Fast, Reliable Chimney Cap & Crown Across Lombard
Chimney cap and crown repair in Lombard typically runs $340-$890 depending on whether you need a simple cap replacement or full crown rebuild, and most jobs are completed in a single visit. If you’re seeing water stains on your ceiling near the chimney, hearing debris tumble down the flue, or noticing rust on your firebox, the cap or crown is likely the culprit. Call (888) 289-6055 - a live person answers 24 hours a day, and we’ll have a technician to your Lombard home fast.
We’ve worked on chimneys along St. Charles Road, in the ranch neighborhoods south of Roosevelt Road, and throughout the older blocks near Main Street for over 42 years. Our Chimney Cap & Crown team knows the difference between a quick cap swap on a 1990s split-level and a full crown rebuild on a 1958 ranch with original clay tile. That matters because the wrong fix on the wrong chimney wastes your money and leaves the real problem untouched.

Our Chimney Cap & Crown Services in Lombard
Crown Repair
The concrete crown at the top of your chimney is the only thing keeping rain from pouring down the flue and rotting the liner from the inside. In Lombard’s mid-century ranch and Cape Cod homes, we see crowns that have cracked through 30-40 freeze-thaw cycles every winter, splitting along the edge where the crown meets the brick. A proper crown repair isn’t caulk from a hardware store. We form and pour a new concrete crown with the correct slope and overhang, or apply a professional-grade crown coating when the damage hasn’t reached the structural layer. Most crown repairs in Lombard run $480-$720.
Crown Coating
When the crown has hairline cracks and minor spalling but hasn’t separated from the brick, a crown coating can add 10-15 years of life without the cost of full replacement. We use flexible, breathable coatings designed for Chicago’s climate - not the rigid products that crack again after the first hard freeze. Crown coating in Lombard typically costs $340-$520. It’s the right choice for homeowners on the south side of the village whose 1960s ranches still have solid crown bases but need protection before the next winter.
Multi-Flue Cap Installation
Older Lombard homes near the St. Charles Road and Main Street corridors often have multi-flue chimneys that served both a fireplace and a furnace. These chimneys need custom multi-flue caps that cover the entire crown, not just individual flue pipes. We fabricate and install stainless steel multi-flue caps from Olympia Chimney that are measured to your chimney’s exact dimensions. A custom multi-flue cap in Lombard runs $620-$890 installed, including proper fastening and counter-flashing to keep wind-driven rain out.
Cap Replacement
Galvanized steel caps last 5-7 years in Lombard’s wet winters before rusting through. Stainless steel or copper caps last decades. We replace corroded caps with properly sized units that allow adequate draft while keeping squirrels, raccoons, and rain out of your flue. Standard single-flue cap replacement in Lombard costs $280-$440. If your cap is the wrong size for your flue - common on homes that converted from oil to gas - we’ll tell you and size it correctly.

Common Chimney Cap & Crown Problems We See in Lombard Homes
- Freeze-thaw cracking in single-wythe brick chimneys. Lombard’s ranch and Cape Cod neighborhoods are full of chimneys built with a single layer of brick. These stacks absorb water through porous mortar joints, then the water freezes and expands through 30-40 cycles each winter. The crown lifts. The brick faces spall. We’ve rebuilt crowns on homes along Roosevelt Road where the original crown had separated entirely from the stack.
- Oversized clay tile liners destroying mortar from inside out. This is the failure mode that newer suburbs simply don’t see. In Lombard’s 1950s-1970s ranch homes, the original 8-inch clay tile liner was sized for an oil boiler. Today’s high-efficiency gas furnace needs only 4-6 inches. The oversized flue moves too slowly, trapping acidic condensate that dissolves the mortar between tile sections. The crown loses its internal support and cracks. You won’t see this until a camera inspection reveals the damage.
- Galvanized caps rusting through in 5-7 years. Chicago’s wet winters and heavy freeze-thaw exposure chew through cheap galvanized caps fast. We replace them with stainless steel or copper caps from Gelco and Olympia Chimney that withstand Lombard’s climate for the life of the chimney.
- Crown separation due to improper original construction. Many Lombard crowns were poured without a bond break between the crown and the flue tile, or without the required slope to shed water. Water pools, freezes, and pushes the crown away from the flue. We see this constantly in the postwar neighborhoods south of the Eisenhower.

What moves the number? Height and access matter - a two-story colonial on a narrow lot costs more than a single-story ranch with clear roofline access. The extent of hidden damage matters more. We’ve opened crowns in Lombard that looked sound from the roof but concealed rotted liner support underneath. That’s why we inspect with a camera before we quote. The estimate is free, and the number we give you is the number on the invoice. Call (888) 289-6055 for an exact quote on your chimney.

FAQs - Chimney Cap & Crown in Lombard
Yes, almost certainly. The original 8-inch clay tile liner in your 1950s-1970s Lombard ranch was designed for an oil or coal boiler. Your modern high-efficiency gas furnace needs a 4-6 inch liner. The oversized flue moves exhaust too slowly, trapping acidic condensate that dissolves mortar from the inside out and destroys the crown’s support structure. We verify this with a Level-2 camera inspection and can reline with DuraFlex to match your appliance’s output. Call (888) 289-6055 - the inspection is $280-$340 and the estimate for any work is free.
A galvanized steel cap lasts 5-7 years in Lombard’s wet, freeze-thaw climate before rusting through. A stainless steel or copper cap lasts 20+ years with proper installation. We inspect cap condition during every chimney service and replace them before they fail and let water into the flue. If your cap is more than five years old and showing rust streaks on the chimney face, it’s time. Call (888) 289-6055 and we’ll check it at no charge with any other service.
Freeze-thaw cycling is the primary cause - water enters tiny cracks, expands when frozen, and widens them through 30-40 cycles each Lombard winter. Poor original construction accelerates this: crowns poured without proper slope, without a bond break around the flue tile, or with too little Portland cement in the mix. The oversized flue liner problem common in Lombard’s postwar homes adds internal mortar destruction that undermines the crown from below. We determine which cause is active with camera inspection and photos you can see.
If your chimney has two or more flues - typical of pre-1950 homes near Main Street and St. Charles Road, or any home where fireplace and furnace share one stack - a custom multi-flue cap is the correct solution. Individual flue caps leave the crown exposed to rain and don’t protect the space between flues where debris collects. We measure your chimney on-site and fabricate a stainless steel multi-flue cap from Olympia Chimney that covers the entire crown. Installation runs $620-$890 in Lombard.
Water stains on the ceiling near the chimney, pieces of concrete or mortar in the firebox, rust on the damper or firebox walls, and visible cracks or separation on the crown surface seen from the ground with binoculars. In Lombard’s older homes, we also find that a sudden draft problem or odor from the fireplace can signal crown failure letting water into the flue system. If you see any of these, call (888) 289-6055 - we’ll inspect with a camera, show you the photos, and give you a plain-English verdict with upfront pricing.
