GDM 5-Star Reviews

Strongly Recommended, they provided us with an excellent service and quality.


We hired GDM to design and build our sunroom late last year. The whole process went quite well even though there were several storms while the sunroom was under construction.
Mark and Rob did a great job.

– Rob Jones

thoroughly pleased with the results


GDM just helped me finish the home project of reglazing my four seasons sunroom. The entire project was executed flawlessly, and the crew displayed utmost professionalism. I am thoroughly pleased with the results.

– Mei Fan

The workers were friendly and helpful


When we decided to add a conservatory to our home, we chose one from Four Seasons which is affiliated with GDM Construction of San Jose. Robert, Mark and Vincent of GDM were very helpful and professional. Robert oversees everything and Mark and Vincent kept us in the loop with weekly progress reports while we waited for the building permit from the city. The workers were friendly and helpful, too.

High quality result by a first-rate team!


We did a Four Seasons Sunroom addition with GDM. They were great to work with throughout the process. Vince listened to our wishes very well, kept us informed weekly on each step of the process, and was great at resolving some electrical rework needed at the end. High quality result by a first-rate team!
