ᐅ Screed too low. Are there standards or regulations for this?

Hello,

I am currently having a disagreement with my screed installer. I have installed vinyl flooring throughout my entire house. Now I have noticed that the door threshold at the main entrance is much too high, as well as those at the patio doors. Additionally, the interior doors are supposed to be installed now, but they do not fit. The trims do not cover the lintel above the doors. The screed installer is saying that he assumed tiles would be laid in the house, and that’s why he kept the screed level so low. Are there any standards or regulations regarding this? Thanks

What assumptions did he have to make? What does the building specification say? For tiles, the level must be lower, just look at how thick they often are compared to the much thinner PVC. Karsten

Hello, there was no detailed construction description regarding the screed. I took the painting and floor installation work from the general contractor's offer. It also did not specify which type of floor covering would be installed.

It is not uncommon that the craftsmen receive no detailed drawings for the floor construction, showing the layer composition in millimeters (mm) and specifying the materials used. Instead, the drawings only indicate the finished floor level or provide an overall thickness to work with. In such cases, the craftsman relies on their experience to leave enough space for the build-up. Especially if, for example, tiles were shown in the drawing but you install vinyl instead without informing them, their approach was exactly correct. Imagine if it were the other way around—what problems it would cause if the patio doors scraped over the tiles when opened.

Aha. Communication problem. Everyone assumes their own part and does what they think is right, instead of saying what should be done.
And now? I don’t know either.

Unless otherwise specified or agreed upon, a buildup of 1 cm (0.4 inches) is assumed, which corresponds roughly to a standard tile thickness. If you removed this layer at that position, you should have informed the builder or screed installer. -> Note: screed is spelled without a “t” 😉

Regarding the door "edges" (top or bottom?) or the covering of the lintels, I have some questions… don’t these contradict each other?

In any case, the length of the door frames should normally be adjusted individually on site.
