Building Science for Better Homes Since 1997

One Community. Better Homes.

Our retrofits are in-house, grounded in building science, guided by real diagnostics, and carried out with care. Because of this, we remain intentional about the projects we take on. Thoughtful work requires focus, and every home deserves the level of attention our approach demands.

The Science Behind a More Comfortable Home

We have solved problems other contractors have been unable to resolve. At Project Probono, we utilize our years of building science knowledge to evaluate your home. We are dedicated to improving the health, performance and environmental impact of structures while also educating our clients.

Your home’s performance depends on how well its unique systems work together — from the building shell, to the heating and cooling system, to the ductwork. When one component underperforms, it can affect the comfort, health, and durability of the entire structure.

We have helped thousands of home and building owners in the Lehigh Valley area optimize their home’s performance for today’s needs and beyond.

We Begin With Understanding

Our energy audits evaluate much more than energy use. Comprehensive audits help to create a healthy, comfortable, and more durable home by identifying and preventing serious problems. We measure a home’s air tightness, ventilation, humidity, and moisture levels, in addition to identifying ways your home can be made more energy efficient. We look at your home with your goals in mind, while also checking common indoor air quality, comfort, and structural trouble spots.

COMMUNITY PROGRESS

Our Community Impact — June 2026

Measured impacts based on verified home performance, envelope sealing, duct sealing, and diagnostic testing.

In June 2026, Project Probono helped 22 families reduce approximately 31,108 CFM50, improve homes by 36.96 ACH50, and seal about 3,111 square inches of equivalent leakage area. That is comparable to closing about 78 average 20-inch-wide windows that were each left open 2 inches. Since 1997, Project Probono has helped more than 7,078 families improve comfort, efficiency, and home performance across the Lehigh Valley and surrounding Pennsylvania communities.
