Underfloor insulation for Lancaster properties
Lancaster sits in Lancashire, roughly 20 miles north of Preston. We work across the LA1 district, including nearby Morecambe, Fleetwood and Thornton-Cleveleys.
We check ventilation as carefully as insulation in Lancaster homes, because both matter for keeping a house dry. Small measures like this are often among the cheapest per pound saved, and they suit Lancaster homes of every age.
As for paperwork, if cavity wall insulation follows in Lancaster, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Keeping the void ventilated
Air bricks under a suspended floor must stay clear so the timbers stay dry. Insulation goes between the joists, not across the void, and gaps at skirtings are sealed to stop draughts.
