Ask anyone who does masonry near me in Hinsdale what damages the most brick, and they won't say wind, salt or sun. They'll say water — specifically, water that freezes. The freeze–thaw cycle is quietly responsible for most of the deterioration we see on western-suburb homes, and once you understand how it works, you'll start spotting the risk areas around your own house.
How the damage actually happens
Brick and mortar are porous. They drink up small amounts of water from rain, snowmelt and humidity. On a mild day that water sits in the pores and eventually evaporates. But when temperatures drop below freezing, the trapped water turns to ice and expands by roughly nine percent. That expansion exerts real pressure inside the masonry, pushing the material apart from the inside.
One cycle does almost nothing. The problem is repetition. A typical Hinsdale winter doesn't stay frozen — it bounces above and below 32°F over and over, sometimes within a single day. Each thaw lets new water in; each freeze pries the material apart a little more. Over years, that's what turns a sound wall into one with crumbling joints and flaking brick faces.
Where it shows up first
- Spalling. The brick face pops or flakes off, exposing the softer interior. Once that happens the brick soaks up even more water and degrades faster.
- Eroded mortar joints. The mortar recedes and softens, opening new paths for water.
- Step cracks. Cracks that climb the joints in a staircase pattern, often near windows or foundations.
- Chimney damage. Chimneys are exposed on all sides and rarely heated, so they take freeze–thaw punishment year-round.
Freeze–thaw damage is a water management problem. Control where water goes, and you dramatically slow the deterioration — no matter how cold the winter gets.
What you can actually do about it
You can't change the weather, but you can keep water from collecting where it does harm:
- Keep gutters and downspouts clear and pointed away from the foundation. Overflowing gutters dump water straight down brick walls.
- Re-grade soil so it slopes away from the house. Splashback against the lowest courses of brick is a classic trouble spot.
- Repair failing mortar promptly — every open joint is an invitation for water.
- Be cautious with sealers. Some breathable masonry sealers help; the wrong film-forming sealer can trap moisture inside the wall and make freeze–thaw worse. Get advice before you spray anything on.
When to bring in help
If you're already seeing spalled brick or soft mortar, the cycle is well underway and a fresh assessment is worth it. A qualified mason can tell you whether you're looking at routine upkeep or something structural — and the better ones — the kind you find when you search masonry near me Hinsdale — will explain the water source, not just patch the symptom. Fixing the brick without fixing the water is how people end up paying twice.
