I am one of the owners of Benchmark Consulting Services, LLC (“BCS”), I have been utilizing the expert services of Van Dijk & Associates, Inc. (“VDA”) for over 27 years now, and plan to continue to do so in the future. VDA has always provided excellent service to both my company BCS, and its clients. VDA has also provided expert services for my personal home, employees of BCS, the homes of many relatives and friends, all of which have been extremely pleased with VDA’s services and its personnel.

Over the 27 years that I have known and utilized VDA’s services they have proven to be trustworthy, loyal, honest, friendly and professional. VDA has great knowledge of all roofing and waterproofing materials, applications, repair recommendations and it also has access to manufactures literature. VDA also has superior knowledge of building codes and manufacturers recommendations for all roofing and waterproofing aspects of construction.

I would highly recommend using VDA as your roofing and/or waterproofing experts.

Van Dijk & Associates has provided waterproofing and building envelope consulting services to Red Oak Investments and its principals at multiple development sites, including at our current project Baker Block, a 240-unit residential development under construction in Costa Mesa, CA. We find the firm to be reliable, qualified, and easy to work with in their inspections and reviews of waterproofing-related work. We can confidently recommend the work of Nils Van Dijk and his team and would be happy to share more about our experience with the firm if helpful.
