Chimney Repair & Repointing in Norwalk, CT

Leak Stops, Structural Repairs, and Long-Lasting Masonry Work for Norwalk Homes

When a chimney leaks or starts to crumble, the problem rarely fixes itself. Connecticut’s coastal weather—wind-driven rain, salty air, and rapid freeze-thaw cycles—accelerates wear on mortar joints, crowns, and metal components. Norwalk Chimney Specialists restores performance and protects your home with precise, durable repairs tailored to Norwalk, CT conditions.

We begin with a thorough assessment to pinpoint root causes: failed flashing, cracked crowns, spalled brick, missing caps, or liner defects. Then we present photos and an itemized scope so you can prioritize confidently. Our crews use chimney-grade materials—polymer-modified crown mortar, flashing membranes, stainless steel hardware, and breathable waterproofing—to ensure your investment stands up to New England winters.

Common Chimney Repairs We Perform in Norwalk, CT

• Repointing (Tuckpointing): Replace deteriorated mortar joints to restore structural integrity and weather resistance.
• Crown Rebuilds: Correct slope, add proper drip edges, and use crack-resistant mixes to keep water out of the flue chase.
• Leak Diagnostics & Repair: Track moisture entry points and fix with sealing, repointing, crown work, or flashing replacement.
• Flashing Repair/Replacement: Remove failing step/counter-flashing and install new metal with premium sealants and underlayment.
• Cap & Chase Cover Installs: Stainless caps and custom chase covers to block rain, animals, and debris.
• Brick Replacement: Swap out spalled or fractured units and blend new brick to match existing masonry.
• Waterproofing: Apply breathable, siloxane-based treatments that repel water without trapping moisture.

Masonry Repointing: Small Joints, Big Protection

Mortar is the first line of defense against water. As it weathers, tiny gaps form and allow water to wick into the brick. During winter, that moisture freezes and expands—popping faces off bricks (spalling) and enlarging cracks. Our repointing process removes loose material to a proper depth, matches mortar color and composition, and tools joints for a tight, clean finish. The result is a stronger, more weather-tight chimney that resists leaks and heat loss.

Crown Repair & Rebuilds

A failing crown is one of the most common sources of leaks in Norwalk, CT. Hairline cracks, improper slopes, and missing drip edges funnel water into the chimney, where it can damage liners and interior walls. We rebuild crowns with fiber-reinforced mixes, form correct overhangs, and create drip edges that shed water away from the brickwork. For minor cracking, we may apply elastomeric crown sealants after surface prep to extend service life.

Chimney Flashing that Actually Seals

The intersection of roof and chimney is a notorious leak point. We install step and counter-flashing in accordance with roofing best practices, integrating underlayment membranes and sealing fasteners. Where previous tar “patches” were used, we remove failed material and start fresh with proper metalwork so you get a lasting, warrantied solution.

Stop Water Before It Starts: Caps, Chase Covers & Waterproofing

Rain entry accelerates interior deterioration and creosote odors. Stainless steel caps keep out weather and wildlife, while custom-fabricated chase covers protect factory-built systems. Finally, a professional waterproofing treatment helps brick shed bulk water while allowing vapor to escape—critical for long-term masonry health in Connecticut’s climate.
