HeatShield Chimney Cap & Crown Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

HeatShield Chimney Cap & Crown in Evanston: What to Know First

We provide independent HeatShield chimney cap and crown service across Evanston, from the historic lakefront district to the newer construction west of Ridge Avenue. Most HeatShield cap and crown jobs are diagnosed, quoted in writing, and completed within one to two visits - no deposit required before you see the scope and the price. We’re not affiliated with HeatShield Corporation; we’re an independent service provider who stocks the parts and knows the failure patterns.

Call (708) 234-1174

This page is for Evanston homeowners who already have a HeatShield product installed and need cap or crown work done right. If you’re seeing rust streaks, crown cracks, or a cap that’s lost its mesh tension, call us at (708) 234-1174. We’ll send a named, background-checked technician with a camera, and you’ll get a written price before anyone picks up a tool.

How HeatShield Products Fail - and How We Fix Them

  • HeatShield Pro-Series multi-flue caps in Evanston’s freeze-thaw zone. The Pro-Series uses a 24-gauge lid with welded corner seams. In Evanston, where lake-effect temperature swings hit 40 degrees inside 12 hours through February and March, those seams fatigue at the weld points. We see this on homes near Lighthouse Beach and the lakefront historic district more than inland. Our fix: seam-seal with high-temp silicone where intact, or source a replacement lid through our Haven buying network - we don’t weld-patch caps that have already cycled through two Evanston winters.
  • HeatShield UL-Listed single-flue caps with failed mesh. The 5/8-inch spark arrestor mesh on single-flue units loses tension after 6-8 years of thermal cycling. Once the mesh sags, it catches debris and restricts draft. We replace with OEM-spec mesh or, if the frame is still square, fit a Gelco aftermarket insert that matches the flue dimension exactly. Corrine Halstead keeps a sizing chart from jobs she’s refused to clear - the camera doesn’t negotiate, and neither does creosote - and we use that same rigor matching replacement mesh to flue opening.
  • HeatShield CrownSeal coating delamination on poured concrete crowns. CrownSeal is a brushable elastomeric product, not a cap. When applied over a crown with active spalling or without proper surface prep, it traps moisture and accelerates freeze-thaw damage. We see this on 1920s Evanston masonry where the original crown was poured with too little Portland cement. Our fix: remove the failed CrownSeal, grind to sound concrete, re-pour or patch with CrownCoat or a proprietary cementitious overlay, then cap with a vented unit that lets the crown breathe.
  • HeatShield chimney crown cracks at the flue interface. The crown should overhang the flue tile by minimum 2 inches with a drip edge. HeatShield crowns installed with insufficient overhang direct water straight to the brick-masonry joint. In Evanston’s older homes near Central Street, we’ve found original crowns poured directly against clay flue liners with no expansion gap. Thermal expansion cracks the crown at the liner. We cut a relief joint, install a flue-top gasket, and re-pour with proper slope and overhang.
  • HeatShield factory-built chase covers on prefab chimneys. These are galvanized or powder-coated steel tops, not true masonry crowns. The corner seams and center rib are leak points after 10-12 years. In Evanston’s tree-canopy neighborhoods like the one around Northwestern’s south campus, falling branch impacts dent the center rib and create pooling. We measure on-site and fabricate a replacement from 24-gauge stainless or copper through our Copperfield supply line, with cross-breaks to shed water and a screened ridge vent.
