Disinfection in Harat Al Yaman, Jeddah

Why they keep coming back in Harat Al Yaman

In the narrow alleys, disinfectant vapour pools rapidly and does not disperse, so we need slightly longer contact time to ensure the product works at full strength. The method is set out in full on how we approach Disinfection.

The first reason

Porous coral stone dries the product too quickly

Centuries old coral stone is highly porous and drinks water and disinfectant faster than modern paint does. The product dries before it completes its full working time, reducing effectiveness and requiring adjustments to contact duration.

The second reason

Popular souqs introduce competing contamination daily

Daily foot traffic, vendors and customers bring diverse contamination into the quarter. Disinfection must pay particular attention to high touch points inside shops and exposed surfaces facing public areas.

The third reason

Limited air flow means moisture lingers and contaminates again

Narrow lanes between tightly packed houses severely restrict air circulation. Residual moisture after disinfection can cause returning odour or mould growth if complete drying is not achieved in these confined spaces.

Before treatment

What we look at before the product is chosen

Closely packed stone houses and popular markets keep the air humid and restrict natural ventilation, which directly affects how quickly the disinfectant dries and how well it works.

The touch points

Narrow alleys restrict natural air movement, so we open windows longer and may run fans to speed drying once the disinfectant has completed its work cycle.

Porous surfaces

Centuries old coral stone is far more porous than modern finishes and holds disinfectant moisture considerably longer, which helps effectiveness but means final humidity levels may run higher than expected.

The finish itself

Old paint on historic stone may already be peeling or flaking, and disinfectant penetrating beneath it can accelerate further loss if the paint layer is already weakened.

The air conditioning unit

Traditional wind catchers or old air conditioning units may draw humidity and outside contaminants inward, so we focus on cleaning openings and drainage pathways carefully.

Floor traps

Floor traps in old houses may drain slowly or be partially blocked, leaving accumulated waste where the disinfectant cannot reach all the contamination present.

Shared entrances and stairs

Shared stairs and passages are narrow and often dark, with moisture and mould collecting rapidly there. These spaces receive our closest attention during disinfection work.

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.

The character of Harat Al Yaman

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

Ancient stone structures need protection from excess moisture that can hasten cracking and paint loss. We select disinfectants that balance effectiveness against safety for the fabric itself.

Questions about this district

Does the disinfectant damage the old coral stone structure?

We use disinfectants safe on historic coral stone, but avoid prolonged soaking or excess water since ancient stone is fragile. We dry surfaces thoroughly after the working period to protect the material.

The ground floor flat sits under a popular souq. Humidity is extremely high. Will disinfection work?

Moisture from the souq, foot traffic and heavy water use raises overall humidity significantly. We treat porous surfaces carefully to avoid increasing moisture further while ensuring the product still reaches the contaminated surfaces.

How often should an old stone house in the quarter need disinfection yearly?

Frequency depends on household size, occupancy level and proximity to the busy souq. Homes directly adjacent to markets need more frequent treatment than those in quieter alleyways.

Does disinfection reach cracked or crumbling stone surfaces safely?

Yes, cracks and fissures can harbour germs and contaminants. We ensure the disinfectant penetrates but apply it gently to prevent causing additional damage to already compromised stone.

Right after disinfection the old stone smell is very strong. Is that normal?

Yes, the disinfectant cleans the surface and reveals the natural stone itself. The odour is temporary and fades once the space is properly ventilated.

Does disinfecting an old stone house protect it from insects drifting in from souqs?

Disinfection kills germs and contaminants but stopping insects requires sealing cracks and windows and working with a pest controller if the problem persists.

How much does disinfection in Harat Al Yaman 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 Yaman.
