Customer Reviews

Window World Charleston has done numerous window and door jobs for me and my family and will continue to do so. I commend Window World of the Lowcountry for their wonderful staff, and professional installers. You will definitely be doing more houses for me!
Wonderful and friendly workmanship. Your installer was on time and neat and very very friendly. Went directly to his work and did a wonderful job. Want him back when I have more windows installed!
The gentleman who measured my windows did a great job, and the installers and did a great job also. I had half of my windows replaced and because of the great experience I called to get the rest of my windows. If the rest of your staff is as excellent as those three gentlemen you have a great staff.
