When choosing to replace your windows, it’s important to trust the experts. Double hung windows are some of the most versatile windows on the market with offering a unique advantage of having two operating sashes, which gives you the option to open the top, bottom or both sashes allowing ventilation throughout your home. A major benefit of having an operating top sash is that you can open the top sash to let the breeze in without disturbing the rest of the room with leaving everything in its place. Along with the added safety feature of keeping children and pets away from an open window, which is common with traditional single-hung windows that only open from the bottom. But prevents children or pets from damaging your window screens and creating an inconvenient cost.

Double-hung windows are the most preferred and common replacement windows by homeowners, as their sashes remain flush to the wall/window framing while the window is open, reducing the potential damage to your windows when open.
