Our Chimney Cap & Crown Services in Northbrook
Custom Cap Installation for Northbrook Acreage Properties
Northbrook’s rural-style lots, especially north of Dundee Road and along the western edges near the Cook County forest preserves, often feature detached workshops with chimneys that standard big-box caps simply don’t fit. We measure on-site, fabricate a custom cap from Copperfield or Gelco materials, and install it to withstand the heavier-duty conditions these outbuildings face. A proper custom cap prevents water intrusion, keeps animals out, and vents properly for the appliance below. Done right, and we stand behind it.

Crown Coating for Freeze-Thaw Protection
Northbrook sits 12 to 15 miles inland from Lake Michigan, close enough that persistent lake-effect moisture drives into every crack and pore of an unprotected crown. We apply a professional-grade Crown Coating, typically HeatShield or a compatible elastomeric sealant, that flexes with the masonry through 20 to 30 freeze-thaw cycles each season. A typical Crown Coating in Northbrook runs $180 to $450 depending on crown size and condition. The coating adds years of service to a crown that would otherwise spall and crack.

Multi-Flue Cap Replacement
Many Northbrook homes, particularly the 1960s and 1970s Colonials and ranches with multiple fireplaces, were built with multi-flue chimneys. The original caps on these chimneys are often rusted through, improperly sized, or missing entirely. We install multi-flue caps from Olympia Chimney or Famco that cover all flues with a single, properly vented unit. On a large property on Lake Avenue in Northbrook, we replaced a failed multi-flue cap on a workshop chimney that had been battered by lake-effect moisture. The original cap was undersized for the heavy doors below, so we installed a custom copper cap from Copperfield, paired with a Crown Coating to seal the crown against Northbrook’s freeze-thaw cycles. A square deal: no surprises on the bill.

Crown Repair for Gas-Insert Conversion Damage
Here’s the problem we find again and again in Northbrook. In the 1980s and 1990s, homeowners converted wood-burning fireplaces to gas inserts. The installer left the original large-diameter clay tile liner in place. The cooler, wetter exhaust from a gas appliance condenses inside that oversized flue, silently eroding the liner and mortar from the inside out. The damage migrates upward, deteriorating the crown from below. This failure mode only shows up on a proper Level-2 camera inspection, and it is endemic to this era of North Shore suburb conversion work. We repair the crown, address the underlying moisture issue, and document everything with photos you can see.

Common Chimney Cap & Crown Problems We See in Northbrook Homes
- Gas-insert condensation eroding crowns from within. The oversized clay tile liners left in place during 1980s-90s conversions trap moisture against the crown’s underside. We find this in ranch homes throughout Northbrook’s 60062 zip code, often where the homeowner had no idea anything was wrong until water stained the ceiling.
- Undersized caps failing on detached workshop chimneys. Northbrook’s acreage properties often have outbuilding chimneys that were capped with whatever was cheapest at the time. Those caps can’t handle the wind exposure and thermal cycling of a standalone structure. We replace them with properly sized, heavy-duty units.
- Lake-effect moisture accelerating spalling and efflorescence. Northbrook’s position relative to Lake Michigan means more freeze-thaw stress than communities farther inland. Uncoated crowns show visible deterioration within five to seven years instead of fifteen.
- Original concrete crowns reaching end of service life. The 1960s and 1970s Colonials and split-levels that dominate Northbrook were built with crowns that have now endured 50-plus years of northeastern Illinois weather. Hairline cracks widen, the concrete surface flakes away, and water finds its way to the brick below.

FAQs - Chimney Cap & Crown in Northbrook
It accelerates rust on metal caps and spalling on concrete crowns by driving repeated freeze-thaw cycles through the masonry. Northbrook’s proximity to Lake Michigan means your chimney faces 20 to 30 freeze-thaw events per season, more than inland communities see. A properly coated crown and a correctly sized, well-vented cap are your best defense. Call (888) 289-6055 for an inspection and we’ll show you exactly what your chimney is facing.
The original oversized clay tile liner left in place during 1980s-90s conversions causes condensation that erodes the crown from the inside out. This is a Northbrook-specific failure pattern we document regularly on Level-2 camera inspections. The damage is hidden until it’s advanced. If your home had a gas insert installed during those decades, a camera inspection is the only way to know your crown’s true condition. Estimates are free.
A custom-fabricated cap in stainless steel or copper, properly sized for the flue and the structure’s wind exposure. Standard caps fail prematurely on detached workshops because they can’t handle the thermal cycling and aren’t sized for the heavier-duty use these outbuildings often see. We measure on-site and fabricate from Copperfield or Gelco materials. Call (888) 289-6055 to schedule a measurement.
A well-built concrete crown with proper coating should last 15 to 20 years in Northbrook’s climate, but many original crowns from the 1960s and 1970s are now past that mark. If your crown is uncoated, shows hairline cracks, or your home had a gas-insert conversion, inspect it now regardless of age. We’ll be there when we say, and we’ll give you a plain-English verdict with photos you can see.
Yes. A new crown without coating will begin absorbing moisture immediately, and Northbrook’s lake-effect freeze-thaw cycles will start the damage within the first few seasons. We coat every crown we build or repair as standard practice, using materials that flex with temperature swings. The coating is built into our full crown rebuild pricing.
