Spray foam insulation for apartments in Jeddah
In short: In Jeddah (Jeddah), spray foam insulation for apartments begins with the roof, falls and drains survey and the thickness measurement at spread-out points; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Published price: Spray foam (per m²), SAR 20–45 per m²; anything else is quoted after the inspection.
Before we start: what we know about Jeddah
Team note on Jeddah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
Jeddah is about 2 km from the sea coast (OpenStreetMap).
Jeddah's coastal climate brings high humidity and strong afternoon heat, and apartment owners there often ask whether spray foam can be applied to an existing building without tearing out finishes. Most of the questions we see concern retrofitting, since a building that is already occupied and finished presents different constraints than new construction. For this service, the first thing checked in an apartment is the wall and ceiling condition behind the finishes, especially around window frames, balconies and the roof slab. Moisture from humidity can be trapped by foam if the substrate is not dry, so the team looks for signs of past leaks and damp patches before any product is chosen. Where the apartment sits on a lower floor or includes a basement wall, the basement wall rate of 55 to 160 riyals per square metre is a useful reference for budgeting that part of the job, while a bathroom or balcony floor treatment falls between 15 and 40 riyals per square metre. Before the visit, it helps to note which rooms feel hottest, any existing cracks or stains, and which areas you want treated first. Ask the team whether a protective or reflective coating at 10 to 30 riyals per square metre would suit the exposed surfaces, and how foam compares with other insulation types for your specific walls.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
Signs that call for spray foam insulation
The following signs are worth checking before they grow:
- Thermal and water insulation needed together
- A hot metal-sheet roof or hangar
- Leaks from the panel joints
Where the problem usually comes from
- A common cause: no UV protection on the surface.
- Joints in metal sheets and sandwich panels — we check this before anything else.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Jeddah |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
How the work is done, step by step
- Survey: Joints, fixings and gutters are checked.
- Preparation: The surface is cleaned and dried.
- Spraying in layers: Foam is applied in passes to the agreed thickness.
- Protection: A UV-resistant top coat protects the foam.

Short answers for Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
What is the first step of spray foam insulation for apartments?
We start with survey (joints, fixings and gutters are checked), then preparation (the surface is cleaned and dried).
