What we look for in Salisbury
As well as Salisbury itself, we quote in Andover, Totton and Southampton. It's roughly 34 miles from Salisbury to Swindon, the largest town in Wiltshire. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Wiltshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
Where eaves are shallow on a house in Salisbury, grey EPS can sometimes avoid the cost of extending the roofline.

England: planning and regulations
Before quoting in Salisbury, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
How thick does the board need to be?
On a 225mm solid brick wall, around 90mm of grey EPS or 100–110mm of white EPS typically gets close to 0.30 W/m²K. Stone walls, concrete panels and hollow-block walls start from different points, so the system supplier's calculation for your wall sets the final thickness.

EPS insulation in Salisbury: questions
How long does EPS last on a wall?
The board itself doesn't degrade when protected by the render system. Service life depends on the render, sealants and detailing, typically 25–30 years or more with maintenance.
Will woodpeckers damage EPS?
It happens occasionally, especially near woodland. Damage is to the render and board surface and is repaired with a mesh patch and colour-matched finish.
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
