Englewood Stem Wall Contractors

You can learn a surprising amount about a house without leaving the sidewalk, and most of it is written on the band of concrete between the siding and the dirt. That strip is the only part of the foundation anybody ever sees, which means it's also the only part anybody ever tries to fix cosmetically. Paint, parge, veneer, a smear of something black. Each of those was somebody's answer to a problem, and the answer usually tells us more than the problem would have.

We repair and replace stem walls throughout Englewood, and on older streets the first thing we do is read the face. Not to judge whoever painted it. To work out what they were looking at when they decided painting was the move, because that condition is still down there under the coating, and it has had years to get worse in private.

What that exposed strip is actually for

People treat the visible part of a foundation as trim. It isn't. It's a wear surface doing three jobs at once, and none of them are decorative.

First, it takes the splash. Every rain that hits the ground next to your house comes back up onto that concrete carrying grit, and every winter it gets hit with whatever melts off the walk. Second, it's the last few inches of a moisture path. Water that gets into a wall from the buried side travels up and leaves through the only face that's open to air, which is exactly the face you're looking at. Third, it holds a gap between wet ground and wood.

So when that band starts breaking down, the concrete is rarely the villain. It's the messenger. Something is either delivering more water to the wall than the wall was built for, or preventing water already in the wall from getting out. Coat over it and you've picked the second option on purpose.

Reading a painted foundation from the sidewalk

Paint fails in patterns, and the pattern is the message. A blistered band that runs level along the whole front, a few inches above the dirt, means moisture is coming through the wall and pushing the coating off from behind. That's a drainage story, not a paint story, and no primer solves it.

Peeling concentrated at one corner is a downspout. Nine times out of ten you'll find the elbow right above it, dumping into the same square foot of dirt it has been dumping into for years. A patch of newer paint in an odd shape means somebody repaired something and matched the color, and we'd like to know what was under there.

Then there's the wall where paint is holding beautifully everywhere except right where a walk or patio meets the house. That joint is where water gets trapped, and it's the spot we open first. Around Northwest Englewood we see it constantly, because the walks are old, they've settled toward the house, and the concrete has been quietly drinking for a long time.

What's on the face, and what it's really doing

Walk a lap of your house and look for these

• A level band of blistering or breakdown that runs regardless of where the downspouts are
• Breakdown that stops and starts, which points at one specific water source
• Anywhere a walk, patio, or driveway meets the wall, and which way that concrete slopes
• Coatings or veneer that continue below the dirt instead of stopping short of it
• Rust staining running down the face, and whether it comes from a bolt or from inside
• The line where siding stops, and whether it's the same distance off the ground all the way around
• Any spot where you can push a screwdriver into the surface without much effort

When the wall looks worst, and when we'd rather work on it

March is the cruelest month for a stem wall face and the most useful one for looking at it. Snow has been sitting against the concrete for weeks, the wall is saturated, and warm afternoons followed by hard nights work on that moisture over and over. Whatever is failing shows its full extent right then. A wall that reads fine in August can look genuinely alarming in early spring, and the March version is the honest one.

Repair work runs the other way around. We'd rather have late summer through fall for anything that opens a trench against the house, because the excavation stays stable and there's time to correct the drainage, treat the buried face, and put the grade back before the ground locks up.

Pours happen in cold months too, with heated mix water, non-chloride accelerator, and blankets, and never on frozen bearing. It's the backfill we hold the line on. Frozen material doesn't compact, it bridges, and it comes back in spring as a settled walk pointing right at the wall you just paid to fix.

You can nearly always find the downspout without looking up. Stand back on the sidewalk, find the worst three feet of the foundation, then raise your eyes. It's right there, above the bad spot, every time. Same house, same corner, twenty years running.The crew lead's read on it
