Floor & balcony waterproofing in Jeddah: when to call a technician
In short: In Jeddah (Jeddah), floor & balcony waterproofing (when to call a technician) begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. Jeddah is about 2 km from the sea coast (OpenStreetMap). Pricing starts from Bathroom waterproofing (per m²) (SAR 15–40 per m²), and other items are quoted after the visit.

Jeddah sits on the Red Sea coast, with the city centre about 15 m above sea level, and the sea itself is roughly 2 km from the coast line. That combination of a low, coastal position and warm, humid air means that salt-laden moisture and rain runoff gather on floors and balconies rather than draining away quickly. For homeowners, the practical effect is that water tends to find its way through hairline cracks and drainage gaps sooner than it would inland, so checking your balcony and floor surfaces once a year is a sensible habit rather than a rare event.
Because the ground level is close to the sea, the choice of waterproofing system matters as much as the timing. Crack injection is priced at SAR 40–125 per metre and is often the right first step when a leak is traced to a specific line, while epoxy coating at SAR 35–95 per m² suits walkways and floors that see foot traffic. Liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² are commonly used on open balconies and roofs, where sun and rain are the main stresses. A technician who visits the site can match the material to the surface, rather than applying one product everywhere.
Owners in this area often avoid several common mistakes. They do not wait for a stain on the ceiling below before calling anyone, since moisture is usually moving through the structure for some time first. They avoid painting over a damp surface, which traps water and causes the coating to lift. They also do not compare quotes only on price, because a low per-m² rate means little if the surface was not cleaned, cracks were not sealed first, or drainage outlets were left blocked. Calling a technician at the first sign of dampness, before the damage spreads, is the simplest way to keep repair costs in check.
Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
Signs worth paying attention to
The following signs are worth checking before they grow:
- A wrong fall towards the door threshold
- Water passing from the balcony to the floor below
- Damp under the light well
Where the problem usually comes from
- Incorrect falls.
- A threshold without waterproofing — we check this before anything else.
- A common cause: a blocked drain.
How we choose the tool in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
From the first visit to the report
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

Questions from Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
What is the first step of floor & balcony waterproofing (when to call a technician)?
We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
