Energy Audits

I live in Waimea, and I get it…we take our homes for granted. We assume that everything is operating smoothly in our homes. While some home performance issues are obvious, others hide beneath the surface.

Blower door testing

Leaky houses are a problem. How much is your plumbing system allowed to leak? Not at all! They shouldn’t leak. How much leakage is allowed in your electrical system? Also none! So why should our houses be allowed to leak air?

Insulation

In Waimea, we’re no strangers to seasonal extremes. One winter it got down to 36 degrees at my house! That’s only four degrees above freezing!

Indoor air quality

Homeowners in Waimea & Hawaii will agree: Nothing’s more important than ensuring our families’ health and safety. We eat healthier and make regular visits to the doctor, but what about the environment in which we live? Many people don’t realize that their homes are characterized by poor indoor air quality, as the problem is not always obvious.

Building aloha on the big island

Your home is a complex system, and each element affects the others if something is changed…or goes wrong. Terrawatt takes a “whole home” approach to every job, no matter how large or small, and handles a wide range of home performance services and upgrades, including insulation, indoor air quality improvement, dehumidification, air sealing, dryer vent cleaning, building science consulting, and home energy audits.

Customer Reviews

Blake is fantastic — thoughtful, knowledgeable, and easy to communicate with. When our thirty-year-old boiler died, we contacted Blake for a broader look at our HVAC options going forward. He came over right away, and we had a therapeutic conversation about our needs and concerns, both now and in the … Read More

Werner Sun, Artist

After working with Blake for many months doing home energy audits, I can say he knows his stuff! He is thorough, has the client’s best interest in mind, is friendly, and when asked, can offer a teacher’s skill to explain the science behind what he sees at your place. He’s … Read More

Jeff Luoma

Blake is a motivated action-oriented wiz kid with just a touch of wise ass. (ed: we prefer “spunky.”) He clearly cares for our lived-in environment and has been a diligent carbon warrior for quite some time. He performs first-rate energy efficiency sleuthing and I’m proud to call him a fellow … Read More

Matt Redmond

Blake performed an energy audit for my in-laws as they evaluated whether to continue aging in their country home of 25 years. He could easily have sold them services they didn’t need. Instead, he pointed out immediate health-and-safety concerns that they could easily address on their own with a few … Read More

Sharon

I’ve brought Blake in as a consultant on difficult jobs. He continues to impress me with his breadth of knowledge, excellent communication skills, and passion for building science. He’s been an asset to my business, and I highly recommend his services.

Joel Frank, Contractor

I’ve known Blake for more than 30 years. I hate Blake. Blake is who I would be if I were smarter, better looking, and a hell of a lot more efficient. But I’m not and his silly business is too far away for me to hire him so I’m stuck … Read More

He’s your man when you want to plug all leaks and holes and upgrade to efficient utilities without breaking the bank.When our … Read More

Jackie

Blake is an excellent communicator. He is articulate, clear, present, and caring. He put together an outstanding team of contractors to replace my boiler, and he kept me informed and reassured throughout what was, for me, a very stressful time, given that I am a new homeowner and am spending … Read More

Barbara

We worked with Blake as a consultant, providing third party advice on the type of boiler we should install based on our budget, climate, and desire for long term reliability. He was generous and patient with his time, helping us to think through our options and chose the quote from … Read More

Elizabeth

The great room in the middle of our house has an 18-foot open-beam ceiling that has always collected more heat than expected, despite the excellent ventilation the room receives. Before consulting with Terrawatt, we installed an attic fan to pull heat from the upper great room into the attic, which … Read More
