Slim Cavity Units for Portishead properties
What makes Slim Cavity Units work in Portishead is usually invisible once it is finished. Around here it is Georgian Clifton terraces, Victorian bay-fronted streets and converted warehouses, and that alone rules out anything bought by the pallet. What accelerates it is mild wet westerly weather with limited hard frost, and moss and algae growth followed by paint blistering on shaded elevations follows sooner than owners expect. This is really a job about narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Photographs and approximate sizes are all we need to start.
One local point to factor in: Clifton's Georgian stock frequently requires exact sash box replication.
