Insulation in Stourpaine
Loft top-ups, better access into the roof space, and breathable linings on walls that have to keep drying out.

Yes, you can insulate a house in the conservation area, and in Stourpaine a loft or an inside wall on an unlisted house needs nobody's permission. What needs care is the small number of jobs that change something you can see from the lane. We come out for free, tell you which side of that line your job falls, and put the whole thing in writing.
Heat loss in Stourpaine usually starts in the same few places. An old cottage that swallows heat and still has cold rooms. A roof space nobody has been into for years, with a thin, dusty layer that has settled between the joists. Or mould coming back in a corner every winter, faster than it can be washed off.
More material on its own does not answer any of those, and on an old building it can make things worse. So the visit is a look at how the house works: what depth is really up there, whether the eaves are open, what the walls are actually built of, how you get into the roof space at all, and where the tank and pipe runs sit. Then a written itemised quote, with the ventilation work and the access work priced as their own lines rather than folded into a single number.
The work
Half the job is getting into the roof space
Getting into the roof space at all. On the older houses in Stourpaine the way in is often a small hatch over the stairs with no ladder and nothing to stand on, and that is a real part of the job, not an afterthought.
We will form a proper opening, fit a ladder and put a boarded walkway in where it makes the loft usable, and it goes on the quote as its own line so you can decide whether you want it. A loft you can get into is a loft that gets looked after.
A layer that went down in a Stourpaine loft decades ago will have compressed under foot traffic, settled into the gaps and often drifted away from the perimeter altogether. Dry, intact mineral wool stays and takes a fresh eco roll over the top at right angles, between and over the joists, so no timber is left carrying cold through the ceiling, and the pipe runs above it get lagged. Anything wet, crushed or full of nesting comes out, gets bagged on the spot and leaves with us rather than sitting in your garden. A renovated ceiling is expected to reach a U-value of 0.16, nearer 270mm of quilt than the 250 people remember.
Solid cob, brick and flint walls have no cavity to fill and survive by drying out through their faces, so an internal lining has to be vapour open: a wood fibre or mineral board with a lime finish, with the cold bridge at the joist ends and the reveals properly detailed. Inside the Stourpaine Conservation Area, external wall insulation is a planning conversation before it is a technical one. The later houses behind the street do have cavity walls, and those get a borescope before anybody talks about filling them. Kitchens added on behind a cottage usually sit under a shallow lean-to with a few inches of space and nothing in it, and they are the coldest rooms in the house. Where the covering is coming off one of those the answer is a warm roof, rigid PIR board over the deck, or a multi-layer quilt such as TLX under a sloping ceiling with no depth to give.
How it runs
Insulating an older house without trapping damp
Thomas comes out and prices it himself. He goes into the loft to see what is there and how it is ventilated, looks at whether the walls are solid or cavity, and checks for damp before recommending anything. The written quote is itemised: survey, clearing old material, the insulation and its thickness, any vapour control or breathable membrane, keeping ventilation paths clear, and disposal. The job then follows that list.
Lofts are boarded across so nobody puts a foot through a ceiling, and the landing and stairs are sheeted. Old insulation is bagged in the loft and carried straight out. Damp timber, a leak or old cable found under the old layer is photographed, priced and left for you to decide on.
Insulation inside the house is an improvement rather than development, so it falls within permitted development, and the Planning Portal explains where that ends. Building control gets involved once a thermal element is renovated or the roof space is turned into a room, and the Building Regulations then set the level the work must reach. On a listed building listed building consent covers inside work too. If a conservation area covers your address, anything on the outside face goes to Dorset Council first.
Cost
Hatch, timbers and old material: the insulation cost
No rate per square metre, because a loft and a wall of the same size can be very different jobs.
How you get in. A cottage with a small trap above the stairs, an older cut roof full of purlins and struts, and a later house with a wide trussed loft take very different amounts of time. A thatched roof is another matter again, since the thatch has to keep air moving underneath it.
What has to come out. Old, flattened or damp insulation is bagged and carried down before anything new goes in. Stored boxes and loose boards have to be moved. If the hatch is too small to get a roll through, enlarging it is a cost of its own.
The walls. An old solid wall of flint, brick or cob cannot be cavity filled. It can be lined on the inside, which means skirtings off and making good afterwards, or it is better left alone until a damp problem is sorted.
What it must reach. Approved Document L sets the target, and on an older house the ventilation has to be planned alongside it.
When you compare, ask each firm how thick the insulation will be, whether the old layer is removed, and how the roof space will stay ventilated.
If it is urgent
Condensation, mould or a room that will not warm up
Phone about this, and skip the form. Water dripping in the loft, mould coming back on a bedroom wall or a room that never warms up all point to air, heat and moisture going the wrong way.
Until we get there, open the trickle vents, keep furniture a hand's width off cold outside walls, and dry clothes somewhere other than a closed bedroom. The first visit finds the cause before anything is added, because insulation in the wrong place can make damp worse. Scheduled work runs Monday to Friday, 8am to 6pm. If the call rings out, expect us to ring back as soon as we can.
Worth knowing
The conservation area, and the vents nobody warns you about
The conservation area controls how the village looks, not how warm your house is. A loft top-up, a breathable lining on the inside of a wall, a floor, a draughtproofed hatch: none of those change anything visible from the lane and none of them need permission. The two obvious exceptions are the ones everybody expects.
External wall insulation thickens the walls and changes every reveal and eaves line on the elevation, and a rooflight or a dormer on a conversion puts something new on a roof slope people can see. Both are planning conversations before they are technical ones.
The one that catches people out is ventilation. Once you make a roof space properly cold you have to let it breathe, and Approved Document F sets out what it needs.
In a sheltered old roof the answer is often to ventilate at the eaves, which is invisible, but where the eaves are boxed in or the roof is shallow the honest answer can be tile vents or a ridge vent, and on a designated street the type and position of those is a visible change. We look at that before the quote rather than turning up with a box of vents on the day. If the answer is that something has to show, you hear it at the visit, with the alternative and what it costs, so you can ask the council rather than find out afterwards.

Questions
Questions about insulation in Stourpaine
We are in the Stourpaine Conservation Area. What needs consent?
Anything that changes what the street sees. Adding a rooflight to a visible slope, cutting vents through the covering or changing the covering itself is a design matter for Dorset Council. Rolling quilt over the joists is not, because nobody outside can tell it has happened. The line drawn here is that like for like maintenance goes ahead and a change of material or appearance is a conversation first.
We are off the mains and on oil. What order do things go in?
Roof, then draughts, then heating. Plenty of households in Stourpaine run on oil or electricity, so heat is bought in advance and stored, not drawn off a main as you use it. That makes waste more obvious than it is in a gas house. Fixing the ceiling first means the fuel already sitting in the tank lasts further into the winter.
The west wall gets battered. Does that decide the specification?
It decides where the care goes. The most exposed face in Stourpaine looks west, and driven rain on that wall keeps the masonry damp, which makes it conduct more heat than the dry sides do. Wind pressure on the same face pushes air through gaps at the eaves and around the frames. So the west elevation gets the sealing work and the sheltered sides are left unless there is a reason.
The ground is chalk here. Is a cold floor normal?
Free draining ground is not what makes a floor cold. A solid slab laid straight on the earth with nothing beneath it is, and so is a suspended timber floor over a ventilated void, which is what the older Stourpaine houses tend to have. Air moving under the boards pulls heat out of them. Insulating between those joists from below, with the air bricks left clear, is the answer.
Who turns up to price it?
Thomas Hannen, who owns the firm. He does the visit, gets into the loft and writes the quote himself, so there is no gap between the person who looked at it and the person who set the figure. Bournemouth Roofing and Building Ltd is registered in England and Wales, company number 15471719. The visit and the written itemised quote are free, and Stourpaine is well inside the patch we work.
