I was completely satisfied from A to Z. The pre-planned timeframe was adhered to as discussed. The quality of the windows is very good.
Always happy to come back. As a long-standing customer, I can recommend the company without hesitation.

Unfortunately, the communication between the construction site coordinator and us in the event of problems was inadequate! We also had the impression that the communication about our problems within your company did not work properly between different departments.

Advice and execution were so far good, quality OK, but customer service is rather poor. Specifically, we have made the experience twice that promises were not kept. Once with a door closer which was already defective after just under 6 months, another 6 months later, although of course there was still valid warranty, the whole thing was charged. Only after several complaints was the bill, accompanied by inappropriate comments then annulled. Another time the bill of a painting was 50% higher than the offer was. After I complained (because according to Luxembourg law, invoices may be a maximum of 15% more expensive than the offer) and I even agreed to a higher amount (I only asked for a 10% reduction as an accommodation, which would have given the company Ost Fenster even more than the offer was, this was dismissed as absolutely indisputable (Luxembourg law is therefore indisputable??). Unfortunately, I have been more than disappointed, so I could not recommend Ost Fenster with the best will in the world.

OST-Fenster Comment from OST-Fenster:
Dear Mr. Reger,
Thank you very much for taking the time to evaluate us, our products and our service.
You are satisfied with the advice, execution of the work as well as the quality of our products, but you criticize our customer service and even accuse us of not having kept our promise in directly 2 cases. We would now like to respond to these accusations and explain our point of view:
1. the door closer described by you was defective, since the door was opened over the permitted opening angle and thereby the sliding block in the rail was torn off from opening. Despite this condition, the door continued to be used, causing the opening arm, which continued to move, to permanently scrub along the slide rail, damaging it as well. Even if the door closer had only been in operation for just under 1 year at that time (not 6 months as you described!), this pattern of damage can clearly be traced back to improper operation, if not to the fact that the door was operated in a way that caused the damage. Warranty claims do not apply in such cases, and yet the work was carried out by us in an accommodating manner without charge!
2. now to the bill of the painting work complained of by you: the bill is exactly 40% higher than the offer, since not only another and thus more complex work was demanded of you, but altogether still additional achievements were furnished, which were not intended in the offer. Wishes were expressed on your part during the execution of the work and immediately implemented by us! It therefore goes without saying that in such cases the "deviation regulation" must be applied differently. And here again, we accommodated you in an accommodating manner and granted you a 3% discount as a gesture afterwards. In addition, we were very accommodating in not charging you for the colors ordered for the order but not used at your request. We could also have handed them in to you and insisted on offsetting.
We have accommodated you in both cases and therefore cannot understand your displeasure with our service. Nevertheless, we remain open to any further criticism, because only with the feedback and reprimands of our customers can we constantly improve ourselves, our products and our service.

Wir haben schon etliche Male auf die Firma OST zurückgegriffen. Das erste Mal im Jahr 2000, wo wir zwei Balkontüren und Balkonfenster ersetzen ließen, sowie ein größeres Fenster. Dann im Jahr 2001 zwei kleine Fenster, sowie der letzte Auftrag 2021/2022. Wir sind immer noch sehr zufrieden mit den Produkten, wobei mir aufgefallen ist, dass der Anstrich der Fenster mit Glasurit Farbe aus dem Jahr 2000, eine bessere sichtbare Qualität aufweist. Diese Fenster, obwohl sie dem Regen und der Sonne ausgesetzt sind, habe ich bis heute noch nie streichen müssen, dies zum Thema Material.
Was die Beratung betrifft, hier war jeder ihrer Mitarbeiter für sich ganz in Ordnung, aber wir haben den Eindruck, dass zu viele Leute im Spiel sind und daher einerseits Wünsche vom Kunden zu dem nächsten Mitarbeiter verloren gehen, oder wichtige technische Informationen zu den Fenstern an den Kunden übersprungen werden. So war es uns nicht bewusst, dass wenn man versteckte Scharniere benutzt, der Öffnungsradius des Fensters nur maximal 100 ° ist, sowie dass die Kippfunktion auch nur eine kleine Öffnung des Fensters zulässt. Da hat niemand uns darauf hingewiesen. Ebenso bei zweiflügeligen Fenster, dass es von großer Wichtigkeit ist, wie man das Fenster anlegt, damit es unseren Bedürfnissen entspricht. Jetzt sind wir schlauer, nachdem die Fenster eingebaut sind, wir sind jedoch mit der Öffnungsvariante, die wir gewählt haben nicht zufrieden. Heute im Nachhinein würden wir die beiden identischen Fenster austauschen.
Jeder ihrer Mitarbeiter ist sehr nett und sehr hilfsbereit. Sie arbeiten alle sehr ordentlich. Die Firma MHN, die den größten Teil der Fenster beim letzten Auftrag eingebaut hat, hat eine sehr gute Arbeit gemacht.

Es wäre vielleicht für die Firma OST sinnvoll einen Elektriker, sowie eine Firma die kleine Flickarbeiten machen könnte, zu engagieren, damit nach dem Einbau der Fenster und Rollläden bei Renovierungen auch alles fertiggestellt ist. Dann wäre alles aus einer Hand gemacht. Oft hat der Kunde Schwierigkeiten einen Elektriker rechtzeitig auf die Baustelle zu bekommen, sowie nachher den Maler nochmals für Kleinigkeiten ins Haus zu bekommen.
Diese Bewertung dient ja der Optimierung der Produkte und Dienstleistungen, sie ist auch in diesem Sinn geschrieben worden. Bei weiteren Fragen, stehen wir Ihnen jederzeit gerne zur Verfügung. Wir würden immer noch auf die Firma OST zurückgreifen und würden sie auch jedem weiterempfehlen.
