- 72-hour re-sparkle promise on every clean
- Royal Borough of Greenwich permits and ULEZ inside the price

After builders cleaning in Blackheath SE3
Extensions and loft conversions around Blackheath and the Paragon push dust through the whole house, so a SE3 builders clean here is never just the new room: the original kitchen, the hallway, the stairs and every radiator in between are inside the quote.
Most Blackheath bookings follow a rear extension, side return or loft conversion, which means the dust has travelled through the whole house rather than sitting in one room. We quote the original rooms and the staircase alongside the new space, sequence the clean behind the flooring fitter and the decorator, and hold the sparkle pass until the snagging trades are off site. With 48.4% of Greenwich homes being houses, that is the normal shape of the job here.
Typical works here: rear extensions, side returns and loft conversions. Access and parking: Conservation-area restrictions, narrow village streets and listed staircases.

- 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. Greenwich is outside the Congestion Charge zone.
- Royal Borough of Greenwich 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 Blackheath from programme to sign-off
- 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.
- 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.
- 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.
- 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.
- 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 Blackheath 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 Blackheath
Conservation-area restrictions, narrow village streets and listed staircases. An extension or loft in Blackheath 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
3 stages · 26 checked items · every one of them in Blackheath SE3
Stage 1 — builders' rough clean
2–5 hrsAs 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 daysOnce 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 hrsHandover, 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 Blackheath SE3
| Add-on | From | Time | Detail |
|---|---|---|---|
| Builders' waste and packaging removal | £90 | 45–90 min | Offcuts, 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 | £55 | 40–60 min / room | Dry 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 | £75 | 1–2 hrs | Reach-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 | £60 | 60–90 min | pH-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 | £65 | 60–90 min | Blade 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 | £45 | 30–45 min | Grilles, 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 | £120 | 2–4 hrs | Booked 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 | £95 | 1–2 hrs | Jet 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 clean | Included | included | Film, 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
- Conservation-area restrictions, narrow village streets and listed staircases. Any permit, bay suspension or dispensation in Royal Borough of Greenwich'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
- Greenwich 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
- No managed-building sign-in needed at most addresses here; tell us at booking if your block runs a contractor induction.
- 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 Blackheath homes
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 area
Blackheath in context
Ask anyone in SE3 what marks Blackheath out and Blackheath and the Paragon comes up first. The heath, the village and Georgian terraces facing open grass. Royal palace and naval hospital on the river, arsenal at Woolwich; the Peninsula's gasworks became the O2 and new districts.
Georgian crescents such as the Paragon, Victorian villas and 1930s houses. With 289,068 residents across 114,051 households and a median age of 34.8 (ONS Census 2021), Blackheath sees a steady run of improvement work rather than one-off projects — and every one of them ends with the same fine grey layer over a finished room.
Access decides how the programme is scheduled. Conservation-area restrictions, narrow village streets and listed staircases. Greenwich sits outside the Congestion Charge zone and inside ULEZ. We confirm Royal Borough of Greenwich's controlled parking position for the exact street before the booking is fixed, and any permit or bay suspension sits inside the quoted price.
Much of Blackheath sits in a conservation area, so windows, joinery and stonework are original or like-for-like replacements. We treat every surface as irreplaceable: no caustics on painted timber, no blades on soft old glass, and a test patch before anything stronger than water goes near a finish.

Questions
Blackheath SE3 after builders cleaning questions, answered
A single-room refit in Blackheath is £145 on a protected site and £185 after a normal builders' aftermath. A rear extension or loft is £265 to £335, a whole flat refurbishment £315 to £395 and a 3-bed house £425 to £525. That includes M-class HEPA dust removal, protective film and label removal, grout haze and paint specks, new appliance interiors, and every parking, permit and ULEZ cost in Greenwich.
A deep clean tackles grease, limescale and lived-in soil in an occupied home. An after builders clean tackles fine construction dust, protective film, adhesive labels, grout haze, paint specks and silicone smears on finishes that are brand new and easily damaged. Different machines, different chemistry, different order — and it is done in stages because fine dust settles twice.
Yes, and most projects need it. Stage 1 is a rough clean so the site stays workable during second fix. Stage 2 is the full post-construction clean once every trade is off site. Stage 3 is the sparkle on handover, photography or move-in morning. You can book one stage, two or all three.
A single room is three to four hours, an extension or loft six to eight, a whole flat seven to ten and a 3-bed house one to one and a half days. Most Blackheath bookings follow a rear extension, side return or loft conversion, which means the dust has travelled through the whole house rather than sitting in one room. We book the hours the property actually needs rather than a fixed slot.
Because construction dust is fine enough to stay airborne for hours and it falls again once you open a door or run the heating. That is why the main clean is two passes and why we offer a sparkle stage timed to handover, plus a 72-hour window to call us back free if it settles again.
Regularly. We take purchase orders, complete site inductions, work to a programme, invoice the contractor or developer with VAT and a PO reference, and provide photographic room-by-room sign-off for the client file. Multi-plot and repeat-site rates are agreed in advance.
No. Conservation-area restrictions, narrow village streets and listed staircases. Where Royal Borough of Greenwich operates a controlled parking zone at your address we check the hours at booking and arrange a visitor permit, a suspended bay or a dispensation ourselves. You are never asked to buy one and it is not added to your invoice.
Blackheath is inside the ULEZ but outside the Congestion Charge zone. Our vehicles are ULEZ- and LEZ-compliant and any charge is already inside the fixed price.
Book the main clean after the flooring and decorating are complete, and the sparkle for the day you move furniture back in. Cleaning before the decorator finishes simply pays for the same room twice.
A working socket and a cold tap, ideally. If the supply is not commissioned we bring battery HEPA machines, task lighting and water containers instead — just tell us at booking so the right van is loaded.
Often, yes — handover dates move and we plan for it. Next-day slots carry no premium and weekends cost the same as weekdays. Genuine same-day call-outs are +£40 and depend on a team being free; call 020 3633 4555 for same-day availability.
Yes — every street in SE3, including Blackheath and the neighbouring Greenwich areas. Boundary postcodes are covered too; enter your full postcode in the quote form and it confirms coverage instantly.
Packaging, protective sheeting, offcuts and light debris can go with us from £90 a van load under our upper-tier waste carrier registration, and you get a waste transfer note. Rubble, plasterboard, tiles and anything hazardous have to leave via your contractor's licensed disposal route.
That is the risk we design the service around. Every product is matched to the finish and test-patched, blades are used only where the manufacturer allows, caustics and abrasives stay in the van, and we follow the care sheets for new oak, resin, terrazzo, quartz and freshly painted plaster. If something cannot be cleaned safely we tell you in writing rather than gamble.
