Wet Rot and Dry Rot Specialists In Cardiff

Peter Cox specialises in identifying and treating both wet rot and dry rot in residential and commercial properties across Cardiff and surrounding areas.

Our qualified surveyors carry out detailed timber inspections to uncover signs of decay and recommend tailored treatments.

Fungal decay starts when moisture encourages fungal spores (seeds) to germinate, which then take hold and feed on the wood. This occurs when moisture is present over a period of time and can affect buildings with poor ventilation, ageing plumbing, or water ingress from defective roofs, gutters or masonry.

Wet rot typically develops in persistently damp areas and results in timber that is soft, cracked, or discoloured. It stays isolated to the source of moisture, such as roof defects, plumbing leaks, condensation, or rising damp.

Dry rot (Serpula lacrymans) is more aggressive and can travel through masonry to affect timber in other parts of the building. It thrives in poorly ventilated, enclosed or humid spaces and often remains hidden behind walls or under floors until significant damage has occurred.

Treatments are different depending on the type of fungal decay present, making it important for a timber survey to be carried out by a trained professional to determine the type of wood rot affecting a property.

Wet Rot and Dry Rot Treatments In Cardiff

Peter Cox provides expert solutions for fungal decay in Cardiff, so if you’re worried about a wet rot or dry rot problem in your property, we’re here to help.

We can provide you with specialist advice and long term solutions.

After a detailed survey, we provide clear advice on the condition of your timber and what needs to be done. Our treatments focus on stopping the source of moisture and repairing or replacing affected wood to prevent the problem from returning.

Treatment may include:

  • Removing the source of moisture. This can be through damp proofing, ventilation improvements, or fixing building defects
  • Cutting back decayed timber and applying targeted fungicidal treatments where required
  • Cleaning all affected areas of surface growth, including hyphae, mycelium and fruiting bodies, and sterilising walls and masonry where required

Our treatments are carried out by experienced technicians who work to the highest industry standards. At Peter Cox, we’re committed to protecting your property’s structure and value with expert wood rot treatments you can rely on.

Woodworm Treatment Specialists In Cardiff

A woodworm infestation can quietly compromise a building's integrity, leading to severe damage across both structural and decorative timber if left unaddressed.

To protect your property, our local Cardiff team provides expert timber surveys to accurately identify woodworm activity and deliver targeted, professional treatments where required.

Catching an infestation early prevents widespread timber damage and ensures your property stays secure for the future. Our local, fully qualified surveyor will walk you through their findings with a comprehensive, transparent survey report.

Buildings featuring original timber structures are especially susceptible to woodworm attacks, particularly if they suffer from underlying damp or ventilation issues.

Our Woodworm Treatment Solutions

Should our surveyor confirm an active woodworm problem, Peter Cox provides targeted solutions to eradicate the infestation and protect your timbers for the future, maintaining your property’s overall structural integrity.

The process begins with a comprehensive timber survey to identify the specific woodworm species present and determine how far the infestation has spread.

Your written survey report will include all findings and a clear treatment plan.

Treatment typically involves applying a surface insecticidal solution to affected areas, via spraying, fogging, or brush application, to kill the eggs, larvae near the surface, and the beetles on contact as they exit the timbers.

Where severe infestations have compromised structural strength, or there is associated fungal decay, our technicians will carry out necessary timber repairs or structural replacements.

Basement Waterproofing Across Cardiff

Converting a basement or cellar is one of the most effective ways for homeowners to expand their living space and increase property value across Cardiff.

Because below-ground structures are naturally vulnerable to damp and water ingress, professional structural waterproofing is essential to guarantee a dry, well-ventilated, usable environment and protect your property's integrity.

Peter Cox provides comprehensive basement waterproofing solutions designed fully in line with British Standard 8102 (BS 8102). Our team of CSSW-qualified surveyors can assist at any stage of your conversion, whether collaborating early with your architect on initial design plans or inspecting an existing basement structure.

Peter Cox offers a range of basement waterproofing solutions tailored to Cardiff properties, designed to create dry and usable spaces:

  • Type A cementitious tanking systems for robust barrier protection
  • Type C cavity drain membrane systems (CDM) for effective water management, complete with sump and pump installations
  • Combined waterproofing systems for high-risk environments and compliance with NHBC Chapter 5.4, requiring maximum moisture protection

Wall Tie Replacements and Structural Repairs

Cracks in your property's brickwork can often point to underlying structural problems or the need for wall tie replacement.

Across Cardiff, many buildings require structural repairs due to age, natural wear and tear, or external causes like water damage, vibrations, flooding, and subsidence. When wall ties corrode and fail, the inner and outer leaves of a cavity wall lose their connection. This can cause walls to bow, bulge, and eventually risk total collapse.

Peter Cox carries out comprehensive structural inspections to evaluate your wall ties and overall building stability, supplying clear recommendations and repair proposals where necessary. Working alongside structural engineers when required, we are approved installers of specialist Helifix structural tie systems to ensure your property remains secure.
