Mid-Century Brick Ranch Masonry Repair: Roman Brick, Breeze Block, Planters and Long Window Walls

Mid-century brick ranch masonry repair in the Chicago suburbs usually starts at five places: the long steel lintels over picture windows, brick planters built against the house, stack-bond and Roman brick panels, breeze block screens, and the low, wide chimney. These houses were built in the 1950s and 1960s, so they are now 60 to 70 years old, and their masonry has some weak points that newer and older homes do not share. Emerald Masonry LLC repairs ranch homes across Chicagoland and matches the long, thin brick and mortar colours that give them their look. For a free on-site assessment, call (708) 288-1696.

On a mid-century ranch, the masonry problems are usually horizontal: long window openings, long low walls and long planters. That is where the movement, rust and water collect.

The brick ranch is one of the most common houses in the Chicago suburbs. You find whole neighbourhoods of them in Oak Lawn, Burbank, Evergreen Park, Elmhurst, Downers Grove, Park Ridge, Des Plaines and dozens of other towns, as well as on the city's far southwest and northwest sides. Some are plain post-war ranches; others have strong mid-century modern details. This guide covers both.

How a mid-century brick ranch is built

Most 1950s and 1960s ranches are brick veneer over wood framing, sitting on a concrete block or poured foundation, often with a basement or crawl space. The brick is a single layer, held to the framing with metal ties, with an air space and, in theory, weep holes at the bottom to drain water. Many houses of this era were built with few weeps or flashing that has since failed.

The mid-century details

What makes these houses different is the detailing:

• Roman brick: a long, thin brick that emphasises horizontal lines.
• Stack bond: decorative panels where bricks are stacked directly on top of each other instead of overlapping.
• Long picture windows and window walls, with steel lintels spanning wide openings.
• Brick planters built along the front of the house, often tied right into the wall.
• Breeze block: decorative concrete screen block for patios, carports and entries.
• Lannon stone or other stone accents on chimneys, planters and front walls.
• A low, wide chimney, often with a broad face toward the street.
• Wide roof overhangs, which actually protect most of the wall from rain.

Causes and warning signs of masonry problems on ranch homes

Rusting lintels over picture windows

Wide openings need long steel lintels. After 60 years, many are rusting. Rust expands, pushing the brick above, and the signs are horizontal cracks along the lintel line, step cracks rising from the window corners, rust stains and, in bad cases, a visible sag in the brick over the window.

Planters against the house

A brick planter tied to the front wall keeps wet soil against the house all year. Look for spalled or crumbling brick inside and below the planter, efflorescence, cracks where the planter meets the wall, bulging planter walls, and basement leaks behind the planter.

Stack bond and Roman brick panels

Stack bond has continuous vertical joints, so it is weaker than ordinary running bond. Look for cracks running straight down the vertical joints. Roman brick walls show the same mortar problems as other brick, but matching replacement units is harder.

Breeze block screens

Decorative screen block can crack, lose mortar and loosen at its anchors to the house or slab. Look for broken units, open joints and screens that move when pushed.

The chimney

Even a low chimney is exposed above the roof. Look for open joints, a cracked crown, loose top bricks and stains on the ceiling near the chimney.

Lower courses, garage piers and walks

Driveways, walks and salt sit right against the bottom of many ranch walls. Look for spalled brick low on the wall, cracked garage door piers and eroded joints near the ground.

Weeps and flashing

If weep holes are missing or buried under landscaping, water in the wall has no way out. Look for staining and efflorescence low on the wall and rot at the bottom of the framing.

Lannon stone accents

Many ranches have Lannon stone, a light, layered stone quarried in Wisconsin, on the chimney, planters or a feature wall. Its joints are wide and irregular, and the mortar in them erodes faster than in the brick around it. Look for open or missing joints, loose stones at the top of a planter or chimney, and stone faces splitting along their layers.

Glass block windows

Basement and bathroom openings on ranches often have glass block. The mortar around and between the blocks cracks, the perimeter joint to the brick opens, and water gets into the wall or basement. Look for cracked blocks, open joints and stains below the panel.

What to fix first on a mid-century ranch

Most ranch owners cannot do everything at once. This is the order we usually recommend:

| Priority | Issue | Why | |---|---|---| | 1 | Loose brick, a sagging lintel or a loose chimney top | Safety: masonry that can fall | | 2 | Water getting in: planters, failed sills, open joints at the base | Water damage spreads fast inside | | 3 | Rusting lintels before they sag | Clean and coat now, or replace later | | 4 | Chimney crown and top joints | The most exposed masonry on the house | | 5 | Tuckpointing worn walls | Prevents spalled brick | | 6 | Cosmetic repairs and old mismatched patches | Appearance, once the house is sound |

We put this order in writing, with prices for each item, so you can plan repairs over more than one season.

How a professional repairs a mid-century ranch

1. Walk the whole house. We check every elevation, the chimney, openings, planters and screens, and list what needs work now and what can wait.
2. Find the water first. Gutters, downspouts, grade, planters and weeps, so repairs are not undone by the next storm.
3. Repair lintels over large openings. Remove the brick above, clean and prime or replace the steel, add flashing and end dams, and rebuild the brick with matched units.
4. Rebuild or separate planters with drainage and a liner, or remove them and repair the wall behind.
5. Repoint eroded joints with mortar matched in colour, tooled to the original profile.
6. Replace damaged brick with matched Roman or standard brick, salvaged where needed.
7. Repair stack-bond panels, adding joint reinforcement where the panel has moved.
8. Repair or reset breeze block screens with proper anchors.
9. Repair the chimney with repointing, a new crown or a partial rebuild.
10. Open or add weeps at the base of the wall where they are missing or blocked.

Materials and techniques for mid-century masonry

| Item | What we use | Why | |---|---|---| | Mortar | Type N, colour matched | Suits the brick of this era; colour drives the look | | Roman brick | Current Roman-size, salvaged or borrowed units | Standard brick is the wrong size | | Steel lintels | Galvanized or primed and coated steel with flashing | Stops rust jacking and drains water out | | Stack-bond repair | Joint reinforcement where needed | Compensates for the weak vertical joints | | Planters | Liner, drainage, separation from the wall | Keeps soil water off the house | | Breeze block | Matching pattern, reset with anchors | Keeps screens stable | | Water repellent | Breathable siloxane only where needed | Film-forming sealers trap water |

Matching Roman brick and mid-century mortar

Mid-century homes often used distinctive brick colours and mortar colours, from tan and buff to dark iron-spot brick with raked or flush joints. A repair that uses standard-size brick, or grey mortar where the original was tan, stands out immediately. We match size first, then colour and texture, then the mortar colour and joint profile. Our guide to brick matching for replacement explains how that process works.

Steel lintels on long spans

Long lintels are the most important structural repair on most ranches. A lintel that is cleaned and coated in time can last for decades more; one left until the brick sags usually needs full replacement. See orange rust streaks from lintels for the early warning signs.

What drives the cost of mid-century ranch masonry repair

• Lintel work over picture windows and garage doors: clean and coat, or replace.
• Planters: repair, rebuild with drainage, or removal and wall repair.
• Tuckpointing area and joint depth.
• Brick matching, especially for Roman or specialty brick.
• Chimney repointing, crown or rebuild.
• Breeze block and stone repairs.
• Access around landscaping, patios and carports.

Most ranches are one storey, so access is easier than on a two-storey home, but specialty brick matching and lintel work can still drive cost. Emerald Masonry LLC gives a written, itemized estimate after a free on-site assessment.

DIY vs hiring a pro on a ranch home

Homeowners can safely keep gutters and downspouts working, keep soil and mulch below the weep holes, trim plants back from the walls and watch for new cracks. Lintel repair, brick replacement, tuckpointing and chimney work are best left to a mason. Lintel work involves temporarily supporting the brick above an opening. Matching Roman brick and mortar colour takes sourcing and experience. And patching cracks over a rusting lintel with caulk or mortar only hides the problem until it gets worse.

The Chicago context: why ranches age the way they do

Chicago's freeze-thaw winters work on every joint and brick face that stays wet. On a ranch, the wide roof overhangs protect most of the wall, so the damage concentrates where water is not shed: under planters, at the base of walls near driveways and walks, around window openings and on the chimney. Road salt from driveways and streets adds to the damage on low brick. After 60-plus years, many original steel lintels have reached the point where rust is visible.

If your house is a raised ranch or split-level rather than a single-storey ranch, see our raised ranch and split-level guide, which covers the exposed lower levels those houses add.

Maintenance and prevention for brick ranch homes

• Look at your window and garage door lintels each spring for rust, cracks or sag.
• Clean gutters and keep downspouts draining away from the house and planters.
• Keep mulch and soil below the weep holes and away from the brick.
• Check planters for bulging, cracks and wet brick.
• Look at the chimney each year for open joints and crown cracks.
• Rinse salt off low brick near the driveway in spring.

The bottom line on mid-century brick ranch masonry repair

On a 1950s or 1960s brick ranch, check the lintels over the big windows first, then the planters, the chimney and the low brick near the driveway. Fix water problems before masonry, match Roman brick and mortar colour carefully, and do not cover cracks over rusting steel. Done well, the repairs keep the house's clean mid-century lines.
