Downtown Elmhurst is unusual in DuPage County, and it creates an unusual diagnostic problem. Walk from the Metra station out along York Road and Schiller Street and you pass, sometimes in the same block, century-old two- and three-storey commercial buildings and mixed-use podium buildings put up between roughly 2005 and 2020 — retail or restaurant at grade, condominiums or apartments above, five or six storeys, brick-clad.

Those two buildings share a street and share nothing else. And the newer one is frequently in worse shape.

A 1910 commercial building fails slowly, from the joints, in ways a mason has seen a thousand times. A 2010 mixed-use building fails from its sealant and its flashing, faster than anyone budgeted for, and the symptoms show up several floors away from the cause.

Why the newer buildings are failing first

This surprises owners and boards constantly, and there is a straightforward explanation.

An old solid masonry wall is massive. It resists water by absorbing it and drying out again, and its weak point — the mortar joint — is replaceable and lasts decades.

A modern veneer wall is thin and drained. It is a single wythe of brick, or a thin adhered brick finish, over an air gap and a steel stud or block backup, and it depends for its weather resistance on a set of components with far shorter service lives:

• Sealant joints at windows, doors, material transitions and movement joints — typically fifteen to twenty years
• Through-wall flashing and weep holes, which only work if they were installed correctly and remain open
• Shelf angles at each floor line, carrying the veneer's weight
• Wall ties, holding the veneer to the backup
• Window-perimeter details at a very large number of openings

Every one of those is a discrete component with a finite life, and on a building completed in one season they all reach the end of that life at roughly the same time. That is why a fifteen-year-old Elmhurst mixed-use building can start leaking in four places in one spring.

The four conditions we find on podium and mid-rise stock

1. Window-perimeter sealant

The largest single length of sealant on the building, at the most exposed junction, on the component most likely to be blamed last. When it goes, water enters at the head and jambs and runs inside the wall.

2. Horizontal cracking at a floor line

A level crack at a consistent height is usually the shelf angle corroding and rust-jacking the course above it — not settlement. Rust occupies more volume than the steel it came from, so it lifts masonry. The repair reaches the steel, which means taking courses down. Brick veneer ties, shelf angles and hidden steel covers how to read it.

3. Blocked or absent drainage

Weep holes mortared shut by a prior repointing crew, buried behind raised planters, or never provided. Through-wall flashing omitted or unlapped at floor lines. A drained wall with its drainage closed stops being a drained wall. See weep holes and through-wall flashing.

4. Thin adhered brick mistaken for veneer

Some newer façades here are not brick veneer at all but a thin adhered brick finish bonded to a substrate. It fails by debonding and substrate moisture rather than by joint deterioration, and repointing it accomplishes nothing. Establishing which system is on the wall is the first thing we do. Manufactured stone veneer failure covers the closely related adhered-finish problem.

Old building, new building — two different scopes

| | Pre-1940 commercial | 2005–2020 mixed-use | |---|---|---| | Wall type | Solid masonry, soft brick, lime-rich mortar | Drained veneer over steel stud or block | | Primary failure | Mortar joints at end of service life | Sealant, flashing, shelf angles | | Mortar rule | Mix must be softer than the brick | Match existing; the joint is not the water barrier | | Where the leak enters | Joints, sills, parapet, cornice | Window perimeters, floor lines, transitions | | Where it appears | Near the entry point | Often floors below and bays across | | Wrong move | Hard Portland-heavy repointing | Repointing instead of re-detailing sealant and flashing |

On the older downtown buildings the governing rule still holds: the mortar must be softer than the brick it holds, so movement and moisture relieve through the replaceable joint rather than spalling the brick face. Lime versus Portland mortar covers why, and solid masonry versus brick veneer repair covers the distinction that decides the whole scope.

Tracing the leak, not the stain

On a podium building the reported leak location is rarely useful on its own. Water entering at a fourth-floor window head lands on the first obstruction it meets — a flashing edge, a shelf angle, a steel member — and exits there, which may be two floors down and a bay to one side.

So our assessment works upward and outward from the stain, not at it: water-testing where appropriate, checking the window heads and jambs above, opening a weep condition, checking the flashing lap at the nearest floor line, and reading the crack pattern for steel. Repairing the nearest visible defect is the reason these leaks survive two or three contractors.

Working on an occupied mixed-use building

This building type has the most demanding logistics in commercial masonry: retail and restaurants at grade that cannot lose their frontage, residents above who need notice and quiet hours, a public sidewalk directly beneath the work, and often a shared garage or podium deck below.

Masonry work in occupied buildings covers the communication discipline; who signs off — approval chains on commercial masonry matters when a commercial owner and a residential board share one façade.
