2. Timber Restoration and Resin Repair
Lumber is a resilient product, but exposure to wetness can cause fungal decay-- typically known as damp or dry rot. Specialized remediation services typically utilize advanced epoxy resins instead of just changing sections of wood. This permits the expert to protect as much of the initial historical wood as possible while creating a finish that is more powerful than the original wood.

This gets rid of rattles, lowers dust ingress, and significantly enhances heat retention without altering the window's appearance.

For home owners seeking modern-day thermal performance within historical frames, lots of experts offer retrofitting services.
