The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
South East · England
Guildford sits in a gap through the North Downs, and its housing steps from a historic centre out into leafy suburbs. The old town holds period cottages and a good deal of conservation-area property, Victorian and Edwardian terraces run through areas like Charlotteville and the streets near the station, and the suburbs of Merrow, Burpham and Onslow Village fill out with interwar and post-war semis. Newer estates continue toward the town's edges. That spread means a loft here could be an old, irregular period roof or a straightforward modern one.
We help homeowners across Guildford and the surrounding Surrey 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 period cottages and older houses in and around the town centre often have shallow, irregular lofts, traditional roof construction and awkward access, all of which call for a careful, breathable approach. The Victorian terraces of Charlotteville and the station area typically have compact lofts with thin, settled original insulation. The interwar and post-war semis of Merrow, Burpham and Onslow Village are more conventional, usually suiting a top-up over sound existing wool, and boards are often laid straight onto the joists for storage. Modern estate homes toward the edges tend to already meet a reasonable standard.
Guildford's mix of protected period property and its position among the Downs and the Wey valley both shape the work. In older and conservation-area houses we favour breathable materials, keep the eaves clear so a traditional roof can breathe, and check whether any consents apply before a build-up. In the suburban semis and modern homes the focus shifts to the condition of existing insulation and whether ventilation and boarding would add more than extra depth.
The Wey valley and generally damp local air mean condensation is common in poorly ventilated Guildford lofts, particularly in older roofs. Insulation alone will not fix a moisture problem, so we check the cause — airflow, a leak or an extractor venting into the loft — before advising work.
In Guildford, cost is driven mainly by loft access and roof type — older period roofs being more involved than modern ones — whether old insulation needs removing, and any boarding or ventilation work. Access in the historic centre can add to a job.
Many Guildford 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 Guildford.
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 Guildford and nearby Surrey, from the town centre and Charlotteville to Merrow, Burpham and Onslow Village, as well as Godalming, Shalford and Merrow. Request an assessment and we'll confirm coverage for your postcode.
Usually yes, but older cottages often have shallow, irregular lofts and traditional roofs that need a breathable, careful approach. We assess the space, keep the eaves clear for airflow, and if the property is listed or in a conservation area we check whether any consents apply.
It depends on its condition. Sound, dry existing wool can usually be topped up, but if it is damp, contaminated or badly compressed, removal and a fresh install is the better route. We assess it before advising.
