The start of my exterior work begins once the risk of frost has receded. Work usually continues until shortening days and increasing humidity abruptly interupt progress, this usually happens sometime in October and i take bookings untill the end of september. Small jobs may be taken on after this point but weather becomes steadily less reliable. Outside may-sep i`m focused on indoor work.
There are gaps in my schedule. These are firstly to allow for prolonged poor weather–occasional bad days will be dealt with by working at the weekend; secondly gaps allow contraction of my schedule and fitting in small jobs if the weather remains fine.
