Rendering and external wall insulation across Greater London and beyond

Our work is centred on London, but it does not stop at the boundary. We cover the outer boroughs and the towns just beyond them in Hertfordshire, Essex, Surrey and Buckinghamshire, for houses, bungalows and new builds alike.

Bungalows and outer-London houses

Out towards the edge of London and beyond, the housing changes again: more detached homes, more bungalows, and more render that was applied directly to the wall decades ago and has now started to let go. Once render loses its bond it comes away in sheets, and whatever is behind it gets wet.

On this Hertfordshire bungalow the old render had failed along the base of the wall. We stripped it back, fixed insulation boards and finished the whole house in a new render system.

The finished result

The same bungalow finished, with the curved bays and the base detail carried through, and the whole house under one consistent finish.

New builds too

We also render on new builds, working alongside the main contractor. On this Brentwood development we rendered the feature piers and panels between the brickwork, where crisp edges and straight lines are the whole point.

How a job runs

A surveyor visits, looks at the whole elevation and checks the wall build-up, damp risks, access and the planning position for your address. You get an itemised written quote that separates preparation, the system or repair proposed, detailing around windows and sills, and scaffolding. On site the preparation is done first and properly, each coat is given its curing time, and the job ends with inspection, sign-off and warranty paperwork.

Greater London and surrounding areas questions

Do you work outside London?

Yes, in the counties around it. We also work in Hertfordshire, Essex, Surrey and Buckinghamshire, including towns such as Potters Bar, Watford, Brentwood, Loughton, Epsom, Esher, Woking, Guildford, Gerrards Cross, Beaconsfield, Amersham and High Wycombe. Send your postcode and we will confirm.

Do you cover Surrey and Buckinghamshire?

Yes. Surrey and Buckinghamshire have many older detached and semi-detached houses, often with solid walls or render that is decades old, which is exactly the work we do. We survey and quote the same way as in London: a free visit, then a written quote with no pressure.

Can you insulate a bungalow?

Often, yes. Bungalows have a lot of exposed wall for their size, and many are solid-wall or have render that has started to fail. We check the wall, the base detail and the eaves at survey before recommending a system.

Do you work for developers and main contractors?

Yes. Alongside homeowners, we render on new-build developments and blocks, working to the contractor's programme, access and specification.
