Old, lead-based paint layers are frequently stripped back to expose the condition of the wood. Specialists use "fitching" and resin repair work techniques to restore original lumber. If a section is beyond repair work-- frequently the bottom rail or the sill-- the expert will perform a "splice" repair work, cutting out the rot and signing up with a new piece of skilled wood or Accoya ® timber.
3. Draught Proofing Integration
One of the main problems about old windows is the "rattle" and the heat loss. Experts set up discreet brush strips into the beads and the meeting rails. This produces a seal that removes drafts and sound pollution without compromising the window's appearance.
4. Re-glazing and Weight Balancing
