What a double-hung window is, and who it suits
A double-hung window has two sashes that both slide vertically in the frame. A single-hung looks the same, but only the bottom sash moves. Modern double-hung units have tilt-in sashes, so you can clean the outside glass from inside the room, a real help on a second floor.
This is the traditional shape on much of the region's older housing. The City of Dayton's median home was built in 1951, and Kettering's in 1961. On those houses, double-hung replacements keep the familiar look from the street and fit openings that were framed for this shape. They also suit owners who want to open the top sash for air without leaving the bottom open.

Signs your double-hung windows are done
- Sashes won't stay up, or slam down, because sash cords or spring balances have failed
- Windows are painted shut and won't open at all
- Fog or moisture sits between the panes of a sealed unit
- You feel a draft at the meeting rail where the two sashes overlap
- The bottom rail or sill is soft or crumbling
- Frost forms on the inside of the glass on cold mornings
Not every problem means replacement. A failed balance or a single foggy sealed unit can sometimes be fixed. See foggy window repair vs replace and signs you need new windows.
How installers replace a double-hung window
Methods vary by company and by the condition of the old frame.
Remove the old sashes
On an older wood window, stops and parting beads come out, the sashes are lifted out, and sash cords are cut. The empty weight pockets beside the frame are often insulated.
Set the new unit
For an insert, the new window slides into the existing frame and is shimmed level and plumb. Full-frame replacement removes the old jambs too; it costs more and takes longer per opening but exposes hidden rot.
Seal and trim
Low-expansion foam or backer rod and sealant fill the gap. Outside, trim is often wrapped in aluminum coil.
Test the sashes
Both sashes should slide, tilt and lock smoothly. Check this before final payment.
Dayton specifics
Lead paint. About 85% of City of Dayton homes and 85.5% of Kettering homes were built before 1980. Old double-hung sashes rub paint every time they move. If your home was built before 1978, federal law requires the installer to be an EPA Lead-Safe Certified Firm. Window replacement does not count as a minor repair under the EPA rule, so the small-job exemption does not apply.
Bedroom egress. A double-hung opens only about half its height, so the clear opening is smaller than the window. Ohio's residential code allows minor reductions in clear opening that come from using different materials in a replacement window. If you are changing the style or size of a bedroom window, ask the installer to check egress. Basements are covered on the egress windows page.
Historic districts. In Dayton's local districts, double-hung replacements that match the existing design need a minor Certificate of Appropriateness. See historic window replacement.
Permits. Same-size replacements usually don't need a building permit, but changing an opening or adding or altering an egress window does, and historic-district homes need a Certificate of Appropriateness. Your installer should confirm with your building department.

Pros, cons and when to pick something else
Pros: fits traditional houses; top-and-bottom ventilation; tilt-in cleaning; usually the lower-cost operating style.
Cons: the meeting rail and sliding seals let in more air than a casement's compression seal; only half the window opens; hard to reach over a sink or counter.
Choose a casement over a kitchen sink or where you want the tightest seal and a full opening. The trade-offs are laid out in casement vs double hung windows.
Questions to ask installers
- Is this a true double-hung or a single-hung?
- Do both sashes tilt in for cleaning?
- Will you insulate the old sash-weight pockets?
- What clear opening will the new bedroom windows have?
- Are you an EPA Lead-Safe Certified Firm, and can I see proof of insurance?
- What exactly does the written warranty cover, and who honors it?
Ohio has no statewide license for residential window installers, so ask each company for proof of insurance, EPA Lead-Safe Certified Firm status for pre-1978 homes, and any local registration your city requires. Dayton Window Replacement Pros does not verify licenses or insurance.
Double-Hung Windows FAQ
How much does it cost to replace a double-hung window?
Fixr's January 2026 data puts a double-hung window at about $300 to $1,000, plus around $150 to $300 labor for a standard size. EcoWatch puts Dayton's all-type average near $600 per window. Material, size, glass package and lead-safe work on older homes set where your quote lands.
What is the difference between single-hung and double-hung?
Both look alike. In a single-hung, only the bottom sash moves. In a double-hung, both sashes slide and usually tilt in for cleaning. Double-hung costs a bit more but lets you vent from the top and clean the outside glass from indoors.
Can I fix a double-hung window that won't stay open?
Often, yes. On older wood windows the sash cord may have broken; on newer units the spring balance has usually failed. Both can be repaired. If the frame is rotted or the seal has failed too, replacement may make more sense.
Are double-hung windows energy efficient?
They can be, with good low-E glass and a quality installation. Their sliding seals generally allow a little more air leakage than a casement, which presses its sash against the frame when closed. Compare the U-factor and air leakage ratings on each quote.
