Defect?? Glued engineered parquet doesn’t stick everywhere?!

Hello questioner. For us professionals, it is sometimes not difficult to look into the near future. The adhesive supplier may come to the conclusion that the subfloor pretreatment (before the parquet installation) was defective. Otherwise, there is no reason for the adhesive to detach through adhesion failure from a substrate (screed) that has already been used, along with its auxiliary layers (primer/filler). Then it will be necessary to consider whether, in view of the already detached areas and those that may still detach in the near future, a reinstallation with prior new pretreatment of the installation surface might be the safer option for you. Through the upcoming visit of the representative of the adhesive supplier, you can later prove that there were problems with the parquet installation. Only for purposes of later proof, I had recommended that you formulate the Mängelrüge in writing. So let's wait and see how first the field service employee of the adhesive supplier and then the installer will comment on the matter. My guess is that you may well remember these threads in this forum both vividly and painfully in the future. I write this from experience..... ------------------------- I hope the best for you, Kind regards: KlaRa

We reported the defect immediately (verbally)

Sigh..... I really wonder why so many diligent helpers provide their knowledge free of charge here, if apparently nobody takes it to heart. A notice of defect, as my predecessor rightly emphasized _several times_, must be made _in writing_. I hope for you that KlaRa's suspicions will not prove true; however, I can understand them well.

Well, the complaint about defects can already be sufficiently proven by the visit of the floor layer, who cut out a piece of parquet, and the involvement of the adhesive manufacturer.

The "written complaint about defects" is of course always better because it specifies the content of the complaint. But writing alone is not enough, as receipt must be proven. If done correctly, then by registered mail with return receipt or courier with proof of receipt.

I would always proceed by calling or sending an email. If there is then no immediate reaction or a delay is noticeable, I would in any case notify in writing (as described above).

I agree with Voki as well. When the parquet installer reacts immediately like ours did and was already here the next day, even having ordered new parquet for us, it is no longer strictly necessary to report it in writing. He has now been here twice and has cut out the loose spots everywhere and looked at the adhesive.

The screed was sanded and then treated with a primer (thick, like honey, but hard after drying). After that, the parquet was glued onto it.
Of course, it could also have been the wrong primer for the adhesive. But I obviously cannot judge that. We even specifically hired a professional company so that the floor would be installed professionally.

A complaint about defects, as my predecessor correctly emphasized _several times_, must be made _in writing_. I hope for you that KlaRa’s suspicions do not turn out to be true; however, I can well understand them.

For the first step, I also do not see a problem - from experience - in reporting a defect verbally. Even after months of house construction, an email or a call to the site manager, then an attachment of a photo, is enough and the craftsman is on the hook.
And if no response is received within 10 days, a written complaint about defects can be made. Because it is not waived just because one uses a quick way... only one should certainly create a record for themselves and for later (in case of need) in which the corresponding correspondence is documented.

Good day,

I almost believe that you think that a complaint about defects is something terrible for a craftsman. No, it is by no means. Sending a complaint about defects with an exact description of the defect – and here Volker is of course right, it must be done via ERSch, in any case provable – is a completely normal business process. As a rule, all craftsmen react quickly to it and strive to eliminate the defect; the TE, as well as Yvonne, have confirmed this.

However, it is the case that not every client concludes a contract according to the Building Code; many are also based on the VOB, especially construction-related trades, such as flooring or painting work. These trades are often awarded only after the actual construction contract for the house has been completed; the contractors are searched for and commissioned by the client themselves. Unlike with a Building Code contract, where a defect does not suspend the statute of limitations, the contract according to VOB actually provides for an interruption of the limitation period. This means that the current four-year warranty period is interrupted until the defect is remedied and then begins anew. The time of the interruption can only be proven beyond doubt if the defect is described in words and pictures and a complaint about defects has been sent.
