How Long Will It Take To Install Shutters in San Antonio? The whole plantation shutter process, from your starting consultation to installing the shutters, will take about four to six weeks on average. The process takes this long because we strive to build 100% custom shutters for your windows. Doing that requires us to take precise measurements, utilize sophisticated software to design them, assemble your custom shutters manually, and get them to your home for installation. Real wood shutters typically take longer than faux wood because of the added steps of staining and finishing the wood.It will take a little time, but it’s definitely worth the wait.
