We bought a home in 2012, which had about 15 replacement windows installed in 2010 by Dunrite. We noticed in 2016 that a number of the panes were discolored/fogged, which indicated some sort of production issue with the low e glass (not due to Dunrite's initial installation). Dino worked with and for us with the manufacturer to have the defective sashes replaced under the manufacturer's warranty, which was transferable to us from the previous homeowner. Without any hassle or onerous paperwork requirements, Dino and the manufacturer's rep ordered and received the new sashes, which all fit perfectly. Jason, who performed the work to install the new sashes, arrived at our home at the appointed time and completed the work in a very efficient and workmanlike manner. The windows are now restored to a "like-new" appearance.
