Expert Damp Proofing Treatments in Southwick & West Sussex

Stop Rising Damp ruining your walls

Most of the older properties we see around Burgess Hill were built long before modern damp-proof courses were standard. Rising damp happens when ground water literally climbs up through your bricks via capillary action—think of it like a sponge sitting in a puddle. You'll usually see it as a tide mark on the lower part of your walls, often accompanied by white, powdery efflorescence. To fix this, we use a specialised chemical DPC injection. This creates a new, waterproof barrier within the wall to stop moisture in its tracks. Because we're plastering experts first and foremost, we don't just 'inject and run'. We'll carefully remove the salt-contaminated plaster and replace it with a specialist render that won't let those nasty salts through to your new paintwork.

Keep the Mid Sussex weather outside

Sometimes the damp isn't coming from the ground; it's coming straight through the walls. In West Sussex, our homes take a fair beating from wind-driven rain. Penetrating damp often starts with something small—a cracked bit of pointing, a leaky gutter, or a patch of failed render. Before you know it, you've got a damp patch on the inside that won't go away. We'll take a proper look at the exterior of your property to find the culprit. From traditional sand and cement repairs to modern silicone rendering and monocouche rendering, we have the tools to seal your home tight against the elements. If your exterior walls are looking a bit tired, we can even chat about external wall insulation to keep the heat in while we're at it.

Banish black mould and condensation

Is there anything more frustrating than black mould appearing around your window frames or behind the wardrobe? Most homeowners tell us they've tried every spray under the sun, only for the spots to come back a month later. This is usually down to poor airflow and condensation. In many Burgess Hill homes, especially those that have been sealed up with modern double glazing, the moisture simply has nowhere to go. We offer practical condensation control solutions, including PIV (Positive Input Ventilation) systems that keep the air moving and the mould at bay. It’s about creating a healthy environment for your family to breathe in, not just masking the problem with a fresh coat of paint.

Book your free honest damp survey

We know what you're thinking—is this going to cost a fortune? The truth is, not all damp requires a massive structural overhaul. Sometimes, it’s just a blocked air brick or a garden path that’s been built up too high, causing 'bridging' over your existing damp course. That’s why we offer a free, no-obligation damp survey across Mid Sussex. We'll give you a straight-up, honest diagnosis. We aren't here to sell you a treatment you don't need; we're here to protect your home’s value and your peace of mind. As a fully insured, PRB Systems approved contractor, we pride ourselves on being reliable and, most importantly, tidy. We treat your home like our own, ensuring your floors are protected and the kettle is the only thing we leave out of place. Ready to dry out your home? Give our friendly team a call on 01273 957212 and let’s get it sorted.

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.
