View detailsLocal knowledge
What we see in Markham homes
Heritage masonry in Unionville and along Main Street needs soft lime-based mortar. Repointing older Markham brick with a modern hard mortar traps moisture and spalls the brick face — matching mortar strength is not cosmetic, it is structural.
That kind of pattern is why we do not quote Markham work over the phone. A ten-minute diagnostic on site routinely changes the recommendation — and often lowers the price.
