Chimney Relining in Norwalk, CT

A Properly Sized Liner = Safer Venting, Stronger Draft, Longer Chimney Life

Your chimney liner is the pathway that carries smoke and combustion gases out of your home. When it’s cracked, missing, or the wrong size, performance and safety suffer—draft weakens, odors increase, and heat or moisture can damage masonry. Norwalk Chimney Specialists installs high-quality stainless-steel chimney liners throughout Norwalk, CT, matched to your specific appliance and flue height for reliable, efficient venting.

We evaluate the entire system—appliance BTU output, connector diameter, flue height, offsets, and termination—to select the correct liner type and insulation method. Our goal is to improve draft, reduce creosote, and protect your home’s structure from the inside out. If you’ve noticed smoke roll-outs, difficulty lighting, or persistent odors, a liner assessment can be the fastest path to a permanent fix.

When Do Norwalk, CT Homes Need Chimney Relining?

• Cracked, missing, or damaged clay flue tiles
• Converting to a new appliance (stove, insert, or gas log set)
• Persistent drafting problems or smoke spillage
• After a chimney fire or severe weather damage
• To meet manufacturer- or code-required flue sizing

Stainless-Steel Liner Options

We install UL-listed stainless-steel liners sized and configured for your fuel type and appliance:

We also provide rigid and flex liner systems. Rigid sections deliver superior draft in straight flues; flexible liners navigate offsets and tight masonry. Where codes or best practices require, we add insulation wrap or pour-in insulation to maintain flue gas temperatures, stabilize draft, and reduce condensation.

Why Liner Sizing Matters

Draft relies on warm, rising gases traveling up a properly sized and heated flue. Oversized flues cool gases too quickly, leading to heavy creosote deposits and poor performance. Undersized flues can cause smoke roll-outs and soot staining. We calculate liner diameter based on appliance output and flue height to hit the sweet spot for clean combustion and responsive draft—especially important in Norwalk’s coastal climate, where wind and humidity can complicate venting.

Our Chimney Relining Process

1. Assessment & Photos: Inspect current liner/tiles, appliance specs, and termination. Document issues.
2. Sizing & Plan: Calculate liner diameter, choose 316Ti or 304, determine rigid vs. flex and insulation needs.
3. Prep & Cleaning: Sweep the flue, remove obstructions, and prepare the top and base for installation.
4. Liner Install: Lower liner, connect to appliance, secure at top with a top-plate, storm collar, and cap.
5. Seal & Insulate: Add insulation (wrap or pour) where required for performance and code compliance.
6. Final Test: Check draft, verify connections, and provide completion photos and usage guidance.

Relining for Wood, Gas & Oil

We reline systems serving open fireplaces, wood stoves, gas inserts, boilers, and furnaces. For gas appliances, correct sizing and smooth interiors reduce condensation and soot. For wood-burning systems, insulated liners help maintain hotter flue gases, decreasing creosote formation and improving overall efficiency.

Addressing Odors, Smoke, and Moisture

If you experience musty smells after rain, smoke backing up when lighting, or black residue on the face of your fireplace, your liner may be part of the problem. A properly sized and insulated liner stabilizes draft and reduces condensation—two major contributors to chimney odors and staining.
