Understanding Different Types of Damp
Damp problems can significantly affect your property's condition and your quality of life. Understanding the different types of damp is crucial for effective treatment:
Rising Damp
Ground moisture rising up through walls due to capillary action. Typically affects ground-floor walls up to 1.2m high and often requires a chemical damp proof course injection to prevent further moisture ingress.
Penetrating Damp
Water entering horizontally through external walls, often due to defective guttering, damaged pointing, cracked render or porous masonry. Requires targeted external repairs and waterproof treatments.
Condensation
Occurs when warm, moist air contacts cold surfaces, creating water droplets that can lead to mould growth. Solutions include improved ventilation, insulation upgrades, and moisture management systems.
Lateral Damp
Found in basements or properties built into slopes where ground water pressure forces moisture through walls below ground level. Requires specialised tanking systems to create a waterproof barrier.
Salt Damp
Results from salt contamination in walls, which attracts and holds moisture. Often appears as efflorescence (white powdery deposits) and requires specialist treatment to neutralize salts.
Plumbing Damp
Caused by leaking pipes, water lines, or drainage problems within or near walls. Requires plumbing repairs alongside damp treatment to fully resolve the issue and prevent recurrence.
Each type of damp requires specific diagnosis and treatment approaches. Our expert surveyors are trained to identify the exact nature of your damp problem and recommend the most effective solution for long-term protection.

The Importance of Professional Damp Proofing
Addressing damp problems promptly and professionally is essential for several important reasons:
- Protects structural integrity - Persistent damp can weaken mortar, timber, and other building materials, potentially leading to serious structural issues if left untreated.
- Prevents health problems - Damp environments promote mould growth, which can trigger allergies, respiratory problems, and other health issues, particularly affecting children and those with existing respiratory conditions.
- Reduces energy costs - Damp walls conduct heat away from your home more rapidly than dry walls, making your heating system work harder and increasing energy bills.
- Preserves property value - Damp issues can significantly decrease your property's value and marketability. Professional damp proofing protects your investment.
- Prevents decorative damage - Damp causes unsightly stains, peeling wallpaper, flaking paint, and damaged plasterwork, requiring frequent redecoration if the underlying issue isn't addressed.
Our professional damp proofing solutions address the root cause of moisture problems, not just the symptoms, ensuring long-lasting protection for your property and peace of mind for you.

What Our Customers Say
"After struggling with persistent damp in our Victorian terraced house for years, Berkley Roofing finally resolved the issue with their rising damp treatment.

Frequently Asked Questions
How can I tell if my property has a damp problem?
Common signs of damp include visible water stains on walls or ceilings, peeling wallpaper or paint, a musty smell, visible mould growth, deteriorating plaster, and salt deposits (efflorescence) on walls. You might also notice wooden elements like skirting boards or window frames becoming warped or rotting. If you spot any of these signs, we recommend arranging a professional damp survey to accurately diagnose the type and cause of damp.
What is the difference between rising damp and penetrating damp?
Rising damp occurs when ground moisture travels upward through walls by capillary action, typically affecting ground floor walls up to 1.2 metres in height. It is often caused by absent or failed damp proof courses. Penetrating damp, on the other hand, moves horizontally through walls and may appear at any height. It is typically caused by external issues like defective guttering, damaged pointing, cracked render, or porous brickwork that allows water to enter the building from outside.
How long does damp proofing take to complete?
The duration depends on the type and extent of damp problem. Simple chemical damp proof course injections might be completed in 1-2 days, while more extensive work like basement tanking or combined treatments could take 1-2 weeks. After treatment, walls normally need time to dry out before redecoration, which can take several months depending on conditions. We will provide a clear timeline specific to your project before work begins.
Will damp proofing work disrupt my daily life?
We strive to minimise disruption during damp proofing works. Most treatments require access to affected areas, which may involve moving furniture and lifting floor coverings near walls. For chemical DPC injections, plaster is typically removed to a height of 1 metre. While there will be some noise and dust, our team works efficiently and employs dust minimisation techniques. We always discuss the practical implications before starting work so you can prepare accordingly.
Do you provide guarantees for your damp proofing work?
Yes, we offer long-term guarantees for our damp proofing treatments. Chemical damp proof courses typically come with a 20-30 year guarantee, while basement waterproofing systems are usually guaranteed for 10-20 years. These guarantees are insurance-backed for your peace of mind and can be transferred to new owners if you sell your property. Specific guarantee periods will be detailed in your quote.
Can I damp proof my property myself?
While DIY damp treatments are available, we strongly recommend professional diagnosis and treatment for long-term success. Incorrect diagnosis is common and can lead to ineffective treatments or even worsening of the problem. Professional damp proofing ensures the root cause is addressed with appropriate solutions and proper application techniques. Our specialists have the expertise, equipment, and access to professional-grade materials not available to the general public.
