We start with a conversation to understand your idea and priorities. Then we make a free on-site visit and discuss the options. We prepare a clear itemized offer and an approximate schedule. You communicate with us throughout the whole process if you have questions.

How much does a renovation cost?

All finishing works are different and prices depend on several main factors, such as site size, required activities, and materials. We can give you a final renovation price only after a site visit, a conversation with you, and preparation of an offer.

What materials do you recommend?

We always recommend that finishing renovations are carried out with high-quality materials from the mid-range upward. They are tested, durable, and completely safe for you and your family. They also provide a long-lasting result and significantly better quality compared with cheap alternatives.

How does a renovation proceed?

It depends a lot on the type of renovation, but in most cases everything old and unnecessary is first cleaned, demolished, and removed. Then replacement, construction, and processing begin: plumbing, electrical work, walls, bathroom, kitchen, toilet, and other rooms. Finally come the installation works and furnishing.

What warranty do you provide?

The warranties we provide for each renovation vary depending on the activities we perform, the condition, and the type of renovation. As a guideline, we provide a warranty of 5 to 10 years.

How long does an interior renovation take?

The timeframe may depend on the size of the site and the required activities. This period also includes the technical drying times for some materials. Of course, additional delays can sometimes occur during the work process.

How does communication work?

Communication can be by phone, Viber, or email, and we periodically send photo material from the site after each stage. Meetings on site or in our office are also possible by prior arrangement.

How does payment work?

You can pay the full renovation amount or in installments by prior arrangement. We accept payments by bank transfer, through Revolut, or in cash.
