FAQ

Waterproofing in Beirut — FAQ

Pricing, scope, and availability — everything Beirut residents ask about our waterproofing services.

How do I know if my damp wall is a waterproofing failure?

Key signs: damp appears or worsens after heavy rain, there’s a corresponding terrace, bathroom, or flat roof above the affected area, or you can see water staining tracking down from a specific point. We identify the source before treating the symptom — applying waterproofing without finding the source is one of the most common and expensive mistakes in Beirut apartments.

How much does waterproofing cost in Beirut?

Costs range from $200–$600 for a balcony waterproofing repair to $1,500–$5,000 for a full rooftop terrace waterproofing. Our $20 inspection identifies the source and scope, and you receive a written quote before any work begins.

Do you remove tiles for balcony waterproofing?

Only when necessary. If the balcony waterproofing has fully failed, tiles need to come up so the membrane can be applied to the structural slab. We always quote both the tile-removal and tile-replacement costs as separate line items so you see the full picture.

Can damp walls be repaired without opening the ceiling above?

Sometimes — if the water source is a leaking window frame or a hairline crack in the external wall, we can treat it without demolition. If the source is a failed waterproofing membrane in the floor above or a burst pipe inside the slab, some opening is unavoidable. We always try the least invasive approach first.

What is the best waterproofing system for Beirut rooftops?

For flat roof terraces in Beirut, we use torch-applied bituminous membranes for exposed surfaces and liquid polyurethane membranes for areas that will be tiled or walked on. The right system depends on whether the terrace is accessible, whether tiles are going back over it, and the condition of the existing surface.

Why does my apartment get damp every winter in Beirut?

The most common causes in Beirut buildings: failed window frame silicone (water tracks behind the frame into the wall), failed roof or terrace waterproofing above, cracked external render, or blocked gutters and downpipes overflowing against the facade. We trace the actual water path rather than just treating the surface damage.
