Water leakage at the patio

[erik8308]

Hello,

We have a two-year-old extension with 2 floors, one part of which on the upper floor is a terrace. Now, with all the snow, water has started leaking down to the floor below. It has been running along one wall.
A bit of snow has been standing against the terrace doors, but isn't it unreasonable for a significant amount of water to leak in? In the room, about a deciliter has come in, but then it has made its way through the floor structure and wall (about 1 meter).

I have contacted the builders, and they are coming for a visit next week, but I wanted to check here about the reasonableness of this. Sure, you can shovel, but if you go away over Christmas and New Year's and it snows a lot, you shouldn't have to worry about water seeping into the structure, right?

Thanks in advance

Hi, a few questions to draw some conclusions here

had some snow against the patio doors on the terrace

Is the door inward-opening?

In the room, it has probably only come in a deciliter

Is it the room that the patio door is in, and when you estimate the amount to be a deciliter, is it liquid on the floor?
Is the liquid closest to the patio door?

Is the room with the patio door where you estimate the amount to be a deciliter, is there liquid on the floor?

The door opens outward. No, the liquid has reached the floor below. So it has leaked through the beams without appearing in any visible way on the upper floor. There are no traces of liquid on the inside of the door.

There are no traces of liquid on the inside of the door.

hmm ... it almost feels like this might not be related to the snow ...
You don't have any water pipes in that wall that might have frozen and burst, or if it's a new construction, a carpenter who has accidentally drilled into a pipe?

Hmm, what makes you think it's not? No carpenter has been here for 2 years.

There are a couple of heating pipes nearby, but they shouldn't freeze.

what makes you think it's not

Just speculating that you might have a "slow puncture" in a water pipe ... You need someone on site who can seriously check it out, water leaks can be super hard to trace

Mysterious are the ways of water as it says in the carpenter's bible ;-)
