How do I know if my window needs to be repaired or replaced?
Windows often need repair when minor damage occurs, but frequently replacing them is necessary if the frame or glass is beyond repair. Replacement can enhance energy efficiency and save money on bills.
Foggy windows often result from seal failure. Replacing the glass unit restores insulation, improving energy efficiency.
The process frequently takes a few hours per window, depending on the complexity.
Costs vary depending on size, type of window, type of glass. But replacing window glass units always pays off by enhancing energy efficiency and reducing heating/cooling expenses.
We frequently offer energy-efficient options like double-pane, single pane, anneal, Low-E or tempered glass, designed to enhance insulation and save money.
Proper maintenance, such as cleaning and inspecting seals, often helps windows maintain their energy efficiency and long-term performance.
