Raghwat Al Janoub Maintenance and Cleaning

Building facade cleaning in Najran

Najran is a desert provincial capital blending modern apartment blocks and hotels with an old mud quarter near the Al Ukhdood ancient ruins, where palm and citrus groves line a dam fed wadi. Facades here face fine desert dust, very hard groundwater leaving thick lime scale on glass, and mould growing fast on stone and cladding due to moisture from irrigation and the dam.

Why a facade needs regular cleaning

  • The surface is protected

    The wrong product costs more than the dirt it removes.

  • Access decided on site

    We do not pick the access method from an office.

  • Glass stays clear

    Calcium scale on glass turns into permanent etching if it is left.

  • The building keeps running

    We plan the access and the working hours around how the building is used through the day, and we protect the ground, the entrances and anyone passing below.

Why the job is different in Najran

Residential blocks and hotels in the city centre foul quickly from desert dust, whilst old quarters near the ruins and groves hold high moisture and grow algae and mould. The whole method is set out in our notes on building facade cleaning.

  • Oasis and dam location means humidity stays high despite desert setting

    Najran is surrounded by desert but sits on a wadi with dam water that raises humidity noticeably. Groves and palms around the dam evaporate large volumes of water, lifting relative humidity visibly. Buildings in the wadi near the dam face high moisture, whilst those away are relatively dry. This split means the city needs different cleaning plans by distance from the wadi.

  • Groundwater is very hard, leaving thick lime scale difficult to remove

    Groundwater here is very hard, and washing with it leaves white lime scale thick on glass and stone. This scale needs specialist treatment to lift, and etches the surface if left long. We choose different water or use mild acidic treatment to shift scale safely.

  • Mould and algae grow fast on stone and cladding in high wadi humidity

    Moisture from irrigation and the dam creates ideal conditions for mould and algae to grow on stone walls and cladding. Old quarters near the ruins and groves are most exposed, as shade and moisture slow drying. Specialist treatment is needed to lift mould without damaging old stone or cladding.

What's Included

Dry desert surrounding a wadi fed by a dam, with desert soil and very hard groundwater. Humidity is high in the wadi from irrigation and groves, but buildings away from the wadi are bone dry.

  • Roof survey and anchor points

    Roofs around the ruins and dam are varied between old stone and modern blocks, and anchor calculations differ by building type and site.

  • Access chosen: rope or powered

    Access to old quarters can be limited as they were built at high density. Modern villas and blocks are easier to reach.

  • A test patch before the whole elevation

    Testing products on old stone and clay is essential because mould needs gentle treatment that does not damage the surface.

  • Glass and curtain walling

    Glass accumulates both desert dust and mould from moisture, and may need separate treatment by location.

  • Cladding and stone, pH-neutral

    Stone and cladding need mild products that lift mould without stripping or leaving rust marks.

  • Ground and passers-by protected

    Ground and passing residents near buildings are protected by barriers, and run-off water is routed away from groves and paths.

Questions before booking

Does closeness to groves and the dam raise facade humidity noticeably?
Very much so, buildings near the wadi and dam face far higher moisture than the desert. Mould and algae grow faster on these buildings and need frequent cleaning.

Does hard groundwater used in washing leave permanent lime scale marks?
Hard water leaves thick white scale, and if used by mistake in washing scale becomes hard to lift. We use different water or mild acidic treatment safe on stone.

Do old mud brick quarters need special mould care from repeat growth?
Yes very much, clay absorbs moisture deep and mould sprouts fast. We use products safe on clay that do not strip it, removing mould without damaging old surfaces.

Does desert dust cause less trouble here than moisture and mould?
Dust is a problem in desert away from the wadi, but moisture and mould are worse in the wadi and groves. Buildings may need different treatment by location.

Do nearby groves and palms speed up mould growth on facades?
Yes, constant irrigation and palms and shade raise moisture and mould grows fast. Buildings surrounded by groves need more care than those in bare desert.

How often should Najran facades be cleaned through the year?
Buildings near the wadi and dam need frequent cleaning for mould and moisture. Buildings away in the desert may need less but still regular work. A schedule matched to wadi distance works best.

How much does building facade cleaning in Najran cost?
It is set after we have seen the job, because the price follows the height of the building, the type and condition of the facade and the access it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Najran.
