Brentwood is a busy commuter town on the Elizabeth line, with Shenfield, Hutton and Warley around it. Victorian and Edwardian houses sit close to the centre, inter-war and post-war semis fill much of the town, and there are larger detached homes and newer developments on the edges — each with its own kind of loft.
We help homeowners across Brentwood and the surrounding Essex area arrange loft assessments, quotations and installation. Depending on the service, work may be completed by The Insulation Company or an approved installation partner.
Victorian and Edwardian homes near the town centre and in Warley often have older, uneven insulation and lofts that have been altered over time. Inter-war and post-war semis and detached houses in Shenfield and Hutton usually have roomy lofts that suit a top-up or raised boarding, while newer homes tend to have insulation already, so the question becomes whether more depth, boarding or ventilation is worthwhile.
Larger family homes often have lofts that have been extended, part-boarded or partly converted, leaving gaps and uneven depth in between. We look at the whole roof space, keep the eaves clear for airflow and plan any boarding so storage sits above a full depth of insulation.
Lofts with blocked eaves, or extractor fans venting into the roof space, can suffer from condensation. Insulation alone will not cure a moisture problem, so we check the actual cause — airflow, a leak or an extractor venting into the loft — before recommending work.
Head out of the centre towards Pilgrims Hatch, Doddinghurst, Kelvedon Hatch and Ingrave and you find plenty of bungalows and chalet-style homes. A bungalow has a big loft for the size of the house, because every room sits under the roof. That makes the insulation up there more important, not less. In older bungalows we often find thin fibreglass that has been flattened by years of storage, with boards laid straight on top and the eaves stuffed shut.
Chalet homes with rooms in the roof are different again. The main loft is often small, and the cold spots are the low spaces behind the knee walls and the sloping ceilings. We check each of those areas on the survey, not just the part you can reach from the hatch.
In October we replaced the insulation in a 70m² bungalow loft in Ingatestone, about five miles from Brentwood. The old insulation was under 100mm deep and there was no roof ventilation at all. We removed the old insulation, treated the timbers, fitted lap vents and laid a new 300mm layer in a single day. Many Brentwood bungalows are built the same way, so it is a good guide to what the work can involve. If you are not sure whether your loft needs a top-up or a full replacement, our guide on signs your loft insulation needs replacing is a good place to start. Further up the A12, see our Chelmsford page.
In Brentwood, cost is driven mainly by the size and layout of the loft, whether old insulation needs removing, access and any boarding or ventilation work. Larger detached lofts need more material, while period homes can take more preparation.
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.
The Ingatestone bungalow is a recent job of ours, about five miles from Brentwood. The others are examples of our work elsewhere, shown to illustrate what a project involves.
Under 100mm of flattened insulation and no roof ventilation in a 70m² bungalow loft. Old insulation removed, timbers treated, lap vents fitted and new 300mm insulation laid in a day.
Ingatestone, Essex
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.
Example from our project library
Emma's upstairs warmed slowly and the landing felt cold. We topped the floor to 300mm, added SF19 SuperFOIL across the 46m² roof pitch and retained a 7m² T-shaped access platform around the hatch.
Cardiff
Julie's upstairs rooms felt noticeably colder than the ground floor and lost their heat quickly once the heating went off. By insulating both the loft floor and the roof pitch — and adding a boarded storage area — we gave the whole loft a consistent, well-sealed insulation layer, so the bedrooms hold their warmth for longer and feel more comfortable on cold evenings.

Sheffield
A survey flagged the insulation while the sale was going through. We topped up the full 120m² bungalow loft within the week of the survey so the sale was not held up.
Winchester
Andrew used his loft regularly and wanted to keep the wide boarded platform while fixing the cold roof. We fitted SF19 SuperFOIL around the central truss work across the 54m² pitch, retaining 14m² of boarding.
Sheffield
Andrew's low-roof loft was draughty in windy weather, with awkward bracing that had left previous attempts incomplete. We cut 300mm of Knauf glass mineral wool accurately around the braces and wiring.

Raised loft boarding lets you keep a large storage area while the insulation underneath stays at full depth. We will suggest a layout that suits how you use the loft.
Usually, yes. We look at the unconverted areas, including the spaces behind knee walls and over extensions, and recommend how to bring them up to a sensible depth without blocking ventilation.
Yes. Bungalows are common around Pilgrims Hatch, Doddinghurst and Ingrave, and their lofts are large for the size of the house. We check the depth and condition of what is there, the eaves ventilation and any boarding, then recommend a top-up or a full replacement.

Customer feedback
Feedback from customers who have used our insulation services.
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.
Top man Leonardo with the insulation. Did the insulation in a day.
Excellent workmanship. Work completed in a clean and tidy manner.
Lovely crew. They arrived on time and gave me an excellent quote. A friendly group of workers who kept me updated throughout the process.
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.
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.
