replacing a polyplasic window diy or dealer

[Scout]

I have a broken polyplastic window, it looks like somebody at some piont has tried to gain access by jemmying the window, and has caused a small crack which is now starting to cause problem. I have sourced an new window and frame and I will be collecting it at the weekend, my diy skills are average is this job do able diy or should I let a "man that can" do it. I understand its a two man job, but I not 100% sure whats intailed,

A:take off inner frame, blind/flyscreen

B:get somebody to hold the window from outside

C: loosen (diagonally) the screws hold frame clips

D:remove screw and frame clips

E: ease out window from outside (using blunt blade if needed)

F: clean up frame opening

G: refit in reverse order double checking screws are tight but no overtight

is that it or have I missed something

Seal with non setting sealant like Hodgesons.

It's not rocket science, just take it easy.

If it is just the plastic pane that needs replacing do you need to take the frame out?

If you undo the stays and open the window beyond the horizontal position the pane may slide out of the hinge channel

I understood that there was a rubber gaskit built into the frame, do you mean it needs a bead of sealant to the exterior edge of the frame?

I did think of that, the frame has a slight dint at the bottom hardly noticeable but still there,

Even your skills will do that just take your time why get riped off by a dealer you can do it no problem

I think I would leave the old frame in if possible as long as it’s not leaking but that’s your choice the window pane replacement would not take long to do.??

There is. With a new window and seal no sealant should be needed. You will not need to help the window out - I removed the inner fixings of a window assuming I'd be able to go out of the van to remove it. If I hadn't been parked close to a tree (which caught it) it would have been broken when it hit the concrete drive. I took mine out because (after 20 years!) the gasket was allowing leakage.

I've replaced just the panes in a framed and non-framed Polyplastic window (ones in my avatar).

A 5 minute job (as described by lunarman above).

Not replaced a frame though and would imagine how hard the job would be depends on how it was fitted. I have the installation instructions from when I originally fitted mine, I'll attach below

Then I may be wrong. I've only worked on roof lights and all of them were bedded on mastic.

you might be right,when I get the window I'll look and see whats what, but Im sure the newer ones have a rubber bead and are dry fitted

it seems you were correct, I been to autotrail and picked up the window this morning all nice a new, but as you say it needs a non setting mastic to seal it as theres no rubber gasket, which is a bit of a bugger as I'll have spend age cleaning off the old stuff.....

seeing as I need to use mastic I'll wait till the weather warms up a bit befor fitting.

If you're trying to remove the old mastic and have scraped off the majority of it, the rest can usually be removed with petrol lighter fluid. Get yourself a couple of tins of it. ?

Just change the plastic window Phil ? why make life harder than you need ??

you can always do the frame on a nice summers day if you really need to ?

 

[pappajohn]

A good Bead of Sikaflex around the OUTSIDE.
While the window is out it may be an idea to fully seal the opening with mastic to prevent damage from any future leaks.
Just spread it on with a finger... It will prevent water getting into the wall structure.

i found white spirit the best solvent on the rooflights which were bedded on black mastic be aware its very messy i would sheet it all up with masking tape and polythene

I replaced the glazing only yesterday, it wasn't as easy as i thought but the window was a big one, 1300x550mm , it defiantly is a two man job there must a knack to it as took ages. Ill leave the frame for now and only replace if any water gets back up the bottom front where the jemmy bar has dented the bottom of the frame slightly, hopfully it will be ok
