Most Windsor ovens fail on the same thing: the inner door glass. A grey film of baked grease over a chalky haze of limescale, and behind it carbon flaking off the roof of the cavity onto whatever you are trying to roast. We strip the oven down on your kitchen floor, soak the shelves and the lift-out panels in a heated tank in the van, and put the lot back together the same afternoon. No caustic fumes, no leaving it overnight with the back door wedged open.
Last updated April 2026. The prices here are what we charge in the SL4 postcodes, not a teaser figure that swells when the cleaner is stood in your kitchen.
We clean ovens across Windsor and the SL4 postcodes, single ovens from £77, with a non-caustic dip-tank and the oven back in use the same day.
What an oven clean costs in Windsor
Flat prices, written down plainly so you can see the lot before you ring. A single oven is £77. A double, which is what a surprising number of Windsor kitchens turn out to hide once you actually open both doors, is £110. A 90cm range cooker is £114, and a two-oven AGA is £143, because that one is slower and the enamel wants a careful hand.
The add-ons cost the same whether you bolt them onto an oven booking or have them done on their own. A hob is £23 to £28, depending on whether it is a ceramic top to wipe over or a gas hob with cast trivets and burner caps that all come apart in the tank. An extractor is £28. A microwave is £22.
That is the whole list. No call-out fee tacked on the end, no cheaper number on the phone and a dearer one at the door. What you read is what you pay.
The van dip-tank, and why we skip caustic
The real graft happens in a heated tank out in the van, not on your worktop. We lift out the shelves, the side runners, the inner door glass and any panel that comes away, and they go in to soak while the cavity, the rubber seal and the fan housing get cleaned by hand. The tank runs a non-caustic dip-tank solution, not the caustic soda a handful of firms round here still swear by.
Does the difference matter? It does, for two flat reasons. Caustic bites into aluminium trim and dulls vitreous enamel a little more each time it is used, and it leaves a smell that clings to the kitchen. Our solution floats the baked carbon off the metal without attacking it, which is the whole reason you can switch the oven on and cook the same evening.

One exception, and it is an important one. Catalytic and self-cleaning liner panels, the rough ones in the back and sides of some ovens, must never be scrubbed or dipped, or the coating that does the self-cleaning is wrecked. We leave them be and work around them. A quick word at the door about what your oven has saves a ruined panel and a sour mood all round.
Affinity Water, hard water and oven glass
Windsor sits on chalk, and the supply Affinity Water draws here is hard, usually somewhere between 250 and 350 parts per million of calcium carbonate. You see it on the kettle and the shower screen, and you see it on the inside of the oven door, where a white haze settles under the grease and a normal clean walks straight past it.
We take that limescale film off the door glass on every single oven we do, which is exactly why the glass comes up clearer than any weekend scrub at home leaves it. It is also why the steam-clean cycle on newer ovens never quite gets there in this town. The mineral load is simply too high. The steam loosens the surface grease and stops, and people ring us anyway once they have run the cycle twice and seen no real change.
Hard water is the local quirk that costs a Windsor oven the most. We deal with it as a matter of course.

Hobs, extractors, microwaves, ranges and AGAs
People nearly always book the oven first, then add the hob the moment they notice it looks far worse sat next to a clean oven than it did five minutes earlier. Gas hobs take longer than ceramic. The burner caps, the crowns and the cast trivets all lift off into the tank and go back on clean and seated properly, so the flame burns even again instead of leaning to one side.
The extractor is the part almost everyone forgets, and a grease filter over a hob in daily use turns into a solid sticky mat that is a real fire risk as much as a smell. We degrease the metal mesh filters and wipe the canopy down. Carbon filters in recirculating hoods are usually a replace-not-clean part, so we check yours and tell you honestly whether it is worth keeping. If your hood ducts out through the wall, that is one less worry.
The microwave at £22 is the quiet bargain. Out comes the turntable and the roller ring, and we get at the splatter baked onto the inside roof that the daily wipe never reaches.
Ranges and AGAs deserve a line of their own, because Windsor has more of both than a town this size has any right to. A 90cm range cooker has two cavities, a wider grill and a great deal more glass, which is why it is £114 rather than the £110 a standard double costs. An AGA is its own beast, worked cool, handled gently round the enamel and the chrome lids, and charged at £143 for the usual two-oven model. The larger Victorian and Edwardian houses in the Golden Triangle, and the family homes backing onto the Great Park, throw up plenty of both.
Windsor kitchens, from the Golden Triangle to the riverside flats
Windsor is two kinds of kitchen sharing one town. There is a lot of period stock, and there is a steady run of newer flats near the river and the two stations.
The Golden Triangle, the wedge of streets near the centre between the two railway stations, is mostly Georgian, Victorian and Edwardian, and the kitchens there have usually been knocked through to the back with a freestanding range or a big double oven dropped in. The Victorian terraces along Oxford Road run the same way. Out at Clewer and Dedworth you get more interwar and post-war semis with fitted double ovens, and Spital sits somewhere between the two. The bigger detached houses edging the Great Park keep a range cooker or an AGA more often than not.
Then there are the flats. The blocks down by the Brocas and along the river near Windsor and Eton Riverside, and the newer schemes that have gone up around the town, mostly come with a compact single oven and an induction hob. Those are quick for us and cheap for you, so in a single week we end up cleaning a tired AGA in a Triangle townhouse on the Monday and a year-old single oven in a riverside flat on the Tuesday.
If you are moving out rather than just keeping on top of the place, the oven is the item the inventory clerk checks last and fails you on first. We can fold it into a full end of tenancy cleaning in Windsor visit, or pair it with carpet cleaning in Windsor on the same trip, so the van only has to find a space on your road the once.
Parking, permits and the day itself
Parking near the centre needs a bit of thought, because the Royal Borough of Windsor and Maidenhead runs resident permit zones across a lot of the streets close to town, St Leonards Road among them, and the council uses the MiPermit app for visitor sessions rather than paper scratchcards. The van has to sit within a sensible carry of your door, since the tank kit is heavy, so if you are in a permit street or one of the riverside flats, ring 0333 555 2076 when you book and we will get a visitor session sorted or use a nearby car park. Out at Dedworth, Clewer and Old Windsor it is rarely a problem.
On the day, all we ask is that you clear the worktop beside the oven. We put protection down, take the oven apart, run the tank, rebuild it and test the door seal before we go. A single oven is generally about ninety minutes. A range or an AGA wants longer. You can read more on our oven cleaning service page, and if you want the whole place kept on top of through the year, we also do domestic cleaning in Windsor.

Payment is on completion, once you have looked the oven over and you are happy. Card or bank transfer, whichever suits, and a proper invoice by email rather than a scrap of paper.
Then we are gone.
Who we are, and the re-clean guarantee
We are Monster Cleaning Ltd, Companies House number 9919639, cleaning since 2014. The office is at 255 Upper Richmond Road West, SW14 8QS, and we run a regular oven round west out of London through Berkshire and into the SL4 postcodes around Windsor.
I will be straight about the reviews, because you will find them with or without me pointing them out. Our Trustpilot sits at 3.1 out of 5 across 128 reviews. That is not a number I am going to polish up. Most of the lower scores are about scheduling on the regular domestic side rather than the oven work, and tightening that up is exactly why we changed how we book and confirm jobs. Oven cleaning is where we are at our sharpest, and the guarantee is there to back that up.
The guarantee is plain. If the oven is not right when we finish, say so to the cleaner before they leave or ring the office that same day, and we come back and re-do it for nothing. Same-day re-clean, no arguing the toss. We would much rather sort it on the spot than read about it in a one-star review a week later.
Frequently asked questions
How much is oven cleaning in Windsor?
A single oven is £77, a double oven is £110, a 90cm range cooker is £114 and a two-oven AGA is £143. A hob is £23 to £28, an extractor is £28 and a microwave is £22. Those are the flat prices we charge across the SL4 postcodes, with nothing added at the door.
Can I cook in the oven the same day you clean it?
Yes. We clean with a non-caustic dip-tank, so there is no harsh residue and no chemical smell left behind. Switch it on and cook your tea the same evening, with no need to leave a window open overnight.
Do you use caustic oven cleaner?
No. The heated tank in our van runs a non-caustic solution. It lifts the baked-on carbon off the racks and panels without eating into the aluminium trim or dulling the enamel, which is what the old caustic-soda dips do over the years.
How long does an oven clean take in Windsor?
A single oven is usually about ninety minutes. A double takes a bit longer, and a range cooker or an AGA can run to a couple of hours, because there are more cavities, more glass and more parts to lift out, soak and refit.
Do you clean AGAs and range cookers?
Yes. A 90cm range cooker is £114 and a standard two-oven AGA is £143. We work an AGA cool and go gently round the vitreous enamel and the chrome lids. Both turn up often in the bigger period houses in the Golden Triangle and out towards the Great Park.

Will the hard water marks come off the oven door glass?
Mostly, yes. Windsor is on Affinity Water, which runs hard here at roughly 250 to 350 parts per million of calcium carbonate, so the inner door glass scales up with a white haze. We take that film off as part of every clean, so the glass ends up clearer than a wipe at home ever leaves it.
Can you do the hob and the extractor at the same time?
Yes, and most people do once they see the oven clean next to a greasy hob. A hob is £23 to £28 depending on whether it is a flat ceramic top or a gas hob with trivets and burner caps that all come apart. An extractor is £28, which covers degreasing the metal mesh filters.
What about catalytic or self-cleaning liners?
We leave those alone. The rough liner panels in the back and sides of some ovens are ruined if you scrub or dip them, so tell us before we start and we clean the cavity and the glass around them by hand instead.
Which areas around Windsor do you cover?
We cover Windsor town and the SL4 postcodes, including Clewer, Dedworth, Spital, the Golden Triangle streets near the centre, and out to Old Windsor and Datchet. If you are not sure your road is on the round, ring the office and we will tell you straight.
Do you clean ovens in the new riverside flats?
Yes. The flats around the Brocas and the older riverside blocks near Windsor and Eton Riverside tend to have a single oven and an induction hob, which is a quick job for us and a cheaper one for you. Parking near the river is the only thing worth sorting in advance.
What if I am not happy with the oven once you have finished?
Tell the cleaner before they leave, or ring the office the same day, and we come back and re-do it for free. That is our same-day re-clean guarantee, and it covers every oven we touch. We would far rather put it right there and then.
How do I book and how do I pay?
Ring 0333 555 2076 or email [email protected] with your postcode and what you want cleaning. You get a flat price and a two-hour arrival window. You pay once the work is done and you have looked the oven over, by card or bank transfer, with a proper invoice by email.
