Air Sealing
Top plates, wire and pipe penetrations, recessed lights, chases, and the attic hatch sealed before insulation goes down. Air sealing stops the stack-effect leakage that wastes energy and lets warm, moist air into the attic.

Rodent Exclusion And Proofing
Entry points sealed with copper mesh, hardware cloth, and sealant so the cleaned and reinsulated attic stays pest free. Coordinated with a licensed pest operator when an active infestation is present before the attic is closed.

Mold And Moisture Correction
Roof leaks, bath fan ducts venting into the attic, and condensation on the deck identified and corrected as part of the scope. Surface mold on sheathing treated so the new insulation is installed over a dry, sound deck.

Why Greenwich Attics Are Different

Greenwich runs from Long Island Sound waterfront to wooded backcountry ridges, and its attics vary just as widely. The backcountry estates north of the Merritt Parkway, set across Conyers Farm, Round Hill, and Banksville, are large early-1900s and pre-war homes with deep attics that were built before modern R-value standards and often measure R-19 or less. Waterfront Belle Haven, Riverside, Mead Point, and Old Greenwich homes take Long Island Sound salt air and humidity that degrade old attic insulation and feed deck condensation and mold. The heavy wooded canopy across the backcountry drives steady rodent pressure into these attics, leaving droppings in the insulation. Across all of these, the right sequence is the same: clean out the contamination, remove the failed insulation, air seal, and reinsulate to a code depth.
Greenwich sits in IECC Climate Zone 5, where the recommended attic level is R-49 to R-60. Bringing an under-insulated backcountry estate or an aging Old Greenwich colonial up to that target, paired with air sealing, is one of the highest-return energy upgrades on these homes, and it qualifies for Energize CT Home Energy Solutions rebates on the new insulation.

A note on accuracy: the federal Energy Efficient Home Improvement Credit (IRS Section 25C) for insulation ended December 31, 2025 and does not apply to projects completed in 2026. The programs above are state and utility incentives that cover newly installed attic insulation and air sealing. They do not cover removal, cleanup, or decontamination of old or contaminated insulation, which is billed separately.

Greenwich attic projects span a wide range because the town holds both accessible Old Greenwich and Cos Cob colonial attics and large, complex backcountry estate attics. As a general guide in this market, old insulation removal runs about $1 to $2 per square foot, and new blown-in insulation runs about $1.50 to $4.50 per square foot installed depending on the target depth. A full project that includes decontamination, removal, air sealing, and new insulation commonly lands between $4,000 and $14,000 depending on attic size, access, and contamination. Large backcountry estate attics around Round Hill with heavy rodent contamination drive the higher end. Every estimate is written and itemized, and Energize CT rebates reduce the new-insulation portion.
Greenwich sits in IECC Climate Zone 5, where the recommended attic insulation level is R-49 to R-60. Many pre-war backcountry estates and older Old Greenwich and Cos Cob colonials measure R-19 or less once the insulation has settled or been damaged. We measure the existing depth, then install new insulation to a uniform depth that reaches the R-49 to R-60 target, with depth markers set and photographed so the result is verifiable across the whole attic.
In most cases, yes. The wooded Greenwich backcountry around Conyers Farm and Round Hill takes steady rodent pressure, and insulation contaminated with droppings, urine, or bat guano holds pathogens, allergens, and odor that move into the living space through attic air. It cannot be cleaned in place. We remove the contaminated insulation under HEPA containment, sanitize and deodorize the deck, seal the roofline and soffit entry points, and then install new insulation.
Greenwich homeowners can apply Energize CT Home Energy Solutions rebates to new attic insulation and air sealing, typically up to $2.00 per square foot or 75 percent of cost, whichever is less, capped around $10,000 per home. A Home Energy Solutions assessment is required first. Income-eligible households can qualify for up to 100 percent coverage through HES-IE. The rebates apply to the new insulation and air sealing, not to removal or decontamination. Confirm current amounts on energizect.com before work begins.
No. The federal Energy Efficient Home Improvement Credit for insulation, IRS Section 25C, ended on December 31, 2025 and does not apply to projects completed in 2026. Homeowners who completed qualifying work by the end of 2025 may still claim it on their 2025 return. For 2026 Greenwich projects, the savings come from Energize CT Home Energy Solutions on the new insulation.
