Crawley
Spray foam, loft insulation and damp in Crawley homes
Crawley was designated a New Town in 1947 and built out neighbourhood by neighbourhood. West Green, Northgate, Three Bridges, Langley Green, Ifield, Gossops Green, Southgate and Tilgate came first, in the 1950s and 1960s. Furnace Green, Pound Hill and Broadfield followed, then Bewbush, Maidenbower and, most recently, Forge Wood.
That gives Crawley a housing stock unlike most Sussex towns: thousands of post-war terraces, semis and maisonettes built to the standards of the day, with very little loft insulation when they went up. Many have since had a thin top-up, but plenty still sit well below today's guidance of around 270mm. Shallow-pitched roofs on some estates make lofts tight to work in, so the job needs planning.
The old village core survives along the High Street, with medieval timber-framed buildings and later fronts inside a conservation area. Homes like these need breathable materials rather than a modern quick fix. Lime plaster, lime mortar and clear ventilation keep old timbers and brick dry, while cement and sealants trap moisture and cause the very damp they were meant to stop.
Damp in Crawley is mostly condensation in post-war homes and ground moisture on the Wealden clay. Poor ventilation, blocked air bricks and cold spots where insulation is missing are common causes. Spray foam turns up too, often sold as a fix for draughty roofs. We remove it by hand, clean the timbers back, and reinsulate with Knauf mineral wool to 300mm.

Questions we get in Crawley
Do you cover all of Crawley?
Yes. We cover Crawley across RH10 and RH11, including Three Bridges, Pound Hill, Tilgate, Broadfield, Bewbush, Ifield and Maidenbower, from our Sevenoaks office. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed, with no pressure and no obligation to go ahead.
Do Crawley New Town homes need more loft insulation?
Many do. Homes built in the 1950s and 1960s went up with little or no loft insulation, and earlier top-ups were often only 100mm to 150mm. Current guidance is around 270mm. We clear what is needed, lay Knauf mineral wool to 300mm and keep vents clear, so the loft stays dry as well as warm.
Why do I get condensation and mould in my Crawley home?
In many post-war homes it comes from moist air meeting cold surfaces. Missing loft insulation at the edges, blocked air bricks and poor extraction in kitchens and bathrooms all make it worse. We check whether you have condensation, rising damp or a leak before recommending anything, because each needs a different fix.
Can you insulate a loft with a shallow roof pitch?
Usually, yes. Some Crawley estate homes have low-pitched roofs, so there is less room to move. We plan the job at the survey, check access and ventilation at the eaves, and use mineral wool that can be laid carefully into tight spaces. You get a written price before any work is agreed.
Is spray foam a problem if I am selling my Crawley home?
It can be. Many lenders and surveyors are cautious about spray foam, so it often comes up when a buyer's survey is done in Crawley. We remove it by hand, clean the timbers back and give you a Certificate of Removal, before and after photos and a 10-year guarantee to pass to your buyer's surveyor.
Can you board my loft for storage?
Yes. Boards laid straight onto joists crush the insulation underneath. We lay new insulation to 300mm, then fit raised boarding on legs above it. We did this on a 16.5m² loft in Lancing, West Sussex, which you can read in full with photos on our case studies page.
