Chimney Crown Repair in Elk Grove Village: What You Need to Know

Chimney crown damage is one of the most common issues we find in Elk Grove Village. Elk Grove Village has many 1960s–70s ranch homes in its residential areas, with a housing stock that's now 50–60 years old. Proximity to O'Hare International Airport means some homes have experienced structural settling over the decades from ground vibration, which can affect masonry integrity and chimney alignment — creating offset liner joints that are invisible without a video inspection. We recommend Level 2 inspections for Elk Grove Village homes that haven't been professionally evaluated in the last 5 years. The Chicago area's 20–30 annual freeze-thaw cycles work relentlessly on chimney crowns, widening hairline cracks into major failures that allow water to infiltrate the masonry and cause expensive interior damage.

About Chimney Crown Repair

The chimney crown (sometimes called the chimney wash) is a sloped concrete or mortar slab that covers the top of the chimney, leaving only the flue opening exposed. It's designed to shed water away from the chimney and protect the brick and mortar below. A properly built crown extends slightly beyond the chimney's edge and slopes downward to direct water away. Over time, crowns crack due to thermal expansion and contraction, freeze-thaw cycles, and the natural settling of the chimney structure.

A cracked chimney crown is the #1 cause of water infiltration in chimneys. Once water gets through the crown, it can saturate the masonry, freeze and expand in winter, accelerate mortar deterioration, damage the flue liner, and eventually cause interior water damage to your home. In the Wheeling and northwest Chicago area, we experience 20–30 freeze-thaw cycles per winter — each one working to widen existing cracks. Addressing crown damage early, ideally in spring or fall before extreme temperatures arrive, prevents far more expensive repairs down the road.

Signs You Need It

  • Visible cracks running across the top of the chimney crown
  • Chunks of crown material missing or fallen onto the roof
  • Water stains on the interior ceiling or walls near the chimney
  • Efflorescence (white mineral deposits) on the chimney exterior
  • Spalling or crumbling brick just below the crown
  • Rust stains on the firebox or damper (sign of water entering the flue)

Our Process in Elk Grove Village

1

Crown assessment from the roof

We inspect the crown up close, documenting all cracks, missing sections, and the overall condition. We determine whether a crown coat sealant repair or a full crown replacement is the right approach.

2

Surface preparation

We clean the crown surface, remove all loose material, and prepare the substrate for repair. For full replacements, we remove the old crown entirely and clean the chimney top.

3

Repair or replacement

For minor to moderate cracking, we apply a professional-grade elastomeric crown coat sealant that bridges cracks and creates a flexible waterproof membrane. For severely damaged or improperly built crowns, we form and pour a new crown with proper slope and overhang.

4

Waterproofing treatment

We apply a breathable waterproofing sealant to the repaired or new crown and the surrounding masonry to provide long-term protection against moisture infiltration.
