Damp Proofing and Timber Repairs - Perth

Peter Cox has been carrying out expert surveys and treatments for homeowners and businesses across Perth for over 70 years, identifying and offering effective solutions for a wide range of property problems.

Our experienced surveyors and technicians are experts in diagnosing and treating damp problems, condensation and mould, timber decay and woodworm, as well as structural faults and wall tie corrosion.

We will provide you with thorough advice on the problem affecting your property, along with recommendations to solve the problem and protect the long-term health and value of your property.

If you suspect damp or timber damage in your Perth property, Peter Cox offers comprehensive professional damp surveys to pinpoint the exact cause and deliver clear, actionable recommendations.

Our detailed inspection covers both the interior and exterior of your building, ensuring external defects, which often allow moisture to seep inside, are caught early. Using advanced diagnostic tools, including moisture meters and thermal imaging cameras, our surveyors accurately identify damp and condensation, while thoroughly checking all accessible timbers for signs of fungal decay or woodworm.

We schedule appointments at a time that works best for you, allowing us to discuss your specific concerns in detail. Following the visit, you will receive a comprehensive report outlining only necessary treatments. For added peace of mind, most of our remedial work is backed by a 20-year guarantee to ensure long-term protection.

A combination of older property stock and weather makes effective damp proofing essential across Perth. Left unchecked, properties often suffer from problems such as rising damp, penetrating damp, condensation and mould.

Peter Cox provides expert damp surveys to diagnose the root cause of moisture ingress and map out effective, long-lasting treatments. Should your building require restoration, our qualified technicians deliver high-quality damp proofing and joinery work tailored to your property's specific needs.

We prioritise keeping disruption to a minimum while working in your home. Equipped with modern dust extraction units, industrial vacuums, and full protective sheeting, our technicians ensure your property is left clean, tidy, and fully protected.

Unchecked timber decay can severely compromise structural integrity, which is why Peter Cox offers targeted treatments for wet rot and dry rot across Perth and the surrounding region.

Our qualified surveyors conduct comprehensive timber evaluations to identify active decay and map out tailored repair plans. Fungal decay takes hold when persistent moisture, often stemming from defective gutters, plumbing leaks, damp masonry, or roof damage, allows microscopic fungal spores to germinate and weaken structural timbers.

Wet rot is restricted to persistently damp zones, causing timber to darken or bleach, crack, and soften directly around sources of rising damp, condensation, or leaks.

Dry rot is a far more severe threat that actively spreads through brickwork and mortar to attack surrounding timbers. It thrives in damp, unventilated cavities and under floorboards, often remaining concealed until widespread damage occurs.

Since the required treatments for these two forms of decay differ significantly, getting a professional timber survey is the critical first step in determining the correct, lasting solution for your property.

If you are worried about a wet rot or dry rot issue in your property, Peter Cox delivers expert solutions for fungal decay across Perth.

Our team is on hand to offer specialist advice and effective, permanent treatments. Following a thorough inspection, we provide transparent guidance regarding your property's timbers and what needs to be done. We prioritise eliminating the underlying moisture source while repairing or replacing damaged wood to stop decay from recurring.

Treatment may include:

• Eliminating moisture ingress via damp-proofing solutions, upgraded ventilation, or repairing external property defects.
• Cutting away infected, decayed timber and treating the remaining structure with targeted fungicidal applications as required.
• Removing surface growth such as hyphae, mycelium, and fruiting bodies, alongside sterilising affected brickwork and masonry where necessary.

All work is completed by skilled technicians dedicated to upholding the highest industry standards. Rely on Peter Cox to safeguard the structural health and overall value of your property with proven wood rot treatments.

If left untreated, woodworm can lead to severe damage to both decorative and structural timber.

A surveyor from our local branch covering Perth and the surrounding areas will carry out a timber survey to identify the woodworm infestation in your property and provide professional treatments if it is found to be active.

Early identification helps prevent further damage to timber and ensures your property remains safe and sound. Our local qualified surveyor will provide you with a detailed survey report outlining their findings.

Many properties with original structural timber are vulnerable to woodworm infestations, especially those with ventilation or damp issues.

If one of our surveyors identifies an active woodworm infestation, and you wish to go ahead with the treatment, we can eliminate the infestation and protect your timber, preserving the structural integrity of your property:

• The first step is a timber survey to accurately identify the woodworm species present, assess the extent of the infestation, and any associated moisture source.
• The findings and treatment process will be detailed in the survey report.
• This usually involves the application of a surface insecticidal treatment to affected timbers - applied by spraying, fogging, or brush treatment - which kills the eggs, larvae near the surface, and the beetles on contact as they exit the timbers.
• Timber repair and replacement may be necessary in cases of severe infestation or associated fungal decay, restoring structural strength.

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

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 Perth 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

If you have spotted cracking across your external brickwork, your building may be suffering from structural faults or failing cavity wall ties.

A variety of factors, including property age, general deterioration, water ingress, ground vibration, flooding, and subsidence, lead to structural issues in homes and businesses across Perth. Corroded wall ties break the bond between the inner and outer masonry leafs, leaving structures vulnerable to bulging, bowing, and serious structural failure if left unaddressed.

At Peter Cox, our specialists inspect and assess wall tie conditions to deliver accurate, reliable replacement proposals. Partnering with structural engineers as needed, our qualified technicians install industry-leading Helifix structural products to restore full stability and long-term safety to your property.
