Insulation Installers in Ruislip

Yes — we cover Ruislip and all surrounding Greater London postcodes (HA4). Most surveys can be booked within 3-5 working days, with a written quote sent within 24 hours of the visit.

Ruislip is dominated by inter-war semi-detached estates built between 1925 and 1940 — cavity-walled, suspended timber floors, and original loft insulation often still in place. EWI on rear elevations is increasingly popular as homeowners stop short at the planning-sensitive front facade. The right choice depends on your wall construction (solid vs cavity), property age, and whether external alterations are permitted. Our free survey identifies the most cost-effective option for your specific home.

Costs depend on property size, access and the measure: loft top-ups about £1,600–£2,700, floor insulation £2,500–£6,000, internal wall insulation £100–£140/m² and external wall insulation £110–£140/m² for the system (finished EWI jobs £176–£232/m² all-in). Every Ruislip quote is free, fixed and itemised after a survey — no surprises.

Loft top-ups are usually a 1-day job. Floor insulation takes 2-4 days depending on access. Internal wall insulation runs to 1-2 weeks for a full house, and external wall insulation typically 2-4 weeks including render and decoration.
