Masonry Repairs

Brick and stone often require repair. Let us handle it properly!

Tuck Pointing or Repointing
Tuck pointing is the removal of old mortar to a minimum depth of 5/8 of an inch. The mortar joint area is replaced with new mortar with a preferred concave joint. Concave joints are considered the least susceptible to water penetration. We try to achieve the best possible colour match to the existing mortar joints and type of mortar joint finish.

Brick Spalling Repairs
Deterioration, or spalling as it is referred to in our industry, is an indication that water is penetrating and causing damage. Spalling of bricks can occur at various locations around your home. Brick, stone or block installed too close to grade level (too low to the ground) is exposed to the environment. It should have been installed above grade level by a minimum of 8 inches. Parge should be troweled on as it resists the water, snow and salt, and protects the foundation. Another reason that brick spalling occurs is when there is no flashing or weep vents properly installed. If you can visually see the vents, they may still be plugged.

Chimney Repair
Chimney rebuilding is another common masonry repair for the GTA homeowner. Most masonry chimneys do not have issues unless they are located above the roof line. Below the roof line the chimney is protected by a roof and roof line. Above the roof line, the chimney is susceptible to many environmental exposures. It is exposed to rain, snow, wind and sudden changes of temperatures to the top of the chimney flue liner.

The hottest part of a fire is the top of the flame which is the flue liner above the roof line. When you combine a cold evening (-20 or colder) with the starting of a fireplace, the extreme change in temperature affects the top section of the flue liner, causing it to break away from the crown (if a crown exists). Our forces are trained to rebuild or repair your chimney to fire code standards including the installation of a fire rated caulking.

Window Sills
Once water penetrates, even though a small void in the mortar, it will quickly cause the deterioration to spread throughout and could possibly enter your home. Three Little Pigs Masonry recommends using 3 inch rock face Indiana limestone sills to replace brick window sills. These new sills are installed in one solid piece (up to a maximum length of 6 feet) to reduce the number of mortar joints and to give you the best overall finished product. Concrete is not recommended for window sills as it is too porous. We also install Indiana limestone sills in various thicknesses and can fulfill your customized limestone sill orders. We also provide brick repair for all brick window sills. Caulking of new sills is always included and we use commercial grade caulking for all our projects.
