- Steel-framed BISF houses need care around the upper-storey cladding
Local considerations in Yeovil
As well as Yeovil itself, we quote in Bridport, Dorchester and Bridgwater. It's roughly 32 miles from Yeovil to Bath, the largest town in Somerset. 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 Somerset: 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 one half of a pair in Yeovil is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Planning and building control in England
For a house in Yeovil, 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.
Does EWI fix mortgage problems with PRC houses?
Not on its own. Some precast reinforced concrete (PRC) house types were designated defective, and many lenders want a certified structural repair before they will lend. Insulation and render over the outside is not that repair. Other types, such as Wimpey no-fines, are generally treated differently. If mortgageability matters, speak to your lender or a surveyor before booking any work.

Non-traditional houses in Yeovil: questions
Can you put EWI on a BISF house?
Yes, with care. The steel frame and upper-storey cladding need a system and fixing method designed for that construction, and the condition of the frame should be understood first.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
What if my neighbour isn't insulating?
We finish the system neatly at the boundary with a closing detail so the neighbouring house isn't affected and can be joined later.
Do you cover Yeovil?
Yes — we survey and quote non-traditional house insulation in Yeovil (BA20) and nearby Bridport, Dorchester and Bridgwater, with a fixed written price before any work starts.
