Damp Proofing Specialists in Cardiff

Cardiff and its surrounding areas feature a wide range of traditional Victorian and Edwardian terraced homes, originally built to house a rapidly growing population during the coal and shipping boom. Today, many of these properties are being updated, with basements and former coal storage areas being refurbished into habitable living spaces. If not waterproofed and ventilated correctly, these conversions can lead to issues ranging from mould growth to a risk of flooding, which can cause significant damage. Rentokil Property Care has the expertise to correctly waterproof these spaces, preserving the character of Cardiff's homes while making them suitable for modern living.

Often, the first signs of fungal decay that property owners notice are a strong musty smell or timbers that appear discoloured, cracked, or damaged. This type of decay is categorised as either wet rot or dry rot. Both forms require moisture to germinate on timber, and both will ultimately cause the wood to lose its structural strength.

Dry rot is especially serious because it has the ability to spread away from the original moisture source to find new timber to consume, breaking it down and causing it to weaken. If not treated, a dry rot outbreak can spread across an entire floor and even move to different levels of a property. This is why it is vital to address the problem as soon as you find it. A qualified surveyor can assess the full extent of the damage and provide clear recommendations for replacing any compromised structural timber.

Correctly handling any fungal decay is crucial. The rot can easily return if a moisture source remains, which can happen if you are not experienced in treating it or if a thorough survey isn't performed to identify the full scope of the outbreak. The first step in any successful treatment is always to eliminate the source of moisture. This could involve installing effective damp proofing, fixing building defects, or improving ventilation in areas like sub-floor voids.

If you think you might have a fungal decay problem, your best option is to book a qualified surveyor. They can conduct a full investigation, confirm the type of infestation, and give you a detailed proposal to permanently fix the issue.

Transforming an unused basement or cellar in your Cardiff property is an excellent way to add valuable living space and increase its worth. Whether you envision a home office, gym, or extra storage, the key to a successful conversion is a professionally installed waterproofing system.

It is vital that this work is carried out correctly, as a failed system can lead to major water ingress and significant damage to your belongings. To ensure a reliable and lasting result, it is essential to use a surveyor with the CSSW (Certificated Surveyor in Structural Waterproofing) qualification. Our CSSW-qualified experts design comprehensive basement waterproofing solutions that adhere to British Standard 8102, the industry's code of practice, transforming your below-ground space into a dry and usable area.

If you've noticed horizontal cracks in your brickwork, especially on older properties in areas like Hoole or Handbridge, you may be experiencing cavity wall tie corrosion. Cavity walls, which became standard after the 1920s, use metal ties to connect the inner and outer layers. Over time, these ties can rust and expand, causing visible cracks and weakening the structural integrity of your property.

Left untreated, corroded wall ties can lead to the inner and outer walls becoming disconnected, potentially causing them to bow or bulge. Our Swansea-based team can inspect and assess the condition of your wall ties using specialised equipment. If required, we will provide a proposal for a professional wall tie replacement service. We work with structural engineers when necessary and are an approved installer of Helifix structural products, ensuring a reliable and lasting solution for your property.
