Phoenix Block Wall Repair That Fixes the Cause

Desert Block Wall Phoenix has masons who repair cracked, leaning and fallen block walls across Phoenix. Block wall repair in Phoenix is mostly detective work, because the crack you see is a symptom of something under the wall.

The usual causes are a shallow footing, tree roots lifting one side, sprinkler water soaking the soil, or a car or monsoon gust hitting a wall with no steel in it. If we patch the crack and leave the cause, it comes back.

We cut out the damaged section, fix the base, and rebuild with new block tied into the sound wall on each side.

How a Repair Visit Works

  1. Inspect. We check the crack pattern, plumb, footing and anything nearby: trees, sprinklers, slopes.
  2. Explain. You get the cause and the fix in writing before any work starts.
  3. Rebuild. Damaged block comes out, the base gets fixed, new block goes in tied to the old.
  4. Finish. Cap, stucco and paint matched so the repair doesn't stand out.

Block Wall Repair Questions

Is a cracked block wall dangerous?

A hairline crack usually isn't. A wall that's leaning, has a widening crack or moves when pushed can fall, especially in monsoon wind. Keep people away from it and have it inspected.

Can you match my existing block?

We get close, but old block fades. For a clean match we often refinish the repaired section and the wall next to it with stucco or paint.

Who fixes a shared wall?

That's up to you and your neighbor. We can meet with both of you and write one scope.

Will homeowners insurance cover a fallen wall?

Sometimes, after a storm or a vehicle impact. We'll give you photos and a written scope to send to your insurer.
