What affects the price

Replacing windows is a custom job, so your final bill depends on a few specific variables. The size and style of the window frames—like double-hung versus large picture windows—play a big role. Choosing energy-efficient glass coatings or adding decorative grids can also shift the total. We also look at the condition of your existing frames and whether the installation requires structural repairs to the surrounding wall. Your exact pricing is confirmed free on the call.

About this service

This covers both fixing minor issues—like broken latches or damaged weatherstripping—and performing full unit replacements. You should look into this when your energy bills rise, your windows become difficult to open, or you notice drafts. Repairs can often extend the life of a unit, but installation is necessary if the frame has rotted or the glass is compromised. A qualified team evaluates whether a simple fix suffices or a complete upgrade is the smarter long-term investment.
