The Window Doctor repairs existing windows as well as replacing them.

A 2026 customer said the company quickly diagnosed and repaired a window, avoiding the cost of replacing the whole window. A 2026 customer said The Window Doctor replaced fogged glass instead of entire windows, inspected all the windows and made inexpensive repairs that saved thousands of dollars.

That 2024 customer said the bill came in below the quoted budget.
