Cutting back Leylandii Cypress
My property has a well established Leylandii Cypress hedge. It stands 10foot high and is approximately 6 - 8 feet wide. The hedge is showing signs of age with an increasing number of brown area's. It is unsightly, but acts as a sound barrier on the local road. My thoughts are to cut back the property side of the hedge back to the trunks, and use them as the supports of a new timber fence, leaving the road side in tact. What effect could this have on the remaining part, as I will be screwing the panel fencing to the bared trucks.

The pruning will not, likely, have much effect, but the type of screw that you use can. Make sure to stay away from copper, aluminum, or anything infused with those metals. They will likely kill the tree. Iron and steel will work just fine, as well as a galvanized zinc material.
Thanks, that is most helpful.
