For homeowners & homebuyers

Your house, healthier and cheaper to run.

Whether you've lived in your home for twenty years or you're about to buy one, the question is the same: what should this house become, and where do I start? GreenStar gives you the answer as a clear, published checklist, plus an independent professional to verify the work when you want it.

Sound familiar?

You want the house safer and cheaper to run, but every contractor has a different opinion about what matters first.

You're buying a home, and the inspection tells you what's broken, not what the house could become.

You've paid for "green" upgrades before and have no way to know if they actually worked.

You keep putting it off because there's no plan, just a pile of articles and quotes.

  3. 3

    Verify it when it matters

    A GreenHome Inspector assesses the house against the standard and certifies the result, so an outside expert signs off instead of your contractor, and the value shows at resale.
