Common questions

Answers

What advantages do mineral facades plasters offer?
Mineral facade plasters are robust, breathable, and support a balanced moisture behavior of the facade. They are well suited for durable and visually appealing surfaces. In addition, they contribute to a high-quality and natural facade appearance.
Does Glanzmann & Stocker AG also carry out acoustic measures in interior spaces and how do we manage it all?
Yes, the company also implements acoustic measures for interior spaces to reduce reverberation and improve room acoustics. Especially in large or heavily frequented rooms this provides more comfort and better speech intelligibility. The solutions are planned to suit the room's use.
How quickly do customers receive a quote?
Within 24 hours
Does the company also offer drywall for remodels and new builds?
Yes, we carry out drywall work for remodels and new builds. This includes metal stud walls, gypsum board partitions, full gypsum walls, as well as ceiling coverings and suspended ceilings. If desired, we also take fire protection requirements into account.

How to Turn Spritzputz from Spritzputz into Glattputz?

Many expect that the actual plastering determines the effort. In the practice of Glanzmann & Stocker AG, something else is often decisive: how many square meters must be worked on, how extensive the covering is, and whether ceilings and wall surfaces are well accessible. These exact points are missing on many websites, but are crucial for homeowners when planning time, dust and workflow realistically.

In practice, however, the invisible build underneath often decides whether connections align neatly, doors still fit and ceilings look calm later. This is exactly where the work of Glanzmann & Stocker AG starts, with consulting and execution in plastering, drywall and acoustic measures.
