The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
South East · England
Horsham is a busy West Sussex market town with an old core around The Causeway and the Carfax, where timber-framed and Georgian buildings survive, and a Victorian and Edwardian belt around the centre. Its real growth, though, has been more recent: large interwar and post-war estates, extensive later development, and modern new-build neighbourhoods such as Broadbridge Heath and land toward Southwater. That spread from period cottages to brand-new homes means loft work here ranges from delicate older roofs to straightforward modern top-ups and boarding.
We help homeowners across Horsham 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 older properties near The Causeway and the Carfax often have steep, compact period lofts with awkward access and settled insulation. The Victorian and Edwardian terraces around the town centre tend to carry thin original material that suits a top-up. Interwar and post-war semis across Roffey and Littlehaven usually have older wool that has compressed over time, frequently with boards laid straight onto the joists. Newer homes at Broadbridge Heath and around Southwater generally meet recent standards, so raised boarding or improved ventilation is often more useful there than adding depth.
Across Horsham's mix of ages, the sensible starting point varies. Older roofs need airflow kept clear at the eaves so they can breathe, while on newer estates the priority is usually lifting boarding above a proper depth of insulation rather than crushing it for storage. On every property we check that bathroom and kitchen extractors vent outside rather than into the loft, since that is a frequent and avoidable cause of condensation whatever the age of the house.
Condensation in Horsham lofts is often caused by poor ventilation or an extractor discharging into the roof space rather than a leak. Insulation alone will not resolve a moisture problem, so we identify the actual cause before recommending work.
In Horsham, cost is driven mainly by the age and access of the roof, whether existing boarding or old insulation needs lifting or removing, the depth of top-up required, and any boarding or ventilation work.
Many Horsham 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 Horsham.
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 Horsham and nearby West Sussex, from the town centre and Roffey to Littlehaven, Broadbridge Heath and Southwater, as well as Billingshurst, Storrington and Cranleigh. Request an assessment and we'll confirm coverage for your postcode.
It depends on what is already there. Many newer homes at Broadbridge Heath and around Southwater meet recent standards, so raised boarding above the insulation or better ventilation often adds more than extra depth. We assess before recommending.
Condensation is often caused by poor airflow or an extractor venting into the roof space. If you have noticed staining, we look at the cause first, because insulation alone will not fix a moisture problem.
Customer feedback
Feedback from customers who have used our insulation services.
It was refreshing to have two young lads who came in and worked incredibly hard on my loft. They came early and left late to get the job done. The best workers I’ve had in a long time, and I would recommend them 100%.
Good lads. They were professional throughout, took extra care and left the place spotless. We can already feel the difference with the fresh insulation.
Top man Leonardo with the insulation. Did the insulation in a day.
Excellent workmanship. Work completed in a clean and tidy manner.
