All Cabins for Schools buildings come with our ten year manufacturer’s warranty. This warranty guarantees replacement of any component parts should they be found to be defective within this period, however it does not cover accidental damage or weather damage once building is constructed. Customers should also note that timber is a natural product and prone to changes in appearance, including some movement and the occurrence of small knot holes or splits in extreme temperatures and weather conditions. Splits, knots or similar visual imperfections in the timber not affecting the structural integrity of the building will not be accepted as a valid reasons for a claim against our warranty.
This is in addition to our suppliers warranties/guarantees.
Roofing Shingles – we only use CE-marked Kerabit High-performance SBS modified roofing shingles which are guaranteed for ten years.
Any timber bases we fit are supported on “TANALISED” timber which has been impregnated with a preservative solution under high pressure in an industrial vessel. This treatment process ensures deep penetration into the timber cells, for a longer-lasting protective result against fungal decay and insect attack than the application of a surface coating. Pressure-treated timber is leach resistant, ensuring a long and trouble-free service life in a wide range of conditions, and assured performance in sensitive environments such as vegetable plots and areas of wildlife. Desired service lives range from 60 years for internal timbers and 30 years for external timbers such as fence posts in ground contact.
Should any defect occur to our UPVC or Aluminium Windows, Doors (including Bi-Folds) within the specified time limit from the date of installation due to defective materials or workmanship, we undertake to replace the faulty parts free of charge provided that:
The product has not been misused or carelessly handled.
The product has not been subjected to extreme heat or low temperatures, impact, industrial emissions, chemicals or abrasives other than would be used for normal cleaning purposes.
Repairs have not been attempted by people other than our own staff.
Damage to any product has been reported to the installation team prior to them leaving site.
Background Ventilation – Best Practice Guide
It is important that the dwelling can constantly breathe, good air quality is important for health and also helps protect the fabric of the building from harmful effects of mould and condensation etc. Background ventilation such as trickle ventilation (if specified) and night vents (standard on our casement windows) can help to achieve this.
Please ensure all ironmongery is cleaned and lubricated every six months.
We recommend silicone spray or WD40 to lubricate window hinges, window locking mechanisms and door locking mechanisms. In addition they should be kept clean and free from debris.
Please ensure that composite doors are kept in the locked position or ensure that the handle has been lifted so the locks engage into the outer frame.

Exterior Timber Finishes
Timber that is unprotected and exposed to rain and sunlight will start to break down fairly quickly (depending on the species of timber). This deterioration will cause surface checking (cracking) due to the moisture change within the timber. The timber will lose its natural colour and bleach to various shades of grey spoiling the appearance. Dimensional changes in the timber resulting in changes in moisture content may also have detrimental effects on exterior joinery, windows and doors, which for instance may swell and be difficult to open and close.
If you have specified that your Cabin is supplied unfinished we recommend you apply a paint, stain, clear water repellent, or other finish as soon as possible after installation and periodically thereafter (in accordance with the manufacturers recommendations).
All of the timber we use in our buildings is sourced from FSC or PEFC certified suppliers. The FSC (Forest Stewardship Council) is a global organisation with the aim of ensuring the chain of custody of all timber products and that the sourcing forests are properly managed to ensure sustainability. This means that more trees are planted than those that are used. It also ensures fairness for the indigenous populations where these forests are located.
PEFC (Programme for the Endorsement of Forest Certification) is the largest worldwide forest certification system with around 220 million hectares of certified forests. Their aims are all associated with the sustainability of the supply of timber and doing that in an environmentally friendly way.
Both processes tracks timber through each stage of the supply chain, from felling through milling, transportation, import, distribution and finally to the point of use. This provides a level of transparency and traceability to guarantee compliance with demands for ethically sourced timber products.
