Plaster. Insulation.Drywall.One contractor.
A second-generation family trade business based in Rüsselsheim am Main. We plaster, insulate, fit out and refurbish — for developers, property managers and private owners across the Rhine-Main region.
A firm that genuinely carries out several trades itself
EG Bau GmbH is a second-generation, owner-managed family business based in Rüsselsheim am Main, led by Özkan Ertürk, who continues the firm his father built. Our focus is interior and exterior plastering, external wall insulation systems, drywall and painting — complemented by tiling, flooring and refurbishment.
Most of our work still comes through recommendation. In this trade that is the most honest measure there is, because nobody recommends a firm that misses dates or works carelessly.
What sets us apart from many competitors is the combination of trades. Contract plastering, drywall and flooring separately and you lose time at the handovers — and if something fails you have three firms pointing at each other. With us it sits in one hand.
What we carry out
Six trades, one point of contact. That shortens build times and closes the gaps that open up between separately contracted firms.
One point of contact
From the first site visit to sign-off you speak to the same person. No transfers, no call centre.
Dates that hold
Agreed dates are kept. If weather or preceding trades shift something, you hear it from us — not when nobody turns up on site.
Brand-name materials
For plastering, drywall and painting we use systems from established manufacturers and never mix third-party components within one build-up.
German, Turkish, English
Advice and site management in three languages. In the Rhine-Main region that is often the difference between a quote understood and one misunderstood.
Transparent quotations
Material, labour and scaffolding itemised separately. Variations are discussed before the work, not on the final invoice.
A clean site
Dust protection, daily cleaning and consideration for neighbours and tenants. In occupied buildings that is not an extra, it is a precondition.



The trade lives in the surface
What defines a building in the end is a few millimetres: the final coat of plaster, the edge at the reveal, the transition to the plinth. Those millimetres are our work.

Our catchment reaches roughly 50 kilometres around Rüsselsheim — from Mainz and Wiesbaden through Frankfurt to Darmstadt and Alzey.
