Fix damp problems in your Southwick home

Ever walked into a room and just caught that unmistakable musty odour? Or maybe you've spotted those tell-tale tide marks creeping up the wallpaper just above the skirting boards? Dealing with damp in Southwick can feel like a bit of a battle, especially with the sea air and the wind-driven rain we get hitting our homes along the Sussex coast. At Portslade Plastering, we've spent years helping neighbours from the Victorian terraces near Southwick Green to the more modern semis tucked away near the port. We don't just paint over the problem; we get to the root of why your walls are wet and make sure they stay bone-dry for good.

Expert Damp Proofing Treatments in Southwick & West Sussex

Stop rising damp with professional DPC

Most people don't realise that their walls can act a bit like a sponge. Through something called capillary action, groundwater can literally be sucked up into your brickwork. If your property's original damp proof course (DPC) has failed or was never there to begin with—which is quite common in our older Sussex properties—you’ll start seeing salt stains and peeling paint. We fix this by injecting a specialist silicone-based cream directly into your walls to create a new, waterproof barrier. It’s a clean, effective way to stop moisture in its tracks without needing to rebuild half the house.

Protect your walls from coastal storms

Living so close to the English Channel has its perks, but the horizontal rain isn't one of them. Penetrating damp often hits us hard in Southwick because the salt spray and wind force moisture through tiny cracks in your render or gaps in your pointing. If you’ve noticed damp patches appearing high up on a wall after a storm, that’s likely the culprit. We specialise in identifying these external faults, like leaky gutters or failed rendering, and fixing them before the damage spreads. As Approved PRB Systems Contractors, we can also apply modern, breathable renders that look fantastic and keep the weather out for years to come.

Get rid of black mould and condensation

It’s a common sight in winter: windows dripping with water and those stubborn black spots appearing in the corners of bedrooms or bathrooms. While it’s tempting to just wipe it away, it’ll keep coming back if the airflow isn't right. Condensation is a huge issue in mid-century homes around Adur, but we can help you get it under control. From improving ventilation with PIV (Positive Input Ventilation) systems to simply advising on how to better heat and vent your home, we’ll help you create a much healthier environment for your family. No one should have to live with mould, and we have the tools to stop it.

Repairing the damage properly

One mistake we often see is homeowners just replastering with standard gypsum once the damp source is fixed. The problem is, damp walls are usually full of hygroscopic salts. These salts are left behind when water evaporates, and they actually attract more moisture from the air! That’s why we always hack off the old, salt-contaminated plaster and replace it with specialist waterproof renders. Because we’re expert plasterers at heart, we’ll leave you with a perfectly smooth, skimmed finish that’s ready for a fresh coat of paint. You won't even know we were there—except for the fact that your room is finally dry and cosy.

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.
