Homes and walls in Harrow
We also cover Wembley and Northolt, close to Harrow. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
On brick terraces in Harrow, slips can insulate the wall while keeping the street's look.

Planning and building control in England
For a house in Harrow, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
How is the brick slip system built up?
Insulation boards are fixed as for any EWI, followed by a reinforced base coat. The slips are bonded with the system adhesive, spaced for joints, then pointed. Corners use L-shaped slips so the edge looks like a solid brick.

Brick slip EWI in Harrow: questions
Can I mix brick slips and render?
Yes. A brick plinth or ground floor with render above is a common combination.
Is a brick slip finish more expensive?
Yes — roughly £70–£120 per m² more than render, because of materials and slower installation.
Will brick slips match my neighbours' brick?
We source slips to get close in colour and texture and show samples beforehand, but an exact match to weathered brick isn't always possible.
Do you cover Harrow?
Yes — we survey and quote brick slip finishes in Harrow (HA2) and nearby Wembley, Northolt and Greenford, with a fixed written price before any work starts.
