What our clients say
Avcılar
We had external insulation done on three blocks of our complex. The person who came for the survey explained everything down to how many anchors would go on each side, and the quote came itemised accordingly. Rain delayed the job by two days, but they let us know in advance. This winter we are running the boiler far less.

Kadıköy
We live on the top floor and water came in at the corner of the living room every time it rained. Another company said the whole roof had to be replaced. Nesim Grup went up and found the problem was the flashing around the chimney and a few broken tiles. They fixed it in half a day; two winters later, not a drop.

Pieces of concrete had started falling from under the balconies and the neighbours were worried. They came to our meeting with a photo report and a quote, which made the decision easy. They cleaned the rebar, rebuilt the render and then painted the whole facade. They left the entrance clean every evening throughout the work.

Beylikdüzü
We had the exterior of the house repainted. I could not decide on the colour, so they painted two samples on a corner of the wall and we chose from those. After the scaffolding came down a few spots around the windows needed touching up; when I called, they came the next day. Overall we are happy.

Ataşehir
In the flat we had just bought we had a suspended ceiling, concealed lighting and wall panelling in the living room done. Since the plasterers and painters were the same team, nobody waited on anyone. They finished a day earlier than promised and cleaned up before we moved the furniture in.

Our building was insulated during construction but cracks had appeared at the corners. Instead of stripping it all, they suggested a mesh plaster repair, which almost halved the cost. The new render does not match the old facade exactly; they told us this from the start, and we plan to even it out with paint next year.
