What you get

- Most system-built homes have thin, cold walls and no fillable cavity
- EWI is not a structural repair for PRC houses designated defective
- EWI improves comfort and can renew a tired concrete exterior
Before we quote in Havant
We also cover Waterlooville and Portsmouth, close to Havant. It's roughly 19 miles from Havant to Southampton, the largest town in Hampshire. 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 Hampshire: 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 Havant, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in England
Planning in Havant follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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.
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 Havant: 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 Havant?
Yes — we survey and quote non-traditional house insulation in Havant (PO9) and nearby Waterlooville, Portsmouth and Gosport, with a fixed written price before any work starts.
