2. Wood Restoration and Resin Repair

Lumber is a resilient material, but direct exposure to wetness can lead to fungal decay-- typically known as damp or dry rot. Specialized repair services often use innovative epoxy resins instead of simply changing sections of wood. This enables the professional to maintain as much of the initial historical wood as possible while creating a finish that is more powerful than the original wood.

3. Draught Proofing Systems

Among the main problems relating to conventional sash windows is their absence of thermal effectiveness. Because the sashes must move, there is naturally a little gap in between the sash and the frame. Professional draught-proofing includes machining discrete grooves into the window parts and installing brush strips or "stack" carriers. This eliminates rattles, decreases dust ingress, and significantly improves heat retention without altering the window's look.

4. Double Glazing Retrofitting

For residential or commercial property owners seeking modern-day thermal efficiency within historical frames, many specialists provide retrofitting services.
