Replacing a conservatory roof in Eastbourne: what is different here
Eastbourne was laid out largely in the Victorian era as a planned seaside town, and it regularly records some of the highest sunshine totals in the UK.

Homes near the seafront are also exposed to salt and wind, so ask about the frame finish guarantee.
