Internal wall insulation in Cannock.

What kind of homes are common in Cannock?

Cannock Chase's housing follows its mining history. Hednesford grew rapidly in the second half of the 19th century as pits opened, and many houses in Heath Hayes and Norton Canes were built between about 1890 and 1914 for mining families.

Between the wars, council estates were built at places such as Pye Green and Green Heath, and more estates followed after the Second World War. So a Cannock street might be solid-walled terraces, early semis or later cavity-walled homes, sometimes within a short walk of each other.

Why do older Cannock terraces feel so cold?

Mainly because a single thickness of solid brick lets heat through far more easily than a modern insulated wall. The inside surface stays cold, and cold surfaces make you feel cold even when the air is warm.

End-of-terrace houses have it worse, with a whole gable wall exposed. Rear kitchens and bathrooms in back additions are another common problem, with several outside walls and a lot of steam.

A suitable internal wall insulation system addresses the wall itself. See the main internal wall insulation page for how the systems compare.

What causes mould on the gable wall of an end terrace?

Usually a cold, exposed wall combined with everyday moisture. The gable catches more weather and loses more heat, so its inside face is often the coldest surface in the house. Condensation collects there first, then mould follows, often behind wardrobes or beds.

Before insulating, I check the gable for rain getting in: failed pointing, blocked gutters or cracked render. Those are repairs first. Then insulation warms the surface and ventilation improvements, organised with trusted trades, deal with the moisture.

More on this in my condensation and black mould service and the guide to stopping mould.

My house has had damp treatments before. Does that matter?

Yes, and it is worth telling me at the visit. Many older homes have been through rounds of damp treatment over the years: injected damp-proof courses, sand and cement render on the inside, or waterproof paints.

Some of those can trap moisture in a solid wall rather than let it dry, and that affects which insulation is safe to fit. I check for:

• Hard cement render or gypsum plaster at the base of walls.
• Raised ground or paths outside that sit above the floor level.
• Salt staining and crumbling plaster low down on the wall.
• Signs of rain penetration on exposed walls.

Where there is a moisture source, that gets dealt with first. Then the insulation system is chosen to suit what is left: often a vapour-open build-up with lime on older Cannock terraces, sometimes PIR where the wall is dry and space is tight.

If the old treatments have left tired or blown plaster elsewhere in the house, I can put that right too. See plastering.

What about post-war homes in Cannock?

Most post-war houses have cavity walls, where internal insulation is rarely the first step. Some post-war estates across the region were also built with non-traditional systems, such as concrete panels or steel frames, which need specialist advice.

If your home is one of these, I will say so at the visit and explain what I can and cannot help with. Cold bays, tile-hung panels and mouldy rooms can still be improved in the right way.

Can I insulate my Cannock home one room at a time?

Yes, and most people do. Starting with the coldest bedroom or the mouldiest room spreads the cost and keeps the disruption small. The best long-term result still comes from insulating the whole house, including the loft and floors, so I recommend planning for that in the near future.

I plan the first room with the rest of the house in mind, so later rooms join up without leaving cold strips where insulated and uninsulated walls meet. You keep the written recommendation for the whole house, which makes the next phase simple to book, whether that is next spring or in a few years.

How does a Cannock job run?

Cannock is usually about 20 minutes up the A34 from my base in Walsall, so visits are easy to arrange. I also cover Hednesford, Heath Hayes, Norton Canes, Huntington and Great Wyrley.

The process is simple: free home visit, written quote, protected and tidy site, room ready to decorate, handover and a follow-up call about four weeks later. Internal insulation does not normally need planning permission; listed buildings need listed building consent.
