Your annual brick walk
Once a year — spring is ideal, after winter has done its worst — walk around your house and really look at the brick. Not a glance from the driveway; a slow walk, close enough to touch the walls. You are looking for the early warnings that separate a cheap repair from an expensive one. This ten-minute habit saves Fairfax homeowners thousands.
What to look for
Mortar condition. Scrape a joint with a key or screwdriver. Sound mortar resists; worn mortar crumbles, powders, or falls out in chunks. Look for joints receding behind the brick faces, and sandy residue piled at the wall base. Worn mortar is the most common brick problem and the most fixable — repointing renews the wall.
Spalling brick. Faces flaking, chipping, or popping off the brick. A little surface flaking on a few bricks is worth watching; widespread spalling or chunks falling means the brick is failing and needs replacement. Spalling spreads — water gets into the damaged face, freezes, and takes more.
Cracks. Hairline cracks in mortar are normal aging. Stair-step cracks running through joints — especially near corners, windows, and doors — signal movement: soil, settlement, or thermal. Horizontal cracks in a wall, or any crack you can fit a coin into, deserve a mason's assessment promptly.
Bulging or bowing. Stand at the corner and sight down the wall. Any outward curve means the brick veneer has separated from the structure behind it. This is the urgent one — bulging sections can fall. Keep clear and call a mason.
Staining. White powdery deposits (efflorescence) mean water is moving through the wall — find the water source. Rust-colored stains can indicate corroding steel lintels above windows. Green or black growth is biological — usually a moisture and shade issue, cleaned and then addressed at the source.
What can wait vs. what cannot
Can wait (but schedule): worn mortar without structural symptoms, minor spalling on a few bricks, hairline cracks, cosmetic staining. These are maintenance items — plan them for the next suitable season.
Cannot wait: bulging sections, growing cracks, bricks falling from height (chimneys, tall walls), water actively entering the house. These are safety or active-damage issues. Call promptly.
What to do when you find something
Document it — photos with dates, so you can tell if it is changing. Do not caulk large mortar gaps or smear cement over problems; wrong-material quick fixes make professional repair harder and more expensive. Then call a mason for an assessment. Our estimates are free, and we will tell you honestly what needs doing now, what can wait, and what is just cosmetic.
