March to May: the pre-summer sprint and heat-reflective coatings
Spring is when smart villa owners do the work that pays off in their DEWA or ADDC bill. Heat-reflective exterior paints — sold in the UAE under names like Jotun Jotashield Extreme and equivalent National Paints and Caparol lines — use infrared-reflective pigments to bounce a meaningful share of solar heat off the wall before it soaks into the block. Applied to a west- or south-facing villa elevation before June, they measurably lower the heat load the AC has to fight all summer. Applied in September, you have paid for the benefit and missed the season it matters most.
Expect the pre-summer sprint to be a seller's market for exterior work by late April. Interior work, by contrast, is easy to book in spring — which makes March to May a good moment to compare several painting vendors side by side in the tamam app, where quotes come as transparent AED ranges rather than a single take-it-or-leave-it figure, and pick a slot before the summer interior rush begins.
