Even a well-insulated home can lose significant conditioned air through gaps around plumbing lines, wiring penetrations, attic hatches, recessed lighting, and framing connections. Air sealing closes these accessible openings, helping keep the air you have paid to heat or cool inside your home.
As an air sealing contractor Long Island homeowners can use alongside insulation upgrades, we identify leakage points from the basement to the attic before sealing them with appropriate materials.

How it works
What Air Sealing Actually Does
Air sealing is for the purpose of sealing specific air leakage points, such as top plates, plumbing and wiring penetrations, attic hatches, recessed fixtures, and gaps around chimneys or duct chases. These points may not be noticed from within a completed room.
We use caulk, foam, weatherstripping, and other appropriate sealing materials depending on the size, location, and fire-safety requirements of each gap, then focus on the areas most likely to be driving drafts or energy loss.
Warning signs
Signs of Air Leakage in a Long Island Home
Air leakage doesn't always feel like a dramatic draft. These are common indicators worth having assessed.
Noticeable drafts near outlets, baseboards, or window trim
Difficulty maintaining a consistent temperature room to room
A home that feels drafty even with the heat running
Higher than expected heating or cooling bills
Dust buildup around baseboards or fixtures
Visible daylight around attic hatches or recessed lighting
Our process
Our Professional Air Sealing Process
Leak identification
We inspect accessible areas of the home, including the attic, basement, and around penetrations, to identify likely air-leakage points.
Sealing plan
We look at the gaps first for size and also most likely impact, as comfort and energy loss are our most important considerations.
Sealing work
With caulk, foam and a variety of other materials, appropriate, we seal accessible gaps, respecting the fire-safety clearances around chimneys and flues.
Review
We discuss what was sealed and note any additional insulation or ventilation improvements that may further support the home's performance.
Benefits
Benefits of Professional Air Sealing
Fewer Noticeable Drafts
Sealing accessible gaps can minimize the amount of drafty air that is usually seen around outlets, baseboards and around trim.
More Consistent Comfort
Less uncontrolled air movement can support more even temperatures between rooms and floors.
Reduced HVAC Runtime
When conditioned air stays inside longer, heating and cooling equipment may not need to work as hard to maintain a set temperature.
Better Insulation Performance
Air sealing can help insulation perform closer to its intended value by reducing airflow moving through or around it.

Frequently Asked Questions
-
Air sealing closes gaps and cracks that let air move through the building envelope, while insulation slows the transfer of heat through materials. They work together, and addressing air leakage first can help insulation perform as intended.
-
Common leakage points include attic hatches, recessed lighting, plumbing and wiring penetrations, top plates, and gaps around chimneys or duct chases. An assessment can identify the specific points in your home.
-
Yes, when done correctly. We maintain required clearances around chimneys, flues, and combustion appliances and use appropriate materials near those areas to avoid safety issues.
-
Air sealing can reduce uncontrolled airflow, which may lower HVAC runtime and energy use, but results depend on the home's existing insulation, equipment, and other conditions. It's often most effective when combined with insulation upgrades.
-
Most air-sealing projects can be completed in a single visit, though the exact time depends on the size of the home and the number of accessible leakage points identified.
