I’m Paul. I clean windows and gutters in Drumgelloch most weeks, and I’ve been doing this round North Lanarkshire since 2016. Drumgelloch sits on the east side of Airdrie, along the old Glasgow to Edinburgh road, and part of it has been a conservation area since May 1975. That designation decides what your house is made of, what you’re allowed to change, and — more than people expect — how it has to be cleaned.
There are two Drumgellochs, and I work both
The conservation area is the historic core. North Lanarkshire Council’s Drumgelloch conservation area appraisal traces the street grid back to 1795, when the turnpike road through Airdrie and Bathgate opened, laying out Flowerhill Street, Drumbathie Street and Clark Street running west to east, with Biggar Road and Drumgelloch Street crossing north to south. The area takes its name from Drumgelloch House, a single-storey neoclassical villa from around 1810. Springwells Avenue has rows of late 19th century semi-detached masonry villas. The houses fronting Clark Street are white rendered with pitched roof dormers.
Then there is the rest of Drumgelloch — the post-war semis and the 1960s and 70s council-built homes on the streets around that core. That is where most of my work here actually is.
Same round, two completely different jobs. A pure water pole handles both, but what you must not do to the house changes entirely between them.
Sandstone, Scottish slate, and windows you can’t just replace
The council’s appraisal is blunt about what the conservation area is built from: “The dominant materials are sandstone, Scottish slate roofs and timber sash and case windows.”
Each of those three changes the job:
Sandstone takes no pressure. It is porous. Force water into it and you drive damp into the wall and strip the surface. Anyone who turns up at a sandstone villa with a pressure washer is telling you they don’t work on these houses.
Scottish slate is fragile and holds moss. Slate roofs don’t want to be walked on or blasted. The moss sitting on them is the real problem, and it isn’t a roof problem for long — see below.
Timber sash and case windows need to stay dry. Pure water and a pole are fine on them. What destroys them is standing water: a blocked gutter overflowing down the wall onto the sills and the bottom rail, year after year.
Why that matters more here than elsewhere in Airdrie
The conservation area carries an Article 4 Direction. Since the permitted development rules changed in February 2012, most householder work inside the boundary needs planning permission. So if those timber sash windows rot out, swapping them for uPVC is not a weekend decision — it is an application.
The council’s own management plan goes further. Policy DE2 commits it to “encourage good building maintenance and early (preventative) repair by owners… use of legislation where necessary to halt deterioration.”
Put plainly: in Drumgelloch, looking after what you already have is both cheaper and simpler than replacing it — and the council would rather you did. Keeping gutters clear and slate free of moss is the cheap end of that. It is also the bit I do.
The north side fills first
Here is the thing I see on this round that you won’t find in any council document.
The gutters on the north side of the house block first, every time. Two reasons stack up. The eastern part of Drumgelloch is villas in large gardens with mature trees, so there is leaf fall to deal with. But the bigger one is moss: north-facing slate gets no sun, holds damp, and grows a mat of moss that slides off into the gutter. By the time a customer rings me, the gutter is usually more moss than leaf — heavy, wet, packed solid, and nothing like the loose stuff people picture.
That is why I check the north elevation first here, before anything else.
Gutters are cleared by hand so the compacted silt and moss come out, not just the loose leaves on top. Where a roof is too high or the access is too tight for a ladder to be safe, I use vacuum poles from the ground instead. Same price either way.
What it costs around Drumgelloch
Windows are £10 for a small terraced house and £12 for a three-bed semi. Gutters are from £25 per side, so a typical two-sided semi is from £50. Fixed price agreed before I start, and nothing to pay until the work is done.
One person, one visit, one bill. You get me every time, which on a street like this matters — by the second visit I already know which side of your house fills up first.
Questions I get asked on this round
Do I need permission to have my windows cleaned in a conservation area?
No. Cleaning is maintenance, not development. Permission comes into it when you alter or replace something — new windows, new roof covering, a rendered wall. Cleaning is exactly what the council’s management plan encourages.
Can you pressure wash my sandstone frontage?
No, and nobody should. Sandstone is porous and pressure drives water into the wall. If a frontage genuinely needs work, that is a job for a stone specialist, not a cleaner.
My roof is covered in moss. Can you not just leave it?
You can, but the moss doesn’t stay on the roof. It comes down into the gutter, and a gutter packed with wet moss overflows down the wall. On a house with timber sash windows, that overflow is what eventually rots the sills.
How often do gutters need doing here?
Once a year suits most houses in Drumgelloch. Twice if you have mature trees within about ten metres — which, in the eastern part with the big gardens, plenty of people do.
