If someone in your home sneezes through the mornings or wakes up stuffy, you've probably wondered whether a professional carpet clean would actually help. Our honest answer: it can genuinely reduce what builds up in your carpets and mattress — but it isn't a medical treatment, and no cleaner should tell you otherwise. Here's what's really in the pile, what hot-water extraction does about it, and the routine that makes the biggest difference.
What's actually in your carpet
Carpets act like a filter for the room. Dust, pollen walked in on shoes, pet dander and everyday skin flakes all settle into the pile and stay there, rather than floating about in the air. That's helpful — but only if the filter gets emptied now and again.
Then there are dust mites. They're tiny creatures that live in soft furnishings — carpets, mattresses, sofas — and feed on the skin flakes we all shed every day. You'll never see them, and they don't bite. For many people it's mainly their droppings, rather than the mites themselves, that trigger the sneezing, itchy eyes and stuffy noses.
A normal vacuum lifts the surface layer, which is well worth doing. But over months and years the finer debris works its way deep into the pile, below where a household vacuum can reach. That deep build-up is the reservoir — and the bigger it gets, the more gets stirred back into the air every time someone walks across the room.
What a professional clean actually does
Our carpet cleaning uses professional hot-water extraction — often called steam cleaning — with Prochem machines and solutions. Hot water and cleaning solution are driven deep into the pile, then immediately extracted back out, taking the loosened soiling with them. It's a physical flush-through of the carpet, not a spray-and-hope treatment: the dust, dander and much of the mite debris that's built up in the pile comes out with the water.
That's the honest strength of the method: it doesn't mask what's in the carpet, it removes a good deal of it. The same goes for rugs and sofas and upholstery, which collect the same mix.
What it won't do — the honest bit
- It won't cure an allergy or asthma. If symptoms are troubling you, that's a conversation for your GP, not your carpet cleaner.
- It won't remove every mite, and it won't keep them away forever — they live wherever people do, and the build-up returns gradually. That's why cleaning is part of an ongoing routine, not a one-off fix.
- It won't help much on its own. A deep clean empties the reservoir; the everyday habits below keep it low between cleans.
Don't forget the bed — it matters just as much
Carpets get the attention, but the mattress is a dust mite's favourite address: warm, slightly humid, and topped up nightly with the skin flakes they feed on. You spend seven or eight hours a night with your face inches from it.
Our mattress cleaning uses the same hot-water extraction approach to flush that build-up out — fixed prices from £15 for a single up to £30 for a super king. If you're having bedrooms done anyway, it makes sense to do the mattress on the same visit.
- Vacuum slowly, once or twice a week — a vacuum with a HEPA filter holds onto the fine dust rather than blowing it back out.
- Wash bedding regularly on a hot wash — bedding is the easiest soft furnishing to keep genuinely clean.
- Air the rooms daily — dust mites thrive in warm, humid rooms, so a few minutes with the windows open helps.
- Keep pets off beds and sofas if dander is one of your triggers.
- Book a periodic deep clean of carpets, mattress and sofa to empty out what the vacuum can't reach.
Is the cleaning itself sensible for a sensitive household?
We're often asked this. We use professional Prochem products exactly as directed, and hot-water extraction finishes with a thorough rinse, so we're not leaving a soup of chemicals in your carpet. Afterwards, keep children and pets off until it's dry and let the room air — carpets are usually touch-dry within a few hours and fully dry in around 4 to 6 hours, depending on the room and ventilation. On delicate fibres we always test a hidden patch first.
What it costs
Our prices are fixed, with no VAT added and no hidden extras: bedrooms and living rooms are from £20 each by size (£40 for a through-lounge), mattresses £15 to £30, and upholstery from £20 per seat. Book two rooms and the third (cheapest) room is free — when you book online (one per booking). You'll find the full list on our carpet cleaning prices page — and if you're wondering about frequency, our guide on how often carpets need cleaning suggests every 3 to 6 months for allergy households.
Allergy questions we're often asked
Does carpet cleaning kill dust mites?
We'd rather not make kill-rate claims — what hot-water extraction reliably does is physically flush much of the dust, dander and mite debris out of the pile. Mites do return over time, which is why regular cleaning works better than a single deep clean.
How often should carpets be cleaned if someone has allergies?
For allergy or asthma households, every 3 to 6 months is a sensible rhythm for the busiest rooms, with quieter rooms less often. Quiet, pet-free homes can usually stretch much longer.
Will it get rid of my symptoms?
Honestly — we can't promise that, and you should be wary of anyone who does. Cleaning reduces the allergen build-up held in carpets, mattresses and sofas; managing the allergy itself is one for your GP.
Should I have the mattress done at the same time?
If allergies are the reason you're booking, yes — the bed is where dust mites are happiest, and doing it alongside the bedroom carpet saves a second visit. One honest note: stain removal on mattresses can never be guaranteed, and we'll always tell you up front what we expect to achieve.
Is it safe for babies and pets?
We use professional products as directed and rinse thoroughly with hot-water extraction. Just keep little ones and pets off the carpet until it's dry — usually a few hours — and let the room air.
We're a family-run Watford firm, trading since 2014, fully insured and DBS-checked — and we'll always tell you straight what a clean will and won't achieve. Fixed prices, no VAT added, and we usually reply within 15 minutes.
