Stop damp from damaging your Southwick home

Living so close to the Sussex coast has its perks, but the salt-heavy air and wind-driven rain can take a real toll on our properties. If you've spotted a tide mark on your wallpaper or noticed a musty smell in the spare room, you aren't alone. Many homeowners around Southwick and the Adur district face these exact issues, especially with the beautiful Victorian and Edwardian terraces near Southwick Green. At Portslade Plastering, we don't just cover up the problem; we get to the bottom of why your walls are wet and provide a long-term fix that keeps your home warm and dry.

Expert Damp Proofing Treatments in Southwick & West Sussex

Identify the cause before you spend

One of the biggest mistakes we see is people rushing into expensive treatments without knowing what's actually wrong. Is it rising damp, or is it just a leaky gutter? Not every damp patch requires a brand-new damp proof course. When we visit your property for a free survey, we look for the 'why'. We'll check for bridging—where garden soil or debris has built up against the wall and bypassed your original DPC—and we'll look for faulty pointing or cracked render that's letting the coastal rain soak through. We believe in honest advice that saves you money in the long run.

Solve rising damp for good

Rising damp happens when groundwater climbs up through your bricks via capillary action, much like water soaking up through a sponge. In older Southwick properties where the original slate or bitumen barrier has failed, this brings up hygroscopic salts that linger in your plaster and keep attracting moisture. Our team specialises in chemical DPC injections, using high-performance silicone-based creams that create a permanent water-repellent barrier. Once we've stopped the moisture at the source, we'll hack off that salt-contaminated plaster and replace it with specialist materials to ensure the damp never returns to the surface.

Protect against penetrating coastal rain

Properties in the BN42 area are right in the firing line for Southwick's famous coastal storms. Penetrating damp occurs when moisture is pushed through the external envelope of your building. This often happens because of failed render or 'spalled' brickwork that has become porous over time. As approved PRB Systems contractors, we can repair your exterior using modern, breathable renders that act like a Gore-Tex jacket for your house—letting moisture out while stopping the rain from getting in. It’s about more than just aesthetics; it's about structural preservation.

Eliminate condensation and black mould

Not all damp comes from the outside. If you're seeing black mould in the corners of your rooms or water streaming down the windows in the morning, you’re likely dealing with condensation. This is incredibly common in mid-century homes and modern flats where airflow isn't quite right. We offer practical solutions ranging from simple ventilation improvements to the installation of Positive Input Ventilation (PIV) systems. These units gently circulate fresh, filtered air throughout your home, pushing out the moisture-laden air that causes mould growth and protecting your family's health.

FAQ

Damp Proofing FAQs

Answers to common questions about our damp proofing treatments and specialist property repairs in Southwick, West Sussex and Portslade, Brighton & Worthing

How can I tell if my Southwick property has a damp problem?

+

It isn't always obvious at first. You might notice a bit of a musty smell when you walk into a room, or see white, crusty salt patches appearing on your internal walls. Other common signs in local homes include peeling wallpaper, skirting boards that feel soft or look wavy, and black mould spots in the corners of the ceiling. Because Southwick is so close to the coast, the damp sea air can sometimes make these issues feel worse. It is always best to catch these signs early before they cause real damage to your timber or plaster.

What happens during a professional damp survey?

+

When we visit your home for a survey, we are looking to find exactly where the moisture is coming from. We don't just guess; we use moisture meters to check the levels inside your walls and take a close look at the outside of the building. We check for things like cracked pipes, blocked gutters, or damaged brickwork that might be letting water in. Our goal is to give you a clear, honest picture of what is happening. We focus on practical Adur property repairs that solve the problem rather than just covering it up.

Is rising damp treatment a permanent fix for older houses?

+

Yes, as long as the work is done correctly. Many older Victorian and Edwardian houses in West Sussex were built without a modern damp proof course, which allows water from the ground to soak up into the walls. As West Sussex damp specialists, we fix this by injecting a special cream into the mortar joint that creates a new waterproof barrier. Once we have removed the old, salt-damaged plaster and replaced it with a specialist render, your walls will stay dry. It is a reliable way to make an old house feel warm and dry again.

What is the difference between rising damp and penetrating damp?

+

The main difference is the direction the water is travelling. Rising damp comes from the ground and usually only reaches about a metre up the wall. Penetrating damp is water getting in from the outside, often because of a fault in the building’s exterior. In Southwick, heavy wind-driven rain can be forced through tiny cracks in old render or gaps around window frames. We will identify which one is affecting your home during our visit so we can apply the right fix.

How do I manage condensation control in my flat?

+

Condensation is one of the most common issues we see, especially in the winter. It happens when steam from cooking or showering hits a cold wall or window and turns back into water. While it isn't a structural leak, it can still lead to black mould and a damp atmosphere. We can show you how to improve the airflow in your home, perhaps by installing better extractor fans or vents. Sometimes, adding insulated plasterboard to an external wall can also help by making the surface warmer and less likely to collect moisture.

Will I need major Adur property repairs to fix a damp wall?

+

Not always. People often worry that damp proofing involves a huge amount of mess and construction, but that is rarely the case. Sometimes the fix is quite simple once we find the leak. It might just be a case of repairing a bit of external pointing or clearing a blocked cavity. We take a lot of pride in being tidy, making sure we protect your carpets and furniture while we work and leaving the place clean once the job is finished.
