Less wasted heating and cooling
Air leaks and thin insulation can let conditioned air escape. Tightening those areas can help the system work less hard.
NYC insulation, air sealing & efficiency
Lower Energy Bills. Better Comfort.
Insulation, spray foam, and air sealing for NYC homes struggling with drafts, hot upstairs rooms, uneven temperatures, and rising utility costs.
A tighter, better insulated home can help reduce wasted heating and cooling. Some homeowners may also qualify for utility or state incentives, depending on the home, scope, and program rules.

Insulation + air sealing
Comfort, waste & incentives

Comfort problems
Small leaks can make the whole house feel off.
In NYC homes, comfort issues are often connected. A draft in one place, thin attic insulation, and gaps around older framing can make rooms feel completely different from each other.
PrimeSeal looks for where air is moving and where insulation is missing, then recommends practical work that fits the home.
Drafts around rooms, trim, attic hatches, and old openings
Hot upstairs rooms that never seem to settle down
Cold bedrooms, especially in older homes and top-floor spaces
Uneven temperatures from one room or floor to the next
High utility bills tied to air leaks and poor insulation
Older NYC homes leaking energy through gaps, attics, and walls
Our process
A clear path from comfort complaint to finished work.
The goal is not to sell every product. It is to understand where the home is losing comfort and recommend the work that fits.
Step 1
Inspect
We start with the rooms that feel wrong and look for the likely insulation and air leak paths.
Step 2
Recommend
You get a clear scope, plain explanation, and practical options before work begins.
Step 3
Install
The work is matched to the home, whether that means attic insulation, air sealing, or targeted spray foam.
Step 4
Clean up / follow up
We leave the work area in order and make sure the next steps are clear.
Rebate assistance
Help sorting through available incentives.
Some insulation and efficiency work may qualify for available programs that help offset part of the cost. The details depend on the home, utility, income, program eligibility, funding, and final scope.
Rebates, incentives, and savings are not guaranteed. Program rules, eligibility, documentation, timing, and funding can change.
Ask About EligibilityWhat may be covered
Eligible insulation, air sealing, and related efficiency work may be partly offset by available utility or state programs.
Who may qualify
Eligibility can depend on the home, utility, income, program funding, existing conditions, and the final scope of work.

Homeowner questions
Clear answers before you spend money.
Savings and incentives are worth asking about, but they should be explained carefully. The right answer depends on the house and the program.
How much can insulation save?
It depends on the home, existing insulation, air leaks, HVAC use, utility rates, and the work performed. The goal is to reduce wasted heating and cooling while improving comfort.
Can rebates cover part of the cost?
They may. Available programs can change, and eligibility can depend on income, utility, home type, scope, documentation, and timing.
Do I need to apply before the work starts?
Often, program steps and documentation need to be reviewed before work begins. PrimeSeal helps walk through what may be needed for available programs.
Does every home qualify?
No. Not every home, customer, or project qualifies. We can help review the likely options, but approvals and reimbursement are not guaranteed.
