Internal Wall Insulation Sutton Coldfield
Cold rooms in a home that should feel warm and cosy?
High energy bills, yet your house still feels uncomfortable?
That constant frustration with a home you should love?
We fix the problem at its source with internal wall insulation designed for solid brick homes.
Cold Walls, Damp and High Heating Bills?
Many homes across Sutton Coldfield — especially 1930s semis, terraces and older properties — were built with solid brick walls and no insulation.
That often leads to:
- cold external walls that never warm up
- condensation forming behind furniture
- black mould in corners and around windows
- high heating bills with little comfort
If your home still feels cold even with the heating on, the problem isn’t the heating — it’s heat escaping through your walls.
Truster by Homeowners
"Brilliant service from Aplastering. They installed internal wall insulation (IWI) and plastered two bedrooms in our house, which was previously freezing cold. The difference is unbelievable - the rooms are now much warmer and far more comfortable...
"A professional service from start to finish with some great advice, turned up on time and completed the plastering of the bedroom, stairs and landing to a very high standard, will definitely be using them for future projects..."
"We had our house insulated recently and the difference is honestly amazing. Before, it used to take forever to warm the house up, we’d got to the point where we were even talking about selling because it was just that cold. Now it’s so warm and cosy, it’s a massive change..."
Designed for Warm, Comfortable Living
Solid walls are usually made from dense brick, stone, or masonry — strong materials, but poor at keeping heat in. Because they have high thermal conductivity, heat from your home escapes straight through the wall, leaving the inside surface cold. When warm air hits that cold surface, it cools and forms condensation, which can lead to damp patches and black mould. This is why homes with solid walls feel cold and expensive to heat — they simply lose heat much faster than modern insulated walls
Built on Experience, Designed for Real Homes
We install insulation on the inside of your external walls, creating a thermal barrier that keeps heat inside your home.
Once installed and plastered:
- Warmer rooms with no cold wall effect
- Reduced condensation and mould risk
- Lower heat loss and improved efficiency
- A more comfortable, healthier home
- Smooth, clean plastered finish ready to decorate
- Reduced heating bills
From the outside, nothing changes — but inside, the difference is immediate.
