Understanding Our Mould Removal Pricing
Let’s talk about what really matters – the cost. You’re here because you want to know if solving your mould problem is going to cost the equivalent of a weekend getaway or a significant renovation investment.
Just last Thursday, our specialists were consulting with a couple in Hammersmith who’d received quotes ranging from £200 to £2,400 for what appeared to be identical work. The husband looked at our team member, visibly frustrated, and said, “We just want someone to be straight with us.” We completely understood their position.
At Mould Removal Specialists, we’ve built our entire pricing approach on transparency. Could we employ the strategy where we quote low to secure the job, then “discover” additional problems once we’re in your home? Certainly, but that’s not how we operate. We prefer to tell you what things actually cost from the beginning.
Why Mould Removal Costs Vary Significantly
- Extent and depth: Surface mould that’s just beginning to appear requires different treatment than established growth that has penetrated deeper into structural materials
- Accessibility challenges: Mould behind fixed kitchen units presents considerably more complexity than visible growth on a bathroom ceiling
- Treatment complexity: Some situations require only specialized anti-mould treatments, while others necessitate removing materials and rebuilding affected sections
- Root cause factors: Addressing simple condensation issues costs substantially less than remedying long-term structural dampness
Our Mould Removal Price List
To be entirely transparent, offering a single price for all mould situations would be misleading. Each mould problem presents unique characteristics and challenges. The following prices provide a reliable starting point, though your specific circumstances may adjust the final cost.
Worth noting: While these rates cover approximately 90% of situations we encounter (based on the 2,300+ London properties we treated last year), the most accurate assessment comes after a professional evaluation of your specific issue. The approach for a period Victorian conversion in Brixton often requires different techniques than those effective in a modern new-build in Canary Wharf.

These examples represent common scenarios we encounter. Your situation may present different challenges—each property develops its own distinct mould profile. In a recent project behind a kitchen in Hackney, what initially appeared to be a standard treatment revealed extensive damage to the underlying floorboards once we began our work, requiring a more comprehensive approach.
For an accurate, fixed-price quote without unexpected adjustments later, booking an inspection is the most effective approach. It saves time, prevents complications, and potentially reduces overall costs.
Common Questions About Mould Removal Prices
Do I get the inspection fee back if I hire you for the treatment?
Yes, absolutely. If you proceed with our recommended treatment within 30 days, we deduct the inspection fee from your final invoice. This approach ensures fairness—we receive compensation for our professional assessment, while clients aren’t effectively paying twice when choosing us for the remediation work.
What if the mould returns after you’ve treated it?
All our treatments include a 6-month guarantee. If mould reappears within this period (provided you’ve followed our aftercare recommendations), we’ll return and retreat the affected areas at no additional cost.
It’s important to note that this assumes the underlying cause has been addressed. If there’s an unresolved moisture source such as an active leak, we unfortunately cannot guarantee against new mould formation resulting from continuing water ingress.
I’ve seen companies advertising mould removal for £99 – why are your services priced differently?
We recently worked with a client in Fulham who had previously used one of these advertised specials—the initial £99 quote increased to £600 once on site, with additional charges for “severe mould” (which was actually quite standard) and “difficult access” (in a conventional bathroom setup).
The mould subsequently returned within two months of treatment.
Professional mould remediation requires specialized products, equipment, and expertise that cannot be delivered at extremely low price points. Many budget services apply bleach-based solutions that remove surface discoloration but fail to address the hyphae (root structures) growing within materials. This fundamental limitation explains why such treatments typically show poor longevity, particularly during humid periods.
Will I need to move my furniture before you arrive?
Our pricing includes reasonable furniture moving. However, if you can relocate smaller items away from affected walls before our arrival, it enhances efficiency. For particularly heavy items such as pianos or substantial wardrobes, we may need to discuss additional assistance or supplementary charges—but we’ll always address this during the inspection rather than introducing it unexpectedly on the day of treatment.
How quickly can you begin work once I’ve approved the quote?
Typically within 2-7 days of quote acceptance. During peak periods (often following extended rainy periods when mould problems become more prevalent across London), wait times may extend to 10-14 days.
For urgent situations, we offer priority scheduling at a premium rate, which can facilitate service within 24-48 hours in most circumstances. We recently provided emergency response to a childcare facility in Streatham after they discovered significant mould in a children’s rest area—situations like these require immediate attention.
Does your pricing include VAT?
Yes, all listed prices include VAT. The quoted amount is exactly what you’ll pay—no hidden costs or unexpected additions when invoiced. Your invoice will clearly itemize the VAT component for business clients who need to reclaim it.
My landlord should cover this expense – can you invoice them directly?
Absolutely. Many mould issues in rental properties are the landlord’s responsibility, particularly when caused by structural deficiencies or inadequate ventilation. We’re happy to invoice landlords or property management companies directly.
Many tenants find our detailed inspection reports valuable in securing appropriate action from landlords—our comprehensive analysis of causes often helps overcome dismissive responses. Our specialists have provided expert testimony in several housing tribunals this year for tenants facing unresolved mould issues.
Can I receive a discount for multiple room treatments?
Yes, we offer 10% off the second room and 15% off the third room onwards when booked together. This structure benefits both parties—our team and equipment are already on-site, and clients receive more cost-effective comprehensive treatment.
What’s the most cost-effective approach to resolving my mould problem?
From our extensive experience, the most economical approach is addressing the issue properly the first time. After 11 years specializing in London’s unique moisture challenges, we’ve observed many clients invest repeatedly in DIY solutions or budget treatments, ultimately requiring our services when the mould inevitably returns.
For those with genuine budget constraints, we recommend booking an inspection (£65-105), which allows us to provide tailored advice on potential interim measures that might effectively manage your specific situation until comprehensive treatment becomes feasible.
