Waterproofing Newly Constructed Chimney
A newly built masonry chimney is immediately vulnerable to water infiltration through porous brick, mortar joints, and unprotected crown and flashing connections.
Our team applied a complete, multi-layer chimney waterproofing system — sealing the crown, installing step and counter flashing, and applying vapor-permeable siloxane sealant — to deliver lifetime protection from the first day forward.
Restoring Structural Integrity and Preventing Future Water Intrusion
Newly constructed masonry chimneys are highly porous — brick and mortar absorb water immediately upon exposure. Without proper sealing, moisture infiltration begins within the first rain cycle, accelerating long-term deterioration.
We built and sealed a concrete chimney crown with elastomeric coating, installed step and counter flashing, added a stainless steel chimney cap, and applied a vapor-permeable siloxane sealer to all exposed masonry.
Comprehensive chimney waterproofing system including a two-coat elastomeric crown coating, step and counter flashing system, stainless steel chimney cap, and a vapor-permeable siloxane masonry sealer.
A fully waterproofed chimney system built for long-term performance—breathable masonry, flexible flashing joints, and a sealed crown designed to shed water and resist freeze-thaw damage.
Before
Exposed new masonry — porous brick and mortar joints unprotected from rain infiltration.
After
Sealed crown, installed flashing, stainless cap, and vapor-permeable sealant — fully protected.
A Step-by-Step Restoration Process Built to Last
Every project follows a proven process to ensure proper preparation, waterproofing, and long-term durability. Here’s how we waterproofed this newly constructed chimney.

FINISHING & FINAL RESULT
1
INITIAL CONDITION & ASSESSMENT
We inspect all chimney components — brick, mortar joints, crown form, roof junction, and flue — to map every vulnerability before any work begins.
2
DEMOLITION & SURFACE REMOVAL
A sloped concrete crown is formed to overhang the chimney edges. Two coats of sealer are applied for a flexible, waterproof membrane.
3
SURFACE PREPARATION & SETUP
L-shaped step flashing is woven into shingle courses, with counter flashing set into mortar joints and sealed for a watertight overlap.
4
WATERPROOFING SYSTEM INSTALLATION
5
FINISHING & FINAL RESULT
Every sealed surface, flashing joint, and crown edge is now fully protected, it repels water without trapping moisture inside.
1
INITIAL CONDITION & ASSESSMENT
We perform a detailed inspection to identify water intrusion points, evaluate structural conditions, and determine the best restoration approach.
2
DEMOLITION & SURFACE REMOVAL
A sloped concrete crown is formed to overhang the chimney edges. Two coats of sealer are applied for a flexible, waterproof membrane.
3
SURFACE PREPARATION & SETUP
L-shaped step flashing is woven into shingle courses, with counter flashing set into mortar joints and sealed for a watertight overlap.
4
WATERPROOFING SYSTEM INSTALLATION
A chimney cap is installed to block rain and debris, and a sealer is applied across all masonry surfaces for protection.
5
FINISHING & FINAL RESULT
Every sealed surface, flashing joint, and crown edge is now fully protected, it repels water without trapping moisture inside.
