Couldn’t be more pleased!
Had some exterior wall cracks from the extreme drought, which we didn’t want to grow. Bruno inspected & recommended HelicalBar’s which would rectify the problem. Ryan performed the work, a brilliant job. We couldn’t be more pleased with the results!

Wall Cracks For a Double Brick House
After installing the HelicalBar, they properly patched the wall with cement. The bars in the external wall were installed well and are invisible (very straight now). They are also sealed very well. We are very happy with the process and results.

Geopoly & HelicalBar Install
I’m very happy with the outcome of the GeoPoly and Helical Bar installation. The garage and adjoining walls look 100% better and I’m no longer concerned about falling bricks and sinking foundations. I would not hesitate to have BuildFix back again.
