Recently while remodeling a house we went to Regency Windows. This is a place I'd highly recommend. Not only do they offer windows, siding, doors, and kitchen refacing, but they do it at great prices. If you go to their websit and fill out the form for an estimate you will receive coupons that will also save you money. They are trained and certified for the instilations and a lso a member of the Better Business Bureau.
