Al Swydy sits at 24.5912, 46.6730, about 13.6 km from the centre of Riyadh, with an approximate radius of 3.2 km, and it has both villas and apartment buildings. Before any spray foam work is quoted for an apartment here, the first check is the building's location and its exposure. The centre of Al Swydy sits about 619 m above sea level, and the nearest wadi channel is about 0.2 km from the centre. Because the neighbourhood is close to a wadi, we look at how water moves across the site after rain, not only at the walls themselves. Our technician notes whether the apartment is on a lower floor, whether it shares a wall with a ground-level area, and whether any part of the building could be affected by runoff from the channel.

Several things can only be judged on the day of the site visit. The technician checks the condition of the existing walls, roof slab and any visible cracks, and decides whether crack injection is needed before foam is applied. Spray foam for apartments is typically priced in the range SAR 20–45 per m², while crack injection is priced separately at SAR 40–125 per metre, so the measured length of any cracks changes the final figure. The technician also confirms the surface area that will be treated, checks moisture levels, and decides whether a different system, such as liquid roof waterproofing at SAR 10–25 per m² or XPS boards at SAR 15–30 per m², suits a particular part of the property better. None of these decisions should be made from a distance.

To help the technician prepare, it is useful to have the apartment's floor plan or rough measurements ready, along with the floor level and the building's age. Please note any past leaks, damp patches or areas where paint has bubbled, and say which rooms are used most. Clear access to the roof, balcony or ground-floor wall is also helpful. If the apartment has a bathroom, mention it, because bathroom waterproofing is priced separately at SAR 15–40 per m². Providing these details lets the visit focus on the real problem areas and gives you a clearer picture of what the work will involve.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
