We’ve been driving to Chicago Heights from our Chicago base for over 42 years.

Our Chimney Repair Services in Chicago Heights
Tuckpointing & Mortar Repointing
Tuckpointing in Chicago Heights demands more than matching color. The lime-mortar joints in these 1910s-1930s chimneys have endured 50-70 years of coal soot, then acidic gas condensation, then deep freeze-thaw cycling. We see chimneys near the older worker-housing blocks that were tuck-pointed once in the 1970s and never touched again. The pointing looks passable from the ground. Behind it, the mortar is powder. We grind out the failed joint to proper depth and repoint with professional-grade mortar formulated for Chicago Heights’s thermal stress. A typical mortar repointing job on a Chicago Heights bungalow runs $680-$1,400.
Chimney Rebuilding
When differential settling on sandy glacial-lake soils has shifted the chimney breast beyond what spot repair can correct, partial or full rebuilding becomes necessary. We’ve rebuilt chimneys on Chicago Heights two-flats where the original structure had tilted three inches off plumb, threatening the roof-wall junction. We salvage sound brick where possible, rebuild with matching masonry, and install a proper liner system sized for modern gas appliances. Rebuilding a Chicago Heights chimney typically costs $1,800-$2,800 depending on height and access.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - accelerates on north-facing chimneys in Chicago Heights’s older blocks. Freeze-thaw cycling drives moisture deeper each winter. Once the brick face pops off, the inner structure absorbs water faster. We remove spalled units, match replacement brick for color and hardness, and address the moisture source. Often that’s failed crown mortar or deteriorated flashing at the roof line. Spalling brick repair in Chicago Heights generally runs $450-$950.
Chimney Waterproofing
Chicago Heights’s combination of driving lake-effect precipitation and hard winter freeze-thaw makes waterproofing essential, not optional. We apply vapor-permeable sealers that let the masonry breathe while blocking liquid water. This is critical on chimneys with original lime mortar that needs to exhale moisture. Waterproofing a standard Chicago Heights chimney costs $380-$650 and protects the investment you’ve made in repointing or rebuilding.
Flashing Repair
Flat-roof two-flats in Chicago Heights, common near the downtown core, suffer flashing failure at the roof-wall junction where the chimney breast meets the parapet. Water migrates behind the chimney, freezes, and expands cracks through the masonry. We fabricate and install custom flashing with proper step and counterflashing integration, sealed for thermal movement. Flashing repair on a Chicago Heights two-flat typically runs $520-$890.

Trusted Brands We Service in Chicago Heights
We stock professional-grade materials from HeatShield, DuraFlex, and Olympia Chimney for Chicago Heights jobs, which means faster turnaround and no waiting on special orders. HeatShield’s cast-in-place liner system is particularly valuable here: when we find offset flue tiles from decades of soil settling, we can seal the displaced sections without a full liner replacement. DuraFlex provides the flexible stainless liners we need for tight clearances in bungalows with minimal chimney chase space. Olympia Chimney’s components meet the spec for coal-conversion flue resizing. We don’t use builder-grade substitutes. The material has to last as long as our promise.
Common Chimney Repair Problems We See in Chicago Heights Homes
- Hollow tuckpointing from 1970s repairs fails under freeze-thaw cycling. The mortar looks intact from the ground but has no bond to the brick behind. Moisture traps inside, then expands through Chicago Heights’s hard winters, spalling bricks on north-facing exposures in the older worker-housing blocks near 14th Street and the historic core.
- Oversized flues from coal-to-gas conversion remain unlined, allowing acidic condensation. When Chicago Heights homes converted to natural gas in the 1950s-1970s, the flue passages were never resized. Cooler exhaust condenses on clay tile, depositing acidic moisture that dissolves lime mortar joints and causes internal collapse invisible from the ground.
- Flashing deteriorates at roof-wall junctions on flat-roof two-flats. Water enters behind the chimney breast, freezes, and expands cracks through the masonry. We see this pattern repeatedly on the alley-access two-flats where parking constraints make ladder placement challenging - our techs are equipped for rear-entry setup.
- Differential settling on sandy glacial-lake soils shifts flue tile joints out of alignment. This offset accelerates liner deterioration and creates gaps where flue gases infiltrate the brickwork. Repair approaches must compensate for uneven settling, not just patch the visible damage.

FAQs - Chimney Repair in Chicago Heights
Most likely, yes. The oversized flue passage designed for coal exhaust allows modern gas exhaust to cool too quickly, causing acidic condensation that destroys clay tile and mortar from the inside. We inspect with a camera to confirm the condition. If the tiles are intact but the flue is oversized, we may recommend a properly sized stainless liner or a HeatShield cast-in-place system. Call (888) 289-6055 for a free inspection - estimates are free.
Because we’ve found hollow tuckpointing on dozens of Chicago Heights chimneys that appeared sound from below. Mortar applied in the 1970s often failed to bond properly and has been sitting as a shell while moisture penetrates behind it. Our camera inspection and probe testing reveal the truth. In writing, no arguing - if we find it’s sound, we’ll tell you that too. Call (888) 289-6055 for an honest assessment.
Yes, and we’ve done so many times in Chicago Heights. We first determine whether the lean is stable or progressive. If stable, we may rebuild with compensating courses and install a flexible liner system that accommodates minor movement. If progressive, we address the foundation issue before rebuilding. Either way, we document the condition with photos and explain your options plainly. Call (888) 289-6055 to schedule an evaluation.
Yes. Our technicians are equipped for rear-entry setup on Chicago Heights’s alley-load properties. We’ve worked on dozens of two-flats where street parking is restricted and front access is impractical. We coordinate with you on gate access and protect your alley surface during the job. Most repairs still complete in a single visit. Call (888) 289-6055 to arrange access.
It shouldn’t. A proper vapor-permeable waterproofing application lasts 5-10 years on Chicago Heights masonry. If someone told you annual reapplication is necessary, you may have received a lower-grade treatment or a sales pitch. We use professional-grade sealers that breathe with the masonry while blocking liquid water. Chicago Heights’s lake-effect precipitation and freeze-thaw cycling demand this level of protection, but not annual reapplication. Call (888) 289-6055 if you’d like us to evaluate your current treatment.
