Has your patio gradually become a patchwork of green, grey and dark marks, leaving little of its original colour visible? What might appear to be ageing paving is often the result of organic material collecting and growing across the surface. With the right treatment, much of this discolouration can be removed without replacing the slabs.
At The Patio Black Spot Removal Company, we offer professional pressure washing services in Gosport, specialising in comprehensive patio cleaning for homeowners who want to improve the appearance of their outdoor spaces.
We clean over 1,000 patios every year, treating everything from traditional natural stone to contemporary porcelain and concrete paving. Based on our experience, approximately 99.9% of patio staining is organic, with common causes including algae, moss, lichen, fallen leaves and soil residue.
Our specialist cleaning products are developed to tackle these deposits and bring out the underlying colour of sandstone, limestone, reclaimed York stone, Travertine and other paving materials. The emphasis is on treating the staining itself, rather than simply using more powerful water pressure.
If your patio has lost its original appearance beneath accumulated organic growth, our team can help you understand what professional cleaning could achieve.

Outdoor paving is exposed to more than rain and everyday dirt. Organic material from the garden can settle, grow or break down on the surface, leaving different forms of discolouration.
Our cleaning treatments address a broad range of these problems.
Green algae and surface growth
Algae can spread across paving and create a green covering that makes the material underneath difficult to see. It is commonly associated with areas where moisture persists.
Moss around slabs and joints
Moss can develop in the spaces between paving, along edges and across suitable damp surfaces. Its growth can make a patio appear overgrown even when the surrounding garden is maintained.
Black and white lichen spots
Lichen can become firmly attached to natural stone and manufactured paving. These spots may remain visible after ordinary pressure washing and benefit from specialist treatment.
Staining from fallen leaves
Leaves left on the patio can break down and leave organic marks behind. Removing the loose leaves doesn't necessarily remove the staining they've caused.
Soil and residue from garden containers
Compost, soil and organic material washed from pots can create patches of discolouration, particularly around planted areas.
Accumulated green deposits
A mixture of organic growth and garden debris can gradually cover the paving, concealing its original finish and colour.
Our comprehensive cleaning service is designed to address suitable organic staining across the surface, not simply individual black spots.
Removing these deposits can improve the appearance of garden patios, paved seating areas, paths and other suitable outdoor surfaces.
Once the initial Deep Clean has addressed the accumulated staining, you can decide how you'd prefer to maintain the paving in the following years.
We offer two different annual services.
Our Annual Patio Clean is intended for homeowners who want their patio to receive another thorough professional clean each year.
We repeat the specialist cleaning treatment to remove suitable organic deposits that have developed since the previous visit. A light pressure wash completes the process.
The service is available at a reduced price for annual customers, providing an option for maintaining the appearance of the paving.
If your patio remains in good condition following its original Deep Clean, another 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.
No pressure washing is involved.
The first application is recommended approximately 11 months after the original Deep Clean, followed by annual treatments.
Customers can arrange professional application or purchase the product separately and follow the instructions for DIY maintenance.
You can obtain a quotation by sending photographs of your patio, without needing to measure the paving yourself.
Our prices depend on the size of the area requiring treatment and your property's location.
Take a few photographs from a distance that show the entire patio. Wider images allow us to estimate the area more accurately than close-up photographs of individual marks.
Please include your property address and telephone number.
Send your photographs through either method:
If you haven't received a response within 24 hours, please contact us to confirm that your photographs have arrived.

The appearance of a patio after cleaning depends partly on the material beneath the staining. Different paving surfaces have different textures, compositions and levels of porosity, which influence the treatment required.
Our experience includes working with:
Sandstone: Natural paving with distinctive colour variations that can become obscured by algae and other organic growth.
Limestone: Stone that requires a cleaning product suitable for its composition and existing condition.
Reclaimed York stone: Traditional paving where deeply established staining may require more than one treatment application.
Travertine: Natural stone with characteristic pores and surface variations that need to be considered during cleaning.
Porcelain: Manufactured paving with a dense finish that can still accumulate algae and other organic deposits.
Concrete paving flags: Common patio slabs that can develop green staining, moss and lichen.
Block paving: Individual paving units where organic growth can accumulate across the blocks and within the joints.
You don't need to know the exact material before contacting us. We can consider the paving and select a suitable cleaning formulation.
Our Patio Deep Clean is designed for paving affected by established organic staining, particularly where ordinary washing has failed to remove the deposits responsible for discolouration.
We use specialist patio cleaning products developed by our company, choosing a formulation suited to the surface.
The treatment is applied to address algae, moss, lichen and other suitable organic deposits. Once it has had sufficient time to work, we complete the cleaning with a light pressure wash.
This approach reduces the need for excessive water pressure, which can damage certain paving materials or disturb pointing.
Our products are biodegradable and acid free, and the area is left pet friendly once cleaning has been completed.
The objective is to remove accumulated organic growth and reveal more of the paving's natural appearance, although the finished result will depend on the material and its condition.
Not every discoloured patio needs replacing, and not every cleaning problem can be solved by simply increasing the pressure of the water.
With experience cleaning more than 1,000 patios annually, our team understands how different surfaces respond to specialist treatments and how organic deposits can affect their appearance.
We've also developed our own cleaning products, allowing us to select formulations suited to natural stone, porcelain, concrete paving and other materials.
For Gosport homeowners, this means you don't need to identify the exact cause of every mark or choose a cleaning chemical before making an enquiry.
We can explain whether your patio would benefit from a comprehensive Deep Clean, an Annual Refresh or a preventative Spray and Leave Treatment.
Our focus is on helping homeowners improve their existing outdoor paving through professional cleaning, with practical maintenance options available for the years ahead.
