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.

AfterSpalling Brick Repair in Downers Grove, IL
Spalling brick repair in Downers Grove typically costs between $350 and $1,800, depending on how many courses of brick are affected and whether the mortar joints need Mortar Repointing alongside the brick replacement. Most jobs on a standard chimney are completed in a single visit. If you’re seeing chunks of brick on the ground near your chimney or flaking brick faces on the stack above the roofline, that’s spalling – and it doesn’t stop on its own.
Spalling is what happens when water gets into the porous face of a brick, freezes, expands, and breaks the surface apart from the inside. Downers Grove winters give that cycle plenty of chances to run. A brick that survives a Chicago-area January thaw intact can still lose its face by March after six or seven freeze-thaw cycles work through it. Once the outer face of a brick pops off, the exposed interior absorbs water even faster, and the damage spreads to adjacent courses.
At Emberly Chimney Cleaners Downers Grove, we’ve seen this pattern on houses throughout town – from the older Victorians near Main Street to mid-century brick colonials in Fairmount and the post-war ranches off Ogden Avenue – and we handle it through our Chimney Repair services. The fix is the same principle everywhere: remove the compromised brick or repoint the deteriorated mortar, match the replacement material as closely as possible to what’s there, and seal the assembly correctly so the next freeze cycle doesn’t restart the process. Before any work begins, you get a written price, a written scope, and a written warranty – that’s Haven Standard Clause 1. No surprises after the truck is in the driveway.

When You Need Spalling Brick Repair
Not every chimney problem announces itself with a crack you can see from the street. Spalling can start quietly and show up in ways homeowners in Downers Grove don’t immediately connect to the chimney. Here’s what to watch for:
- Brick faces or chips on the ground near the chimney base. This is the clearest sign. If you’re finding reddish or orange fragments on the roof, in the gutters, or on the patio below the stack, the brick surface is actively breaking apart. In Downers Grove, this tends to show up most obviously in late March and April, after the last hard freeze has done its work.
- Visibly pitted, flaking, or hollow-looking brick on the chimney stack. Stand back and look at the chimney from the yard. Bricks that look pocked, cratered, or like the outer layer has simply sloughed off are already spalling. A flashlight inspection from a ladder will confirm it – or our camera-scan inspection will document every affected course with photos.
- White powdery staining on the chimney face. This is efflorescence – mineral salts that water carries out of the brick as it migrates through the masonry. It’s not structural damage by itself, but it tells you water is moving through the brick, and spalling is usually close behind if the source isn’t addressed.
- Crumbling or recessed mortar joints alongside brick damage. Spalling and mortar joint deterioration often travel together. When the mortar between courses breaks down, it lets more water into the brick, which accelerates the freeze-thaw damage. If you’re seeing both at once, the repair scope will typically include repointing as well as brick replacement.
- Water staining on the interior ceiling or wall near the fireplace. Interior water damage doesn’t always mean a liner or crown problem. If the exterior brick is spalling badly enough, water can work its way through the chimney assembly and show up inside. Downers Grove homes with older chimneys and no drip cap or weather-seal at the crown are particularly prone to this.
- A chimney inspection report flagging masonry deterioration. If a Level 2 NFPA 211 inspection – camera down the flue, documented photo record – has already flagged exterior masonry as deteriorating, spalling repair belongs on the work list before the next heating season. Ignoring it gives the damage a full summer of moisture infiltration before winter starts the freeze cycle again.
Our Spalling Brick Repair Process
We follow the same documented process on every job. You’ll know what step we’re on and why, and you’ll have photos when we’re done.
- Camera-scan inspection and written assessment. Every spalling brick repair visit starts with a full NFPA 211 Level 2 inspection. We put the camera down the flue, photograph the exterior masonry from the base to the crown, and document exactly which courses are affected and how far the damage has progressed. You get the photos. This isn’t an extra – it’s how we work, and it’s been the standard at Emberly since 2009. The inspection also tells us whether the problem is isolated spalling, widespread mortar failure, a deteriorated crown letting water in from the top, or some combination. That matters for pricing the right scope.
- Written price, scope, and warranty before any work starts. Once the inspection is done, we give you a written price for the specific repair – number of bricks, courses affected, whether repointing is needed, materials specified. You sign off on it. No work starts until you have that document in hand. This is Haven Standard Clause 1, and it’s not optional on any job we do in Downers Grove or anywhere else.
- Removal of damaged brick and deteriorated mortar. A background-checked, uniformed technician removes only what’s actually compromised. We don’t pull sound brick to pad a job. Spalled brick and crumbling mortar are removed carefully to avoid disturbing the courses above, and the cavity is cleaned out so the replacement material bonds correctly. For mortar joint work, we cut to a consistent depth – typically 3/4 inch to 1 inch – before repointing.
- Matching and setting replacement brick. Brick match matters, especially on older Downers Grove chimneys where the original units may be a different size or color than modern stock. We source replacement brick through Haven’s buying network – including suppliers like Copperfield and Gelco – and we’ll be upfront with you if a close match is the best we can do versus an exact one. New brick is set in Type S mortar, which is the appropriate mix for exterior chimney work in this climate: strong enough to hold, flexible enough to move with the freeze-thaw cycle without cracking out.
- Repointing mortar joints where needed. If the inspection identified deteriorated mortar joints beyond just the spalled section, we repoint those courses in the same visit. Fresh mortar is tooled to match the existing profile – concave, raked, or flush – so the repair doesn’t stand out visually and so water sheds correctly rather than pooling in the joint.
- Sealing and documented photo record on completion. Once the masonry work is done and cured, we apply a penetrating masonry sealer appropriate for the brick type. This slows water infiltration without trapping moisture inside the brick – a common mistake with the wrong sealers that makes spalling worse over time. We photograph every repaired section before we leave. That documented photo record goes on file under Haven Standard Clause 4. If anything comes back on us, you have proof of the condition we left it in.
BeforeAfterSpalling Brick Repair Pricing in Downers Grove
Spalling brick repair in Downers Grove runs from about $350 on the low end for a small, accessible section of a few bricks up to $1,800 or more for an extensive repair that covers multiple courses or requires significant repointing alongside brick replacement. See How Much Does Chimney Repair Cost? (2026 Price Guide) - Downers Grove, IL for a detailed breakdown. The variables that move the number most are the count of damaged bricks, how high on the chimney the damage sits, whether the mortar joints need attention too, and how accessible the work area is from the roof.
| Repair Scope | Typical Price Range |
|---|---|
| Minor spalling – up to 5 bricks, accessible location | $350 – $550 |
| Moderate spalling – 6 to 15 bricks, some repointing | $550 – $1,000 |
| Significant spalling – 16+ bricks or multiple courses | $1,000 – $1,800 |
| Repointing only (mortar joints, no brick replacement) | $300 – $750 |
| Masonry sealer application (standalone or add-on) | $150 – $300 |
A few things worth understanding about these ranges. First, the inspection always comes before the price. We don’t quote spalling repair over the phone because we genuinely don’t know the scope until we’ve seen the photos and camera footage. What looks like a few damaged bricks from the yard can be ten courses of compromised mortar once we’re up there. Second, the written price you receive after the inspection is the price – not an estimate that grows once the work is underway. Third, if you already have a written quote from another contractor, bring it to us. We offer a free second opinion on any written estimate, no obligation.
Materials for spalling repair sourced through Haven’s buying network – including Copperfield and Gelco masonry products – are procured specifically to keep customer prices honest. We’re not marking up materials bought at retail and passing that cost along.

What Downers Grove’s Climate Does to Chimney Brick
This isn’t boilerplate weather copy – the freeze-thaw cycle in DuPage County is genuinely harder on chimney masonry than in milder climates, and it’s worth understanding why if you’re weighing whether to repair now or wait.
Downers Grove sits in USDA Hardiness Zone 5b, which means average winter lows in the -10 to -15 Fahrenheit range are possible, and the shoulder seasons – October through December and February through April – regularly deliver multiple freeze-thaw cycles in a single week. Each cycle pushes water that has absorbed into porous brick through a small expansion. One cycle does very little. Fifty cycles over two winters can pop the face off a brick that looked fine at a glance. The chimneys most at risk are the ones without an intact crown at the top to shed water away from the stack, no cap to keep rain out of the flue, and original brick that has never been sealed. That description fits a significant portion of the older housing stock in neighborhoods like Belmont and Lyman Woods near the east side of town.
The repair strategy has to account for this climate. Type S mortar is specified for this reason – it’s rated for severe freeze-thaw exposure. Sealers that are vapor-permeable allow the brick to dry out between wet cycles rather than trapping moisture inside. These aren’t upsell decisions; they’re the correct material choices for this zip code.
Spalling vs. Other Chimney Masonry Problems
Spalling is sometimes confused with other masonry issues that look similar from the ground. It’s worth being clear on the differences, because the repair is different.
Spalling is the mechanical failure of the brick face itself – the outer layer breaks free due to internal freeze-thaw pressure. The brick body is still in place; the surface has fractured and separated.
Mortar joint deterioration is a separate problem. The mortar between bricks erodes over time, especially where it wasn’t mixed correctly or wasn’t rated for exterior exposure. Repointing addresses this; it doesn’t fix spalled brick.
Efflorescence is the white mineral staining that appears when water migrates through masonry. It’s cosmetic evidence of a moisture problem, not structural damage by itself. Cleaning it away without addressing the water source accomplishes nothing lasting.
Chimney crown cracking is a different problem at the top of the chimney stack – the poured concrete or mortar cap that covers the top of the chimney around the flue. A cracked or missing crown lets water straight down into the flue and across the top courses of brick. Repairing the crown is part of stopping the water source; it doesn’t replace the brick repair itself. This falls under our broader home inspection and repair framework.
In Downers Grove, we regularly see all four of these showing up on the same chimney simultaneously, especially on homes built between 1950 and 1980 where the original masonry has had 45 to 75 years of weather exposure with no major maintenance. The inspection scopes out all of it, and the written price covers exactly what’s needed – nothing more.

FAQs – Spalling Brick Repair
How much does spalling brick repair cost in Downers Grove?
Spalling brick repair in Downers Grove costs between $350 and $1,800 for most residential chimneys. The exact number depends on how many bricks are affected, how high on the chimney the damage is, and whether mortar joint repointing is needed at the same time. After our camera-scan inspection documents the full scope, you get a written price before anyone picks up a trowel. Call (331) 253-4980 to schedule – the estimate is free.
Can spalling brick be repaired, or does the whole chimney need to be rebuilt?
Spalling brick can almost always be repaired rather than requiring a full rebuild, as long as the underlying chimney structure is sound. A rebuild becomes necessary when the damage has progressed through the full thickness of a large section of the chimney, or when the interior structure – liner, smoke chamber – has failed independently. The camera-scan inspection tells us which situation we’re in. Most of the spalling jobs we see in Downers Grove are discrete repairs, not full rebuilds. Call (331) 253-4980 and we’ll document exactly what’s there.
How long does spalling brick repair take?
Most spalling brick repairs on a residential chimney in Downers Grove are completed in a single day. The inspection, repair, and sealing typically run three to five hours depending on scope. You do need to stay off the fireplace for at least 24 hours after new mortar is set – we’ll be specific about the cure window in your written scope. Larger jobs spanning multiple courses may carry over to a second day, and that schedule is confirmed before work starts.
What happens if I don’t repair spalling bricks on my chimney?
Unrepaired spalling accelerates. Once the face of a brick has popped off, the exposed interior absorbs water faster than the intact outer surface did, which means the freeze-thaw damage runs deeper and spreads to adjacent bricks each season. In Downers Grove’s climate, a chimney that has minor spalling in the spring can have significant structural deterioration by the following spring if nothing is done. Water that penetrates deeply enough can also reach the smoke chamber and liner, turning a masonry surface repair into a much larger interior repair. The cost of waiting is almost always higher than the cost of fixing it now. If you have a written estimate from another contractor, bring it to us for a free second opinion before you decide.
