Is your chimney safe

The storms last winter caused extensive flooding and structural damage to homes and businesses, but now after enjoying a long summer with unusually warm, sunny days and low rainfall, this is all but a distant memory for many.  So are we in for another battering this winter?  That we can’t be sure, but we do know that roofs and chimneys are not going to withstand the force of extreme weather unless they are well-maintained with any repairs being undertaken properly. 

Chimneys perform many vital functions but despite this, they are often neglected and over-looked during general maintenance checks.  Regular chimney maintenance is essential to prevent damage and deterioration.  If left un-checked a chimney can be a serious health and safety hazard.

How to prevent further water damage

Chimney caps are a preventative measure that will help stop water penetration, and they will also prevent birds and animals from entering or nesting in the chimney.  

Check Chimney Crown – this is the top element of a masonry chimney and acts to direct water away from the flue to the edge of the crown.  This should be crack-free and extend beyond the sides of the chimney a minimum of two inches.

Repair Joints – deteriorated mortar is an entry point for water.  Re-pointing will seal the joints and give the chimney a longer lifespan.

Repair/Replace Flashing – If you are seeing water damage in ceilings or walls, the chimney flashing may need repairing or replacing. This forms a seal between the roof and the chimney and prevents rainwater from running down the chimney into living spaces.
