Local considerations in Harrow
As well as Harrow itself, we quote in Wembley, Northolt and Greenford. 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 older houses in Harrow, stripping old render often reveals mortar repairs that are best done before re-rendering.

Planning and building control in England
Before quoting in Harrow, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
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.
Which new render should I choose?
On older solid walls, breathable lime or a mineral system is often safest. On sound modern masonry, silicone over a mesh base coat gives a durable, low-maintenance finish. If insulation is added, the finish is the one specified for the EWI system.

Re-rendering in Harrow: questions
Do I need building control for re-rendering?
In England and Wales, re-rendering more than half of a wall's area — or more than a quarter of the whole building's envelope — is controlled work under Part L, so usually yes. We explain how it's handled in the quote.
Is it worth adding insulation?
On solid or concrete walls it's usually the most cost-effective time to do it, because access and preparation are already paid for.
How do I know if my render has failed?
Signs include cracks, hollow sound when tapped, bulging, pieces falling off, and damp patches inside behind cracked areas.
Do you cover Harrow?
Yes — we survey and quote re-rendering in Harrow (HA2) and nearby Wembley, Northolt and Greenford, with a fixed written price before any work starts.
