Replacement windows and door installation from an experienced, family-owned crew. New energy-efficient windows and a solid entry door make a home quieter, more comfortable, and cheaper to heat and cool through Southern Maryland's humid summers and cold winters. Free written estimates on every project.
Windows and doors are where a house leaks air, and in Southern Maryland that costs you in both seasons, cool air escaping through worn seals all summer, heat pouring out all winter. Gray & Sons Contracting replaces windows and installs doors for homeowners across Calvert, St. Mary's, and Charles County, handling the flashing and weather-sealing details that separate a lasting install from a drafty one.
Whether you're swapping out a few failed units or doing the whole house at once, we remove the old windows, flash and seal each opening, set the new unit level and square, and finish the trim so it looks original. Done right, replacement windows stop the drafts and condensation that come with old glass and instantly refresh how the house looks from the street.
Our climate, hot, humid summers and genuinely cold winters, makes efficiency worth paying for. We install double-pane, low-E, argon-filled windows that cut heat transfer both directions, ease the load on your HVAC, and knock down the drafts and window-sweat that plague single-pane homes near the water.
Your front door sets the tone for the whole house and is a real factor in security and comfort. We install steel, fiberglass, and solid entry doors, hang them so they seal tight and swing true, and weatherproof the threshold so wind-driven rain and cold air stay outside where they belong.
Sliding and French patio doors are a big span of glass, which means they're a big opportunity to gain, or lose, comfort. We install energy-efficient patio doors that glide smoothly, lock securely, and seal against drafts, connecting your living space to the deck or patio without turning that wall into an air leak.
A good storm door adds a layer of protection for your entry door, lets you open up for a breeze off the Bay on a nice day, and helps cut drafts in the cold months. We install storm doors that fit clean and latch solidly, so they earn their keep instead of rattling loose in a year.
Installed replacement windows in our area typically run between roughly $450 and $1,200 per window, and entry doors generally run from about $1,000 to $4,000 or more. Four things move those numbers most: the frame material, the size and style of the opening, the glass package you choose, and the quantity, doing the whole house at once usually lowers the per-window price. A premium door with sidelights and upgraded hardware sits at the top of the range; a straightforward steel replacement door at the bottom. Because every opening is a little different, we measure and price it in writing for free rather than guessing over the phone.
Old windows and doors rarely fail all at once, they just quietly cost you comfort and money every month. Replacing them is one of the upgrades homeowners tell us they wish they'd done sooner.
We install trusted, warranty-backed windows and doors from manufacturers like Andersen, Pella, ProVia, and Simonton, names chosen for real energy performance, durable frames, and hardware that keeps working. We match the product to your home and budget, from a value-minded vinyl replacement line to a premium clad or fiberglass unit, and we install to spec so the manufacturer's warranty genuinely stands behind you.
We install windows and doors throughout Calvert, St. Mary's, and Charles County, including Prince Frederick, Solomons, Lusby, Huntingtown, Dunkirk, Owings, St. Leonard, Leonardtown, California, Lexington Park, Hollywood, Waldorf, and La Plata. See our full service area.
Because we're a full home improvement company, a window or door project fits neatly into the bigger picture of your home. Replacing windows is the ideal time to also address the siding around them, since coordinating the two means the openings get flashed and sealed before the siding goes over, no gaps left for water. New exterior work often pairs naturally with your roof, and inside, our carpentry and trim crew finishes casings and jambs so every opening looks built-in, not bolted-on. One call, one crew, one standard of work.
