- Please inspect carefully for correctness, quality and size prior to any cutting finishing or fitting. Failure to do so will invalidate any claim.
- Doors should be stored only in dry rooms with normal humidity.
- Moisture from damp floors and screeds must be avoided.
- Never store doors in an area where they will be subjected to extreme changes in heat or humidity (e.g. open sided corrugated iron
- Store doors flat on four evenly spaced dunnages approximately 100mm off the floor to avoid twisting.
- Doors should be handled carefully to avoid scratching and other damage.
- The top of the door in the stack should be covered with a suitable material such as plywood, hardboard or cardboard to avoid bow
due to loss of moisture on the exposed surface.
- Doors after manufacture will still be subject to shrinking, swelling and warping, as any wood product is, when exposed to dramatic changes in dryness or temperature and humidity.
- All joinery products, i.e. doors and framing should be sealed immediately after delivery onto site and before hanging, on all six sides to avoid gain or loss of moisture depending on local conditions. It is imperative that doors be sealed on all six sides after trimming
to size and before fitting.
- Avoid hanging doors in an open out rebate where they will be exposed to the weather eg. where there is no sufficient overhang or
- At least three coats of a recommended sealer should be applied within twenty-four hours of one another, to all six sides of the door.
- Timber doors must be maintained by the client and re-sealed regularly at least six monthly, dependent upon the exposure to the element
i.e. whether north facing etc. and the degree of protection afforded by the overhang of roof, awnings etc. depending on type
of finish used.
- Timber products will be degraded and have a reduced aesthetic and functional life span if neglected.
- Proper care and attention should be paid to levels to allow for screed thickness.
- Not to impair the structural strength of a door a maximum of 5mm trim is allowed from any side, top or bottom. Doors must be
trimmed equally from both sides top and bottom.
- Endeavour to only hang doors as near as occupation as possible to avoid damage due to banging, whilst left open. Fit this into the production program at the outset.
- Doors must be sealed immediately on all six sides and be fitted with a lock and not allowed to swing freely and bang.
- Contracts such as schools and compounds must have cabin hooks fitted immediately to prevent damage.
- All exterior doors should be fitted with a weather bar.
- all external timber doors must be maintained throughout their life time. Once deterioration and discoloration, peeling and flaking of the sealer is noticed, a medium sandpaper should be used to remove “dead” sealer and then resealed.
- Timber is extremely durable if handled in the proper manner, but it is essential that the initial storage, trimming and sealing is done correctly.
- Medium hardwoods obviously exhibit less of a tendency to shrinkage than light hardwoods and this should be borne in mind.
- Most problems generally occur when the product is removed from storage and having been manufactured during the summer rainfall
period will absorb moisture to equilibrate moisture in the air. If doors are then exposed to greatly reduced moisture in the air, i.e. in winter,
and are not treated and sealed immediately, shrinkage, warping etc. will be impossible to avoid.
- To assess whether the opening of a door frame is square or not and to determine how much will have to be trimmed off the door, measure the diagonals of the door frame. There should ideally be a maximum clearance of 5 mm at the bottom of the door and 3 mm clearance on
the other three sides. To reduce in width, remove equal amounts up to 5 mm from both sides and up to 6mm from the top and bottom of the door, again equally for reductions in length of the door.
- If hinges are not on the door frame already these should be fitted at
+/- 180 mm from both the top and the bottom of the door frame prior to any measuring or marking.
- Place the trimmed door in the opening and wedge it into position both
top and bottom.
- Mark the hinge positions on the door edges from the hinges on the frame,
then remove the door and extend the markings over the edges prior to scoring.
- The hinge outlines are now scored with a chisel.
- Cut the recess into the door and frame, ensuring the hinge is flush with the edge of the door. The screw holes are now marked and drilled.
- The hinge recesses are cut slightly deeper on the inside of the frame so
that the hinge is not completely closed when the door is closed. The
thickness of the hinge leaves at the knuckle and the recess depth should be the same. The knuckle should protrude from the frame and the door.
Use a marking gauge to obtain the same depth for each hinge.
you not succeed in setting the hinges evenly in the frame the door will not
swing freely necessitating time consuming adjustment. Should the door
not close easily the hinges need adjusting.
- Once the hinges have been positioned correctly they can be screwed

responsible for how doors are installed and maintained on site.
