I cracked my 2nd window today on a first clean.

water was at 44 degrees and I was working on that pane for about 40 sseconds as it was proper filthy

it was double glazed upvc.  I got an estimate from a local glazier of £70 for cash supplied and fitted and left the money with the custies lad and called her at work to explain.

she was very understanding and chilled about it.

it was only a tiny semi (£15 first clean, £10 thereafter). hope this doesn't become too regular, my last one was about 2 months ago with slightly cooler water!

ah well, making more than enough dosh at the min, so I don't suppose it matters too much

cold water is so much better

[Dave Turley]

I take it you have't tried hot yet??

I won't be going back to cold, that £70 is nothing really compared to the extra money I make because im using hot.

no regrets here

ive never cracked a glass

I would like to try it, but this whole cracking panes business is really not good in my opinion. We really need to get some solid info on what is a definite safe temperature, where you can be certain nothing will crack. 35c perhaps?

so I don't suppose it matters too much   

It does to the person whos property it is. Its called respect.

Even if you've sorted out getting it repaired and paid for it out of your own pocket. If someone had an attitude of it doesnt matter after damaging my property they'd not be welcome here anymore. No wonder window-cleaners have a bad reputation.

Even at 20C there's a difference in cleaning power. 35C is plenty on most jobs,.. but I turn the dial up a bit on the first cleans and really dirty ones. I never use completely cold anymore,... even with the heater turned down to minimum its a world of difference from cold wfp!

[[GQC] Tim]

My Van gets really hot, so my tank water was well above 20c on hot days, I'm not sure if it made a difference on cleans, but they did come up well, but the hoses are so nice and supple, very nice to work with. I haven't had really cold days yet with wfp, but if it's chilly in the morning, the hose is much stiffer.

[Jeff Brimble]

Looks like 20 degree difference from the ambient air temp is the average use ie at 0C use 20C water at 20C use 40C water.
On freezing days 20C is only just about luke warm.

But the loss of heat through the hose accounts for about 6-10 degrees on freezing days ?

What Hot water system set up do you have!

[Mr H]

If he's cracked 2 in the summer I dread to think how many will crack in winter..!!

Good job he's earning more to pay for all those windows....... Although the local window company might offer him discount on all the repeat business...

How are you making extra money?

I understand it may be a bit easier on filthy first cleans, but don't try and tell us it makes any difference on a normal monthly or bi-monthly clean.
No way.

Indeed, I don't see it happening. Maybe he's talking about fascia's and Conservatories as well though. That would work very well I can imagine, only cracking a pane on a conservatory 'might' be a bit more then £70. 

[Dave Turley]

it's a diy hot water system.

in my opinion hot speeds the cleaning part of the job up by 20%

and it doesn't matter too much this time as the woman isn't fussed and it was a small window (not costly)

I do intend to lower my temperature a bit to try to reduce the chance of cracking

[Jeff Brimble]

I think its good of Dave to admit to cracking the glass and letting us know and maybe we shouldnt give him so much stick as he is just passing on info. What we do about it is  up to us as individuals. There are many hot sytems out there now and the general opinion seeems to be they make the job easier.

Dave was it std modern single thickness float glass or small georgian style fine glass ? I also wonder whether the frame was already under some stress ?

[LWC]

not costly! £70 out of my back pocket would be costly to me lol

my thoughts aswell

esp by all accounts with the gas bills rising peopl will be sat in cold houses with 3 jumpers and 2 jackets on 

[karygate]

tell us if were wrong. but the only difference between hot and cold water is patience and a bit of elbow grease

The faster you can work = the more money you make though.

[Dave Turley]

thanks for the support jeff, it was a standard modern double glazed unit

and imo patience and elbow grease cost time and therefore money
