We’ve been working on Wilmette chimneys for over 42 years, since 2014. We know the village’s housing stock - the substantial brick and masonry homes built from 1910 to 1950, many with multiple fireplaces, original clay flue tiles, and tall decorative chimneys designed to match the scale of Tudor and Colonial Revival architecture. These chimneys weren’t built for the modern heating loads they now carry, and they face conditions their original masons never anticipated.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is the most visible chimney problem we see in Wilmette, and it almost always starts on the lake-facing side. East of Sheridan Road, wind-driven moisture from Lake Michigan saturates the masonry, then winter freeze-thaw cycles pop the brick faces off. We recently repointed a 1928 Tudor Revival chimney on a home just off Sheridan Road near Gillson Park. The lake-facing side had spalled bricks and a cracked clay tile liner due to decades of freeze-thaw cycling. We used DuraFlex stainless steel liner and galvanized flashing to match the original aesthetics while providing corrosion resistance. Spalling brick repair in Wilmette typically runs $800-$1,800 depending on how many courses need replacement and whether the underlying liner is compromised.

Chimney Waterproofing

Waterproofing a Wilmette chimney requires more than a generic sealer from a hardware store. The product must be vapor-permeable - it needs to let trapped moisture escape while blocking new water entry. We use professional-grade formulations from HeatShield and Copperfield, applied after any mortar repointing or brick replacement is complete. For lakefront homes near Gillson Park or along Michigan Avenue, we often recommend two coats with extra attention to the crown wash and the interface between brick and flashing. Chimney waterproofing in Wilmette typically costs $450-$950 for a standard single-flue chimney, with larger multi-flue structures running higher.

Flashing Repair

The metal flashing where your chimney penetrates the roofline is a common failure point in Wilmette, especially on east-facing flues. Lake winds create negative pressure that pulls rainwater and melting snow into gaps that might stay dry in calmer locations. We fabricate and install custom flashing using galvanized steel or copper, sealed with professional-grade compounds from Gelco. Flashing repair in Wilmette generally runs $400-$850 for standard replacement, with complex rooflines or steep pitches toward the higher end.

Mortar Repointing

The mortar joints in Wilmette’s century-old chimneys were originally mixed with lime and sand formulations that are softer than modern Portland cement. That’s actually good - the mortar was meant to sacrifice itself so the bricks wouldn’t crack. But after 80 to 110 years of Lake Michigan’s wet freeze-thaw cycles, that mortar has often eroded to a depth of an inch or more. We grind out the failed joints to a proper depth and repoint with color-matched, historically appropriate mortar that complements the original masonry. Mortar repointing in Wilmette typically costs $1,200-$2,400 for a standard chimney, with very tall or multi-flue structures running toward $3,500.

Trusted Brands We Service in Wilmette

We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Wilmette’s older homes, we stock stainless steel liners, crown repair compounds, and flashing materials sized for the larger flue dimensions common in pre-1950 construction. This means faster turnaround and fewer return trips. When we specify DuraFlex liner for a Wilmette chimney, it’s because that product’s corrosion resistance matches what lakefront moisture demands.

Common Chimney Repair Problems We See in Wilmette Homes

• Lake-side face spalling before interior damage appears. Chimneys on homes along and near Sheridan Road frequently show exterior spalling even when the homeowner reports no draft issues. The lake-side face deteriorates first and fastest. We inspect that windward face before climbing, because what looks cosmetic from the ground often signals crown or liner failure beneath.
• Cracked clay tile liners in tall, decorative chimneys. Wilmette’s Tudor and Colonial Revival chimneys were built tall and substantial for architectural effect. That extra height means extra thermal stress and more surface area exposed to wind and moisture. The original clay flue tiles crack from repeated expansion and contraction, especially in chimneys venting modern high-efficiency appliances that never get hot enough to fully dry the masonry.
• Failed crowns and flashings on east-facing flues. Lake winds hitting the east side of Wilmette homes create negative-pressure downdrafts that drive moisture into crown cracks and flashing gaps. The crown - the concrete or mortar cap at the chimney top - cracks from thermal stress, then lake wind does the rest.
• Multi-flue chimneys with mixed venting. Many Wilmette homes have chimneys carrying one flue for a fireplace and another for an older gas furnace or water heater. The gas appliance’s moist exhaust cools quickly in the tall flue, accelerating liner deterioration while the fireplace flue suffers from disuse and moisture intrusion.
