Renovation, clearly planned.
Built on window expertise.
We believe a renovation should begin with clarity: a traceable indicative price, an understandable scope of work and one point of contact who coordinates all trades.
What Klarwerk does
Klarwerk is the digital starting point for renovation projects in Germany, Austria and Switzerland. Homeowners describe their plans, upload photos and receive a non-binding indicative price with a structured scope of work – within minutes, without sign-up.
Our team then reviews every project personally, asks follow-up questions and prepares a binding offer. On request, Klarwerk coordinates the entire execution: materials, qualified specialists, schedules and documentation.
Our origin is made-to-measure uPVC windows, balcony doors and lift & slide doors. That expertise remains the core – and the benchmark for how carefully we take on every additional trade.
