lacecap hydrangeas and pruning

[amverytired]

I have several of these in the garden of our new house. One is by the front door. It's still flowering, but it's getting too big for where it is - as in, it's hanging over the path and the top of it is getting too high (relative to the window).
I want to just chop off the bits that are in the way, but will I ruin the flowers for next year if I go at it with the secateurs?
any tips appreciated!

You probably will lose next years flowers if you chop it all back at once. Why not cut some of the branches back now & then next year cut back the other ones after they've flowered? That way you will still get some flowers & will have it pruned to size in a couple of years.
