EXCELLENT Based on 36 reviews hua tian2024-12-12Trustindex verifies that the original source of the review is Google. This company is wonderful! Every one is very kind and professional! The technician showed up on time and told us the window is actually in good shape. The small repair can done by myself. He told us where I can buy the products and how to do it in a right way. They are so honest and didn’t charge me anything for the inspection and the valuable expertise! Thank again sir and happy holidays!

Technician did not even charge as I didn’t require any material for the repair. I will definitely do business with this company in the future. LiveWell WithJoy2024-12-03Trustindex verifies that the original source of the review is Google. Rotten Window Repair is an amazing company. They did a great job of repairing a cracked window and saved me money. Another company I checked with before I found them wanted to replace the whole window, which would’ve cost more money. I highly recommend Rotten Window Repair for your new windows and repairs! Ricardo Bello Jr.2024-09-09Trustindex verifies that the original source of the review is Google. Tony and his crew are great!

I had a cracked window and wanted the glass replaced. Rotten Window Repair was reasonably priced. I called three other places. One wanted three times the amount. The owner was professional, personable and was able to install with much care.
