Fencing
Fencing that's still standing straight after the first winter storm.
Slatted or panel fencing, set on posts that are actually concreted in, not knocked into loose ground.
Posts set below frost depth and concreted, so the fence doesn't move with the ground.
Slatted, panel or closeboard styles, built to the height and privacy you need.
Gates hung properly, not an afterthought bolted onto the end run.
Existing boundaries checked before work starts, so there's no dispute later.
