How Are Shutters Installed on My Windows? An improperly installed window treatment can be tough to open and can get damaged easily. We have a professional installation crew that comes to your home and installs your window treatment precisely, double checking that each one moves smoothly – and doesn’t get damaged when opened and closed. But before we begin 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.
