My name is Armin Kalac, and K-Konzepte grew out of a simple observation: anyone who owns a building is constantly juggling tradespeople. One does the roof, the next the heating, a third cleans the windows – and nobody feels responsible for the whole.
That is exactly what I do differently. Whether it's a photovoltaic system, heat pump, heating, plumbing, electrics, building cleaning or ongoing caretaker services: with K-Konzepte you have one number, one contact person and someone who really knows your property.
What you can expect from me is already on my business card – and I mean it: competent work across all trades, reliable appointments without excuses, and sustainable solutions that make your building fit for the future and cut running costs.
Just give me a call. We'll look at your project together – no obligation, as equals.
Call us directly or drop us a quick line about what you need – we'll get back to you within 24 hours.
