Double-hung windows in Baltimore, Maryland
Two vertically sliding sashes; both the top and bottom sash open. For Baltimore's older housing stock (82.5% of homes predate 1980), double-hung window replacement is a common project — and in the ENERGY STAR North-Central zone, the number that matters most is a low U-factor (≤ 0.25) to keep heat in.
Short answer
Double-hung windows in Baltimore typically cost $730–$3,330 installed per opening. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand.

Is a Double-hung window right for a Baltimore home?
Both sashes slide vertically and typically tilt inward for cleaning.
Where it fits:
- Traditional and historic home styles
- Rooms facing walkways, porches, or patios (no outward projection)
- Easy cleaning from inside on upper floors
What to weigh:
- More potential air-leakage paths than hinged styles at equal quality
- Half the opening ventilates at any one time
Double-hung windows and Baltimore's climate
Baltimore sits in the ENERGY STAR North-Central zone (IECC zone 4A (mixed, moist), Baltimore City), where the priority is a low U-factor (≤ 0.25) to keep heat in.
Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the North-Central zone, prioritize a well-built unit and a low U-factor (≤ 0.25) to offset that.

What Double-hung windows cost in Baltimore
Double-hung window replacement in Baltimore runs $730–$3,330 installed. The low end is a mid-grade vinyl insert from a regional installer; the top is a premium frame, a full-frame installation, or a full-service national brand. National installed-cost ranges apply as a baseline, but Baltimore has real local drivers. Old masonry openings that are out of square, deteriorated wood sills, and lath-and-plaster interiors often push jobs toward custom-sized units and more labor than a modern tract home would need. In one of the city's 30-plus historic districts, CHAP review adds both time (approval typically precedes the building permit) and cost, since street-facing windows may need to replicate historic profiles and materials rather than use the cheapest stock vinyl. Mid-Atlantic labor rates sit near or modestly above national averages, and getting accurate quotes usually means having installers measure openings individually rather than pricing off a whole-house count.

Rebates & incentives in Maryland
The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.
Maryland runs IRA Home Energy Rebate programs through the Maryland Energy Administration; windows can be included in a modeled whole-home efficiency retrofit. Verify current program status before counting on funds. See our Baltimore guide for the full program list.
