    Because of a forecasted nor'easter storm, we tried to reschedule our install date but were discouraged from doing so. We called the morning before the install date to reschedule and were told to wait until 7:00 the morning of the installation (10/28/15) to find out if the installation was to take place because of previous inaccurate weather forecasts. We did not get a call, so at 7:15 we called and left a voice mail message cancelling the installation. We were returning to our permanent residence, as this was a summer vacation home at the Jersey shore, and we did not want to deal with the flooding and high winds accompanying the storm. A return call came at 7:41 saying our message was received but the installers were already on their way. At 3:10 that afternoon we received a call notifying us of our new installation date for the upcoming weekend which was fine for us because the weather was sunny and warm. We were very pleased with the installation and the windows themselves (the condo seems warmer and quieter) but the confusion with the installation over the storm, could have been avoided. We gave 24 hours notice to reschedule so the installers did not have to start making a 2-hour drive in the driving rain. No window should be installed in those conditions.

    I needed a three-bay sliding door. Not only was it defined by the local home improvement store to be special, but they wanted to resize the wall of my house! Renewal by Anderson customizes the door size to fit the existing opening. Further, I wanted a large opening to allow furniture to be able to be moved into an out of the house; the third bay width was minimized to allow maximum door size. The door is beautiful. Also, its ability to keep heat in the house is extraordinary. I have a 20' by 20' family room that could bot be heated by a 35000 BTU propane fireplace beyond 66 degrees, at the highest flame setting. Now, 70 degrees is easy at the lowest flame setting! Great product and service, worth the money!

    The presentation of the product was so thorough and our representative was so knowledgeable of the product, all questions and concerns were answered. The gentlemen that installed our windows were so nice and personable, we welcomed them to have coffee with us. The installation went so smoothly and quickly you could tell the experience they had in this field of employment.The professionalism shown from all you were involved with our purchase and installation was outstanding.

    The windows are well insulated and calked. They put tarps down inside the house so that nothing was soiled and even vacuumed after they removed the tarps. They were very professional, very friendly and we wish we could give them more than 5 stars! We highly recommend Renewal by Anderson!

    The sales representative was very knowledgeable about the products. He was personable and professional. The installers were very friendly and professional. They demonstrated how to open, close and clean the windows. They were all outstanding from beginning to installation completion. Bravo!

    I wasn't sure what to expect when the representative told me about the windows and the quality. You just don't know if you are being sold a line or not. But I immediately noticed a difference after the installation was completed. The noise from outside was cut down significantly and the drafts were gone. I'm beyond pleased and considering replacing other windows in my home. I would strongly recommended RenewalbyAndersen windows.
