About Our Company

"We've had them for more than 10 years. We're a pharmaceutical research firm, so they are asked to do a lot for us from a maintenance standpoint. We also have different environments: offices, warehouses and research areas. And they do good janitorial and maintenance in the whole building. They bend over backwards to accommodate us and our specific needs. They also do our carpet cleaning, strip and wax our floors, and do our windows. We've been very happy with their services. We get solicited all the time by other janitorial companies, but Altech Building Services does such a good job that we never even consider anyone else."

"Altech Building Services has been doing our work for a long time, and they are very reliable. I highly recommend them. Some cleaning companies get complacent and certain things start getting missed, or they're not as thorough. But Altech is definitely consistent with their work. They do a good job and stay on top of things. We're a winery, so we need extra services sometimes and may only have a few days' notice. They jump right on it and have someone down there that night to take care of what needs to be done. We greatly recommend their crew."
