Certified DWM Professionals
The professionals listed below were awarded a ‘Certificate of Competency’ upon the completion of 6.5 hours of classroom instruction on the planning, design, and installation of DWM systems. It is important to remember, when choosing a contractor or product for your DWM systems, that DWM is a more intense process and is not suitable for all. Do your homework and find the expertise necessary to plan, design and install your project. Ask to see their certificate.
