Experienced & Trusted.

Northeast Air Sealing is a New Hampshire-based Energy Auditing and Home Performance company founded by Rich Burns in 2004. In their two decades serving the needs of New England buildings, Rich and his team have performed audits and directed energy efficiency and ventilation improvements on many local homes and businesses.

Energy Audits

A home energy audit is the most important first step towards a more comfortable home and increased saving on your home energy bills.


Inadequate insulation and air leakage are the largest causes of energy waste in most homes. A well insulated home can help reduce energy costs, make your house more comfortable and make walls, ceilings, and floors warmer in the winter and cooler in the summer.


We offer weatherization services for homes, multi-family buildings, and commercial buildings. Weatherizing your home is typically one of the best investments a homeowner or building owner can make for energy savings, energy bill savings, and reducing environmental impact.

Air Sealing

A massive amount of energy is wasted due to cracks, holes, and gaps in your house. Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings.

Spray Foam Insulation

Spray polyurethane foam (SPF) insulation is a state-of-the-art insulation product that dramatically increases a home’s thermal performance.

Indoor Air Quality

Indoor air quality problems are more common than we think and affect a large majority of homes in the United States.
