Cold Rooms, Black Mould, Rising Bills?
Older solid-wall homes around Walsall lose heat fast. Cold wall surfaces cause condensation and black mould — especially in winter. At aPlastering – Walsall Plastering & Internal Wall Insulation, we install Internal Wall Insulation that adds a thermal layer inside external walls, keeping heat in, stopping cold spots, and making your rooms feel cosy again.
Why Solid Walls Lose So Much Heat
Many older Walsall homes were built with solid brick walls and no cavity. These walls are strong but conduct heat very quickly. Even with good windows and loft insulation, up to around a third of your home’s heat can still escape through cold external walls.
Internal wall insulation adds a new thermal layer on the inside of those walls, so the surface stays warmer, reduces condensation, and keeps more heat in your rooms.
What Is Internal Wall Insulation (IWI)?
Internal wall insulation basically means adding insulation to the inside of your cold external walls. Instead of doing it from outside the house, everything is done from the inside. We fix insulation boards to the wall, tidy up all the surfaces, then plaster it so the room looks completely fresh again — the only difference is it stays much warmer, stops the damp patches, and cuts the drafts. Once it’s finished, you wouldn’t even know work was done — it just feels more comfortable.
Problems We Solve in Walsall Homes
Many homes in Walsall have the same problems — cold rooms, condensation, damp patches and black mould. These issues are common in older solid-wall homes and bay windows where heat escapes quickly.
Common signs you need internal wall insulation:
– Cold external walls
– Cold spots around bay windows and corners
– Morning condensation
– Black mould
– Rooms that never stay warm
– One bedroom colder than the rest
– Musty smells or damp patches
These problems happen because solid walls have no insulation, allowing cold to pass straight through the brickwork.
Internal wall insulation warms the walls, stops condensation, prevents mould returning and makes your home warmer and more energy-efficient.
Materials We Use
We’ll guide you through the choices and help you find the insulation option that’s right for your home. Our aim is to make everything simple and stress-free, giving you the best results with as little disruption as possible — so you don’t have to worry about a thing.
