Real Stories, Lasting Impact

“Trim Tab took on a century-old home with a significant maintenance deficit and provided the design and project management services to refit it, including overcoming hidden defects that only became apparent once the project was underway. They succeeded in bringing the home up to 21st century air sealing and energy and GHG performance standards, combined with a full interior renovation that improves both the comfort and operating costs of the home.”
Terry JohnsonVice-President, Board of Directors Chatham Hope Non-Profit Inc.
We are excited about the partnership with Trim Tab for our pilot project. We believe that their expertise, professionalism, and dedication to our goals will be instrumental in achieving our desired outcomes. We highly recommend their services to any organization seeking to undertake similar retrofitting initiatives.
Craig CampbellBuilding Systems Supervisor, Indwell
“We engaged Trim Tab to perform a complete range of work including a hybrid heating system with a new high efficiency furnace and heat pump, an ERV, ductwork sealing and air sealing of the exterior of the home. The result achieved all our expectations. The home is completely comfortable on all levels, including the basement. The staff and contractors were professional and courteous at all times. They made the process very easy for us. A great result from a great team.”
