ᐅ Crack in Oak Wood Stair Landing Shortly After Installation

Hello,

a layman's question:

I have a newly built staircase in a new construction (wooden steps and landing on a concrete staircase. Oak – 45mm (1.8 inches) thick). After a few weeks, the stair landing has cracked. The crack is right along the glued joint (lengthwise), about 30cm (12 inches) long. So my question is: can this happen, or is it considered a defect if the glue joint essentially fails?

Yes, that can happen, as you can see. However, this clearly seems to be a defect; a photo could help with the assessment. But if the staircase is only a few weeks old, this should definitely not occur and likely indicates post-drying of the wood. Wood naturally moves over time, but it should of course not crack or have the glue joints come apart.

Of course, there are often good reasons why photos aren’t possible, but if it’s feasible...
I believe this cannot be emphasized enough.
