Do you live in Mississauga or Oakville and your chimney is “weeping”? Before you tear it down, check the grout! Many homeowners panic when they see crumbling joints or moisture on their chimney. Their first thought? “It needs to be rebuilt.” Stop! In most cases, professional grouting is all that is needed to save the structure and thousands of dollars in your wallet.
When does a chimney need saving?
A chimney above the roof is exposed to the harshest conditions: rain, frost, and huge temperature differences. Over time, the mortar washes out and crumbles, opening the way for water. If you notice: empty spaces between bricks, moisture penetrating the interior of the building, loose individual bricks, it's a sign that it's time to take action. But don't worry – “action” does not necessarily mean a team with pickaxes.
Why is grouting the best solution?
Huge savings: Rebuilding a chimney costs several thousand dollars (materials, labor, scaffolding, debris disposal). Repairing the joints alone costs a fraction of that amount. No demolition: The work is limited to the outside of the chimney. You avoid mess in your home, dust, and the risk of damaging the roof covering during demolition. Instant results: Professional joint filling and possible clinker impregnation restore tightness in one day.
How to do it right?
Instead of rebuilding, opt for renovation: Cleaning the joints: Remove loose, weathered mortar to a depth of approx. 1.5–2 cm. Suitable mortar: The key is to use mortar that is resistant to frost and high temperatures, preferably with the addition of trass (prevents efflorescence). Watertightness from above: It is often enough to repair the chimney cap to prevent water from pouring into the wall structure. Summary Don't be persuaded to undertake a costly reconstruction if the chimney structure is stable. Often the problem is not a “bad chimney” but simply “worn mortar.” Invest in proper sealing – your chimney will regain its tightness and you will save money for other household expenses.
