When we decided to replace all the windows on the upper floor of our house we looked at all the options and spoke to several different window installers. We were interested in the alternative material Renewal By Andersen was marketing and booked a meeting with one of their sales reps. Roy came over and discussed various options and provided us with a thorough explanation of their windows and answered all our questions. Roy was involved from the start of the project to the end. Checking in with us during the measurement phase and install phase of the project. We were impressed with the professionalism of the whole installation crew. They showed up as scheduled and completed the job on time and cleaned up all the mess. They were also very attentive to any concerns we had during the installation and fixed any minor damage that was caused during the installation. Our project was completed last year and we waited to write a review to see how the windows faired through all the seasons. They have been great so far. No condensation or leakage issues through rain and snow. Overall it was a great job.
