External Window Sealing and Caulking


Well-sealed windows prevent a variety of problems.

Poorly sealed windows leave gaps for water to infiltrate between the window and siding, causing the siding to deteriorate more quickly.


These gaps also allow air flow into and out of the building, resulting in higher heating and air conditioning costs.

The condensation generated by this air flow can also cause the building structure and windows to deteriorate prematurely.


Procedures:


  • Choose the right sealant
  • Remove old sealant
  • Clean the surface before sealing it
  • Apply sealant primer
  • Place backer rods if necessary
  • Apply the sealant
  • Shape the joints
