West of Scotland, East Kilbride
Woodworm, wet rot and dry rot in East Kilbride
Almost everything written about timber decay in the west of Scotland is written about tenements. East Kilbride barely has any, and the problems here are a different set entirely.

East Kilbride was designated Scotland’s first new town in 1947, and the consequence for anybody dealing with rot or woodworm here is simple: the building stock starts where Glasgow’s ends. Outside the old village core, almost nothing here is pre-war and a great deal of it was put up between the nineteen fifties and the nineteen eighties. There are no wallhead gutters, very few solid sandstone walls, hardly any joists built into stone, and almost none of the shared close arrangements that dominate a city job.
That is why generic advice tends to miss here. What East Kilbride has instead is a very large quantity of post-war construction that has now passed sixty or seventy years old all at once: original flat and shallow pitched roofs, timber cladding panels, timber frame behind the outer leaf, and roof timber from an era before pre-treatment was standard. Those are the things we get called to, and they fail differently from a tenement.

Three questions. You do not need to know which problem you have.
Why woodworm comes up here more than anywhere else on our patch
Of all the town names people search alongside woodworm in the West, East Kilbride is consistently near the top, and the building history explains it rather than any local peculiarity of the beetle.
The common furniture beetle lays into the sapwood of untreated softwood. Pre-treated structural timber did not become the norm in British house building until the nineteen seventies, so a very large share of the roof trusses, floor joists and boarding installed across the new town in its first two decades went in untreated. Add lofts that were poorly ventilated by modern standards and, in many houses, later insulated in a way that made them colder and damper still, and you have conditions the beetle is content with.
None of which means treatment. It means the question is worth asking properly. Most of what we are shown in East Kilbride is old, finished damage from an infestation that died out decades ago, and treating that changes nothing about the timber. Fresh, clean, pale holes with soft dust below them are a different matter. You can make a start on the distinction yourself:how to tell if woodworm is active covers what to look for with a torch tonight, and thewoodworm page for the Westexplains what treatment actually involves if it turns out to be needed.
The three failures we are called to most
Flat and shallow pitched roofs
A defining feature of the early new town housing and the single most productive source of wet rot in it. A flat roof relies entirely on its covering, and every original covering here has been renewed at least once by now, sometimes badly. Water gets in at an upstand, a parapet, an outlet or a joint, soaks the timber deck, and is then held there because there is nowhere for it to drain and very little ventilation above the ceiling. The ceiling below often stays unmarked for a long time, which is why the extent is regularly a surprise when the deck is finally opened up.
Timber cladding panels and the junctions around them
Panels of timber cladding, often below or between windows, are everywhere in the town’s original housing. They are exposed on all sides, they rely on a paint or stain film that needs maintaining, and the timber behind the visible face is frequently in worse condition than the face suggests. Water that gets past a failed joint runs down inside the panel and collects at the bottom rail, which is exactly where we find soft timber. Replacement windows fitted into these panels without the surround being properly made good are a common way in.
Timber frame, where the structure is out of sight
From the late nineteen sixties onward a large amount of housing in the town is timber frame with a masonry or clad outer leaf. This is sound construction and it is not a defect. What it changes is diagnosis. The structural timber sits inside the wall behind a membrane, so it is not visible, and anything that bridges the cavity, mortar droppings, a badly fitted vent, a wrongly detailed extension, can carry water from the outer leaf onto the frame where nobody will see it. That is a survey question, not a look-and-see question.
Dry rot is the rarest of the three here, and that is genuinely good news. Dry rot needs sustained moisture in poorly ventilated enclosed spaces, and it spreads through and across masonry, which is why it thrives in solid-walled tenements with shared, neglected rainwater goods. East Kilbride’s cavity walls, individual roofs and separate drainage give it far less to work with. When we do find it, it is usually in the old village or in a property where a long-running leak has been left alone in an enclosed floor or roof void.
What is different about the older parts of town
East Kilbride village predates the new town by centuries, and the property around it behaves like older property anywhere: solid walls, traditional construction, and the decay patterns described on theLanarkshire page rather than the ones on this one. The same goes for the handful of older farms and lodges absorbed into the town as it expanded. If your house is one of those, you are dealing with a nineteenth century building that happens to have a new town address.
Booking a survey here
East Kilbride is inside the core patch for the West of Scotland team, so it is a routine visit rather than a special trip, and that covers The Village, Calderwood, Murray, Westwood, St Leonards, Greenhills, Whitehills, Stewartfield, Mossneuk and Lindsayfield alike.
Two things are worth telling us at the enquiry, because they change what the surveyor needs to bring. First, whether the roof is flat, shallow pitched or conventional. Second, whether you know or suspect the house is timber frame. If you do not know, say that rather than guessing, and if you are unsure which problem you are even looking at, book atimber survey that covers all three in one visit.
Questions we get from East Kilbride
The house is from the sixties. Is it not too new to have woodworm?
No, and East Kilbride is the clearest example of why. The common furniture beetle goes for the sapwood of untreated softwood, and a great deal of the roof and floor timber installed in Britain between the nineteen fifties and the mid nineteen seventies was exactly that. Pre-treated structural timber only became normal later. So a nineteen sixties loft is not too new, it is close to ideal. What we usually find is old damage that stopped years ago rather than a live infestation, but the way to know is to look at whether the holes are fresh, not at the date the house was built.
Our roof is flat. Does that make rot more likely?
It makes wet rot more likely if the covering has reached the end of its life, which on a good deal of the original new town stock it has, more than once. A flat or very shallow roof holds water rather than shedding it, so a small failure at an upstand, a joint or an outlet has a much longer time to get in. The timber deck underneath is then wet and unventilated, which is the combination that produces rot fastest. The important point is that the ceiling below usually looks fine long after the deck above it has started to go.
Is my house timber frame, and does it matter?
A lot of East Kilbride housing built from the late nineteen sixties onward is timber frame, and it matters mainly for how a survey is done. In a timber frame house the structure is inside the wall behind a breathable membrane, with a masonry or clad outer leaf and a cavity between. That is a perfectly sound way to build, but it means the structural timber is not visible and a leak that bridges the cavity puts water onto framing nobody can see. If you are not sure which you have, say so at the enquiry: it changes what the surveyor brings and where they look.
There are no tenements here. Does the shared repair problem still apply?
For most houses, no, and that is a genuine advantage of living here. If you own a semi or a terrace in Westwood or Greenhills, the roof and the gutters are yours and you can commission work without a committee. The exception is the flatted blocks, which East Kilbride has plenty of. Four-in-a-block and low-rise flats share a roof and rainwater goods between owners under the same Scottish tenement rules that govern a city tenement, and where South Lanarkshire Council or a housing association still owns some of the flats, they are one of the parties whose agreement is needed.
The survey found rot at the bottom of a wall, but the wall is concrete. How?
The wall being concrete does not mean there is no timber in it or against it. In post-war construction you commonly find timber sole plates, battens, strapping and linings fixed to or built into concrete and blockwork, along with door and window subframes. Concrete also conducts moisture readily, so a wall taking water at the base transfers it straight into whatever timber is fixed to it. That is why the finding sounds contradictory and is not: the concrete is fine, the timber against it is not.
