4. Re-glazing and Weight Balancing If the original cylinder glass is intact, it is cleaned up and reseated. If the owner selects thermal upgrades, experts can often "retro-fit" vacuum-sealed slimline double glazing into the existing sashes. Because contemporary glass or double glazing can be heavier, the professional should re-balance the internal lead or iron weights to make sure the window operates efficiently with a "finger-touch" motion.
5. Priming and Final Finishing When the structural work is total, the window is primed and painted. Expert professionals generally utilize micro-porous paints that permit the timber to breathe while providing a durable barrier against moisture.
