Factory Certified Installers
Built for Annapolis homeowners with window installation and door replacement solutions backed by lifetime warranty coverage
Better Comfort
Lower Bills
Lasting Value
You see the condensation trapped between panes, feel the cold air creeping through the frames, and notice the rooms that never quite warm up. Old windows don’t just look tired—they cost you every month in wasted energy and constant discomfort.
The longer you wait, the worse it gets. Heating bills climb. Moisture leads to mold. And the home that should protect you starts feeling like a problem you can’t ignore.
Window Doctor specializes in custom manufactured window replacement for homes across Annapolis. We’ve built our reputation on precise measuring, factory certified installation, and a lifetime warranty that covers both product and labor. Every opening is measured to exact specifications so your new windows fit perfectly, with no gaps or forced adjustments.
Our installation teams handle the full project: removing old windows, addressing rotted wood during replacement, installing custom units, and sealing everything against air and water. We focus on energy efficient glass, vinyl frames built for the Chesapeake Bay climate, and proper flashing around every opening.
As a family-owned Maryland company, we show up on time, explain the process clearly, and stand behind our work. Your new windows add comfort, cut heating and cooling costs, and increase your home’s resale value.
Custom manufactured windows measured precisely for each opening, installed by factory certified technicians, and backed by a lifetime transferable warranty.
Durable vinyl frames resist moisture and rot, maintain efficiency over decades, and eliminate the maintenance cycle that wood demands.
Low-E glass and argon fill reduce heat transfer, cut seasonal utility bills, and stop the drafts that made your old windows uncomfortable.
Projecting window assemblies that add interior space, flood rooms with natural light, and become the architectural focal point from curb to living room.
Drafts disappear and rooms hold steady temperatures when every window fits its opening exactly, with no gaps or forced adjustments.
Custom fit windows and low-E glass cut heat loss in winter and block solar gain in summer, lowering monthly costs.
Factory certified installation means both product and labor are covered for life, and the warranty moves with your home if you sell.
Excellent experience from start to finish. Very professional company and staff, always available to help, very quick and easy to communicate with. Prices were reasonable and the team that did the install were fast and courteous. John Lippold, the rep from Window Doctor, was proactive about getting my questions and concerns answered and explained the entire process upfront. Highly recommend!

We had our windows replaced before selling our home, and it was one of the best decisions we made. They were able to repair the rotted wood around the windows, which increased the value of our home. We actually made money from the upgrade! The turnaround time was fast, and the whole process was smooth. I would definitely recommend them if you’re looking to replace your windows before selling.
