Weatherized Long Island home with sealed and insulated envelope

Weatherization

Weatherize the whole envelope.
One scope, one crew, one number.

Weatherization is the package: sealing air leaks, insulating ceilings, floors, and walls, and upgrading windows where the math supports it. EnergiSense scopes it from the assessment and prices it as one line before any heating or solar work.

  • Air sealing + insulation
  • Window review
  • Comfort Home + EmPower+ paths
  • Sets up the heat pump bonus

Weatherization service

Tighten the shell.
Shrink everything after it.

Envelope

The whole shell, not one room

Attic, walls, basement, doors, and windows are scoped together so the house performs as one system.

Verified

Before-and-after blower door

The air leakage number after the work is the proof the weatherization did its job.

Next step

Sets up the heat pump

NYSERDA's bonus applies when the heat pump follows within 24 months, so weatherization is planned with the conversion in mind.

Weatherization decision

Scope the envelope.
Prove it with the blower door.

Weatherization is scoped from the assessment, priced as one line, and verified with a before-and-after leakage test. The heat pump and solar follow on the same plan.

01

Problem check

Drafty rooms, uneven temperatures, and high winter bills usually trace back to a leaky, under-insulated shell rather than the heating equipment. EnergiSense starts with the existing system, roof condition, utility account, and timeline so the recommendation fits the property.

02

Scope separation

Solar, roofing, storage, removal, and repair work are separated in the proposal so the homeowner can see what is urgent and what can wait.

03

Roof and electrical review

Roof age, attachment risk, inverter location, panel layout, shutoff rules, and access are checked before promising a simple install or repair.

04

Utility math

PSEG, Con Edison, or local utility details are reviewed against the actual bill instead of generic New York savings claims.

05

Manufacturer path

Scope, materials, ventilation, and moisture conditions are documented from the assessment. Windows are recommended only where the payback or a failed unit justifies replacement.

06

Next appointment

Weatherization fixes the shell first so every system that follows can be smaller. The intake asks for a quote path and preferred site-visit window so the page can turn ranking traffic into a real appointment.

Sequence

Seal, insulate, then decide on windows.

The order matters because each step changes the payback of the next. Air sealing is cheapest and fastest. Insulation comes second. Windows are last and only where the numbers support them.

  • Air seal the attic plane, rim joist, and major penetrations.
  • Insulate the attic floor, wall cavities, and basement or crawl space.
  • Weatherstrip doors and address failed windows.
  • Re-test with the blower door and record the improvement.

Programs

Comfort Home and EmPower+ in plain terms.

NYSERDA's Comfort Home program page lists $2,500 for the Good package, $3,000 for the Better package, and a $2,000 window add-on, plus a heat pump bonus within 24 months. EmPower+ supports income-eligible households with a no-cost assessment and upgrade help.

  • Comfort Home: $2,500 for attic and rim joist, $3,000 with walls and floors, $2,000 window add-on; participating contractor required and the whole package must be completed.
  • EmPower+: no-cost assessment and support for low- and moderate-income households.
  • PSEG Long Island: free home assessment for utility customers.
  • EnergiSense confirms which path applies to your address before quoting.

Comfort

Weatherization fixes the rooms that never feel right.

Cold bedrooms over the garage, hot second floors in July, and drafts along the baseboard are envelope problems. Bigger equipment masks them; weatherization removes them.

  • Even temperatures floor to floor once the attic plane is sealed.
  • Fewer drafts at outlets, baseboards, and doors.
  • Lower risk of ice dams when attic heat loss is controlled.
  • Quieter house with less outdoor noise through a sealed shell.

Roof and envelope together

The company that installs your roof also scopes the attic.

EnergiSense is a GAF Master Elite roofing contractor. Attic ventilation, roof condition, and insulation are reviewed in one visit so the weatherization scope does not conflict with the roof.

  • Soffit and ridge ventilation confirmed before insulation depth is added.
  • Roof age and condition reviewed so solar and weatherization are sequenced correctly.
  • Ice dam history addressed at the cause.
  • One proposal with roof, envelope, heat pump, solar, and battery as separate lines.

Weatherization FAQ

Questions before
the appointment.

What does weatherization include?

NYSERDA lists sealing air leaks, insulation upgrades for ceilings, floors, and walls, and high-performance windows as the weatherization measures. In practice on Long Island that means attic and rim joist air sealing, attic and wall insulation, basement or crawl space treatment, weatherstripping doors, and replacing windows only when they are failed or the payback supports it.

Is weatherization free in New York?

EmPower+ provides no-cost energy assessments and supports upgrades for low- and moderate-income households. Comfort Home pays $2,500 for a seal-and-insulate package covering the attic and rim joist, $3,000 when walls and floors are added, and $2,000 for an ENERGY STAR window add-on, through participating contractors and conditioned on completing the whole package. Neither is a blanket free program; eligibility is confirmed by address and household before EnergiSense quotes the net cost.

Should I replace my windows?

Only when they are failed, single-pane, or part of a renovation. Air sealing and attic insulation almost always return more per dollar than window replacement. The assessment's infrared scan shows whether the windows are actually a major loss for your house.

How does weatherization affect a heat pump later?

A weatherized house has a smaller heating load, so the heat pump can be sized smaller and run more efficiently. NYSERDA also notes a bonus incentive when a heat pump is installed within 24 months of completing seal-and-insulate work, which is why EnergiSense plans the two together.

Is the federal 25C energy efficiency tax credit still available?

The federal Energy Efficient Home Improvement Credit (25C) ended for property placed in service after December 31, 2025, so it does not apply to 2026 installs. State and utility programs are the incentives that still move the number on Long Island. Confirm your own tax position with a tax professional; EnergiSense models only the incentives it can verify for your address.

Do you do the weatherization work yourselves?

EnergiSense coordinates the weatherization scope under one proposal and one point of contact, alongside the roofing, electrical, solar, and battery work it performs directly. Contractor program status for NYSERDA incentives is confirmed on the proposal.
