Recommended Treatment and Handling of Joinery

Although it is presumed that people involved with the joinery supplied today in the Building Industry are familiar with the correct storage and handling of timber products, experience shows that this is incorrect. 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 subject to extreme changes in heat or humidity (e.g. open-sided corrugated iron sheds, containers).

  • 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 the 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 protection.

  • 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 elements i.e. whether north facing etc and the degree of protection afforded by the overhang of roof, awnings

    etc, depending on the 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, doors must be trimmed equally from both sides, top and bottom. A maximum of 5mm from each edge and a total of 10mm in the width, a maximum of 10mm off the top and a maximum of

    15mm off the bottom and a total of 25mm in height.

  • 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 programme at the outset.

  • Doors must be sealed immediately on all six sides and be fitted with a lock and not allowed to wing 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.

  • Any door found to have a factory fault will be replaced free of charge within 6 months of delivery. Kindly inspect doors

    for patent defects before fitting and hanging. Doors with patent defects that have been fitted and hung will not be exchanged. We shall not be held responsible for any incidental work or expenses arising out of, or because of, any defect in our product and our liability shall in no case exceed our invoiced price.

    In conclusion, all external timber doors must be maintained throughout their lifetime. Failure to do so allows loss or gain of moisture depending on prevailing conditions. The abuse of joinery and its treatment are extremely prevalent. Regular maintenance must be maintained as mentioned earlier. Once deterioration and discolouration, 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 shrink- age 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 rain- fall period will absorb moisture to equilibriate 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, shrink- age, warpage etc. will be impossible to avoid. This is the basis on which manufacturers world wide expect joinery products to be handled. Solid Doors reserves the right to discontinue any line or product, and change specifications and construction details without notice.
