I conduct energy audit tests for homes, whether they are colonial or brand new construction. I can recommend you various forms of weathersealant, thermal wrappings, and storm window techniques, saving you thousands in the form of long-term heat insulation tech-forward solutions.

"Everything went great, there were a couple changes that had to be made as the job progressed, we found out the old toilet had been leaking pretty badly, and there was a bunch of rotting floor boards.  Other than that they completed the job within our time frame, cleaned the house up at the end of each day very well, and really treated our home like it was theirs.  Everything was sealed up with plastic barriers so we wouldn't get dust throughout the house, I was very pleased about that.  We plan to have them back in the next year or two for the kitchen.

Energy Efficiency Auditing questions, answered by experts

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.
