Fence Company in Gilbert, AZ

Posts and Footings Sized for Ground That Moves

Gilbert's houses are younger than most of the Valley's, and the ground under them is old farm ground that still swells and shrinks, which is why a fence here answers to the soil rather than to the build date.

A Newer House Does Not Mean a Fence That Stays Put

Tempe Fence Company works across Gilbert on both halves of the job: new walls, fences and gates going in for the first time, and the fifteen and twenty year old ones that have started to move. Hiring a fence company in Gilbert, AZ usually starts with a homeowner who is surprised to be making the call at all.

That surprise is fair. Most of Gilbert went up recently enough that nothing on the property feels old. The house is sound, the roof is fine, the paint is holding. Then a gate stops latching, or a post gives when you lean on it, and the assumption that a newer property does not need this kind of work runs out.

What sets the clock on a fence is not the year the house was finished. It is what the ground does, and how deep the original post went to deal with it.

Farm ground behaves like farm ground for a long time

Gilbert was fields before it was subdivisions. Land was leveled for flood irrigation, ditches were cut and later filled, and the soil was worked, watered and amended season after season for decades before a single lot was platted.

That history is still under your yard. Fine soils out here take on water and expand, then give it back and shrink, and disturbed farm ground goes through that cycle enthusiastically. A footing sitting in it rides every swing.

Twenty years of that is enough. It shows up as a post that is no longer plumb, a gate leaf that has rotated out of square with its own post, or a stair-step crack climbing the mortar joints of a block wall that is far too young to be cracking.

Depth and drainage decide the outcome, not the material

Under a lot of this ground sits caliche, a hardened calcium carbonate layer that water does not pass through. Punch a post hole into it and the hole holds water instead of draining. Wood posts rot in a collar right at grade. Steel posts corrode at a waterline down where nobody can see it.

The fix is technique rather than product, and it is three things.

  • Depth. Roughly one third to one half of the height standing above grade.
  • A gravel base, so the hole can drain instead of holding water against the post.
  • Concrete crowned above grade, so water sheds away from the post rather than pooling at it.

Tract fencing gets set to a schedule. That is not a scandal, it is how a subdivision gets built, but it does mean a lot of Gilbert fence lines were set at the shallow end of what works. Year one, nothing shows. Year fifteen, the wind finds those posts, and everybody blames the wind. Wind finds the weak post, not the weak panel.

New Work Here Is a Sizing Question

Plenty of what we do in Gilbert is not a repair at all. Yards get finished later than the house does, side yards get closed in, a pool goes in and needs a barrier, and a bare lot line finally gets a wall. On any of those, the choice that matters is not which catalog page you pick.

It is what goes below grade and how heavy the thing above it is. A six foot vinyl panel catches a great deal of wind for how little it weighs, and every bit of that load ends up in the post. Sizing the footing for the soil and the wind load is the difference between a fence you stop thinking about and one you meet again in a decade.

Sun and heat, not rain, are what age a fence here

Wood does not rot in this climate, it bleaches and checks. The sun opens the grain, boards cup, and the fasteners start to work loose as the wood moves around them. That is a surface and hardware problem before it is a structural one, and it is covered on wood fence.

Vinyl divides sharply by grade. Quality UV stabilized product holds its shape through a full Gilbert summer. Low grade product gets brittle in the sun, then chalky, then it cracks at the rail. On a vinyl quote the product grade is effectively the whole quote, which is the point of vinyl fence.

Young block walls crack too

A block wall built in the last twenty years is not exempt from any of this. It is heavier than a fence, so it telegraphs footing movement more clearly, and a wall that is out of plumb has a footing problem rather than a block problem. Restacking the block over a footing that already moved buys the same lean back.

The advantage of catching a young wall is that the damage is usually still local. One section, sound block on both sides, and a repair that stays inside a few feet of it. Which call your wall gets is on block wall repair. Where a run is genuinely past saving, or where there was never a wall to begin with, that is block wall construction.

Where We Work in Gilbert

Gilbert's oldest neighborhoods sit at the north and west end, closest to the Mesa and Chandler lines, and those are the fences arriving at a first real repair now. Posts, gates and side yard runs mostly, with block walls that are old enough to have opinions about the ground under them.

Head south and east and the subdivisions get newer as you go. Out there the calls are still mostly new work: finishing a yard, closing a side gate, enclosing a pool, putting a wall where the builder left an open line. Same soil, earlier in its argument with the fence.

Everywhere in between, the lots that back onto or sit near old irrigation runs and open ground are the ones where the soil moves most, and they are worth a closer look at the base of the fence line. We reach all of it from Tempe on the 202 and the 60, and there is no long-distance markup for crossing the town line.

What a first visit looks like

Someone comes out and pushes on things. Posts get tested for movement at the base, gates get checked square against their own posts rather than against the latch, and the ground at the fence line gets looked at for what the irrigation and drainage are doing to it.

Then you get a price in writing covering exactly what the work includes. The visit is free, there is no obligation at the end of it, and if the honest answer is that your fence has years left in it, that is the answer you get.
