Frequently asked questions
What services does Constant Sanitär & Elektro offer?
We offer five core areas: plumbing installation and bathroom refurbishment, heating and heat pumps, electrical installation and smart home, air conditioning and photovoltaics. As a full-service provider we handle everything from one source – from consultation and planning to installation and maintenance. Our service area covers Upper Austria and Salzburg.
Is the initial consultation free?
Yes, we offer a non-binding initial consultation – by phone, email or on site. For larger projects (bathroom refurbishment, heat pump, PV system) we visit you for a site survey and provide a detailed quote.
In which area is Constant Sanitär & Elektro active?
Our main location is in Wels (Durisolstraße 1). We operate throughout Upper Austria and Salzburg. This includes Thalheim, Marchtrenk, Gunskirchen, Steinhaus, Krenglbach, Lambach, Bad Schallerbach and other municipalities in the region.
Can I combine several services?
Absolutely – that is one of our strengths. If you want to combine e.g. a bathroom refurbishment with new underfloor heating and LED lighting, we coordinate all trades. That saves time and cost, and you have a single point of contact for everything.
