Caulk is relatively inexpensive and easy to apply. Caulk serves several purposes:
- It seals cracks which rob your home of conditioned air, making it more energy efficient.
- Different materials expand and contract at different rates and at different temperatures. Flexible caulk can seal the cracks that result from this movement.
- It provides a moisture barrier and seals water away from areas which could be damaged by rot or by the expansion of water as it freezes.
- It prevents insects from crawling through cracks into your home.
- It provides an attractive finish in corners and at the joints of unlike materials.
