Glenlo Awning & Window Company is a manufacturer, wholesale distributor, and installer of aluminum awnings, patio covers, carports, screen enclosures and wall systems, three-and four-season rooms and replacement windows. Glenlo Awning & Window Company has been serving the greater St. Louis metropolitan area since 1969. We have expanded to the St. Charles, MO. and surrounding area as well as the Kansas City-Blue Springs, MO. and surrounding area. We are a family owned Missouri corporation registered in June of 1969. 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.
