About us
Window Doctor installs custom energy-efficient vinyl, fiberglass, and wood windows — including double-hung, casement, picture, 2-lite, and 3-lite sliders, bay, bow, and garden styles — precision-measured to 1/8 inch for a perfect fit. Our factory-trained installers use premium insulation and OSI Quad Max caulk for lasting, weather-tight performance in Maryland’s four-season climate. Most projects are completed within a single day. We also provide doors, siding, and gutter replacements. Choose from 21 beautiful window models — all custom-made for your home. Every estimate includes a one-year price quote, factory-direct pricing, and if you find a better written quote, we’ll match it and give you $200 for your troubles. Licensed and insured, MHIC #164611.
