Wall insulation in Moordown

Finding out what you have. From the pavement, a solid wall and a cavity wall can look the same, especially under pebbledash. The borescope settles it: is there a gap, how wide, is it clean, is it dry, and has it already been filled. On a brick face, a pattern with the short ends of bricks showing every few courses usually means solid wall; all long faces usually means cavity.

Internal wall insulation. On a solid Moordown wall this is usually the answer. We line the coldest rooms one at a time with insulated plasterboard, PIR board such as Celotex or Kingspan bonded to board, or a breathable build-up of wood fibre or mineral wool between battens or a stud, then skim. Where a window reveal is too narrow for thick board, a thin aerogel board keeps the cold bridge away. A room typically takes a few days including the plaster.

The junctions. Reveals, the floor junction, the threshold and joist ends built into a Moordown wall are where cold bridges form if they are skipped. Condensation settles in that cold strip and black mould follows. We treat each one as part of the job.

The thirties houses with an early cavity. By the thirties most Moordown houses were built with a cavity, but a narrow one, tied across with iron ties that rust. If the borescope shows that gap clear, dry and wide enough, a cavity fill of bonded bead or mineral wool is usually worth doing, once the ties have been looked at. A separate cavity wall installer does the fill itself, and you keep their paperwork with the deeds. We say whether your wall suits it and handle the inside: ventilation and making good.

Cladding a painted pebbledash front. A lot of the original dash along Coronation Avenue and Queen Mary Avenue has been painted over more than once, and paint that forms a skin traps water behind it. External wall insulation, board with a render carrier and a thin coat finish, deals with cold bridges at floors and corners in one go. But it means taking that dash off or fixing through it, so we tap the whole wall first. It changes the look, needs a scaffold, and is priced with care.

Air, in a house that used to breathe. A twenties or thirties house dried itself through open fires and draughty sash or casement windows. Lining the walls moves the dew point inward and stops much of that air, so trickle vents, a kitchen and bathroom extract fan and any air brick blocked by a later path all get checked. Skip that and interstitial condensation forms behind the new board. Heat loss falls, and the EPC moves with it, which matters to the many landlords letting houses in Moordown.

One person to ring from the first visit to the last. The quote is itemised, not a figure on the back of a card: the survey and any borescope check, the system and its thickness, making good around windows and doors, ventilation works, and disposal on separate lines, so you can compare it properly against anyone else's.

Nothing is left open or unusable overnight. The site is swept at the end of each day rather than the end of the job, and what comes out leaves with us. If something turns up once we start that nobody could have seen, you get a photograph and a price before we carry on.

Lining a wall inside needs no planning, as the Planning Portal page on insulation says, but it is building control work under regulation 23 and must meet Part L, set out in Approved Document L. External insulation can need planning, as Planning Portal guidance on external walls explains. Moordown has no conservation area; the council keeps the list, and listed buildings need consent.

Ring rather than use the form. Damp patches or black mould appearing on an outside wall after cavity fill or internal lining usually means water is tracking across the cavity, or warm air is reaching a cold surface at a junction.

We look before we take anything out, because the fix depends on which of those it is. If mould keeps coming back on an outside wall, pull furniture a hand's width off it and open the trickle vents until we have seen it. Scheduled work runs Monday to Friday, 8am to 6pm. For anything urgent, ring rather than use the form, and if we cannot pick up we ring you back as soon as we can.

Moordown filled up in the 1920s and 1930s, and that was the period the cavity wall took over from solid brick. Many houses of the early 1920s were still built solid, nine inches of brick with nothing to fill. Many from the 1930s have a cavity, but an early one: often narrow, sometimes with mortar droppings and rubble lying at the bottom, and tied with iron wall ties that can rust.

That is why a doorstep offer of cavity fill for a house here should make you ask questions first. A solid wall cannot be filled at all. A narrow cavity with debris bridging it can let damp across once it is filled, and rusting ties are a repair to deal with before, not after. So have it checked. We use a borescope at more than one point, tell you what the wall actually is, and if it is a cavity that suits a fill, point you to a registered installer. If it is solid, we price internal lining for the rooms that need it most.
