DOUBLE HUNG WINDOW EXPERTS
Double-hung vinyl windows have become the gold standard for homeowners seeking a perfect balance of energy efficiency, style, and low maintenance. For Washington DC residents, where summers are humid and winters can bite, this window style offers one of the smartest investments in both new construction and window replacement projects. Whether you're upgrading a drafty older home in Capitol Hill or planning energy upgrades in a Columbia Heights condo, double-hung vinyl windows deliver form and function in equal measure.
Unlike older wood frames or metal casements that warp, rot, or corrode, vinyl windows offer a durable, weather-resistant frame that doesn’t require painting or sealing. The “double-hung” design means both the top and bottom sashes can move up and down independently, offering superior airflow control. You can open the top sash to vent warm air while keeping the bottom closed for safety, ideal for homes with small children or pets. This feature also makes cleaning much easier: both sashes typically tilt inward, allowing you to clean the exterior panes from inside your home—no ladder required.
Beyond convenience and ease of use, energy savings are where double-hung vinyl windows really shine. Many models come with insulated glass, multi-chambered frames, and low-emissivity (Low-E) coatings that block UV rays while keeping conditioned air inside. For DC’s mixed climate, this translates into lower energy bills all year round. Combine that with noise reduction from double-pane construction and tightly sealed frames, and you've got windows that do more than just let light in, they protect your investment and lifestyle.
From a visual standpoint, today’s double-hung vinyl windows are sleek and customizable. They’re available in a wide range of finishes, grid patterns, and hardware choices to match any architectural style, from federal-style rowhomes in Georgetown to modern rebuilds in Navy Yard. They give you the crisp lines and modern finishes that DC’s discerning homeowners appreciate, without the upkeep headaches of traditional materials.
When it comes to repairs and replacement, the process must be handled by a skilled technician who understands the nuances of both the product and the structure of your home. Our team at DC Glass Doors & Window Repair begins by assessing the condition of your current windows. If you're experiencing problems like sticky operation, drafts, foggy panes, or excessive noise, chances are the seals have failed, the frame has warped, or the sashes no longer align correctly.
We remove the faulty windows with minimal disruption to your home’s structure or trim, making sure to preserve any existing woodwork where desired. Each replacement double-hung vinyl unit is custom-sized for a tight, secure fit. We seal it in place with weather-resistant materials that block air and moisture infiltration. Our team also ensures that the window is perfectly square and level to allow for smooth operation and long-term durability. Unlike DIY installs that risk voiding manufacturer warranties, our professional service includes full cleanup, haul-away of your old units, and a service guarantee. Call (202) 844-4421 NOW
For clients unsure whether to repair or replace, we offer transparent consultations. If your frames are still structurally sound but the sashes are worn or glass has failed, we can often replace just those components to save you time and money. If the window is beyond repair or you’re looking to upgrade energy performance, a full replacement is usually the better long-term value.
Many of our DC-area clients opt for our Energy Star–certified double-hung vinyl windows because they meet local code requirements and qualify for tax credits or rebates when part of an energy-efficiency upgrade. For commercial clients or landlords, they also enhance curb appeal and property value, an essential factor in Washington’s competitive real estate market.
