Stop damp ruining your Littlehampton home

Living so close to the Arun and the coast is lovely, but it does mean our houses take a bit of a battering from the moisture. Whether you've noticed a suspicious musty smell in the hallway or seen those dreaded dark patches creeping up your wallpaper, damp isn't something you want to ignore. At Portslade Plastering, we've spent years helping our neighbours in Littlehampton and across West Sussex get their homes back to being bone-dry and comfortable. We don't just slap a bit of plaster over the problem; we get to the bottom of why the moisture is getting in and fix it for good.

Expert Damp Proofing Treatments in Southwick & West Sussex

Tackling rising damp at the root

Rising damp is a bit of a nightmare for many of the older Victorian terraces near Littlehampton town centre. It happens when groundwater literally sucks its way up through your bricks like a sponge—what we call capillary action. You might see a 'tide mark' on the wall or find your skirting boards starting to rot. We solve this by installing a new chemical Damp Proof Course (DPC). We inject a specialist silicone-based cream into the walls to create a permanent barrier. Once that's done, we'll hack off any salt-contaminated plaster and replace it with specialist materials to make sure those nasty 'hygroscopic salts' don't keep drawing moisture from the air.

Beating the West Sussex coastal weather

If you're closer to the seafront, your home is likely dealing with wind-driven rain. This often leads to penetrating damp, where water finds a way through failed render, cracked pointing, or even blocked gutters. It's especially common in the flint-walled cottages and older semis around the Arun district. We'll take a proper look at your exterior to find the culprit. Sometimes it's a simple repair, other times you might need a more robust solution like our modern silicone or monocouche rendering. As approved PRB Systems contractors, we can apply finishes that are breathable but completely weatherproof, keeping the driving rain out of your living room.

Banish condensation and mould patches

Most homeowners we speak to in Littlehampton are worried about black mould. Often, this isn't a structural leak but a condensation issue caused by modern living. Cooking, showering, and drying clothes indoors create massive amounts of moisture that get trapped. If your windows are steaming up and mould is growing in the corners of your bedroom, we can help. We provide practical advice on ventilation and can install Positive Input Ventilation (PIV) systems that keep the air moving and the mould at bay. It's about making your home a healthier place for your family to breathe.

Professional plastering for a dry finish

One thing that sets us apart from general damp companies is our background in high-end plastering. Once the damp is cured, you don't want a lumpy, unfinished wall. We're experts at internal plastering and skimming, meaning we'll leave your repaired walls perfectly flat and ready for decorating. Whether we've had to replace boards, install a damp-proof membrane, or repair ceiling damage from a leak, we take pride in our 'good as new' finish. We treat your home with respect too—we use plenty of dust sheets and always tidy up properly before we leave. You won't be left with a mess to clean up once the kettle's boiled.

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.
