"Internet connection was weak, garbled communication. But, they remained very professional and we could crack a joke every now and then when things got annoying. Once up and running the diagnostic test was done in 5 min. Confirming my suspicions. Part number was sent within minutes."

"Hired to remodel 2 bathrooms. I should have hired Arayik to do the tile in the showers and floors only. The tile work was fine but electrical, plumbing and woodworking was unacceptable. Electrical outlets that were relocated had to be reset and wall repairs had to be redone to allow texture and paint to be done. Base boards installed by Arayik had very uneven gaps above tile floor and had to be replaced."
