Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Our Chimney Cleaning & Sweep Services in Old Greenwich
Level 1 Inspection
This is the annual checkup every Old Greenwich chimney needs, and the salt air here makes it non-negotiable. A Level 1 inspection covers the accessible portions of your chimney, flue, and firebox, plus a check of the cap and crown. In Old Greenwich, we’re specifically looking for corrosion on metal components and early spalling on masonry that most inland inspectors would never think to flag. Most standard sweeps include a Level 1 at no extra charge.
Level 2 Inspection
A Level 2 goes deeper and is required when you’re selling a home, changing fuel type (like adding a gas insert to a wood-burning fireplace), or after a chimney fire or major storm. Given how many Old Greenwich homes have converted wood fireplaces to gas inserts over the years, we run a lot of these. We scope the flue with a camera and give you the footage and a plain-English verdict, every time, no exceptions. If you’re anywhere near Greenwich Point and haven’t had a Level 2 done since buying your home, it’s worth having one before the next burning season.
Creosote Removal
Creosote is the flammable residue wood fires leave behind, and it builds up in stages. First-degree creosote is a brush job. Third-degree is a glaze and needs mechanical removal or chemical treatment. Old Greenwich homes with original clay tile liners and heavy wood-burning fireplaces tend to accumulate creosote faster in the smoke chamber because the older flues draft less efficiently than modern insulated liners. We’ll show you what came out and what it means.
Soot Removal
Soot is different from creosote. It’s softer, dustier, and more common in fireplaces used occasionally or with gas logs. It still coats the flue walls and reduces draft, and in a coastal town like Old Greenwich, soot mixed with humid salt air can cake onto the flue surface and become harder to remove the longer it sits. An annual sweep handles it before it becomes a job requiring rotary cleaning.

Trusted Brands We Service in Old Greenwich
We install and work with products from HeatShield and Copperfield most often on Old Greenwich chimneys, along with Gelco and Olympia Chimney products for specific repair and liner work. HeatShield’s cerfractory sealant is something we’ve used on older flues near the water, where tile cracking from moisture and freeze-thaw cycles shows up early. We carry most common repair parts on the truck, which means less waiting around when your cap or damper needs replacing.
Common Chimney Cleaning & Sweep Problems We See in Old Greenwich Homes
- Corroded galvanized chimney caps. Salt air off Long Island Sound chews through galvanized steel in three to five years. Once a cap rusts through, rain goes straight down the flue, rust-stains the brick, and starts soaking the interior masonry. We replace them with stainless steel Copperfield caps that shrug off the coastal environment.
- Spalling brick faces and cracked crowns. Maritime humidity pushes moisture into the brick. Winter freezes expand that moisture. Hairline cracks open up every season, and once water gets behind the brick face, spalling follows. Homes on Shore Road and the streets closest to the water see this worst.
- Original unlined or single-wythe flues passing inspection after light use, then failing fast. A lot of these 1920s and 1930s chimneys sat mostly unused for years. When new owners start using the fireplace regularly or add a gas insert, the old tile liner can’t take the thermal cycling. We see flue tile cracks appear within two or three seasons of renewed use.
- Draft problems in pre-war chimneys with gas inserts. Original flues were sized for wood. A gas insert produces cooler, wetter exhaust, which doesn’t draft the same way in an oversized flue. That means condensation, soot buildup, and sometimes carbon monoxide backdrafting. A proper liner sized for gas fixes the physics.

A standard chimney sweep with a Level 1 inspection in Old Greenwich runs $189 to $329 depending on the number of flues and the amount of buildup.

FAQs - Chimney Cleaning & Sweep in Old Greenwich
Every year, no exceptions. The salt air and coastal humidity off Long Island Sound accelerate corrosion and mortar erosion at a rate that makes an annual Level 1 inspection a structural necessity, not a courtesy upsell. In inland Greenwich neighborhoods you might stretch it to eighteen months. Not here. Call (475) 375-2748 and get on the calendar before burning season.
Salt. The air directly off Long Island Sound carries airborne salt particles that deposit on masonry and metal surfaces year-round. Combined with maritime humidity and hard winter freezes, that salt environment corrodes galvanized caps in three to five years and opens hairline crown cracks every winter. Cos Cob and Glenville sit far enough inland that they don’t get this constant salt exposure. If your cap is galvanized and more than four years old, you should have it checked.
Get a Level 2 camera inspection before your next fire. Unlined and single-wythe flues were common when these 80 to 100-year-old waterfront homes were built, and they can pass inspection for decades under light use. But once usage picks up, or a gas insert changes the thermal profile, cracking shows up fast. If we find damage, we’ll show you the footage and walk you through what actually needs doing. Some flues can be lined with HeatShield. Some need a full stainless liner. You’ll see the evidence yourself before any recommendation is made.
Yes, but not the way you’d think. Gas inserts don’t produce creosote, but they do produce acidic condensation and soot that coats the original clay tile liner. The bigger issue is sizing: a flue built for a wood fire drafts too much for a gas unit, which means cooler exhaust, more condensation, and faster liner deterioration. If you switched to gas, you still need an annual inspection, and you may need a properly sized liner.
Look for rust staining running down from the cap, white chalky deposits (efflorescence) on the brick face, flaking brick corners, and hairline cracks in the crown. Any of these means water is getting somewhere it shouldn’t. Walk around your house with a pair of binoculars, or just call us. We’ll take a look and tell you what’s what.

Salt Air, Your Chimney, and What Actually Matters
Old Greenwich sits directly on Long Island Sound, and that’s not just a nice view. It’s a salt-laden microclimate that changes how fast your chimney’s exterior components break down. Galvanized chimney caps last maybe three to five years here before they rust through. Crowns develop hairline openings every winter from the freeze-thaw cycle, and the salt in the air accelerates the corrosion of flashing and dampers at a rate measurably faster than what we see in Cos Cob or Glenville. This isn’t theoretical. On Shore Road near Greenwich Point, we swept a 1938 Colonial with its original clay tile flue liner. We found a corroded galvanized cap and open mortar joints at the crown from salt air, plus first-degree creosote in the smoke chamber. We replaced the cap with a stainless steel Copperfield model and repointed the crown before freeze-thaw could worsen the spalling. That’s what coastal exposure does, and it’s why an annual inspection in Old Greenwich is not an upsell. It’s what keeps a $600 repair from becoming a $6,000 rebuild.
If your chimney hasn’t been looked at in the last year, call (475) 375-2748. Wendell or one of his crew will come out, do the job right, and back it with the 90-Day Done Right Promise in writing. Your flue doesn’t care how the fire looks. It cares how it breathes.
