Professional Exterior Wall Cleaning
in Hedge End & Eastleigh
Expert render, brick, and stone cleaning by Under Pressure Southern. Safe algae removal restoring your property's kerb appeal.

Not all wall surfaces should be treated the same way. We understand that modern substrates like K-Render or Monocouche can be easily damaged by aggressive jet washing. Instead of relying on high pressure, we favour a soft washing approach. This involves applying professional-grade biocidal treatments that kill organic growth, such as red algae or lichen, at the root.

Once the treatment has worked, we often follow up with low-pressure steam cleaning to gently lift away the debris. This dual-action process ensures that your walls are thoroughly sanitised without the risk of pitting the surface or forcing water into the building structure. Whether your property is finished in render, pebble dash, or brickwork, our team tailors the approach to match the specific needs of your facade.

We take pride in being a local, fully insured business that residents and property managers in Hampshire trust. Our team is fully equipped to handle projects at height using reach-poles and scaffold systems, ensuring the job is done safely and effectively. We are committed to using eco-friendly chemical solutions that are safe for your pets and garden while adhering strictly to COSHH guidelines for your peace of mind.

Our deep cleaning expertise also includes professional exterior surface restoration, which often pairs well with our wall cleaning services to provide a total home refresh. By removing moisture-retaining moss and algae, we help prevent long-term damp issues that can arise from untreated walls. Our reputation for reliability and quality is why we remain a top choice for property maintenance across the region.

Dirty exterior walls are more than just an aesthetic issue. The accumulation of moss, algae, and atmospheric pollution can trap moisture against your wall, leading to dampness that may eventually impact the interior of your home. By choosing professional cleaning, you are performing a vital piece of maintenance that preserves the structural integrity of your building.

Our team is skilled at identifying the specific contaminants affecting your home, from red algae found in the local area to traffic pollution near major routes. Regular cleaning is a highly cost-effective alternative to expensive re-painting or repairs. To see how we can transform your home, request your free Hedge End wall survey today.

Will pressure washing damage my render? We avoid using high-pressure water directly on render surfaces, opting instead for low-pressure hot water steam and chemical soft washing to ensure no damage is caused.

How long does wall cleaning take? Most domestic projects in Hedge End can be completed within a single day, though this depends on the scale and condition of the building.

Do you need an outside water tap? While having access to an external tap is helpful for our workflow, we are fully equipped to bring our own water supply if necessary, ensuring we can work on any site regardless of utility access.
