Who We Are

We are mission driven

Trim Tab’s mission is to renew housing and inspire better living.

Housing is basic to our survival. Quality housing does more  – it nurtures us. Fresher air, brighter spaces, even temperatures and affordability are the hallmarks of quality housing and support better quality of life. 

We deliver turnkey
energy retrofits

Energy retrofits are building improvements that change the way we use energy and improve quality of life. This includes air sealing and upgrades to lighting, controls, and the HVAC system. Energy retrofits are the secret sauce of a high-quality renovation because they strongly effect the things we want from their indoor environment – comfort, fresh air and affordability.

Trim Tab got started to address the need for a contractor who specializes in energy retrofits. Energy retrofits are complicated and timing matters. 

To ensure the work is done right and at the right time, Trim Tab streamlines the execution of retrofits through its unique business model as an energy contractor, which integrates testing and measurement with the capabilities of a multi-trade contractor.
