History
General Millwork Supply, Inc. (GMS,Inc.) is family owned & operated by Thomas & Wendy Duran, located in the heart of North County, San Marcos, California.  After moving to North County from their native state Connecticut, they opened their business in December of 1991 when small businesses were struggling to stay alive in a depressive economy.  The company was established during tough economic times at their one location and has weathered three recessionary periods; the last one being the toughest of the three.  They are “Celebrating 25 Years in Business” and attribute their success by planning and staying inside the lines on the guiding principles of the company’s core values.  By staying the course on a solid business plan through reinvesting in the company and focusing on the health of the company’s relationships with suppliers and its professional customers has enabled them to thrive.  These are some key reasons why General Millwork Supply has recently received these awards and honors that they proudly achieved over the past few years:    The 2010 “Dealer of the Year” in Overall Excellence and Leadership in the Professional Market by Window & Door Magazine; U-T San Diego – Voted one of “San Diego’s Best” Window and Door Company by the UT San Diego Reader’s Poll in 2012,2013 & Finalist 2014; Voted “Best of Houzz 2014 & 2015” in Service from the leading platform of home remodeling & design for customer satisfaction honors;  2014 Top Specialists – Listed as one of 2014 Top Specialists under $5 Million in Window & Door in May 2014 Magazine;   GMS, Inc. was the 5th largest Window & Door Dealer in sales for Andersen Windows, Inc.  in Southern California for 2013.

In addition to these honors, GMS, Inc. has received many good reviews on YELP & HOUZZ along with others from their customers over the years.  Through the use of social media:  the GMS Facebook page, Pinterest & Houzz sites provide helpful consumer information & ideas on products & services offered at GMS, Inc.  Photos of projects that our products were provided for show before & after pictures as well as whole house remodels.  This website has written Testimonials from some of the contractors & homeowner customers.

The internet has been instrumental helping new customers find us; whether it be Google, our supplier’s & manufacturer’s websites, referrals,  the social media sites GMS, Inc. has, the longevity of their URL, etc.; all contribute to help the company be found by their customers.
GMS, Inc. has many homeowner customers that you would expect to buy from you typically one time, but they have come back to them many years later to buy more windows and doors for their home & are happy to still find GMS, Inc. in the same location especially after one of the worst recessions ever.

It is very gratifying to Tom & Wendy that they made it through another recession since the building & remodeling industry was hit so hard for years, while many other competitors had to close their doors.  Sustaining their business is definitely something the owners, Tom and Wendy are thankful for!
