ABC System Grzegorz Masłowski

I highly recommend Mr. Grzegorz. He's a true professional, very knowledgeable, reliable, and above all, the installation of the new intercom was top-notch, on time. Mr. Grzegorz is a very polite and kind person, and he leaves the place tidy after the job is done, which is also very much appreciated. Thank you :)

I recommend Mr. Grzegorz's services. Complete professionalism.

Mr. Grzegorz is a true professional. I had a problem with my intercom and after buying a new receiver (the old one only worked one way), I decided to randomly call a specialist, because, as they say, "the good Lord did what he could, now it's time to call a specialist." Mr. Grzegorz turned out to be the one I chose. I made an appointment despite his busy schedule, "like a tarp on a Żuk," and it worked 100%. Everything works as it should, and the price was also very reasonable. I recommend Mr. Grzegorz to everyone! :)

A very professional and friendly approach to the customer. Mr. Grzegorz not only used my old alarm control panel components but also provided expert advice on how the system could be expanded to complete the installation. The installation itself was timely and quick.

I highly recommend Mr. Grzegorz and his assistant!!! I explained my problem with installing a wall lamp over the phone. Mr. Grzegorz immediately found time and came to see me the same day. He was accompanied by a very nice colleague. Both proved to be exceptionally competent. They completed the work quickly and efficiently, were very friendly, and were happy to provide me with any information I needed, including a short lesson in electrical engineering. Not to mention, they also fixed my iron! Not only were they not afraid of my barking dogs, but they also became instant friends with them, which was a joy to watch. I can wholeheartedly recommend these workers, and I will gladly use their services again the next time I need them. I was also very pleased with the price. Thank you again.
