I’d been thinking about sash windows for my bifold doors now for a decade. I wasn’t sure how much glass we really needed, so I kept putting it off. Then two years ago my partner and I were ready to move into a new home and I finally decided to give Sash Windows London a call. We’re really pleased we did; we had high, ornate sash windows installed in our front bay window and they look awesome. The installation itself was absolutely perfect.
