Double Hung Windows

Double-hung windows are an increasingly popular choice for homeowners in the Quad Cities area due to the variety of design choices and enhanced comfort benefits. These windows are designed with modern features and technology that allow both sashes – the top and bottom – to open. This feature allows homeowners to experience increased ventilation in their home in the warmer months, without compromising on size or design that is common with other styles of windows on the market. At Mainstream Home Improvement, our double-hung windows are virtually maintenance-free and come with protective locks to ensure the security of your home and family when both sashes are not being used.

Why do I have condensation on my windows?

Excessive humidity levels in your home is what causes condensation, not your windows. Condensation is proof of excessive moisture in the air, which can actually be fixed with a dehumidifier or the cleaning of your HVAC units by a professional technician. For more information on condensation, please visit AAMA’s website.

How much can I save by switching out my old windows with new energy efficient windows?

This answer varies depending on several factors: the characteristics of your old and new windows, the size of your home, your property’s location, and more. ENERGY STAR® has put together calculated estimates of the energy you are bound to save when replacing a single-pane or double-pane clear glass window. Ask our team for more specifics on how much money you could be saving with our windows.

Why won’t my window sash stay up?

If your window sash won’t stay up, it may be due to the wrong size window being installed or the balance of your window is off. Unfortunately, this fix requires help form the professionals as the repair is different for every window style and manufacturer. Get in touch with our team if you’re having issues with your window sash.

What window warranties do you offer?

As a window dealer of MI Windows and Doors, our window replacement products are all covered under a Limited Lifetime Customer Assurance Warranty. This allows for homeowners to order replacement parts at no additional charge when their MI windows are broken or not operating properly. Some of our windows also come with a Glass Breakage Limited Warranty where new glass can be purchased at no additional cost if your window breaks.

How can I make the window installation process go as smoothly as possible?

To have your window installation process go as smoothly as possible, make sure the opening to your windows has been cleaned before our contractor gets there. Once your custom windows are installed, make sure there isn’t any more work to be done before using your windows. Lastly, take care of your caulk and trim to make sure your windows last as long as possible.
