“What’s the standard size for my windows?”

It’s a question we hear time and again, and the truth is, there isn’t one!

As homes age, the framing shifts. And the window opening that was built decades ago may not be exactly the same size today.

That’s why every project starts with an in-home consultation and precise custom measurements.

These measurements are an essential part of the WoW process and ensure:

🪟 That even windows that might look the same are custom manufactured and guaranteed to be a perfect fit.

🪟 Increased energy efficiency and a lower probability of drafts.

🪟 A better, more aesthetic appearance. (Fun fact: many manufacturers measure small. It guarantees the windows will fit on install day, but the contractor has to use larger capping details on the exterior to cover the gap - making the window frames look bigger and boxier than they are.)

When it comes to replacement windows, the best results start with accurate measurements, not assumptions.
