Retrofit Double Glazing for Knowle properties

Retrofit Double Glazing is one of those jobs in Knowle where the survey decides everything. Because the area is mainly Georgian Clifton terraces, Victorian bay-fronted streets and converted warehouses, no two openings measure quite the same. Set against mild wet westerly weather with limited hard frost, most joinery here eventually shows moss and algae growth followed by paint blistering on shaded elevations. Where we put the effort is reworking the rebate so a sealed unit fits without bulking the section.

We check on site before committing anything to the saw, and we query what does not add up. Give us the basics and you will have a written figure, not a range that moves later.

Local factor worth flagging early: Clifton's Georgian stock frequently requires exact sash box replication.
