Front Range Lumber Company is a Milgard Certified Dealer.

Milgard is one of the largest window manufacturers in the United States. Milgard offers local service, an excellent warranty that includes condensation coverage, short lead times (including special orders), a range of products, plus a wide range of glazing options, hardware, and more.

Front Range Lumber Company has been family-owned and operated since 1965, and we have a reputation for service and product knowledge. Our sales people are not on commission, so you’ll enjoy an “old-fashioned,” home-town buying experience. Deliveries are made quickly by our own fleet of trucks, to help keep your job on schedule.

We do not install the products we sell, allowing you the freedom to install them yourself, or use a trusted installer or contractor that you choose to fit your budget.

Other Reasons To Buy Milgard Windows and Doors

  • Milgard puts their logo and other identification on their products. Even if you forget the brand you bought and lost your receipt, the windows are identifiable. Notice how many companies do not brand their product. Are they worried about their window performance in the future?
  • Milgard is a well known, national brand with the same name for over 45 years. Other brands have changed their name to leave behind problems.
  • Low-E is standard in Milgard windows. While argon is available at a small upcharge, we do not push it – or any other features – that some consider “gimmicks.”
  • All products are made custom for you. This means that replacement sizes are not a problem. Windows are made in 1/8” increments, at no upcharge for special sizes. And your windows fit much more exactly.
  • Two lines of vinyl windows are available. The price difference is about 40%. We will be happy to show the features of both lines. Both have the same Milgard warranty.
  • Milgard is a national company. We are lucky to have a Milgard plant right here in Aurora. This expedites window lead times as well as service if necessary. Milgard brand products are common throughout the Denver metro area. Many homeowners and contractors are familiar with the brand. Milgard has been used in many Parade of Home locations over the past few years.
  • Front Range Lumber sells only the Milgard brand, as they are the BEST brand available to satisfy the needs of our customers.
