The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
South East · England
Crawley was designated a new town in 1947 and built out neighbourhood by neighbourhood in the decades that followed, so most of its housing is post-war rather than period. Self-contained neighbourhoods such as Northgate, West Green, Tilgate, Gossops Green, Broadfield and Pound Hill each have their own mix of estate semis, terraces and maisonettes, generally with trussed roofs and insulation fitted from the outset. An older core survives around the High Street, and newer development continues near Gatwick. For most Crawley homes the loft question is about improving what already exists rather than starting from bare joists.
We help homeowners across Crawley and the surrounding West Sussex area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
The estate housing that dominates Crawley generally has accessible, fairly uniform trussed lofts, and on the earliest neighbourhoods the original insulation now falls short of current standards and suits a top-up. Boards are frequently laid straight onto the joists for storage, compressing the layer beneath. Trussed roofs also limit how storage can be arranged and how freely you can move about the loft. The newest homes near Gatwick usually already meet a good standard, so extra depth adds little, while the handful of older properties around the historic core need a more individual approach.
With so much broadly consistent post-war housing, the useful questions in Crawley are usually whether the existing insulation is even and undisturbed, whether storage boards are compressing it, and whether ventilation keeps pace with a well-sealed roof. Trussed roofs restrict movement and how boarding can be laid, which we factor into any recommendation. Where a bathroom extractor has been run into the loft rather than outside — a common find in updated estate homes — we deal with that before adding insulation over the top.
Even in modern estate homes, condensation appears in Crawley lofts where a well-sealed roof lacks matching ventilation or a bathroom extractor vents into the space. We check for the cause before assuming more insulation will help.
In Crawley, cost is driven mainly by whether storage boards need lifting and reinstating, any ventilation work, and the removal of old insulation on earlier neighbourhoods. Trussed roof layouts can affect how boarding is arranged.
Many Crawley lofts already have some insulation. Where it is sound we can top it up to a suitable wool build-up; where it is damp, contaminated or compressed we remove and replace it. A short assessment tells you which applies.
These are examples of our work elsewhere, shown to illustrate what a project involves. They did not necessarily take place in Crawley.
Emma's front and rear bedrooms, split by a central chimney breast, both cooled quickly. We insulated the 40m² floor on both sides of the chimney to a full 300mm depth.
Example from our project library
Tom noticed condensation on the bedroom windows and rapid overnight heat loss. We gave his compact 31m² loft a full 300mm Knauf glass mineral wool layer, fitted carefully around the hatch and low edge bays.
Example from our project library
Peter's upstairs ran consistently colder than the ground floor even after a heating service. The 46m² loft was almost completely uninsulated, so we installed a full 300mm Knauf glass mineral wool layer from hatch to gable.

We help homeowners across Crawley and nearby West Sussex, from Northgate and West Green to Tilgate, Broadfield, Gossops Green and Pound Hill, as well as Horley and the Gatwick area. Request an assessment and we'll confirm coverage for your postcode.
Often yes. Many of Crawley's earlier neighbourhoods were built with insulation that now falls short of current standards, so a top-up over sound existing wool is frequently worth it. We'll tell you honestly whether extra depth, boarding or ventilation adds the most for your roof.
Yes. Rather than laying boards straight onto the joists, which compresses the insulation, we can fit a raised boarding system that keeps storage above a full build-up — practical in the trussed roofs common across Crawley's estates.
