Chimney Relining in Greenwich, CT
Connecticut does more relining than most states, for one reason: when a household switches from oil to gas, the flue it inherits is far too large for the appliance now in it.

Leave the building and call from outside — that is an emergency services call, not a service call. A blocked or failed flue is one of the ways carbon monoxide reaches a living space, and headaches that clear when you leave the house point the same way. If you have had a chimney fire — a roaring sound, dense smoke, or debris on the roof — do not light another fire until the flue has been inspected.

Chimney Relining in Greenwich
Two things shape chimney work in Greenwich: the age of the building stock, and what the weather does to masonry that has been standing in it for decades. The chimney is rarely the thing that changed — what changed is usually what vents into it.
About 33% of homes in Greenwich were built before 1940 — old enough to have been built with radiators and no ductwork at all; 65% of them heat with natural gas, so oversized flues left behind by an earlier fuel are the recurring finding here. (US Census ACS 2022)
Why the flue is the wrong size after a conversion
An old oil boiler produces a large volume of hot flue gas, and the chimney was built to carry it. A modern gas appliance produces far less, and it produces it cooler. Put the second into the flue built for the first and the gases lose heat to all that masonry long before they reach the top.
Cool flue gas condenses. The condensate is acidic, it soaks into mortar joints and flue tile, and it works on them continuously through every heating season. Meanwhile the flue does not draw properly, which is a combustion problem as well as a masonry one.
A correctly sized stainless liner solves both at once. It gives the appliance the diameter it was designed to vent into, it keeps the gases hot enough to reach the top as gas rather than liquid, and it isolates the masonry from anything corrosive.
Sized from the appliance, not from the chimney
The diameter comes from the appliance manufacturer's venting tables, not from what will fit down the existing flue. That distinction matters — a liner that is merely smaller than the chimney is not the same as a liner that is correct for the boiler.
When insulation is required
An exterior chimney, a long run, or a flue on an unheated wall will cool the liner enough to condense even at the right diameter. A wrap or a pour insulation keeps the gases warm. It is not an upsell in those situations; it is what makes the installation work.
What relining involves
A flexible stainless liner is fed from the top of the chimney down to the appliance connection, secured with a top plate and clamp at the crown, and connected at the bottom with a tee. Where insulation is specified it is wrapped on before the liner goes in, or poured around it afterwards.
Most of the work happens on the roof. Where a chimney bends sharply, has an offset, or has a partial blockage of old tile, the job becomes considerably more involved and sometimes requires breaking into the chimney at the offset.
What makes one quote higher than another
Diameter, length, whether insulation is included, how many bends the chimney has, and whether the crown and top plate need rebuilding to seat the liner properly. Ask for those itemized rather than comparing headline figures.
Warranty is worth reading
Good stainless liner systems carry a lifetime warranty, but almost all of them make it conditional on professional installation and on the chimney being swept and inspected annually. Ask what the condition is, because an unregistered or unmaintained liner is frequently an uncovered one.

Chimney Relining in Greenwich — FAQs
I heat with oil in Greenwich — what does that mean for the flue?
Around 8% of homes here heat with oil, and oil soot is acidic. It attacks flue tile and the mortar between tiles from the inside, where a look from the roof will not find it. That is the case for a camera survey rather than a visual inspection. It also matters if you ever convert to gas: the flue will then be far too large for the new appliance and will need relining.
Nothing vents into our chimney any more. Does it still matter?
Less urgently, but yes. An uncapped disused flue collects rain, leaves and nesting for years with nobody noticing, and water sitting inside it damages the structure from within. If the chimney is genuinely finished with, removing it above the roofline and roofing over is a legitimate option. If anything at all still vents into it — a water heater in particular — then it matters as much as it ever did.
What chimney problem is most common around Greenwich?
Multi-flue stacks where each flue has a different appliance and a different requirement. That pattern is regional rather than universal — stamford, Norwalk, Greenwich, Westport, Darien and Danbury. It is worth knowing before you book, because it tells you what someone should be looking hardest at here.
How much does chimney work cost in Greenwich?
It depends entirely on what the chimney turns out to need, and the spread is wide. Sweeping, an inspection, a cap or a damper repair are the inexpensive end and are usually done in one visit. Relining, rebuilding above the roofline and full crown recasting are the expensive end. Nobody can quote it honestly over the phone, which is why the inspection comes first. The contractor you are introduced to sets their own prices and agrees them with you directly.
Do you cover all of Greenwich?
Yes — all 3 ZIP codes in Greenwich and the surrounding towns. Tell us where you are and we put you in touch with a company that covers it.
How quickly can someone get to me in Greenwich?
For a routine inspection or sweep, usually within a few days, and sooner outside the fall rush. Late spring through early fall is the quiet season and the easiest time to book. If you have had a chimney fire, or you can smell gas or have a carbon monoxide alarm sounding, that is not a scheduling question — leave the building and call emergency services from outside.
How long does a stainless liner last?
Good systems are warranted for the life of the home, conditional on professional installation and annual maintenance. The failure mode in practice is corrosion from an appliance it was not rated for, or from never being swept.
Can a liner be fitted if the chimney bends?
Usually. Flexible liner handles offsets that rigid pipe cannot. A severe offset may require opening the chimney at that point, which changes the cost, and a good surveyor will tell you before quoting rather than after starting.
