Stop damp from damaging your Crawley home

Finding a damp patch on your wall is never a great start to the day. Whether it's a musty smell in the spare room or salt stains appearing on your hallway skirting boards, damp is one of those problems that only gets worse the longer you leave it. Living in Crawley, we get our fair share of West Sussex rain, and for many of the older properties around the town centre or the more exposed homes out towards Pease Pottage, the weather can really take its toll. At Portslade Plastering, we don't just cover up the symptoms; we get to the bottom of why your home is holding onto moisture. From Victorian terraces with ageing brickwork to modern builds struggling with ventilation, we've spent years helping Crawley homeowners keep their properties bone-dry and healthy.

Expert Damp Proofing Treatments in Southwick & West Sussex

Professional damp surveys without the jargon

Most people we talk to are worried that 'damp' automatically means a massive, expensive bill. The truth is, not every damp spot is a disaster. It could be something as simple as a blocked air brick or a leaky gutter that's been dripping onto your brickwork for months. That's why we offer a free, no-obligation damp survey across Crawley. We'll come out, use our moisture meters to see what's actually going on, and give you an honest appraisal. We aren't here to sell you a treatment you don't need. If it's a quick fix, we'll tell you. If it's something more technical like rising damp caused by capillary action, we'll explain the process of installing a new chemical damp proof course (DPC) in plain English so you know exactly what the plan is.

Beating rising damp and salt contamination

Rising damp is a bit of a classic in older West Sussex properties where the original damp course has failed or was never there to begin with. You'll often see it as a tide mark on the lower part of your walls. What's actually happening is ground water is being sucked up through the bricks. This water carries hygroscopic salts which stay in your plaster even after the wall dries out. These salts are like magnets for moisture in the air, meaning your wall will always feel damp until that plaster is removed. Our specialist team doesn't just inject a new silicone-based DPC; we hack off the salt-contaminated plaster and replace it using professional-grade materials. This ensures your final internal plastering and skimming finish stays flawless for years to come.

Fixing penetrating damp from West Sussex storms

When the wind picks up and the rain lashes against your house, any small crack in your render or gap in your pointing becomes an entry point for water. This is penetrating damp, and it's a common headache for Crawley residents. If you've noticed damp patches that seem to appear after a heavy downpour, your external walls are likely the culprit. As approved PRB Systems contractors, we're experts at diagnosing external failures. We can repair damaged brickwork, fix failed render, or even install modern monocouche or silicone rendering systems that act as a high-performance shield for your home. By stopping the moisture at the source, we protect the structural integrity of your property and keep the warmth inside where it belongs.

Tackling condensation and black mould growth

Have you noticed black spots appearing around your window frames or in the corners of your bedroom? In many Crawley homes, especially those with modern double glazing and no trickle vents, condensation is the main enemy. When moist air has nowhere to go, it settles on cold surfaces, leading to mould that can affect your health. We provide practical condensation control solutions, from improving natural airflow to more advanced options like Positive Input Ventilation (PIV) systems. We also deal with the aftermath, including black mould remediation and specialist damp repairs, to make sure your living space is clean, safe, and pleasant to live in again.

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.
