Water Inside a Window After Rain
Likely cause: Gap between frame and wall.

Resealing from AED 150*
Exterior Caulking and Window and Door Resealing in Dubai
Water that runs down a wall during rain finds its way in around window frames, door frames and movement joints wherever the sealant has cracked. Sun-baked silicone shrinks and peels. We cut out old sealant and reseal frames and joints with UV-resistant sealants.

Process
How We Reseal Windows and Doors
- 01
Cut Out Old Sealant
Cracked, peeling sealant is cut out completely, not covered over.
- 02
Clean and Dry
Joints are cleaned of dust and old residue and left dry.
- 03
Backer and Prime
Backer rod is fitted in deep joints and primer applied where needed.
- 04
Seal and Tool
New UV-resistant sealant is applied and tooled to a neat bead.
Sealant Is a Maintenance Item
Exterior sealant does not last forever in Dubai sun. Most need renewing every five to eight years. Sealing over old, cracked sealant just traps dirt and fails again quickly, so we always cut it out first.
Different joints need different sealants. Window perimeters, movement joints and roof penetrations each have suitable products rated for UV and movement.
For windows, see window seal replacement. For walls, see waterproof coatings, and for roofs, roof maintenance.
Before Winter
Check exterior sealant every autumn before rain arrives.
Inside Too
Brush seals inside sliding windows are a separate repair.
Sealed Tight
Windows, Doors and Joints Resealed

Exterior Caulking and Resealing: FAQs
How Much Does Window Resealing Cost in Dubai?
Exterior window and door resealing starts from AED 150 per opening. Movement joints are priced per metre. Prices vary and can change depending on your exact requirements, the materials and access to the property, so the final price is confirmed after we see photos or visit.
What Should I Do the Moment I Notice a Ceiling Leak?
Move furniture and electronics away, put a bucket under the drip, and switch off lights or sockets near the water. If the ceiling is bulging, keep people out from underneath, then call us or your building management.
Which Waterproofing System Is Best for Flat Roofs?
For most Dubai villa roofs, a liquid polyurethane membrane works well because it is seamless, UV resistant and flexes with heat. Bitumen membranes suit full re-roofing, and cementitious coatings suit wet areas under tiles.
Do You Offer Emergency Roof Leak Repair?
Yes. During and after heavy rain we prioritise active leaks, aiming for same-day visits where possible to make the roof safe with temporary sealing, then return for the permanent repair once the roof is dry.
