Tanalised treated timber is treated in a way in which Tanalith E treatment is forced into the timber under extreme pressure in a treatment tank, due to this pressure, treated timber only dries out once installed. On average a standard 8x6 shed can hold up to 15-20 litres of water in the wood upon installation. During the drying out period, timber can leak via the knots and shakes in the wood, this is perfectly normal as the wood is now soaking up moisture due to drying out, this is not a fault. Garden buildings - in heavy, persistant rain are NOT 100% watertight, timber being a porous material after prolonged saturation will start to soak water through the cladding, using a high-performance oil based treatment will help to alleviate the extent of water ingress.
Please bear in mind that timber is a natural product that needs care and maintenance, and is subject to naturally occurring changes, which we have no control over. Temperature and humidity can result in some movement of the timber and the roofing material. We use a high grade polyester roofing felt that has a 1 year guarantee, there may be some rippling/movement after installation, this is due to temperature change, it is not detrimental to the building and is beyond our control. This should settle down after a period of time.
We use planed wood in all of our buildings, with all sizes being nominal. Our floors and roofs are made from 12mm tongue and groove boards. A 24mm double skin floor can be made at extra cost.
Joiner made doors and windows are silicone sealed, however heavy rainfall can penetrate after a period of time, no liability can be accepted unless a manufacturer fault is found.
We use standard glass in all of our buildings, we do not guarantee glass. Playhouses are supplied with Perspex. Toughened glass is available on the Contemporary Royal Pent/Apex, at extra cost.
All of our buildings are sold with an anti-rot guarantee, however fair and reasonable care must be given in maintaining your building. We use high grade Redwood from Sweden to clad our buildings, shrinkage, cracks, splits and falling knots are all natural occurrences, with no liability accepted where this occurs, however a high-performance oil-based treatment can help to stop this process ALL buildings must be re treated once they have dried out, we do not offer drying out timescales as each building and location can vary. We recommend the use of a high-quality oil based or solvent based treatment. If water penetration starts to occur, your building is now ready for another coat of treatment. We do not recommend the use of water-based treatments. No liability will be accepted if the incorrect type of treatment is applied to your building. We also recommend that you regularly oil the ironmongery i.e. door and windows hinges/handles. Timber being a natural product may warp, we supply 2 turn buttons to secure the door, these must be used when not in operation to help stop doors warping in climate changes.
fair and reasonable access must be given on the day of installation. Please bear in mind that all sizes are external but do not include the roof/overhang, please allow at least 3-4" all the way around the building for the overhang, Royal buildings carry a minimum of 600mm frontal overhang. Please check for any restrictions or obstacles that will prevent access, including height and width, certain size buildings will not fit through a standard house door, through a ginnel or under an arched gate for example. We can manufacture buildings in modular form for tight access at an additional fee of 20% of the overall cost of the building. We do NOT under any circumstances carry buildings over roofs, car ports, outdoor buildings, fences, walls or over long distances, due to insurance purposes, it is your responsibility to inform us upon ordering, of any issues regarding access to your garden. It is at the discretion of our experienced fitting team to abort the delivery, if they deem access to be unsuitable or too dangerous, to allow installation of the building. A recall fee of 15% of the full invoice total will be payable if access to install the building is not suitable. The building will be left with you and the total balance must be paid to the fitting team.
It is essential that your base is correctly prepared and is solid, flat and level, allowing enough space around the building for installation and maintenance. Bases that are not level can affect the opening of doors/windows or cause the building to twist. All sheds erected upon customers own bases that are NOT level will render the guarantee void and no liability will be accepted for buildings erected upon customers bases under their instruction. It is at the discretion of our experienced fitting team to determine whether or not the base is suitable. A recall fee of 15% of the full invoice total will be payable if your base is not suitable. The building will be left with you and the total balance must be paid to the fitting team.
We take great care when painting your building to achieve the best results and finish. Please be aware that knots can show through the paint, particularly with lighter colours. This is a natural process and cannot be avoided. The timber can be liable to expanding and contracting in certain weather conditions, this is also a natural occurrence and cannot be avoided.
Upon ordering your building we request a deposit, which is refundable if you cancel up to 14 days before your delivery date. If you cancel your building within 14 days of your delivery date, your deposit is non-refundable. Deposits for custom buildings are non-refundable.
any amendments to your order, such as window/door positions, must be made 14 days prior to your delivery date.
