Grabham Family

All members of the Grabham Family have worked for G Family Construction.


G Family Construction/Grabham Family Construction was founded over 30 years ago by our father James Grabham. During that period he practiced the art of carpentry and fine craftsmanship, having all three young Grabham boys (James, David, and Jon) serving as apprentices to him as he taught them integrity, work ethic, and the skills of carpentry. In 1998 James passed away and the brothers felt they needed additional work experience and to further their education in the field in order to carry on the company name. They spent the next 3 years working for high-end construction companies, refining their carpentry skills and gaining the experience to run their own jobs.

In 2001 David and Jon created G Family, Inc., ready to demonstrate the knowledge and ability that they had mastered in their many years in the field. Starting with decks & fences, they worked from one referral to the next. As time went on, G Family, Inc. grew by leaps and bounds. Integrity and a hunger for excellence were at the heart of their work and the skill of their hands. Always pushing their craft to the limits, they earned a reputation for high quality craftsmanship.


Continuing the legacy that James Grabham set forth over 30 years ago, the brothers have hand-selected apprentices of their own. All G Family employees demonstrate the same qualities that are at the foundation of the G Family Company. By spending one-on-one time training each employee, we are assured that the standard of quality we expect from them is achieved.

By working as a team we cover twice the amount of ground with hands-on site supervision. While most contractors only make it out to the job site to meet with the client, Jon & David oversee each project from start to finish. This enables them to find ways to make your project better and more cost effective. This also assures quality & safety control at the heart of the project, and builds a great working relationship with the client.


G Family employees get together regularly for BBQs, birthdays, and other personal events to build a sense of brotherhood throughout the company. Due to our high standards when selecting employees, we have an extremely low employee turnover rate.
