Weather damage is often a very typical cause of damage UPVC window seals. Especially in the UK, were we have to occasionally deal with very hot summer days and very cold winter chills. Once the seals on a UPVC window or patio doors become damaged, it can cause a home to lose heat, and it reduced the energy efficiency in a property too. 
We attended this appointment after giving the homeowners a quote and timeframe for the work. One of our local UPVC repair technicians got the window seals replace in this Stanwell, Middlesex property on the same day.
