How To Stop Dampness On Walls: 9 Quick Tips

11 December 2024

Damp walls are more than just an aesthetic issue; they can weaken structural integrity, promote mould growth, and impact tenant satisfaction. For property managers, landlords and operators alike, addressing dampness is a critical task. This guide shares nine actionable tips on how to stop dampness on walls and highlights how ResiSure’s innovative home monitoring technology can help you stay one step ahead.

1. Ensure Proper Ventilation

Proper ventilation is absolutely vital for preventing damp walls. When moisture-laden air has nowhere to escape, it condenses on cold surfaces, leading to damp patches. A well-ventilated home allows humid air to circulate and disperse, reducing condensation and the risk of dampness. To achieve this, here are some tips…

  • Make sure your tenants know to open windows regularly, particularly after activities like cooking or showering. 
  • In high-moisture areas such as kitchens and bathrooms, installing extractor fans can make a significant difference by actively drawing out humid air. 
  • If your properties lack adequate natural ventilation, consider mechanical ventilation systems to maintain consistent airflow.

2. Heat Your Home Consistently

Keeping your properties warm helps to counteract one of the main causes of dampness: condensation forming on cold surfaces. When indoor temperatures are consistent, it’s harder for moisture to settle on walls, preventing damp and mould spots from forming. Heating a home doesn’t necessarily mean cranking up the thermostat; instead, focus on maintaining a steady temperature. Using programmable heating systems can help regulate heat effectively, ensuring all rooms stay warm and dry, especially during colder months. Properties with stable heating are not only more comfortable but also better protected against damp-related issues.

3. Inspect For Leaks Regularly

Water leaks are a common cause of damp walls, as they allow moisture to penetrate surfaces over time. Regularly inspecting your property for potential leaks is essential to prevent long-term damage. Here are a few tips!

  • Start by examining the roof for missing tiles or damaged areas and clearing gutters to ensure proper drainage. 
  • Inside, check plumbing systems for leaks under sinks, around appliances, or in visible pipework. 
  • Don’t overlook small cracks in walls or foundations, as these can let water seep into your property. 

4. Seal Gaps Around Doors and Windows

Gaps around windows and doors are another common entry point for damp-causing moisture. Sealing these gaps is an effective way to keep your properties protected. Use weatherstripping to block drafts and replace any damaged seals around windows. Cracks or openings in window and door frames should also be sealed with caulk to ensure a tight barrier. By addressing these vulnerable areas, you not only protect against dampness but also improve energy efficiency, reducing heating costs in the process.

5. Remove Condensation Immediately

Condensation is one of the earliest signs of high humidity levels and a precursor to damp walls. If you notice condensation forming on windows, walls, or mirrors, it’s important to act quickly! Here’s what you should do:

  • Wipe surfaces dry as soon as you see moisture to prevent it from soaking into walls and causing long-term damage. 
  • In bathrooms, using a squeegee to clear water from tiles and glass can help reduce lingering moisture. 
  • Pay attention to recurring condensation, as it often signals underlying issues like poor ventilation or inconsistent heating that need to be addressed to prevent future damp problems.

6. Invest in Dehumidifiers and Moisture Traps

Dehumidifiers are an excellent solution for managing indoor humidity levels, particularly in areas prone to dampness. These devices can remove substantial amounts of water from the air—some models extract as much as 30 to 70 pints daily! Placing a dehumidifier in damp-prone areas like basements or poorly ventilated rooms can make a significant difference. For smaller, specific spaces, such as wardrobes or cupboards, moisture traps or silica gel packs offer a simple yet effective solution. While dehumidifiers are highly efficient, they work best when combined with other preventative measures like proper ventilation and heating.

7. Keep Furniture Away From Walls

Furniture placed directly against walls can contribute to dampness by blocking airflow and trapping moisture. Allowing space between your furniture and the walls can improve circulation, making it harder for moisture to accumulate in these areas. A gap of just two to three inches is usually enough to encourage airflow. This simple adjustment ensures that damp-prone areas behind furniture remain dry and well-ventilated, reducing the risk of mould growth and wall damage. Overcrowded rooms with limited space are particularly susceptible, so it’s worth considering more strategic furniture placement.

8. Apply Damp-Proof Paint

Using damp-proof paint is an effective way to create a protective barrier on walls, preventing moisture from penetrating the surface. This type of paint is particularly useful in damp-prone areas such as basements, kitchens, or bathrooms. It works well on a variety of surfaces, including plaster, brickwork, cement, and stone. Before applying damp-proof paint, it’s essential to prepare the wall by cleaning and drying it thoroughly. This ensures the paint adheres properly and delivers long-lasting protection. With its added resistance to mould growth, damp-proof paint is an ideal solution for safeguarding vulnerable areas.

9. Use ResiSure’s Proactive Damp-Tracking Technology

While the previous tips are effective for managing dampness, the most critical step is proactive tracking. Monitoring conditions like humidity and temperature across your property portfolio ensures you can detect problems early and prevent them from escalating. 

ResiSure’s smart home monitoring technology offers an advanced solution for property managers and landlords. Our small, wireless devices track humidity, temperature, and mould risk every 30 minutes, providing real-time data and trends. This information is delivered through a customisable dashboard, allowing you to identify areas at risk and take action before dampness becomes a significant issue. Proactive tracking is a game-changer, helping you maintain healthy living environments while protecting your properties from costly damage.

Why Proactive Property Management Matters

Addressing dampness is about more than just aesthetics; it’s about safeguarding the health and well-being of tenants while protecting the value of your property portfolio. Unchecked damp can lead to structural damage, legal issues, health issues and tenant dissatisfaction, all of which can have long-term repercussions. Preventative measures, combined with ResiSure’s innovative technology, enable you to tackle the root causes of dampness effectively. By taking a proactive approach, you can ensure your properties remain safe, comfortable, and free from damp-related challenges.
