We’ve been driving to Willowbrook from our Chicago base for over 42 years. We know the ranch homes along 63rd Street, the split-levels near Harger Road, and the brick colonials tucked behind the Waterfall Glen Forest Preserve. These houses were built during the same construction boom, with the same chimneys, and they’ve aged through the same DuPage County winters. That matters because a technician who understands Willowbrook’s housing stock spots problems faster and fixes them right the first time. Call (888) 289-6055 - a live person answers, 24 hours a day.

Our Chimney Repair Services in Willowbrook
Mortar Repointing
The mortar joints in Willowbrook’s 1960s-1980s brick chimneys have endured 50-plus years of DuPage County’s deep freeze-thaw cycle. Water seeps in, freezes, expands, and grinds the mortar to powder. We grind out the deteriorated joints to proper depth and repack with color-matched, professional-grade mortar formulated for Illinois winters. Done right, repointing adds decades of service life.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic in Willowbrook chimneys that have been saturated and frozen repeatedly. We remove damaged brick, source matching replacements, and rebuild the affected courses with proper bond and weep details. In some cases, spalling has progressed far enough that we recommend partial chimney rebuilding, and we’ll tell you plainly which path makes sense.
Chimney Waterproofing
Willowbrook’s mature trees and shaded lots keep chimney masonry damp longer after rain, accelerating deterioration. We apply breathable, professional-grade waterproofing agents that block liquid water while allowing vapor to escape. This is especially valuable for chimneys on north-facing walls or homes near the Des Plaines River watershed where ambient moisture runs high.
Flashing Repair
The step flashing where chimney meets roof is a common leak point in Willowbrook’s older homes, many of which have seen two or three roof replacements without proper flashing updates. We fabricate and install custom flashing with proper counterflashing integration, sealed with professional-grade compounds. No caulk-only patches that fail in two seasons.
Chimney Rebuilding
When freeze-thaw damage, settling, or decades of deferred maintenance have compromised structural integrity, we rebuild. We’ve reconstructed chimneys from the roofline up on Willowbrook ranches near Kingery Highway and split-levels off Plainfield Road. We match existing brick and mortar color, install proper crowns with adequate overhang and drip edges, and document the work with before-and-after photos.
Tuckpointing
For chimneys where mortar deterioration is early-stage and localized, tuckpointing targets specific joints without full repointing. We use this selectively in Willowbrook, where some chimneys need only targeted intervention while others require more extensive work. Our Level-2 inspection determines which approach is appropriate - no guesswork, no unnecessary demolition.

Trusted Brands We Service in Willowbrook
We stock our Willowbrook service trucks with professional-grade materials from DuraFlex, HeatShield, and Gelco - brands that meet or exceed Illinois building code requirements and perform reliably through our punishing winters. For liner replacements, we specify stainless steel or HeatShield cerfractory flue sealant based on what your chimney needs, not what costs us less. We also source caps, dampers, and crown repair compounds from Olympia Chimney and Famco. Because we carry inventory, most Willowbrook repairs don’t wait on parts. The number on your estimate is the number on your invoice.
Common Chimney Repair Problems We See in Willowbrook Homes
- Original clay flue liners cracked by freeze-thaw cycles. DuPage County’s temperature swings from November through March stress 1960s-70s terra-cotta flue tiles until they fracture. Cracked liners allow combustion gases to leak into wall cavities or living spaces. Our Level-2 camera inspection finds these fractures before they become hazardous.
- Improperly abandoned furnace flues creating cold-air backdrafts. When Willowbrook homeowners upgraded to high-efficiency furnaces, many contractors simply direct-vented the new unit through the sidewall and left the old flue open. That abandoned flue becomes a cold-air column that drafts backward into the house every winter. We cap or line these properly.
- Deteriorated fireboxes with hidden mortar gaps. Fifty years of thermal cycling have loosened firebox mortar in many Willowbrook homes, creating gaps that collect creosote and increase fire risk. Our inspection protocol includes thorough firebox examination with photo documentation.
- Crown failure from inadequate original construction. Many Willowbrook chimneys were built with thin, unreinforced concrete crowns that crack and allow water directly into the chimney core. We rebuild crowns with proper slope, overhang, and reinforcement - or install Gelco pre-formed crowns where appropriate.

FAQs - Chimney Repair in Willowbrook
Your old furnace flue was likely left open when the new high-efficiency unit was direct-vented through the sidewall, creating a cold-air column that drafts backward into your living space. We see this constantly in Willowbrook’s 1960s-70s homes, where the furnace and fireplace originally shared a single chase. We responded to a 1972 split-level on Windmill Drive where the homeowner reported a persistent cold draft from the fireplace. Opening the cleanout revealed a four-inch terra-cotta flue tile that had been abandoned when a 90% furnace was direct-vented; we installed a stainless-steel liner with a top-sealing damper, stopping the backdraft and restoring safe operation. Call (888) 289-6055 - estimates are free.
Warning signs include pieces of terra-cotta tile in the firebox, smoke odors in upstairs rooms, or visible cracks when looking up the flue with a flashlight. The only reliable method is a Level-2 camera inspection, which we document with photos you can see and a plain-English verdict. In Willowbrook’s 50-to-60-year-old chimneys, original clay liners are routinely at or past end of service life. Call (888) 289-6055 to schedule - the inspection itself is the best investment you can make.
Yes, if the crown is cracked but the brick and mortar below are sound. Crown repair typically runs $600-$1,400 in Willowbrook. We remove the damaged crown, pour a new reinforced concrete crown with proper slope and drip edge, or install a Gelco pre-formed crown where appropriate. If spalling brick or deteriorated mortar extends below the crown, partial rebuilding may be more economical long-term. We’ll show you photos and explain both paths. Call (888) 289-6055 for an exact quote.
Stainless steel is the most reliable choice for relining 1970s chimneys in Willowbrook, especially where original clay tiles are cracked or where a furnace flue was abandoned and needs proper conversion. We use DuraFlex or HeatShield materials based on your chimney’s configuration and what appliances it serves. Stainless handles our freeze-thaw cycles and thermal expansion better than aluminum or unlined masonry. Call (888) 289-6055 and we’ll specify the right material for your setup.
Tuckpointing addresses mortar joints only. If bricks are spalling - flaking, crumbling, or losing their faces - the masonry itself is compromised and needs repair or replacement. In Willowbrook’s climate, spalling usually indicates water has been saturating the brick for years. We assess whether localized brick replacement plus repointing will suffice, or whether the damage is extensive enough to warrant partial rebuilding. Our inspection gives you a straight answer with photos. Call (888) 289-6055 - estimates are free.
