HeatShield Chimney Cap & Crown Nationwide

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

We provide independent HeatShield chimney cap and crown service in Paterson, with most inspections booked within a few days and repairs wrapped in a single visit when parts are on hand. A standard HeatShield cap replacement runs $340-$620; crown coating or repair with HeatShield-compatible materials typically falls between $280-$550. We do not quote over the phone for anything we have not seen, because a cap that looks fine from the ground can hide a cracked crown underneath.

Call (973) 604-2986

This page is for Paterson homeowners who already have HeatShield components on their chimney and need to know whether to repair, replace, or upgrade. If you are in Eastside, the Hillcrest area, or near Garrett Mountain and your cap is rattling, rust-streaked, or letting water past the crown, call us at (973) 604-2986. A live person answers, and we will get you on the schedule.

How HeatShield Products Fail - and How We Fix Them

• HeatShield Pro-Series multi-flue caps with welded-seam lid fatigue. The Pro-Series uses a stamped lid with spot-welded corners. After eight to twelve Paterson winters of freeze-thaw cycling, especially on south-facing chimneys that heat and cool daily, those welds crack at the drip edge. Water gets behind the cap and saturates the crown underneath. We pull the cap, inspect the crown with a camera, and either re-weld the corner with stainless rod or source a replacement lid that matches the existing base rail so you are not buying a full assembly you do not need.
• HeatShield UL-listed galvanized caps with base rail corrosion. The galvanized line is rated for exterior use, but the base rail sits in a pool of acidic condensate when a chimney is oversized for the appliance. In Paterson’s older brick homes with unlined or partially lined flues, this is common. The rail corrodes from the inside out, and the cap loosens in high wind. We replace with a 304 stainless base rail, or if the flue tile is still sound, we step up to a HeatShield stainless cap that will outlast the next two furnaces.
• CrownSaver coated crowns with surface spalling under the cap flange. CrownSaver is a cementitious coating, not structural concrete. When the original crown was too thin to begin with, the coating follows the cracks that form underneath. The cap flange traps water at the edge, and you get a ring of spalling concrete that looks like cap failure but is actually crown failure. We remove the cap, grind back to sound substrate, and either re-coat with CrownSaver where the crown has enough mass or pour a new crown if the structural integrity is gone.
• HeatShield single-flue caps with incorrect mesh sizing for the flue. The 5/8-inch mesh on standard HeatShield caps is fine for wood-burning fireplaces, but Paterson homeowners who have converted to gas inserts often still have the original cap. The mesh is too coarse to stop squirrel nesting, and too fine to let the lower exhaust temperatures of gas vent properly. Moisture condenses, the cap rusts from the inside, and the crown takes the damage. We match the mesh to the fuel type, or switch to a Gelco or DuraFlex cap with the correct spark arrestor and venting profile.
• HeatShield chase covers on prefab chimneys with improper pitch. The factory chase cover is flat or nearly flat. Snow loads in Passaic County, especially the wet, heavy stuff that comes in March, pond on the cover and forces water through the screw holes. The crown underneath, often just a poured slab on a framed chase, softens and the chimney pipe tilts. We replace with a properly pitched chase cover, sealed with heat-rated silicone, and verify the crown is still level enough to support the new cover without stress.

Our HeatShield Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks what you are seeing, and books a Level-2 camera inspection. We do not guess at prices before we see the chimney.
2. 2
   Inspection and documentation. Our technician arrives in a marked truck, uniformed, and runs a camera up the flue and across the crown. You get photos on a tablet and a plain-English verdict: what is wrong, what caused it, and what happens if you wait.
3. 3
   Parts decision. If the cap is salvageable, we say so. If it needs replacement, we explain the trade-off between OEM HeatShield parts and quality aftermarket equivalents from Gelco or DuraFlex. Some HeatShield warranties require OEM; some do not. We tell you which applies.
4. 4
   The repair. Most cap replacements and crown coatings take two to four hours. We tarp the roofline, protect your landscaping, and clean the flue if creosote is present. The job is not done until the cap is secure and the crown sheds water.
5. 5
   Testing and photos. We run water over the crown and cap joint, check for infiltration, and take after photos. You see the same angles as the before shots.
6. 6
   Written guarantee. You get an invoice that matches the estimate and a 90-Day Done Right Promise in writing. If water gets past our repair, we come back. No paperwork to dig up, no arguing.

What HeatShield Chimney Cap & Crown Costs in Paterson

These are real numbers for Paterson homes we have worked on, from the two-story brick colonials near Eastside Park to the hillside ranches around Garrett Mountain. Steep roofs, multiple flues, or a crown that has been leaking unnoticed for two seasons will push you toward the higher end. We give you the full price before we start, and that is the price on the invoice. Call (973) 604-2986 for a free estimate.

Why Paterson Homeowners Call Hearthstone Chimney Co. for HeatShield Work

We are not a chain, and we are not a one-truck operator who might answer the phone next year. Hearthstone Chimney Co. has been in Passaic County for over 42 years, and Russell Haines has spent the better part of two decades working chimneys from Eastside to the blocks around Garrett Mountain. We know which Paterson neighborhoods have the 1920s brick with the shallow crowns, and which have the 1970s prefabs with the rotted chase covers.

Our technicians carry HeatShield, DuraFlex, Gelco, and Olympia Chimney parts on the truck, so we are not ordering after the fact and making you wait. Every job gets the 90-Day Done Right Promise in writing. If it is not right, we make it right. No arguing. Photos you can see, a plain-English verdict, and a square deal on the bill. That is how we have stayed in business since 1984.
