Recent floor insulation work near Orpington
Orpington's 1930s and 1950s semis in Petts Wood, Chelsfield and Locksbottom typically have suspended timber ground floors over a ventilated void — good for the joists, bad for warmth. Where there is crawl-space access we fit insulation from below without lifting a single board, which keeps most jobs to 2–3 days. From the 59 floor projects we have priced, typical rates run £76–£110 per m², and we pair the work with airbrick checks so the void keeps breathing after the insulation goes in.

Why Orpington homes benefit from floor insulation
Real comfort improvement
Most Orpington homes lose 25-35% of their heat through uninsulated walls or roofs. Floor Insulation cuts that loss dramatically and eliminates the cold spots and draughts that drive heating costs up.
Lower bills
Savings depend on the starting point, the measure and your tariff, so we give you an honest estimate at survey rather than a headline figure. Loft and floor insulation pay back fastest; wall insulation saves the most on solid-wall homes.
Adds value
Insulation lifts the Energy Performance Certificate score, which buyers and lenders see, and landlords need a good EPC to keep letting. We lodge the work with TrustMark so it is on record when you sell.
