How Do Chimneys Hold Up in Algonquin’s Weather?
Algonquin’s climate is tough on brick and mortar. Constant freeze/thaw cycles expand tiny cracks into major damage within months. Even one brutal winter can accelerate decay if the chimney isn’t sealed or properly capped.
- Water seeping into mortar joints freezes and expands, causing crumbling or spalling.
- Meltwater leaks through flashing, damaging ceilings and walls.
- High winds and hail can loosen chimney caps or flashing, leading to structural gaps.
- Soot and creosote buildup attract moisture, which worsens interior deterioration.
That’s why we always recommend a spring inspection and a fall tune-up. Catching small issues early, like minor mortar gaps or hairline crown cracks, can save thousands in structural repairs later.
What Should You Do Before Using a Chimney After a Storm or Flood?
It’s tempting to light a fire on the first chilly night after a long summer, but if your chimney’s been through a heavy storm or flood, it’s worth pausing first. Water infiltration can dislodge bricks, rust dampers, and saturate liners. We often tell homeowners: if it’s been wet, get it checked.
- Our team inspects for hidden cracks or warped metal components.
- We test draft flow to ensure safe venting before lighting up.
- We clean out debris from wind or rain, including leaves, nests, and blockages.
- We reseal vulnerable joints or waterproof the masonry to prevent future damage.
After a major storm season, even if you don’t see visible damage, moisture trapped inside the flue can cause serious long-term issues.
How Fast Can Crumbling Mortar Compromise Chimney Stability?
Faster than you’d expect. In just one season, moisture and freezing can turn soft mortar to powder. That’s why we perform precision tuckpointing, replacing only the damaged mortar and matching it perfectly to the original. This restores strength without changing your chimney’s look.
- Mortar deterioration opens pathways for water, weakening the brick structure.
- A leaning or cracked chimney is more than an eyesore… It’s a potential collapse risk.
- Unsealed crowns or missing caps accelerate decay from the top down.
- Waterproofing and timely repointing extend the lifespan of your masonry dramatically.
If you notice white powdery stains (efflorescence) or bits of mortar collecting on the roof, that’s your first warning sign to call us.
Can We Prevent Future Damage?
Absolutely. Prevention is our favorite kind of repair. Every chimney we service in Algonquin gets a thorough moisture inspection. We apply breathable waterproofing products designed for Illinois’ freeze/thaw climate and install stainless steel caps and flashing that can outlast the roof itself.
- Annual inspections catch cracks before they expand.
- Chimney caps block rain, leaves, and critters.
- Proper flashing seals out roof runoff.
- Waterproofing keeps your masonry dry without trapping vapor.
We always say chimney protection is cheaper than chimney repair.
