Condesation on the bedroom window

katy67

Hi,
can anyone help on this or know someone or company who can get rid of the condesation on the window. 1 bedroom window is so bad, we can't see out the window. Since we got the bad snow 2 years ago, it got worse. The window is always opened during the day and also the vent except they are closed in the winter but it made no differences. The window is double glaze and it in between the 2 panes. We also put insulation in the house which probably didn't helped. We live in a 4 bunaglow built 1998. Ideally the window should be replaced but can't afford to that. Have been looking up on the internet and have come cross defog company, etc which they come to you and drill holes in the window to clear the window.
Is there any company like that in Ireland?

so its between the two pains AND on the inside as well?
for the internal condensation, its a combination of poor ventilation and the window unit not keeping the internal surface warm enough.
with the condensation between the two pains: imho change the window..

well, i wouldnt blame the insulation

if its happening between the panes then the window has failed. the gap between is suppose to be a vacuum but now obviously is allowing air in. Any remedial measure other than replacing the window would just be a stop gap for now and not a long term solution.

however id suggest (assuming its a pvc window):

1. applying a thick bead of silicone all around the window on the external, to try and reduce the air flow into the window frame.

2. is the affected window is an openable and not a fixed pane, id also apply a thin bead of silicone between the glazing and the frame all around the window, both inside and outside.

3. pull thick heavy light coloured curtains across the window early in the evening. if theres a radiator under the window, dress the curtains behind the radiator.

4. check the rubber seals around the window. if its a pvc window the frame could have warped, which tends to happen. Does the window feel draughty on a windy day? It may need the seals replaced.

5. run a bead of caulk all around the window between the frame and the plastered wall. also run a bead of caulk all around the window board and the plastered wall. You should do this on every window in the house.

Theres also the option of fitting an insulating shutter to the external wall and closing it at night time to trap warmer air between the external and the window... but id focus any extra money into changing the window

It's not the window, its the glass. A double glazed unit, does not have a vacuum, just filled with Air, or possible Argon, its the seal, around the edge's, which has gone and is letting in moisture. They only come with a 10yr guarantee

If the condensation is between the glass, just look up Glass in your local Golden Pages and get a price to replace the Glass, not the window.
Poor fitting windows, drafts etc actually cut down on condensation.

For condensation on the inside look for the source of steam in your home, cooking, bath, showers etc and insure those areas are well ventilated, its the moisture in the air coming into contact with a cold surface and turning back to water.

If you can afford to replace the windows fair enough, but this should be a simple, and cheap solution.
