Stop damp from damaging your Shoreham home

Living so close to the Adur and the English Channel is one of the best things about Shoreham-By-Sea, but that coastal air certainly keeps us on our toes. Between the driving salt spray and the high water table near the river, it's no surprise that many of our neighbours struggle with damp. Have you noticed a musty smell that won't go away, or perhaps some bubbling paintwork near your skirting boards? These aren't just cosmetic issues; they're signs that moisture is finding its way into your property's structure. At Portslade Plastering, we've spent years helping homeowners across Shoreham, from the Victorian terraces near the station to the salt-whipped properties on Shoreham Beach, reclaim their homes from damp for good.

Expert Damp Proofing Treatments in Southwick & West Sussex

Understanding rising damp and capillary action

Most homeowners we speak to in Adur worry that every damp patch is 'rising damp', but it's often a bit more complex. Rising damp happens when groundwater travels up through your bricks and mortar via capillary action—think of it like a sponge soaking up a spill. Many older homes around Shoreham Green were built without a modern Damp Proof Course (DPC), or the original one has simply failed over the last century. We specialise in installing chemical DPC injections using high-grade silicone creams. This creates a new, invisible barrier that stops water in its tracks. Because we're also expert plasterers, we don't just leave you with a treated wall; we hack off the old, salt-contaminated plaster and replace it with specialist waterproof renders, leaving you with a flawless interior finish ready for decorating.

Protecting Shoreham properties from penetrating damp

In a coastal town like Shoreham-By-Sea, penetrating damp is a common culprit. When those Southwesterly storms hit the coast, rain is driven with incredible force against your external walls. If your pointing is cracked, your render is blown, or your gutters are blocked, that water will eventually find its way inside. You'll often see this as isolated damp patches that get worse after a heavy downpour. We don't just treat the symptom; we find the source. Whether it's a failed render that needs replacing with a modern PRB silicone system or a simple repair to your external brickwork, we'll make sure your home is watertight. Our status as Approved PRB Systems Contractors means we use high-performance materials designed to withstand the harsh West Sussex coastal environment.

Solving condensation and black mould issues

Is your bathroom mirror constantly fogged up, or have you spotted black spots appearing in the corners of your bedroom? Condensation is incredibly common in Shoreham's mid-century housing stock, where ventilation often isn't quite up to modern standards. When warm air hits cold walls, it turns into water droplets, leading to mould growth that can affect your family's health. We provide practical condensation control solutions, from simple advice on airflow to the installation of Positive Input Ventilation (PIV) systems. These systems gently circulate fresh, filtered air throughout your house, pushing out the moisture-heavy air and keeping your home bone-dry and healthy. It's often a much simpler fix than people expect, and it makes a world of difference to the 'feel' of a room.

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.
