creating an optimal building experience

O’Hara & Gercke was founded in 2002 when Kevin O’Hara and James Gercke combined their many years of experience to create a company specializing in residential construction.

In 2022 the partnership expanded to include Zach Mitchell as a principal, further augmenting the firm’s management capabilities and construction experience.

O’Hara & Gercke is committed to creating a positive customer experience through effective communication, rigorous planning, transparency in budgeting and scheduling, attentive project management and outstanding execution in the field.  

We are typically involved in the very early stages of projects in order to provide technical input and budget guidance as options are evaluated and decisions are made. Once construction starts our job supervisors and craftsmen work closely with selected subcontractors to ensure a successful outcome.

SUSTAINABLE CONSTRUCTION

As the recipient of Efficiency VT’s “Best of the Best” award for “Energy Efficient New Construction” and a LEED Silver award from the U.S. Green Building Council, we encourage the use of sustainable construction technologies, materials and techniques. 

We have direct experience in natural, non-toxic and sustainable construction techniques including but not limited to  active and passive solar components, green roof design, advanced insulation strategies, fresh air heat and energy recovery solutions, energy efficient lighting, geothermal heating systems, wood fired masonry heaters, low and zero VOC coatings, and have worked with a variety of clients with unique environmental requirements to achieve cost effective solutions to their expressed concerns. We have built to Passive House standards, Net Zero Standards, and have constructed numerous Energy Star rated (5 star plus) homes in both Vermont and New Hampshire and are listed as an Energy Star Partner on Efficiency Vermont’s website.

We have the experience and resources to effectively incorporate emerging sustainable construction technologies into your project.
