Raghwat Al Janoub Maintenance and Cleaning

Building facade cleaning in Dumat Al-Jandal

Dumat Al-Jandal is a historic oasis town south west of Sakaka on rocky ground at moderate altitude. The old Al-Dar'i quarter keeps stone houses around Marid Castle and the Omar Mosque, while the modern town spreads villas among palm groves and farms. Summers are hot and dry, winters cold with possible frost at night. Spring dust blows up from the south, and winter rain falls scattered and unpredictable.

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 Dumat Al-Jandal

Dust here is a mix of Nafud sand and local quarry dust, leaving an orange-red tint on stone that is stubborn to remove from old walls. The whole method is set out in the building facade cleaning overview.

  • Old stone and historic structures

    The Al-Dar'i quarter keeps stone houses from centuries past, and the stone is porous and fragile, easily damaged by harsh cleaners. Marid Castle and the Omar Mosque are close by, meaning neighbouring buildings may be old and need special care.

  • Coloured spring dust from the Nafud

    Spring winds carry fine Nafud sand with an orange-red tint. Dust settles deep in stone and cladding pores, leaving a strong colour that plain washing does not lift.

  • Winter cold and night frost

    Winters in Dumat Al-Jandal are very cold with temperatures dropping to freezing. Frost makes water freeze quickly on surfaces, and harsh products may damage stone that expands and contracts in cold.

What's Included

The town sits on rocky terrain at moderate height in the Al-Jouf region. Summers are dry and hot, winters cold with temperatures falling below freezing at night.

  • Roof survey and anchor points

    Roof survey reveals stone and concrete condition and confirms anchor point strength. Rocky ground may offer different fixing points, and we test each one carefully.

  • Access chosen: rope or powered

    Rope access suits both old and modern buildings here. Powered platforms may be difficult on rocky terrain.

  • A test patch before the whole elevation

    Testing a small stone patch before treating the whole wall is always essential.

  • Glass and curtain walling

    Glass is cleaned with lukewarm water and soft brush, and salt deposits may leave residue needing several rinses.

  • Cladding and stone, pH-neutral

    Stone and cladding are washed with very gentle pH-neutral products, and old buildings need extra care.

  • Ground and passers-by protected

    Rocky ground needs protection from water drainage, and water may freeze at night.

Landmarks of Dumat Al-Jandal

Marid Castle and the Omar ibn Al-Khattab Mosque sit in the Al-Dar'i quarter, and around Dumat Al-Jandal lake and its market the old and modern buildings spread. Access to sites sometimes passes through the narrow lanes of the historic quarter, so planning respects street width and landmark sensitivity.

What is different about Al Jouf Region

Al Jouf is the olive growing north, with Sakaka, Dumat Al Jandal, Qurayyat and Tabarjal set among groves and farms on a plateau above the Nafud sands. The towns are low rise villas, wide streets and farm warehouses, and Dumat Al Jandal keeps stone houses and the Marid castle from earlier times. Winters are cold with frost, fog and rain, summers dry and bright, and spring dust blows up from the south. Rain on dusty render leaves streaks, damp mornings hold grime on glass, and the olive harvest season adds a fine oily dust of its own.

Questions before booking

Can old stone in Al-Dar'i quarter tolerate water and brush washing?
Yes but with great care. The stone is old, porous and may be harmed by hot water. We use lukewarm water and a very soft brush, and testing a small area first is essential.

Does the orange-red dust tint leave permanent marks on stone?
Not if cleaned soon after. Dust settles deep but regular cleaning removes it. Left for weeks it may need a slightly firmer brush.

Can we clean facades during cold winters?
Yes but we choose relatively warm daylight hours. Night frost makes water freeze, so we avoid night and early dawn.

Does Marid Castle and the old mosque nearby mean the stone is sensitive?
The stone may be sensitive if close to these historic landmarks. It may be from the same period, so we clean it with very gentle approved products.

Does hard groundwater in Dumat Al-Jandal affect cleaning results?
Yes, the water is hard and leaves salt deposits on stone. We use treated water for the final rinse.

How often per year should the old stone in Al-Dar'i be cleaned?
Two or three times: once after spring dust season, once before winter if new dust has built up. Frequent gentle cleaning is better than harsh infrequent cleaning.

How much does building facade cleaning in Dumat Al-Jandal 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 Dumat Al-Jandal.
