Repairing a Cracked Panel

Filed Under: Do it yourself, Home repair, Remodeling    by: ITC

The panels in a paneled door are usually rebated into the stiles at each side. These panels are relatively thin and can easily crack and split, perhaps because of accidental damage or simply through old age.

A crack may have been filled in the past and covered up with layers of paint and it’s only when you strip the door that it becomes apparent. Stripping the door can also loosen the glue holding the panels in place so the panels become free to move and the split opens up even further. A crack of this sort is impossible to fill and if you plan to leave the door unpainted you would not want to see a line of filler anyway.

The only answer is to make a proper repair which forces the crack shut

External door frames can start to rot at the bottom and the rotten parts must be cut out and replaced. Probe into the timber to find out how far the rot extends, then cut out the affected portion plus a further 75mm (3in) of sound timber. You get a considerably neater finish if the new timber is scarf-jointed into the frame.

Remember to treat the ends and back of the new timber with preservative and then screw it in place into wall plugs. If the original frame was machined out of solid timber you will find it easier to make a matching section out of two separate pieces which are glued and nailed together.

If the doorstep is wooden the frame may be tanned into it, so you will have to saw through the tendon in order to remove the defective part. There is no need to try to tendon the new timber into the step.
