Who this page is for
Dayton has some of the oldest housing in the region. More than a third of homes in the City of Dayton were built before 1940, and in Oakwood the figure is about 55%. Many of those houses still have their original wood sashes, sometimes with old storm windows over them, sometimes painted shut.
The city currently has 13 locally designated historic districts, including Oregon, St. Anne's Hill, South Park, McPherson Town, Grafton Hill, Five Oaks, Old Dayton View, Wright-Dunbar and Wolf Creek. Nearby, Centerville has an Architectural Preservation District, and Oakwood is known for its well-preserved early 20th-century homes. If your house is in one of these places, window work comes with extra decisions.

Repair or replace?
Old-growth wood sashes are often more repairable than they look. Peeling paint, loose glazing putty, a broken sash cord and a rattle in the wind are all fixable. Replacement makes more sense when rot has reached the joints, when many pieces are missing, or when you need features the old window can't give.
| Lean toward repair if… | Lean toward replacement if… |
|---|---|
| Rot is limited to small areas of sill or rail | Rot runs through the sash joints or frame |
| Sashes are intact with original glass | Many sashes are missing, broken or replaced with mismatched units |
| The house is in a district where originals are valued | Earlier replacements already changed the look |
| You can add storm windows for winter | You need a bedroom egress opening |
Repair typically means stripping and reglazing, freeing painted-shut sashes, replacing sash cords, consolidating or patching small areas of rot, and adding weatherstripping. Ask each company for a line-item scope.
Storm windows: the low-cost partner to repair
A storm window adds a second layer of glass and an air space outside or inside the original sash. It cuts drafts and protects the old wood from weather. Interior storms are nearly invisible from the street, which helps in historic districts.
| Item | Typical range | Source |
|---|---|---|
| Storm windows | $100–$400 per unit + $67–$123 labor | Fixr, Aug 2025 |
| Wood window (unit), if replacing | $600–$2,000 | Fixr, Jan 2026 |
| Installation labor (replacement) | $150–$300 per standard window | Fixr, Jan 2026 |
| National average, per window | $800 (typical $450–$1,200) | Fixr, Jan 2026 |
Typical published ranges, not quotes (Modernize Aug 2026, Fixr Jan 2026, EcoWatch Jan 2025). Dayton installers' quotes vary.

Dayton's Certificate of Appropriateness
In a City of Dayton local historic district, exterior work such as windows needs a Certificate of Appropriateness (COA) before it starts. The city's zoning protects form, massing and fenestration, which is the arrangement of windows.
Minor COA
Replacement windows that match the existing design are a minor COA, handled by the city's Historic Preservation Officer. The city says routine requests often need little more than a phone call or email, and a minor COA can typically be processed the same day. There is no fee.
Major COA
Constructing or removing window or door openings, or changing their layout, is a major COA reviewed by the Landmark Commission.
Check the district type
Rules differ by zoning. HD-2 is the most restrictive, while HD-3 requires a COA only for demolition. Confirm which applies to your address.
Don't assume vinyl will be approved. Ask the Historic Preservation Officer what materials and profiles are acceptable before you order windows. In Centerville, the Board of Architectural Review has approved replacement windows on the condition that they follow the existing grid pattern. More detail is in historic district window replacement in Dayton.
Outside historic review: 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.
Lead paint on historic windows
Old window sashes and sills are one of the most common places to find lead paint. 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. Repair work that disturbs painted glazing or sashes usually falls under the same rule. Expect containment, a HEPA vacuum and cleaning verification. See lead-safe window replacement for pre-1978 homes.
Questions to ask
- Do you repair original sashes, or only replace?
- Have you worked on homes that needed a Dayton COA or a Centerville review?
- If replacing, will profiles, grille patterns and exterior trim match the originals?
- Will you prepare or help with the COA application?
- Are you an EPA Lead-Safe Certified Firm? Can I see the certificate and proof of insurance?
- What happens to the original sashes if they come out?
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. Related pages: wood and clad-wood windows and energy-efficient windows.
Historic Window Replacement & Repair FAQ
Can I replace my windows in a Dayton historic district?
Usually, with approval. Replacement windows that match the existing design need a minor Certificate of Appropriateness from the city's Historic Preservation Officer, with no fee. Changing the size or location of openings needs a major Certificate from the Landmark Commission. Ask before ordering.
Will Dayton approve vinyl windows in a historic district?
Don't assume so. The city reviews whether replacements match the existing design, and the answer depends on the district, the building and the product. Talk with the Historic Preservation Officer about acceptable materials and profiles before you sign a contract or order windows.
Is it cheaper to repair old wood windows than replace them?
Often, when the sashes are sound. Repair plus storm windows can cost less than new wood replacement units, which Fixr lists at about $600 to $2,000 each. Extensive rot changes the math. Get a line-item repair quote and a replacement quote to compare.
Do storm windows really help?
They add a second layer of glass and an air space, which reduces drafts and protects the original sash from weather. Interior storms are a good option where exterior changes face review. Fixr lists storm windows at about $100 to $400 per unit plus $67 to $123 labor.
