Better Building through Building Science

Comfortable. Durable. Efficient. Healthy. Safe. Valuable. We spend most of our time indoors so why settle for anything less than the best possible conditions in your building?

Kill Germs Inside

Clean indoor air is more important than ever. Now, using Active Pure Technology – the same system used by NASA – it is possible to rid the air and surfaces of bacteria, viruses and other contaminants.

Curious about transitioning to Fossil Fuel Free Heating?

Have you considered installing Heat Pumps or perhaps you have them already and are concerned about comfort? Air sealing and the right insulation will make your indoor environment comfortable and energy efficient using heat pumps engineered for cold climates.

Too Cold in the Winter & Too Hot in the Summer – INSIDE?

If you’re uncomfortable inside your building during extreme temperatures that is a sign that air from the outdoors is coming in. Stop the cycle of paying for heating and cooling air that leaves your home by air sealing. We’re here to help.

Every Decision Matters

Sometimes it is hard to make the best decision while considering building improvements due to conflicting advice from various contractors. We can help you understand the real options available to you and find the best solution.

Health & Safety First

Did you know that we breathe 35 lbs of air each day? In these times, it is vital to keep you and your family healthy & safe. We offer a complete diagnostic assessment of the Indoor Air Quality of your building. Then we provide you with recommendations to clean the indoor air.

Call A “House Doctor!”

Building Scientists are actually “House Doctors” because they diagnose virtually any problem in and around your building. Rather than contact heating and cooling professionals or costly pest control – call a “House Doctor” to diagnose and recommend a solution designed to last.
