Signs of Exterior Wall
Deterioration
-
Cracks
Most leaks stem from cracks in the exterior wall. We repair them with plasticizer-free elastic material to prevent recurrence.
-
Chalking on the Paint Surface
This is when UV rays break down the paint film into a chalky powder — a sign the coating is nearing the end of its life.
-
Around Windows
Sealant hardens and peels away over time, causing leaks. We always replace the existing sealant before applying new work.
-
Concrete Spalling
Water enters through cracks, causing the rebar inside to rust and expand, which breaks apart the concrete. This needs urgent repair.
