Benefits for You and Your Home

For owners of vintage homes you might say weatherization is a must-have renovation. Vintage homes, while built with high quality and sustainable materials, can be especially drafty in the cold winter months. You can expect to have little to no insulation in houses built before 1940 unless they were later retrofitted to meet today’s building standards. Building science has come a long way and it’s now possible to bring vintage homes up to date.


While a decade ago the term “weatherization” was still quite ambiguous, CBA has been working with contractors for over a decade now, refining our robust program to help make vintage homes more energy efficient, affordable, valuable and comfortable - all at no cost to you. 

CBA's Energy Savers Program provides superior, high-performing air sealing and insulation, meaning you will experience the following benefits:


Energy Efficient Home
  • Your home uses less energy for heating or cooling to achieve and maintain a comfortable temperature.


Affordable Home
  • You can adjust your thermostat and save money on your utility costs! Past program recipients report an average of 50% gas bill savings and 30% electricity bill savings.


Comfortable Home
  • Your home is on average 45% less drafty, which should increase the comfort of your home significantly! 

Higher-Value Home
  • Your home is "Green Certified" and therefore recognized as being higher quality and worth more money.
