I called Delaware Valley Aluminum to get an estimate to install three replacement windows in my basement. I have used this company before - they installed replacement windows in all of my other windows (26), installed siding and gutters/downspouts and did a FANTASTIC job. I had delayed the replacement of these windows because one of the windows had a dryer vent in it and I didn't know what to do as far as replacement of the window. Tommy Orsato came out to give me an estimate, and gave me a great suggestion (they actually sell a window designed with a built-in dryer vent!). Estimate was very reasonable, as usual. I ordered the windows, a few weeks later, scheduled the install and they were installed in a few hours - fantastic job. I like this company so much, that I have called them to see what else they do, as I would use them for everything - seriously!
