Tens of thousands of visitors tramp up Peascod Street and past the castle on a busy weekend, and every one of them is grinding a little grit into the pavement that ends up on your floor by Sunday night.
Windsor lives with footfall most towns never see, and carpets here take the brunt of it. A hoover skims the top. The dirt that turns a pale carpet grey sits right down at the base of the pile, below where the brush can reach, and getting that bottom layer out is the whole job.
Last updated April 2026. Written by the owners of Monster Cleaning Ltd, who have cleaned carpets across Windsor and the SL4 postcode since 2014.
We clean carpets in Windsor by hot-water extraction, from £36 a bedroom.
That is the answer nearly everyone rings up with, and the full price list is a short way down. The rest is the honest detail: how the machine works, the stains we will not swear to, and a fair bit about the actual floors we meet around this town.

There are two Windsors, and they wear their carpets differently.
There is the town the tourists see: the castle, the Long Walk and the shops below the Royal Station. Then there is the town people actually live in, which runs west through Clewer and Dedworth and is where most of our bookings sit.
The first brings the footfall. The second is where that footfall ends up trodden into a hall carpet.
- Close to the centre
- The housing is old. The streets behind St Leonards Road and around Clewer Green are full of Victorian and Edwardian terraces, the proper period stock, and a good number have been carved into flats over the years. They almost always come with steep, narrow stairs, and stairs are the single hardest thing in any house to clean well, because every footfall lands the dirt on the front lip of the tread rather than spreading it about.
- Dedworth and the roads off Dedworth Road
- Mostly inter-war and post-war semis, sturdy 1930s and 1950s family houses with gardens. Families, dogs, a hall that doubles as a boot room. The carpet tends to be a hard-wearing synthetic that has quietly soaked up decades of school runs, dogs and muddy boots. These are our bread-and-butter jobs, and a hall gone grey wall to wall usually comes back looking years younger.
- Down by the water
- The newer riverside flats and converted blocks near the Brocas and the Datchet Road end are mostly lets and second homes, often with short builder-grade carpet that takes a hot rinse without any fuss.
- The bigger detached houses near the Great Park
- Here you meet wool and wool-mix in pale colours, which shows every coffee ring and every paw print back from a walk. The job there is keeping ahead of the wear rather than hauling a wreck back from the dead.
A hoover skims the top. The dirt that turns a pale carpet grey sits right down at the base of the pile, below where the brush can reach, and getting that bottom layer out is the whole job.
How we actually clean a carpet
The method is hot-water extraction. Most people call it steam cleaning, even though there is next to no steam in it. Once we are through your door, it goes like this.
- We vacuum first, slowly and properly, because dry grit lifts away far more easily before it gets wet. Skipping that step is how a rushed job grinds mud down into the pile.
- We put down a pre-spray, picked to suit the fibre and how dirty the carpet honestly is, and leave it to work. Those few minutes of dwell time are where the soil lets go. Rush it and all you have done is wet the floor.
- Then comes the machine. Hot water goes down into the pile under pressure and is drawn straight back out on the same stroke, lifting the loosened dirt with it, while a strong vacuum pulls most of the moisture so the carpet is left damp rather than soaked.
- On the worn lanes, those grey channels tramped into a hall by years of trips to the front door, we go over a second time and groom the pile so it dries standing up rather than flat and matted.
We will not flood your floor.
We also carry public liability cover, so on the rare day something goes wrong in your home, you are not the one left out of pocket. You should never let anyone push water through your floors without it.
What it costs
Prices are per room or per area, with no quote form needed for the everyday rooms. We work in whole rooms, because half-cleaning a carpet only leaves you a tide mark across the middle of the floor.
- A single bedroom
- £36
- A living room
- £43
- A through-lounge
- £61. It is the knocked-through front-to-back reception you find in a lot of the older terraces, and it costs more because it is really two rooms in a trench coat.
- Stairs
- £41 a flight, cleaned by hand one tread at a time
- A rug up to 3m2
- £35
- A larger rug over 3m2
- £51
- A whole carpeted two-bed property
- £135, far and away our commonest booking around here
If the job is an odd shape, we can work by the hour instead:
- a landing on its own
- a box room
- one set of stairs and nothing else.
Now and then that comes out cheaper than adding up a string of small rooms. Tell us what you have got over the phone and we will say which way works out better for you.
That is the whole price. We do not run a fake high number with money knocked off to look generous. What we say on the phone is what you pay at the door.
Carpet cleaning sits alongside the rest of what we do in the town. If you are moving out and the whole place has to pass an inventory check, our end of tenancy cleaning in Windsor rolls the carpets in with everything else.
People often add an oven deep clean in Windsor onto a carpet booking, and for the regular upkeep there is our domestic cleaning in Windsor round. You can also read up on the kit and the method on our main carpet cleaning service page.
Drying, and what to do afterwards
A carpet that has been extracted properly is damp, not wet. Same day, the room is usually back in use.
- Walkable
- Most rooms are fine to walk on within a few hours.
- Properly dry
- Inside about half a day.
- Slower
- Wool and thick pile hold more water and take longer. A cold flat shut up in February dries slower than the same flat in June with a window open.
What helps afterwards:
- Open a window if you can, and a fan aimed across the floor speeds the whole thing along no end.
- Keep shoes off until it is dry.
- If you must cross a damp carpet, wear clean socks, because bare feet leave oils that turn into fresh marks.
We slip little foam blocks under furniture legs so a drying carpet cannot pick up rust or a stain off the wood.
Stains, and what we will not promise
This is where a lot of carpet cleaners oversell, and we try hard not to. A stain and general dirt are two different problems.
- General dirt
- Overall soiling, worn traffic lanes, a tired grey cast across a whole floor: that lifts well nearly every time.
- A single set-in stain
- A coin toss, and which way it lands comes down entirely to what it is and how long it has been sitting there.
- Shifts most of the time
- Mud off the Long Walk, tea, food, washable drinks, everyday grime.
- Digs in and fights you
- Dried red wine, old pet accidents soaked down into the underlay, dye creeping out of a cheap rug, anything with bleach in it that has already pulled the colour out of the pile.
Bleach by that point is not really a stain at all. It is missing carpet, and no machine on earth puts the colour back.
So you get a straight answer and a range from us. Guessing high to win the booking and then shrugging on the day is exactly the trick that gives carpet cleaners a bad name, and we would sooner lose the job than do that to anyone.
When we arrive we tell you what we expect to clear and what we expect only to improve.
If a stain is going to give us trouble, we say so before the machine comes out, not after the money has changed hands.
Windsor water, and why it matters to us
Windsor has properly hard water, and it changes how carefully we rinse.
The supply comes from Affinity Water, drawn up out of the chalk that sits under this whole stretch of the Thames Valley, and chalk is what makes water hard. It is the same calcium that fills your kettle with scale and leaves a chalky ring round the showerhead.
You notice it on the bathroom taps long before you notice it in a carpet. Where it matters to us is the rinse: hard water needs the right balance of product and thorough extraction, or a pile can dry stiff and a touch chalky to the hand. So we:
- watch how much water and product goes in
- extract hard at the end.
That is why a carpet we have finished is left soft underfoot rather than crisp. It is a small thing, but it is the difference between a carpet that feels clean and one that just looks it.

0333 555 2076 · 8am to 7pm
Give us a ring on 0333 555 2076, or email office@monstercleaning.com with:
- your postcode
- the rooms you want done
- a line about any stains you are worried about.
A quick photo of a bad patch helps us tell you whether it is worth a go. We come back with a real price, not a vague band, because the prices are already up above and we hold to them.
We cover Windsor right across the SL4 postcode and the villages around it:
- the streets under the castle
- Clewer and Dedworth
- the riverside flats by the Brocas
- out toward Old Windsor and Datchet.
- One heads-up if you live near the middle
- A fair few streets, Clewer Fields among them, sit inside resident permit zones. Since the borough went to virtual permits in 2024 there is no paper voucher to hand the driver, so tell us when you book and we will sort where the van goes.
Monster Cleaning Ltd is based at 75 Shakespeare Avenue, Feltham, TW14 9HU, and we have been at this since 2014. The van comes to you.
Frequently asked questions
How much is carpet cleaning in Windsor?
A single bedroom is £36, a living room is £43, and a whole carpeted two-bed property is £135. A flight of stairs is £41 and a through-lounge is £61. A rug up to 3m2 is £35 and a larger rug over 3m2 is £51. Those are full prices with nothing tacked on for coming out to SL4.
Is this steam cleaning or hot-water extraction?
It is hot-water extraction, which is what most people mean when they say steam cleaning, though there is hardly any steam to it. We pre-spray to loosen the soil, then push hot water into the pile under pressure and pull it and the dirt straight back out on the same stroke.
How long does a carpet take to dry?
Most rooms are walkable within a few hours and properly dry in about half a day. Wool and thick pile hold more water and take longer. A flat shut up cold in February dries slower than one with a window cracked, so open a window and aim a fan across the floor if you can.
Will you get every stain out?
No, and anyone who swears they will is guessing. General soiling and the worn grey lanes lift well almost every time. A single set-in stain is a coin toss that turns on what it is and how long it has sat. We tell you on arrival what we expect to clear and what we expect only to fade.
Does the hard water in Windsor change how you clean?
It does not leave the carpet worse, but we rinse around it. Windsor sits on chalk and the supply from Affinity Water runs hard, the same stuff that furs up your kettle. We watch how much water and product goes in and extract hard at the end, so a finished pile is left soft underfoot rather than stiff.
Can you clean carpet on steep Victorian stairs?
Yes, and plenty of the older terraces around Clewer have exactly those. Steep narrow stairs are the hardest part of any house, because the dirt lands on the front edge of each tread where the foot drops. We clean them by hand with a stair tool, one tread at a time.
Do I need to move the furniture first?
Move the small and breakable bits and lift what you can off the floor. We will slide sofas and chairs across to clean under them and pop foam blocks under the legs while it dries. We do not shift beds, full wardrobes, or anything heavy, so just clear what you reasonably can.
Do you clean rugs as well as fitted carpets?
Yes. A rug up to 3m2 is £35 and a bigger rug over 3m2 is £51. We clean rugs flat on your own floor at home. Tell us the type when you book, because a handful of old or delicate wool rugs are a job for a rug restorer instead, and we will say if yours is one of them.
Which parts of Windsor do you cover?
All of it across the SL4 postcode and the edges around it. That takes in the streets below the castle, Clewer and Dedworth to the west, Dedworth Road and the estates off it, the riverside flats by the Brocas, and out toward Old Windsor and Datchet. The van comes to you.
How do I book, and is there parking near the centre?
Ring 0333 555 2076 or email office@monstercleaning.com with your postcode and the rooms. If you are in one of the resident permit zones like Clewer Fields, let us know, because the borough went to virtual permits in 2024 and a quick word saves the van hunting for a legal space.
Do you offer a re-clean guarantee?
Not on carpet cleaning. The 48-hour re-clean guarantee is for end of tenancy cleans. If anything about your carpet clean concerns you, ring us on 0333 555 2076. We also carry public liability cover, so on the rare day something goes wrong in your home you are not the one left out of pocket.
