Insulation in Guisborough
Insulation across Guisborough's TS14 postcode: loft insulation £400 to £800, cavity wall fill £700 to £1,200, internal wall insulation £4,000 to £8,000 for the solid-stone cottages. Market-town housing surveyed for what it actually is, not what it looks like.
Cottages and estates
Guisborough splits in two. The older core, stone and solid-brick cottages around Westgate and the Market Cross, has no cavities, thick walls that stay cold until March, and lofts under steep roofs: internal wall insulation (£4,000 to £8,000) with breathable build-ups, plus loft work adapted to the roof geometry. The 1970s and 80s estates, Belmangate, Hutton and the Avenue, are standard cavity-fill and loft-top-up territory: £700 to £1,200 and £250 to £450 respectively.
Stone walls: respect the material
Stone cottages manage moisture differently to brick, and Guisborough's older stock needs vapour-open internal insulation, never sealed foam systems that trap damp in the wall core. Surveys on the older streets include moisture readings as a matter of course.
Edge-of-moors exposure
Sitting under the North York Moors escarpment, Guisborough takes colder winters and more driving weather than the coast-to-estate average. That raises both the payback on insulation and the importance of getting cavity-fill suitability surveyed rather than assumed.
