Picture a family that has just agreed to buy a villa in Khamis Mushait. The house is solid and well kept, but the roof slab is warm to the touch in the afternoon, the walls of the upper floor feel cold in winter, and the new owners want to add insulation before they move in. They are weighing spray foam against the cheaper options they have heard about from neighbours, and they want to know what the work will realistically cost before they commit.
The local setting matters. The centre of Khamis Mushait sits about 1998 m above sea level, so the town is high, and the nights in the cooler months can be noticeably colder than the coastal cities. That makes a warm, draught-free envelope more useful than many buyers expect. Spray foam insulation is typically priced in the range of SAR 20–45 per m², while XPS boards fall in the range of SAR 10–30 per m². Where a roof leaks or a basement is damp, waterproofing comes first: liquid roof waterproofing is SAR 10–25 per m², bitumen membrane SAR 15–35 per m², and basement waterproofing SAR 50–145 per m². Insulation laid over a wet surface only traps moisture, so the order of work is important.
Before buying or taking handover, walk the property with the seller or agent and check the roof, the basement walls and any cracks. Note every crack and ask for a quote per metre for crack injection, which is SAR 40–115 per metre. Ask the contractor to state the area being covered and the rate used, then multiply it out so the figure can be checked. Request the scope in writing, confirm whether the price includes surface preparation, and agree a payment schedule tied to completed stages. Finally, confirm that any waterproofing is finished and dry before spray foam or boards are applied, and keep copies of every invoice and product specification for future maintenance.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
