How to Bid Window Jobs

Window Cleaning Bidding Techniques

There are numerous ways of estimating window cleaning jobs, and I have seen plenty of different techniques from numerous window cleaners. Window cleaning is challenging work that not everyone can do, and so you should be paid well for your efforts.

Residential

Acquiring residential clients is a must in order to operate a successful window cleaning business. When a potential client calls you and requests an estimate, you can give them some general numbers over the phone to save you a trip, or you can be more thorough and go visit the property for an accurate bid. It is going to depend on how busy your schedule is, and how soon they need a price. If you have good closing skills over the phone, and can fit into their schedule, you can usually book the appointment over the phone.

Most homes have two panes per window, some have three or four panes per window and some are single pane windows. If you come across a home that has huge panes that are larger than four feet by four feet, then count those panes as two panes.

A good bidding formula to use is to charge $4 per pane for in and out cleaning, or $3 per pane for outside only cleaning. If you clean twenty panes an hour, which is one pane every three minutes, you will average $80 per hour. Let’s say you are brand new and can only clean fifteen panes an hour, you would still be making $60 per hour. If you counted 60 panes on a home, and the price is $240, it should take about three to four hours to complete. If you have counted up the panes on a home, and the price comes to $240 but it looks like it will take you eight hours to complete, then multiply 8 x $60 per hour, and charge $480. This is a good way to back up your original formula. For example, if you have a home with a majority of the windows that are 3 stories, it is going to take you much longer. In this case, size up the job, figure how many hours it will take, and multiply those hours by how much an hour you want to make.

We also need to price the cleaning of the screens. I recommend charging between one and two dollars per screen. In places like Phoenix and Las Vegas they use really large solar screens. These screens require a special cleaning treatment, and take longer to do than to clean a window. I think charging between seven and ten dollars per solar screen is a reasonable price.

Another type of window you will come across is a window with a bunch of small panes, usually having ten to twelve small panes in it. These are called divided lights, or French cut panes. A good amount to charge for these since they are a lot of work is $1.50 for in and out cleaning or $1 for outside only.

Commercial and Route Work

The formula to bidding commercial window cleaning work is very similar to bidding residential work. Again, we want to average between $50 and $75 per man hour. Walk around the building, count the panes, do the math, and make sure the numbers match up. Sometimes you will find buildings that are covered in glass where you can clean a pane every minute. You may not need to charge $4 per pane to be competitive, and may want to consider lowering your per pane price. Sometimes a property manager will need a bid for several buildings. You can provide a volume discount for the work, especially if you are bidding against other window cleaners.

‘ Route work’ is the easier and more frequent window cleaning work such as salons, restaurants, and store fronts. These accounts are usually cleaned each week or at least twice a month. This is the more competitive part of the window cleaning market, so keep this in mind when bidding on these accounts. Since most of the windows are ground level or done with pole work, they are done much more quickly than a normal commercial building. Go ahead and bid these lower at around $2 per pane. Remember to have a minimum trip charge for some of these accounts. Let’s say that you have to drive across town to do a store front with 8 panes of glass. I recommend a minimum trip charge of $25 for your time. Even though it will only take 10 minutes to clean that account, you may spend 40 minutes in traffic getting there and back.

If you happen to not be the winning bidder on commercial work, don’t hesitate to ask what the winning amount was. After I found out the amount of the winning bid, I would even ask which company won the bid. It’s a good way to get to know your competition, and adjust your bids accordingly.

Extra Tips for Bidding Advanced Window Jobs

New Construction

New construction window cleaning is going to be bid at a higher amount than regular window cleaning. Since it will take longer to clean each window and frame, we will need to raise the amount to at least $5 per pane for in and out cleaning, and $4 per pane for outside only cleaning. If there is a bunch of paint and mortar slopped onto the glass, charge at least $7 per pane.

Some construction projects will require you to rent a lift, or some call it a cherry picker. Check with your local equipment rental company for pricing. See how much the insurance, fuel charges, and taxes are for your bid. I always mark up the price of the rental in my bids by $100 to cover any other incidentals like extra fuel. I highly recommend taking a class on how to operate this machinery. The equipment rental company will offer these classes. If you are unsure what size of lift to rent, the rental company can send out one of their reps to measure it and recommend the correct lift. The two companies that I know do a terrific job, and have plenty of equipment available are United Rentals and Sunbelt Rentals.
