Disinfection in Harat Al Bahr, Jeddah

Why they keep coming back in Harat Al Bahr

Old buildings here leak constantly through roofs and walls, and sea salt deposits continuously on both external and internal surfaces where the salt air reaches. The method is set out in full on our Disinfection service.

The first reason

Ancient coral stone and sea salt

Coral stone absorbs salt from the sea air and moisture, creating a harsh environment that accelerates material breakdown. We use a specialist disinfectant that does not react with salt deposits or weaken the stone fabric itself.

The second reason

Groundwater moisture and seepage

The quarter sits at low ground level and moisture rises from beneath the foundations continuously. Standard disinfectant does not persist if dampness keeps rising, so we treat the base of walls with a moisture-blocking solution before general disinfection.

The third reason

Deep pores in old coral stone

Ancient coral stone is highly porous and organic matter hides deep inside the rock itself. We use a penetrating disinfectant and leave it for extended periods so it reaches into the pores where eyes cannot see and where bacteria shelter.

The character of Harat Al Bahr

Historic district: close-set buildings, narrow lanes and ageing services

The ancient construction here means that stone, mortar and metal have weathered the sea environment for generations, so we use a disinfectant that does not accelerate corrosion or leave chemical marks on the heritage surface.

Before treatment

What we look at before the product is chosen

The south western part overlooking the sea behind Bab Al Bunt, with old coral stone houses close to the harbour and low ground at the edge of the waterfront where water naturally collects.

The touch points

Stone surfaces and metal fixtures close to the sea accumulate salt and corrosion, so we clean them carefully first before applying a stone-safe disinfectant.

Porous surfaces

Porous stone walls retain moisture for long periods, so we allow the disinfectant to dry naturally without forced ventilation so it can penetrate deeply into the masonry.

The finish itself

Old stone surfaces need a gentle disinfectant that kills pathogens without weakening the stone or leaving white deposits when dry.

The air conditioning unit

Air conditioning outlets in old buildings may be blocked by salt buildup, so we treat them with a mild acid solution first, then disinfectant.

Floor traps

Floor traps in old bathrooms and kitchens often collect stagnant contaminated water, so we treat them with a special solution that reaches deep into the pipe.

Shared entrances and stairs

Cracks and gaps in old stone are hiding places for contamination, so we spray disinfectant at low pressure to reach inside without damaging the ancient material.

How we work

1
Walk the space and list the surfaces

We go through the rooms and mark the touch points, the porous surfaces and the finishes, then ask what prompted the call: illness at home, moving into a new place, building work, or a smell that arrived out of nowhere.
2
Clean what we are about to treat

We take the film of dust and grease off the surfaces that are in scope, so the product reaches the surface itself. This is preparation for the treatment, not general house cleaning.
3
Apply it, and hold the contact time

Hand work on the touch points, a product matched to each surface, and the surface left visibly wet for as long as that material needs before it is dried off. Cold fogging comes last, for what a cloth cannot reach.
4
Ventilate and hand back

We open the place up, rinse food preparation surfaces with water, and tell you when each room goes back into use. We give you that timing on the call, because it changes with the product and the space.

What a disinfection visit includes

A surface and touch point survey

What gets treated, and with what, settled before anything is opened.
Soil off first, then the disinfectant

The greasy film comes off first, then a product that stays wet for the contact time it needs.
Floor traps and the air conditioning drain

Floor traps, sink outlets and the drain tray, which is where most smells actually begin.
Cold fogging for the space

For upward faces and corners a cloth never reaches, done as the last thing before we leave a room.
Ventilation and use instructions

What gets rinsed with water, what is left alone, and when each room goes back into use.
A scheduled repeat when it is needed

For shared entrances and places people pass through every day, because a disinfectant leaves nothing behind to stop the next contact.

Questions about this district

Does white salt on old building walls stop the disinfectant from working?

Yes, salt forms a barrier. We wash walls first with mild salt water to remove excess deposits, then apply disinfectant so it can penetrate the stone underneath.

Does moisture rising from the ground return immediately after disinfection?

Yes, groundwater rises continuously and brings contamination with it. We recommend treating the base of walls with a moisture barrier before disinfection begins.

Do old coral stone houses need a different disinfectant than modern buildings?

Yes, we use a gentler formula that does not weaken the stone or leave white stains on the surface after it dries.

How many times yearly should Harat Al Bahr be disinfected due to the moisture?

We do not recommend a fixed schedule. Instead we assess each house based on actual seepage and moisture levels found during a visit.

Does disinfection include treating cracks and gaps in the old stone?

Yes, we spray disinfectant at light pressure into cracks and gaps so it reaches deep inside, then gently brush the surface to ensure complete coverage.

Does sea air recontaminate the house hours after disinfection finishes?

The sea is a continuous source of new particles, but disinfection kills the living organisms already present. New contamination from the air is far less dangerous than accumulated, aged contamination.

How much does disinfection in Harat Al Bahr cost?

It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Harat Al Bahr.
