Patio doors

Can you replace a patio door with a window?

Yes. We reduce the opening, rebuild part of the wall (structure, insulation, air barrier), then install the window(s). Interior finishes and exterior cladding follow.

Why people do it

Less heat loss, more furniture against the wall, or a rarely used patio. We price the full job to avoid surprises.
