Customer Comments


Dear madams & sirs of DAUWIN®

Good morning,

Thank you very much for your interest and we always feel you close to us whenever we need something.

Nearly for half a year after the installation of frames, we are very satisfied with our choice. Both the quality of frames and the impeccable fitting and support services, strengthen our confidence in your company.

At present, we do not need directly any of your services. The malfunction of the lock of the entrance was fixed following the instructions of Mr. Krosi.

Although we have not yet proceeded to the refurbishment of the external space, I am sending you some photos to use for marketing purposes.

Please find some additional photos in the mail that will follow.

I am at your disposal.


Dimitris Athanasiou



Dear Sirs,

After our tour on the internet and in the reports of many companies we have decided to choose your company, for the quality, design, prices and the proposals presented us by the sales department in your Showroom in Athens. What has pleased us from our cooperation in the renovation of our traditional building of the 19th century, at Oreokastro, Pogoni, is that the replacement of frames has matched perfectly with the traditional architecture of the building.

Finally, we would like to congratulate your staff, both in the sales department and the fitting workshop, for their kind and professional integrity that have met our goals in our admittedly difficult requirements.

 Thank you

Jenny & Charalampos Loumaki


Happy Easter Holiday to DAUWIN®

I am sincerely happy for your email and the communication which you maintain with your clients as a company. This is yet another example of professionalism that characterizes you and justifies the confidence in the services you provide.

I do not think there is anything to criticize on the service level provided by your Sales Consultants (Dimitris, Konstantinos), whether this would have to do with technical, functional, or even aesthetic matters. Everything has worked up perfectly and you have shown due patience on my original hesitations about my final decision to convert the old energy-consuming aluminum frames to modern, energy-efficient, wooden ones. The important thing for me was that I had a clearer picture of how the final work would look like, even before the order was sent to the factory.

Particularly, I would like to congratulate the fitting technicians of the company. George and his crew not only they have excellent technical training and knowledge of the object, but George is also is a fine character and professional. This is very important, if you consider that you allow a “stranger” to essentially “invade” in your personal space. He has the gift of finding solutions and overcoming difficulties that arise during installation, which is a sign of ingenuity and technical training and deep understanding of the object.

On the whole, I would say that I am extremely happy with my decision to trust you.
If I had to choose again, I would not change anything in my decision two years ago. You deserve every positive comment that you hear or read, because you have toiled for it. I sincerely hope you continue to operate at a high standard service and with quality products at reasonable/affordable prices adapted to market requirements.

I wholeheartedly wish you every success in the future.

My friendly greetings to Apostolis and Dimitris.

Good morning Mr. Papavasiliou and Happy Easter Holiday!

The choice of your company was made initially after an in depth market research I did for doors and windows for an apartment in Byronas area and a cottage in Stemnitsa. The quality of your products, the prices and especially the service of your Sales Consultant made me trust you. The installation was made in two houses, by different teams, who they did a great job! But I want to say well done to the workshop of wooden frames, for their excellent work. The cooperation with the sales consultant was excellent and I thank him very much for it. The overall excellent cooperation with your company is your best advertising to our friends and social acquaintances! 

Thank you

Good evening, Mr. Dimitris,

Thank you for your mail and interest, both your own and of the company (DAUWIN®) which you worthy represent.

We are glad to hear from you, even electronically.

In reply to your message, I can tell you that we are very satisfied, both with the installation crew and by your service,

information and prompt response, whenever we have needed you.

However, regarding the frames you know that the shutters had a problem (cracks), because of “material failure” as you have explained to us.

It is true that with your immediate actions, these were replaced and that at present there is no further problem.

Finally, regarding the photographing of the project we are at your disposal.

It would be our pleasure to have nice pictures of our house on your website.

Good luck in your work.

We expect to hear from you

Mr. Papavasiliou good evening,

I am sorry about the delay of my answer.

I believe that the choice of your synthetic frames was extremely successful.

If you combine this with the great construction on your part and the very good installation of your workshop, the result is amazing.

Remember that the house was built in 1953 and its defects were too many, so the construction and installation have played a significant role.

I do not need any replacement part. The only minor issue is the balcony door in the dining room.

It needs a bit more power to close, but that is not a problem.

I have no objection for the website, but I don’t know either what I get, nor how.

Thank you for your interest,

Giannis Pasialis


Good morning, Mr. PAPAVASILIOU!

I have been very pleased with the product and the after sale service.

After the problems that had occurred during the initial installation and some material failures,

your response was immediate on anything that needed to be fixed.

Your professionalism and willingness to help solving the problems that arose,

as well as the efficiency and excellent work of the second team of technicians who came for the repairs and the new placement

have left us with the best impressions!!!

I would gladly send you the photos of the project for your website, as soon as we finish with the works on the external space.

We will be in contact for any further matter.

Dear Konstantinos and other partners of “DAUWIN® Papavasiliou”

I am very happy and pleased to answer to your letter to express our complete satisfaction - both mine personally and my wife’s- in our choice to trust DAUWIN®, and to highlight the fact that your company has indeed demonstrated high professionalism in all phases of our cooperation.

From the moment of placing the order for door & window frames until their final placement (and the after sale service), we came in contact with professionals who love the object of their work and they respect their own job as much as the customer.

Also, a very pleasant surprise for us was that you and your company, although you had given us the cheapest and economically most advantageous quotation (after an extensive market research we did), you have managed more than enough to lift any of our reservations about the quality in general of the products and of the provided services.

Therefore, well done to all of you, because in difficult financial times, you build quality relationships and trust by giving added value to the very reasonable and competitive prices.

Yours faithfully

George Siourtis

PS. Yes, you can gladly post pictures of our house on your site. Maybe it would be better to wait a few more days in order to have more spring color in the photographs. In any case, I will be waiting for your call in the next few days; we should not neglect this.

Γιατί να αλλάξω κουφώματα;

Τα νέα, σύγχρονα κουφώματα με τους ανάλογους υαλοπίνακες και τη σωστή τοποθέτηση επιτυγχάνουν καλύτερη θερμομόνωση. Πώς γίνεται αυτό; Μην επιτρέποντας τη μεταφορά της εξωτερικής θερμοκρασίας στο εσωτερικό του κτιρίου και ταυτόχρονα εγκλωβίζοντας τη θερμότητα στο εσωτερικό του, ώστε να μη διαφύγει. Με τον τρόπο αυτό επιτυγχάνεται η διατήρηση της ζέστης ή της ψύξης στο εσωτερικό του κτιρίου, τόσο το χειμώνα όσο και το καλοκαίρι. Η καλή θερμομόνωση εξοικονομεί ενέργεια και χρήματα. Αυτό συμβαίνει, επειδή δεν χρειάζεται υπερβολική χρήση οποιασδήποτε πηγής θέρμανσης ή ψύξης για την επίτευξη της επιθυμητής θερμοκρασίας. Απεναντίας γίνεται η ελάχιστη δυνατή χρήση τους.

Πόσο θα κερδίσω με την αλλαγή των κουφωμάτων; Πότε θα κάνω απόσβεση της επένδυσης;

Η αλλαγή των κουφωμάτων, εκτός από την εξοικονόμηση ενέργειας και την επιθυμητή θερμοκρασία επιτυγχάνει και την καλύτερη δυνατή ασφάλεια και προστασία. Εξυπακούεται ότι τα νέα σύγχρονα κουφώματα κλειδώνουν σε διάφορα σημεία, ενώ οι εξελιγμένοι υαλοπίνακες που εφαρμόζουν σε αυτά δεν σπάνε. Αντίθετα παραμένουν συμπαγείς, με αποτέλεσμα να χρειάζεται χρόνος και μεγάλος θόρυβος για να τους διαπεράσει κανείς.
