The service, locally

After builders cleaning across Merton South London

With 39.6% of the borough's homes being flats (ONS Census 2021), Merton builders cleans split between contained refit jobs and whole-house refurbishments where dust has travelled everywhere. Edwardian villas in Wimbledon, 1930s semis in Raynes Park and Morden, and estates around Mitcham.

Access and parking: Championship-fortnight restrictions in SW19, hill access to Wimbledon Village, and driveways common further out. London Borough of Merton permits, suspensions and dispensations are arranged and paid for by us, and we work around any live skip or hoarding licence on the street.

Typical works here: rear extensions, side returns and loft conversions. Access and parking: Championship-fortnight restrictions in SW19, hill access to Wimbledon Village, and driveways common further out.

Add-ons (optional)

£335–£385

6–8 hrs on site · 2 cleaners

  • Some protection, some not. Plaster and MDF dust on every horizontal surface, paint specks on glass and ironmongery, grout haze on new tiles, silicone smears and sanding dust in the carpet pile. Two passes minimum, because dust falls again.
  • ULEZ applies here and is inside the band above. Merton is outside the Congestion Charge zone.
  • London Borough of Merton permits and bay suspensions are arranged and paid for by us, not added to your invoice.
  • Includes the 72-hour re-sparkle promise: if dust settles again before handover, tell us within 72 hours and we come back to it free.

How the project runs

A builders clean in Merton from programme to sign-off

Five steps, planned around your trades and your handover date — the same sequence on every Merton post-construction clean we run.
  1. Tell us the works, not just the bedroomsA single kitchen refit, a rear extension, a loft, a whole-house refurb or a new-build handover are different jobs. Say what was done and whether the site was sheeted — that decides the stages and the hours, not the floor area.
  2. Get a fixed price and a slot in your programmeThe estimate is fixed against the works, the dust level and any add-ons. Parking, permits, ULEZ, HEPA machines, filters and products are already inside it, and we book around your trades rather than across them.
  3. Stage 1 while the last trades finish, if you need itContractors usually book a rough clean so the site stays workable: debris and sheeting out, floors HEPA-vacuumed, labels off, everything safe for second fix and snagging.
  4. Stage 2 — the full post-construction clean, top downOnce the site is clear, a DBS-checked team works ceiling to floor with HEPA extraction: high dusting, ledges, joinery, glass, sanitaryware, appliances, then floors last — twice over, because fine dust falls again.
  5. Stage 3 sparkle, walk-round and the re-sparkle promiseWe come back for a sparkle pass on handover, photography or move-in day and walk the property with you against a snag sheet. If dust settles again within 72 hours, we return and put it right free.

Why Hello Services

What a builders clean in Merton actually gets you

72-hour re-sparkle promise

Fine dust falls twice, and we say so up front. Walk the property with us at the end, and if anything has settled again within 72 hours, send a photo and we come back to it free.

M-class HEPA extraction, not a domestic vacuum

Plaster and MDF dust is fine enough to pass straight through a household filter and back into the room. Our machines are M-class rated with sealed fine-dust filters, changed between properties.

Finish-safe products and a test patch first

New oak, resin, terrazzo, powder-coated aluminium and freshly painted plaster all fail differently. Nothing stronger than water goes on a new finish without a test patch and the manufacturer's care sheet.

Priced by the works, not by the hour

An hourly rate punishes you for an unprotected site. We quote against what was built and how much dust there is, so a slow job is our problem and the price on screen is the price on the day.

Registered waste carrier for packaging and offcuts

Sheeting, packaging, offcuts and light debris can leave with us under our upper-tier waste carrier registration, with a transfer note issued. Rubble and hazardous material stay with your contractor's licensed route.

Whole-house dust, not just the new room in Colliers Wood

High Street red route, riverside estate roads and new blocks with booked lifts. An extension or loft in Colliers Wood sends dust through the original house, so the quote covers the old rooms, the staircase and the radiators as well as the new space — and the patio route the materials came through.

The three stages

Rough clean, main clean then the sparkle

The same three-stage sequence runs in every Merton postcode, with timings taken from real projects in this borough's housing stock.

3 stages · 26 checked items · every one of them in Merton

Stage 1 — builders' rough clean

2–5 hrs

As the trades finish, before second fix

Get the volume of debris and heavy dust out so the remaining trades are not walking it back through the property. Booked by contractors far more often than by homeowners.

  • Loose debris, offcuts and packaging bagged and removed
  • Protective sheeting and tape lifted and taken away
  • Floors swept and HEPA-vacuumed of bulk plaster and MDF dust
  • Plaster splash knocked off floors, cills and ironmongery
  • Adhesive labels stripped from glazing, sanitaryware and appliances
  • Wet trades' residue cleared from sinks, traps and gullies
  • Site made safe and walkable for the next trade

Stage 2 — the main after builders clean

4 hrs – 2 days

Once all trades are off site

The real work: every horizontal and vertical surface in the property taken top down with HEPA extraction, twice, because fine dust falls again the moment you disturb it.

  • Ceilings, coving, cornices and light fittings high-dusted
  • Walls wiped or dry-sponged where the finish allows
  • Every ledge: door tops, architraves, skirtings, boxing-in, cable ledges
  • Radiators front, back and between the fins
  • Sockets, switch plates, thermostats and smoke detectors
  • Grout haze, silicone smears and paint specks blade-lifted
  • New joinery inside and out — cupboards, wardrobes, drawer runners
  • New sanitaryware, taps, screens and shower trays
  • New appliances de-filmed inside and out, seals and filters
  • Window frames, cills, reveals, tracks, trickle vents and drainage channels
  • All glass and mirrors cleaned streak-free
  • Floors last: correct product for the finish, edges and corners by hand

Stage 3 — the sparkle before handover

2–4 hrs

Handover, photography or move-in day

Dust settles twice. The sparkle catches the second fall plus anything the snagging trades brought back, and it is what the client, the photographer or the buyer actually sees.

  • Second HEPA pass on every horizontal surface
  • Fingerprints off glass, ironmongery, switch plates and appliances
  • Chrome, brassware and mirrors polished
  • Any snagging-trade dust and boot marks cleared
  • Floors re-mopped or buffed to the finish
  • Walk-round with you or your project manager, snag list signed off
  • Photographs of each room for the client file on request

Not included

  • Rubble, plasterboard, tiles and heavy construction waste — that goes with your contractor's licensed disposal
  • Asbestos-suspect material of any kind; work stops and you are told immediately
  • Skip hire, hoarding licences and highway permits for the works themselves
  • Making good: filling, sanding, touching in paint or re-siliconing
  • Removing paint or adhesive where the manufacturer says the finish cannot take it
  • Scaffold-height external glazing without the correct access equipment
  • Garden clearance, spoil removal and landscaping waste
  • Commissioning, testing or cleaning inside live electrical or gas equipment
  • Anything that risks damaging a brand-new finish — we flag it in writing rather than gamble

Add-ons and local costs

What can change the price in Merton and what never does

Add-ons are optional and priced up front across Merton. Everything on the right is already inside your quote rather than hidden in small print.
After builders cleaning add-ons in Merton
Add-onFromTimeDetail
Builders' waste and packaging removal£9045–90 minOffcuts, packaging, protective sheeting and empty tins taken away under our upper-tier waste carrier registration, with a waste transfer note issued. Rubble, plasterboard and hazardous materials are quoted separately.
Post-construction carpet extraction£5540–60 min / roomDry HEPA passes first to lift sanding and plaster dust out of the backing, then hot-water extraction. Skipping the dry stage just turns dust into a paste — so we never do it the other way round.
External window and frame clean£751–2 hrsReach-and-wash on new glazing, frames, cills and reveals to third floor, including mortar splash and render spray. Above that needs access equipment and a separate quote.
Cement and grout haze removal£6060–90 minpH-appropriate haze remover with dwell time on new porcelain, natural stone and terrazzo, then a neutralising rinse so the sealer is not compromised.
Paint, plaster and adhesive removal from floors£6560–90 minBlade and solvent work matched to the floor finish — engineered oak, LVT, resin, tile or stone — with a test patch first. Included on small areas; priced when it is the main job.
MVHR and extract filter change£4530–45 minGrilles, ducts at the terminal and the unit filters. Construction dust destroys MVHR filters, and leaving them in circulates it around a finished flat for months.
Second sparkle visit before handover£1202–4 hrsBooked for the morning of the photography, viewing or client handover, after snagging trades have been back. Dust settles twice; this is the visit that makes the photographs work.
Patio, path and driveway wash-down£951–2 hrsJet wash of mortar splash, plaster runoff and tyre marks on new or existing hard landscaping, plus a drain and gully clear.
New appliance protective strip and first cleanIncludedincludedFilm, foam, stickers and shipping bolts off, oven interior and racks wiped of manufacturing residue, fridge and dishwasher interiors and seals — inside the price on every after builders clean.
Parking, permits and skip bays
High Street red route, riverside estate roads and new blocks with booked lifts. Any permit, bay suspension or dispensation in London Borough of Merton's zone is arranged and paid for by us. If a skip or hoarding licence is still live on the street we work around it rather than asking you to move it.
Waste — what we can and cannot take
Packaging, sheeting, offcuts and light debris go with us under our waste carrier registration and you get a transfer note. Rubble, plasterboard, asbestos-suspect material and anything hazardous stays with your contractor's licensed disposal route.
Congestion Charge
Merton sits outside the Congestion Charge zone, so there is no charge to pass on.
ULEZ and LEZ
Every Hello Services vehicle is ULEZ- and LEZ-compliant, so there is no charge line on your invoice anywhere in London — including on multi-day fit-out programmes.
Power, water and lighting on site
We need a working socket and a cold tap. If the supply is not commissioned yet, tell us at booking and we bring a battery HEPA setup, task lighting and water containers rather than losing half a day.
Walk-up and stair access
Lift or ground-floor access here, so no stair-carry allowance is needed in the timing.
Concierge, goods lift and site sign-in
We register the team with the concierge, book the goods lift and complete the building's contractor sign-in before the visit, at no cost to you.
Working around remaining trades
If the decorator, electrician or flooring fitter is still finishing, we sequence rooms behind them and hold the sparkle pass until they are off site. The programme is agreed with your project manager, not guessed at.

This housing stock

Where construction dust hides in Merton homes

Edwardian villas in Wimbledon, 1930s semis in Raynes Park and Morden, and estates around Mitcham. That stock decides where construction dust ends up across the borough, so these are the places we go first.

Radiator fins, backs and the wall behind them

Plaster and sanding dust falls straight into a radiator and then gets blown around the room the first cold evening. Fins are cleared with a purpose-made brush and HEPA extraction rather than a cloth over the front.

Door tops, architraves and boxing-in ledges

Every horizontal edge above eye level is a shelf for fine dust, and it is the one thing a client always runs a finger along. Each ledge is vacuumed first, then wiped, then checked again after the second fall.

Bifold and sliding-door tracks and drainage channels

New tracks fill with mortar grit and silicone crumbs during glazing, and if it is left the door jams within weeks. Channels are vacuumed, flushed and the weep holes proved clear.

The rooms the extension opens onto

Dust travels the length of the house through a knock-through. The original kitchen, hallway and stairs need the same passes as the new room, and that is inside the quote rather than an extra.

Roof lights, reveals and steel beam boxing

Lantern lights and flush roof lights are cleaned from a pole with the frames and gaskets, and the fresh plasterboard boxing around the steel is dusted before it is wiped so nothing is dragged across new paint.

Garden thresholds, patio and the spoil route

The route materials took through the side return holds mortar splash and plaster runoff. We wash the threshold, cills and hard landscaping so it is not walked back into the new floor.

About the borough

Merton in context

Wimbledon's village and tennis, Mitcham's commons and the Wandle valley industry at Colliers Wood. Merton Priory and Wandle mills gave way to Victorian and interwar suburbs once the railway reached Wimbledon in 1838.

Edwardian villas in Wimbledon, 1930s semis in Raynes Park and Morden, and estates around Mitcham. On ONS Census 2021 figures the borough holds 81,726 households with a median age of 37, 56.7% owner-occupied and a dwelling split of 39.6% flats to 60.4% houses — the mix that decides what gets built here and how a builders clean is scoped.

Access sets the day's programme. Championship-fortnight restrictions in SW19, hill access to Wimbledon Village, and driveways common further out. London Borough of Merton permits, suspensions and dispensations are arranged and paid for by us, and any cost sits inside the quoted price.

Colliers Wood is mostly unlisted stock outside conservation control, which means extensions, loft conversions and internal knock-throughs rather than restoration work — and dust that has travelled through the whole house rather than being confined to one wing.
