written scope that includes mortar specifications – so you know exactly what’s going in.
Can I repoint my chimney myself?
The basic motion of packing mortar into a joint is not dangerous, but getting the mortar mix wrong on a pre-1950s Evanston chimney is a significant and costly mistake. Using a mortar that’s harder than the original brick will cause the brick faces to pop and spall as the stack expands and contracts – and How Much Does Chimney Repair Cost? (2026 Price Guide) - Evanston, IL will show you that spalling brick work is substantially more expensive than the repointing job you were trying to save money on. Working at roofline height also carries real risk, particularly on steeper-pitched homes. If you want to look at the joints and tell us what you’re seeing, we’re happy to take a look and give you a written assessment. But the cutting, mixing, and packing we’d recommend leaving to a tech who does this daily.
Is repointing different from tuckpointing?
Repointing and tuckpointing are often used interchangeably, but technically tuckpointing is a specific finish technique where a narrow contrasting-color strip is tooled into the center of a wider joint to create the visual impression of fine, precise brickwork. What most homeowners need – and what we quote – is repointing: removing deteriorated mortar and replacing it with a fresh, properly matched compound. If you’ve received a “tuckpointing” estimate from another company and want to know exactly what they’re proposing, bring us the written estimate and we’ll break down what’s in scope. The Free Second Opinion is always available.
Does mortar repointing fix water coming into my fireplace?
Repointing addresses one of the most common water entry paths – failed mortar joints on the chimney stack – but it’s not always the only source. A Level 2 camera inspection will show us whether the liner is cracked, whether the crown has failed, and whether the flashing at the roofline is seated correctly. In Evanston, we see situations where the mortar joints and the crown are failing simultaneously, particularly on stacks that haven’t been serviced in fifteen or more years. We’ll document everything in the inspection report and give you a written scope that covers the actual source of the problem, not just the most visible symptom. Call (708) 234-1174 – the inspection and written price come before any work starts.
Key Takeaways
- Mortar repointing in Evanston runs $400 to $1,800 depending on stack height, joint depth, and access conditions – written price in hand before work begins, always.
- Evanston’s Lake Michigan exposure accelerates mortar erosion on the windward face of chimney stacks; properties in the Lakeshore Historic District and older brick two-flats along Central Street are particularly susceptible.
- Every repointing job starts with a camera-scan inspection under NFPA 211 Level 2 protocol – so the price reflects what’s actually there, not what’s visible from the ground.
- Mortar type has to match the original brick. On pre-1950s Chicago common brick, the wrong mortar causes spalling within a few seasons.
- The 365-Day Done Right Promise covers every repointing job. If it’s not right, we make it right.
- A Free Second Opinion on any written estimate from another company is always available – bring us the document.
