I recently had all of my windows replaced by Dalco and I couldn’t be happier. I had several bids from other companies and I found their pricing to be comparable to the others with the quality of the windows being very high. I went into the process just thinking I would be replacing my windows with the exact same style. However my salesman, ***** provided some options for different layouts that really were a huge improvement. The crew installed everything in one day as promised and were very conscientious in how they worked and in the cleanup. Overall it was all a great experience and I am enjoying the efficiency of my new windows.

In December 2001 we hired Dalco to install siding and windows at our house. The professionalism of the salesman along with the expertise of the installers made this major project a pleasant experience. I fully expected that at some point I would have to battle for satisfaction however to my surprise that was not the case. Not only was the job completed to our satisfaction, the product has held up for 16 years. I recently found one of the windows had a piece of weather strip that had come loose. I called Dalco and they sent someone out to assess the situation and ultimately replace the weather strip at no cost. WOW that’s service and money well spent!
