More Log Cabin Information.
Delivery
All our log cabin buildings are delivered on our own vehicles, the larger of these will be delivered on our 26 tonne (42 foot) crane lorry. Being such a large vehicle we will need to know if there are any obstructions, overhead cables or tight corners in the road. Please let us know if any of these may be an issue so we can make other arrangements. Our cabin packs as pictured are usually 1.2m wide by the length of the longest part of your purchased cabin e.g. 5 metres, they are delivered front of house so a space of this size will be required.
Fitting
To ensure your cabin is fitted to the highest standard choose our fitting service, we will take care of transporting the building to the desired location, install a damp proof course, constructing the building, sealing the building, adjust doors and windows and leaving your site free of all rubbish and packaging. After this we will run through with you how to adjust windows and doors in the future, recommendations on painting and aftercare and can offer advice on other landscaping and fencing needs.
Log Cabin Base
Having a level base is the perfect foundation for your timber building, it means that all the panels or logs fit together without a hitch and will settle in unison. The most common bases are Concrete Bases or a timber framed base. Both options provide a fantastic sturdy base for your log cabin.
Painting & Aftercare
All our log cabins are built out of kiln-dried, untreated whitewood for you to decorate in accordance with your taste and style. Please ensure you treat your cabin inside and out as soon as it is fitted. To ensure the longevity of your building it is imperative that you treat any bare timber.
Roof Coverings & Insulation
On our Apex log cabins we use hexagonal felt shingles. On our pent roof log cabins we offer EPDM rubber roofing if required as well as the standard roof shingles
To ensure your cabin is cosy in the winter and cool in the summer you have the option to insulate the roof and floor.
