Water run marks on sills

[Tuffers]

Had a customer question WFP this morning, saying that dark grey run marks were marking and staining her sills. The house has newly painted wooden frames, which are clean. Windows are also kept on top of, there are no black seals around the glass. Why are the runs appearing? It also happens on some uPVC too.

Any thoughts folks?

I have no logical answer. First thought was black rubber seals, but there are none. Are they hiding

Is there a gap between window frame n sill that dirt has got into n with water about just causes runs?

If its a one off incident n only affects her, is there teenagers in the house chuckin stuff out? Or a cat, they climb walls.

could it be water hittin off top of the window structure n dripping down? Sure its not.

Is it from the wfp brush deteriating maybe, probably not.

Need to phone the WFP police i think. Does Mr.Gardiner know anything on this issue?

look forward to a proper answer, all the best.

Maybe the water is mixing with a chemical in the paint? I dunno, but I'm getting the ladders off next clean to have a go at the stains.

are they single glazed or dg units in those wooden frames?

running rain water possible vents

Double glazed.

Could be. What I'm going to do is trad the job next time and maybe the job after and clean the marks. If they come back, then it won't be WFP that's the problem. Her painter planted a seed in the custys head by saying the pole thing is making the marks and the window cleaner needs to go back to bucket and sponge (the tw@t). Then if the marks come back doing them trad, I can blame the painter /emoticons/smile.png.

Had exactly same thing happen......first clean after frames painted. Took a fair bit of work to remove them, but since then WFP been no problem, but always give these extra rinse to be sure. Painter said due to WFP, but as no ongoing problem, I reckon it may have been poor workmanship on his part!

Ah its gotta be rain water in my mind, what type of brickwork is the house made of? I reckon its similar to a permanent water mark on a window where two openers are above a large pain, you always get that stain.

Rain water is dirty and contains minerals etc, if it hits brickwork then makes it onto frames/glass it will have picked up more contaminates to deposit onto white/clean surfaces.

I am running several long term experiments, a few of my houses have had new white pvc windows fitted since i have been wfp and i blitz them every time to see how long i can keep them looking brand new, when tradding no matter how well you wipe the sills etc you will always eventually get the black lines

Its been 14 months on one window and it still looks like its was fitted last week, the others are less than 6 months and are the same.

I really dont think its anything you are doing bud

No brickwork @keir, it's rendered. Suppose it's an easy excuse to blame WFP due to the amount of dripping water. Like I said, I will be tradding it for the time being to see what the results are.

Must be your fault then as the painter said so /emoticons/biggrin.png

All white window frames & sills being painted wood or plastic will eventually get staining from contaminated/dirty rainwater runoff. Windows are designed to keep the wind & rain out after all and are not maintenance free.

I used to blame the rubbers, but I have also noticed the same thing with newly installed UPVC windows as well as wooden window frames with no rubber seal around the window. I cleaned some black lines off one clean I did after the windows dried. On the following visit I noted that the black streak lines were back.

So I have now concluded that whilst deteriorating window seals are part of the problem, atmospheric polution combined with rain is also to blame. It is not my problem. If the customer thinks or insists it is, then we mutually agree to part business company.

Some people are looking for an excuse to make a mountain out of a mole hill, especially if there has been an expense like repainting window frames. If they aren't happy, just move on - easy for me to say as I'm over subscribed with customers at the moment.

ps. I have also noticed that the lead trim above bay windows can also make the black/dark coloured streaks on the plastic/wood as we all well know.

I also think the quality of the paint isn't as good as it was a few years ago. Going to water based, none lead added paint has had it's downside. Even the top paint manufacturers have had issues, ie Dulux.

Totally agree with the lead roof above a window @spruce, it makes a right mess on the glass. Also, how much water do we put on the window compared to the amount of rain we get in 4 weeks? Yes she spent a fortune on the painting. I really hope the lines reappear after doing it trad and I can blame the painter for using cheap paint. She also pointed out some wood knots are starting to show through the paint work. I will be cleaning in just over a week and will keep you updated.

ahh wood knots defo painters fault./emoticons/smile.png

 

[Tuffers]

Well, here we go. A first clean done today, never been cleaned ever. The house was renovated and hasn't had the windows cleaned in all that time, until today. Guess what? Black water runs on the white uPVC! WFP to blame, my arse!

 

[Smurf]

I'm sure I can still see grey streaks on those frames. If your going to do a first clean do it right @Tuffers /emoticons/biggrin.png

 

[Tuffers]

Ahh, but what caused the streaks? Buggered if I'm going to get them off. I did point out to the custy that they were already there, just so I don't get the blame in the future /emoticons/wink.png

Half a job :laugh:

That why I charge alot more on one-off/first cleans as I also restore the upvc aswell back too white.
