A house in Hangersley may be solid wall, cavity or timber frame, and only a borescope tells you whether a fill is safe, so each wall is checked before any price. Four in ten homes around Hangersley are detached, a lot of them built one at a time on their own plot, and that means no two walls on the same lane are necessarily the same construction. There is no typical house here to quote from, so we survey each elevation on its own before anybody puts a price on a wall.
The usual problems in Hangersley are a cold room in a house nobody has ever fully surveyed, damp appearing on an inside wall after driven rain, and owners who have been quoted for a whole house fill and want to know whether that even makes sense on their building.
We measure the wall thickness at each elevation, borescope anything that could be a cavity, and write it up as a free itemised quote in which every wall is a separate line. If two walls need two different answers, you will see that on the page. The loft is covered on insulation in Hangersley.
The work
Every elevation surveyed on its own

Working out the construction, wall by wall. Thickness at a reveal, the brick bond, and a borescope through one drilled hole wherever a cavity is possible. A one off house extended twice over fifty years can have nine inch solid brick on the original, brick and block cavity on one addition and a timber frame with a brick skin on another. Each of those wants a different answer and only one of them can be filled at all.
Timber frame, which catches people out. A Hangersley timber frame house with a brick outer skin looks exactly like a cavity wall from the pavement, and the gap behind the brickwork is a ventilated drainage cavity that must stay clear. Filling it is a serious mistake. The camera shows the breather membrane and the studs in minutes, which is why we never quote from the outside.
Cavity fill where the wall takes it. Clear and dry masonry cavity, and it takes bonded polystyrene bead or blown mineral wool, drilled on a pattern, injected under control, eaves and every reveal closed off first and the holes made good. It cuts the heat loss through that wall sharply and the payback is short. A fill is normally covered by an independent scheme run separately from the installer.
Failed and slumped fill. Older fills in Hangersley settle. The camera finds an empty band at the top of the wall and a compacted mass below, or fibre that has gone wet on the weather side. It is extracted with a vacuum through a drilled pattern, bagged and taken away, then refilled in bead once the wall is dry.
Solid walls, and internal lining. Insulated plasterboard fixed back to the masonry, or a stud and batten frame with mineral wool or PIR board such as Celotex or Kingspan between it. On old brick we favour a breathable build up so the wall can still dry inwards. Where a reveal or a threshold has no room to give, an aerogel backed board gets a useful U value into 20 or 30mm.
External wall insulation. Boards, a render carrier and a thin coat finish outside, which loses no room and cures cold bridging in one go. On a detached house away from the road it is often the strongest option on paper, and the constraint here is design scrutiny rather than the building.
Junctions and vapour. Reveals returned, the floor junction carried down, joist ends thought about, the eaves closed and a vapour control layer taped continuously so the dew point cannot end up in the build up as interstitial condensation. Where an extension meets the original house there is a thermal bridge at the change of construction, and the lining is carried past it rather than stopped at it.
Ventilation. Extract in the kitchen and bathroom, trickle vents in the windows and air bricks kept clear. Approved Document F sets what it has to do once airtightness improves.
How it runs
Surveying and insulating every wall type in Hangersley

Thomas checks how each wall is built, drilling a small test hole where needed, and prices the job himself. The written quote covers the survey and borescope check, the insulation system and its thickness, making good at windows and doors, ventilation, and clearing up, line by line. Any cavity fill should come from a registered installer with a CIGA certificate.
Hangersley's housing runs from Victorian brick on the lanes to one-off sixties detached houses and later timber frame. A cavity wall is checked with a borescope and filled only if clear and dry; a solid wall is lined inside, room by room, with insulated plasterboard; timber frame needs its own approach. Rooms are sheeted and cleaned, and waste leaves with us. If we find a bridged cavity or damp, you are shown a photo and a price first.
Hangersley falls to the New Forest National Park Authority for planning, and Hangersley lies inside the Western Escarpment Conservation Area; the National Park heritage pages explain it, and you can confirm your address on the National Park property map. On National Park land external wall insulation is a planning application rather than a free choice, as the Planning Portal page on external walls sets out. Internal lining needs no permission under the Planning Portal page on insulation. Building control still applies through regulation 23.
Cost
Cavity fill, lining or external: what sets the price
We do not quote wall insulation by the square metre. The flat part of a wall is quick; windows, doors and floor junctions are where the time goes.
The building. A one-off sixties detached house, a Victorian brick house on the lane and an eighties timber frame need three different methods. Cavity fill is injected from outside, from a tower on a bungalow or a scaffold on a taller gable, under the work at height rules. Internal lining is done from inside, one room at a time.
Cavity or solid. An empty, dry cavity is the quickest job. Solid brick has no gap to fill, so the options are insulated lining inside or a render system outside. A borescope through one small hole tells us which you have.
Junctions. Window and door reveals, the floor edge, the eaves and party walls are where cold bridges form and condensation appears. Detailing them properly is most of the labour and the first thing a cheap quote leaves out.
Exposure. An elevation that takes driven rain off open ground is a poor candidate for cavity fill, and lining inside or a different system may be the better answer there.
Ask any quote: was a borescope used, what system and thickness, how are reveals and floor junctions handled, is ventilation dealt with, and who makes good the plaster and decoration?
If damp has appeared
Mould on an outside wall after cavity fill
Fresh damp or mould on an outside wall after insulation usually traces to rain finding a path across the filled cavity, or a cold junction where warm indoor air condenses. Keep the room aired and note where the marks appear.
The form is too slow for this, so call; an unanswered call gets a ring back from us when we are able. We investigate before anything is removed, with a borescope check and a look at the outside of the wall, because the fix depends on the cause. Scheduled work in Hangersley and Ringwood runs Monday to Friday, 8am to 6pm.
Worth knowing
There is no standard house here to quote from
Estate housing is easy to price because one house tells you about forty. Hangersley is the opposite: over four in ten homes are detached and a good many of them were built individually, on their own plot, by whoever the owner used at the time. Two neighbours can have been built thirty years apart to entirely different specifications.
That is a problem for the way cavity insulation is normally sold, because most of the industry prices from a database and a street view photograph. Neither can tell a solid wall from a cavity wall, and neither can spot a timber frame behind a brick skin, which is the one construction where filling the gap does real harm. On this side of Ringwood a house can have three elevations that are fine to fill and a fourth, a later garden room, in timber frame that has to be left alone.
So the survey is longer here than it is on an estate, and the quote is longer too. Every elevation is measured, opened where there is any doubt, and priced separately, with the walls worth doing first listed first. When you compare quotes, the question to ask is simple: how many holes did they drill, and what did they find in each one. If the answer is none, the quote is a guess dressed as a specification.

Questions
Questions about wall insulation in Hangersley
Can a timber frame house have cavity insulation?
No, a timber frame house cannot take cavity insulation. The gap behind the brick skin is a ventilated drainage cavity and it has to stay clear. Filling it traps moisture against the frame, and a borescope identifies it in seconds.
Why survey each wall separately?
Because on a one off house they are often different. An original solid wall, a cavity built extension and a later timber framed addition can all sit on one property and want three different answers.
What should we ask a firm quoting for a fill?
How many holes they drilled and what they saw in each. A quote written without opening the wall is guesswork, however confident the paperwork looks.
Does being inside the National Park change the options?
Only outside: external wall insulation needs an application here and design scrutiny is tight. Anything done to the inside face of the wall is unaffected.
Is external insulation realistic on a detached house?
Technically it is the strongest option, since nothing is lost inside and the cold bridging goes. The limit here is what the National Park will accept on the appearance, so ask before you plan around it.
