High Performance Home is a veteran owned, certified, fully licensed and insured home performance contractor.

High Performance Home has a proven track record of  13 years in business, along with Larry’s 40 plus years experience building, remodeling, and improving Maryland homes.  Unlike most other business’s, when you work with High Performance Home you’re dealing directly with Larry, the owner, who will be your contact from start to finish. And you’ll never get a lengthy sales pitch or high-pressure sales tactics from Larry. We get the job done right the first time and have many repeat and referred customers. High Performance Home is a participating contractor in the BGE and Potomac Edison Home Performance with Energy Star Programs so our customers can take advantage of the incredible rebates available.

We service homes throughout Howard County, Frederick County, northern Montgomery County, and Carroll County.
