    Had replaced some windows with a different company a few years back. These were rated just as well and were a couple thousand dollars less per window. Out of the 3 estimates I scheduled, Window World was by far the cheapest, easiest, and less painful to get through. The contractor they sent initially to do the estimate was direct, honest, to the point, and willing to work within my budget and schedule. The others not so much. I will absolutely call them again when I replace the rest.

    From the sales experience through installation, I have been very satisfied. The windows themselves are wonderful. Customer service is 100% responsive and professional. I would recommend Window World (especially given competitor pricing!)

    We replaced all siding, soffit, and spouting. The job was completed in a very competent and timely fashion, and we are very pleased with the result. Now we have one of the nicest looking properties on the block! We are looking forward to replacing all windows as funds permit
