Why Hearthstone Chimney Co. of Chicago Is Elmhurst’s Preferred Chimney Repair Company
We’ve worked on chimneys along York Street, in the neighborhoods near Wilder Park, and throughout the residential blocks off Prospect Avenue for more than four decades. Elmhurst homeowners tend to stay put, and they remember which contractors showed up on time and which ones disappeared. Our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back. That matters when you’re 65, you’ve lived in the same house for thirty years, and you don’t want to chase anyone down.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. Background-checked, uniformed technicians arrive when we say they will, and most repairs are finished in one visit. The number on your estimate is the number on your invoice. We’ve built our reputation in DuPage County on that square deal.
Elmhurst’s mature elm canopy and pre-war dual-flue chimneys create repair scenarios we see nowhere else in the western suburbs. A technician who doesn’t know to check that second, idle flue - the one capped off when the furnace converted to gas - misses half the problem. We don’t miss it.
Our Chimney Repair Services in Elmhurst
Chimney Waterproofing
Elmhurst’s 30-40 annual freeze-thaw cycles turn porous brick into a sponge. Water enters in October, freezes by December, and spalls the face off your clay tiles by March. Our waterproofing uses professional-grade vapor-permeable sealers from HeatShield and Copperfield - they block liquid water but let the chimney breathe and dry. We never seal without first addressing existing saturation; trapping moisture behind a barrier destroys vintage masonry faster than leaving it alone. For homes near the Salt Creek watershed or in low-lying sections of 60126 where groundwater pressure runs higher, we often recommend crown sealing as part of the waterproofing package.

Tuckpointing and Mortar Repointing
The lime-based mortar in Elmhurst’s pre-war chimneys was never meant to last a century. It erodes, it crumbles, and once the joints are open, water has a direct path to the flue. Our tuckpointing matches the original mortar composition - softer than modern Portland cement, so the brick bears stress instead of the joint. In the Bryn Mawr Manor neighborhood off Prospect Avenue, we repaired a 1928 Tudor Revival with two linked stuccoed chimneys; the idle furnace flue had been left open and, over years, deposited elm seeds and soot inside the active fireplace flue. Our crew relined both flues with DuraFlex, sealed the unused flue with a stainless-steel cap, and tuckpointed eroded mortar joints to prevent collapse. Repointing without first sealing porous brick is a mistake we see other crews make - moisture trapped behind new mortar spalls the face of vintage clay tiles within one winter.

Flashing Repair
Step flashing where the chimney meets the roofline is the most common leak point we find in Elmhurst’s older homes. The original galvanized steel flashing from the 1930s and 1940s corrodes, and the sealant behind it dries to dust. We fabricate custom flashing on-site to match your roof pitch and chimney profile, using Gelco components where specified. Homes in the hills near Elmhurst College see more wind-driven rain, which tests flashing harder than flatter sections of town. We inspect the cricket, the counterflashing, and the saddle - not just the visible front edge.

Spalling Brick Repair
When freeze-thaw damage has already popped the face off your brick, cosmetic tuckpointing won’t save the structure. We remove and replace spalled units with matching reclaimed or reproduction brick, then repoint the surrounding joints. For chimneys where spalling is widespread - common on south- and west-facing exposures in Elmhurst that absorb maximum thermal cycling - we assess whether partial rebuilding makes more sense than piecemeal repair. We’ll tell you straight.

Common Chimney Repair Problems We See in Elmhurst Homes
- Idled second flues acting as moisture conduits. Many pre-war Elmhurst homes were built with a two-flue chimney stack - one serving the fireplace, one serving a coal or oil furnace. When gas conversions retired the furnace flue, that second flue was often simply capped or left open and forgotten. Decades later it is a hidden liability: uncleaned, unmaintained, accumulating debris, and wicking water into the shared masonry that also protects the active fireplace flue.
- Standard caps failing against elm debris. Elmhurst - long nicknamed the ‘City of Elms’ - maintains one of DuPage County’s densest mature tree canopies even after Dutch elm disease. Overhanging branches deposit leaves, twigs, and seed debris directly into flues, making chimney cap integrity a recurring issue unique to this suburb. Using standard caps on oversized pre-war flues allows elm seeds and leaves to bypass the screen and accumulate in the flue.
- Oversized flues from fuel conversions condensing and spalling. The city’s primary growth era (1920s-1940s) produced a large concentration of original clay-tile-lined masonry chimneys that were later retrofitted for gas appliances, leaving oversized flues prone to condensation, liner spalling, and moisture intrusion.
- Spring efflorescence revealing winter damage. The Chicago western-suburb climate delivers 30-40 freeze-thaw cycles in a typical winter, which steadily crack clay tile liners and erode mortar crowns on Elmhurst’s aging brick stacks. Spring inspections following harsh winters are especially productive here because moisture that penetrated porous brick all season becomes visible as efflorescence and spalled tile fragments once the chimney dries.

FAQs - Chimney Repair in Elmhurst
Yes, and it’s one of the most overlooked hazards in Elmhurst’s pre-war housing stock. That idle flue was never designed to sit unmaintained; the cap may have failed, the liner may be cracked, and debris accumulation can channel water into the shared masonry wall that also protects your active fireplace flue. We inspect both flues with our camera system and provide photos of each. Call (888) 289-6055 to schedule - estimates are free.
You need a cap with a properly sized mesh screen and a lid profile that sheds debris rather than collecting it. Standard hardware-store caps often have mesh too coarse to stop elm seeds or lids too flat to shed leaf buildup. We fabricate and install stainless steel caps sized to your specific flue opening, with 5/8-inch mesh that blocks seeds while maintaining draft. Call (888) 289-6055 and we’ll measure your flue on the first visit.
Every 25-40 years for chimneys in Elmhurst’s climate, though harsh winters with heavy freeze-thaw cycling can accelerate erosion. If you can fit a knife blade into mortar joints, or if you notice sand washing out after rain, the repointing window is open. We inspect mortar condition as part of every Level-2 inspection and will show you the photos. Call (888) 289-6055 to book.
It affects everything. Coal flues are oversized for modern gas appliances, which means lower exhaust temperatures and condensation that pools on the flue walls, accelerating liner deterioration. Relining with a correctly sized DuraFlex stainless steel liner is often the right repair, not just repointing the outside. We size liners to the appliance, not the existing flue. Call (888) 289-6055 for an inspection that includes flue sizing analysis.
Waterproofing alone won’t fix spalling - the damaged brick needs replacement or resurfacing first. However, once repairs are complete, vapor-permeable waterproofing is essential protection for Elmhurst’s porous vintage brick. We use HeatShield sealers that block liquid water entry while allowing trapped moisture to escape. Never apply waterproofing over active leaks or saturated brick; we test moisture content before sealing. Call (888) 289-6055 and we’ll assess whether your chimney is ready.
