In a Bashley bungalow every room you heat sits under the loft, so bringing that ceiling up to 270mm of mineral wool comes first. Most need a top-up laid across the joists, not a clear-out. Storage boards go up on legs, the eaves keep their ventilation gap, and the tank and pipework are wrapped against the cold. Walls and floors have their own Bashley insulation page.

A tired Bashley loft usually gives itself away like this. The heating runs and the rooms still feel cold. Or somebody has been up for the Christmas boxes and found the wool squashed flat under the boards, with bare joists showing along the edges. Or the loft has gone damp and nobody can say when it started.

We come out and look properly at a Bashley loft before anyone talks about material. What is up there, how deep it really is once you push a rule into it, whether it reaches the wall plate, whether the eaves are still open, and what state the timbers are in. You get photographs and a written itemised quote with the survey, the depth, the ventilation, the boarding and the hatch on separate lines. The site visit and the quote are free.

The work

Rolls, boards and the corners nobody reaches

Getting the depth right matters. Most lofts around Bashley have one layer laid between the joists and nothing over them, which leaves every joist bridging the cold through the ceiling.

The second layer is cross laid at right angles over the top, so the timber is covered and the two layers together come to about 270mm, the depth a renovated loft is expected to reach under Approved Document L. Mineral wool roll does most of it, rockwool or glass wool depending on the product, batts where bracing chops the space up, loose fill where a roll will not go, sheep wool if you would rather have a natural product. Depth is only the means: what it buys is a lower U value across the ceiling, which is the biggest single heat loss in a bungalow, and that is what shows up on the heating bill and the EPC.

Trussed roofs, which is most of them here. A lot of Bashley went up in the 1990s, and a modern trussed roof is a lattice of thin timbers with bracing running through it. You cannot walk about in one, so the material goes in from the hatch outwards and the far corners take the time. The older cut roofs, where you can stand between the rafters, are the easy ones. Either way the access is one hatch, and working out of it is still work at height.

What comes out first. On the edge of the forest, lofts pick things up. Old material that is compressed, settled, patchy or contaminated with droppings is bagged and taken away before anything new goes down, and if birds or squirrels have had a way in we tell you where it is rather than laying wool over the top of it.

The eaves and the air gap. Insulation finishes at the wall plate. Vent trays keep the gap open above it so cross ventilation can carry moist air out under the ridge, and where a roof has no breathable membrane and only old felt underlay, that airflow and the ridge vents are the only things keeping condensation off the underside. Push the wool into the eaves and you have a wet roof by February.

The services. Recessed lights and downlighters get fire rated covers rather than wool over them, cables and wiring are lifted onto the insulation instead of buried in it, and the cold water tank and its pipework get lagged, because once the loft is insulated properly it is a genuinely cold space. In a bungalow that pipework often runs a long way, so it is worth doing all of it.

Chalet bungalows and rooms in the roof. Plenty of houses in Bashley have rooms built into the roof, which means sloping ceilings, dormer cheeks and little triangular voids behind the knee walls. That is rafter level work: rigid board such as PIR or Celotex cut tight between the rafters with a clear air gap above it, a layer under the rafters, and a taped vapour control layer. The voids behind the knee walls get insulated and the small doors into them draught sealed.

Thomas goes up through the hatch to see how deep the old insulation is and what state it is in, and to look at the joists, the eaves, and any pipes or tanks. In a Bashley bungalow the loft covers the whole house; in a nineties detached it is usually trussed, with bracing to work round. His quote covers the survey, bagging and removing old material, the new material to a stated depth, eaves clearance, the hatch, pipework and disposal.

We lay dust sheets from the door to the hatch, bag old wool in the loft and carry it straight out, so nothing is dragged through the house. If damp felt or a cracked cable turns up, the photo and the cost come to you first, and nothing extra happens without your say so.

Laying insulation inside a loft is not development and needs no application, as Planning Portal guidance on insulation sets out. Because the National Park Authority decides planning in Bashley, anything that changes the outside of the roof, such as a rooflight or a run of tile vents, is a different conversation, and the National Park Authority's interactive property map shows what applies, because permitted development is narrower inside the Park. Building control still applies: under regulation 23, renovating more than half of a thermal element brings all of it up to the Part L standard.

We do not price a Bashley loft per square metre. Laying the open floor is quick; the edges are where the hours go. Your hatch and roof. A bungalow with a landing hatch you can put a ladder under, a nineties detached with trusses and bracing everywhere, and a chalet bungalow with rooms already in the roof are three very different jobs. A hatch above the stairs, a crawl space, or boarding to lift and relay all adds time.

Old material. Flattened wool that has to be bagged and carried out, and boxes that need moving, both cost time. Open joists at standard centres are quicker than working round a trussed roof.

Airflow at the edges. Ventilation matters most. Stop the insulation at the wall plate and keep the eaves open, or the warmth you save turns to damp on the felt. Most of the labour is filling the corners, round the hatch, over downlighters, and lagging pipework and tanks left in the cold, to the depth Approved Document L asks for.

Storage. If you keep things up there, lifting the boards on legs lets the insulation sit at full depth underneath.

If the loft is wet

Beads of water on the felt, black mould on the rafters, or insulation that feels damp all point the same way: moist air from the house is reaching a loft with no way to breathe. Shut the bathroom door, run the extractor fan, and hold off adding insulation.

Ring, not the form, because the timbers suffer the longer it goes on. At the first visit we trace the moisture, check the eaves for blockages, and open up enough ventilation to start the drying. Scheduled work is Monday to Friday, 8am to 6pm. A call that rings out gets a call back from Thomas as soon as he is able.

Worth knowing

In a bungalow the loft is also the cupboard

Bungalows are much the commonest house in Bashley, and they share a big ceiling and a shortage of storage. The ceiling area is roughly twice what the same floor area would be in a two storey house, so the loft is where the money is. And there is nowhere else to put anything, so the loft is the store cupboard as well.

Those two pull against each other, and the usual result is boarding screwed flat onto the joists with the insulation crushed underneath it. Compressed wool does very little, so you end up with a loft that looks finished and a house that still feels cold. The fix is a raised floor: loft legs standing off the joists, full depth carried on underneath, and the boards back down on top with the air gap kept clear at the edges.

It is worth deciding at the survey how much of the loft you actually want as storage, because a boarded platform over part of it and full depth everywhere else is cheaper and warmer than boarding the lot. The hatch and the loft ladder get sorted at the same time, since a bungalow hatch opens straight into the room you live in and an unsealed one draughts all day.

Questions

Questions about loft insulation in Bashley

How deep does it need to be?

About 270mm of mineral wool, and in two layers rather than one. The first goes between the joists and the second is cross laid over the top, which is what stops the timber carrying the cold through the ceiling.

Can I still board the loft out afterwards?

Yes, on loft legs. They raise the deck above the insulation so the depth stays and you keep the storage. Boards screwed straight down onto the joists squash the wool and undo most of the work.

How long does a bungalow loft take?

Usually a day: a trussed roof worked from the hatch outwards, old material to clear and bag, or boarding to lift and put back will stretch it. We give you the day at the quote.

Do I need permission in the National Park?

Not for the insulation itself: it is inside the building, so it is not development. Anything that changes what the roof looks like from outside, a rooflight or tile vents, is where the National Park Authority comes into it.

The loft smells and there are droppings up there. What happens?

It comes out before anything goes in. Contaminated material is bagged at the hatch and leaves with us, and we find where they were getting in rather than laying new wool over the problem.
