Peter Cox has been a trusted name in property preservation since 1951, offering expert support to homeowners and businesses across Sunderland, Tyne and Wear, and the wider North East.
Our surveyors and technicians are specialists in identifying and treating rising damp, woodworm infestations, and wet and dry rot and other property preservation issues.
Our surveyors typically hold industry-recognised qualifications such as CSTDB or CSRT and operate to strict professional standards.
Whether you're dealing with excess moisture in period terraced homes or structural problems in coastal buildings exposed to sea air, we understand the unique challenges properties face and deliver tailored, effective treatments to restore and protect your property.
If you are worried about a damp or timber problem in your home or property, Peter Cox can provide a damp survey to fully investigate and provide you with recommendations for any treatment, where necessary.
A damp survey is used to check the health of your property and identify any damp problems that could affect it, both externally and internally. A thorough survey is essential as preservation issues can be more complex than meets the eye.
Peter Cox provides a range of property preservation services tailored to the properties in Sunderland, and the environmental conditions that impacts them.
From treating damp and condensation problems to delivering effective timber preservation and basement waterproofing, our services are backed by over 70 years of experience.
During your damp survey, our expert will begin with an inspection externally, taking time to note the condition of roof tiles, brickwork, guttering and any high ground levels. If there are building defects this could be the cause of moisture ingress inside the property.
They will then assess internal areas for signs of damp, condensation, woodworm, or timber decay.
You will then receive a clear, detailed report featuring photographic evidence, diagnosis of any issues, and a recommended treatment plan tailored to your property if required.
If you've noticed damp patches near floor level, salty deposits, crumbling plaster, or tide marks on interior walls, your Sunderland property may be suffering from rising damp. Rising damp occurs when moisture from the ground is drawn upward through porous masonry by capillary action, often due to a failed or missing damp proof course (DPC).
Our Peter Cox team covering Sunderland and Wearside specialise in identifying and treating rising damp in a range of property types.
We have over 70 years of experience carrying out damp treatments, tailored to the characteristics of your property. From listed buildings to terraced housing, our surveyors understand the local housing architecture and deliver tailored treatments to solve the problem at the source.
Rising damp occurs in older buildings constructed before modern damp proofing became standard, or properties with a defective damp proof course. Without a functioning damp proof course, moisture can rise through walls, carrying hygroscopic salts that damage plaster and interior finishes.
In Sunderland, factors contributing to damp include:
The most visible indicator is a horizontal tide mark, which is usually found about 1 to 1.2 metres above floor level. This is often accompanied by salt deposits on the surface, flaking paint, soft plaster, and a musty smell. There may also be damage to skirting boards caused by the moisture ingress.
The tide mark paired with salting remains the most reliable visual clue when identifying rising damp.
You should always have an expert carry out a damp survey to confirm the type of damp and advise if damp proofing is necessary.
Our Peter Cox team covering Wearside and South Tyneside delivers effective solutions to stop rising damp and repair any damage caused, often backed by a long term guarantee.
Every treatment starts with a damp survey to identify the source of the damp and extent of the issue.
Depending on the findings, our rising damp treatments in Sunderland may include:
Whether you own a domestic home or are working on a commercial project, Peter Cox is here to restore your property and solve the damp problem.
At Peter Cox, we specialise in detecting and treating wet rot and dry rot in homes and commercial projects throughout Sunderland and the wider Tyne and Wear area.
Our surveyors are experts in identifying wood rot in your property, and can provide you with recommendations for professional treatments to eradicate the problem.
Over time local properties may have problems such as damaged drains, guttering and broken roof tiles, which means moisture from wind driven rain may penetrate into the building. If the conditions are right, wood rot can use this moisture to take hold.
Using proven, targeted methods, we eradicate fungal infestations and work to prevent future outbreaks by removing the source of moisture.
Wet rot and dry rot develop due to prolonged exposure to moisture, which is common because of Sunderland’s coastal weather. Older Sunderland properties with timber features, inadequate ventilation or insufficient damp proofing are particularly susceptible.
Wet rot generally appears in timber with higher moisture content, often caused by leaks or rising damp, but is isolated to the source of moisture. Dry rot can thrive in areas with lower moisture and spreads throughout a property in search of timber to consume, spreading beneath floors or inside masonry.
The treatment processes are different depending on the type of fungal decay, making it important for a survey to be carried out by a trained professional to determine the type of rot affecting a property.
Our timber treatment services focus on addressing the root cause of rot - moisture. Following a detailed survey and approval to proceed, we employ safe and effective treatments tailored to each property’s specific needs.
Treatments may include:
All our work is carried out by local technicians that work to the highest industry standards. At Peter Cox, we’re committed to protecting your property’s structure, value, and peace of mind with expert wood rot care you can rely on.
We provide expert woodworm surveys and treatment services for residential homes and commercial projects across the city.
Our experienced surveyors carefully inspect your property to detect signs of an active infestation, and will assess the extent of any damage. Early identification helps prevent further damage to timber and ensures your property remains safe and sound. They will provide you with a detailed survey report outlining their findings.
There are different species of woodworm which cause damage to timber in different ways, our surveyors are trained to identify the type of infestation to ensure the most effective recommendations.
If signs such as fresh exit holes, frass, or weakened timber are present, we will recommend appropriate treatment in your property report. Our technicians will apply insecticidal treatments to eliminate the active infestation.
In cases where structural timber has been structurally damaged, we will carefully remove and replace it. Our woodworm solutions are designed to provide long-lasting protection, and are applied by trained and experienced technicians.
We have been carrying out expert woodworm treatments across Sunderland, Washington and South Shields for decades.

South Shields is well-known for its coastal charm and stunning beaches. The town features numerous Victorian era terraces and Tyneside flats. Many of these buildings date back to the 19th and early 20th centuries, often featuring solid walls and original timber that can be susceptible to damp and wood decay.
Given its close proximity to the North Sea, properties here frequently encounter challenges from wind driven rain, causing moisture ingress. This can lead to issues such as penetrating damp and corrosion to wall ties.

The cost may vary depending on the size and type of property. A damp survey involves a thorough inspection by a trained surveyor which can take time. They are not just quoting for damp proofing, but fully investigating the source of moisture both externally and internally.
A professional damp survey is carried out by a local surveyor who can accurately diagnose the cause and source of moisture problems, which could help you avoid unnecessary or ineffective repairs. It can also uncover hidden issues that could lead to costly damage if left untreated.
Rising damp in Sunderland is often due to failed or missing damp proof courses in older homes, high external ground levels, or porous materials that absorb moisture. The damp and windy climate in the North East can exacerbate these issues, leading to internal damage if untreated.
We use modern damp proofing techniques such as chemical DPC injection combined with salt-resistant plastering to provide effective, long-lasting protection. Our treatments are tailored to Sunderland’s typical building materials and weather conditions.
If you notice signs of damp, woodworm, or structural problems in your Sunderland property, don’t delay.
