    What Are Sliding Patio Doors?

    Sliding doors provide a convenient yet attractive entry way to your backyard area. They feature two glass door panels that are easily opened and closed by sliding one panel behind the other along a horizontal track. The smooth operation allows you to effortlessly move between your indoor and outdoor spaces. Whether you choose double- or triple glazed insulated glass units, sliding patio doors allow lots of natural light in your home while maintaining a comfortable indoor environment.

    Sliding doors also come equipped with a sliding screen panel to let fresh air freely flow throughout your home. Since sliding doors do not open out or in on a hinge, they are the ideal option for homes and patio area with limited space. Furniture can be easily placed near the entryway without interfering with operation of the door at all.

The structural stability of aluminum allows for the assembly of bigger patio doors with the ability to create unique offset panels. In fact, aluminum Sliding Doors are the only ones that can support an asymmetric design. Although they are more expensive than PVC models (about 2.5 times), the quality and reliability of aluminum Sliding Doors is worth every penny.

    What Our Clients Say

    Window Mart completed my windows yesterday. A day ahead of schedule. They did all 6 of my basement windows in 3 days. Totally not expected and totally could've taken longer if they needed. They had to cut into concrete for 3 windows, including one driveway pad to make the window well. They did all 3 window wells for me. It's not very often you one-stop shop and get a company that does it all. They made it very painless and coordinated and did all the cutting and installation. I'm very happy with the service. Very happy with the results. I would definitely use them again, and probably will in the near future as I have a few properties to get work done and I know a few property managers I will refer.
    Ivan Ranyuk stopped by to give me quotes on a window and door. He is very polite and professional. Excited to get them installed here in Lethbridge!
    Vincent Zyp was very professional. informative and easy to talk to. He answered all out questions and gave us accurate quotes. Pleasure to deal with.
    Mikhail Mezentsev was the best to deal with. I would highly recommend when choosing a window company. AAAAA+++++
    Ivan was friendly, knowledgeable, and explained everything well. Pricing is great, too.
    We have had multiple dealings with this5-STAR company.Windows and a door were replaced on different occasions with both professionalism and courtesy. Quality materials and workmanship made our home weathertight and secure.Our dealings with agent Michael Romankov have been extremely pleasant. He goes above and beyond to help his clients. He even climbed a ladder on his own initiative and sealed up our drafty old windows, while we awaited replacement windows from Window Mart. No other competing agent offered to do that.Just recently (our cat is a rascal) Michael repaired our cat-damaged door screen FREE of charge. (Thank-you!)We have encountered only positives when dealing with Window Mart.Window Mart truly stands out in this modern day marketplace because of its high standards and friendly customer care.And since history has taught us (after getting many competing quotes) that Window Mart’s prices are fair and competitive, we will go right back to them for our future needs.

    How much do Modern Entry Doors cost?

    Prices for Modern Entry doors range based on a variety of factors, including size and customizations. Contact Window Mart today for an accurate estimate on replacement costs.

    Should I choose steel or fibreglass for my new Modern Doors?

    Steel and fibreglass both offer their own advantages when it comes to the construction of entry doors, including Modern Doors. Steel doors, for example, are a bit stronger and more durable compared to fibreglass. However, fibreglass doors are available in a wider range of colors and finishes and generally require less maintenance overall. It is best to speak with an exterior door expert to discuss your individual preferences. Window Mart is always happy to help sort through all the possible options, so you feel confident in your final entry door selection.

    How do I maintain privacy if I choose a Modern Door with glass?

    The beauty of glass inserts from Window Mart is that you are in complete control of their design. We offer a vast selection of frosted, textured, stained, and etched glass designs that can obscure the view through the glass and improve privacy levels. You can check out our Online Glass Inserts Catalogue any time to browse through our door glass collection.
