We’ve been working on Lynwood chimneys since the early 1980s, back when oil-to-gas conversions were just getting started across Cook County’s south suburbs. Our Chimney Cap & Crown team knows the 1950s-1970s brick ranches along Glenwood-Dyer Road and the split-levels near the Indiana border. These aren’t generic houses with generic problems. They’re aging masonry chimneys with original clay flue tiles, precast concrete crowns that have taken fifty winters of freeze-thaw, and caps that were often added as afterthoughts during furnace conversions. That local knowledge matters. It means we show up with the right parts, the right materials, and no need for a second trip.

Our Chimney Cap & Crown Services in Lynwood
Custom Cap Fabrication & Installation
Standard caps don’t fit Lynwood’s aging dual-use flues. After oil-to-gas conversions in the 1980s and 1990s, many local chimneys were left with oversized flues that run cool and accumulate condensation. An off-the-shelf cap gaps, leaks, and accelerates liner deterioration. We measure on site and fabricate custom caps from heavy-gauge copper and stainless steel, sized precisely for your flue dimensions. On a job in the Lincoln Hills neighborhood, we replaced a rusted-through flat cap on a 1960s brick ranch that had been dumping rainwater directly onto the clay flue tiles. We custom-fitted a heavy-gauge multi-flue copper cap from Copperfield, seating it with a mortar crown to seal the gap between clay tile and brick - one trip, done right.
Multi-Flue Cap Installation
Many Lynwood ranches have two or more flues sharing a single chimney chase - one for the Lynwood Fireplace Services we provide, one for the furnace. Multi-flue caps cover the entire crown, eliminating the gaps between individual caps where water and animals enter. We size and install Gelco and Olympia Chimney multi-flue systems with integrated mesh screening, built to withstand the wind exposure that comes with Lynwood’s open south-suburban terrain. Done right - and we stand behind it.
Crown Repair & Reconstruction
The precast concrete crowns on original 1950s chimneys crack after decades of freeze-thaw cycling. Lynwood’s location, where Lake Michigan moisture meets aggressive temperature swings, makes this worse than in drier inland communities. Water seeps through crown cracks, saturates clay flue joints, and causes spalling brick that requires full Chimney Repair in Lynwood. We repair minor crown damage with professional-grade crown coating and rebuild severely deteriorated crowns with poured concrete, sloped for drainage and reinforced to last. Photos you can see, a plain-English verdict on whether repair or rebuild is the smarter spend.
Crown Coating & Waterproofing
For crowns with surface cracking but sound structural integrity, we apply flexible crown coating formulated for Chicago’s climate. This isn’t hardware-store sealant. We use HeatShield and professional-grade compounds that expand and contract with temperature swings without delaminating. A proper coating adds years of service to a Lynwood chimney crown, delaying the cost of full replacement. We’ll be there when we say, and we’ll tell you honestly whether coating is sufficient or if you’re throwing good money after bad.

Trusted Brands We Service in Lynwood
We stock parts and materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney on our service trucks, which means most Lynwood repairs don’t wait on shipping. When we custom-fabricate a cap for a 1960s ranch with an oversize flue, we’re measuring, cutting, and installing in one visit - not ordering and returning. No builder-grade substitutes. The brands we use are the same ones specified by chimney professionals nationwide because they survive what Chicago winters throw at them. That matters in Lynwood, where lake-effect moisture and repeated freeze-thaw cycles test every seal and joint.
Common Chimney Cap & Crown Problems We See in Lynwood Homes
- Precast concrete crowns cracking from freeze-thaw damage. Original 1950s chimneys across Lynwood were topped with precast concrete that wasn’t designed for fifty-plus years of temperature swings. Water enters hairline cracks, freezes, expands, and widens the damage until the crown fails completely. We see this on ranch homes from Torrence Avenue west to the state line.
- Undersized sheet-metal caps from 1990s furnace conversions. When oil furnaces became gas, many installers added cheap caps that don’t cover the full flue opening. Moisture enters the gap, condenses in the cool oversized flue, and accelerates liner deterioration behind the cap. Homeowners often mistake the white efflorescence for a cleaning issue.
- Missing caps on detached workshop chimneys. Lynwood’s self-reliant homeowners sometimes skip caps on outbuilding chimneys. Without protection, birds nest, leaves accumulate, and the flue blocks - leading to smoke spillage indoors or dangerous backdrafting. We fabricate custom caps for non-standard sizes, one trip.
- Rusted-through flat caps on 1960s brick ranches. The original galvanized caps installed when these homes were built have long since corroded. Rainwater dumps directly onto clay flue tiles, accelerating spalling and mortar erosion. Heavy-gauge copper or stainless replacement is the only lasting fix.

FAQs - Chimney Cap & Crown in Lynwood
Probably not. Original dual-use flues in Lynwood’s 1950s-1970s ranches are typically oversized compared to modern single-use flues, and standard caps will gap or sit improperly. We measure on site and fabricate custom caps that seat correctly, preventing the moisture intrusion that destroys clay tiles. Call (888) 289-6055 for a free inspection and exact quote.
Lake Michigan moisture and aggressive freeze-thaw cycling accelerate corrosion of thin-gauge galvanized steel. Lynwood’s climate is harder on metal than drier inland suburbs. We use heavy-gauge copper and stainless steel from Copperfield and Gelco - materials built to survive decades here, not seasons. A proper cap costs more upfront and saves the chimney it protects.
Yes. We fabricate custom caps for non-standard flues, including outbuilding chimneys that never had proper protection. We’ll measure, build, and install in one visit. No cap means birds, debris, and water - all of which create fire and draft hazards. Call (888) 289-6055 to schedule.
Sometimes the cap is fine and the crown beneath it is cracked. Sometimes both need attention. We inspect with a Level-2 camera and document what we find. If the crown has surface cracking, coating may suffice. If water has penetrated to the flue structure, repair or rebuild is necessary. We’ll show you the photos and give you a plain-English verdict - no pressure, just facts. Estimates are free.
Very likely. Gas furnaces produce cooler exhaust that condenses heavily in oversized flues designed for oil heat. The wrong cap traps moisture or gaps and lets it in. We size caps for the actual flue and appliance combination, which often means a custom multi-flue cap with better ventilation geometry. This is one of the most common calls we get from Lynwood’s converted ranches. Call (888) 289-6055 - we’ll diagnose it properly.
