Energy Audit

Homeowners across Upstate New York depend on Nispen to conduct home energy audits. Our audits will save you money now and for years to come. A Nispen audit technician is trained and certified by the Building Performance Institute (BPI). Our audit technician will sit with you and listen to your concerns.

Insulation Services

Nispen's services include installing insulation in existing walls and attics. We can install cellulose insulation in existing walls from the outside of the home. This will leave no mess or dust in your home. Cellulose can also be installed in the attic thru hoses from our truck mounted blower system. You can be assured that our trained crews will clean up thoroughly before leaving the site.

Stop Air Flow From Your Home...

Most old and many new homes have leaky ductwork, which causes poor airflow.  This results in uncomfortable rooms and can expose people and pets to health hazards.  Beyond home comfort and health issues, porous ductwork can also cause your heater and air conditioner to age prematurely because the system cycles more frequently due to irregular and unnecessary airflow.

Lower Your Energy Bill Today...

Air sealing is probably the most important project that a homeowner should have done.  21% of the energy produced in the United States is burned in order to keep homes warm.  Many people consider this a figure that cannot be reduced.  The reality is it can be reduced one house at a time.  While some of the air leaks in your home are visible to the untrained eye (around doors and windows), much of the average home's air leakage takes place in areas you do not see.

Seal Your Home...

Sealing your home's "envelope" can greatly reduce energy loss in your home.  Indoor air can find many ways to flow out or in through gaps, cracks and holes in your basement, main floors and attic.  Many of these escape routes are built into your home by contractors and plumbers who drill, saw and hammer openings while placing studs, joists, rafters, beams, wires, air ducts, electrical outlets, water lines and waste pipes throughout your home.
