National Windscreens

Post by Allan T » Wed May 13, 2020 1:35 pm

Does anyone have any experience of National Windscreens? I've always used specialist MG garages to replace screens til now, but with those options closed I decided take advantage of the home-fitting service and reduced insurance excess and give NW a go. The first appointment was cancelled by C19. They've just rung to re-book, but won't do it as a home visit - I have to deliver the car to them, and leave it for two or three days.

Hi Allan
Is the car a Roadster or a GT?
The GT is fairly straightforward except for refitting the trim around the edges of the screen, which are easily damaged when taking them off and often need replacing. Underneath this is the usual rubber and locking filler strip.
The roadster requires the whole screen to be taken out of the car and the frame has to be dismantled to fit the new glass. This takes many hours and depending on the age of the car the 'official' way of doing the job is to remove the dashboard to get access to the bolts that hold the screen in place, unless you accept an amount of bending of the ends of the dashboard. Later (rubber bumper) cars are slightly easier as the dashboard was different and doesn't have to be removed if following the workshop manual. It is also unlikely that they can use the old rubber pads at the base of the screen as these are now likely to be perished, as is the seal along the bottom of the screen, which will inevitably lead to leaks.
I would check that NW really know how to do the screen on a roadster (or a GT) and they will use a fitter experienced in doing the job, as most screen fitters only know how to bond a screen into a modern car.
A friend of mine used a windscreen company (I don't know which) recommended by his insurers to replace the glass on his LE Roadster. Initially they said they couldn't do it, but after the insurers intervened they got a fitter to travel about 100 miles to do the job, which took a whole day. He was very happy with the result though.
There is a bit more information by someone who tried it themselves here: https://mgbforum.mgb-register.org/viewt ... ?f=4&t=453

Hi Peter

Thanks for your very detailed and helpful reply. It's a 1978 Roadster, so it sounds to be one of the easier options. And the windscreen was last replaced about two years ago, using new rubber all-round.

I remember reading about an experienced fitter from a windscreen company travelling a long distance and doing a great job - I think it must have been your friend's case - and was hoping for something similar. But after yesterday's call, it isn't looking so good.

Hi Allen,
I don't know how I managed to post my last reply to the other thread, but at least you have found it!
Cheers

An update on this one: I delivered the car to the National Windscreens Watford branch just after 8am on Tuesday 26 May, had a call from them around 3pm saying it was ready for collection, and collected it next day. Only driving the car in rain will give a truly useful appraisal, but the staff there were friendly and welcoming and courteous. So far, so good.
