Water Damage Restoration in Unionville

Unionville rewards a restoration company that slows down. In a subdivision built in 2015, a technician can be confident about what is behind a wall before opening it: standard stud spacing, poly vapour barrier, batt insulation, half-inch drywall. In a house on Main Street built in the 1860s or 1870s, what is behind the wall might be wood lath and lime plaster, an early layer of beaverboard, a mid-century panelling job, and a 1990s drywall skim, all stacked on top of one another. Each of those layers holds and releases water at a different rate, and a moisture meter reading taken at the surface can be badly misleading. Our technicians take readings at multiple depths and in multiple materials, and we open the smallest inspection area that will answer the question rather than the largest.

The second thing heritage work demands is restraint with heat. The instinct in structural drying is to raise temperature and airflow to accelerate evaporation, and in modern construction that is exactly right. In a nineteenth-century house it can destroy the very thing the owner is paying to protect. Softwood plank subfloors cup and split. Lime plaster separates from lath and detaches in sheets. Original softwood baseboard, casing and stair parts shrink and open at the joints. We manage these projects with lower temperatures, controlled airflow directed at the wet assembly rather than the room, and dehumidification that removes the moisture we release, tracking the daily rate of change so drying proceeds steadily instead of violently.

The stone foundation question comes up on almost every historic Unionville job, and it deserves a direct answer. A fieldstone or rubble foundation laid without a damp-proof course is permeable by design. It was intended to let moisture move through the masonry and evaporate into an unfinished, ventilated cellar. When an owner in the 1990s framed that wall, stapled poly to the studs and hung drywall, the evaporation path closed. Moisture then accumulates in the stud bay, the back of the drywall, and the insulation, out of sight and out of airflow, which is a textbook environment for mold growth. When we find that condition during a water loss, we say so, because restoring the finish exactly as it was guarantees a repeat visit. Remediation under IICRC S-520 with containment, negative air pressure and HEPA filtration removes what is there, and a properly detailed rebuild keeps it from coming back.

On the executive side of Unionville the problems are less exotic but the dollar values are higher. A walk-out lower level in Angus Glen or Cachet typically holds engineered hardwood, extensive millwork, a wet bar or second kitchen, built-in media equipment and sometimes a wine room, and all of it sits below grade on a lot that slopes toward a ravine or pond corridor. When a second-floor bathroom supply line fails on a Friday and runs until Sunday, water travels down through two floor assemblies and arrives in that lower level having already saturated ceilings, wall cavities and insulation on the way. The visible damage in the basement is the last chapter of the story, not the first, and treating it as the whole scope is how homeowners end up with mold in a ceiling cavity months later.

That is why every Unionville project we take begins with a documented moisture map and ends with documented dry readings, whether the house is 160 years old or 30. Between those two points we extract, dry, remediate if required, and rebuild in-house, so there is one contract, one estimator, one schedule and one warranty. Pro Max Restoration has restored more than 600 GTA properties across fifteen years, holds IICRC S-500 and S-520 certification, and bills Intact, Aviva, Desjardins, TD Insurance, Wawanesa and Co-operators directly.
