Disinfection in Al Khansa Makkah

Al Khansa is a densely packed district between Al Hajj Street and Al Abtah with old popular houses and modern apartment blocks woven together, the Al Adl cemetery on its edge, and a history of property expropriation for road widening. The high density and tangled old pipes mean disinfection is not an isolated job: contaminants return from neighbours through shared cracks and interconnected drainage that no individual flat can treat alone.

Why they keep coming back in Al Khansa

Flats in the old popular houses suffer recurring odours and bacterial regrowth because the drainage systems are interlinked with neighbouring units in ways that individual treatment cannot address. The method is set out in full on what Disinfection involves.

The first reason

Old houses have tangled pipes shared between neighbours

The older popular buildings in the district were constructed before modern building codes, and the pipes do not run cleanly separated. Drainage from a neighbour's unit can enter your flat through weak joints and small gaps. Disinfecting your flat alone does nothing if the pathways between units are not sealed. Within days, contamination re-enters from next door through the same routes.

The second reason

High density means contaminants travel between homes very quickly

The buildings are pressed close together and cracks and gaps between units are numerous. Air, humidity, insects and bacteria pass between flats with ease. What you treat today may return tomorrow from the neighbour's side, and the only answer is a continuous preventive programme, not a single treatment. Isolation of your flat is nearly impossible in a closely built block.

The third reason

Cracks in old walls provide pathways bacteria use to spread

Historic clay and old plaster walls contain fine deep cracks invisible to the eye but sufficient for bacteria, viruses and insects to travel through. A disinfectant here needs higher concentration and targeted injection into larger fissures. Treatment takes longer than in modern buildings because the pathways are less predictable.

Before treatment

What we look at before the product is chosen

The district lies between Al Hajj Street and Al Abtah close to the Grand Mosque precinct, with Al Maabdah Street linking it to surrounding areas. Its main thoroughfares have undergone repeated development phases over decades.

The touch points

Touch points in a tightly packed flat are exposed to contaminants from neighbours through air and small gaps, and they need more frequent disinfection than detached or loosely spaced homes.

Porous surfaces

Porous surfaces of clay and old plaster walls absorb moisture and smells deeply, requiring higher product concentration and much longer contact time than modern surfaces.

The finish itself

Floors in old buildings are often uneven and have cracks around drain openings, requiring deep cleaning before disinfection can be effective.

The air conditioning unit

Old or shared air conditioning units can transfer contaminants between flats, so careful cleaning of the unit is essential before general disinfection.

Floor traps

Floor drains in old buildings are often shared or positioned very close together, and deep regular treatment is necessary because odours return quickly.

Shared entrances and stairs

Shared stairs and entrances in densely packed old apartment blocks suffer from high humidity and persistent smell, and weekly disinfection works better than monthly cycles.

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.

Landmarks of Al Khansa

The district is positioned between Al Hajj Street, which connects it to shopping and administrative hubs, and Al Maabdah Street, which leads directly towards the Grand Mosque. Entering via either route reveals immediately the high density and tightly built old houses that define the neighbourhood.

Questions about this district

Every time I disinfect the flat, the smell comes back from the neighbour. What should I do?

The odour enters through shared pipes and gaps between flats, so the solution requires co-operation with the neighbour. We recommend disinfecting both flats at the same time, sealing gaps and cracks with engineering sealant, and treating any shared drainage traps if they exist. Treating one flat in isolation has limited lasting effect.

The old house is very damp and the disinfectant dries quickly. Is that normal?

High humidity in old buildings speeds up the drying time of the product and reduces how long it stays wet on the surface. We recommend using fans to dry out the room first, then applying the disinfectant, and keeping ventilation minimal while it works so it does not dry too fast.

Do the small cracks in the old walls need separate treatment?

Yes, fine cracks trap bacteria and fungi deep inside. We clean them first with a soft brush and water, then inject concentrated disinfectant into the larger ones with a small syringe, and allow them to dry slowly. A general surface treatment does not reach inside the cracks.

The old pipes in the building are corroded. Will disinfection improve the smell?

Disinfection kills bacteria temporarily, but corroded pipes provide ideal conditions for very rapid regrowth. We recommend having the pipes inspected and what can be repaired, then fortnightly preventive disinfection. In severe cases, stronger preventive treatment may be needed.

How often should a flat in Al Khansa be disinfected? Weekly or monthly?

The district is very densely built and contaminants return quickly. We recommend monthly disinfection at minimum, and fortnightly if there is persistent smell or young children. A preventive programme works better than waiting for problems to appear.

Does disinfectant kill the fungi growing on damp walls?

The disinfectant kills fungi, but if the underlying moisture is not addressed the fungi grow back quickly. We recommend treating moisture first with ventilation and drying, then applying concentrated disinfectant to affected areas. Ongoing treatment is needed if humidity remains high.

How much does disinfection in Al Khansa 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 Khansa.
