Loft Insulation in Caerphilly
Caerphilly's post-war estates usually have roomy, straightforward lofts where a mineral wool top-up to 270mm makes a real difference to how warm the house feels.

Loft Insulation in Caerphilly
Cardiff Insulation Company fits loft insulation in Caerphilly and the surrounding CF83 villages. We're just over the mountain from Cardiff, so getting to you for a survey is quick, and most standard jobs are completed in a single day.
Caerphilly's older homes sit in a wet, hilly part of South Wales, and their lofts often show it. Alongside insulating, we deal with the problems we regularly find in valley roof spaces: damp timbers, mould, and spray foam that was applied to the underside of the roof in the hope of stopping leaks.

Caerphilly homes and their lofts
Around the castle and the older parts of town you'll find terraced streets from the late Victorian and Edwardian period, many built in local stone and stepping up the hillsides. These houses typically have shallow lofts, small hatches and party walls shared with neighbours. Insulation, where there is any, is often thin and patchy.
Caerphilly also expanded a great deal after the war, with large estates of semis and terraces and, later, private estates of family homes on the edges of town. Those lofts are more uniform and easier to work in. In both, the weather is a factor: the valleys get a lot of rain, and roofs facing the prevailing wind take a pounding, so we pay close attention to ventilation and the condition of the timbers.
What Caerphilly homes usually need
Spray Foam Removal in Caerphilly
Some older valley homes had spray foam put on the roof underside to hold slipped slates in place, and we remove it, clean the timbers and re-insulate properly.

Loft Mould Treatment in Caerphilly
Heavy rainfall and cold hillside roofs mean condensation and mould are common here, so we treat the timbers and sort the ventilation that caused it.
View serviceHills, rain and terraced streets
Many of Caerphilly's terraces are on steep, narrow streets, so we plan van parking and carrying routes before the day. Valley weather means we always check the underside of the roof for leaks and mould before laying anything new; insulation over a wet problem only hides it.
If your loft has been sprayed with foam, it's worth knowing that many surveyors and mortgage lenders now flag it during a sale. Our spray foam removal guide explains why, and our spray foam removal service covers the job from start to finish.
Loft insulation in Caerphilly: FAQs
Is spray foam in my Caerphilly loft a problem?
It can be. Spray foam was sold to some homeowners as a way to stop leaks or hold loose slates, but it can trap moisture against the roof timbers and hide rot. Many surveyors and lenders now raise it when a house is sold. We can inspect it, explain what we find, and if removal makes sense, cut it away, clean the timbers and re-insulate with breathable materials.
My terraced house shares a loft space with next door. Can you still insulate it?
Usually, yes. In most terraces the party wall runs up to the roof, but in some older houses it stops short or has gaps. We insulate your side only and can point out any openings into the neighbouring loft, which matter for fire separation, sound and pests. If the party wall needs building up, we'll tell you so you can get the right tradesperson.
Does the wet valley weather affect loft insulation?
The insulation itself isn't harmed by the climate, but damp roofs are. If slates are slipping or felt has failed, water can soak into insulation and stop it working. Before we fit anything, we check for leaks and staining. If there's a roofing issue, we'll recommend getting it fixed first so your new insulation stays dry.
