Our Services

GMH Builders Inc. is a Sonoma based General Contractor focused on Commercial, Hospitality, Tenant Improvement, Healthcare, Multi-Family and Estate Residential construction.  We pride ourselves on providing a high level of service, maintaining budgets, schedules and quality to ensure client satisfaction . We excel at projects which are too complex for many small construction firms, yet are too small for larger firms to be both competitive and warrant their most talented staff.


General Contracting

GMH Builders provides general contracting services to exceptional clients in the North Bay. A majority of our work is negotiated and performed under a Guaranteed Maximum Price (GMP) project delivery method. This provides for a collaborative, open book process which allows projects to get started sooner, while minimizing the client's risk of cost overruns and project savings are returned to the client. 



We offer a full suite of pre-construction services including cost estimating services from conceptual budgeting through construction documentation. These services can include assistance with entitlement, constructability analysis, value engineering, cash flow analysis and scheduling.  From the outset, we focus on realistic budgeting, accurate documentation and ongoing review of costs to ensure clients make educated decisions towards their final plan.  


GMH Builders can handle your entire project, including planning, design, construction drawings, budgeting, and construction. The design-build approach provides a single source of accountability for your entire project, helps keep projects within budget and often results in faster overall project timeline. 


Ag Exempt

GMH can successfully take a project from client inception through completion of construction in a matter of months. This process can be handled completely in house and includes site suitability reviews, building programming, modeling/design, permitting and construction.
