“To start with, I was very happy with their service. The contractor I was in contact with sir Gladkov was quite flexible and answered all of my questions. However, when I asked him to come measure the ceilinh height he made a mistake and took the wrong measures. I kindly and diplomatically asked him to take responsibility for his mistake which he firstly admitted and apologised and wanted to pay for the extra cost I had to spend to fix the issue since the material had already been bought. The next day he decided it was not his fault anymore and refused to take responsibility for his mistake he althought admitted the day before. Hence I give them only 2 stars because mistakes happen but if someone doesn‘z wat to take responsibilty for it it‘s done to me.”

Response from the owner

Thank you very much for your review. We are pleased that you were initially satisfied with our service. At the same time, we would like to clarify that we did not confirm any error, but merely mentioned that we could not explain the dimensional deviation. Our measuring device was subsequently checked and worked perfectly. The measurement was carried out together on site, the values were noted down by you and used independently for ordering the material. Furthermore, we did not have a written order. We ask for your understanding that we can therefore accept no liability for materials ordered by yourself. Sincerely HSL-Technik

Vielen Dank für Ihre Bewertung. Es freut uns, dass Sie mit unserem Service zunächst zufrieden waren. Gleichzeitig möchten wir klarstellen, dass wir keinen Fehler bestätigt haben, sondern lediglich erwähnt haben, dass wir uns die Maßabweichung nicht erklären konnten. Unser Messgerät wurde im Anschluss überprüft und funktionierte einwandfrei. Die Messung erfolgte gemeinsam vor Ort, die Werte wurden von Ihnen notiert und eigenständig für die Materialbestellung verwendet. Zudem lag uns kein schriftlicher Auftrag vor. Wir bitten um Verständnis, dass wir daher keine Haftung für selbst bestellte Materialien übernehmen können. Mit freundlichen Grüßen HSL-Technik

“I am very satisfied with HSL's service! The advice for the new heating system was competent and understandable, and the implementation was fast, clean, and professional. The air conditioning installation was also perfectly adapted to our spatial conditions. Very friendly team, punctual, reliable – just as you'd wish. Clear recommendation!”
