Why Baltimore Homeowners Choose Thompson Creek

Thompson Creek has served the Baltimore area since 1980. We’re not a national chain or a local reseller. We’re a Maryland manufacturer. Every window is custom-built to your home’s exact measurements at our facility in Upper Marlboro, 30 miles from downtown Baltimore.

What that means for you:

• Custom manufacturing: no stock sizes, no off-the-shelf fits. Every window is built to order for your specific opening.
• Factory-direct pricing: no middleman markups between manufacturer and homeowner.
• One company accountability: we design it, build it, install it, and back it. One number to call for the life of the warranty.
• 50-Year No-Hassle Warranty: covers glass, frames, hardware, and labor. Fully transferable.

Built for Baltimore’s Architecture

Baltimore’s housing stock is unlike anywhere else in the Mid-Atlantic. Row houses in Federal Hill and Fells Point have been settling since the 1800s, which means non-standard openings that stock windows won’t fit. Victorian homes in Charles Village need grid patterns that match the original proportions. Waterfront properties in Canton and Locust Point face Chesapeake humidity and salt air year-round.

Thompson Creek’s Maryland factory builds to exact measurements, which is why we’ve been the go-to for Baltimore row house replacements for decades. We handle historic district requirements, including Commission of Architectural Review (CAR) guidelines for street-facing elevations, and offer simulated divided lites (SDL) and custom exterior colors to match your home’s character.

Window Styles We Install in Baltimore

• Double-hung: the most common style in Baltimore row houses. Both sashes tilt in for easy cleaning on multi-story homes.
• Casement: crank-operated, maximum ventilation, clean sight lines. Popular in kitchens and living rooms.
• Bay and bow: custom-manufactured projection windows for Victorian dining rooms and master suites throughout Mount Vernon and Roland Park.
• Sliding: practical for basements, bathrooms, and ranch-style homes in Baltimore County.
• Picture and fixed: non-operable light maximizers, often paired with operating windows in combination configurations.
• Specialty and geometric: custom shapes for dormers, stairwells, and architectural features common in Baltimore’s older stock.

Window Style	Estimated Range Per Window
Double-hung	$450 – $900
Casement	$500 – $950
Sliding	$400 – $800
Bay / Bow	$1,800 – $3,500

Frequently Asked Questions

Do I need a permit to replace windows in Baltimore? Like-for-like replacements typically don’t require permits in Baltimore City or Baltimore County. If you’re in a historic district (Federal Hill, Fells Point, Mount Vernon), exterior-facing work may require Commission of Architectural Review (CAR) approval. Thompson Creek handles the documentation when needed.

Can you match windows in Baltimore’s historic row houses? Yes. Our Upper Marlboro facility builds to exact measurements and offers grid configurations, SDL options, and custom exterior profiles to satisfy CAR requirements while delivering modern thermal performance.

How long does installation take? Most Baltimore homes with 10-15 windows are completed in a single day. Larger projects or historic district work may require two days. Production at our Maryland facility typically takes 3-4 weeks from order to install date.
