Looking for non-traditional house insulation in Sandown? We survey homes across Sandown and the PO36 area, then give you a fixed written price before any work starts. Where one half of a pair in Sandown is insulated and the other isn't, we detail the boundary so the neighbour can join later.

Free survey in Sandown
Postcode, service and a phone number is all we need.
What the job covers
- The survey identifies the construction type before anything is specified
- Fixing design depends on the panel or frame behind the wall
- Most system-built homes have thin, cold walls and no fillable cavity
- EWI improves comfort and can renew a tired concrete exterior
Homes and walls in Sandown
We also cover Ryde and Newport (Isle of Wight), close to Sandown. Sandown is about 5 miles from Ryde. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Exposure to wind-driven rain varies across Isle of Wight: 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.
For concrete houses in Sandown, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in England
For a house in Sandown, 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.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
How do I know if my house is non-traditional?
Clues include concrete panels or posts visible at corners, a smooth concrete or rendered finish on houses of a 1940s–1960s estate, steel sheeting on the upper storey, or a mortgage valuation that mentioned the construction type. Common types include Wimpey no-fines (poured concrete), Airey and Cornish Unit (precast reinforced concrete), Reema, Orlit and BISF (steel frame). We identify the type during the survey.

Non-traditional houses in Sandown: 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.
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.
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.
Do you cover Sandown?
Yes — we survey and quote non-traditional house insulation in Sandown (PO36) and nearby Ryde, Newport (Isle of Wight) and Cowes, with a fixed written price before any work starts.
