The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
North East · England
Durham is defined by its medieval core, with the cathedral and castle sitting inside a conservation area and a World Heritage setting where many properties are older and more sensitive. Around this centre are Victorian and Edwardian terraces in streets like the Viaduct and Gilesgate, former colliery terraces in surrounding villages, and interwar and post-war semis and modern estates in Neville's Cross, Framwellgate Moor and Belmont. That range means loft work varies a great deal — a historic property near the centre needs a far more careful approach than a 1970s estate house.
We help homeowners across Durham and the surrounding County Durham area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
Durham's older city-centre and terraced homes often have compact, steeply pitched lofts with awkward access over a stairwell and thin, settled insulation, and some sit within the conservation area where changes to the roof are more sensitive. Former colliery terraces in the surrounding area tend to have shallow lofts with tight access. Much of the wider stock is interwar and post-war semi-detached housing in Neville's Cross and Framwellgate Moor, typically carrying ageing wool that suits a top-up, frequently with storage boards laid straight onto the joists. Newer estates toward Belmont usually have some insulation already.
Durham's historic and conservation-area properties call for a careful eye, and the North East's cold, damp winters make ventilation worth close attention. Packing insulation into the eaves of an older terrace can block what little airflow the roof has and encourage condensation, so we keep the eaves clear and treat ventilation and insulation together. On traditional roofs we assess how the covering and any older felt are coping before recommending a build-up.
Cold winters and damp air make condensation and staining common in poorly ventilated Durham lofts, and older traditional roofs can be especially prone. Insulation alone will not cure a moisture problem, so we check the real cause — airflow, a leak or an extractor venting into the loft — before recommending work.
In Durham, cost is driven mainly by loft access on older terraces, the extra care needed on historic or conservation-area roofs, whether old insulation needs removing, and any boarding or ventilation work.
You tell us about your property and what you have noticed in the loft. Nothing is committed at this stage.
We review the property age, roof type, loft access and any existing insulation, moisture or ventilation concerns.
Where required, a survey or assessment is arranged so measurements and conditions can be checked in person.
You receive a clear written recommendation and quotation setting out the scope, materials, price and any guarantee.
Work is completed by The Insulation Company or an approved installation partner, with access protected throughout.
Final checks are carried out, the loft is left clean, and relevant documentation and any guarantee are supplied.
These are examples of our work elsewhere, shown to illustrate what a project involves. They did not necessarily take place in Durham.
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 Durham and nearby County Durham, from Gilesgate and the Viaduct to Neville's Cross, Framwellgate Moor and Belmont, as well as Chester-le-Street, Spennymoor and Bishop Auckland. Request an assessment and we'll confirm coverage for your postcode.
Usually, yes, though older and conservation-area properties call for more care. We assess the roof, keep the eaves clear for airflow and recommend a suitable, sympathetic build-up rather than forcing a standard approach.
Cold, damp winters make ventilation important, and older roofs can be especially prone to condensation. If you have noticed staining or damp, we look at the cause — airflow, a leak or an extractor venting into the loft — because insulation alone will not fix a moisture problem.

Great service with great prices. I felt very comfortable letting them get on with the insulation. No mess was left behind, and it was definitely needed with the horrible weather.

An incredibly professional and efficient service. I can’t fault them in the slightest and would recommend them to anyone looking for this kind of service.
The crew showed up on time, explained everything clearly, finished faster than expected, and we noticed the house felt more comfortable almost immediately.
I was looking at getting my roof insulated but was shocked by the price of some of the quotes I received. I stumbled across these guys and could not be more pleased. Great quality work for a fantastic price.
