Dampness treatment and waterproofing for roofs, walls, and bathrooms.

Water finds its way in through roofs, exterior walls, and bathroom floors, and it's almost always cheaper to waterproof properly than to keep repainting over the same damp patch. We identify where the water is actually entering, not just where the stain shows up.
Work includes roof and terrace waterproofing membranes, exterior wall treatment, and bathroom or balcony waterproofing before tiling. For older buildings especially, this is often the fix that finally makes a recurring damp problem go away for good.
