When demo uncovers more than expected
Finding mold mid-renovation doesn't have to stall the whole project
It happens more than people expect, especially in Ottawa’s older housing stock. A crew opens up a wall and finds staining or growth behind old drywall from a leak nobody knew about. A basement finishing project gets down to the foundation and uncovers moisture that’s been sitting there for years under the old paneling. A bathroom remodel pulls out an old shower pan and finds rot and mold in the subfloor around it. None of these are unusual, older homes have had decades for small leaks and condensation to do quiet damage in places nobody was looking. What matters at that point is speed: getting the affected area assessed and contained fast enough that it doesn’t hold up the rest of the renovation, and coordinating directly with your contractor so the schedule keeps moving.
Drywall removal exposes framing or insulation with staining or growth, often traced back to an old, unresolved leak.
Basement finishing
Once framing and vapor barrier go up, foundation moisture that was invisible before finishing gets discovered underneath it.
Bathroom remodels
Pulling an old shower pan or tub surround often reveals rot and mold in the subfloor that had been quietly spreading for years.
Our Process
Coordinating remediation with your renovation
1
Your contractor flags the area
Demo or framing work exposes something unexpected, and we're brought in to take a look.
2
Fast on-site assessment
We scope the affected area quickly so your contractor knows what they're dealing with.
3
Contained, isolated removal
The affected area is contained separately from the rest of the project, so finished or in-progress work isn't put at risk.
4
Sign-off to continue
Once the area is cleared, your contractor gets the go-ahead to close it back up and keep building.
Removing the mold isn't the whole job
Fixing the Mold Source Before the Wall Goes Back Up
Removing visible mold without addressing what caused it just delays the same problem until the next time someone opens that wall. Before a work zone is cleared, we try to identify what actually created the moisture, a slow plumbing leak, a missing or damaged vapor barrier, poor grading outside a foundation wall, or condensation from an unvented space. Where that source is something your contractor can address as part of the renovation, we flag it directly so it gets fixed while the wall is still open, instead of becoming a repeat call a few years down the line.
Checking for Mold Before Your Contractor Closes the Wall Back Up
Moisture source identified
Wherever possible, we flag what likely caused the mold, not just where it grew.
Affected material fully removed
Contaminated drywall, insulation, or framing is removed rather than just surface-cleaned.
Area confirmed dry
Moisture readings confirm the space is dry before anything gets closed back in.
Written sign-off provided
A written note your contractor can keep on file showing the area was cleared to proceed.
Opening up a wall, a basement, or an old bathroom in an Ottawa home sometimes uncovers more than the renovation plan accounted for.

Post-renovation mold removal questions
My contractor found mold behind a wall. What happens now?
Call and describe what was found and where. We'll typically get someone out quickly to assess the area so your contractor knows what they're working with before closing anything back up.
Will this delay my renovation?
It depends on the size of the affected area, but the goal is always to contain and clear it as fast as possible so it holds up the schedule as little as possible.
Why do older Ottawa homes turn up mold during renovations?
Decades-old plumbing, roofing, and finishes have had a lot of time to develop small, slow leaks that never got noticed until a wall or floor was opened up.
Can you work directly with my contractor's schedule?
Yes, we coordinate timing directly with your contractor so remediation fits into the renovation sequence instead of working against it.
Do I need to pause the whole project or just the affected area?
Usually just the affected area. The rest of the renovation can typically continue while the flagged zone is contained and worked on separately.
How do you protect the finished parts of my renovation from contamination?
Containment barriers and controlled airflow keep the work zone sealed off, so dust and spores from the affected area don't reach rooms that are already finished or still in progress.
