Our Story

About Us

It all began fourteen years ago, with a personal experience. Our circa 1960 home had many of the problems commonly found in buildings - drafts, high fuel bills, constant maintenance and pests. We learned so much from our experience and, today, our home is comfortable as well as completely fossil fuel free.  We knew we had to help others learn from our experience and founded our Building Science based company.  The company is dedicated to finding cutting-edge solutions, providing great services and helping you achieve your goals - from planning to implementation. Hiring a Building Scientist during any of your building improvement projects can save you money by making sure that the repairs are accomplished efficiently and without any costly unforeseen consequences.

Building Comfort

Improving the comfort of buildings is more than assessing the quality and efficiency of your heating system. Insulation and air sealing play an important part in maintaining comfort, health & safety for all the building occupants for decades. If you're having comfort issues, consider a no obligation assessment today.




Diagnostic Testing

Do you experience any problems in your building? Perhaps your heating system runs frequently but doesn't feel very comfortable? Maybe you have a pest problem? You may find yourself painting the same part of the building exterior frequently.  In all of these instances, diagnostic testing can help you understand your building and finally solve the problem.

Indoor Air Quality

Viruses and bacteria travel through the air to live on indoor surfaces.  Reducing the amount of air movement in your home and installing a filtration system to kill viruses in the air and on surfaces will help you and your family stay healthy.

What we hear from our customers...

We’re thrilled about the fact that what seemed like a breezy cardboard box is now a cozy home. What a huge difference we’re feeling around here. I think your team did a great job, and I’m especially happy about what a great job they did of cleaning up after themselves. There was practically no sign that any work was being done around here. Aside from the wonderful results.
