Should I reseal my villa windows before winter rain and dust in Sharjah?

Yes — October and November are the best months to reseal villa windows in Sharjah, at roughly AED 50–120 per window (indicative only — actual costs vary)

Sharjah's winter rain usually arrives between December and March, and it often comes in short, heavy bursts driven by wind, which is exactly when cracked sealant around window frames lets water in. Autumn is ideal because surfaces are cooler, so new silicone cures properly, and you catch problems before the first storm. Resealing typically costs AED 50-120 per standard window, and a whole villa commonly comes to AED 800-2,500 depending on the number and size of windows and whether sliding door tracks are included. Replacing worn rubber gaskets and brush strips on sliding units adds a little more but makes a big difference to dust.

Why seals fail in Sharjah's climate

A summer of surface temperatures well above 60°C on sun-facing frames makes silicone harden, shrink, and pull away from the wall or frame. Aluminium frames also expand and contract daily, which gradually opens hairline gaps at the joints. Once gaps form, fine dust blows in during shamal winds and rainwater can track behind the frame into the wall, sometimes showing up later as stained paint or damp patches below the window. Checking the outside face of each frame for cracked or missing sealant is the quickest way to judge how urgent the job is. Door thresholds and the joints where window sills meet the wall are other common weak points worth including in the same visit.

What to watch out for

Ask the contractor to fully remove old sealant rather than running new silicone over it, since sealing over failed material rarely lasts more than a season. A UV-resistant, exterior-grade neutral-cure silicone is the right product for Sharjah's sun, and drainage holes at the bottom of sliding window tracks must be left clear, or rainwater will pool and overflow indoors. For high windows, confirm how access will be managed and whether a ladder or small scaffold is included in the price. If a window leaked last winter, have the contractor check whether the problem is the frame seal or a crack in the wall around it. It is also sensible to combine the work with a check of roof drains and balcony outlets, since blocked outlets are another frequent source of winter leaks in Sharjah villas.
