Sanctus Builders builds fencing, gates and retaining walls across Christchurch, built to survive a Canterbury winter and hold their line for years, not just look good on installation day. Felipe scopes the section, checks what's actually holding the ground or the boundary in place, and gives a straight price before any post goes in.

"Fencing & Retaining Walls" covers three kinds of work, each with its own structural considerations.
Boundary and privacy fencing built with posts set deep enough to hold against Canterbury's clay and wind exposure, not just deep enough to pass a quick look.
Pedestrian and driveway gates built to match the fence line, hung so they still swing true after the ground shifts a little over a Christchurch winter.
Timber or block retaining walls that hold back a slope or level change, built with the drainage behind them sorted properly, not just the wall itself.
Fencing and retaining walls both look like a straightforward build from the outside, but what happens below ground is what decides whether the job holds up. Here's how Sanctus Builders approaches it.
Felipe checks the boundary line, the ground condition, and what's causing any slope or level change.
Timber, block or a mix, chosen for what the section and the job actually need.
Posts get set to depth, and retaining walls get proper drainage behind them, not just backfill.
Rails, palings, gates and capping finished so the job looks as solid as it actually is.
No drainage behind the wall, so water pressure builds up and pushes it out over time.
Footings that aren't deep enough for the height and load of the wall.
Timber in ground contact that isn't treated for the job it's doing.
A wall built to hold back more ground than it was actually designed for.
Sanctus Builders treats drainage and footing depth as part of the wall itself, not an optional extra. A retaining wall that's built properly the first time doesn't need rebuilding in five years.
Sanctus Builders holds a five out of five rating across Google and Builders Crack. Here is what some of those customers had to say.

It depends on the height and length of the wall, the ground condition, and whether it's timber or block. Sanctus Builders quotes after seeing the section, since drainage and footing needs vary a lot from site to site.
It depends on the fence height and the ground condition, but posts always get set deep enough to hold against wind and ground movement, not just deep enough to stand up on the day it's built.
