paul1966 Posted April 3, 2019 Report Share Posted April 3, 2019 Two of our windows have gone misty due to the seal going, looking online i found a website that repairs the windows by drilling two small holes in the glass and fitting a valve of some sort when the windows have dried out, i have found a ebay site selling the kits but has anyone tried them? its £35 and should repair four windows. i would think the kit is about half the cost of new glass for the two windows i need doing.

ph5172 Posted April 3, 2019 Report Share Posted April 3, 2019 I have seen similar things on caravan windows. Maybe cheaper to get a drill bit for glass(?) and buy a pack of those. Quote Link to comment Share on other sites More sharing options...
12gauge82 Posted April 3, 2019 Report Share Posted April 3, 2019 It won't work if your glass is toughened, it'll just shatter. Quote Link to comment Share on other sites More sharing options...
panoma1 Posted April 3, 2019 Report Share Posted April 3, 2019 It won't cure where the sealed unit broke down in the first place! Will it? My next door neighbors have had a couple of double gazed units repaired, you can't clean the inside, so the water condensation stains can't be removed.... I bought a new DG unit when mine broke down!

TIGHTCHOKE Posted April 3, 2019 Report Share Posted April 3, 2019 Always replaced when "blown" How would you regain the vacuum? Quote Link to comment Share on other sites More sharing options...
paul1966 Posted April 3, 2019 Author Report Share Posted April 3, 2019 i think the idea is that there is no vacuum and the valves allow air in and out so stops the mist build up, any way i think i will replace with new windows anyway.

Surely if there is no vacuum, the window is far less efficient! Good idea to change the "blown" ones. Quote Link to comment Share on other sites More sharing options...

Dougy Posted April 3, 2019 Report Share Posted April 3, 2019 I have 2 gone, they will be replaced by double glazed units. Not by a couple of holes and a who flung dung wing ping bit of plastic. Quote Link to comment Share on other sites More sharing options...
Bigbob Posted April 3, 2019 Report Share Posted April 3, 2019 The wife got our windows fixed instead of replaced , they replaced 2 units that the seals where goosed and did the seals in the rest £1200 , instead of £5000 to replace them all Quote Link to comment Share on other sites More sharing options...

figgy Posted April 3, 2019 Report Share Posted April 3, 2019 Of they're not stained inside just remove the unit, remove the foil tape and re-seal the edge of the unit with silicon sealant. Re tape and see how it goes, for less than a fiver worth a try. Quote Link to comment Share on other sites More sharing options...
Dougy Posted April 3, 2019 Report Share Posted April 3, 2019 Just priced up for a unit 900x900 laminated £95, standard was £65, then the cost of the fitting. Quote Link to comment Share on other sites More sharing options...

Saltings Posted April 3, 2019 Report Share Posted April 3, 2019 sealed units overall measures in thickness are 4 ? 4 the overall thickness is important when ordering replacements the repair kits I don't know modern day dg are argon filled most dg failures is down to an external weight load on the glass by insufficient packers/ spacers and the upvc frames carrying the weight that timber frames did also in direct sunlight / heat for most of the day cold at night (temperature extremities) leads to failure instead of buying glass drilling kits as a repair remove the sealed unit and drill holes into the bitumen spacer to get air circulation / drainage will give the same effect but without the thermal value only a bit of time involved minimal cost or new sealed units Quote Link to comment Share on other sites More sharing options...

People are opting for a skin of tough and skin of laminate. Covering the breaking in side. We use argon and krypton gas sometimes but boy that’s expensive .

TIGHTCHOKE Posted April 4, 2019 Report Share Posted April 4, 2019 An interesting thread, I shall ask the boys that make our units what they recommend and if the repair kits with the valves work at all. Every blown one I've ever seen has been replaced rather than repaired. Quote Link to comment Share on other sites More sharing options...
paul1966 Posted April 4, 2019 Author Report Share Posted April 4, 2019 I'll try drilling the bitumin spacer first, got nothing to lose so worth a try. I wonder if its possible to replace the desiccant inside the frame at all. Quote Link to comment Share on other sites More sharing options...

I am sure the op meant would fail over time, we have been in our house 14 years and the windows were fairly new then. So far we have had to replace one large window, south facing funnily enough and now have two smaller windows gone so i am sure over the next few years we will be replacing a few more.

The living room and upstairs bedroom windows glass was replaced there 12 foot long maybe 4 foot high all the rest where taken out seals replaced and re installed another 12 windows all the house apart from the porch i built that 5 years ago and those windows are still fine . When i bought this house the guy was proud to tell me he had the windows built to his speck they weren't worth a damn i've blackout blinds in the bedroom as i do night shifts and the wind used to rattle those about on a windy day no longer and its cheaper to heat the house now . Really pleased with the result boys started at 8 am and by 6 pm they had cleaned up and ready to go and far cheaper than replacing all the windows with new double glazing Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted April 4, 2019 Report Share Posted April 4, 2019 Well, having spoken to a man in the know, he says that 12mm and below would be filled with argon, and above that krypton. None of the repair systems he has seen ever work and ultimately require replacement. Apparently one firm some years ago, drilled in to existing "blown" windows, injected a liquid and then drew it out in order to clear up the water marks. Then they sealed the holes. He is not aware of this practice still being used. Quote Link to comment Share on other sites More sharing options...

Krypton is used in slim line units to meet regs 👍 4/4/4 in our case for heritage work Quote Link to comment Share on other sites More sharing options...
