Fix the home first

Your home may be leaking more than you think.

Think of it like a bucket: if there are holes in it, there's little point pouring in more water. Your home works the same way — if heat is escaping through gaps, doors, windows, vents or inadequate insulation, every dollar you spend on heating, cooling or solar works harder than it should, and you still won't get the comfort you're after.

ThermalFix finds the leaks first, and gives you a plan specific to your home before you spend on anything bigger.

Up to 25%* less energy use in a properly sealed home

The Home Health Check — know what your home needs, before you spend a cent.

A short, free call. No inspection required to get started — just a few questions about your home and how it feels to live in.

By the end of the call, you'll know:
