FAQs – Answers on Houzy

How accurate is the result of the online Renovation Calculator?

FAQ arrow

The result of the Renovation Calculator is based on an analysis model by QualiCasa AG - the Swiss expert in building analyses for over 15 years. By definition, a model does not reflect reality exactly. It is intended to provide a point of reference for taking a closer look where necessary. In order to make an exact analysis of the building components and the corresponding renovation needs, you still need a specialist on site. You can also find a broad regional network of experts on Houzy.

What information does Houzy need for the Renovation Calculator?

FAQ arrow

Important for the evaluation of the Renovation Calculator are the basic details such as address, year of construction and house type. Information on the materials of the various components (e.g. the roof or the façade) as well as renovations already carried out make the renovation calculator much more accurate. In the "Pro version", additional information on the standard of construction and condition can be entered. Rooms and building components can also be entered several times and more specifically, which leads to an even more precise result. In short: the more information you can provide, the better.

Why is the Renovation Calculator free of charge?

FAQ arrow

Houzy is a young company and finances itself by brokering third-party services as well as through advertising partnerships with national and regional partners (however, you as a user always decide yourself when you want to share what and with whom and thus always retain data sovereignty). The use of our online Renovation Calculator and our platform is therefore permanently free of charge for you. If required, our experts will be happy to advise you personally in a second step. Suitable, regional craftsmen can also be contacted through us without obligation. If an order is placed, payment is handled directly with the craftsman.
