Business Overview
WP Ltd is a family run team of waterproofing contractors based in Qormi, serving homes and businesses across Malta and Gozo. Founded in 1988 and now a third generation family business, WP Ltd has spent decades solving damp proofing and water penetration problems that quick fixes fail to cure. Every job starts with a proper inspection, not a guess, because lasting waterproofing depends on finding the real source of the leak before any membrane goes down. That grounding in real experience is what property owners are really paying for when they call in waterproofing contractors rather than reaching for a tin of sealant themselves.
Roof waterproofing sits at the centre of what the team does. Malta's summers bake flat roofs under strong sun while winter storms test every joint and upstand, and appoggi, terraces and roof gardens all take a battering over the years. WP Ltd applies bituminous membrane and liquid Read Moremembrane systems depending on the roof type, and the same expertise extends to landscaped roof gardens, where root barriers and membranes are laid beneath planting so moisture never reaches the slab below. Where an existing roof has cracked or split, the team carries out waterproofing repairs rather than a full replacement wherever that is the more sensible and affordable option for the client.
Balcony waterproofing is another area where quick, reliable work matters. Balconies flex with temperature changes and take rain from every angle, and once a slab cracks, water tends to travel and reappear as a stain on the ceiling of the room below. WP Ltd inspects the full balcony before recommending a treatment, then applies a sealed finish designed to keep water out for years rather than months. Wall waterproofing follows the same logic, whether the wall in question is an exterior surface facing driving rain or an internal wall in a kitchen, bathroom or basement where humidity builds up unnoticed until it becomes a visible problem.
Basement waterproofing calls for a different approach again, because below ground structures face constant pressure from groundwater and soil moisture rather than occasional rain. WP Ltd treats basements, lift pits, wells and underground storage areas with systems built for that below grade environment, so foundations, floors and joints stay dry whether the building is newly constructed or already showing signs of water getting in. The same structural mindset applies to canopies and other exposed features that are easy to overlook until a leak appears somewhere inside.
Damp proofing is one of the most requested services the company handles, and for good reason. Damp is common in older Maltese properties where the original waterproofing has broken down over the decades, and it rarely stays a cosmetic issue for long. Left untreated, it causes plaster to crumble, paint to bubble and mould to take hold, which can affect the health of anyone living or working in the property. WP Ltd traces the moisture back to its source before starting any repair, because a damp patch painted over without fixing the underlying cause will simply return within a season. Where earlier waterproofing repairs have failed, the team reassesses the problem from scratch rather than repeating the same fix.
What sets WP Ltd apart is the combination of genuine hands on experience with materials that are globally certified for durability. Installations carried out by the team come with a ten year guarantee as standard, and certain higher specification products extend that cover to twenty years. In some cases, older installations have been renewed and found still performing after thirty years of service, which says as much about the quality of the original work as it does about the materials used. As a family run business now into its next generation, WP Ltd treats every job, large or small, with the same level of care and the same attention to detail that has carried the company for decades.
Beyond membrane waterproofing, the team also offers insulation solutions that help regulate indoor temperatures through Malta's hot summers and humid winters, cutting energy costs while keeping moisture and mould at bay. For property owners looking to go a step further, WP Ltd can integrate solar photovoltaic technology directly over a waterproofed roof, turning a protective membrane into a source of clean energy without the need for a separate installation. It is a practical way to get more value from a roof that already needs protecting.
Choosing the right waterproofing contractors also means knowing that someone will stand behind the work long after the van has driven away. WP Ltd's guarantees, the certified materials used on every job, and the decades of hands on experience behind each decision all exist for that reason. Clients are not just buying a membrane. They are buying the judgement to know which membrane suits their roof, their balcony or their basement, and the workmanship to install it correctly the first time.
Whether the problem is a leaking roof, a cracked balcony, a persistently damp wall or water finding its way into a basement, WP Ltd has the experience and the materials to solve it properly the first time. Free quotes and site inspections are available for every enquiry, and the team works around each client's schedule to keep disruption to a minimum.
