When a Mount Greenwood homeowner calls, we’re usually there within the same day or next.

Our Chimney Cap & Crown Services in Mount Greenwood

Crown Repair

Crown repair is the most common call we get from Mount Greenwood bungalows. The original mortar crowns installed in the 1920s and 1930s were never designed to survive a century of Chicago freeze-thaw cycles. We see advanced spalling - surface flaking and joint separation - on nearly every uncoated crown over 80 years old.

Our process starts with a Level II camera inspection to assess what’s happening beneath the surface. For crowns with intact structural integrity but surface deterioration, we clean, patch, and apply a professional-grade coating. For crowns that have cracked through to the flue tile, partial or full rebuild is the only sound option. Either way, you get photos, a plain-English verdict, and a written estimate before any work begins.

Custom Cap Installation

Mount Greenwood’s bungalow chimneys come in dimensions that don’t always match big-box inventory. Flue sizes vary. Some chimneys have offset flues from retrofitted gas conversions. Others need extended heights to clear nearby rooflines on the neighborhood’s characteristic one-and-a-half-story profiles.

We measure, fabricate, and install custom caps in galvanized steel, stainless steel, or copper. Copper caps cost more upfront - typically $650-$1,400 installed versus $280-$580 for stainless - but they develop a protective patina and outlast the house on a well-maintained crown. For homeowners who plan to stay, copper is often the last cap they’ll ever buy.

Multi-Flue Cap Installation

Most Mount Greenwood bungalows have a single chimney chase serving two flues: one for the furnace, one for the fireplace. These shared crowns crack unevenly because the furnace flue runs hot and dry while the fireplace flue experiences intense temperature spikes and moisture from combustion.

A multi-flue cap covers both flues with a single protective shelter while maintaining proper separation. This prevents cross-drafting, keeps debris and animals out of both flues, and eliminates the weak point where two separate caps meet at the crown’s center. We size and install multi-flue caps from Gelco and Olympia Chimney to fit your exact chase dimensions.

Crown Coating & Waterproofing

For crowns with minor cracking but solid structure, a professional coating extends service life by 10-15 years. We use HeatShield and DuraFlex crown coating products - not the hardware-store brush-on sealers that trap moisture and accelerate damage. Our coating process includes surface preparation, crack filling, and a breathable, flexible top layer that moves with the masonry through freeze-thaw cycles.

This is often the right choice for Mount Greenwood homeowners whose crowns show early-stage deterioration but haven’t yet failed structurally. Caught at annual inspection, a coating job is roughly one-third the cost of rebuild.

Trusted Brands We Service in Mount Greenwood

We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that meet the specifications Chicago’s climate demands, not builder-grade substitutes that fail in year three. For Mount Greenwood customers, this means faster turnaround and no waiting on special orders. Our trucks carry the common bungalow flue sizes, cap dimensions, and coating materials needed to complete most jobs in that single visit. When we recommend a product, it’s because we’ve watched it perform on 111th Street chimneys through twenty Chicago winters.

Common Chimney Cap & Crown Problems We See in Mount Greenwood Homes

• Original mortar crowns spall after 80+ years of freeze-thaw exposure. Mount Greenwood’s position on the far southwest side, away from Lake Michigan’s moderating effect, means temperature swings hit harder. Water penetrates micro-cracks, freezes, expands, and flakes off surface mortar. By the time you see staining on the ceiling near the chimney, water has been entering for seasons.
• Undersized or absent liners in legacy coal flues cause crown seal failure. When these chimneys were converted to gas, the lower exhaust temperatures produced acidic condensate that attacks mortar from the inside. The crown deteriorates faster than the exterior brick because it’s being eaten from both directions.
• Shared crowns on multi-flue chimneys crack unevenly. One flue expands with furnace cycling; the other sits cold until fireplace season. The thermal differential stresses the crown’s centerline, creating a crack that channels water directly into the chase between flues.
• Suburban contractors unfamiliar with Chicago permit requirements. Because Mount Greenwood is within Chicago city limits, not an adjacent suburb, all chimney cap and crown work falls under City of Chicago permit and inspection requirements. We’ve corrected jobs where out-of-area companies skipped permits, leaving homeowners with code violations and no recourse when problems emerged.
