In a duplex, the two floors often share lines, so tests are done floor by floor.
Signs that call for roof tank leak detection
If you notice one of these signs in Alahsa, it is a good moment to talk to the team:
- Water on the roof around the tank base
- A stain on the top-floor ceiling
- Repeated spills from the overflow outlet
Where the problem usually comes from
- A common cause: a fibreglass or polyethylene tank cracking in the sun.
- Inlet and outlet connections — we check this before anything else.
- A worn float valve.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Dye test | Water being drawn in at openings and cracks | Limits: only for visible, nearby points |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
How the work is done, step by step
- Inspecting the base and connections: We look at where water gathers and trace it back.
- Level test: The level is recorded with filling stopped.
- Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
- Recommendation: Repair of the connection, the float or the tank, stated in writing.

Short answers for Alahsa
Is it possible to unclog drains without breaking the floors?
In most cases, yes: camera inspection and high-pressure water jetting clear the blockage from drain openings and inspection chambers without breaking anything, except when there is an actual break in the pipes.
Does renovation include treating dampness and insulation?
Usually yes, since dampness treatment is an essential part of renovation, especially in Al-Ahsa. The contractor identifies the source of the leak and then carries out the appropriate insulation. Mention the dampness problem in your request description.
What is the difference between foam insulation and roll insulation?
Foam is sprayed on as a continuous layer with no seams and provides both thermal and water insulation, while rolls are separate pieces that require joining and mainly focus on water insulation.
