We started as a place where homeowners and do-it-your-selfers could purchase a wide variety of new and replacement windows. In addition, we carry entry doors, patio doors, and siding products without the hassle of high-pressure sales presentations. At DWS there is, and never has been, any pressure to buy and we give free estimates in writing.
