Related FAQs

Can you remove hard water stains?

Yes we are able to remove hard water stains from your windows! Hard water staining happens due to the accumulation of mineral deposits, typically calcium and magnesium that are dissolved in unfiltered water slowly build up on glass. The typical culprits are irrigation systems that are broken and shooting hard water onto your windows but sometimes it can be due to poor window cleaning as well. You want to make sure to remove hard water when you see it as overtime it can etch your glass causing expensive repairs or replacements.

Based on the severity of the hard water different techniques and special chemicals may be required.  Regardless we are happy to help remove hard water stains on your property.

How do you minimize disruption for my tenants?

Minimizing disruption is our primary focus when on your property. We can work early mornings, weekends or even during the evening if needed. If we have to be onsite while your tenants are around our teams are uniformed, professional and quiet. They stay out of the way and most people don’t even realize we were there if it wasn’t for the beautiful view left behind.

What kind of insurance do you carry?

We carry all the standard insurance requirements for commercial properties.

  •       Workmans Compensation Insurance
  •       General Liability Insurance
  •       Commercial Automobile Insurance
  •       Bonded

We are able to get COI’s, waivers of subrogation, endorsements and additionally insured to meet your needs.

What if I don’t want my windows cleaned with water fed poles?

No problem! Although we do guarantee the results to be the same if not better than traditional squeegee on glass we understand some people might have a preference either way and we are happy to oblige.

Please make sure to note this during your request as we quote projects based on the most efficient way to clean your specific property.
