Expert Damp Proofing Treatments in Southwick & West Sussex

Get a proper damp survey

Most people assume a damp patch means they need a whole new damp proof course, but that is not always the case. It could be something as simple as a blocked air brick or a leaky gutter dripping onto your brickwork. We believe in an honest diagnosis. When you book a free damp survey with us, we will not try to sell you a solution you do not need. We look for the 'why' behind the moisture. Is it rising damp caused by capillary action, or is it penetrating damp coming through failed render or faulty pointing? We will give you a clear, no-nonsense breakdown of what is happening and the most cost-effective way to put it right.

Banish rising damp for good

Rising damp is a common headache in Brighton's older housing stock, where original damp proof courses have either failed or never existed. You will usually spot it as a 'tide mark' along the bottom of your walls, often accompanied by crumbling plaster or peeling wallpaper. We tackle this by using professional-grade chemical DPC injections. This silicone-based cream creates a new waterproof barrier within your bricks, stopping groundwater from climbing up. To finish the job properly, we remove any salt-contaminated plaster and replace it with specialist materials that prevent those pesky hygroscopic salts from attracting moisture in the future.

Shield your walls from storms

Penetrating damp is the classic coastal problem. When those winter storms hit the Brighton seafront, rain is driven with incredible force against your external walls. If your render is cracked or your brickwork is porous, that water will eventually find its way inside. We specialise in identifying these external faults. As approved PRB Systems contractors, we can repair your external render or apply modern, breathable silicone rendering that acts like a raincoat for your house. It keeps the moisture out while letting the building breathe, which is vital for preventing long-term structural damage and timber decay like dry rot.

Control condensation and black mould

Have you noticed black spots appearing around your window frames or in the corners of your bathroom? This is usually condensation, and it is a major concern for many Brighton tenants and homeowners. It happens when warm, moist air hits cold surfaces, and it can lead to serious health issues if left untreated. We offer practical advice and moisture control solutions, from improving ventilation to installing PIV (Positive Input Ventilation) systems. We do not just wipe away the mould; we help you change the environment in your home so it never comes back, ensuring your family stays healthy.

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.
