After builders cleaning in London, Liverpool & Manchester

After-builders cleaning starts at £243 for a flat or studio and £425 for a three-bed house, or £30 an hour if you would rather pay for time. We use HEPA vacuums for the fine dust that gets everywhere, the right removers for paint, plaster, silicone and grout haze, and pH-neutral products that will not mark new finishes. We cover London, Liverpool and Manchester. That is the short answer; the detail is below.

After builders cleaning is the deep clean a property needs once it comes out of renovation, an extension, or new-build work. We deal with what an ordinary clean leaves behind: fine construction dust, plaster haze, paint speckle, grout residue, silicone smears, sticker glue, and the grey film that coats every surface the moment the trades pack up. Monster Cleaning has handled this work across London, Liverpool and Manchester since 2014. The rate is £30 an hour per cleaner, kit and products included, nothing bolted on at the end. Call 0333 555 2076 for a price. It takes about three minutes on the phone. The rest of this page is the detail.

Why your regular cleaner cannot do this job

Builders build. Cleaning afterwards almost never sits inside that contract, whatever the quote sometimes implies. The “broom-swept” finish most jobs end on is exactly that literal: someone ran a brush over the floor, and everything else stays where it landed.

Construction dust does not behave like household dust. Plaster and MDF particulate is fine, somewhere between 1 and 10 microns, light enough to hang in the air for hours after any movement in the room. You hoover, you go to put the kettle on, you come back, and there is a fresh layer on the windowsill. It settles in the places nobody checks: inside cupboards that were shut the entire build, on the top edge of doors, in the groove behind the radiator, on the back of every cupboard hinge, between the fins of the extractor. A domestic hoover tends to blow most of it straight back out through the filter, finer this time. We worked that out the slow way on a Fitzrovia flat in 2018 and had to go back the following week to redo three rooms on our own time. Lesson learnt. HEPA H13 on every after-builders job since.

Then there is the residue. Paint flecks welded onto new aluminium frames, which become a real problem once they have had a fortnight to dry. Silicone smears on the tile, where a finger ran along the sealant and then brushed the grout. Grout haze, which looks like a faint white film until light catches it at the wrong angle. Sticker glue on the appliances. Protective film left on a radiator for six weeks in July that has gone tacky. None of this comes off with a supermarket kitchen spray, and half of it will scratch if you go at it with the wrong cloth. Matt emulsion is the least forgiving of the lot. One pass with an abrasive side-scrubber and you have burnished a shiny patch that shows under every downlight until the next repaint. Knowing which solvent lifts which residue from which surface is most of what we get paid for.

What is included

Every after-builders booking covers the whole property. Nothing gets priced as an extra once we are on site.

Throughout the property

• Dust extraction from all surfaces, top down: ceilings where we can reach from a step ladder, walls, cornicing, picture rails, shelves, skirting, architraves, door frames, window sills, radiators (including behind), and light fittings.
• HEPA-filter vacuuming of every floor, including the grout lines on tile.
• Mopping of hard floors with a pH-neutral solution, which matters on new stone, engineered wood and LVT, all of which alkaline products can damage.
• Wipe-down of every socket, switch, thermostat, door handle and finger plate.
• Paint and plaster spot removal from hard surfaces, the chemistry matched to the finish.
• Internal glass, shower screens, splashbacks, mirrored wardrobes.
• Removal of manufacturer labels, protective film and sticker residue from new fixtures, sanitaryware, appliances and radiators.
• Dust pulled out of air vents, extractor grilles, and the trickle vents on double glazing, the bit most people forget.

Kitchen

• Inside and outside of every cupboard, including the drawer runners, where MDF dust hides most.
• Full wipe of appliance fronts, tops and visible sides.
• Sink, taps and splashback descaled and polished up.
• Hob, extractor hood and filter housing degreased.
• Silicone seal along worktops and splashback checked and wiped.

Bathrooms and wet rooms

• Toilet, bath, shower tray and basin deep-cleaned and disinfected.
• Grout haze and cement residue removed from new tiling (acid-based product, applied carefully, rinsed thoroughly).
• Taps, shower heads and wastes descaled.
• Mirrors, glass screens and chrome polished.
• Leftover fitter’s silicone smears chased off every joint.

Why we are a sound pick for this particular job

We are an accredited member of the British Institute of Cleaning Science and fully insured for post-construction and new-build work (£5m public liability, £10m employer’s liability, cover docs on request, and we forward them straight to your developer or managing agent if they ask). Every cleaner on an after-builders job has done this specific work for at least 18 months. It is not where we put new starters. Too easy to scratch a £2,000 quartz worktop with the wrong pad. Too easy to miss the one spot the snagging surveyor will go straight to. Above a one-bed we send two cleaners as standard: a second pair of eyes, and the job finishes the same day.

What it costs

The hourly rate is £30 per cleaner. The final figure comes down to two things: the size of the property, and how much the builders left behind. A tidy contractor doing a single-room refurb can land you under the estimate. A full gut job, where the crew vanished the second the skip was lifted, usually sits at the top of the bracket, sometimes past it. We say honestly on the phone which end of the range you are at, and if we walk in and find it considerably worse than described, we stop and have the conversation with you before pressing on. No mystery invoices. Every figure above includes products, kit, and travel within our standard coverage area. The complete pricing across all our services is on the prices page.

After builders, deep clean or regular clean

A fair number of people ring unsure which of the three they actually need. The quick comparison:

The multi-stage method, and why ventilation matters

After-builders work is not one pass. Do it in a single sweep and the fine dust you disturb in stage one settles back onto everything you cleaned in stage two. We work it in stages, in order, because that order is what makes it stick.

1. Open it up. Windows and trickle vents open, doors wedged, cross-ventilation going before a cloth touches anything. A renovated room holds a lot of suspended silica and plaster particulate, and moving air carries the worst of it out rather than letting it resettle. It also clears any solvent vapour as we go.
2. Top-down dust extraction. HEPA H13 vacuums first, ceilings and high ledges down to skirting, so gravity works with us. Brushing before vacuuming just launches the dust back into the air.
3. Residue and sticker removal. Paint speckle, plaster spots, grout haze, silicone smears and sticker glue lifted with the solvent matched to each surface, patch-tested first on anything delicate.
4. Wet stage. pH-neutral floors, glass, sanitaryware, the final wipe-down of every surface once the airborne dust has dropped and been pulled out.
5. Final pass. A walk back through with fresh eyes, because the light at 4pm shows up a grout-haze shadow the morning light hid.

How booking works

1. Ring 0333 555 2076. Tell us the size of the place, what work was done, and when you need it sorted. Price on the phone, usually under three minutes.
2. The slot goes in the diary. Seven days a week, 7am starts if you need an early finish. Book 5 to 7 days ahead for the best chance of your preferred date. Even so, last-minute slots come up more often than you would think, especially midweek, so it is worth asking even if the builders have only just rolled up the dust sheets.
3. The van arrives with everything. HEPA extractors, pH-neutral floor solution, specialist residue removers, solvents, microfibres, ladders, bin bags. Nothing required from you.
4. We finish the job, not the clock. If it is going to overrun the estimate, we pause and speak to you about it first. Nobody walks off a half-done property.

Services that often go with this one

An after-builders clean takes the property out of its building-site state. To get it all the way to move-in-ready, these tend to get added to the same visit:

• Carpet cleaning. Plaster dust sinks deep into pile. Even a HEPA hoover only takes the top 2 to 3mm. Hot-water extraction at 90 to 95C lifts the rest out.
• Window cleaning inside and out. New builds especially come with paint flecks on the frames and cement run-off on the glass.
• Oven cleaning. If the oven was in the property during the works, there is a grey film inside the door seal and on top of the fan. We strip it down and do it properly.
• Pressure washing. Driveways, patios and paths: paint drips, mortar splashes and cement run-off always happen, and they are much easier to deal with in the first month than six months later when the rain has driven them in.

Frequently asked questions

How long does after builders cleaning take?
Usually 4 to 12 hours, depending on size and how much the trades left behind. A one-bed flat after a tidy kitchen refurb often comes in at 4 to 5 hours with one cleaner. A four-bed house after a full renovation is a day with two cleaners, sometimes longer. We work the estimate out when you ring, and the quote is based on that estimate.

How soon after the builders leave should I book?
As soon as they have cleared their tools, materials and waste. Do not leave it weeks. Fresh plaster dust comes off surfaces fairly easily. Dust that has had a month to settle, draw in a bit of humidity and re-dry is much harder to shift, and you can end up paying for a deep clean on top of the after-builders one.

Is an after builders clean the same thing as a deep clean?
No. A deep clean goes after the grime, grease and neglect of everyday living. An after-builders clean deals with construction residue: fine dust, plaster, paint, grout haze, sealant smears, sticker glue. Different products, different kit, different technique. If the property was lived in before the renovation started, you may want both, and we often run them on the same day.

Do you remove builders’ waste and rubble?
No. We take away small amounts of leftover bits as part of the clean, like offcuts, packaging and dust sheets. Skips, bulk rubble and construction materials need a specialist waste removal firm before we turn up. If the site still has plasterboard offcuts piled in the hallway when we arrive, we cannot clean around them.

Can you clean a new-build before I move in?
Yes, and it is one of our most common bookings. New-builds carry nearly as much dust and protective film as a refurb, plus factory sealants, build dust inside every cupboard, and usually a layer of grime in the boiler cupboard nobody thinks to check. We clean a new-build to full move-in standard, inside all white goods, wardrobes and fitted units.

Is your team insured?
Yes. £5m public liability, £10m employer’s liability. Cover docs on request, and we send them straight to a developer, contractor or managing agent ahead of the job if you need that.

Will your cleaners damage the new paint, worktops or floors?
In twelve years of doing this we have not had to replace a damaged surface on an after-builders job. Every cleaner on this type of work has a minimum 18 months on the specific job type. We use non-abrasive cloths and pH-neutral solutions on anything we have not confirmed the material of, and solvents get tested on a hidden patch first, before they go anywhere near matt paint, engineered timber or natural stone.

Do I have to be there during the clean?
No. Most customers leave keys with us, with a concierge, or in a key safe. We lock up when we go and send photos of the finished rooms. If you want to be there for the walk-through at the end, we message you about 30 minutes before we wrap up.

Is it worth doing the clean before the snagging inspection?
Yes, and we would push for it. A proper after-builders clean makes defects visible. Scratches, caulk gaps, uneven grout, paint misses, all of them hide under a layer of dust. Clean first, snag second. The list you end up with is far more useful, and you have a stronger position with the developer.

What areas do you cover?
All London boroughs (Zones 1 to 6, plus most of the M25 catchment), Greater Liverpool and Greater Manchester. Ring 0333 555 2076 with your postcode and we will confirm. If you are just outside the standard area, ask anyway. We will often stretch for after-builders bookings because the jobs tend to be bigger and worth the trip.
