Waterloo Region • In-house crews
Parging is not paint. In Preston, Cambridge it is the sacrificial coat that keeps freeze-thaw out of the block. We repair the masonry, then parge — not the other way around.
Foundation Masonry — no obligation
Cambridge does not fail foundations in theory. It fails them with river-valley silt and clay in Galt, Preston, and Hespeler with sandier pockets on the plateaus. Mill-era stone and brick along the Grand plus post-war bungalows and 1990s subdivisions. When we repair foundation masonry and parging here, we design for that — not a generic “Southern Ontario” brochure.
Preston’s older lots along the Speed need both masonry repair and a real drainage plan.
We still treat this as a Cambridge job: same crews, same warranty, but we show up already knowing how Preston lots drain (or don’t).
Free inspection. Photos. A number. No hard close.
Water in the face of the block freezes. The face pops off. More water gets in. Repeat every March. In Preston, Cambridge, that plays out against river-valley silt and clay in Galt, Preston, and Hespeler with sandier pockets on the plateaus.
Soft, sandy joints wick water. Repointing with the right mix (not bagged grey that is harder than the brick) is the job. In Preston, Cambridge, that plays out against river-valley silt and clay in Galt, Preston, and Hespeler with sandier pockets on the plateaus.
Skim-coating a wet wall traps moisture. We find why it is wet first. In Preston, Cambridge, that plays out against river-valley silt and clay in Galt, Preston, and Hespeler with sandier pockets on the plateaus.
Hammer tap, look for hollow parging, rusted lintels, and stair-step cracks that are structural not cosmetic.
Replace spalled block, repoint joints, repair brick at grade.
New parging on a prepared wall, or breathable repair on heritage brick that should not be coated.
Grade, eaves, and membranes still matter. Pretty masonry on a swamp fails.
Colour and texture that belongs on a ${p} street, not a grey smear.

Not by itself. It is a warning that water is winning. The block behind it might be.
We source close matches. Perfect 1920s brick is rare; honest blend is the goal.
On a dry, prepped wall, many years. On a leaking wall, until next winter.
Our focus is foundation and below-grade masonry. We will tell you if a mason who does chimneys is the better call.
Cosmetic parging usually not. Structural block replacement sometimes yes. We flag it.
We typically reply the same business day.
