Why double-hungs suit Charleston homes
Both sashes move, so you can open the top to let hot air out and the bottom to pull cooler air in. That simple trick is why tall double-hungs have been standard on Charleston single houses for two centuries.
Modern double-hungs keep that look and add tilt-in sashes for cleaning from inside, balances that hold the sash where you leave it, and insulated low-E glass.
Grille patterns that match your house
We match the existing lite pattern or choose one that suits the architecture:
- Six-over-six and nine-over-nine for Georgian and Federal homes
- Two-over-two for Victorian and late 1800s houses
- One-over-one for mid-century ranches and contemporary homes
- Prairie and craftsman patterns for bungalows
Frame options
- Vinyl: best value, low maintenance, wide color range
- Fiberglass or composite: slimmer frames, paintable, very stable in heat
- Wood-clad: real wood interior with an aluminum-clad exterior, ideal for historic and high-end homes
- Impact-rated: laminated glass for hurricane zones, see impact windows
Signs it is time to replace
- Fog or condensation between the glass panes
- Sashes that won't stay up or slam down
- Painted-shut or swollen sash that won't open
- Drafts, rattles or daylight around the sash
- Soft or rotted sills and bottom rails
Common questions
Double-hung or single-hung?
A single-hung only opens at the bottom and costs a little less. A double-hung opens top and bottom and both sashes tilt in for cleaning, which matters on second floors.
Can you match my historic window pattern?
Yes. We match lite counts, muntin width and sash proportions, including simulated divided lites with exterior bars.
How much does a double-hung replacement cost?
Most double-hung replacements in Charleston run $750 to $1,800 installed, depending on material, size and glass.
