We’ve worked on chimneys in Des Plaines for over 42 years, from the postwar ranches near Algonquin Road to the split-levels off Golf Road and the Cape Cods closer to the Des Plaines River. We know the ZIP codes here - 60016, 60017, 60018, 60019 - and we know what the local housing stock demands. Most Des Plaines chimneys were built between 1950 and 1975. They’re aging out. The question isn’t whether they’ll need work. It’s whether the work gets done before water, vibration, or freeze-thaw damage turns a repair into a rebuild.

Our Chimney Repair Services in Des Plaines
Mortar Repointing
Repointing is the process of grinding out deteriorated mortar between bricks and packing new mortar into the joints. In Des Plaines, this is often the first major repair a chimney needs, and it comes earlier than it should. The constant low-frequency vibration from O’Hare jet traffic - Des Plaines sits directly under some of the busiest flight paths in the world - loosens mortar joints faster than in quieter suburbs like Park Ridge or Niles. We’ve repointed chimneys in Des Plaines that were only thirty years old but showed the mortar fatigue we’d expect to see at fifty.
We use Type N mortar mix, which balances strength and breathability for the Chicago-area freeze-thaw cycle. The job ends with a clean joint profile and our 90-Day Done Right Promise in writing.
Spalling Brick Repair
Spalling - when brick faces flake, pop, or crumble - happens when moisture gets inside the brick and freezes. Des Plaines has a double problem: the severe freeze-thaw cycle, plus ground moisture from the Des Plaines River corridor that wicks into chimney bases and exploits any micro-cracks in aging mortar. Jet vibration from O’Hare accelerates the whole process by loosening the mortar that would otherwise keep water out.
We replace spalled bricks with matching units, repoint surrounding joints, and seal the crown to stop the cycle. Done right - and we stand behind it.
Chimney Waterproofing
Waterproofing a Des Plaines chimney requires more than a spray-on sealant from a hardware store. We apply vapor-permeable treatments that let the masonry breathe while blocking liquid water, critical in a climate where chimneys go from soaked to frozen in a single day. We pay special attention to the chimney base in Des Plaines homes, where river-corridor moisture and splashback from downspouts create chronic wetting. Our waterproofing jobs include crown sealing, flashing inspection, and a written condition report with photos.
Flashing Repair
The metal flashing where your chimney meets the roof is the most common leak point we find in Des Plaines inspections. On the postwar ranches and split-levels that dominate this city, the original flashing was often step-flashing with a basic counterflange, installed quickly during the 1960s building boom. After fifty-plus winters, the sealant has failed, the metal has fatigued, or the vibration from O’Hare traffic has worked the fasteners loose. We remove the old flashing, inspect the decking, and install new professional-grade flashing with proper integration into the roofing system.

Common Chimney Repair Problems We See in Des Plaines Homes
- Jet vibration from O’Hare loosens mortar joints prematurely. Des Plaines chimneys endure constant low-frequency vibration that quieter suburbs don’t experience. A chimney that might last decades in Mount Prospect can show accelerated spalling and loose joints here, making annual inspection more critical than in neighboring communities not under heavy flight paths.
- Abandoned furnace flues cause chronic downdraft and creosote buildup. Many 1960s-70s Des Plaines homes had combination chimneys serving both a gas furnace and a fireplace. After high-efficiency furnace retrofits, the abandoned flue leaves the chimney oversized for fireplace-only use. We find this pattern repeatedly in east-side neighborhoods off Oakton and Rand Roads, where homeowners report smoke backing up into the living room and heavy creosote condensation in the flue.
- Freeze-thaw plus river-corridor moisture widens micro-cracks at the chimney base. The Des Plaines River corridor adds localized ground moisture that wicks into foundation-level masonry. Combined with sub-zero temperatures followed by rapid thaws, this exploits any weakness in aging mortar at an accelerated rate compared to drier Midwest climates.
- Aging postwar chimneys reach end of original service life without major tuckpointing. The bulk of Des Plaines housing stock was built between 1950 and 1975. Most masonry chimneys in the city are now 50-75 years old. The original mortar has simply aged out, and the bricks are beginning to show it.

FAQs - Chimney Repair in Des Plaines
Constant low-frequency vibration from jet aircraft loosens the bond between mortar and brick, accelerating joint deterioration beyond normal aging. In Des Plaines, we regularly see chimneys with mortar fatigue that would take decades longer to develop in quieter suburbs. The vibration works like a slow-motion jackhammer, especially on chimneys already stressed by the freeze-thaw cycle. Annual inspection is more critical here than in neighboring communities not under heavy flight paths. Call (888) 289-6055 to schedule - estimates are free.
Have a Level-2 camera inspection performed to assess liner condition, creosote buildup, and draft performance. We find this situation repeatedly in east-side Des Plaines neighborhoods off Oakton and Rand Roads, where high-efficiency furnace retrofits left combination chimneys oversized for fireplace-only use. The abandoned flue causes chronic downdraft, heavy creosote condensation, and accelerated liner deterioration. Depending on what the camera shows, we may recommend a new properly sized liner, a smoke chamber modification, or in some cases partial rebuilding. Call (888) 289-6055 - we’ll document everything with photos and a plain-English verdict.
Three forces converge here that don’t converge elsewhere: O’Hare jet vibration, severe freeze-thaw cycles, and ground moisture from the Des Plaines River corridor. Together they exploit chimney weaknesses faster than in drier or quieter suburbs. A small mortar crack that might take five years to become a leak in Niles can become a leak in two years in Des Plaines. Early repair prevents rebuild-level costs. Call (888) 289-6055 for an inspection - the 90-Day Done Right Promise applies to every job.
Type N mortar is the right choice for most Des Plaines chimneys - it provides sufficient compressive strength for above-grade work while remaining breathable enough to let moisture escape, critical in our freeze-thaw climate. We never use Type S on historic or aging masonry; it’s too strong and can cause the brick to spall instead of the mortar yielding. We repointed a 1960s ranch chimney in the east-side neighborhood off Oakton Road where years of jet vibration had loosened nearly every mortar joint. After grinding out the old mortar, we applied new Type N mix and sealed the crown to prevent moisture from the nearby Des Plaines River corridor from exploiting any remaining micro-cracks. Call (888) 289-6055 if your mortar is crumbling - we’ll match the mix to your chimney’s age and condition.
Yes. These are common in Des Plaines’s 1960s-70s housing stock, and we’ve repaired dozens across the city. The key issue is that the abandoned furnace flue leaves the chimney oversized, causing poor draft, smoke backup, and accelerated creosote condensation. Our approach depends on what the Level-2 camera inspection reveals: sometimes a new properly sized liner solves it, sometimes the smoke chamber needs reshaping with HeatShield, and sometimes structural repair is needed first. We document everything with photos and explain your options in plain English before any work begins. Call (888) 289-6055 - most combination chimney repairs are completed in a single visit.
