Door Finishing & Care - Important Info

How Best To Prepare Your Door For Installation And Beyond. This info is vital in you treating your new doors to perfection.


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

We offer a limited ten year warranty on all our doors. Any door that warps* or splits will be covered by our warranty once the installation has met all guidelines. Please note colour variance in the wood is not considered a manufacturing fault as it is a natural product.

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

– 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.

– All doors must be measured individually when having glass fitted. Most 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 your door to acclimatise, it should be left in the house prior to installation for at least 7 days with the ambient temperature gradually increased over this period.

– Should your door require alteration, cutting or planing, it must be immediately revarnished to prevent moisture absorption which may lead to warping or splitting.

– Take no more than 32mm off the width and height of your door in equal amounts on all edges.

– 3 coats of internal wood finish are required on unfinished doors and on any modifications to a prefinished door including the ironmongery and hinge cut-outs.

– Your door must not be fitted in a house that is freshly plastered and doors should only be delivered to site after all wet trades are finished.

– We recommend the use of 3 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.

Interior Doors

Oak doors should avoid oils as a finish.

A Paint, stain, wax, varnish or a lacquer is recommended. Untreated products must be fully sealed prior to hanging, this applies to all surfaces including tops, bottoms, and all recesses cut for hinges, locks, handles and letter plates.

Please do not use a water based sealant as if applied too liberally it may penetrate the veneer and may cause bubbling to occur.

Exterior Doors


Door Construction

Most of our internal and external doors are manufactured using engineered component parts. This enables us to provide a product that offers a solid feel, combined with all the advantages that engineering brings in terms of strength, consistency and stability. All of our engineered doors are faced with veneers and matching lippings.

For many years now, the availability of raw materials has resulted in it being increasingly necessary for door manufacturers, importers and distributors to develop a more sustainable approach to the production of timber doors.

This has culminated in an increasing number of manufacturers producing doors using engineered components with a veneered and/or LVL facing. We work closely with our suppliers to ensure that this practice is executed in such a way that providing the doors are fully protected on all exposed/tooled parts from the climate and atmosphere using a suitable finishing product, you will enjoy many years of effective, enduring service from these technically superior products.

We must however stress that the suitability of the chosen finishing product should be comprehensively verified with the manufacturer of the respective treatment to ensure validation of the robust manufactuers Guarantee.

Any products which remain as non-engineered construction, also require the same level of protection.


All doors supplied by Leeds Plywood & Doors Ltd, hereafter referred to as LPD (except those doors expressly excluded from this guarantee by LPD, effective as at 1st November 2004) are guaranteed by LPD for ten years from date of delivery, and at that time, to be of good material and workmanship and to be free of defects which would render said doors unserviceable and/or unfit for the ordinary, recommended use.

This guarantee is made to the original purchaser only and does not extend to subsequent purchasers during the period of this warranty.

If at the time a door delivery is received, said door(s) are found to have a defect(s) which can reasonably be discovered by inspection of each door, the receiver of the door(s) must, prior to hanging or fitting, and within 3 days, send written notice of said discovered defect(s) to LPD. All doors should be fully inspected prior to altering or fitting - any work undertaken on the door shall constitute acceptance.

If a fault rather than defect develops after the door is fitted, written notice of said fault(s) must be sent to LPD within ten years from date of delivery.

No claim will be honoured unless an authorised representative of LPD performs a site inspection (at the discretion of the company).

If guaranteed doors are found to contain defects/faults as stated herein, LPD, at our option will either, repair defective/faulty door(s), furnish purchaser with replacement door(s) or refund to the current owner the amount the original purchaser paid LPD for the returned defective/faulty door(s). This guarantee does not cover any other charges incurred such as labour for removal of defective door, rehanging of new and/or replacement door, transportation to and from site or reimbursement for any other work/service not originally supplied by LPD.


Limitations & Exclusions

  1. service or appearance caused by failure to follow the "Handling/Finishing/Installation" instructions set out herein or similarly in the alternative contained within the door packaging are excluded from this guarantee.
    Natural variations in the colour or texture of wood are not to be considered as defects.
    Warp/bow/cup/twist (as set out in the relevant British Standard) shall not be considered a defect unless it exceeds 1/4 inch (6.35mm) in the plane of the door itself. Warp is any distortion in the door itself and does not refer to the relationship of the door to the frame or jamb in which it is hung.
    When measuring the amount of warp in a door, the following method shall be used: bow, cup or twist shall be measured by placing a straight-edge on the suspected concave face of the door at any angle (i.e. diagonally, horizontally, vertically), with the door in its installed position. The measurement of bow, cup and twist shall be made at the point of maximum distance between the bottom of the straight edge and the face of the door. Shrinkage/swelling/splitting shall not be considered as a defect.
    Experience demonstrates that when warp occurs after delivery, it is usually due to improper storage or adverse moisture conditions after handling, not to faulty manufacture. The manufacturer will accept no responsibility for the development of warp when the moisture content of the timber falls below 12% or exceeds 18%. Obviously, the manufacturer cannot assume responsibility for conditions wholly beyond its control. The manufacturer should, however, be consulted promptly if excessive warping occurs to assist in overcoming the difficulty.
    The guarantee on Double Glazed Units is restricted to 5 years
    All the following doors are excluded from this guarantee:
    i. All Knotty Pine doors and Door Blanks.
    ii. All non-stock/special doors, which fall outside of the usual LPD standard stock size profile (i.e. special orders).
    iii. All doors that are improperly hung or do not swing freely.
    iv. Normal wear and tear including wear through of finish.
    v. The appearance of any door with non-factory applied high gloss finish.
    vi. All doors stored on sites other than the properly prepared storage areas/warehouses of LPD’s client/customer, other than for reasons of satisfying the relevant paragraphs of the Handling, Finishing and Installation category set out below.
    vii. All doors not supplied finished by or not finished prior to installation.
    viii. Any product treated with a water based finish.
    ix. All exterior doors where there is inadequate overhead protection.
    x. Any installation LPD deems structurally unstable - this will be noted in writing by LPD.
    LPD shall not be liable for any doors repaired, returned or replaced without prior consent by LPD.
    Upon receipt of delivery of doors, inspect each door for any visible defects. Doors should be stored on a flat and level surface in a dry, well-ventilated building. Cover to keep clean and keep out sunlight, but allow air circulation.
    Handle with clean gloves and do not drag doors across one another or across other surfaces.
    Doors should not be subject to: abnormal heat, extreme dryness, humid conditions or sudden changes therein. They should be conditioned to average prevailing relative humidity of the locality before hanging.
    The utility or structural strength of the door must not be impaired in the fitting of the door, the application of the hardware, or cutting and altering the door.
    Before finishing, remove handling marks or effects of exposure to moisture with a thorough final sanding over all surfaces of the door using fine sandpaper. Clean before applying sealer or finish. Some species of wood contain a chemical (oak particularly), which reacts unfavourably with certain finishes. Where possible, the surface should be tested for such unfavourable reactions. Application of a sealer before finishing will usually prevent this difficulty. Do not use steel wool or other sanding materials containing steel/iron on Oak doors.
    Immediately after fitting, or cutting for closures, weather-strip and/or threshold, and before hanging any interior or exterior door on the job, the entire door, including the top and bottom edges must receive an application of a suitable sealer/primer and two coats of a good grade of paint, varnish, lacquer, micro porous wood finish. Always check with the manufacturer of the chosen finish to ensure suitability and/or compatibility with the particular construction and specie of your door choice. . Adequate drying time must be allowed between coats. For job site finishing, do not use a water-thinned paint unless an oil base prime coat is first applied. Exterior finishes shall be used on the faces and all edges of exterior doors.
    Avoid dark colours on exterior doors in direct sunlight.
    All doors should be checked prior to installation. The working upon or installation of these doors shall constitute acceptance.
    There are no warranties that extend beyond the foregoing, and LPD's responsibility under this guarantee is as stated herein. LPD shall not be liable for consequential, incidental damages, or for any amount in excess of LPD's original invoiced price for the doors involved, whether the claim is for breach of guarantee or negligence.
    LPD attempt to do everything that is reasonably possible so as to ensure that the relevant British Standards that relate to wooden doors are met or exceeded.
