Damp Proofing Services by Action Roofing & Building Services
At Action Roofing & Building Services, we offer expert damp proofing solutions across Liverpool and the wider Merseyside region, drawing on over 30 years of experience to protect your property from the damaging effects of moisture. Our services address common issues like rising damp, penetrating damp, and condensation using the latest techniques, including chemical damp proof course (DPC) injections with high-strength silane-based creams, electro-osmotic systems, wall base ventilation for historic properties, and advanced waterproofing membranes. We conduct thorough surveys to identify the root cause of damp, then apply tailored treatments that are effective, minimally disruptive, and compliant with UK building regulations. Whether it’s a residential home or commercial building, our goal is to deliver long-lasting protection, improve indoor air quality, and enhance your property’s value with reliable, eco-friendly methods.
Our Damp Services and Treatments
Rising Damp Treatment
Rising damp occurs when groundwater rises through walls via capillary action, often due to a failed or absent DPC. Our treatment involves injecting a modern silane-based damp proofing cream or fluid into drilled holes along the base of the wall, creating a hydrophobic barrier that prevents moisture ascent. This method is highly effective for brick, stone, or rubble walls, with creams like those offering superior penetration and longevity of up to 50 years. We also include re-plastering with salt-resistant renders to remove contaminated materials, ensuring a complete cure with minimal disruption.
Penetrating Damp Treatment
Penetrating damp results from water ingress through walls, roofs, or windows, often exacerbated by poor external rendering or pointing. We apply water-repellent treatments such as silicone-based facade creams or breathable coatings to exterior surfaces, which allow vapour to escape while blocking rain penetration. For severe cases, we repair or replace defective pointing, install cavity wall membranes, or use advanced tanking systems internally to redirect water away from living spaces, providing durable protection and preventing mold growth.
Condensation Treatment
Condensation arises from excess indoor humidity meeting cold surfaces, leading to mould and damp patches. Our solutions include installing positive input ventilation (PIV) systems or extractor fans to improve airflow, alongside thermal insulation upgrades like wall linings or underfloor heating to raise surface temperatures. We also offer mould-resistant paints and dehumidifiers for immediate relief, focusing on energy-efficient methods that reduce humidity levels and enhance overall home comfort without major structural changes.
Basement Tanking and Waterproofing
For below-ground areas prone to water ingress, we provide full tanking services using cementitious slurries or cavity drain membranes that create a waterproof barrier. This involves applying multi-layer coatings or installing dimpled membranes with drainage channels to manage water flow into sumps or pumps. Ideal for converting damp basements into usable spaces, this technique ensures long-term dryness and complies with BS 8102 standards for structural waterproofing.
Damp Proof Membranes and Ventilation Systems
We install high-performance damp proof membranes (DPMs) for floors and walls, often combined with wall base ventilation techniques—either natural or hygro-regulated mechanical systems—to evaporate moisture at the source, particularly in historic or listed buildings. This breathable approach preserves the property’s fabric while effectively treating rising or penetrating damp, with options like magnetic DPC systems for non-invasive, eco-friendly results that improve breathability and prevent salt efflorescence.

Why You Should Get a Damp Proofing Course for Your Home
Investing in a damp proofing course (DPC) is essential for safeguarding your home against moisture-related damage, which can lead to costly repairs if left untreated. A properly installed DPC, whether through chemical injection or physical barriers, creates an impermeable layer that blocks rising damp, preventing structural weakening of walls, timber rot, and plaster deterioration. Benefits include improved health and wellbeing by reducing mould and allergens that exacerbate respiratory issues; enhanced energy efficiency as dry walls retain heat better, potentially lowering heating bills by up to 20%; increased property value through a damp-free environment that appeals to buyers; and long-term savings by avoiding emergency fixes. In regions like Merseyside, where high groundwater and rainfall are common, a DPC ensures your home remains durable, comfortable, and protected for decades.

Damp Proofing Liverpool FAQ
What are the signs of damp in my home?
Common indicators include tide marks or salt deposits on walls up to 1 metre high (rising damp), patchy damp spots higher up (penetrating damp), black mould or condensation on windows/walls, musty smells, peeling wallpaper, or warped timber. If you spot these, book a free survey for professional assessment.
What causes rising damp and how is it treated?
Rising damp is caused by groundwater traveling up through porous walls due to a faulty or missing damp proofing. Treatment typically involves injecting a chemical cream to form a new barrier, followed by re-plastering. This method is effective, non-invasive, and can last 40–50 years with proper installation.
How much does damp proofing cost?
*** All prices mentioned are for guideline purposes and your actual quote may be less or more.
How long does damp treatment take?
Most treatments, like DPC injections, take 1–3 days, with re-plastering adding another week for drying. Larger projects like basement tanking may span 1–2 weeks. We schedule to minimise inconvenience and provide timelines upfront.
Is damp treatment disruptive to my home?
We aim for minimal disruption, DPC injections involve drilling small holes that are filled discreetly, and we protect floors/furnishings. For internal work, we phase it room by room where possible.
Do I need to move out during damp treatment?
Usually not for localised treatments, but for extensive whole-housework, it may be advisable for comfort. We’ll discuss options during your consultation.
Can damp treatment improve my home's energy efficiency?
Yes, by eliminating moisture, treatments reduce heat loss through walls and added insulation, or ventilation can lower energy bills while preventing condensation.
How do I prevent damp from returning?
Maintain good ventilation, fix leaks promptly, ensure external ground levels are below the DPC, and clear gutters. We offer maintenance plans and advice post-treatment.
Are your damp treatments suitable for historic buildings?
Absolutely, we use breathable, conservation-friendly methods like wall base ventilation or magnetic DPC systems to preserve heritage features while effectively treating damp.
