Most janitorial services do not do windows. While they might wipe off fingerprints and other blemishes that affect the inside of the glass, they are not trained or equipped to clean exterior windows at all floors of the building. To have these areas treated, you will need to find, screen and hire a reputable window cleaning company. Following are a few tips to help you in these efforts.
To start with, you want to make sure that your provider is capable of offering the types of treatments your building requires. For buildings with just one or two floors, it may be possible to use pressure washing equipment without the need for any special lifts of harnesses. Your provider can combine water with a streak-free solution and can then flush off all dirt and debris before letting these surfaces air dry.
In buildings with three or more floors, however, lift equipment and hands-on washing techniques are often necessary. Given the greater amount of danger that these entities face when offering their assistance, you definitely want to check their commercial coverage limits carefully. It is also a good idea to learn more about the types of mandatory safety training that employees are required to undergo.
Find out whether or not companies maintain competitive rates. If you hire the first business that you come across, you may wind up paying more than you need to. Bear in mind that this is not a set it and forget it solution. In order to keep your building looking its best, you will need to have these treatments performed at least three to four times each year.
Another important thing to determine is whether or not the company offers any guarantees. If your windows maintain a dirty, dingy look after being treated, a good company will be willing to come back and correct its mistakes free of charge. Spend some time reading through the feedback that other service users have left and ask to review copies of the standard job contracts that prospective providers supply.
