That practice started in 2009 and became Clause 4 of the Haven Standard. You won’t find “call for quote” anywhere on our site because our entire business model is a written price before any work starts.

What Our Chimney Liner & Rebuild Service Includes

Stainless Steel Liner

A stainless steel liner is a rigid or flexible pipe installed inside your existing flue when the original clay tile has cracked, separated, or deteriorated to the point where it can no longer contain heat and combustion gases. We use DuraFlex and Copperfield liners exclusively because they carry lifetime warranties and hold up to the freeze-thaw cycles we see in Greenwich, where chimneys go from 15 degrees to 50 degrees inside a single February week. Our technicians measure the flue with a laser, cut the liner to exact length, and insulate the annular space where code requires it.

Flexible Liner

A flexible liner is the same stainless steel material but built with a corrugated profile so it can snake through flues with offsets, smoke-shelf obstructions, or existing masonry that isn’t perfectly plumb. We specify flex liners for fireplaces and wood stoves where a rigid section won’t navigate the throat cleanly. The flex liner is secured at the top with a proper plate and rain cap, then connected to the appliance collar at the bottom. Everything is documented with photos at both ends.

Liner Replacement

Liner replacement means removing the old clay or metal liner entirely and installing a new system. Most Greenwich homes built before 1980 have terra cotta liners that crack at the mortar joints after 40 to 50 years of thermal stress. We break out the old tiles where it’s required, size the new liner to match your appliance’s BTU output, and leave you with a written record showing the old liner next to the new one. If the old liner is mostly intact but has one or two cracked joints, we’ll tell you plainly and give you the option of a targeted repair with HeatShield resurfacing instead of a full replacement.

Partial Rebuild

A partial rebuild addresses the section of the chimney that has failed most often the top five to ten courses of brick, the crown, and the flashing assembly while leaving the lower masonry intact. In Cos Cob and Riverside we regularly see chimneys where the top courses have spalled badly from water intrusion but the lower flue is still structurally sound. We take the chimney down to clean, undamaged brick, rebuild with matching or complementary brick, pour a proper concrete crown with a drip edge, and install new flashing. The repair line is always documented with before and after photos.

Full Chimney Rebuild

A full rebuild starts at the roofline and reconstructs the entire chimney from the crown down to the firebox. You need this when the mortar has lost so much lime that the masonry is no longer supporting itself, when multiple flue tiles have collapsed, or when a chimney fire has compromised the structure. We build to NFPA 211 dimensions for clearances and flue sizing. A full rebuild in Greenwich is a three to seven day job and includes a new crown, new flashing, new flue liner, and a documented photo record of every course of brick laid.

Liner Repair

Liner repair uses HeatShield Cerfractory sealant or a targeted stainless steel section to fix cracks and gaps in an otherwise functional flue. This is the right option when your camera scan shows a small defect but the surrounding tile is still solid. We apply the repair, cure it, and re-scan the flue the same day to verify the defect is closed. You get a receipt showing what was repaired, what remained, and what the re-scan showed.

Brands We Service for Chimney Liner & Rebuild

We install and warranty DuraFlex liners as our primary stainless steel system. Duarlflex is made in the U.S., carries a lifetime warranty on the liner body, and is UL listed for the specific fuels we size it for in Greenwich, including both wood and gas. We’ve installed hundreds of feet of DuraFlex and keep the full range of connector kits, top plates, and rain caps on the truck.

For resurfacing rather than full liner replacement, we use HeatShield Cerfractory material, which is a spray-on ceramic compound that repairs cracked clay tile joints and restores the flue’s ability to contain heat. It’s not a patch, it’s a structural coat rated for the same temperatures as the clay tile underneath. We also stock Copperfield caps and dampers, and we’ll service any existing system whether it’s Famco, Gelco, Olympia, or a brand we didn’t install. The same camera scan and written report applies regardless of what’s already in place.

Before

After

Signs You Need Chimney Liner & Rebuild Right Now

• Crumbling brick or mortar on the ground. If you find brick chips, sand, or mortar dust on the roof, the deck, or the ground around the foundation, your chimney is spalling. That means water has entered the masonry and is freezing and thawing. Spalling only accelerates. Once the face of a brick pops off, the softer interior erodes within a couple of seasons.
• White staining across the exterior brick. White efflorescence is dissolved salt being pushed out of the masonry by water moving through it. It tells you water is inside the system where it shouldn’t be. Once you see it, the water has been moving for months. The same water eventually reaches your liner joints.
• You can smell smoke or creosote in rooms adjacent to the fireplace. A liner with a cracked joint leaks flue gas into the cavity between the liner and the masonry. That smell in a bedroom or hallway is not coming from the fireplace opening, it’s coming through the internal voids. That’s an active fire and CO risk that one camera scan will confirm.
• Your chimney has no cap, or the cap is rusted through. Rain enters an uncapped flue directly, and the freeze-thaw cycle inside the flue is more damaging than anything happening on the exterior. A liner can be destroyed by years of direct rain exposure. And a missing cap lets animals fall in and block the flue entirely.
• The chimney is leaning or has visible cracks wider than a pencil. Structural movement means your chimney has lost the ability to hold itself together and the flue inside is likely cracked or fully separated at the joints. A leaning chimney is not going to stop leaning. It gets worse every freeze-thaw cycle, and in Greenwich’s climate, you get about 30 of those cycles each winter.

Our Chimney Liner & Rebuild Process, Step by Step

Here’s exactly what happens when you call us for liner or rebuild work in Greenwich.

1. 1
   Camera-scan inspection (Level 2). We lower a camera down the full length of the flue and record video the entire way. You watch the footage on our screen while we narrate what the camera is showing. This is the exact inspection standard in NFPA 211 Level 2 and it’s the only honest way to know whether you need a repair or not. Under Clause 4 of the Haven Standard, you receive the photos and footage before any repair recommendation is made.
2. 2
   Written scope and written price. After the scan, we write a line-item scope of work, a total price, and a warranty statement. This is a physical document you keep, not a verbal number you have to remember. It tells you exactly what we’re doing, what it costs, and how long we’re guaranteeing it. You don’t pay anything until after you’ve seen the written price and signed it.
3. 3
   Scheduled work with a named technician. You’re told exactly which background-checked, uniformed technician is assigned to the job, and you get a text when they’re en route. We don’t give a four-hour window and ask you to wait around. Greenwich homeowners tell us the single best part of the process is knowing who’s showing up and when.
4. 4
   The work itself. For a liner job, we’re in and out in one day. For a rebuild, we stage the site with tarps, run a clean masonry operation, and leave the site pass-through clean at the end of each day. Our crews break down into small teams so the disruption to your home is minimal.
5. 5
   Documented photo record and warranty. When the work is done, you receive a final photo record showing the completed liner, the rebuilt masonry, the new crown, and the new cap. You also get the written warranty for the materials and for our workmanship. Every job carries the 365-Day Done Right Promise: if it’s not done right, we make it right.

How Much Does Chimney Liner & Rebuild Cost in Greenwich?

Here’s what we see on actual jobs in Greenwich, Riverside, and Cos Cob.

Service	Typical Range	Timeline
Flexible stainless liner replacement	$3,200-$5,500	1 day
Rigid stainless liner replacement	$4,500-$6,800	1 day
HeatShield resurfacing repair	$2,800-$4,200	1 day
Partial rebuild (top 5-10 courses, crown, flashing)	$5,500-$8,500	2-3 days
Full chimney rebuild from roofline	$8,500-$12,500	3-7 days

What drives the price up is the same thing driving it up everywhere in Fairfield County: access. If your chimney is three stories up and requires a full scaffolding setup, that’s a couple thousand dollars of staging labor before a single brick is removed. If the flue is unusually short or the hearth area is tight, it counts as difficult access too. Material cost is actually the smallest variable. Steel liner is steel, whether it’s installed at a ranch in Old Greenwich or a four-story center-hall in Riverside.

The way to avoid overpaying is to make sure you’re not paying for work you don’t need. A contractor who tells you your liner needs replacement without a camera scan is guessing. We hand you the footage before we hand you a quote. And under Haven Standard Clause 1, the written price is delivered before anyone starts, so there’s no “tech already on site” pressure. We also offer a free second opinion on any competitor’s written quote. Bring us the number. If our camera scan says the work can wait, we’ll tell you that plainly and you’ll have the footage to prove it.
