The company Grunwald GmbH convinces with its friendly, professional customer service and its on-time, careful and convincing execution. Here also the boss comes out personally, if his must! No matter whether questions arose during the preparation of the offer or in the course of the construction work, the company Grunwald was always available and took care of all concerns promptly. Special thanks to Mr. Chopra for the great support of our project!
A very nice team in all departments. Expert advice was given. Very friendly and very nice staff. Even with some change requests on our part, friendly and quickly adjusted the offer. Timely appointment and the installation of the floor heating was really perfect. Clean, fast and the employee very nice and funny. We can unreservedly recommend the company Grunwald and their system and recommend it to anyone who wants to install underfloor heating without having to replace the entire screed. Many thanks to the entire team!
We are independent architects with an office in Düsseldorf. We wanted to retrofit a floor heating system in a single-family house built in the 1970's. Grunwald was recommended to us. The entire planning and preparation time was optimally cooperated. The result is very good. We can recommend the company Grunwald with the best conscience.
The company Grunwald submits a competitive offer very promptly. The work is done professionally and in high quality. The extension of the floors with underfloor heating via the company Grunwald can in only recommend.
Company Grunwald has retrofitted underfloor heating in my apartment in the spring of 2020. The work was carried out to my complete satisfaction. What I particularly appreciated was the completion of the work. The ducts were sealed and the entire area was filled with a levelling compound.The fitter work including ceiling breakthrough into the basement and connection to the existing heating system were also carried out very accurately and neatly.
I can recommend Grunwald to others.
For many years, Grunwald has been our first point of contact when it comes to underfloor heating. Together we have already realized and successfully executed many projects.
We are looking forward to further projects with this competent team.
This company can only be recommended. Everything simply works here. Even during the consultation, you notice that competent people are at work here. Here, customer service is still written large. All deadlines were met and the work was done correctly, professionally and cleanly. Very nice and friendly team. I am more than satisfied.
