“I really can’t say enough good things about Larry, Mike and their team! The execution of the work that was done was absolutely fantastic! The team arrived on time, kept me informed about what they’re doing, kept the work area clean, and when they completed the job, it was like they had not even been in my home.”
Jeff B., Mt. Airy

“These guys were extremely professional, polite, and thorough in the work they performed for us. Larry and Mike were able to answer all of my questions and address all of my concerns. Their high-quality work has helped us save on our electricity bill already and has dramatically improved the comfort level in our home this winter. Highly recommend High Performance Home!”

Greg L., Reisterstown

“I was impressed with the professionalism exhibited by Larry and Mike. Throughout the process, from discussing work that needed to be done and scheduling the work to be performed, I was pleased by the excellent customer service. The work was completed in the time indicated and I experienced a noticeable difference immediately. I strongly recommend High Performance Home to other home owners.”
Rhonda R., Glenwood

“They did an excellent job!”
Michael W., Darnestown

Joseph A., Clarksville

“Overall, we couldn’t be happier with High Performance Home LLC! We worked with the owner, Larry, during the planning and contracting phase. He was always available for questions and clarifications. We knew exactly what to expect on the date of the work. Larry is a true professional and was extremely easy to work with.
We chose this company based on its location, the strength of the Angie’s lists reviews (which are deservedly stellar!), and great first, second, and final impressions working with Larry and his team. They all take great pride in customer service and doing right by the customer. We would strongly recommend HPH to any one looking for a local company that stands by its great reputation by doing what’s right by their customers at a reasonable price.”

Peter S., New Market

“I have to compliment you on your son, Michael. A true pro, and super nice guy. Was very knowledgeable and friendly, and made my fiancé feel even more comfortable with what we were doing. I’d take a pro any day, but when they are also as nice as he is, it makes it even better. You should be very proud of the young man you helped raise.”
Matt B., Fulton
