Terms & Conditions

These Terms and Conditions are for the guidance of clients of Trade Oak Garages.

Trade Oak Garages works specifically exclude all ground works, roofing works including felt, battening, tilt fillet, coverings and flashings, staining or finishing of any timber materials, fascia & soffit boards, insulation, damp membranes, fireproofing, M+E services, service connections, internal and external finishing, soak ways, rainwater goods and any other works whatsoever apart from the Oak frame design and associated framing softwood, engineering assessment, manufacture and delivery to site as and if quoted.  Trade Oak Garages are not responsible for any packing or fillets required internally for the application of plaster boarding or other surface finishes other than as detailed in the approved drawings. 


Orders and Cutting Dates

Trade Oak Garages do not hold any buildings or frames for stock, all are made to order.  Orders must be made in writing and be accompanied by an Initial Payment, which allows Trade Oak Garages to schedule a provisional Cutting Date. 


Payments all subject to VAT

Deposit Payment of 25% at time of placing order; Final Payment of 75% due no later than 14 days prior to scheduled mill cutting date.



Upon receipt of each payment a receipted VAT invoice will be issued, where applicable.


Delivery and Storage

Trade Oak Garages will notify a provisional Cutting Date as soon as known to allow Payment Schedules described above to be adhered to.  Joinery work and delivery generally follow within 14 days of the Cutting Date but no guarantee of such timing is given. It is the client’s responsibility to ensure access for the delivery. Due to the nature of the product our delivery lorry is 2.55 metres wide, 11 metres long and 5.5 metres high. If the driver is unable to deliver to your preferred site it is the client’s responsibility to provide an alternative suitable site to deliver to.


Ground Works

Trade Oak Garages will provide a ground work layout drawing and typically expect brick work to be within the following tolerances:

Concrete to be poured to a maximum tolerance of +/- 3mm level per 1m length.

Concrete to be laid to within 3mm of the dimensions stated on the drawings supplied.  Should dimensions be missing from the drawings, the contractor should contact Trade Oak barns and not make any assumptions.

Brickwork to be within +/- 3mm of plumb per vertical metre. 

Brickwork to be laid within +/- 3mm per 1m run along the length of a wall.

Brickwork levels to be laid within +/- 10mm of level per 5m length.

The top course of brickwork to be laid ‘frog down’ where sole plate is to be fixed to it.


Should the Client become aware of delays for any reason that would adversely affect the delivery the Client must inform Trade Oak Garages prior to the Cutting Date so that new payment & delivery dates can be arranged. Failure to notify Trade Oak Garages of delays as above will render the Client liable to any & all additional costs incurred as a result of having to reschedule cutting, delivery & assembly.


Oak Staining, Movement, and Properties.

Unseasoned (“Green”) Oak will leach tannin if it gets wet and this will temporarily discolour the wood and adjacent brickwork.  It can be cleaned, sanded or left to weather away.  In the case of internal timbers, any tannin which leaches during construction is unlikely to weather away.  In this case, the client may choose to sand blast timbers prior to fit out, or sand timbers to remove the staining.  Trade Oak Garages do not remove any staining caused by tannin unless previously agreed specifically in writing.

Green Oak is a naturally very durable raw material.  It has been used in its raw form in general construction, shipbuilding and mining for many centuries.  Trade Oak Garages do not treat any of its Green Oak timbers with stain, preservative, fungicide or pesticide - it is the client’s prerogative to do so. The green oak used in our oak frames is natural and as such may shrink, warp, crack or display natural wood defects. Trade Oak Garages cannot accept any responsibility for any of these characteristics unless they are proven to be detrimental to the structure.

The sapwood of the Green Oak may be affected by beetle such as True Powderpost.  This beetle eats starch found in the sapwood until it is ready to mate when it leaves the timber and the exit hole is seen.  A deposit may be visible which looks like powder, hence the name. 

When the engineering calculations are prepared, the loss of this sapwood element, shrinkage, warping, cracking and natural wood defects are all taken into account.  Indeed the loss of elements of sapwood over time as the timbers dry and harden are very much part of the nature and charm of using Green Oak.  Observing timbers of Oak buildings centuries old will frequently demonstrate the powderpost beetle at work, which is why some beams will not have remained square edged, and have the attractive wane to them.  Sapwood is sometimes ground away in production or left square edged.  If a specific finish is required, please let us know at quotation stage, as this needs to be taken into account when preparing the quotation.



The oak structure of the building is underwritten by Professional Indemnity Insurance and is proven by the engineering calculations provided with each building.

Green Oak is a natural material and may split or 'shake' during drying; this represents no long-term adverse effect on quality.

Trade Oak Garages will replace or repair any oak frame member which fails for any reason attributable to its inherent strength or our process thereof, provided (if in doubt) such reason is verified by an independent and suitably qualified Structural Engineer and provided that the building or its use has neither been varied from its original design without our written permission nor subjected to physical damage.


Other Timber

Any structural softwood used is pre-treated with Vacsol Aqua, a biodegradable fungicide and insecticide, against rot and infestation.  Vacsol Aqua conforms to the efficacy requirements of BSEN599-1 1997, and is treated in accordance with the penetration and retention guidance given in BSEN351-1 1996 to give a desired service life in the selected hazard class as defined in BSEN335-1 1992. Although it has been treated the cladding will require subsequent coats of a maintained surface coating such as a wood preserver or water seal periodically throughout its life. As with the Oak, any softwood cladding will weather down to a natural grey colour.


Softwood windows, doors and stair cases are treated with one coat of stain or clear preservative to seal the timbers. The joinery will require another coat immediately after installation, along with a further coat within three months. Additional coats should be applied periodically in accordance with the coating manufacturer’s instructions. It is the client’s responsibility to apply these further treatments as necessary.



All prices quoted are subject to VAT at the standard rate unless otherwise specified.  However, certain projects, typically new-build houses for domestic occupation or certain works to Listed Buildings may be zero-rated. Clients will be required to provide suitable evidence to support the application of any zero-rating.



Trade Oak Garages accept no responsibility whatsoever relating to the compatibility of other elements of the building with the Oak frame, where they are installed by others.

Trade Oak Garages are responsible for the production of Engineering Calculations for the purposes of justification of the integrity of the frame unless the design has been engineered by external parties.  Under an agreement whereby Trade Oak Garages are contracted to produce the Engineering Calculations for Building Regulations purposes, these may be submitted to the Building Inspector for these purposes. 

Trade Oak Garages are not responsible for the specification of any other elements relating to achieving Building Regulations. Specifically this does not include vapour barriers, insulation thicknesses, fire protection or any other elements pertaining to Building Regulations.  It is the responsibility of the Client to handle all Building Regulations requirements as and when they or their agent applies.


Shortages and Damaged Goods

The client should check the delivery on receipt and note any shortages or damage on the delivery note. Any shortages or damaged goods noted will be delivered within a 7 working day period from the original delivery date.

Any returns should be made within 7 days of delivery and is the responsibility of the client to organise transport. If the building is in good condition and as per agreed drawings Trade Oak Garages will not be liable for costs incurred.
