The Garden Arc warranty is subject to the customer following the checks and maintenance procedures listed; and to notify Alfresco Arch of problems immediately they occur. Failure to do so will void your Garden Arc warranty.

Checks and maintenance procedures

Products and Buildings, Manufacture and Materials are supplied with a 10 year limited Warranty subject to the following terms :
The guarantee does not cover movement, warping, splitting of timber products over time.
Any warranty offered is only valid for goods within the United Kingdom.

Canvas sleeves
Apply a quality waterproofer such as 'Frogsuit' to the front arch canvas cover before each winter. (Ensure the cover is completely dry)

The standard spruce cladding can last up to 10 years untreated. If the cladding starts to look tired, simply apply a good quality decking oil to the cladding to help to protect the wood.

It is important that you keep the ventilation under your arc clear from plants, earth etc. Check this on a regular basis making sure that there is a gap underneath the deck.

Treat the outside deck with a quality deck oil every year.

Apply 'Frogsuit' decking oil to the window frames to protect the soft wood frame.

Validity of Guarantee
The product build instructions must be adhered to in order to comply with the conditions of the guarantee. If any part of the building is cut, notched or drilled such actions must also adhere to the build instructions.
Owners and users are required to notify Alfresco Arch of problems or failures immediately they occur.

The guarantee is invalid if:
The building has been customised or modified in any way.
The person claiming is not the original purchaser of the building.
The building has not been erected, fitted or installed correctly by a trained employee of Alfresco Arch.
The building is or has been touching any external wall or vegetation which can allow moisture to penetrate the timber.

General Information
Wood is a natural product and susceptible to changes in the external environment. Extremes of temperature or weather conditions will cause a reaction in the timber. Sawn timber and machine rounded items in particular may split. This doesn’t necessarily affect the structural strength of the wood or the product

Products and Buildings include all those advertised, specifically described and sold by Pan Products Ltd (also trading as AlfrescoArch) which incorporate its patented arch support structure; these include its Arch Building designs and all their derivatives which make up its product range at any time.
