Keeping Your Car Watertight in UAE: A Guide to Seals and Weatherstripping
The UAE is one of the driest countries in the world, but when it rains here it tends to rain hard and quickly. Brief but intense rain events, particularly during the November to March season, can flood streets and expose weaknesses in a vehicle that have built up over years of dry conditions. A car that has not been driven in rain for months may turn out to have multiple failed seals that have never been tested. This guide explains which seals keep your car watertight and how to check if they are still working.
Door Weatherstrip Seals
The most important seals for keeping water out of your car cabin are the door weatherstrips, also called door seals or door rubbers. These are the continuous rubber profiles that run around the perimeter of each door opening. When you close a car door, the weatherstrip compresses and forms a seal between the door and the body of the vehicle. In UAE conditions, these seals degrade from UV exposure and heat cycling and lose their compression and sealing ability. Test your door seals by closing each door on a piece of paper. If the paper can be pulled out without significant resistance, the seal at that point is no longer providing an adequate compression seal.
Windscreen and Rear Screen Seals
The rubber seal or adhesive bonding around the windscreen and rear screen prevents water entry at the glass-to-body joint. A cracked or failed windscreen seal allows water to enter the A-pillar channel and drip onto the dashboard or footwells. In the UAE, windscreen seal failure is often first noticed during car washing. If water drips from the A-pillar trim after washing, the windscreen seal requires attention. Windscreen resealing at a UAE garage costs AED 100 to AED 300 depending on the extent of the seal failure.
Sunroof Seals and Drains
Vehicles with sunroofs have both a seal around the glass panel and a system of drain channels that carry water that gets past the seal away from the headliner. In UAE vehicles that rarely use the sunroof, the drain channels can become blocked with fine desert dust, causing water to back up through the sunroof into the headliner and ceiling when rain eventually comes. If you have a sunroof, run the drain channels clear with a length of flexible wire or compressed air at least once a year before the UAE rainy season. Also check the sunroof seal for hardening and cracking.
Boot and Tailgate Seals
The seal around the boot lid or tailgate is exposed to less UV radiation than door seals but still degrades over time. A failed boot seal allows water entry into the luggage compartment, where it can damage electronics in the spare wheel well, soak carpets, and create mould in a sealed environment. UAE SUV owners should check the tailgate seal annually and look for any gaps visible when the gate is closed by running a torch around the perimeter in a dark garage.
How to Maintain Car Seals in UAE
Apply a silicone-based rubber conditioner to all door and boot seals every 6 months. This keeps the rubber flexible and prevents the hardening and cracking that leads to seal failure in UAE heat. Avoid using petroleum-based products or WD-40 on seals as these degrade rubber compounds. Silicone spray or a dedicated rubber treatment product available at UAE car accessories outlets is the correct choice. Conditioned seals last significantly longer in UAE conditions than untreated ones.
