Wall damp treatment in Riyadh: before summer & rain season
In short: In Riyadh (Riyadh), wall damp treatment (before summer & rain season) begins with the moisture meter for ceilings and walls and the thermal camera; nothing is opened until the position is clear. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.

Why does a wall that looks dry inside still feel damp, and is it worth treating before the summer heat or the rain arrives? Riyadh is a dry city, but the centre sits about 637 m above sea level, and damp can still rise through old masonry, basement walls and bathroom partitions. Waterproofing cost depends on the surface and the problem. Basement waterproofing typically runs SAR 55–160 per m², bathroom waterproofing SAR 15–40 per m², and crack injection SAR 40–125 per metre. Choosing the right method starts with finding out where the moisture actually enters.
A visit usually begins with a walk around the property to identify the damp areas, marking where stains, peeling paint or powdery patches appear. The inspector then checks the source: whether the water comes from the ground behind a basement wall, from a bathroom floor, from a roof surface, or from a crack that lets rain through. Where a crack is involved, its length is measured in metres so that crack injection can be priced accurately. For larger areas, the surface is measured in square metres, which is how most options are quoted, such as epoxy coating at SAR 35–95 per m² or bitumen membrane at SAR 15–35 per m². The inspector then recommends a method that matches the finding rather than applying one solution everywhere.
Before the visit, gather a few things that make the assessment faster and more accurate. Note where you have seen damp, and when it appears, for example after rain or during the cooler months. Clear the walls as far as practical so the inspector can reach them, and move stored items away from the affected areas. If the property has a water tank, mention it, since tank internal coating is priced separately at SAR 25–65 per m². Photos of the stains and any earlier repairs are also helpful. With these details ready, you will get a clearer picture of the work needed and its likely cost before the summer or rain season begins.
Checks before summer and before the rain season catch problems while they are still small.

Tools and methods, and when we use them
| Method | What it helps with | Its role in Riyadh |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
From the first visit to the report
- Moisture readings: Readings are taken in a grid across the wall.
- Finding the cause: Pipe, condensation or rising damp.
- Treatment: The cause is treated before the finish.
- Finishing: Plaster and paint after the wall has dried.

Short answers for Riyadh
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.
What is the first step of wall damp treatment (before summer & rain season)?
We start with moisture readings (readings are taken in a grid across the wall), then finding the cause (pipe, condensation or rising damp).
How much does wall damp treatment cost in Riyadh?
From our published price list: Inspection visit SAR 150 per visit. Quantities are confirmed at the inspection.
What do I get at the end?
The cause and the proposed treatment, in a technical report that carries a verification code.
What we advise against

Practical notes for residents of Riyadh
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
