Bit off-topic…. Anyone in the SE area needs double glazing done let me know.
Just had mine done by a family friend at 20% of the quote given by the big nationals and 50% cheaper than the next best quote. I chose the profile, glass etc and he ordered (wholesale) and installed. The job done is incredible, 7 windows fitted by team of 4 in 8 hours with no tea breaks etc…. very pleased and therefore happy to recommend.
