Short answer: yes.
The rest of the answer is logistics. A third-floor walk-up in a converted terrace turns a two-hour clean into a four-hour one, and most of that extra time has nothing to do with fibre. It goes on hose runs, water weight, a communal stairwell that belongs to five other households, and a van parked somewhere the council would rather it wasn’t. The carpet is the straightforward part of the day. The stairs decide the rest.
Can a truck-mounted machine reach a third floor at all?
Usually, with caveats nobody mentions on a phone quote.
A standard truck-mount carries 150 to 200 feet of hose on the reel, and you can add another hundred before the pump starts complaining. Three flights of a Bloomsbury conversion is around twelve metres of vertical rise, plus the dogleg at each half-landing, plus the run from the kerb across the front garden and through the communal door. Sixty metres of hose paid out, threaded through two fire doors, looped round a newel post at every turn. The solution pump copes with that easily. What suffers is the recovery side – every extra length of vacuum hose costs you lift, and three floors up you are dragging waste water through a line that fights you for its whole length. Gravity helps once the water is moving. Getting it moving is the work.
What sixty metres of hose does to your water temperature
Solution leaves a well-set-up truck-mount somewhere near 100°C. At the wand, after an uninsulated run up a cold stairwell in February, I have measured 60°C and not been surprised by it. Insulated solution line closes about half that gap and costs a few hundred pounds, which is why most vans on the road don’t have it. It is a boring purchase. Boring purchases get deferred.
That temperature loss matters on a wool twist carrying eight years of pavement grit. Heat does a share of the work that chemistry otherwise has to do, and when the heat arrives at 60°C you compensate with dwell time or with a stronger prespray, and one of those two options is worse for the carpet.
There is a second cost that shows up on the invoice rather than in the pile. Sixty metres of hose takes about fifteen minutes to run out and closer to twenty-five to reel back in wet, and that happens at both ends of the day whether the flat is forty square metres or four hundred. On a small third-floor job the hose handling can occupy a third of the total time on site. The stairs decide the price more than the square metreage does.
How much does the water weigh, and who is carrying it up?
A litre of water weighs a kilogram. That sentence sounds too obvious to write down until you are on the half-landing of a Rugby Street conversion with a full portable and a decision to make.
I did that flat in WC1 a few winters back – third floor, two-bed, engineered oak everywhere except a wool Wilton in the front room that ran about four metres by five, plus the client’s own kelim that she wanted done at the same time and hadn’t mentioned. No lift. The staircase narrowed above the first floor the way they do in those houses, so the machine went up on its side with the tanks empty and the cable coiled on top.
Empty is the only way it goes up. A Prochem portable with a 45-litre solution tank weighs about 35kg dry; fill it downstairs and you are carrying 80kg up three flights, which is how people end up with a machine at the bottom of a stairwell and a claim against the freeholder’s carpet. Fill on site, from the kitchen mixer tap, using a connector that fits. Half the taps in London period conversions take nothing standard, so I carry a jubilee-clip universal, a bath spout adaptor and a length of food-grade hose long enough to reach from the sink to wherever the machine has to sit.
Filling and dumping without wrecking someone’s kitchen
Dumping is worse than filling and nobody plans for it.
Forty-five litres of recovered water has to leave the flat. It goes down the WC pan, through a mesh strainer, in manageable loads – not the bath, because grit scours enamel and the traps in these places are already fighting a losing battle. Grit, hair and grey water do not belong in a bath waste. And never, under any circumstances, into a gully or downpipe in the front garden: those run to surface water drains in most of inner London and putting carpet waste down one is a pollution offence, not a shortcut.
Work out the dump route before the first pass, because the flat you are standing in may not have a WC you can use. Studio conversions on the top floor sometimes have a shower room with a 40mm gully waste and nothing else, and forty-five litres through a shower trap that hasn’t been rodded since the flat was carved out will back up onto the floor you have just cleaned. Ask to see the bathroom. Run the tap and watch how fast it clears.
Here is the position that gets me disagreed with: truck-mounts are oversold for London flats. Above the second floor in a period conversion, a properly specified portable with an external twin vac does better work than sixty metres of hose losing heat and lift on the way up, and the operators who insist otherwise are defending a £25,000 van, not your Wilton. The van earns its money on ground-floor houses and offices with a loading bay. Three flights up a Victorian staircase, it is the wrong tool wearing an expensive badge.
What does the stairwell cost you before you start?
More than the flat does, most days.
The communal parts of a converted house are not the client’s to lend you. The freeholder or managing agent is the responsible person under fire safety law, and a hose running through a propped-open fire door defeats the compartmentation that door exists to provide. I have had a building manager in Marylebone stand and watch a hose for ninety minutes rather than let it sit in a wedged doorway, which was tedious and entirely correct of him.
Two ways round it. Post a second operative on the door so it is attended rather than propped, or route the hose out of a window. The window trick works better than it sounds – sash up on the third-floor front, hose down the outside with a padded sill guard and a rope tie at the sill so the weight isn’t hanging off the wand. Never do it over a public pavement without someone at the bottom. Bay windows make it harder, because the hose wants to hang against the glass of the floor below and the first gust of wind turns it into a pendulum against somebody’s sash.
Fire doors, hold-opens and the thing nobody puts in the quote
Damage to the common parts is the other cost. Hose scores paint off door frames on every pass, so door edge protectors go on before the reel comes off the van. Corner guards at the nosings. Runners over the communal stair carpet, because a wet hose drips its way down three flights and the neighbour on the first floor will find it. A note through the other doors the day before costs nothing and prevents the conversation where somebody’s Ocado delivery can’t get past your equipment.
Where does the van park, and does that change the method?
It changes everything about the method, which is why I ask about parking before I ask about the carpet.
The loading exemption on a single yellow gives you twenty minutes. Twenty minutes covers carrying a portable in. It does not cover a truck-mount engine running for three hours while you clean, and a warden will treat that correctly as parking rather than loading. Bay suspensions in Camden or Westminster want lead time and a fee, and they are worth it on a big job and absurd on a small one.
When the nearest legal space is eighty metres away
Docklands taught me this one. A warehouse conversion off Narrow Street, E14, third floor with no lift, and the closest place the van could legally sit was across a private estate road behind a barrier that the client’s fob didn’t open because she rented and the fob was the landlord’s. Eighty metres of hose would have reached. The barrier meant it couldn’t cross. Portable went in on a sack truck, filled from the kitchen, and the job ran forty minutes long.
How long will a third-floor carpet take to dry?
Better than a basement, worse than you’d hope.
Warm air rises, so the top flat in a converted house is usually the warmest in the building and the carpet benefits. Against that, conversions are terrible for cross-ventilation. Two openable sashes on the same elevation gives you no through-draught at all, and opening them in a damp week pulls moist air in over a wet carpet.
Air movers, old wiring and the 13-amp problem
Air movers fix the airflow and create a different problem. Period conversions often run one ring main for the whole flat, and two air movers plus a dehumidifier on the same circuit will trip the consumer unit – which in a flat like that is sometimes a rewireable board in a cupboard nobody has opened since the eighties. Spread the load across sockets on different sides of the flat. Ask before you plug anything in.
With decent airflow, a wool Wilton three floors up dries in four to six hours. Without it, you are looking at overnight, and the client walking on it in socks at hour three will undo some of the work.
The air movers create a second problem when you come to collect them. They have to come back down the same three flights, usually at the end of a long day, and if you have left them running past six you are either making a second trip across London or leaving equipment with someone you met that morning. I price the return visit in rather than pretend it won’t happen. The stairs decide that too.
That Rugby Street flat: hose off the reel at ten past nine, back on at half two. The Wilton was dry by seven.
