This page lists it as one of the requirements the job had to meet, along with local fencing rules and electrical safety. The metal fabrication also had to be cut to match the property layout rather than built to a standard run.
Before anyone sets a post, agree in writing where the line is and what you are relying on to prove it. That conversation is much cheaper than moving a finished fence.
That is exactly what this job had to fix first. The page records uneven ground and drainage problems that needed grading correction before any turf went down, then a base prep and a drainage layer under it.
The turf is the last part. If someone quotes you turf without talking about what is going underneath it, that is the thing to press on.
Not on this build. It is a Trex composite deck with a hidden-fastener system and matching fascia, and the page records it as needing no annual maintenance.
Composite costs more up front than wood and that is the trade you are making. Ask what the board carries in its own manufacturer warranty, and get the product line written into the quote rather than just the word composite.
