How often should you clean your exterior windows?

As a general guideline, we suggest having your windows cleaned at least twice a year. However, there are various factors that need to be considered when deciding on a window cleaning schedule, such as the type of building, the type of business, the building's location, the landscaping, weather, and seasons; check out this great resource on window cleaning for facility managers.

What type of equipment is it used?

We have a variety of equipment and will use the one that is the most indicated for the type of job, some examples:

- Water-fed poles.

- Ropes for rappel descending.

- Lifts for high interiors.

Can you clean windows when it’s freezing cold?

Yes, one common method of ensuring water will not freeze is by adding methanol.

What type of training do cleaners have?

To ensure the safety of all crew members, ongoing training is a requirement. Every crew member must undergo training required by the Occupational Safety and Health Administration (OSHA). Additionally, it's essential to possess knowledge regarding different types of glasses.

What type of chemicals do you use?

Short answer: cleaning with soap and water, particularly dawn dish detergent, can be effective. However, the best method may vary depending on weather conditions and the state of the glass.

I just wanted to take the time to tell you what an amazing job these gentlemen did cleaning our carpets. I have worked with a variety of janitorial companies and carpet cleaners in my capacity as a facility manager with the State of Illinois, but these gentlemen were the best I have seen. They were prompt, professional, and knowledgeable in the arena of cleaning carpet. They exceeded my expectations and made the carpet look and smell amazing. I would be happy to work with them any day or refer them further business. If you need anything else from me, please

I would like all to understand that we are very pleased with the level of service and the way our facility looks since you folks have taken over. The communication that we have is awesome; we’ve never experienced this before. The emails about service and some of the things we’ve had concerns about, I consider minor tweaks in the overall scheme of things. Tom and his crew have been great and very responsive to our needs and desires… We definitely made the right decision, the difference here is like night and day
