We ordered the installation of a balcony last year, first the measurer came, took the dimensions and also helped with the jammed windows. An advance payment was made and two weeks later the order was ready, two craftsmen arrived at the agreed time and within 10 hours dismantled the old balcony and installed a new one. We are very satisfied with the work, we can safely recommend it. Prices for August last year were lower than average in Lugansk.
The disadvantages are that the measurement of the window sill was less than it should be. Secondly, when installing the low tide, they simply cut it off smoothly, without recesses for the length of the hollow.
I ordered windows, we arrived at the time we took measurements, then we arrived on the agreed date, we were satisfied with the quality, everything has been in order for several years.
