Cracks between walls and woodwork such as skirting boards and door frames are a natural part of the drying out process and not a sign of structural faults or poor workmanship.

Only cracks that are more than 3mm wide (the width of a pound coin) are covered by your warranty. Minor cracks are normal in a new home, and easy to fill and make good. Just follow these simple instructions.

Before you get going, make sure you have the following tools to hand:
  • Tube of white decorator caulk
  • Sealant gun
  • Sharp knife
  • Latex gloves

  1. Cover the floor underneath the crack with a dust sheet
  2. Unscrew the nozzle from the tube of caulk and cut off the seal
  3. Replace the nozzle and trim the end at a 45-degree angle
  4. Load the tube into the sealant gun
  5. Squeeze out a line of caulk along the crack with the longer side of the angled nozzle
  6. Wet your finger and smooth the caulk into the crack
  7. Leave to set until the caulk is completely dry
  8. Touch up the paintwork to match the rest of the surface
