Where would i find the 'window cavity seal'?

The worry then would be...

Windows replaced, installed correctly...

still have damp patches on the side when it rains.

But there's only one way to find out if that's going to happen.

You have not answered my earlier post about what your damp proofing guys were doing near the window...so still a mystery there.

Be careful before going down the new window thought process. A typical scenario is damp proof guarantees are full of cop outs and exclusions. You remove plaster and install a new window, and the work done by the damp company has been disturbed. As such your guarantee becomes void.

This is also a standard clause with cavity wall insulation. Regardless, if your window(s) come out first check if you have cavities, then check if you have CWI, then check if you have a guarantee for it.

You are now getting a consensus of opinion inline with what I've told you by PM, I'm pretty sure we are right,

Also just picked up on the fact that the panes are misted, again often a sign of poor glass to frame installation, nothing to do with your leak just another indication that it's probably better to replace entirely.

The window will cause much less damage when removed from the outside, the render, I've told you this before, has to be cut out of the reveal to prevent greater damage when removing/refitting. Small amount of render the patch up afterward and minimal internal plaster work.
This is the only way you are going to get to the bottom of this, plus you will get more efficient windows

I have said before cyclone is a switched on guy. In an earlier post I mentioned the windows were old and poor quality. The misted panes will be a reflection on this.

Now I am chancing a difference of opinion. Pvcu windows are meant to, or perfectly capable of, being installed from inside a house. This is because they are designed with internal beads, like yours are. So your windows were probably installed without damaging the render.

You can check this out, but the bottom line is I would not disturb the render. I would replace the windows from the inside. Whilst doing so, repair any existing render damage or damp, meticulously make good the cavity closing detail and act dumb over damp proof guarantees.

Peering at your first photo, it's just possible that one can see that those windows were installed from the outside, without disturbing the render.... so there's every chance they were poorly fitted, in order to squeeze them in and not need to patch the render. It's difficult to be sure, but it does look a bit like that...

I don't know what happened to Steve (keystone) he stopped answering my texts & calls at about the same time as he stopped posting on here

Just had word back from a window installer who my wifes workmate used & totally recommended.

They don't do repairs, but to totally replace those two windows - supply, fit etc is just a tad over £600.

Not bad i thought.

I should've asked them but i don't want to pester them with minute detail every 5 mins, that's what you guys are for .......... does it cost more for trickle vents to be included?

I don't like the look of them to be honest but it does get quite a bit of condensation on the inside in a morning depending on the time of year.

Not that you'd notice.

Yes, we were all on the same wavelength, I don't know anyone who was correct on more subjects than him, shame he isn't here (for me to argue with:rotfl:)

Problem is that swapping from the inside is massively more destructive to the decor.

The plaster in the internal reveals has to be hacked out, trouble is this often extends as far as the side beads, ie, you end up damaging the beading and plaster on the internal wall as well as the reveals.

Yes, they can be installed from either side, the revel is usually parallel. ie no step. it's just that less damage results from external installation.

There will be exceptions but can't think of many other than one where the external reveal was smaller than the internal, ie the window fitted from the inside up to the outside skin, but this was a 92 solid wall rather than cavity construction.

Seems quite fair, very fair infact, ask him how he stops the issue we think you have, BEFORE YOU ORDER;)
