& Window Company is a manufacturer, wholesale distributor, and installer of aluminum awnings, patio covers, carports,
screen room and wall systems, three-and four-season rooms and replacement windows. Thank you for visiting our web site. We
hope it will give you a good idea of what we strive to do at Glenlo Awning & Window Company.
Glenlo Awning & Window Company has been serving the greater St. Louis metropolitan
area since 1969. We are a family owned Missouri corporation registered in June of 1969.
We are a manufacturer and wholesale distributor of aluminum and fiberglass awnings, patio covers, screen rooms,
and three- and four-season patio enclosures. We also distribute three of the most complete and full-featured vinyl window
product lines available. We take great pride in not just selling these products, but also in their professional installation.
We’re very proud of our reputation for not only our quality installations, but for our excellent service as well.
With a hard working team, Glenlo Awning & Window Company has strived since 1969 to
maintain an excellent work ethic, high morals, and great service to all of our customers. In always setting the standard that
service during and after the sale is more important than the sale itself, we have been able to grow, prosper, and expand on
a referral basis and not on costly advertising programs. This allows us to keep costs in check and pass the savings, along
with quality, to our customers.
