This might be a daft question but I will ask anyway.
We are about to commence a self-build. We will be doing the majority of the work ourselves apart from (possibly some groundworks (i.e. dig footings), flat roof covering (to get a guarantee), window installation (to get a guarantee & size/weight of some of the doors - 6.5m sliders) & electrics.
Each of these would come with there own guarantees/warranty, any other build issues would be down to me as I would be doing it.
So what would I gain from a warranty? Any issues a warranty provider would presumably come after me anyway as the "builder" so no point in insuring?
