Frequently Asked Questions

Naturally! If you wish, you can arrange transport by yourself.

Yes, you can! Additionally, we offer support after the guarantee period is over. It means that if something happens with your joinery afterwards, we can get you all the necessary spare parts, ready-made products and tools to help you solve the issue (the service is chargeable at the end of the guarantee period).  Please note that if you choose your own fitter, you are responsible for providing them with correct measurements of the openings as well as products dimensions. We cannot be held responsible for any irregularities in this regard.

You can contact our customers at FACEBOOK (check the reviews) and see the pictures they sent us. Unfortunately, we cannot share any of our customers details (like their address, etc.) with you. Our privacy policy doesn't allow us to do any of that . But still, you can contact those customers who left their comments on Facebook on your own. Additionally, on our website, there is a section where you can see some of our realizations in Ireland. For customers in Ireland: If you wish to see our windows, our fitter (based in Ireland) has all models: samples and colour samples as well. When you are ready with the order, he will bring the samples for the final measurements meeting.

Your house plans are not necessary for us to prepare the quote for you. It would be much more efficient for us to have the list of your joinery together with the following details:

  • Width x height [mm]
  • Colour
  • Glazing: double/triple
