Depending on what you want to do, retrofitting your house could involve for example changing your heating system or installing solar power. This can be simple or quite complicated, possibly including hiring several contractors, and maybe a project manager too. You may be taking a ‘big bang’ approach or doing it in phases. Selecting competent, reliable contractors that you can trust and maintain a good relationship with is very important. This page is not a step-by-step approach to your retrofit but general advice about how to choose and work with contractors. Much of the advice on this page came from pooled experiences from the Energy Group members and friends.
