We’ve been driving to Highland for over 42 years. We know the 1950s brick ranches along Ridge Road, the two-story colonials near Main and 41st, and the cape cods tucked behind the commercial corridor on 45th. These homes share one thing: original masonry chimneys built for coal or fuel-oil heat, now serving natural gas or wood-burning fireplaces with flue liners that were never designed for the job. That mismatch is why Highland chimneys fail differently than chimneys anywhere else in the region.

Our Chimney Cap & Crown Services in Highland
Crown Repair
Crown repair is what we recommend for Highland chimneys with hairline cracking that’s still confined to the surface layer. On a 1962 brick ranch near the corner of 45th and Johnson, we replaced a crumbling crown that had let water pool inside an oversized clay liner originally built for an oil furnace. After installing a custom copper cap from Copperfield and sealing the crown with HeatShield coating, the homeowner saw immediate cessation of spalling on the north-facing brick face.
Most Highland crown repairs run $380-$720. We grind out the damaged material, apply a bonding agent, and rebuild with professional-grade CrownCoat or HeatShield products formulated for Lake County’s freeze-thaw cycling. The work takes 3-4 hours and carries our 90-Day Done Right Promise.
Custom Cap
Highland’s legacy fuel-oil soot deposits corrode standard galvanized caps faster than normal. We specify 304-grade stainless or copper caps from Copperfield and Gelco for this market. Custom caps are measured and fabricated to your flue dimensions, not pulled from a box of standard sizes.
A custom cap installation in Highland ranges from $340-$580 for stainless, or $680-$1,200 for copper. The cap prevents water entry, blocks animal intrusion, and reduces downdraft on windy days coming off Lake Michigan. For homes with oversized clay liners, the right cap with proper screening also improves draft performance.
Crown Coating
Crown coating is our preventive service for Highland chimneys with sound structural crowns but porous, weathered surfaces. We apply HeatShield or CrownCoat sealers that flex with temperature swings and resist the moisture absorption that destroys crowns in this lake-effect climate.
Coating alone runs $280-$450. We only recommend it when the crown’s structural integrity is intact. If the crown is cracked through or separating from the brick, coating is a waste of money and we’ll tell you so. A square deal: no surprises on the bill.
Cap Replacement
Standard cap replacement in Highland is $240-$420. We see this most often on homes where the original cap blew off in a windstorm or corroded through at the mesh. We stock common sizes for Highland’s mid-century flue configurations, so most replacements are same-day.

Trusted Brands We Service in Highland
We work exclusively with professional-grade materials: DuraFlex liners, HeatShield coating systems, Gelco and Copperfield caps, and Olympia Chimney components. These aren’t builder-grade substitutes. We keep Highland-appropriate inventory on our trucks, including oversized cap adapters for the 9×13 and 13×13 flue tiles common in Highland’s 1950s-1970s housing stock. That means faster turnaround and no waiting for special-order parts that don’t fit your chimney.
Common Chimney Cap & Crown Problems We See in Highland Homes
- Oversized clay liners trap moisture that destroys crowns from below. Highland’s original flue liners, built for oil furnaces, are too large for modern gas appliances. The resulting condensation saturates the mortar crown, causing hairline cracks that are invisible from the ground until water stains appear on your top-floor ceiling.
- Freeze-thaw cycling attacks north and west faces first. Lake Michigan moisture drives repeated freezing and thawing deep into mortar joints. On 1950s brick capes with unreinforced crowns, we’ve measured spalling rates twice as high on north-facing exposures compared to south-facing chimneys in the same neighborhood.
- Legacy fuel-oil soot corrodes standard caps. The sulfuric acid residue in Highland’s older flues eats through galvanized steel in 3-5 years. We specify 304-grade stainless or copper from Copperfield and Gelco to resist this chemical attack.
- Crown separation from the brick course. Many Highland crowns were poured without proper overhang or drip edge detail. Water runs straight down the brick face, accelerates spalling, and eventually undermines the crown’s bond to the chimney. We see this most on colonials near Main and 41st.

FAQs - Chimney Cap & Crown in Highland
The culprit is almost always the oversized clay flue liner inside. Highland’s original liners, built for fuel-oil or coal appliances, are too large in diameter for modern natural gas units. The lower exhaust temperatures cause chronic condensation that seeps upward into the mortar crown from below, creating freeze-thaw cracks invisible until they leak. Call (888) 289-6055 for a Level-2 camera inspection that will show you exactly what’s happening inside your flue.
If the copper cap is structurally sound but leaking at the seams or base flashing, repair is usually cost-effective at $180-$340. If the mesh is corroded through, the base is warped, or the cap was improperly sized for your flue, replacement with a new custom copper cap from Copperfield runs $680-$1,200 and will outlast the repair. We’ll photograph both options and give you an honest recommendation.
Yes, if you have multiple flues terminating on the same chimney. A multi-flue cap protects unused flues from water and animal entry, which is significant in Highland where squirrels and raccoons are active year-round. For a single-flue chimney, a standard custom cap is the better value. Multi-flue caps run $580-$1,100 installed.
Highland’s lake-effect moisture produces roughly 30-40% more freeze-thaw cycles per winter than Indianapolis. A hairline crack that might take 4-5 years to propagate in a drier climate can become a through-crack in 2-3 years here. North-facing chimneys in Highland show the fastest deterioration. Annual inspection is the only way to catch crown damage before it requires full replacement.
Sometimes, but we won’t recommend it if the liner is the root cause of crown failure. If your oversized clay liner is actively condensing moisture into the crown, a new crown will crack the same way. Our Level-2 inspection determines whether crown-only repair is viable or if liner stabilization with DuraFlex is the smarter long-term fix. We’ll show you the photos and explain both paths. Call (888) 289-6055 for a free estimate.
