Window cleaning pricing

OK I know that I should be at the window cleaner forum for this but I do not have an account set up for that yet. I know that some of us definitely do windows here. When you are bidding a window job it’s one thing to do a general cleaning with water fed pole but when you run across water spots how do you charge for those? Is it time and material or X amount per window that has water spots? Cleaning water spots takes 20 times longer than general cleaning…

There is always a separate charge for hard water, and for me it is usually starts at 5 times what a normal cleaning costs. That includes sealant.
I try not to do a lot of it. Most of the time customers are happy with regular cleaning.

It really varies quite a bit when you’re dealing with hard water. Some times just a little steal wool will take care of it. Or steel wool and vinegar. If the steel wool and vinegar do the job then somewhere aroumd double is reasonable. I always start with those two first when I’m diagnosing how bad the staining is. If those don’t touch it then you’re talking a whole different kind of job than basic window cleaning and youre going to require chems and a grinder and lots of time. If you’re not sure how long its going to take. Do 1 window for free as a demonstration then you’ll know what to charge for your time. Plus it will help sell the job when you meet the homeowner and show them what you can do.

We start out at 20.00 per window pane and go up depending on how bad the hard water is and what chemicals and equipment needed. It’s definitely costly to the homeowner but we do them every year. We average 150.00 an hour on glass restoration. So price accordingly.


Don’t bother with it, Stick to cleaning only… That’s more on the restoration side of window cleaning, and trust me… There’s not 1 chemical that removes it all, Sometime some work in one scenario and that same chem might not do squat on the next job…

If you see spots prior to cleaning, just notify the client and clean them regularly… and keep going


Agree with Cheesbro, I have one ‘screen deposit’ remover, BioClean. If it doesn’t get the spots off, I inform the customer and move on.

Customers here are not interested in paying more than my usual WC prices.


I am a window cleaner by trade and I agree with @Chesebro and @dcbrock, keep in mind that window cleaning and glass restoration are two different things entirely. My policy is that I do not do glass restoration, period. I will clean the glass, but if there is damage (hard water, etching, etc.) it’s not my job. I inform the customer, and they are understanding.
If you want to get into glass restoration, that’s fine, just understand that it is a deep tunnel and you should know what you are getting into.


Don’t even offer hard water removal unless you are going into restoration all the way, scratch removal etc. It’s too complicated to do as an add-on to pressure washing.

One restore will get it clean, awesome stuff. Most wont do restoration around here so we keep gallos of that stuff on hand. Try One Restore, I think you’ll like it.

One restore is nasty stuff, I would not recommend it to someone starting out, it has hazed glass to the new guys using it. I have used it, and it has failed me in some jobs, hence why I say there’s no 1 chemical cleans it all when it comes to hard water removal

Like any chemical you need to do what instructions say. Most times when things go bad that will be the case. It’s like spraying 12.5 SH on a house, not good. But yes with window restoration you have to be careful, I wouldn’t recommend it to new ones getting into the business unless they had some good training. I didn’t start doing it till 10 years in, been at it over 25 years. But with YouTube everyone thinks their a professional, lol. Another one we keep on us is A-1 stain remover, we use for the light stuff, works good for like light sprinkler water damage, minor stuff. Use to use CC550 but no longer do. Much success!

I’ve done windows for 11 years and i cringe at the thought of trying to up sell restoration. Maybe 1 in 100 customers have asked about it and when I tell them the potential price they just laugh and say “it’s not that bad, we can live with it.”

Yeah, some do. We do real high end homes on farms and they don’t flinch to pay it, the cost to replace a custom Pella window is so much more. So…but yes, your standard spec window most won’t pay the extra 50-60.00 for the two panes. We did a whole house of them two years ago, took two days but paid well.

So what’s the deal with window restoration why is it so hard and what do you guys do. I’m too embarrassed to join a window cleaning forum.

My sister-in-law and her family live 45 minutes or so east of Lexington. We live in IL so go through there on the way down. Those horse farms are insane. The fences alone are worth more than most houses in well off neighborhoods. I’m only talking about the ones we can see from the interstate. I bet there are some real nice secluded farms on hundreds of acres.

Yeah, and the thing is…all that open space/fences and you might see a couple horses. The road from 64 to Versailles is a prime example.

Cool, yeah a lot of farms. We’ve worked on many, some with derby horses, absolutely beautiful farms. They even clean the windows in the barns, which are amazing, heat and air in them. Most of the farms have many homes on them, plenty of work, some don’t even ask about price. They just say get it done. We did some work at The Castle in Versailles, Kentucky, look it up, cool place. Pretty big castle. Take care.

No big deal really, just another add-on service. You’re just removing most of the time hard water that has built up for many years. Making the window clear again, without the service the window can look a little foggy or badly spotted. It ranges from light to severe damage.

Stage One:
This stage usually happens when hard water has been sprayed onto a window once or twice with ground water from a sprinkler or garden hose. After the water has evaporated, visible spots are left behind.

Stage Two:
At this stage the mineral deposit has started to build up to the point where it has a somewhat transparent, but white pasty look. At this point, it may be difficult (but not impossible) to remove with normal scrubbing

Stage Three:
This is where the hard water deposits have build up to the point where they have etched into the pores of the glass. The scale build up has not only damaged the glass, but has damaged the frame as well. You will see this a lot of times on shower glass and doors along with lower outside windows that have been hit over and over by sprinkler systems. You will know the damage has been done when the window scraper or cleaners will not remove the scale build up, no matter how hard you try.

We usually do stage 1 & 2 restoration around here. It takes certain chemicals and equipment to complete the job. Can be tedious at times but not real bad. We start out at 150.00 per man hour, but average more most of the time. If there are scratches, that is another whole system, to remove the scratches with a paste and power tools. That pays 250.00 hour, most of the time when doing commercial customers or some real high end homes. Sometimes brick layers clean the glass and cause damage, so…anyways hope that helps.
