Replacement vs. New Sliding Window Installation

A replacement sliding window is usually much less expensive than a brand-new installation. When you replace an existing window in the same opening, labor is more predictable and generally less involved.

A brand-new installation costs more because contractors may need to cut into the wall, reframe the opening, install new headers or trim, and repair interior and exterior finishes. Labor for this type of work can make up the largest share of the project budget.
