Door Care


Timber is a natural product and is subject to humidity and temperature changes. Each door may have slightly different patterns of graining or colour variations. As the timber ages, these colour variations will subside.


The following must be carried out to ensure the best performance from your Deanta door:


On delivery:


  • Doors must be examined immediately on receipt and prior to installation as claims or faults will not be accepted once the door has been removed from packaging.
  • Deanta doors are hand-assembled, and as such, we cannot guarantee each aperture is the exact same size. We recommend you use a qualified glass fitter.
  • Doors must be stored horizontally on a clean, dry, flat and level surface.
  • To allow doors to acclimatise, they should be left in the property prior to installation for at least seven days with the ambient temperature gradually increased over this period.




  • Should doors require alteration, cutting or planning, they must be immediately varnished to prevent moisture absorption which may lead to warping or splitting.
  • Take no more than 3mm off the width and height of doors in equal amounts on all edges.
  • Three coats of internal wood finish are required on any modifications to a prefinished door including the ironmongery and hinge cut-outs.




  • Doors must not be fitted in a property that is freshly plastered and doors should only be delivered to site after all wet trades are finished.
  • We recommend the use of three sets of hinges per door.
  • We recommend only the use of products for sealing against moisture which are suitable for use on interior joinery doors.
