Expert Black Spot Removal for Patios in New Alresford

If your patio in New Alresford has become covered in persistent dark, stubborn spots, you are likely dealing with black spot lichen. These organisms anchor deep into the pores of natural stone and concrete, making them incredibly difficult to shift with standard domestic pressure washers. Under Pressure Southern specialises in professional lichen treatment and surface restoration, helping homeowners across the Winchester and Hampshire area regain a beautiful, clean patio surface.

Expert Black Spot Removal in Hedge End & Eastleigh

As Southampton's trusted exterior surface restoration specialists, Under Pressure Southern safely eliminates stubborn lichen and algae. Using fully insured methods, precise pressure management, and biodegradable stone cleaners, we restore your natural sandstone to its former glory without risking structural damage.

Why Do Black Spots Persist on Your Stone?

Many residents in New Alresford find that despite hours spent jet washing their patios, the dark spots return within weeks. This is because standard pressure washing often only cleans the surface, leaving the lichen spores alive deep within the stone. Our professional approach targets the root of the problem. We use high-grade, biodegradable chemical treatments that safely break down the lichen structure, allowing for effective and thorough removal that leaves your stone looking as good as new.

Our Specialist Cleaning Process for Hampshire Patios

We take a systematic approach to exterior surface restoration. After an initial assessment, we apply a specialist treatment designed to kill off algae and lichen spores without damaging the material. Once the solution has had time to work, we utilise professional-grade pressure washing technology set to the precise pressure required for your specific surface type. This ensures we clean deep into the stone's texture whilst maintaining the structural integrity of your paving, block work, or natural stone.

Safety and Local Compliance in New Alresford

As a professional company, we prioritise safety and environmental responsibility in every job we undertake. We carry full public liability insurance, giving you total peace of mind while we work on your property. We are strictly compliant with drainage regulations, ensuring that all cleaning agents are handled and disposed of safely and correctly. Whether we are cleaning a quiet residential driveway or a larger outdoor space, we manage our water usage and chemical application carefully to protect your garden, pets, and the local Hampshire environment.

FAQ

Black Spot Removal FAQs

Answers to common questions about our professional black spot removal and natural stone patio restoration services across Southampton, Hedge End, and Eastleigh.

What exactly is the black spot on my patio?

+

Those black marks are actually lichens. They thrive in the damp UK climate and thrive on the minerals found in natural stone. They grow into the stone's pores, which is why they don't just wash away with a standard hose or a basic pressure washer.

Will the chemicals you use harm my plants or my dog?

+

We use professional-grade, biodegradable stone cleaners. Once we have finished the cleaning process and rinsed the area thoroughly, the surface is perfectly safe for pets and children. We also take care to pre-wet surrounding grass and plants to protect them during the treatment.

Can you remove black spots from Indian Sandstone without damaging it?

+

Yes, sandstone restoration is one of our specialities. We use a "soft wash" approach combined with professional treatments that lift the spots without needing to use excessive pressure that could delaminate or scar the stone.

How long will it take to clean my patio?

+

Most domestic patios in Hedge End can be completed in a single day. This includes the preparation, treatment application, washing, and a final rinse down. If your patio needs re-sanding, we usually return on a dry day to complete that step.

How often should I have my patio professionally cleaned?

+

To keep black spot and algae at bay, we usually recommend a professional clean and treatment every 12 to 24 months, depending on how much shade and moisture your garden gets.
