The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
South West · England
Plymouth's housing was shaped by the Second World War: heavy bombing flattened much of the centre, and the post-war rebuild produced extensive estates and terraces across the city, from the reconstructed centre to Efford, Whitleigh and Ernesettle. Surviving Victorian and Edwardian terraces cluster in Stoke and Mutley, interwar semis ring the older suburbs, and naval and dockyard housing reflects the city's maritime role. That mix means loft work is rarely one job — a 1950s rebuilt semi behaves quite differently from an older terrace or a modern estate house near the edge.
We help homeowners across Plymouth and the surrounding South West area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
Much of Plymouth's stock is post-war rebuild — semis and terraces across Efford, Whitleigh, Ernesettle and Ham — typically carrying thin original wool that suits a top-up, frequently with storage boards laid straight onto the joists. The older terraces of Stoke and Mutley often have compact lofts with awkward access and settled insulation. Exposed properties near the Sound and the coast take a share of salt air and weather, so airflow and moisture matter here too. Newer homes toward Plympton and Plymstock usually have some insulation already, so the question is whether more, boarding, or better ventilation adds value.
Plymouth's coastal, high-rainfall climate makes ventilation and moisture worth close attention, especially on properties exposed to weather off the Sound. Packing insulation hard into the eaves can block airflow and encourage condensation, so we keep the eaves clear and treat ventilation and insulation together. On post-war roofs we also check the condition of the covering and any original felt before recommending a build-up.
Plymouth's coastal position and high rainfall make condensation and damp complaints common in poorly ventilated lofts. Insulation alone will not cure a moisture problem, so we look for the actual cause — airflow, wind-driven rain, a leak or an extractor venting into the loft — before recommending work.
In Plymouth, cost is driven mainly by loft access, whether old insulation needs removing, the exposure of the roof, and any boarding or ventilation work. Parking and access on terraced and estate streets can also be a factor.
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 Plymouth.
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 Plymouth and the surrounding area, from Stoke, Mutley and the city centre to Efford, Whitleigh and Ernesettle, as well as Plympton, Plymstock and Saltash. Request an assessment and we'll confirm coverage for your postcode.
Usually, yes. Post-war Plymouth houses often carry thin original wool that has settled, and a top-up to a modern depth can make a real difference. We check the existing insulation, keep the eaves clear for airflow and recommend a suitable build-up.
Plymouth's coastal, wet climate makes ventilation important. If you have noticed condensation or staining, we look at the cause — airflow, wind-driven rain, 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.
These guys were the nicest and provided the best service. They did the job much quicker than expected. Very happy with the job and the price. Highly recommend.
The boys were very kind and well advised. They got the job done quickly and smoothly. My loft was in pretty bad shape, as I have a slight hoarding problem, and they passed no judgement. Thank you for your service.
Very good, prompt and friendly service with an excellent result. Very pleased with the outcome. Well done lads.
