Post-construction cleaning in Al Sinaiyah Al Qadimah, Riyadh

Al Sinaiyah Al Qadimah is an established industrial quarter in east-central Riyadh, with repair and metalworking shops, storage warehouses and a small amount of attached housing. Wide straight streets for trucks, and metal and oil dust settles heavily on every concrete surface and floor.

Why this is not routine cleaning

  • Build residue needs more than wiping

    Cement haze and silicone lines need a scraper and the right chemical for each surface, not a cloth.

  • The right order, top to bottom

    We start at the ceiling and high vents and work down to the floor, dry before wet.

  • Glass and marble handled with care

    Riyadh's mineral dust and the region's hard water leave calcium scale on glass that scratches if you scrub hard or leave it too long.

  • Vents cleared before first use

    Building dust drifts into AC outlets and vents and lodges in the filters, so the first time the unit runs it blows that dust through every room.

Why the job is different in Al Sinaiyah Al Qadimah

Raw concrete floors in the shops collect deposits of oils and metals that sink deep into the pores, and this is not like ordinary construction dust and needs completely different treatment. The whole method is set out in the details of our post-construction cleaning service.

  • Raw concrete absorbs oils and grease down to depth

    Workshops are left on bare concrete with no paint or sealer. Oils from equipment and trucks sink into the deep pores of the concrete. Stripping these oily deposits from workshop concrete needs strong specialised solvents and very large volumes of water to rinse clean, or surfaces stay slick and odourous.

  • Iron and aluminium corrode and oxidise fast here

    Iron doors, windows and aluminium in old shops collect moisture and oxide quickly. Metal dust leaves black or red coating on iron and aluminium depending on alloy. Stripping rust and oxide needs precise chemical handling and protection against new oxidising, because the environment is hostile.

  • Heavy daily trucks leave deep oily marks on street

    Heavy trucks and machinery daily shed oil and grease onto the concrete streets. These marks will not lift with plain water and need strong solvents. Old concrete is more porous and oils bite deeper than in new concrete, making removal harder and slower.

What's Included

An old industrial quarter with wide straight streets built for heavy truck movement, holding workshop plots, storage warehouses and car repair and metalworking shops, with only a small number of flats and homes attached to the workshops.

  • Construction debris removed

    Metal and oil and grease debris leaves deep deposits on raw concrete, and clearing these from industrial floors needs specialised industrial techniques unlike any home method.

  • Cement haze removed

    Metal and iron dust builds thick on surfaces and iron, and the wide streets let more truck dust enter from all directions.

  • Stickers and protective film stripped

    Stickers on industrial iron and aluminium must be cleared before rust starts, especially on old doors and windows exposed to weather.

  • Paint spots and silicone smears

    Oil and grease spots on concrete and oxide marks on iron need specialised chemical treatment without damaging the metals themselves.

  • Vents and outlets de-dusted

    Industrial vents and openings are blocked with heavy metal particulate and oils before any ventilation or mechanical systems can run.

  • Final polish of the surfaces

    Concrete needs complete drying and final polish after rinsing, and iron and aluminium are re-polished after rust and oxide treatment.

The character of Al Sinaiyah Al Qadimah

Industrial area: workshops, warehouses and loading yards

An old industrial zone means surfaces have absorbed oils deep over years. Concrete, iron and aluminium need harsh treatment unlike housing, and long-term protection against new oxidising after cleaning.

Questions before booking

Is workshop cleaning different from the flats above it?
Completely different. Workshop floors are raw concrete that absorbs oils and metals into the deep pores. Flat floors are different entirely. Shops need strong solvents, flats need routine cleaning agents. Each needs a separate team and completely different tools and methods.

How do you clear deep oil from workshop concrete?
Oils sink concrete depth. We use specialised oil and grease solvents that react with deposits in the pores. Then very large volumes of water rinse, and the floor dries completely before handover. Without complete rinsing the surface stays greasy and slippery.

Do old iron doors in the shops need rust protection?
Yes heavily. Iron in the old industrial zone corrodes fast. After stripping existing oxide, we seal against new rust. Without this coating, rust returns within weeks because moisture and metal dust are constant.

Does metal dust leave a permanent colour on surfaces?
Metal dust leaves black or red coating depending on alloy type. The colour bonds to surfaces and glass and will not lift with plain water. It needs specialised solvents or gentle friction with very fine abrasive compounds.

Are old workshops harder to clean than new ones?
Yes, old concrete is more porous and oils penetrate easier and deeper. Aged floors take longer because the oils are deep. New workshop concrete is harder and less absorbent so oils do not bite as deep.

How long does it take to clean a shop unit and flat above together?
If the shop is a workshop or retail unit on concrete and the flat above is different flooring, both need completely separate treatment. One crew works the shop with strong solvents, the other the flat with gentle agents. Total time is two to three days depending on size.
