Granny Annexe Warranty
You have a one year structural warranty as standard.
How long will the annex last
Beyond the first year, the annex should give ou many, many years of life, provided you treat it occasionally with a good quality wood treatment, and properly maintain it, as you would expect with any wooden structure.
For instance, after six years of use, we disassembled and moved a small office, made of the same pine material, although thinner walled with no insulation or cladding. With only two treatments of wood preserver used during that time, there was no visible structural degredation anywhere on the kit.
Low maintenance product
All of our annexes are low maintenance. However, for a lower maintenance option, the Thermowood option has a ten year guarantee on the cladding, without treatment, reducing the maintenance still further.
The roof is finished off with Katepal 15 year Felt roof shingles - see specifications for the full specification list.
Our warranty is pretty comprehensive but there are a few things that we cant be in control over. for instance, if you break the glass in the windows and doors or if a door swings off its hinges due to a strong wind whilst it is left open, then this is not covered. The fixtures and fittings within the property are also covered by a one year manufacturer's warranty.
