Historic Window Restoration

Preserving the Past Without Sacrificing Performance
In historic neighborhoods from San Francisco’s Nob Hill to the Victorian-lined streets of Alameda, original windows are more than architectural features—they’re part of the building’s identity. But aging wood sashes, single-pane glass, and outdated hardware often lead to drafts, leaks, and energy loss.

That’s why AFR Windows specializes in historic window restoration that preserves the integrity of your building’s design while enhancing performance, safety, and comfort. We help property owners, preservationists, and architects find the balance between history and modern function.

The Problem: Aging Historic Windows Cause More Than Drafts
Historic windows may have stood for 50 to 100 years—but time, weather, and poor repairs take a toll. Left unaddressed, you may face:

• Wood rot, paint failure, and stuck or broken sashes

• Air leaks and poor thermal insulation

• Single-pane glass vulnerable to breakage

• Code compliance issues for egress, glazing, or safety

• Pressure from tenants or inspectors to replace instead of repair

But full replacement isn’t always the right answer—especially in registered historic districts or when aesthetics and value are tied to original craftsmanship.

The Solution: Authentic Restoration With Today’s Performance Standards
At AFR Windows, we believe in honoring original architecture. Our historic window restoration services are tailored to maintain your building’s visual integrity while improving function and efficiency.

We offer:

• Restoration and repair of original wood, steel, or aluminum window frames

• Reglazing with insulated or laminated glass options that meet code

• Weatherstripping upgrades to reduce drafts and improve thermal performance

• Sash cord, weight, and pulley system repairs or replacements

• Full stripping, sanding, and repainting to match original color schemes

• Custom millwork replication for rotted or missing parts

We restore what can be saved and replicate what can’t—always with respect for your building’s history and community guidelines.

Why Restoration Matters More Than You Think
Historic window restoration is more than patchwork—it’s an investment in your property’s future. Compared to full replacement, restoration:

✅ Preserves the architectural authenticity of your building
✅ Often qualifies for historic tax credits or grant funding
✅ Is environmentally responsible—reduces material waste
✅ Enhances energy efficiency with modern glazing and seals
✅ Increases property value while maintaining visual continuity
✅ Keeps you compliant in regulated or protected districts

Plus, many older windows were built from old-growth wood that’s more durable than modern materials—making restoration the smarter long-term option.

A Tailored Process Rooted in Craftsmanship
Every historic window project is different. That’s why our team follows a detailed restoration process:

1. Assessment – Evaluate current condition, identify damage, and document profiles

2. Preservation Plan – Propose treatments aligned with local and national standards

3. Careful Removal – When needed, we remove sashes or frames without damaging surrounding trim

4. Workshop Restoration – Perform glazing, milling, painting, and repairs offsite

5. Reinstallation – Restore hardware, reinstall windows, and test for operation

6. Finishing Touches – Apply caulking, weatherstripping, and any exterior trim detailing

We coordinate with your design team and inspectors to ensure every detail is correct—from the shape of muntins to the sheen of the paint.
