The Insulation Company helps homeowners arrange loft-insulation assessments, quotations and installation services across the UK.

Harwich is a historic port town on the estuary of the Stour and Orwell, with the narrow streets of Old Harwich, the Victorian seaside town of Dovercourt and post-war estates beyond. Its coastal position and mix of old and newer homes mean loft work here often comes down to dealing with weather and ventilation as well as depth.
We help homeowners across Harwich 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.
Old Harwich has many period and listed buildings with irregular roofs and very little insulation. Dovercourt has a lot of Victorian and Edwardian terraces and villas whose lofts often have old, uneven insulation, while post-war and later homes around the town usually have simpler lofts that suit a top-up or raised boarding.
Being on the coast, Harwich homes take the full force of wind-driven rain off the North Sea. We check the roof for signs of water getting in before adding insulation, keep the eaves clear so the loft can breathe, and make sure the insulation is fitted so wind cannot blow through it.
Exposed coastal roofs, and lofts where insulation has been pushed into the eaves, can suffer from damp and 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.
In Harwich, cost is driven mainly by the age and layout of the house, loft access, whether old or damp insulation needs removing and any boarding or ventilation work. Period homes in Old Harwich can take more preparation than post-war houses.
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 Harwich.
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.

Not on its own. On the coast, damp can come from wind-driven rain getting through the roof or from poor ventilation. We find the cause first, then recommend insulation that will not make the problem worse.
Yes. We check the existing insulation, the party walls and the eaves, then bring the loft up to a sensible depth while keeping airflow clear.

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.
