An inventory clerk walking a Roundshaw house starts at the window reveals, because these are tight, well-sealed homes and the cold corners are where the black spot shows. That one habit shapes everything about a hand-back clean on this estate, the one built over the old Croydon Airport runway off Mollison Drive and Lindbergh Road.
We are Monster Cleaning, a domestic end of tenancy team working Roundshaw and the rest of Wallington, cleaning to a 57-point agent-approved checklist at a fixed price by bedroom count, with a 48-hour re-clean guarantee if anything is flagged. Ring 0333 555 2076 for a price.
Last updated June 2026. We cover the whole Roundshaw estate and the Wallington streets around it, SM6 9 and the wider SM6, plus the Beddington and Waddon fringe toward Croydon. This page sits inside the borough directory at End of Tenancy Cleaning Sutton.

Most people in Roundshaw do not lose deposit money because the home was dirty. They lose it because the check-in inventory was thorough and the check-out is read against it, line by line and photo by photo.
- When you moved in, a clerk walked the place and wrote down the state of every surface, usually with dated pictures, usually marking the kitchen and bathroom as clean or as new. That was true on the day, because the home had just been turned around for you.
- At the end, a clerk walks it again and compares.
- Anything worse than the check-in entry, past fair wear and tear, can be charged against your deposit.
The estate is let by a mix of landlords, and that mix matters for how strict the inspection is.
- The housing association
- A good chunk of Roundshaw is managed by the housing association that ran the rebuild. The association is watching void turnaround and will note anything that holds up a relet.
- Private landlords
- Alongside it sits a steady pool of private landlords who bought former association homes and now let them out. The private landlord is protecting a deposit held in a scheme and leans on the photographs.
Both commission a proper inventory. Neither is the softer option, and you rarely know in advance which one is coming, so we clean to the stricter as a matter of course.
The law sits behind all of it and it has not loosened. Your landlord cannot deduct for fair wear and tear, and the deposit must be held in a government-approved scheme, with the rules on protection, deductions and disputes set out on gov.uk.
But dirt, grease, scale, or a mould bloom that started during your tenancy stays chargeable if the check-in recorded the home clean. If it goes to dispute, the clerk’s dated photographs are what an adjudicator reads.
The whole job of a hand-back clean is to make the check-out pictures match the check-in pictures.
A runway under the houses: what the estate is actually made of
Roundshaw is built on part of the old Croydon Airport, which was the United Kingdom’s main international airport between the two world wars before it closed in 1959. The streets carry the history openly, all named for the aviators, aircraft and firms tied to the airfield:
- Mollison Drive
- Lindbergh Road
- Olley Close
- Avro Way
- Brabazon Avenue
The grassland on the eastern edge, Roundshaw Park and the open space beyond it, is the surviving airfield. A stretch of the original runway tarmac is still there under the grass, walked by dog owners and used by the model-aircraft flyers and the Croydon Pirates baseball team.
It is pleasant to live next to. It is also the reason ground-in grass and mud down a hallway and into stair carpet is a genuine Roundshaw write-up after a wet winter.
The housing itself is younger than the street names suggest, and that is the fact that decides the deduction list.
- From 1965
- The original estate went up, designed by the architects Chamberlin, Powell and Bon, as concrete system-built blocks and maisonettes. Those did not last.
- From 1998
- The concrete stock was demolished phase by phase, and Instone Close was imploded in November 2000.
- The rebuild
- Roughly a thousand new low-rise brick houses and flats went up in their place, while 674 older brick homes that were never the concrete type were kept and re-roofed with pitched roofs.
- 2010
- The regeneration finished.
So whether you are in a newer house or a refurbished older one, what you hand back is, in almost every case, a modern or modernised brick home with double glazing and a tight, well-insulated shell.
Tight, warm homes that get dried-out washing in winter grow black spot in the corners. That, not grime, is the classic Roundshaw deduction.
That sealed shell changes what goes wrong. There is no picture rail full of dust, no original plasterwork quirk, no draughty box to hide behind. What there is instead is condensation.
A warm, well-sealed home where washing is dried indoors over winter puts moisture into the air, and it settles on the coldest surfaces:
- the corners of bedrooms
- the reveal of a window
- the wall behind a wardrobe pushed against an outside face
Black spot comes up there. Add the ordinary wear of a family tenancy and you have the four lines that come back deducted here over and over:
- black spot in those cold corners
- grease across the kitchen units
- scuffed emulsion on the stairs
- carpet gone flat and grey in the traffic lanes
The water here is not quite what you have been told
Plenty of people will tell you Sutton has hard water and leave it there. It is worth being precise, because the detail changes how you clean a Roundshaw bathroom.
- The supplier
- SES Water, which is unusual among UK suppliers in that it partially softens its borehole water at the works, taking it, in their own words, from a hard level down to a medium one.
- What reaches SM6
- Moderately hard, not the brick-hard supply you get a few miles north under Thames Water.
- Late 2025
- Roundshaw residents got a sharp reminder when the softening plant at the Cheam works that feeds this area went down for repair. The supply ran much harder than usual, and the scale on screens and kettles jumped accordingly.
Medium does not mean scale-free. SES say plainly that because they do not remove all the hardness, there is still potential for limescale to form, and on shower glass, taps and a kettle it does.
A clerk does not need the plant to fail to find it, though. They run a thumbnail across a tap and look at the shower screen edge-on against the light, and a cloudy film you stopped noticing two years ago is the first thing they see.
So descaling the bathroom is part of the standard clean here, not something to skip.
The 57 points, room by room, and the streets we cover
Every booking runs to the 57-point checklist, worked in the order the home is inspected rather than a random sweep. We cover the whole estate and the streets that feed it:
- Mollison Drive and the closes off it
- Lindbergh Road and the aviation-named turnings around it
- the newer terraces backing onto Roundshaw Park
- the retained pitched-roof homes nearer the Wallington edge
- the flats and maisonettes on the regeneration blocks
- out across the Beddington Lane and Hilliers Lane fringe toward Waddon
If your address is in SM6, we clean it. Here is what the clean is, folded into the rooms where deposits are won and lost.
The kitchen, where most of the money sits
Roundshaw kitchens are fitted, with integrated appliances, so grease builds where you push things in and where you cannot see.
- We degrease the unit doors, handles, the splashback, the tiles and the side panels.
- The oven, an add-on from £31, is cleaned rather than wiped: racks out to soak, the brown film between the panes cleared where possible, the liner, the fan, the seals by hand.
- The hob and any extractor canopy are degreased and the filter soaked or swapped, because the clerk tilts that filter to the light.
- We pull the fridge-freezer and the washer out where they move, clean behind and down the sides, and do the seals, the washer drawer and the drum.
- Cupboards and drawers wiped inside, sink and taps descaled, bin washed.
The bathroom, where the water shows
The moderately hard supply still leaves a film, so the bathroom is largely a descaling job.
- The shower screen and tiles come back to clear.
- Scale lifts off the taps, the showerhead and the spout.
- The grout and sealant get scrubbed and checked for the first signs of mould.
- The toilet is cleaned and descaled under the rim and around the base.
- The extractor vent dusted, the mirror and any cabinet done, and the floor washed into the edges.
- An over-bath screen gets both faces.
Bedrooms, the living room and the stairs
This is where the sealed-home problems live. We treat and clear any condensation mould in the corners and along the cold window reveals rather than wiping it so it greys back in a fortnight, which is the difference between a pass and a callback on this estate.
- Flat emulsion is spot-cleaned for scuffs where furniture and the stairs have taken a knock.
- Skirtings, the tops of doors and the frames, switches and sockets all wiped.
- Built-in wardrobes done inside and out.
- Windows cleaned inside with the sills and the reveals included, because the reveal is exactly where the torch goes.
Carpets, glass and everything else
Every hard floor is washed into the edges and corners, and carpets are vacuumed thoroughly.
Where the inventory photographed the carpet clean and the traffic lanes have since gone flat and grey, a carpet shampoo is the add-on that protects that line. On a family let backing onto the open space, with grass and mud worked into a hallway, it usually earns its keep.
We also do:
- the internal glass
- the airing cupboard
- the consumer-unit cupboard
- radiators and behind them
- the loft hatch surround
- the cobwebs off the ceiling line
Flats and maisonettes on the regeneration blocks have a shared entrance and a short internal landing the inventory recorded. That communal-facing strip is part of what the clerk photographs, so we clean it rather than stopping at your own front door.
What it costs, and the sum nobody does in time
Pricing is fixed by the size of the home, not run off a meter on the day. A studio is £156 and a one-bed flat £207. A two-bed, which is the bulk of Roundshaw, is £243, a three-bed house £339, and a four-bed £425.
If you would rather book by the hour for an odd or partial job, it is £30 per cleaner.
The add-ons are quoted in plain numbers too, so nothing appears on the invoice that was not on the quote.
- Carpet shampoo
- £29 a bedroom, £36 for a living room, or £94 for two bedrooms and a living room done through.
- Oven, with the end of tenancy clean
- £31 a single and £62 a double or 90cm range.
- Oven as a standalone
- £77 for a single, £110 for a double and £143 for a 90cm range.
The mould treatment and the descaling are part of the clean, not surcharges. The only time a price moves off the table is an unusually large house or one left in heavy condition, and we agree that figure before we start.
Run the sum the way the deposit makes you, because most people only run it after they have failed a check-out and lost the first round. A two-bed clean at £243 set against a deposit of a couple of thousand pounds is not really a decision.
Every booking carries a 48-hour re-clean guarantee. If the clerk or the housing association flags a cleaning point we listed, we come back within 48 hours and put it right at no charge, as long as:
- you tell us inside that window
- nobody has moved in yet
There is a reason agents and managers around here use us. We are on the books of 300+ letting agents across London and Surrey, and over the years that work has helped tenants hold on to £1.2m in deposits that would otherwise have gone on cleaning deductions.
Laid out, a typical Roundshaw job looks like this.
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio flat | 3-4 hours, 1 cleaner | £156 |
| 1-bed flat or maisonette | 4-5 hours, 2 cleaners | £207 |
| 2-bed flat or house (most of the estate) | 5-6 hours, 2 cleaners | £243 |
| 3-bed brick house off Mollison Drive | 6-7 hours, 2 cleaners | £339 |
| 4-bed house | 7-9 hours, 2-3 cleaners | £425 |
What the clerk opens first, in order
The clerks and association surveyors who cover SM6 go through a home in a fairly fixed order, and knowing it tells you where the deposit is actually decided.
- The kitchen comes first, every time: the oven door glass and the inside, the extractor filter tilted to the light, the gaps behind and beside the fridge and washer, the cupboard interiors and the seal of every appliance.
- Then the bathroom, where the shower glass and screen are checked edge-on for that scale film, the grout and sealant for mould, and the showerhead and under the toilet rim go under scrutiny.
- From there, the bedroom walls and the window reveals, where the corners and the cold reveal get the torch, because condensation mould is the most common write-up on this estate.
- After that, the paintwork on the stairs and high-traffic walls, scuffs held against the check-in shots.
- Then the carpets in the traffic lanes and by the doors, flattening and greying compared with the move-in pictures.
- Last come the skirtings, door tops, sockets and switches, and the communal-facing entrance or shared landing on the flatted blocks.
Our checklist follows that running order deliberately, so the home is finished in the sequence it gets inspected.
Which clean you actually need
People muddle three different jobs, and booking the wrong one wastes money. A quick run through the distinction, because only one of them gets a deposit back.
- Check-in inventory
- The report a clerk writes on day one, with photos, describing every surface. It is the benchmark your check-out is judged against, which is why we clean to it and not to a vague idea of tidy.
- End of tenancy clean
- The full hand-back reset, built to pass that inventory and release the deposit, done with the home empty and the 48-hour guarantee on it. This is the one you need when you leave Roundshaw.
- Deep clean
- A heavy one-off for a home you are staying in, with no clerk to satisfy and no formal standard to hit.
- Regular domestic clean
- Ongoing weekly or fortnightly upkeep of a home you live in, a different service with a different rate.
Booking it, and the month-end rush across Wallington
Booking is short. Call 0333 555 2076 or email office@monstercleaning.com with:
- your Roundshaw address
- the block or street
- the number of bedrooms
- your check-out date
- We send a fixed quote the same day, with any carpet or range-oven add-on priced in, and there is no inspection visit to arrange first.
- We confirm a slot, ideally the day before your check-out so the home is clean when the clerk arrives.
- We remind you to leave the water and power on.
- We clean to the 57-point checklist and message you when it is done with the photo set.
- If anything is flagged, we are back inside 48 hours.
Two timing notes are specific to here.
Access on the estate
The estate has effectively one main way in and out, and the newer terraces are laid out around pedestrian courts and parking squares rather than a road you can pull straight up to. A removals van and a cleaning crew can want the same few bays at the same time.
Tell us your move slot when you book and we either come the day after the van has gone or time our arrival so the kit is carried in without a long haul across a court.
We can clean around you if the move runs late and finish the last room once it is clear, though an empty home always cleans to a higher finish.
The calendar
The end of the month is busy right across Wallington as tenancies turn over together. Roundshaw has a high churn of association and ex-association lets where void inspections tend to be scheduled in clusters, so a single week can get tight across the whole estate at once.
Two or three days’ notice is usually fine mid-month; for a check-out on or near month-end, give us a week if you can.
The Renters’ Rights Act 2025, which came in on 1 May 2026 and ended Section 21 while converting older tenancies to periodic ones, has not changed the clean itself. By letting people leave on rolling notice, though, it has made move-out dates less predictable, which is one more reason to book early.
Questions we get asked
How much is end of tenancy cleaning in Roundshaw?
A studio is £156, a one-bed £207, a two-bed £243, a three-bed £339 and a four-bed £425. Most Roundshaw homes are two and three-bed brick houses and flats, so £243 to £339 covers the bulk of the estate. A part property or an unusual layout is £30 per cleaner per hour.
Do you guarantee the clean if the inventory clerk is not happy?
Yes. We hold a 48-hour re-clean guarantee. If the clerk or the housing association flags any cleaning item we listed, we come back within 48 hours and put it right at no extra cost, as long as you tell us inside that window and nobody has moved in.
Why does mould keep coming back on my Roundshaw walls?
Because the rebuilt homes are sealed and well insulated, moisture from cooking, showering and drying washing indoors settles on the cold corners and window reveals and grows black spot. Wiping it just takes off the surface. We treat it so it goes back to the check-in condition instead of greying back in a fortnight, which is the most common thing that decides a Roundshaw deposit.
Is the water here actually hard?
It is moderately hard rather than fully hard. SES Water supplies the area and is unusual in that it partially softens its borehole water at the works, taking it from a hard level to a medium one. Scale still forms on glass, taps and kettles, which is why descaling the bathroom is a standard part of the clean. Residents noticed extra scale in late 2025 when the softening plant feeding this area was down for repair.
Do you clean the older retained houses as well as the new builds?
Yes. The estate has roughly a thousand new low-rise brick homes from the regeneration plus 674 older brick homes that were kept and re-roofed with pitched roofs. We clean both to the same 57-point checklist, and the recurring issues, grease, condensation mould, scuffed paint and worn carpet, are much the same across the estate.
Is the oven included or charged on top?
Charged on top of the end of tenancy price. We clean the oven, soak the racks, and do the door glass (between the panes where the door allows) and the liner, and degrease any extractor and its filter. With the clean an oven is £31 for a single and £62 for a double or a 90cm range; as a standalone service it is £77, £110 and £143.
Should I add a carpet shampoo?
On Roundshaw it usually pays off. The homes are carpeted in the bedrooms and on the stairs, the inventory photographs them at check-in, and after a family tenancy the traffic lanes go flat and grey, often with grass and mud worked in from the open space. A vacuum will not lift that. Carpet shampoo is £29 a bedroom, £36 a living room, or £94 for two bedrooms and a living room.
Can you clean around me if I am still moving out?
Yes. The estate has one main way in and out and moves can run late, so we work around boxes and do the last room once it is clear. We would still rather come the day after you have fully moved if the timing allows, because an empty home cleans to a higher finish.
How does the Renters’ Rights Act 2025 affect my deposit?
Your landlord still cannot deduct for fair wear and tear, but cleaning, grease, scale or a mould bloom that started during your tenancy is still chargeable if the check-in recorded the home clean. The clerk’s dated photos are what an adjudicator reads, which is exactly why a hand-back clean that matches the check-in shots protects you. Shelter sets out the deposit and deductions rules at Shelter’s tenancy deposits guidance.
Does Sutton Council licensing affect tenants in Roundshaw?
Mostly it affects landlords. Sutton brought in a borough-wide additional HMO licensing scheme from 22 March 2026, covering shared houses not already caught by mandatory licensing, so if your Roundshaw home is let room by room your landlord likely needs a licence. It does not change your cleaning obligation at the end of the tenancy, but a licensed landlord tends to commission a stricter inventory. The scheme is set out on sutton.gov.uk.
How far ahead should I book, especially for month-end?
Two or three days is usually enough mid-month, but the end of the month is busy across Wallington as tenancies turn over together, so give us a week if your check-out is on or near month-end. Roundshaw has a high churn of association and ex-association lets, and those void inspections tend to be scheduled in clusters, which means a particular week can get tight across the whole estate at once. If you already have a check-out date from your landlord or the association, give us that date and we will hold the slot the day before it.
What if my home is bigger than four bedrooms or in poor condition?
Tell us when you call and we will quote it specifically. The table covers studios to four-beds in standard condition. An unusually large house, or one left in heavy condition after a long tenancy, gets its own fixed price agreed before we start, so there is no surprise on the day.
