Paint Removal and Timber Repair Old, lead-based paint layers are typically stripped back to reveal the condition of the wood. windowsanddoors-r-us use "fitching" and resin repair work techniques to restore initial timber. If a section is beyond repair work-- typically the bottom rail or the sill-- the professional will carry out a "splice" repair work, cutting out the rot and signing up with a new piece of skilled hardwood or Accoya ® lumber.
3. Draught Proofing Integration Among the primary complaints about old windows is the "rattle" and the heat loss. Professionals set up discreet brush strips into the beads and the meeting rails. This creates a seal that removes drafts and sound pollution without jeopardizing the window's appearance.
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. Since modern glass or double glazing can be much heavier, the expert must re-balance the internal lead or iron weights to make sure the window runs efficiently with a "finger-touch" motion.
5. Priming and Final Finishing When the structural work is complete, the window is primed and painted. Expert specialists usually use micro-porous paints that enable the wood to breathe while supplying a long lasting barrier versus moisture.
