Damp Proofing and Timber Repairs - Hull

Peter Cox has been carrying out expert surveys and treatments for homeowners and businesses across Hull 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 are worried about a damp or timber problem in your home in Hull, Peter Cox can provide a professional damp and timber survey to identify any issues and provide you with recommendations.

They will check both the exterior and interior of your property, as exterior defects can often lead to water penetration and damage inside.

They will use specialist tools such as moisture meters and thermal imaging cameras to identify signs of damp and condensation. Surveyors will also check the condition of timber to make sure no fungal decay or woodworm has been caused by damp ingress.

The survey will be at a mutually agreeable time, so we can discuss any damp and timber issues that need to be addressed.

All findings will be detailed in a survey report, outlining the need for treatments, but only if they are required. Most of our treatments come with a 20-year guarantee to ensure long-lasting solutions for your property.

Due to local property age and annual rainfall, damp proofing is a frequent necessity for homes and businesses across Hull. Without proper care, issues like rising damp, penetrating damp, condensation, and mould can quickly compromise your building.

If you suspect moisture damage, our specialists will conduct a thorough survey to pinpoint the exact type and extent of the issue before recommending targeted, long-term solutions. When repairs are needed, our expert technicians, highly skilled in specialist damp proofing and joinery, execute every job to the highest industry standards.

We respect your home throughout the process. Using commercial dust extraction units, vacuums, protective floor coverings, and heavy-duty sheeting, our team works efficiently to minimise mess and leave your property spotlessly clean.

Across Hull and surrounding areas, Peter Cox provides expert diagnosis and specialist treatment for both wet rot and dry rot in homes and commercial premises.

To determine the full extent of fungal decay and provide effective solutions, our qualified surveyors carry out thorough timber inspections. Decay develops when prolonged moisture enables spores to germinate and feed on structural wood, a common issue caused by poor ventilation, leaking plumbing, or water ingress from damaged roofs and gutters.

Wet rot thrives in continuously damp environments, leaving timber soft, cracked, or discoloured. It remains localised around the moisture source, such as plumbing leaks, roof defects, condensation, or rising damp.

Dry rot (Serpula lacrymans) is far more invasive, capable of traveling through masonry to compromise uninfected areas. It flourishes in hidden, poorly ventilated spaces like subfloors and wall cavities, often causing extensive damage to timber before being noticed.

Because wet rot and dry rot require completely different remedial techniques, an accurate survey by a trained professional is essential to identify the precise fungal decay affecting your building.

If you suspect wet rot or dry rot in your Hull home or business, Peter Cox is here to support you with expert advice and long-term fungal decay solutions.

Following a thorough timber inspection, our specialists deliver clear findings on your property's structural health alongside a practical plan of action. Our core approach centres on stopping the source of moisture at its origin, then repairing or replacing damaged wood to ensure complete, lasting protection.

Treatment may include:

• Stopping the moisture source by installing damp proofing, improving property ventilation, or repairing external defects
• Removing decayed timber section by section, as required, and applying specialised fungicidal treatments to surrounding areas if required
• Thoroughly cleaning surface growth, including hyphae, mycelium, and fruiting bodies, while sterilising affected walls and masonry as required

Every repair is performed by fully trained technicians adhering strictly to industry standards. Partner with Peter Cox to defend your property’s structure and safeguard its long-term value with trusted, professional wood rot treatments.

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 Hull 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.

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.

Many properties in Hull feature basements or cellars, which many homeowners look to convert to valuable additional living or storage space, while also adding value to the property.

Below ground spaces are often susceptible to damp problems and water ingress, making structural waterproofing essential to ensure their usability and protect the structural integrity of the property. Improvements to ventilation will also be required to prevent issues with condensation.

Peter Cox offers comprehensive basement waterproofing services designed to meet British Standard 8102 (BS 8102).

Our dedicated waterproofing team of CSSW (Certificated Surveyor in Structural Waterproofing) qualified surveyors can work with you at any stage of your project, whether it be at the start of the project with your architect when creating design plans, or beginning with a survey of an existing structure.

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

• Type A cementitious tanking systems for barrier protection
• Type C Cavity drain membrane systems (CDM) for water management, with sump and pump installations to manage water ingress
• Combined waterproofing systems for high-risk situations and compliance with NHBC Chapter 5.4, ensuring maximum protection

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

Across Hull, 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.
