The architecture of North Wales is defined by stone, a material used everywhere from majestic castles and sturdy cottages to related industrial properties. The region's challenging environment—particularly the wind-driven coastal conditions that affect Victorian terraces and decorative buildings in seaside resorts—makes many properties highly susceptible to preservation issues.

Working with traditional stone building materials presents unique complexities when determining the root causes of damp and timber issues. At Rentokil Property Care, we leverage our many years of specialised expertise to carry out professional surveys. We provide our customers with precise, suitable solutions for any damp and timber related issues, ensuring the unique heritage of North Wales properties is maintained and protected.

Should your property require damp proofing, you can rely on our Rentokil Property Care North Wales team for a professional service from survey to completion. We understand that undertaking such work can be a concern, which is why we guide you through every step of the process. Once recommendations are approved, our highly trained technicians perform all remedial treatments to strict industry standards. They will assess and replace any timbers affected by fungal decay or woodworm, restoring the health of your property. We prioritise minimising disruption; our teams use protective floor coverings and advanced dust extraction units to ensure your property is left clean and tidy.

Property owners often first become aware of fungal decay through signs like a strong musty smell, or by noticing discoloured, cracked, or damaged timbers. This decay falls into two main categories: wet rot and dry rot. Both require moisture in timber to grow, and both will eventually cause the wood to lose its structural integrity.

Dry rot is particularly serious as it can spread away from the moisture source to find new timber to attack, breaking it down and weakening it. If left untreated, a dry rot infestation can travel across an entire floor and even affect different stories of a building. This makes it essential to treat the problem as soon as it is discovered. A qualified surveyor can identify the full extent of the damage and provide clear recommendations for replacing any affected structural timbers.

It is crucial to handle any fungal decay correctly. If you aren't experienced in dealing with it, or if a detailed survey isn't conducted to find the full extent of the outbreak, the rot can return if a moisture source remains. The first step in any effective treatment is always to remove the source of moisture, whether that involves installing effective damp proofing, repairing building defects, or improving sub-floor ventilation.

If you suspect a fungal decay problem in your property, the best course of action is to book a qualified surveyor. They can fully investigate the issue, confirm the type of infestation, and provide you with a detailed proposal to resolve the problem permanently.

Many historic stone cottages and townhouses across North Wales feature low-lying or ground-floor rooms vulnerable to ground water and lateral damp penetration. Converting these spaces into dry, damp-free areas is a smart investment. The process not only could increase your property's value but also frees up valuable space for essential storage, utility rooms, or a comfortable ground-floor space.

The most important thing is to make sure that the newly waterproofed space is correctly installed - if the system fails it can result in substantial water ingress, leading to potential structural issues. This is why it is essential to use an experienced surveyor with a CSSW (Certificated Surveyor in Structural Waterproofing) qualification who will understand the complex nature of waterproofing below ground spaces.

Rentokil Property Care has CSSW qualified surveyors who can design comprehensive basement waterproofing specifications to meet British Standard 8102 the recommended industry guidelines for waterproofing, giving you complete confidence in the long-term protection of your newly converted space.

If you have noticed cracks on your property's brickwork you could have structural problems or may even require wall tie replacement. Most older properties are built with solid walls, however in the 1920's cavity walls became standard as they offer greater protection against wind driven rain and condensation. A wall tie is used to connect the outer and inner walls together at regular intervals, with a cavity in the middle.

Over time these wall ties can corrode, especially if they are exposed to moisture. They become rusty and will expand, causing horizontal cracks in brickwork which are visible along mortar joints.

Thousands of properties across North Wales are affected by corrosion and eventually these wall ties stop functioning, which essentially means the outer leat and inner leaf are no longer connected, and can be susceptible to bowing or bulging. and eventually to total collapse.

Rentokil Property Care can inspect and assess the condition of wall ties, and if required provide a proposal for wall tie replacements. We work closely with structural engineers where necessary, and are an approved installer of Helifix structural products, including wall ties.
