The ProvenExpert Quality Seal is awarded to service providers who have received at least 10 customer reviews with a recommendation rate of 90% or higher.
We quickly realized that Mr. Nielsen was keen to give us good advice.
He found that the windows on the lower floor still had the factory settings. Here it would be enough to readjust them and provide them with new seals.
Mr. Nielsen advised us to replace the windows on the upper floor and showed us the defects. In fact, these windows were much older than the lower ones.
It became clear that selling at any price was not his first goal.
The windows have been processed or installed and we now notice, already after a week, that the indoor climate is more pleasant and it is warmer in the house.
The cost estimate was prepared very promptly and the work to be performed was presented to me transparently. There is always someone available for questions. I would recommend Nielsen GmbH at any time.
We built a new house 15 years ago and Glas Nielsen did all the windows, doors, front doors and interior glass inserts. We are very satisfied with the perfect work of Glas Nielsen and also the aftercare. Our absolute and unreserved recommendation!
