HYDROPHOBIC PERMEABLE MOISTURE DEFENSE

CHIMNEY WATER PROTECTION.
CROWN REPAIR & SEALING.

Engineered moisture mitigation combining reinforced concrete crowns, custom lead counter-flashing, and breathable water repellent barriers.

Breathable Water Repellent Reinforced Concrete Cast Crown Step & Counter Flashing Satisfaction & Workmanship Guarantee
THE NUMBER ONE ENEMY OF CHIMNEYS

Water Causes 90% of All Chimney Failures

Water penetrates chimneys from three critical failure points: a cracked concrete crown wash, rusted or separated roof flashing, and porous brickwork that absorbs rain like a dry sponge.

Cheap silicone sealers trap internal moisture behind the brick face, causing interior wall rot and accelerated spalling. Absolute Chimney Pros utilizes breathable water-repellent treatments that repel liquid water from the outside while allowing internal moisture vapor to escape freely.

✓ Cast-In-Place Reinforced Crowns: 3+ inch thick fiber-reinforced concrete slabs with overhang drip edges.
✓ True Lead & Copper Counter-Flashing: Cut directly into mortar joints to establish a watertight roof seam.
✓ Breathable Water Repellent Shield: Deep-penetrating protection that helps protect masonry without altering brick color.

SYSTEMIC PROTECTION

The Three Moisture Defense Barriers

We inspect and seal every entry point from the top slab to the roof decking.

👑 1. The Crown & Wash

The top concrete slab that sheds water away from the flues. We repair minor cracks with elastomeric CrownCoat or pour new reinforced overhang crowns.

🧱 2. Breathable Masonry Repellent

Breathable waterproofing penetrates into brick pores to repel driving rain while allowing trapped moisture to evaporate outward.

📐 3. Roof Flashing Interlock

We replace deteriorated roof tar with custom-bent step-and-counter lead or copper flashings ground into mortar bed joints.

FREQUENTLY ASKED QUESTIONS

Chimney Waterproofing FAQs

Never. Deck sealers, silicone coatings, and exterior paints create an impermeable film that traps water vapor inside the brick. When temperatures drop below freezing, the trapped water expands and blows the brick faces completely off. Only breathable, water-repellent formulas formulated for masonry should be applied to chimneys.

Ceiling leaks near the chimney are almost always caused by failed roof flashing, separated mortar reglets, or a cracked crown that allows water to run down the exterior masonry into the attic framing. We perform water testing to locate and permanently seal the leak source.

Our commercial-grade breathable waterproofing treatments provide durable multi-season protection against moisture penetration without blistering or peeling, backed by our Satisfaction & Workmanship Guarantee.
