Eighty-year-old brick, mid-test
Affton's blocks of 1940s-50s brick bungalows and story-and-a-halfs are the metro's workhorse housing: solid, unpretentious, and now deep into the decades where clay cycling shows. Full-brick construction is heavy and stiff: it telegraphs settlement early as stair-step cracks over windows and at porch returns, and it rewards early underpinning because the structure lifts clean. Basement walls are early block, bowing politely at mid-height where Gravois Creek-bound drainage kept the clay wet on one side of the street.
Sensible fixes at Affton prices
These are compact foundations: short pier runs, one or two walls needing restraint, scopes that land low in the metro range far more often than not. The pattern to push against: decades of quick tuckpointing over moving cracks. Re-mortar hides the testimony but not the movement; a measured evaluation, a modest structural fix, and then the repoint, in that order, is how an Affton bungalow gets another eighty years.
Asked in Affton
Is repair cheaper on a small Affton bungalow?
Generally, yes: smaller footprint means shorter pier runs and fewer straps, and Affton scopes land at the low end of the metro band more often than not. Brick-on-block construction is also honest: it shows movement early, while the fix is still small.
Decades of tuckpointing keep cracking. What now?
The wall is moving and the mortar keeps confessing. Measure first: floor levels and crack mapping tell whether it's active settlement or old movement plus thermal cycling. If it's active, a short pier run ends it; then the final repoint actually holds.
