Laqeeni guide · Riyadh

Before you hire a water tank cleaning company in Riyadh

Discoloured water, a smell, or sand in the taps? Before you call anyone, read this: safe checks you can do from inside the home, signs your tank needs cleaning or insulating, and the questions that protect your water.

Safe checks before you call anyone

All from inside the home. Don't climb onto the tank or into it, and don't open an underground tank yourself. That's the company's job.

Water colour

Fill a clear glass from the tap and look at it in the light. Yellow or cloudy? Take a photo.

Water smell

Smell the cold water from more than one tap. If every tap smells, it's probably the tank.

Tap filters

Unscrew the small filter at the end of the tap, check for sand or grit, and rinse it.

When was it last cleaned?

If it's been more than 6 months, or you don't know, it's probably time.

🚫 Never climb onto or into a water tank yourself. Cleaning and insulating are for the company.

Signs your tank needs cleaning or insulation

And what usually causes them. Only the company can say for sure, but this helps you understand what they tell you.

Yellow or cloudy water

Usually sediment or rust at the bottom of the tank. Cleaning removes it; if it comes back quickly, the pipes may be the problem.

A strange smell in the water

Usually algae or bacteria in the tank, or a lid that doesn't close properly. It needs cleaning and disinfecting.

Sand or grit in the taps

Sediment in the tank or from the water truck. Clean the tap filters, and have the company clean the tank.

The underground tank level drops

A sign of a leak or cracks in the tank. It needs checking and insulating before it affects the foundations.

Roof tank water very hot in summer

The tank is in direct sun. A shade or heat insulation makes a big difference.

Insects or green algae

Usually the lid is open or broken. Ask the company to replace the lid, then clean and disinfect the tank.

Roof tank, underground tank or insulation: what's different

The type of tank and the job change the time and the price.

Roof tank

On the roof, and usually smaller.

  • Cleaning is usually easier and cheaper.
  • If the water gets very hot in summer, ask about a shade or heat insulation.
  • Make sure the lid is tight.

Underground tank

Below ground, and usually bigger.

  • Usually costs more than a roof tank of the same size, because it's harder to reach and empty.
  • Keep some drinking water aside before cleaning.
  • Ask for before-and-after photos from inside.

Tank insulation

If the tank loses water or has cracks.

  • Ask whether the material is suitable for drinking-water tanks.
  • Ask to see the tin.
  • Get a written guarantee with the number of years.

When to clean, and keeping the water safe

Every 6 months

Cleaning the tank once or twice a year protects your family, and the pump, heater and pipes.

A tight lid

Ask the company to make sure the lid is closed and sealed so no dust or insects get in.

Watch the water truck

Order water from a known source, and check the truck looks clean before it fills your tank.

Clean the filters

After the tank is cleaned, clean the tap and shower filters too: they hold old sediment.

Questions to ask a tank cleaning company

Ask before any work starts. A good company won't mind.

  1. What does the price include?

    Emptying, cleaning, disinfecting, rinsing and refilling? Ask about each step, not just "cleaning".

  2. What do you disinfect with?

    Ask which product, and make sure they rinse the tank well afterwards so no taste or smell is left.

  3. Is the insulation safe for drinking water?

    If you're insulating, ask about the material and ask to see the tin.

  4. What guarantee do I get?

    Especially for insulation: how many years? Get it in writing, even on WhatsApp.

  5. Can I see before and after?

    Ask for before-and-after photos from inside the tank before it's refilled.

  6. Can I see photos of past jobs?

    Look at photos of past work and genuine reviews from earlier customers.

Warning signs

One sign on its own doesn't prove anything, but take care if you see them.

"Cleaning" with no disinfecting or rinsing

Ask about each step. Cleaning without disinfecting and rinsing isn't enough.

Won't show you the insulation material

Or doesn't know if it's safe for drinking water. Think twice.

No photos from inside the tank

You can't be sure the work was done.

Insulation with no written guarantee

Insulation is expensive work. Get the guarantee in writing before they start.

Rough guide

Rough prices (a guide only)

Rough prices for homes. Use them to spot a quote that's way off, not as fixed prices. The final price depends on the tank size, how much sediment there is and how easy it is to reach.

ServiceRough price
Small roof tank (under 5 m³)SAR 150 – 250
Medium tank (5 – 15 m³)SAR 250 – 400
Underground tankSAR 300 – 700
Underground tank insulation (cracks treated, insulation layers)SAR 700 – 1,250
Polyurethane tank insulationSAR 1,200 – 1,500

💡 More than one tank? Clean them in the same visit. Some companies give a discount on the second and third tank.

🔧 An underground tank usually costs more than a roof tank of the same size, because it's harder to reach and empty.

Common questions

How long does tank cleaning take?

A normal home tank usually takes two to four hours; a large underground tank takes longer. Keep some drinking water aside first.

Do I need to insulate my tank?

If your underground tank loses water or has cracks, insulation stops the leak and protects the water. If there's no problem, regular cleaning is enough.

Does Laqeeni take commission?

No. Laqeeni is a directory that connects you with the company directly. You agree and pay between you.
