The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.
London · England
Hounslow sits in west London along the old Great West Road, its character shaped by the railway, the arterial roads and the closeness of Heathrow. Victorian and Edwardian terraces fill the older parts of Hounslow itself, while Heston, Cranford and Whitton carry sweeping interwar semi-detached estates built as the suburbs pushed west. Post-war housing and newer apartment developments add to the mix, and the borough's density and diversity mean loft work ranges from tight terrace roofs to wide 1930s voids — often altered, boarded or part-converted somewhere along the way.
We help homeowners across Hounslow and the surrounding west-London 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 interwar semis of Heston, Whitton and Cranford usually have thin original insulation that has settled over the decades, making a top-up worthwhile, and many carry storage boards laid straight onto the joists. The Victorian and Edwardian terraces around Hounslow town and the fringes of Isleworth tend to have compact lofts with steep, awkward access and insulation that has compressed unevenly. Under the Heathrow flight paths, some homes have had roof works or conversions over the years, so what is actually in the loft varies house to house and is best judged on inspection.
Hounslow's older terraces and interwar roofs predate modern ventilation standards, so blocking the eaves with insulation can invite condensation — we keep airflow in mind alongside depth. Part-converted lofts are common where families have added storage or a room, so we check whether it is a loft floor to insulate at joist level or a room-in-roof needing rafter-level work. Boarded-over hatches frequently conceal compressed wool that is no longer performing.
Poorly ventilated Hounslow lofts often show condensation, especially where a bathroom or kitchen extractor vents into the roof space. We find the underlying cause rather than assuming more insulation will fix it.
Access and parking on busy terraced streets, the condition and depth of any existing insulation, the roof area of larger semis, and any removal, boarding or ventilation work are the main things shaping a Hounslow quotation.
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 Hounslow.
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 the borough, from Hounslow town and Isleworth to Heston, Cranford and Whitton. Request an assessment and we'll confirm coverage for your postcode.
It doesn't change how insulation is installed, but many homes near the flight paths have had roof works or acoustic upgrades over the years, so we always check what is genuinely in the loft and whether ventilation has been affected before recommending a build-up.
Sometimes, but not always. Condensation usually points to a ventilation or moisture problem — often an extractor vented into the roof space — so we identify the cause first rather than assuming insulation alone is the cure.
Customer feedback
Feedback from customers who have used our insulation services.
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.
Smooth and stress-free process. The team were polite, efficient and did a great job. Really pleased with the results. Thanks guys!
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.
