Chimney Repair

Is your chimney cap cracked? Are the faces of the brick falling apart? Is mortar missing between the bricks?

These are all good indications that your chimney needs repair.

The Ottawa weather is especially hard on chimneys, due to the effect of seasonal freezing and thawing. Depending upon the degree of deterioration, there are different types of chimney repairs available.

Canadian Masonry Services’ qualified technicians evaluate the condition of the chimney and advise you on the best chimney repair solution.

10 Year Warranty on all Chimney Caps

Most Chimney Repairs are a Result of Improper Chimney Cap Construction

Deterioration of the chimney cap can be attributed to weathering and inappropriate seals between the flashing and the chimney. Regular inspections will save you thousands of dollars in chimney repairs. The difference between traditional masonry caps and metal caps have been a point of contention in recent years.The Ontario building code (Section 9.21.4.6.2) is clear on two facts:

  • The chimney cap must be sloped from the chimney lining to the edge,
  • and the chimney cap must provide a drip edge.

This is not the case with metal caps generally produced in the Ottawa region. There are a few exceptions with custom copper or aluminum caps made on site. These metal chimney caps can be made to meet the Ontario Building Code. Flat tin chimney caps do not meet the Ontario Building Code. The joints are soldered, not folded and the craftsman create a ribbed fold to provide proper rigidity and protection. Custom made caps on site are very expensive and not suited for the general home owner.

As a result, Canadian Masonry Services will not install metal chimney caps. Canadian Masonry Services constructs new, sloped, stone chimney caps, with a drip edge and a 2″ waterproof concrete weathering cap. All of our chimney caps are coated with an elastomeric compound. Our chimney caps meet the Ontario Building Code for chimney caps (Section 9.21.4.6) and as such carry a ten year warranty.Our caps are made of precast concrete stones that carry a drip edge over the stone. We create a weathering cap or (wash). This serves two purposes;

  1. The upward slope drains any precipitation from the lining to the edge of the chimney cap and
  2. The slope deflects the air current to accentuate the draft.

We separate the chimney liner from the cap with a compressible material to break the bond at the contact point between the chimney lining and the concrete cap. A bead of sealant is applied at this point.

Finally to maximize the chimney services we resurface the crown of the chimney with additional fast setting elastomeric compound. Elastomeric compound is a coating that forms a flexible waterproof membrane that remains flexible in cold weather.

Only Canadian Masonry Services goes the extra mile to ensure that you will get decades of service and freedom from your chimney repair. We also have the best warranty in the Ottawa region.
