Call (888) 289-6055

We’ve been driving to Westmont since 2014, long enough to know the difference between a 1962 ranch on S Williams St and a 1974 bi-level near Ty Warner Park. That matters because the chimney problems those two houses develop are not the same, and showing up with the wrong materials wastes everyone’s time. When you call (888) 289-6055, a live person answers, 24 hours a day. We’ll give you a real arrival window and stick to it.

Our Chimney Repair Services in Westmont

Mortar Repointing

Westmont’s 25-35 annual freeze-thaw cycles grind away at mortar joints faster than in milder climates. On a 1960s ranch near Cass Avenue, we’ve seen original mortar reduced to sand while the brick itself remains solid. Repointing removes the deteriorated material to proper depth and packs new, properly cured mortar that matches the original compressive strength. We color-match to the weathered face of your existing joints, so the repair doesn’t shout from the curb. For a typical Westmont ranch chimney, mortar repointing runs $850-$1,800 depending on access and how many courses need work.

Spalling Brick Repair

Spalling, those flaked and popped brick faces you see on older chimneys, happens when moisture gets in and the freeze-thaw cycle pushes the face off. Westmont’s clay brick from the 1950s-1970s is particularly susceptible because it was fired at lower temperatures than modern brick. We cut out spalled units and replace with matching reclaimed or reproduction brick, then seal the crown and flashings to stop the water source. Left alone, spalling compromises structural integrity and lets water into your walls. A partial brick replacement on a Westmont ranch chimney typically costs $600-$1,400.

Chimney Waterproofing

Westmont’s combination of aging masonry and hard winter rains makes waterproofing one of our most called-for services. We apply vapor-permeable sealers from professional-grade lines like Gelco that let the chimney breathe while blocking liquid water. This is critical on 60559’s ranch homes, where the chimney often sits dead center on a low roof with minimal overhang protection. Waterproofing a standard Westmont chimney runs $400-$900 and extends the life of your mortar and brick by years. We recommend it after any repointing or spalling repair, not as a standalone cosmetic treatment.

Flashing Repair

The step flashing where your chimney meets the roof is the most common leak point we find in Westmont’s older housing stock. Many of these homes were built with galvanized steel flashing that has corroded through after sixty years, or with improper counter-flashing that lets wind-driven rain run behind. We fabricate and install custom copper or lead-coated copper flashing, soldered at seams, with proper reglets cut into the mortar joints. For Westmont’s low-slope ranch roofs, this is exacting work that can’t be rushed. Typical flashing repair or replacement runs $750-$1,600.

Trusted Brands We Service in Westmont

Our trucks carry professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney, the brands we specify because they hold up to Chicago’s freeze-thaw abuse. For Westmont’s aging clay-tile flues, we stock DuraFlex stainless steel liner kits in multiple diameters, which lets us replace a deteriorated liner in one trip rather than ordering parts and making you wait. HeatShield’s cerfractory resurfacing system handles minor liner cracks without full replacement, a square deal for homeowners whose liners are borderline. We don’t use builder-grade substitutes. The materials matter as much as the labor, and we choose both with the expectation that our work will outlast the next three owners of your house.

Common Chimney Repair Problems We See in Westmont Homes

• Cracked clay-tile liners from freeze-thaw cycling. Westmont’s 25-35 freeze-thaw cycles per winter attack clay tile from the inside when condensation meets cold flue gases. Cracks open pathways for carbon monoxide and creosote migration, especially dangerous in double-flue chimneys serving both furnace and fireplace.
• Spalling brick and mortar deterioration on ranch homes. Decades of moisture cycling through porous clay brick pop faces off and grind joints to powder. The damage accelerates once the protective crown or cap fails, which is why we inspect both as part of any repair call.
• Misidentified steel prefab inserts in masonry surrounds. In Westmont’s 1960s ranch neighborhoods, original steel prefab fireplace inserts hide inside masonry facings. Homeowners assume they have a masonry fireplace needing standard liner inspection, when the unit actually requires manufacturer-specific clearances and may be unsafe after decades of minimal service.
• Failed chimney crowns and inadequate overhang protection. Westmont’s center-chimney ranch design leaves the crown exposed to full sun, rain, and freeze-thaw with no roof overhang for shelter. Concrete crowns crack, steel crowns rust, and water enters the flue system year-round.

In the Hickory Hills neighborhood off N Cass Ave, we replaced a deteriorated clay-tile liner that was cross-contaminated from a double-flue chimney serving both a wood fireplace and a gas furnace. Using a heavy-duty DuraFlex stainless steel liner, we completed the job in one trip, as Westmont homeowners expect.
