How Are Shutters Installed on My Windows? An inappropriately installed window treatment can be difficult to open and can get damaged easily. We have a professional installation crew that comes to your home and installs your window treatment exactly, double checking that each one functions smoothly – and doesn’t get damaged when opened and closed. But before we start installing your shutters, we bring shutter samples to your home so we can custom build your window treatment together. Learn more about our free in-home consultation.
