Outdoor Kitchen Installation

If you love entertaining and grilling outdoors but hate standing alone at the helm while everyone else spends time in other areas of your home, installing an outdoor kitchen can bring the party outside. Outdoor kitchen installation offers a great return on investment and can help you to fully enjoy your home, inside and outside.

Additional Exterior Services

Beyond the services listed above, we also offer:


Sometimes, the space you currently have in your home just isn’t enough. High Performance Home is a skilled home addition contractor that can tackle everything from in-law suites to screened porches.

Screened Porches

As a screened porch contractor, we’re very experienced installing beautiful screened porches to help you enjoy the outside without bugs pestering you. Screened porches allow you to spend time outdoors without the sunlight bearing down overhead or raindrops falling on your e-reader.


Sunrooms (or three season/four season rooms) allow you to view the scenic outdoors of your home while still enjoying the comforts of home, like heating and cooling. These custom-designed rooms will extend your livable space for morning cups of coffee and afternoon snacks, all without worrying about the temperature or insects.

Family Room Additions

If you needed to convert just about every other room in your home to a bedroom to accommodate your growing family (or hobbies), a family room addition is a fantastic way to add a communal room to your home. Family room additions can offer well over a 60% return on investment, so you can feel good about the current and future state of your home’s value.

In-Law Suites

Multigenerational households are increasing throughout the country, and in-law suites are a great way to support your aging family members in your home. As an in-law suite contractor, we work with you to determine the best place to add on to your home, whether that means finishing the basement or building an entire addition. We’re familiar with ADA requirements and appropriate modifications for aging adults to ensure that everyone in your house can access every part of your home comfortably.

2nd Level Additions

A 2nd level addition should only be done by an experienced home remodeler, like High Performance Home. These major home additions can add a huge amount of space to your home to accommodate your family’s needs. We’ll work with you every step of the process to make sure that you end up with a second level you love that fits perfectly into your neighborhood.
