Many of the complaints associated with Redwood and Hemlock doors involved the "movement" of timber which means the change in moisture content. This is not the fault of manufacture but a natural effect caused by inadequate protection given to the door when exposed to the elements. If the moisture content is allowed to increase it can cause the timber to swell and twist, and in certain cases to break the joint. The opposite is also true if the timber is allowed to dry out excessively, resulting in shrinkage.
When presented with a complaint, we would ask that you refer to the above checklist so as to establish the validity of the complaint. In accordance with the usual custom of the trade we do no guarantee doors manufactured from Hemlock or Redwood unless it can be proven that there is a case of faulty workmanship.
