Green paving, moss-filled joints and stubborn patches of discolouration can completely change how a patio looks. What was once an attractive outdoor space can gradually become hidden beneath layers of organic growth, leaving the original colour of the stone barely visible.
At The Patio Black Spot Removal Company, we specialise in professional patio cleaning and pressure washing in Portsmouth, helping homeowners remove the organic staining responsible for most patio discolouration. Based on our experience, approximately 99.9% of the staining we encounter is organic, ranging from algae and lichen to moss, decomposing leaves and soil deposits.
Having cleaned over 1,000 patios annually, we've worked with everything from reclaimed York stone and natural limestone to porcelain, sandstone and concrete paving flags. Our experience allows us to clean a wide variety of surfaces using specialist treatments developed to tackle unwanted growth and bring out the paving's natural appearance.
Whether your paving has become covered in green growth or developed years of accumulated staining, our team can help restore its appearance.

Not every patio becomes discoloured in the same way. Some develop a widespread green covering, while others have concentrated patches of moss, lichen or marks left behind by garden debris.
Our specialist treatments address the organic material responsible for these changes, including:
A patio may be affected by several of these problems at once, particularly when organic deposits have accumulated over an extended period.
Our cleaning service addresses the wider condition of the paving rather than concentrating on individual black spots. Removing suitable organic staining can reveal colours and surface details that have been hidden beneath the build-up.
This can make a noticeable difference to patios, suitable pathways and other paved outdoor areas.
A professional Deep Clean removes existing organic staining, but outdoor paving will continue to be exposed to the elements afterwards.
To help customers maintain their patios, we offer two follow-up services with different levels of cleaning.
Some homeowners prefer to have their patio professionally cleaned each year, rather than allowing organic deposits to accumulate again.
Our Annual Patio Clean repeats the specialist treatment used during the original service, followed by light pressure washing.
This addresses new organic staining and refreshes the appearance of the paving. Customers who arrange the service annually benefit from a reduced price.
Where the previous Deep Clean has left the patio in good condition, a further pressure wash may not be necessary.
Our Spray and Leave Maintenance Treatment uses Patio Black Spot Preventer, which helps stop new lichen spots developing and removes green algae within a few days.
The product is applied without pressure washing, making it an alternative to a full annual clean.
We recommend the first application approximately 11 months after the original Deep Clean, followed by yearly treatments.
You can book our team to carry out the application or purchase Preventer separately and apply it yourself in accordance with the product instructions.
You can obtain a quotation by sending us photographs of the paving you'd like cleaned.
There's no need to work out the measurements beforehand. We calculate our prices according to the size of the job and the location of your property.
Photographs taken from a distance are particularly helpful because they show the full extent of the paved area. Try to capture the entire patio rather than concentrating exclusively on the sections with the heaviest staining.
Please include your address and a contact telephone number.
Send your photographs using either option:

The surface beneath the staining is just as important as the organic growth covering it. A cleaning approach suitable for one material may not be appropriate for another, particularly where natural stone and manufactured paving have different characteristics.
Our team has experience working with a broad selection of materials:
We don't expect customers to know exactly which paving material they have before making an enquiry.
Our experience allows us to consider the characteristics of the surface and select a cleaning product suited to the work.
When organic growth has accumulated across a patio, ordinary pressure washing may remove loose dirt without fully addressing the deposits responsible for its discoloured appearance.
Our Professional Patio Deep Clean is designed to provide a more comprehensive treatment.
We use specialist patio cleaning products developed by our company, with formulations selected according to the paving material.
The cleaning treatment is applied to tackle algae, moss, lichen and other suitable organic deposits. After the product has been allowed to work, we complete the process using light pressure washing.
This approach places the emphasis on the cleaning treatment rather than using excessive water pressure, which can damage some paving materials or disturb pointing.
Our products are biodegradable and acid free, and the area is left pet friendly once the work has been completed.
The objective is to remove organic staining and bring out more of the paving's natural colour, with the final appearance depending on the surface and its existing condition.
Professional patio cleaning involves understanding both the material being treated and the type of organic staining affecting it.
Through cleaning more than 1,000 patios every year, we've gained extensive experience working with different paving surfaces, from older natural stone to modern manufactured slabs.
We've also developed our own specialist cleaning products to address common organic staining, allowing us to offer a considered approach rather than relying solely on conventional jet washing.
You don't need to select a cleaning product, identify the cause of every mark or decide which maintenance service is appropriate before contacting us.
Tell us about your patio and we'll explain the available options, whether you need a comprehensive Deep Clean, a repeat Annual Clean or a preventative Spray and Leave Treatment.
Our aim is to help Portsmouth homeowners achieve cleaner, more attractive outdoor paving through professional treatment, with straightforward maintenance options available afterwards.
