Disinfection in Al Nazlah Al Yamaniyah, Jeddah

Targeted, not broadcast

Product goes into cracks and runways, never sprayed across open surfaces.
Told before we start

What we will use, where it goes, and what to cover or move before we arrive.
A follow-up visit

We return after the first treatment, because what survives it does not show on the day.

Why they keep coming back in Al Nazlah Al Yamaniyah

Lanes are very narrow, blocks are pressed close, humidity is very high and insects live in every corner. Rainwater sits in the narrow streets for days after it falls. The method is set out in full on how we approach Disinfection.

The first reason

High population density and narrow streets trap moisture and odour

Blocks stand very close and lanes are very narrow so air does not move freely. Moisture, mould and odour are trapped in the streets and homes with no escape.

The second reason

Old drainage networks leak and run beneath the narrow lanes

Ancient drainage pipes beneath the lanes leak from everywhere. Moisture and smell rise from beneath, and insects use these routes to travel between homes.

The third reason

Ancient stone foundations and walls wick water and salt upward

Old foundations and stone walls do not block water or salt but instead draw them up from the ground. Walls stay perpetually damp and mould spreads rapidly.

Landmarks of Al Nazlah Al Yamaniyah

Al Nazlah Al Yamaniyah centres on Khuzam Palace, home to the Jeddah Regional Museum, which stands as a witness to the quarter's past. King Khalid Street extends from the palace carrying commercial activity and constant foot traffic, with other lanes radiating from around the palace in a semi-organic pattern.

Before treatment

What we look at before the product is chosen

An overcrowded quarter of old apartment blocks packed close together with traditional houses on very narrow lanes and ageing drainage.

The touch points

Repeated touch points such as doors, switches, railings and shared stairs all sit in constant contact with moisture and mould.

Porous surfaces

Porous surfaces such as old stone walls and aged plaster absorb water and disinfectant readily, so contact time must be long and humidity must be moderate.

The finish itself

Old finishes of plaster, thin paint and traditional ornament are easily damaged by strong disinfectants.

The air conditioning unit

Air conditioning units in old blocks are themselves old and heavily soiled, so we clean and dry them thoroughly before disinfection.

Floor traps

Floor traps and shared drainage in the block are very old and surrounded by moisture, so we treat them intensively.

Shared entrances and stairs

Shared entries, stairs and passages are constantly damp and mould grows rapidly, so we disinfect them regularly and carefully.

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.

What is different about Al Jamiah Sub-Municipality

Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.

Questions about this district

The flat is in an old building and the walls are constantly damp. What is the solution?

Moisture comes from the ground, the narrow street and old drainage. Disinfection treats current mould, but moisture returns. We focus on ventilation and drainage improvement.

A strange smell from the street enters the flat through cracks and windows. How do we stop it?

The smell comes from old drainage and water pooling in the narrow street. We disinfect the flat and seal openings and cracks.

Cockroaches come from the street, the neighbouring flat and below. What is the solution?

Cockroaches use old drainage and numerous cracks as highways. We disinfect the flat, traps and cracks and seal them with an insulating compound.

Should an old apartment block be disinfected as a whole separately from individual flats?

Yes. The whole block is a single environment for insects and moisture. Disinfecting one flat may help temporarily, but insects return from other flats.

Old Hijazi houses sit beside new apartment blocks. How often should we disinfect?

Old houses are more damp and mouldy. We may need more frequent treatment, especially after rain and in winter.

A few days after disinfection, the smell and insects returned. Why does this happen?

Old drainage, numerous cracks and other flats are continuous sources. We may need repeated treatment and crack repair.

How much does disinfection in Al Nazlah Al Yamaniyah 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 Al Nazlah Al Yamaniyah.
