Damp and Timber Surveys in Birmingham

We provide solutions for rising damp, condensation, timber decay, and basement waterproofing.

Every survey is carried out by our qualified surveyors, and our services are supported by more than 70 years of experience.

Most of our treatments come with a 20-year guarantee, providing you with peace of mind and lasting protection. Early identification of damp and timber issues helps prevent costly repairs and ensures your home, business or project stays dry and fit for purpose.

If you've spotted signs like damp patches on walls, bubbling plaster, or discolouration on interior walls, you could have a rising damp problem, and require damp proofing.

Rising damp occurs when moisture from the ground rises through masonry due to the absence or failure of a damp proof course (DPC), or if an existing damp proof course is bridged.

A damp survey is used to accurately diagnose and confirm whether the issue is rising damp, and offer effective treatment solutions tailored to the specific property if necessary.

Rising damp is more likely in buildings constructed before damp proof courses were commonly installed, or where an existing damp proof course has deteriorated over time. In

Birmingham, contributing factors often include:

• Raised external ground levels like patios or driveways that allow moisture to bridge the damp proof course
• Porous building materials
• Ageing or failed damp proof courses in older properties

Depending on our findings during the damp and timber survey, your treatment plan may involve:

• Installing a chemical damp proof course to create a barrier against rising moisture
• Salt retardant plastering to prevent hygroscopic salts from damaging interior finishes
• Replastering services to restore walls ready for redecoration
• Repair or replacement of structural timbers affected by fungal decay

We are trained in identifying and treating wet and dry rot in buildings throughout Birmingham and the wider West Midlands.

Many of Birmingham’s older properties—particularly Victorian terraces and pre-war homes, are vulnerable to timber decay typically due to long standing issues. This can be anything from plumbing leaks, to poor ventilation, and damp ingress from structural defects.

Combined with the region’s rainfall, these factors create ideal conditions for fungal decay to develop.

Timber rot in Birmingham properties often stems from consistent moisture exposure, commonly caused by:

• Leaking roofs, gutters, or downpipes
• Rising damp or plumbing leaks
• Poor ventilation in crawl spaces or underfloor voids
• High humidity levels and condensation
• Blocked or broken drainage

Wet rot typically affects timber at the source of moisture, causing it to soften and lose strength. Dry rot will spread from the source, even through brickwork, in search of more timber to attack, and can cause serious structural damage if not caught early.

Both thrive in properties with limited ventilation or inadequate damp protection.

Our experienced surveyors carry out thorough timber inspections, diagnosing the type of fungal decay and the extent of the problem, before recommending a tailored treatment plan.

They will look for signs including cracked timber, musty smells, fruiting bodies and fungal strands. They will take the time to fully investigate the extent of the problem, the source of the moisture feeding the fungal decay, and provide detailed recommendations for any treatments necessary.

At Peter Cox Birmingham, our timber treatment services are designed to deliver long-term protection. After a detailed survey, our team will:

• Identify and remove the source of moisture
• Cut back decayed timber and apply professional fungicidal treatments
• Replace or reinforce affected structural timbers
• Recommend and implement ventilation improvements where necessary

Every property is different, which is why our treatments are designed with each home's construction in mind.

Peter Cox offers expert woodworm treatment services for homes and commercial properties throughout Birmingham and the West Midlands.

Many of Birmingham’s properties feature original timber beams, floors and joinery that are vulnerable to woodworm infestations. Woodworm larvae can tunnel through wood and cause significant damage if left untreated to both cosmetic and structural timber. 

Woodworm often target older timber in damp or poorly ventilated spaces such as lofts, basements or subfloor voids.

Following a detailed survey of the property, and an infestation has been confirmed, our Birmingham team will recommend an effective and safe treatment plan to protect your timber in the survey report.

This typically includes:

• The application of a surface insecticidal treatment of affected timbers - applied by spraying, fogging or brush treatment - which kills the emerging beetles on contact as they exit the timbers.
• Timber repair and replacement may be necessary in cases of severe infestation, restoring structural strength.

All work is carried out in accordance with health and safety standards using treatments that are effective, low odour and non-flammable.

Alongside damp proofing, woodworm treatments and solutions for fungal decay, we can also provide a range of other property preservation services to protect and maintain your premises.

• Penetrating Damp Control
• Condensation
• Wall Tie Repairs
• Structural Repairs

We can offer basement waterproofing services designed to meet British Standard 8102 standards across the West Midlands. Our dedicated waterproofing team  can work with you at any point 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.
