Specialized installers are RRP (Renovation, Repair, and Painting) accredited to deal with these products without polluting the home.Epoxy Repairs: Rather than changing an entire sill due to small rot, these professionals utilize architectural-grade epoxies to support and restore the wood, preserving the initial material.Glazing Expertise: They comprehend the subtleties of putty glazing and the delicate handling of "wavy" cylinder or crown glass.Hardware Restoration: Historic windows frequently use intricate wheel and weight systems. Installers should know how to re-cord sash weights and restore brass or iron locks and lifts.The Restoration and Installation Process
