10 Best Home Renovation Companies in Vienna

Renovating a flat or house in Vienna usually means choosing between a licensed master builder's firm, known as a Baumeister, a general contractor that coordinates partner trades, and smaller renovation firms focused on flats. Altbau flats bring old pipes, wiring, floorboards and box windows, and work on shared parts of a building involves the property manager.

This guide lists firms whose own websites describe home renovation work. For each one we note which trades it handles itself, how quotes and site visits work, whether it offers fixed prices and which areas it covers.

How to choose Home Renovation Companies in Vienna

  1. Ask who actually does the workSome firms employ their own crews, others coordinate partner companies. Ask which trades are in-house and who is liable for the partners' work.
  2. Get a written quote after a site visitOld buildings hide surprises behind walls and floors. An itemised quote based on an inspection, with clear rules for extra work, makes offers comparable.
  3. Check the licence for structural workRemoving or opening load-bearing walls needs a structural calculation and usually a notification to the building authority. Make sure a licensed master builder signs off this part.
  4. Involve the building earlyIn rented flats the landlord must agree to major changes, and in owner-occupied buildings the other owners or the property manager may need to approve work on shared parts.

Frequently asked questions

How much does a flat renovation cost in Vienna?

It varies. The price depends on the size and condition of the flat, the trades involved, the materials chosen and whether the building is listed. Old buildings often reveal extra work once floors and walls are opened, so compare itemised quotes made after a site visit.

Do I need permission to renovate?

Painting, new floors and similar work usually need no permit. Changes to load-bearing walls generally require a structural calculation and a notification to the city's building authority. Tenants need the landlord's consent for major changes, and owners need approval for work affecting shared parts of the building.

How long does a renovation take?

A single room can take a few weeks, while a complete flat renovation often takes several weeks to a few months. Material deliveries, drying times and approvals from the building add to the schedule, so ask for a written timeline with the quote.
