Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Cos Cob Homes Are Different

Cos Cob sits in the Mianus River watershed, and the housing stock tells the story of the town itself. Many chimneys serve homes built between 1920 and 1960, with original masonry that has survived decades of New England freeze-thaw cycles. The clay tile liners common in that era crack under repeated thermal stress, and once cracked, they allow heat and carbon monoxide to reach combustible framing.

The tree canopy matters too. Cos Cob’s older neighborhoods, particularly the streets running north from the Post Road toward the Merritt, carry heavy oak and maple coverage. Leaves and twigs drop into uncapped flues, and nesting squirrels and raccoons work their way into damp, shaded chimneys. A chimney that drafts fine in summer behaves differently once the firebox heats up and creosote inside the flue begins to expand.

Salt air from Long Island Sound accelerates spalling on brick exteriors, especially on chimneys with full north or east exposure. We see more crown deterioration and efflorescence here than in inland Fairfield County towns. The good news is that Cos Cob has no HOA restrictions on chimney work that we have encountered, and standard sweep and inspection jobs require no permit from the Town of Greenwich.

Our Main Cos Cob Services

The two jobs Cos Cob homeowners call about most are annual sweeps and the deeper inspections that follow a real estate transaction or a discolored smoke stain. Repairs run close behind.

Chimney Sweep in Cos Cob

A standard Chimney Sweep in Cos Cob removes creosote, soot, and debris from the flue using rotary brushes sized to the liner. We protect the hearth and surrounding flooring with drop cloths and run a HEPA-filtered vacuum throughout. Cos Cob homes with regular wood-burning fireplaces or older stoves tend to accumulate creosote faster than gas-only homes do. Clay tile liners in pre-1970 construction hold rough surfaces that catch soot more readily than smooth stainless liners. We recommend an annual sweep for wood burners and at least every other year for gas logs.

Chimney Inspection in Cos Cob

An Chimney Inspection in Cos Cob uses a camera system to document the flue interior, the smoke shelf, and the firebox. We provide a written report with photos, and we show you exactly what the camera sees before we recommend anything. In Cos Cob, inspections are most often requested before a home sale, after a chimney fire, or when a homeowner notices water staining on the ceiling near the chimney. The inspection report is yours to keep, and it notes whether the flue can wait or needs attention now.

Pricing for Chimney Company in Cos Cob, CT

Service Typical range in Cos Cob
Standard chimney sweep $189 – $329
Level 1 inspection $149 – $249
Level 2 inspection (camera) $289 – $389
Flue relining $2,500 – $6,000
Crown repair $400 – $1,200
Damper replacement $250 – $600
Chimney cap installation $200 – $450
Firebox repair $500 – $2,000

Two things push Cos Cob pricing upward. First, steep driveways and tight older lots make staging and ladder access more involved than on flat suburban streets. Second, salt-air spalling on older masonry sometimes means a crown repair is actually a crown rebuild. Every quote is delivered in writing before work begins, so the number you approve is the number on the invoice.
