1) Cell phone.
Stays in the car on the job.
No non-essential web surfing, texting between jobs.
Ok, thats out of the way, now on the job....
Not scrub, scrub, scrub down the line... squeegee, squeegee, squeegee back.... detail, detail detail back a third time.
Finish a window or two, move to the next 2, next 2, next 2.....
3) Trips back to the vehicle/forgotten items.
Have everything you need from the start.
Mental checklist before every job:
4) Insides first/Logical workflow/Claim your space.
Break the inside of big jobs into zones. Zone is defined as section of windows that will be inaccessible if a customer sits there. Could be 1 could be 6 or more windows.
Clean potentially busiest zones first.
Clean drive thrus when not busy.
Claim space by dropping a clean huck towel on the row of tables blocking windows immediately ahead to be cleaned. Remove hucks as you go.
Know it. Be able to reach, grab tools and replace with minimal looking down. Autopilot. Muscle memory. Like a concert pianist. Or skilled typist.
Same movements over and over again. No variations. Perfect your motions. Start slowly. Speed will come naturally.
6) Spot checking as you go.
As you move along, look back at windows already cleaned. A different angle, distance and lighting will reveal what you missed but doing it while cleaning the current window or as you move from one to the next.
Keep it short and pleasant.
8) Direct Sunlight.
Avoid it if possible. Except in winter, where it can be your friend.
If you are in it, clean top half, detail if necessary. Clean bottom half. Onto next...
9) Straight pulls.
They are the fastest.
Pole working as much as possible also is faster.
Buy a 14 or 18 inch Combi or Precision glide. Screw the pad right into the extruded aluminum with self trapping screws.
When you have the Wag mastered, move on to Excelerator.
These two tools will reduce your time considerably.
