Very Disappointing & Unprofessional Experience
A big disappointment with Wouter, Olaf, and the Finstral team.
Our PVC triple-glazing windows were supposed to be completed between 7–14 October. We clearly requested that the work be finished before winter, yet as of 9 January, the installation is still not completed.
The delays have been endless and poorly managed:
Trucks arriving incorrectly
Raw materials taking weeks to arrive
Materials delivered to the wrong address, after which they were reportedly lost or stolen
Workers arriving unprepared and without the right materials
Communication has been extremely poor. We tried repeatedly to call Wouter to discuss the issues, but calls were not answered. We escalated the matter to Finstral via email, but the response from head office was weak and ineffective, as if there was little interest once 95% of the payment had already been received.
We have lived through extreme winter cold with indoor temperatures below 15°C, despite installing triple-glazed windows. There was no sense of urgency, responsibility, or basic humanity shown by the team to prioritise completion.
I understand this was a large project (all windows and doors were replaced), and such work takes time. However, the issue is not time — it is false assurances. We were repeatedly told the work would be completed in one day, yet it never happened. On top of that, the workers caused additional damage to our property, which then required further follow-ups.
Based on this experience, I would not recommend Finstral. If you do choose to work with them, do not release final payment until every single item is completed and inspected. Releasing 95% of the payment early was our mistake — we did so trusting that Dutch professionalism and responsibility would prevail. Unfortunately, that trust was misplaced.
Very disappointing experience overall.
