Mould Treatment in Streatham SW16

Mould is a persistent problem in many properties, particularly in bathrooms, kitchens and bedrooms with limited ventilation. I treat mould in homes and rental properties across Streatham SW16 and the surrounding areas. That includes cleaning and treating the affected surfaces, removing mouldy silicone, anti-mould resealing, stain blocking, anti-mould paint, and practical advice on ventilation and condensation.

Qualifying mould-treatment work may include a written 6–12 month workmanship warranty, depending on the agreed treatment scope and property conditions. Exact terms are confirmed in the quotation.

Before & After Mould Treatment

Examples of mould treatment, anti-mould resealing and surface preparation work. Every property is different, but these photos show the type of finish that can usually be achieved when the affected area is properly cleaned, treated and resealed. See more before-and-after photos in my gallery.

Professional Mould Treatment for Homes & Rental Properties

Mould should not simply be wiped away or painted over. If the affected surface is not cleaned and treated correctly first, staining and mould growth can return quickly.

A proper mould treatment usually involves cleaning the affected area, applying suitable anti-mould treatment, removing contaminated silicone where needed, resealing with mould-resistant sanitary silicone, and preparing the surface for stain blocking or anti-mould paint where required.

It's for landlords, homeowners and letting agents who want the job done properly, not just covered up.

Common Mould Problem Areas

Mould can appear in different parts of a property depending on ventilation, heating, insulation and how the room is used. The most common areas I deal with are bathrooms, kitchens, bedrooms, window reveals, ceilings and silicone joints around baths, showers and sinks.

Bathroom Mould

Treatment for mould on ceilings, walls, grout lines and silicone around baths, showers and basins. Mouldy silicone can be removed and replaced with anti-mould sanitary silicone where needed.

Bedroom & Window Mould

Treatment for mould around windows, external walls, corners and wardrobes where condensation or cold surfaces are causing staining and growth.

Kitchen Mould

Treatment for mould around sinks, windows, ceilings and poorly ventilated areas. Suitable for occupied homes and rental property refreshes.

Rental Property Mould

Mould treatment for landlords and letting agents before viewings, inspections, new tenancies or after a tenant reports a problem.

Mould Treatment for Landlords & Letting Agents

Mould is one of the most common issues in rental properties, especially in bathrooms, bedrooms, kitchens and around windows. I work with landlords and letting agents who need mould treated quickly and properly before a viewing, inspection, new tenancy or end-of-tenancy handover.

I can attend rental properties across Streatham and South London, provide photo updates, communicate clearly with tenants or agents, and issue itemised invoices for your records. See a Croydon CR0 landlord mould-treatment case study and a Streatham SW16 between-tenancy refresh that included mould treatment. In Norbury SW16, I traced damp walls to a leaking toilet pipe, fixed it, dried the walls and finished with Zinsser Perma-White anti-mould paint — see my Norbury SW16 case study.

Here are the questions people ask me most about mould.

Mould Treatment FAQs

Q. Can you remove black mould?

A. Yes. I treat visible black mould on walls, ceilings, bathrooms, kitchens, bedrooms, silicone joints and around windows. Where silicone is badly affected, it can be removed and replaced with anti-mould sanitary silicone.

Q. Do you just paint over mould?

A. No. Mould should be cleaned and treated before any painting is done. Painting directly over mould usually fails because staining or growth can come back through the paint.

Q. Can you replace mouldy silicone around a bath or shower?

A. Yes. Mouldy silicone around baths, showers, sinks and basins can be removed and replaced with fresh mould-resistant sanitary silicone. This is often the best option when mould has gone deep into the old sealant.

Q. Do you offer a warranty on mould treatment?

A. Qualifying mould-treatment work may include a written 6–12 month workmanship warranty, depending on the agreed treatment scope and property conditions. Exact terms are confirmed in the quotation. The warranty does not cover mould returning because of ongoing condensation, damp, leaks, poor heating or blocked ventilation.

Q. Can you treat mould in a rental property?

A. Yes. I regularly help landlords and letting agents with mould treatment in rental properties, especially before viewings, inspections, end-of-tenancy handovers and new tenant move-ins. I send photo updates.

Q. Will mould come back after treatment?

A. Mould can return if the underlying cause is still present. Common causes include condensation, poor ventilation, cold walls, leaks, damp, blocked extractors or drying clothes indoors. I treat the visible mould properly and give practical advice to reduce the chance of it returning.

Q. Do you treat bathroom mould?

A. Yes. Bathroom mould is one of the most common jobs I deal with. Treatment can include cleaning, anti-mould treatment, removing mouldy silicone, resealing around baths and showers, stain blocking and anti-mould paint where needed.

Q. Can you treat mould around windows?

A. Yes. Mould around windows is usually linked to condensation, cold surfaces or poor airflow. I can treat the affected area and advise on practical steps to reduce future condensation and mould growth.

Q. What photos should I send for a mould treatment quote?

A. Send clear photos of the affected area, the whole room, any extractor fan or window nearby, and close-up photos of silicone, walls or ceilings where mould is visible. This helps me advise what treatment is likely to be needed.

Q. How much does mould treatment cost?

A. It depends on how big the affected area is and what's causing the mould. Mould behind units or appliances is quoted individually, and an extractor-fan replacement with mould treatment is quoted as one package. Send me photos on WhatsApp and I'll quote.

Q. Can you replace an extractor fan as part of mould treatment?

A. Yes. Extractor-fan replacement can be combined with mould treatment and quoted as one package. See my Croydon CR0 case study.

Q. Do you treat mould in Croydon, Norbury and Tooting?

A. Yes. I'm based in Streatham SW16 and treat mould across Streatham, Norbury, Croydon, Tooting, Balham and surrounding South London areas.

Q. Do you use anti-mould paint?

A. Yes, where suitable, after fungicidal treatment and stain blocking. See my Norbury SW16 case study.
