What we look for in Boston
Surveys in Boston also cover the surrounding PE21 district and towns such as Spalding and Skegness. Boston sits around 27 miles from Lincoln. Housing in the East Midlands includes Victorian terraces in the towns and cities, plenty of inter-war semis and post-war council estates, some of them system-built.
Much of Lincolnshire 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.
We plan internal insulation in Boston homes room by room so you keep the rest of the house usable.

England: planning and regulations
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Boston: questions
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
Do you cover Boston?
Yes — we survey and quote internal wall insulation in Boston (PE21) and nearby Spalding, Skegness and Wisbech, with a fixed written price before any work starts.
