Historic window restoration is not a single service with a single price. It is a range — and knowing where your project falls means understanding what you are actually paying for, and why. Here is the Baton Rouge breakdown.
Most homeowners calling Sashmo for the first time have the same question: how much does this cost? The honest answer is: it depends on what your windows need. Historic wood windows are not commodity products. They were built to be repaired, rebuilt, and restored — not landfilled. The pricing reflects that.
The Four Service Tiers
Restoration projects in Baton Rouge typically fall into one of four tiers. Each has a different scope, a different labor profile, and a different price range.
Tier 1: Assessment — $150–$225
Before any work begins, we do a window-by-window assessment. This is a structured walk-through where we document the condition of every sash, frame, and hardware element — and give you a written scope and estimate. You get a clear picture of what you are dealing with before you commit to anything. Some projects need only a light touch. Some have water damage that changes the whole scope. The assessment tells you which.
Tier 2: Mechanical Rehab — $300–$600 per window
If your sashes just need to work again — sash cord replacement, pulley service, weatherstrip, hardware adjustment — that is the lower end. This is the mechanical rehabilitation scope. It restores function without addressing paint failure, glazing condition, or wood integrity. For a typical Baton Rouge double-hung, this lands around $300–$600 per window depending on hardware complexity.
Tier 3: Full Historic Restoration — $1,300–$1,800 per window
This is what whole-house restoration projects in Baton Rouge end up needing. It covers everything in the basic tier, plus: channel rehabilitation, parting bead replacement, sash adjustment, weatherstrip throughout, and glazing repair, the part homeowners did on regular cycles, like painting the house, or repointing the brick, until they didn't. You are not just getting the window to work — you are getting it to perform. A properly restored sash in a tight channel with good weatherstrip will outperform a new vinyl window in most measurable ways.
Tier 4: Full Rebuild from Rough Opening — $3,500–$6,000+ per window
Some windows are too far gone to restore. Compounded damage including sill decay, running rail rot, and bottom rail damage that compromises structural integrity means rebuilding from the frame out. This is the premium tier. For the right project — a landmark district home, a contributing structure in a National Register district — this is almost always the right call. You are replacing like for like with old-growth cypress that will outlast anything installed today. The cost is real. So is the 100-year lifespan.
What Determines Your Project Tier?
Three things drive where your project falls:
Wood condition. Sills and rails under the glazing line take the most moisture exposure. If those are sound, you are in Tier 2–3. If the sills are soft and the running rails have moved, you could be approaching Tier 4.
Glazing condition. A window with intact but aging glazing compound is a simple repair. One with failed glazing and water intrusion behind the glass is a different project.
Historic district status. If your home is in a Baton Rouge Historic District or National Register property, the Historic Preservation Commission may require like-for-like materials. Old-growth cypress or clear pine sash stock is specified. This is not a premium for the sake of premium — it is a requirement that protects your property value and keeps you in compliance with the Certificate of Appropriateness process.
Old Growth Cypress: Why It Matters and Why It Costs More
New-old stock and milled old-growth cypress are not the same as construction-grade lumber. They are window-grade stock — vertical grain, defect-free, dimensionally stable — and they are increasingly scarce. When a restoration requires new sash stock, the material cost is higher. You are buying a material that was harvested before the 1940s and kiln-dried to standards that modern lumber does not consistently meet.
The upcharge is not arbitrary. It reflects the actual cost of acquiring and working with a material that functions differently from what you can buy at a lumber yard today. And for a window that will live in a historic opening for the next 80–100 years, it is almost always the right material choice.
Why Restoration Beats Replacement — Even on Cost
The comparison that most contractors use is price-per-window. Replacement windows look cheaper on that basis. But the comparison is incomplete. Here is what it misses:
- Vinyl windows last 20 years, tops, in Baton Rouge climate. Heat, humidity, and UV exposure accelerate the polymer breakdown. Wood windows, properly restored, last 80–120 years.
- Replacement destroys original materials. Once the old sash is removed and discarded, it is gone. There is no restoration path from a vinyl insert. You have made a permanent decision.
- Historic tax credits. For income-producing properties in certified historic districts, the Louisiana State Historic Preservation Tax Credit (25% state credit on eligible restoration costs) can meaningfully offset the restoration investment. Replacement is not eligible. Only like-for-like repair and restoration qualifies.
- Energy performance. A properly restored wood sash with fitted glass and quality weatherstrip performs comparably to a mid-range vinyl replacement in most thermal performance metrics. The difference is in longevity and character — not in the number.
Where to Start
If you have historic windows in Baton Rouge — double-hung, casement, fixed lite, transom — and you are wondering whether restoration is worth it, the answer is almost always yes. The only exception, however rare, is active structural decay in the frame that makes the opening unsalvageable, which is not visible from the outside.
Request an assessment and we will tell you exactly where your project falls. No obligation, no sales pressure — just a clear picture of what your windows need and what it costs.
