"Jim did a terrific job on the floor. The project was complicated with lots of crazy angles and levels. Jim's expertise really shined for this project. He was very detailed oriented and a pleasure to have in my house. I forgot about a drain that a hole needed to be cut for. Jim drove over an hour back to my house to help me out and didn't even charge me for it. What a great professional! Please consider using him."

Energy Efficiency Auditing FAQs, answered by experts

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Yes, pros suggest units with high EER ratings for energy savings.

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