Windows: gap in corner - problem?

[£15]

We've had most of the windows in our house replaced, but not all by the same company. The latest replacements were done by 'company A' and I am comparing the finish in the corners, where the (internal) beading is cut, to the other companies.

We're not happy with the gap. It looks poor. Also, when the windows mist up (showers, drying clothes, etc) there are little clear areas (imagine an elongated pear shape) eminating from the corners which, to me, suggests a draft. None of my other windows do this.

The company have been out twice to inspect the work and claim it's the type of beading used and just how the machine cuts it. (In my mind I'd be cutting the plastic by whatever means, but trimming the rubber by hand so it matches.) The suggested remedy is to use a different bead. However, due to the shape of the window at the top, it can't be used there. So we'd be left with the original beading up top and something different down below.

They're really dragging their heels on this. We reported it a couple of months ago. They called up this morning (after we chased them yesterday) to say they have to send someone out again to inspect.

Am I being unreasonable?

For the record - when showering/drying clothes our windows are open, we have an extractor fan in the bathroom and a dehumidifier on the landing.

Window fitters are coming out next Wednesday to take (another) look.

Since moving into our house in May 2014 we've had several tradesmen in for various jobs, e.g. electrics, windows, gas-fitter, builder and they're all great to get on with and appear to do a great job - but after they've gone and a few niggles start to appear after several weeks, they take the ****: excuses, too busy, we'll be out next week, that's ok, ignore calls, don't call back. It's true what they say - once they've had the money...

Having said that, we've had one guy who went above and beyond and was a true, old-fashioned, total pride in his work, tradesman and he was the guy that fitted our multi-fuel stove a couple of months ago. If you're in Liverpool (and, I imagine, surrounding areas to an extent) and need a recommendation for a stove fitter, let me know.
