HEPA extraction, enzyme treatments, and eco-friendly products to reduce allergens and eliminate pet odours from carpets and upholstery.
Particle Capture Rate
Our HEPA vacuums capture 99.97% of particles — dust mites, pet dander, pollen — before the wet clean.
We break down uric acid crystals — the source of pet odour — not just mask them with fragrance.
No harsh chemicals or heavy fragrances. Our products are non-toxic once dry.
Southampton’s coastal climate makes this worse. The maritime air brings higher humidity, and damp conditions encourage dust mites and mould growth in soft furnishings. Pollen levels spike sharply in spring and early summer as windows are opened to the sea breeze. For allergy sufferers, this combination of indoor allergens and outdoor triggers can be especially difficult to manage.
Dust mites: Microscopic creatures that live in bedding, carpets, and upholstery. They feed on shed human skin cells and thrive in warm, humid environments. Their waste particles are a major trigger for asthma and allergic rhinitis. A single gram of carpet dust can contain thousands of dust mites.
Pet dander: Tiny flakes of skin shed by cats, dogs, and other animals. Unlike pet hair, dander is microscopic and airborne, settling deep into carpet and upholstery fibres. Even homes where pets no longer live can retain dander for months or years.
Pollen: Tracked in on shoes and clothing, or carried on the breeze through open windows. Pollen accumulates in carpet pile and is stirred up with foot traffic. In Southampton, grass and tree pollen seasons are particularly pronounced.
Mould spores: In Southampton’s damper months, moisture in carpets and upholstery — whether from spills, condensation, or simply humid air — creates conditions for mould growth. Mould spores are potent allergens and can cause respiratory symptoms.
Bacteria: Carpets and upholstery accumulate bacteria from shoes, pets, skin contact, and food debris. While not allergens in the traditional sense, some bacteria contribute to odours and can irritate sensitive airways.
Regular household vacuuming removes surface debris but is not effective at extracting the fine particles that trigger allergies. Standard vacuum cleaners also expel fine particles back into the air during use. Professional cleaning addresses allergens at a different level entirely.
HEPA vacuuming: We use professional HEPA-filtered vacuums during our pre-cleaning phase. HEPA filters capture 99.97% of particles down to 0.3 microns in size — that includes dust mite waste, pet dander, and pollen. Unlike standard domestic vacuums, they don’t recirculate fine particles back into the air.
Hot water extraction: Our hot water extraction process reaches deep into carpet pile and upholstery fibres, where allergens accumulate beyond the reach of surface cleaning. The hot water and extraction process physically removes allergen-laden particles from the fabric.
Specialist allergen treatments: On request, we can apply anti-allergen treatments that help denature (neutralise) dust mite allergens. These treatments don’t kill dust mites but render their waste particles less reactive — useful between professional cleans.
Pet odours in carpets and upholstery are one of the most persistent problems we deal with. The difficulty is that pet urine doesn’t just affect the surface — it soaks through carpet pile into the backing material and, in severe cases, into the underlay beneath. Standard cleaning removes the visible stain but leaves odour-causing compounds in the deeper layers.
Pet urine contains uric acid, which forms crystals as it dries. These crystals bind tightly to fibres and are not broken down by water-based cleaning alone. In humid conditions — common in Southampton — uric acid crystals can temporarily reactivate, releasing odour even after surface cleaning.
Localisation: We identify all affected areas, including spots not visible to the naked eye. Pet accidents often extend beyond the visible stain.
Enzyme pre-treatment: We apply specialist enzyme-based solutions designed specifically for pet urine. Enzymes break down uric acid crystals and the organic compounds responsible for odour at a molecular level. This is fundamentally different from odour masking — we eliminate the source rather than covering it with fragrance.
Dwell time: Enzyme treatments need time to work. We allow adequate dwell time before proceeding to the extraction stage.
Hot water extraction: Deep extraction removes the treated residue, the broken-down compounds, and the cleaning solution from the carpet or upholstery.
Assessment: For severe or long-standing pet contamination that has penetrated into the underlay, we’ll advise honestly. In some cases, underlay replacement is necessary for complete odour removal. We don’t charge for extraction and then tell you the problem remains — we assess before we start.
For households with allergy sufferers, asthma, or pets, we recommend professional carpet and upholstery cleaning every 6 to 12 months rather than the standard 12 to 24 months. Regular professional cleaning forms part of an effective allergen management strategy alongside other measures such as allergen-proof mattress covers, regular washing of bedding, and HEPA-filtered domestic vacuuming between professional cleans.
We use eco-friendly, low-residue cleaning solutions that are safe for children and pets once the treated surfaces are dry. We avoid heavily fragranced products — synthetic fragrances can themselves be irritants for people with sensitivities. Our focus is on thorough removal of allergens and contaminants, not masking them with scent.
Many allergy sufferers notice an improvement relatively quickly after professional cleaning — reduced irritation, fewer symptoms at home, and generally fresher air in the property. We can’t make medical claims, and results vary by individual and the overall allergen load in the property. But the reduction in particulate matter in carpets and upholstery following professional cleaning is well documented.
For pet odour: most odours are significantly reduced immediately after treatment. In some cases, a faint residual odour may remain for a short period as deep fibres complete the drying process — this typically resolves as the carpet dries fully.
We provide allergy and pet odour treatment across Southampton including Shirley, Bitterne, Portswood, Highfield, Bassett, Ocean Village, Eastleigh, Totton, Hedge End, and Chandlers Ford.
Can professional carpet cleaning help with my hay fever?
It can reduce the pollen load in your carpets and upholstery, which is one contributing factor. It won’t prevent outdoor exposure, but reducing indoor allergens can make symptoms more manageable during high-pollen periods.
Is professional cleaning safe for asthma sufferers?
Yes. Our cleaning solutions are low in VOCs and residue-free. We recommend asthma sufferers leave the property during cleaning and return once surfaces are dry. We’ll advise you on timing.
My previous carpet was cleaned but the pet smell came back. Why?
This is almost always because the contamination had reached the underlay or carpet backing, which surface cleaning cannot reach. Our enzyme treatments and deep extraction go further than surface cleaning. In severe cases, underlay replacement may be the only complete solution.
Will cleaning remove all pet dander?
Professional cleaning significantly reduces pet dander levels. Complete elimination is not possible — particularly if pets are still present in the home — but regular professional cleaning keeps levels substantially lower than household vacuuming alone.
Are your products safe for my cat or dog?
Yes. Our products are non-toxic and safe for pets once surfaces are fully dry. We recommend keeping pets off cleaned areas until dry, typically 4 to 8 hours.
How long does allergy treatment take?
Treatment time depends on the size of the property and the number of areas affected. A typical 3-bedroom home takes 3 to 4 hours. We’ll confirm timing when you book.
We identify all affected areas, including pet accident zones not visible to the naked eye.
We vacuum with HEPA-filtered equipment to remove dry allergen particles before wet cleaning.
Enzyme treatment is applied and allowed to dwell — breaking down odour at a molecular level.
Hot water extraction removes treated residue, allergens, and cleaning solution from the fibres.
