How Much Does It Cost To Seal Windows?

How to Seal

Each window pane is mounted in a framework called a sash. The pieces of the sash that surround the panes are specially designed to hold the glass. Some use a seal of pre-shaped material, while others use a compound called glazing putty to seal the gap. Each sash is mounted in a jamb. For windows that open, the sash slides or turns inside the jamb. All movable junctions require special care to remain sealed and continue to function properly. The entire window, the jamb mount inside the window frame and every junction between them must be sealed.

Cost Variances

While sealing the window, the contractor examines all the seams of the jamb and frame for signs of decay, moisture damage or cracks. Any repairs or upgrades needed can add to the cost. The amount of sealant required may vary according to the size and condition of the window. Any mechanical problems or movements that are binding should also be replaced prior to sealing, and installing those materials adds to the overall cost.

Opt for a Professional

The window consists of several layers, and sealing them can be an involved process. It's recommended that each one is inspected by an experienced contractor for signs of damage or worn out movements. Their knowledge and expertise helps to identify deep-rooted problems and ensures the seal is thorough and long lasting.
