Air Sealing & Insulation

Envinity has the comprehensive knowledge and experience to implement the principles of building science and improve the comfort and efficiency of your home.


Envinity offers air-sealing and insulation services for attics and crawlspaces, increasing the comfort of your home and helping your HVAC system operate more efficiently.

When it comes to energy efficiency, our first priority is making sure that your home is effectively air-sealed and insulated.  Preventing air leakage and heat loss is the easiest and most cost-effective way to conserve energy and optimize home performance.

The largest loss of energy is through air infiltration, which is the uncontrolled exchange of conditioned indoor air and ambient outdoor air.  By sealing gaps with expandable foam, caulk, and gaskets, we can reduce air infiltration by up to 60% – a significant savings in energy and cost.  We will test your house before and after we do the work, using state-of-the-art tools and techniques to quantify the level of energy savings achieved.


Insulating walls can be a necessary retrofit for older homes to increase home performance. These access holes will be patched so the wall looks as good as new.

After air-sealing, insulation is the next step in improving the energy efficiency of your home.  Most buildings in Pennsylvania are under-insulated, resulting in unnecessarily high energy bills.  Our team is skilled at finding the “cold spots”  and applying  insulation where needed – including walls, basements and attics.
In addition to retrofitting existing homes, we provide full insulation and air-sealing services for new construction.  We are typically on site for two to four days, depending on the size of the project, and when the job is done we’ll leave it clean and ready for the finish work to begin.
