At Least Three Townhouse Basements Flooded in One Morning

I was drinking my coffee and watching the rain come down hard enough to flood the street when the first basement call came in. The old townhouses are always on my mind during weather like that. Water has a way of finding the weak spot nobody noticed during the last dry week.

By the time I reached the office, several tenants had called. My maintenance guy was already checking the buildings. Our custodian was helping with cleanup. I stayed on the phone long enough to get the basic picture, then tried to keep track of which basements were affected.

I am leaving tenant names and unit details out of this. The useful part is what caused the flooding and what we did next.

At least three basements changed the day

Around noon, water was coming into at least three townhouse basements. At that point it was not one resident's leak. We had a site problem.

My maintenance guy tried to trace where the water was coming from while I moved between calls and the affected buildings. Everyone was frustrated. The residents wanted the water stopped. Staff were trying to clean while more water was still finding its way in. I was trying to work out which vendor we needed first.

The plumber arrived and checked the drainage and waterproofing. He found a plugged drainage point near the playground. Water had backed up instead of moving away from the townhouse row, and the basements took the hit.

The old waterproofing did not help. In some areas it was barely doing anything. Clearing the drain dealt with the immediate backup, but it did not make the foundations younger or seal every place water could enter.

Cleanup was only the first part

Once the drainage started moving again, we could get ahead of the standing water. Our custodian helped with cleanup while my maintenance guy kept checking the source of the problem. I kept residents updated and started a list of follow-up calls.

A wet basement can look better quickly after the visible water is removed. That does not mean the work is finished. Damp materials can stay wet after the floor looks dry, and mould is exactly the kind of second problem that shows up after everyone relaxes.

I had already written about how a mould problem grows when moisture is left alone. That was in the back of my mind while we were cleaning. We needed to watch the affected areas, not assume the problem was over because the puddles were gone.

I also had to be careful about promises. I could tell tenants the drain had been cleared and the water was being cleaned. I could not promise what a waterproofing company would find or when a larger repair would be approved. People deserve an honest update, even when the honest update is that another assessment still has to happen.

The work order stayed open

I created a work order for a waterproofing company and sent it out for follow-up. By the end of the day, I was still waiting to hear back.

That waiting period is frustrating because the emergency feels finished from the outside. The rain slows down. The floor gets cleaned. The phone stops ringing every five minutes. Meanwhile, the cause that made the flooding worse is still sitting behind an old wall or below grade.

The next visit needed to look beyond the plugged drain. We needed someone qualified to assess the waterproofing and tell us what repair was actually required. Until that happened, I was not comfortable pretending the townhouses were sorted out.

The playground drainage also needed more attention during heavy rain. Finding one blockage tells you where to look the next time the forecast turns bad. It does not guarantee the same spot is the only risk, but it gives staff one more thing to check before water reaches a basement.

After the rain

By the end of the shift, the immediate water had been cleaned and the drain was working again. That was the good part.

The rest was still open: checking the affected basements, watching for moisture, following up with the waterproofing company, and keeping residents informed. The blocked drain had been cleared, but we were still waiting to learn what the waterproofing company would recommend.

It had been a long day, and I was looking forward to a quiet evening. The visible water was gone, but the follow-up work was not finished.
