Why they keep coming back in Harat Al Sarahin

Mud walls absorb salt and sea humidity very quickly. The shared courtyard between houses is an entry point for pollutants from both the sea and the street at once. The method is set out in full on our Disinfection service.

The first reason

Old mud walls absorb sea humidity and salt very quickly

Clay is highly porous and salt and moisture seep through it rapidly. Disinfectant does not grip damp surfaces well. We choose products safe for mud and suited to damp surfaces, and leave the product longer to work.

The second reason

Clustered houses share the courtyard, passages and air

Close families live in adjoining houses and a shared courtyard between them. Pollutants travel from house to house through the yard and air. We treat the yard and shared passages as a single system.

The third reason

Sea salt remains in the air and walls throughout the year

Sea wind carries salt and humidity year round. Disinfectant weakens under this constant pressure. Daily or weekly disinfection is not enough. Repeated reapplication is necessary.

Before treatment

What we look at before the product is chosen

A very old quarter in the coastal town of Thuwal where unfit homes are gradually being replaced. The mud houses are aged and walls are continuously damp from salt and the unending sea air.

The touch points

Old mud walls are highly porous. Every surface is a touch point. Salt and moisture seep through any small gap. We focus on deep treatment.

Porous surfaces

Surfaces are mud, old concrete and rammed earth. Each material is different and needs matched treatment. Disinfectant reaches mud but slowly.

The finish itself

The natural clay finish has no paint. Disinfectant reaches the surface directly but humidity weakens it. We choose products that withstand constant damp.

The air conditioning unit

Air conditioning is old or absent. Windows and basic air holes let salt and humidity enter. We disinfect openings and windows heavily.

Floor traps

Floor traps are basic or may be a hole in the ground. Water collects and humidity is constant. We treat very deeply and wait.

Shared entrances and stairs

The shared yard and tight passages between houses are high-traffic contamination points. Visitors and animals pass through them. We focus on deep treatment.

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 Sarahin

Mixed district: shops at street level with homes above them

A mixed district means old popular houses and some have small shops on the ground floor. Families cluster together and share the courtyard and passages. Pollutants from the shop, street and sea all enter the homes together.

Questions about this district

The mud house walls stay wet all the time; does disinfectant work on damp mud?

Yes, but we must choose products safe for mud and suited to humidity. Disinfectant needs longer to dry and moisture returns quickly from the sea.

The shared yard between houses; do we clean it first or disinfect it directly?

We clean the yard first to remove dust and dirt, then disinfect with products safe for soil and mud. The shared yard needs deep treatment.

Should we disinfect before walls dry or after we dry the salt away?

We disinfect after cleaning and drying as far as possible. But mud walls are naturally damp. We choose products that work on moisture, not waiting for full drying.

Sea salt returns after disinfection; how often should we treat?

Salt returns quickly. Weekly disinfection works better than monthly. But sealing windows and gaps matters more than repeated treatment.

The houses are very old; are they clean inside or is there constant moisture?

Mud houses have continuous moisture from foundation and walls. We disinfect but do not expect long protection. Moisture is permanent.

Is there special treatment for the mud house or ordinary disinfection?

Yes. Mud is sensitive. Strong products may damage old mud. We choose products safe for mud and let the disinfectant soak into surfaces.
