Internal Door Installation Information


You should avoid bringing new doors into a building that has recently been plastered or screeded. The extra moisture in the air will find its way into the new doors and will ruin them.

Upon delivery of your doors it is vital that they are stored flat and equally supported.

When the building is suitably aired and dried you can bring the doors in and let them adjust to the environment.

  1. Remove the door from its packaging and offer it up to the frame.
  2. Should it be necessary, mark the door where it needs trimming. If only a small width reduction is required, trim from the hanging edge. For larger reductions, trim equally from both sides but remember that none of our doors are designed to be reduced excessively. Please ask us for advice if you are unsure.
  3. Carefully reduce the door using a sharp plane, or for larger amounts an appropriate saw. Take care to work evenly and avoid splintering on the top and bottom edges where components join together.
  4. Once the door is correctly sized, mark the position of the hinges. Always use good quality hinges incorporating steel washers. Wooden doors are heavy and washered hinges will offer long service.
  5. Using a sharp chisel, cut out for the hinge plates in the door edge to correspond with those in the frame.
  6. Affix the hinges and offer the door up to the frame attaching the remaining hinge plate within the corresponding cut out in the frame.
  7. Fix the latch or lock mechanism to the door edge in the appropriate position. Most locks or latches will be supplied with templates to indicate their correct position upon the door’s edge. In the case of panelled doors, take care to avoid rail joints as this will significantly weaken the joint.
  8. Internal doors should be fully sealed with an appropriate treatment to prevent the free passage of moisture both into the door from within the property as well as to guard against the door losing moisture in the arid conditions which exist within the modern development.
  9. Many of our internal doors are supplied prefinished. During the course of their installation bare edges are often exposed when planing. It is vital that these exposed areas are resealed with an appropriate varnish to ensure that the door is adequately protected against the free passage of moisture.
