How Are Shutters Installed on My Windows? An improperly 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 moves seamlessly – 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 design your window treatment together. Learn more about our free in-home consultation.
