A thorough approach to the matter! Concise answers to all questions! I 100% recommend this company! The gentlemen were very polite during both the measurements and the installation. 👍 Best regards, a satisfied customer.
I recommend this company 100%! Above all, their patience and reliability are top-notch. From the moment they selected the window to the installation itself, there were zero complaints, and there were countless emails leading up to the final purchase! ;) Mr. Dymytr and his team are the best. We'll definitely be using their services again 😉 ❤️❤️ For 3-meter window installation and more, BISOKNA is the only choice!
Excellent work!!! I arrived, dropped the guys off at home, and then went on with my business. They picked up the phone before the end, and I drove up and paid. They did the job quickly, efficiently, and with no complaints! Thank you so much, I highly recommend these guys!
Good morning. Nowhere else could I order a balcony wall in two weeks. Other companies have a 4- to 5-month wait and a much higher price. On May 3rd, I sent a request for a quote to Bisokna. On May 4th (Sunday), I already had a quote. On May 6th, Mr. Dmytro came to take measurements, and on May 17th, 2025, the wall was installed within an hour on Saturday. 💪 Great team, I highly recommend them. If you're planning to replace your windows or doors, it's easy to hire this company. You won't regret it! :-) Marzena Górska
