The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
East Midlands · England
Grantham is a Lincolnshire market town with a long history, from its medieval church and coaching inns to its Victorian engineering works. Its older core includes stone-built and traditional properties, some listed, alongside Victorian and Edwardian terraces near the centre and the railway. Interwar and post-war semis spread through the suburbs and out toward Barrowby and Great Gonerby. That range means loft work here varies from careful, breathable work on older traditional roofs to a straightforward top-up on a 1930s semi with sound existing wool.
We help homeowners across Grantham and the surrounding East Midlands 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 Victorian terraces around Grantham's centre often have compact lofts with awkward access and insulation that has settled over many years. Interwar and post-war semis in the suburbs typically carry thin original wool suited to a top-up, frequently with storage boards laid straight onto the joists. Older stone and traditional properties, including some listed buildings, need a more careful, breathable approach, since the wrong materials can trap moisture in walls and roofs that were designed to breathe. Newer estate homes on the edges usually have some insulation already.
In Grantham's older stone and traditional buildings, breathability matters: sealing a traditional roof too tightly with modern materials can drive moisture into the structure, so we take a careful, considered approach on these homes. On the Victorian terraces and semis, we keep the eaves clear so airflow is not blocked when insulation is added. Ventilation and moisture are assessed alongside insulation depth rather than treated as an afterthought.
Condensation and damp complaints are common in poorly ventilated Grantham lofts, and older traditional roofs are especially sensitive to trapped moisture. Insulation alone will not cure a damp problem, so we identify the real cause — airflow, a leak or an extractor venting into the loft — before recommending work.
In Grantham, cost is driven mainly by loft access, whether old insulation needs removing, and the care needed on older or listed roofs where breathable materials and a gentler method may be appropriate. Boarding and ventilation work also affect the price.
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 Grantham.
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 Grantham and the surrounding East Midlands, from the town-centre terraces and traditional core to the interwar and post-war suburbs, as well as Barrowby, Great Gonerby and Bottesford. Request an assessment and we'll confirm coverage for your postcode.
Often, yes, but traditional stone and listed buildings need a careful, breathable approach so moisture is not trapped in structures built to breathe. We assess the roof and recommend suitable materials and methods rather than a standard modern build-up.
If you have noticed condensation or staining, it is worth checking, especially in older roofs sensitive to trapped moisture. We look at the cause — airflow, a leak or an extractor venting into the loft — because insulation alone will not fix a moisture problem.
Customer feedback
Feedback from customers who have used our insulation services.
Very good, prompt and friendly service with an excellent result. Very pleased with the outcome. Well done lads.
Recommended. Friendly, efficient and did a great job in two very dirty loft spaces. All the waste shifted quickly. Top job. Thanks.
These guys are the best! Rory and Leo were very kind to me and got it all done in just a day. Thank you.
Jake and Rory supplied and fitted the insulation in our loft. They did an excellent job and I would recommend them.
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.
