Nearly every article about tuckpointing tells you to look at the weather elevation — the west or northwest wall that takes the wind-driven rain. That is good advice in most of Chicagoland.

In Worth, start at the bottom instead.

The village sits low, in the Cal-Sag corridor, on flat ground with heavy clay soils that hold water rather than shed it. Much of the housing stock went up through the 1950s and 1960s on lots with very little fall away from the house. The result is a local pattern we see over and over: a wall that is perfectly sound at eye level and genuinely finished in the three courses closest to the ground.

Why the base courses fail first here

Four things converge on the bottom of a wall in Worth, and they compound.

Splash. Rain hitting flat ground next to the foundation bounces back into the lowest courses — thousands of impacts a season, delivering far more water to that band than any other part of the wall receives.

Grade that has crept up. Decades of mulch, regrading and landscaping raise the soil line. Brick that was built to sit above grade ends up in direct contact with wet clay.

Snow. Shoveled off the walk and piled against the wall, where it sits for weeks and melts slowly into the same courses.

Salt. De-icing salt from walks and driveways arrives in solution, moves into the masonry, and crystallizes inside the pore structure. Salt crystallization is a mechanical process — it breaks the material apart from within.

Then the freeze-thaw cycle does the rest. Chicagoland runs through dozens of crossings of 32°F in a typical winter, and each one catches that saturated band wet. Wet masonry plus repeated freezing is the entire mechanism of mortar failure, and no part of your wall is wetter for longer than the bottom of it.

So a Worth assessment starts with a hand on the base course, not a look at the gable.

The rest of the house, in order

Once the base courses are accounted for, the honest priority order on most Worth properties looks like this:

1. The chimney. Exposed on four sides and the top with nothing sheltering it. Chimneys weather on a much faster clock than walls, and it is entirely normal for a chimney to need full repointing while the house needs very little.
2. The base courses and splash line. For the reasons above.
3. Anywhere water is being delivered by something broken — an overflowing gutter, a downspout discharging at the foundation, a sill that has lost its pitch, a rusting lintel over a window.
4. The weather elevation. West and northwest facing, where joints recede behind the brick face.
5. The shaded elevation. North walls and gangway walls that get almost no solar drying and stay damp days longer after rain.
6. Everything else, which on a lot of houses genuinely does not need doing yet.

Check your own mortar in ten minutes

You do not need a contractor to tell you whether a joint is finished.

The key test. Push a house key or flat screwdriver tip firmly into a joint and drag it. Sound mortar resists — it scratches but does not give. Failed mortar crumbles, or lets you rake out a channel of sand.

The recession test. Sight along the wall at a low angle. Mortar should sit at or just behind the face of the brick. Joints receded a quarter inch or more, so the units read as individually raised, have lost real section.

The floor test. In the basement, look along the base of the foundation wall. Sand and grit accumulating there is mortar leaving the wall.

Do that at a dozen points — a few per elevation, high and low, plus the chimney and the bottom courses — and you have your own scope to hold any proposal against.

How the work is actually done

Tuckpointing that lasts thirty years and tuckpointing that falls out in three look identical the week it is finished. The difference is in the execution.

1. Cut out to depth — roughly two and a half times the joint width. For a standard three-eighths inch joint, close to an inch. Grinders on bed joints where appropriate, hand tools at head joints and anywhere the brick is soft.
2. Never skim. Troweling fresh mortar over failed material is the defining shortcut in this trade. It has nothing to bond to.
3. Clean the joint. Dust and loose material brushed and blown out — a dusty joint prevents bond.
4. Match the mortar. Type N for most residential and light commercial work of this era; Type S only where exposure or structure genuinely calls for it. Mortar always stays softer than the unit it holds, so it remains the sacrificial element.
5. Match color and texture against a cured sample. Wet mortar reads a different color than set mortar, and matching wet is how walls end up two-tone.
6. Pack in lifts on deep joints, compacting each pass.
7. Tool to the original profile — concave, weathered, struck. The profile is part of how the wall reads and part of how it sheds water.
8. Cure and protect. Kept damp and shaded in summer heat so it does not flash-dry; heated and covered in cold, or scheduled for a workable window.

Fix the water, or do it again

On a Worth property this is not optional advice. Repointing the base courses while a downspout still discharges at the foundation is scheduling the same job for a second time.

Before or alongside the masonry, we look at:

• Downspout discharge — extended well away from the house, onto ground that falls away
• Gutters — overflow sheets water down a wall all season
• Grade — the ground should fall away for the first several feet
• Soil height against the base course
• Sump discharge, which we regularly find running back toward the foundation
• Sprinkler heads aimed at the house

That work is usually the cheapest line in any masonry scope and the one that protects everything else in it.

What drives the cost

The wall area actually failing, not the size of the house. How many elevations are involved. Height and access — a two-story rear elevation over a deck is not a front wall off a driveway. Joint width and depth, since wider and deeper joints take more time and material. How difficult the mortar is to match. Whether brick replacement is needed where units have spalled through. And whether water-source correction is part of the scope. We assess it on site, price the scope, and put exclusions in writing.
