Degraded sealant and what it lets in
A joint that has stopped sealing is a path for water and pests.
In short: Sealant is consumable. Once it fails, the joint behind it is open.
What sealant does
Closes a joint that has to move, keeping water and pests out of it.
How it fails
It hardens, shrinks and cracks with age and UV, then sections go missing.
What we recorded
Sealant old, with sections missing or degraded, on an established property nearby.
Why pests care
An open joint is both a moisture path and an access route.
What to do
It is maintenance, and cheap. Reseal before it becomes a water problem.
