CUSTOM CHIMNEY CAPS & energy top-sealing dampers

Fabricated stainless steel and solid copper chase caps, multi-flue spark arrestors, and top-sealing dampers designed to stop water intrusion, animal entry, and energy loss.

ARCHITECTURAL PROTECTION
“A chimney without a cap is an open hole into your home. A single heavy rainstorm can deposit gallons of water directly onto your firebox and flue tiles.”

Water is the mortal enemy of chimney masonry. Without a precision-fitted cap, rain mixes with sulfurous soot to form hydrochloric and sulfuric acids that eat away mortar and clay flue linings.

We design and install custom-measured stainless steel and solid copper chase covers that shelter multiple flues, incorporate spark-arresting mesh, and feature top-sealing silicone rubber gaskets that eliminate costly winter draft loss.

Perimeter silicone bedding accommodates thermal expansion while stopping wind-driven rain.

TECHNICAL INQUIRIES

FREQUENTLY ADDRESSED QUESTIONS

Traditional throat dampers are loose-fitting cast iron plates that leak up to 8% of a home's conditioned heating up the chimney. Top-sealing dampers create an airtight rubber seal at the very top of the stack, keeping heated air in and freezing drafts out.
No. CSIA-compliant caps are engineered with calculated free-air ratios that allow flue gases to draft freely while blocking rain and wind downdrafts.
Yes. We custom fabricate solid architectural copper caps and chase covers that develop a rich natural patina over time while providing lifetime durability.
