Dry rot, wet rot and woodworm in Paisley
Paisley holds the largest concentration of pre-1919 property in the West outside Glasgow itself, and with it the two things that make timber decay here complicated: shared ownership, and water that has been in the building before.

Paisley is not a suburb of Glasgow in building terms and treating it like one leads people wrong. It is an old industrial town in its own right, built up around the thread mills and the abbey, with a dense core of Victorian and Edwardian sandstone tenement, a large stock of listed and conservation area property, and a set of mill and warehouse conversions that exist almost nowhere else on our patch in that quantity.
The technical picture is close to Glasgow’s: solid walls, no cavity, floor joists built directly into stone, and rainwater goods shared between everyone in the building. What is genuinely different is the history of water. The White Cart Water runs through the middle of the town, parts of it have flooded within living memory, and a surprising amount of the rot we are called to here has a flood or a long-running escape of water somewhere in its past, sometimes decades back.

Three questions. You do not need to know which problem you have.
What flooding leaves behind, years later
This is the Paisley-specific point worth understanding, because it is counterintuitive and it costs people money.
When a property floods, the response is drying, and drying is measured on the surfaces that can be measured: plaster, screed, the faces of walls. Those genuinely do dry. What does not necessarily dry is everything below and behind them. Water that has run under a suspended timber floor sits in the sub-floor void, in the ash or rubble fill some older buildings have there, and in the base of solid walls where there is no damp proof course to stop it. That space is unheated, unventilated and unseen. Timber in it can stay at a moisture content high enough to decay for years after the rooms above have been redecorated and forgotten about.
That is the classic route to a dry rot outbreak that appears to come from nowhere: a wet, still, enclosed void with timber in it and no air movement. If your building has any history of flooding, an escape of water, or a burst that ran for a while before anybody noticed, that history is the single most useful thing you can tell a surveyor, and it should change where they start.
The three building types, and what each does
Tenement and terrace
The town centre, the streets around the abbey, Castlehead, Charleston, Ferguslie and the older parts of Williamsburgh. Joist ends bedded in solid sandstone with nothing between the timber and the wall, so anything wetting the wall wets the timber inside it. Overwhelmingly the water comes from above and outside: a cracked hopper, a blocked or split downpipe, a wallhead gutter that has not been cleared in years. Thedry rot page for the West sets out what the treatment involves and why the repair has to reach past the visible damage.
Mill and warehouse conversions
Paisley’s thread mills and the smaller industrial buildings around them have been turned into flats over the last three decades. These are structurally unlike anything else in the town: very large original timbers carrying real load, frequently with historic beetle damage in them, wrapped in modern insulated construction. The two questions are always the same. Is the old woodworm damage finished or is something still living in it, and is the new envelope holding moisture against timber that used to be able to dry. Both need somebody physically looking at the timber, and in a conversion the finding usually concerns common structure rather than one flat.
Interwar and post-war housing
Foxbar, Glenburn, Gallowhill, Hunterhill and the outer estates. Cavity walls and suspended timber ground floors on the earlier stock. The problem here is plain wet rot from blocked underfloor ventilation, and the causes are the ordinary ones: a driveway laid up to the wall, a raised border, or an extension built across the airbricks on one elevation. Cheap to prevent, tedious to put right once the joist ends have gone.
The conservation constraint is a timing problem, not a barrier.Large parts of central Paisley are listed or sit inside a conservation area, and repairs that affect the external appearance of those buildings generally need consent before work starts. Since the things that cause rot are usually the external things, the rainwater goods, the stone, the slates and the windows, that consent stage sits directly in the path of the fix. It is manageable if you know about it early. It is a serious delay if you discover it after the survey, and rot does not pause while an application is considered.
Shared repairs when there is no factor
A good number of Paisley tenements are self-factored or not factored at all, which means there is no managing agent to instruct the work and no standing arrangement for splitting the bill. Scottish tenement law still gives you a route through the Tenement Management Scheme, under which the owners can take a majority decision on maintaining common parts, but somebody has to start it and somebody has to convince the others.
What actually moves that along is evidence. A written survey describing what has failed, what is causing it and what happens if it is left is a document the other owners can read and act on. A conversation about a smell in the close is not. This is the practical reason to get a survey before the negotiation rather than after it, quite apart from finding out how far the decay has already reached inside your own flat, where you can act alone and do not need anyone’s agreement.
Booking a survey in Paisley
Paisley is a routine visit for the West of Scotland team rather than an outlying one. Three things are worth putting in the enquiry, because each one changes where a surveyor starts: whether the building has ever flooded or had a significant escape of water, whether it is listed or in a conservation area, and whether there is a factor. If you are not sure which of the three problems you have, that is the normal position and atimber survey covers all of them in one visit.
The rest of the county, including Renfrew, Johnstone, Linwood, Erskine and the villages, is covered on theRenfrewshire page.
Questions we get from Paisley
The close flooded years ago and it was dried out at the time. Could that still be causing rot now?
Yes, and it is one of the more common histories behind a dry rot job in Paisley. Drying out a property after a flood usually means drying the rooms people can see. Water that got under a suspended floor, into a sub-floor void or into the base of a solid wall can stay there long after the plaster is dry, because there is no ventilation and no heat down there to shift it. Timber sitting in that stays damp for years. If your building has flooded at any point, say so at the enquiry, because it tells a surveyor to open the floor rather than trust the walls.
Our building has no factor. How do we get a shared repair agreed?
Slowly, and in writing. Where there is no factor, Scottish tenement law still gives you a route: the Tenement Management Scheme lets the owners take a scheme decision by majority on maintenance of common parts, which includes the roof and the rainwater goods. In practice the thing that unsticks it is evidence. A written survey saying what is wrong, what is causing it and what it will do next is a far better thing to put in front of six sceptical neighbours than a description of a smell in your hall. That is the main reason it is worth getting one before the argument rather than after it.
The building is listed or in a conservation area. Does that stop the repair?
It does not stop it, but it does shape it and it adds time. Repairs affecting the external appearance of a listed building, and many affecting one in a conservation area, need consent from the council before the work goes ahead, and there are usually expectations about matching original materials and details rather than substituting modern equivalents. That matters most for the things that cause rot in the first place: cast iron rainwater goods, stone, slate and timber sash and case windows. Build the consent stage into your timetable from the start, and get the survey done first, because the application is much easier when you can say precisely what is failing and why.
We are in a converted mill. Whose problem is the old timber?
The building’s, which means everybody’s, and the deeds decide the split. In a mill conversion the original structural timber, the beams and the floor structures, is normally common property in the same way a tenement roof is, even where a beam runs through your own flat. What is yours alone is usually the internal finishes. That distinction is worth getting straight early, because a survey finding in a converted mill often concerns structure rather than decoration, and the wrong assumption about who pays wastes weeks.
Is Paisley worse for this than Glasgow?
Not worse, but the mix is different in two ways that matter. Paisley has a very high proportion of pre-1919 property relative to its size, and it takes more driven rain than most of Glasgow because of how exposed Renfrewshire is to weather off the estuary. Set against that, the town has less of the deep, sunless back court arrangement that keeps Glasgow tenement masonry from ever drying. The honest summary is that the buildings are similar, the weather is harder, and the ownership arrangements are frequently more tangled.
