Washington DC Window Replacement & Custom Window Manufacturing

Why DC Homeowners Choose Thompson Creek

Thompson Creek has been serving Washington DC homeowners since 1980. We’re a Maryland manufacturer, not a national chain or a local reseller. Every window is custom-built to your home’s exact measurements at our Upper Marlboro facility, then installed and warranted by the same company that built it.

What sets us apart:

• Custom manufacturing: every window built to order for your specific opening, no stock sizes
• Factory-direct pricing: no middleman markups between manufacturer and homeowner
• One company accountability: we design it, build it, install it, and back it
• 50-Year No-Hassle Warranty: covers glass, frames, hardware, and labor, fully transferable

Built for DC’s Architecture

Washington DC has some of the most architecturally varied housing stock in the Mid-Atlantic. Federal row houses on Capitol Hill have settled over 150 years of use, creating non-standard openings that stock windows simply won’t fit. Victorian homes in Dupont Circle have ornate bay configurations that require custom manufacturing. Georgetown townhomes sit in one of the most closely reviewed historic districts on the East Coast.

Thompson Creek builds to exact measurements, which is why we’ve handled historic district work throughout DC for decades. For street-facing elevations subject to Historic Preservation Review Board (HPRB) guidelines, we offer simulated divided lites (SDL), period-appropriate grid patterns, and custom exterior profiles that satisfy review requirements while delivering modern thermal performance.

Window Styles We Install in Washington DC

• Double-hung: the standard choice for DC row houses and Federal-style homes. Both sashes tilt in for easy cleaning on multi-story properties.
• Casement: crank-operated with maximum ventilation and clean sight lines. Common in kitchens and main living areas.
• Bay and bow: custom-manufactured projection windows for Victorian dining rooms and sitting rooms throughout Dupont Circle, Mount Pleasant, and Columbia Heights.
• Sliding: practical for basement bedrooms, bathrooms, and mid-century homes in Spring Valley and AU Park.
• Picture and fixed: non-operable light maximizers, often combined with operating units in larger configurations.
• Specialty and geometric: custom shapes for dormers, stairwell transoms, and architectural features found throughout DC’s older neighborhoods.

Frequently Asked Questions

Do I need approval to replace windows in a DC historic district? It depends on the property and the elevation. Many DC neighborhoods fall under Historic Preservation Review Board (HPRB) jurisdiction, including Georgetown, Capitol Hill, Dupont Circle, and others. Street-facing window replacements on contributing properties typically require approval. Thompson Creek has experience navigating HPRB guidelines and handles the documentation when needed.

Can you match the original window profiles in my older DC home? Yes. Our Upper Marlboro facility builds to exact measurements and offers SDL configurations, period grid patterns, and custom exterior profiles. We regularly work with homeowners in historic districts to find solutions that satisfy review requirements without sacrificing performance.

How long does the process take? Most projects follow this timeline: a free in-home consultation, a written quote within 3-5 days, 3-4 weeks of production at our Maryland facility, and installation typically completed in one day for most DC row houses with 10-15 windows.

Is Thompson Creek local to Washington DC? Our manufacturing facility is in Upper Marlboro, MD, about 20 miles from downtown DC. We have been serving the District and surrounding communities since 1980.

What does the 50-Year No-Hassle Warranty cover? Glass, frames, hardware, and labor. The warranty is fully transferable to subsequent owners, which adds value when you sell. Because we manufacture, install, and service everything ourselves, there is no finger-pointing between a manufacturer and a separate installer if something needs attention.

Do you serve the DC suburbs as well? Yes. In addition to DC proper, we serve Northern Virginia (Arlington, Alexandria, Falls Church, Fairfax, McLean, Reston, and beyond) and suburban Maryland (Bethesda, Silver Spring, Rockville, Gaithersburg, and throughout the DMV). See our full service area list for details.
