Fix damp issues in your Newhaven home

There is something about the air in Newhaven, isn't there? Between the salt spray from the English Channel and those brisk winds hitting the hills, our local homes really take a battering. If you've started noticing that tell-tale musty smell or a suspicious dark patch on your wallpaper, you aren't alone. Most homeowners we chat to in the BN9 area tell us they've been 'keeping an eye' on a damp spot for months, hoping it might just go away. At Portslade Plastering, we know that damp is more than just an eyesore; it’s a threat to your property's structure and your family's health. We’ve been helping neighbours across Newhaven and Lewes dry out their homes for years, combining technical expertise with the kind of care you’d expect from a local team.

Expert Damp Proofing Treatments in Southwick & West Sussex

Stop rising damp with professional DPC injection

Ever wondered why the bottom of your ground-floor walls feels cold or looks bubbly? That is often rising damp, where moisture travels upwards from the ground through capillary action. It’s a common headache in Newhaven’s older Victorian and Edwardian terraces that often lack a modern damp proof course. We don't just mask the problem. We treat it at the source using high-performance chemical DPC injections. Our team carefully drills into the mortar line and injects a silicone-based cream that creates a permanent barrier against moisture. It is a tidy, effective way to keep the ground water where it belongs—outside and under your house, not in your living room.

Beat penetrating damp from coastal storms

Living so close to the ferry port and the coast means our external walls face some of the harshest weather in East Sussex. When wind-driven rain hits your brickwork, it can find its way through tiny cracks in the mortar or failed render, leading to penetrating damp. You might see damp patches appearing after a heavy storm or notice 'efflorescence'—that white, powdery salt that ruins your paintwork. We specialise in identifying these entry points. Whether it’s a simple case of faulty pointing or the need for a more robust solution like our silicone rendering or monocouche rendering, we’ll make sure your home is watertight against the elements.

Control condensation and banish black mould

Have you noticed water beads on your windows in the morning or black spots appearing in the corners of your bathroom? That is condensation, and in a coastal town like Newhaven, the humid sea air often makes it worse. It’s not just a cleaning nuisance; black mould can be really tough on your lungs. We help homeowners regain control of their indoor air quality. Sometimes it’s as simple as improving airflow with Positive Input Ventilation (PIV) systems, and other times we might suggest external wall insulation to keep your walls warmer. Whatever the cause, we'll provide an honest diagnosis and a plan to keep your home fresh and mould-free.

Enjoy a flawless finish after damp repairs

The biggest worry we hear from people is the mess. Many damp proofing companies will fix the wall but leave you with a rough, sandy finish that looks nothing like the rest of the room. That is where we are different. Because we are expert plasterers first, we handle the entire process. Once we've hacked off the salt-contaminated plaster, we use specialist waterproof renders and finishing plasters to ensure your wall is 'good as new'. Our internal plastering and skimming service means that once we’re done, you’ll have a perfectly smooth, bone-dry surface ready for decorating. We take pride in our clean and tidy workmanship—we’ll treat your home with the same respect we’d treat our own.

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.
