The Expertise of a Historic Window Installer

- Structural Repairs: This includes Dutchmen repairs (placing brand-new wood into old) or using consolidants for softened fibers.
- Glass Conservation: Original glass is cleaned up and re-set. If glass is missing out on, installers source historical “salvage” glass to match the staying panes.
- Weatherization: This is a vital step for modern comfort. Installers frequently add covert weatherstripping— such as spring bronze or silicone beads— to get rid of drafts without changing the window's look.
- Re-Installation: The sashes are re-hung, weights are well balanced, and the window is tested for smooth operation.
Choosing the Right Specialist
Not all installers are developed equivalent. When selecting an expert to work on a historic landmark, paperwork and experience are vital.

- Materials Used: Ensure they use premium materials like linseed oil putty and rot-resistant wood species (such as Mahogany or Accoya) for replacement parts.
Suggested Maintenance Schedule for Historic Windows
Frequency
Action
Why?
Every 1-2 Years
Check exterior paint and putty
To catch cracks before water infiltrates the wood.
Every 5 Years
Lubricate sheaves and tracks
Ensures smooth motion and prevents pressure on cords.
Every 8-10 Years
Re-paint outside surfaces
Supplies a fresh UV and moisture barrier.
As Needed
Inspect weatherstripping
Maintains energy performance and prevents drafts.
