My largest account currently is a house I do biannually, I believe itās around 8-9k sq ft. Tons of vaulted ceilings and interior ladder work. Mostly divided panes. Takes me 4-4.5 days to complete working solo.
A little under $3k for each cleaning. On the last two cleanings, the customer tacked on a 10% tip 
Iāve had a number of houses in the $1500-2200 range. I rarely bother looking up the square footage on houses unless Iām doing a housewash (low pressure power washing). In my market, square footage can be rather irrelevant to how many windows they have or how long they may take to clean.

My biggest resi was $2075, but considering it was many years ago when I didnāt charge much, it would probably be around $3000 if they were to call me today. The largest yearly we have now is $1650 for all windows and gutters.
I had one up till around 3 years ago that current pricing would amount over $2000
58 storm windows with interior french panes, plus a sunroom that has about a dozen french doors. Itās the worst. We do it every year, 4 man crew and a can of WD4 on all the interior windows so we can get them up and down.
A house that had a basement that had a swimming pool , Full gym , 2 lane bowling alley, full bar , Movie room .
The type you donāt count windows on, because then you have to add 2 hundred to the price.

Did you clean the inside of those skylights above the pool?
Noā¦that would have been a major challenge.
Iāve long imagined what it would be like to clean that house.
Really? Are you in SD?
Yes, we major in La Jolla, but have a handful of clients in RSF.
Great. Hope you guys are having a great year. SD is a top spot for us to work in.
Nice one Paul. Iām jealous.
Always wondered what it would be like working in SD. Perfect weather year round. 
$2803 11,000 sq ft. more than 700 large french panes (windows divided up into 12ish by 18ish inch panes) we had to remove silicone from recent glass replacement)
It was a kick. 3 times we did the place and then a death in the family and that was the end of it. Money wasnāt an object. In/out/mirrors/skylights/gutter clean/roof clean/whatever.
Man! Iāve had a couple of those over the years. Not as nice as the one you did, but same situation.
Death, and moving did it for mine.

Hello - I just started out window cleaning this past summer by word of mouth to learn skills. I love it. Besides our own home, I had only done a couple homes and had really under estimated my time - but know I have to learn and earn my way up. I had just bought my first BOAB. I got a referral to do a glass walled oceanfront home. Window cleaners dream!? This is a $7M home with the main level 90% glass walls - walk in on ground level, then slope down and basement walks out on lower. I counted 50 panes of 5āx10ā not to mention interior glass doors, and glass patios, basement windows. $10K per large pane Iām told was the cost for the glass. Seamless glass - only the corners have āframesā. And itās got a stainless steel sill that is about 10" wide that had to be wiped as they keep it spotless - all the way around the home. Nearly all of this glass is the 2nd level of the home requiring a ladder - ON the glass - itās rated for weight since itās the walls. I was told to go ahead and put the ladder up onto the glass (padded ends of course) 
I used a 24ā extension mostly - and used it nearly full height. 2 ends of the home joined by a portion of the home that is āsuspendedā or like a walkover in a downtown city. The living room is in that portion - completely see through! Oh, and on a serious slope to try and stand a ladder up on the sides. Thankfully not much foliage - as itās pretty new. So. Iām new, no waterfed pole for me at this point - and this house would be the well served by a waterfed pole. I just donāt have the budget yet. I had to work around the sun - moving to be out of it. Once that sun hit those panes - wowzers. It took 42 hours over 4 days, I had help for about 8 hours of that, but she was a beginner too. I redid some of her initial work - gave her the patio glass ground level and she helped me indoors by doing the mopping ahead of me. I charged $1500. If you do the math it was around $35/hour. And I worked my BUTT off for that. I was so sore from moving the ladder and reaching I could barely move at night. Possibly some of this I could pole in future visits, but not sure if the pole will kill me faster than moving the ladder or not 
These are amazing owners. I was told I would be asked back - they were pleased with my work - an incredible relief as I was unbelievably stressed to do a stellar job. I canāt wait to one day have a waterfed pole for this jobās exterior. Itās a stunning place to work, an architectural beauty, and wellā¦ oceanfront.
I did take photos, but am hesitant to post since itās pretty recognizable to anyone from this area of the west coast. so that is my story of the biggest house - maybe not biggest here, but certainly the most remarkable windows.
Thanks for ālisteningā
P.S. I am a woman. I am 50. I was a farm girl / horse trainer before moving here 3 years ago and starting a new life. I believe I know how to work. This job is to be my seasonal endeavour since our winters arenāt really conducive to window cleaning, itās a seasonal location, and I head to warmer places with the flock. Iām very lucky, and excited to be taking on this new adventure. I plan to focus on residential, and to do it well. Enjoy reading these blogs and learning from those of you so willing to share your stories and experiences. I am just planning my promotions for the spring season, and hope to find enough work to keep myself and a friend busy for spring/summer as much as we can handle. The information here, and on youtube has been invaluable.

Welcome!
Nothing wrong with āpaying your duesā. For several years I was very modestly equipped when doing houses. Sheer willpower and some ingenuity got me through it. Hope all goes well and that you can invest in a wfp soon 
Not a cure-all, but definitely a game-changer.
