I used OS Holding for kitchen demolition, electrical work and to replace wooden flooring. Vadim was quick to come out and provide a quote, that was competitively priced, and they were able to start the work when we needed. There were some unexpected issues encountered along the way but Vadim was always available by phone and ensured the issues were addressed, and the guys doing the work were friendly and efficient.

The OS-Holding company is run by Mr Vadim. All staff is very professional and very well trained. They insulated my large roof (230 m2) using only top class material from special panels with the best insulation capacity available (low lambda). They searched and provided material on a competitive low price. They spent several time ensuring that no gaps were left between each panel/joystick. Furthermore, they used special spray to seal any gap left.They were all working very efficiently and active on a much higher standard than this of the average Irish builder/carpenter.This people from East Europe are really committed and hard workers. They left all clean including hoovering after work.Price /Quality was exceptional good compared to Irish standard!!!They respected the quotation given even if more time than calculated was required!! Finally we have in this country a decent company that is capable and that can do things as should be done!!

Highly recommended! I called Vadim to quote for a full bathroom renovation and he was able to come out assess and quote within a matter of days. Once I accepted the quote Vadim was able to start within a very reasonable time frame and able to offer advice on products. I couldn't be happier with my new bathroom! I found the work done was to a very high standard with Vadim available at all times for any queries I had. Very reasonable price, I will definitely be calling upon Vadim for my next project!
