Quotation / Price indication request:

You can request a quotation or price indication for a dormer window using the request form below. The more information you provide to us, the easier and faster we can submit a suitable provisional quote / price indication. For example, think of:

  • Whether the dormer window occupies one or more rooms (partition).
  • Additional installation of shutters or the possibility thereof.
  • The roof of the dormer needs extra reinforcement due to placement of the air conditioning unit or something similar.
  • The placement of the dormer is hampered by poor accessibility (deep garden, narrow access road, small bridge and the like).

In the "comments" box you can add this additional information simply and in your own words.

You can also attach a photo or drawing.

Contact us with any questions or if you want more information.
