Double Glazing Unit Condensation / Blown DIY Repair.
In this video I repair a failed Double Glazing unit that is suffering from severe internal condensation and damp. The unit was misted in the lower portion due to the water ingress. The glazing was taken apart thoroughly cleaned and resealed this process took some time (circa 5 Hours).
Thanks for watching why not Subscribe to learn of more repair possibilities?

Fascinating, thanks! Really interesting to see how DG units are assembled. However, this definitely convinces me to always get a new replacement unit, this would finish me! Great job though, you've done. 🙂
Kudos for doing this mate. I’m not sure if id have the time to do this, but a good option for those who do. I tend to just replace the whole pane, but there really should be a better/easier way.
Absolutely brilliant better and cheaper than employing window people thank you looking forward to more quick cheap fix.
More will follow Robert in the course of time!
It's unlikely to be better than a new unit and if you can take the unit out and refit it you don't need a window company, just get a new panel made by a local company and fit that.
Another point to consider try and do it outside in good dry weather. Working inside in winter with all the heating on is more humid than most imagine. Then that humid air will condense inside the unit again after all the hard work. Great video, just a pointer for anyone thinking of doing it, better to wait for a dry sunny summer day! Also, the glass edges are razor sharp just as they were cut in the factory - no edge grinding is done, very sensible to wear some protective gloves.
Too true regarding the weather I like to pick out the sunny warm dry days but on this occasion the weather app lied to me!
Better quality windows wouldnt have bent spacers. They would instead have all cut spacers, all filled with desiccant and conected at each corner with those corner connectors. All in all very well done. Saved yourself alot of money. Here, near Tacoma Washington, a new twin glazed unit that size would be around $500.
Having made DG units myself on a DIY basis in the past I can say that by far the hardest job is cleaning the glass in the viewing area!!! Mortifying to notice smears, bits of debris and other imperfections on the inside surfaces while installing the finished unit into the frame.!!!
Check and double check then keep checking again, a good eye is required in conjunction with good lighting!
Hi , what do you use instead of the hot melt to seal the units together, ? Someone recommended this Puraflex 40 PU Sealant & Adhesive , would this be ok ?
Matey youve given a lot of people an option they didnt have before.....all these nay sayers should jog on....I recon the whole sealed unit industry is all smoke and mirrors....sealed, gas filled, argon this argon that, cut your hands, slice your fingers off etc etc ..ffs what a load of tosh....its 2 bits of glass stuck together with silicone....pure protectionisum of the industry....well done I say, Im going to do it as a seriously good diy-er, semi pro handyman etc util I saw this I thought it was beyond me because of vacum talk, fancy gas talk but going by the veiw out the window, this fix will be more than good enough for me...well done again
Thanks for taking the time to compose such an uplifting comment,I have endured a lot of criticism for detailing this and the other double glazing repair video I made! I totally agree with your summary. FYI I repaired one in mid 2020 that’s still good including both of the ones I recorded , it’s a French door so it’s big and costly to replace! Wishing you all the best with your future repairs.
Agree with you 99% apart from the silicone bit. Silicone is not 100% vapour proof and over time will allow moisture through which will condense on the glass; more so if inert gas is present in any significant degree. For DIY jobs use two part polysulphide (as opposed to hot melt sealant and equipment).
@@jesserawson898 , would this be good to use , Puraflex 40 PU Sealant & Adhesive, ?
Inject acitone between the silicone & metal frame. You will find the silicone just peels away. Agree you require to make edges & inside panes spotlessly clean. I also used white vinigar and baking soda, also glass cleaner. I clamped the pains together while filling outer edge with silicone. Moving one clamp where necessary to inject silicone. Note: do not over tighten clamp. Requires just enough to fix internal frame in position and hold glass faces in close contact while injecting silicone. Use old credit card or similar to smooth and spread silicone. Use good quality thick gaffa tape around edge to keep silicone in place.
Nice job man! Suggestions: use a single edge razor blade to clean the initial sealant residue off the glass.
Seal the window as you showed; you can use the side of a spoon to get it even. A concave finish is ok and tends to work better.
Let the sealant skim, and if you can wait, firm up. Then clean the excess off the glass with the razor. Then put your gaffers tape on after wiping the glass down with denatured alcohol or acetone. Again nice job getting it done!
I’ll take on board your tips thanks.
I can appreciate what you took on as a challenge. But it does take a lot of time and patience and even luck to accomplish that task. Seems most windows these days come with life time warranties. So for older windows that don't have such a warranty, it could work out. But each person has to review the risk and possible problems when doing it. Could even go a step further and pull a low vacuum on the finished window before reinstalling in the opening, and than fill the inside with nitrogen to stop future moisture infiltrating again. Thumbs Up!
Could I ask where you get these "lifetime" warranties?
Thanks for this. Glaziers should offer a refurb service themselves but I guess selling a new window is more profitable. Capitalism rewards consumption and penalises conservation. Throwing away perfectly good glass just because the seal has gone is nuts.
Thanks for the video. I've replaced numerous blown units over the years because they were relatively cheap (if you went to the right place) but now like everything prices have increased.
Door units have to be toughened which doubles the price so I'm definitely going to give this a go on my french doors 👍
Any info on the longevity of this type of repair?
I repaired a French door glazing unit, it was the second one I repaired as I did a smaller window first as proof of concept which went reasonably well. I repaired both windows in the summer of 2020 during the pandemic off the camera and they are both good to this day.
Do you do repairs?
@@camsmith931 Yes all the time but only my own family friends items etc.
Great video. I have to do about 80% of the windows in my house. I will probably buy new spacer bars and Desiccant as there is green fungus stuff coming from the existing. Can you recommend a supplier?
Best of luck I’d start small given the choice , I suspect new dessicant and spacer bars could be a tall order to fill .
@@TheRepairer Yes I had it in mind to do one in particular. A supplier said they could do a pack of 80m of spacer bar and 25 KG of Desiccant. I think I will start a production line.
@@theophobia-uk They are some serious quantities!
Hi, i wonder if you could help pls? I took this small first unit out of oir conservatory. Stripped it down, cleaned glass throughly and used clear mastic to seal before gaffa taping all around. I struggled to get all the beading back in, but it misted up AGAIN within hours! Where did i go wrong pls? Tks v much. John
Did you dry the desiccant out of the internal frame, if not that will be your moisture source.
A replacement unit would cost about £32 and comes with a ten year guarantee, taking in two tubes of sealant you can save £27 doing this yourself if you have a whole day to spare. Cutting the glass open is extremely dangerous often leading to slashing your opposite arm holding the glass which is why glass companies not longer offer this service.
£32 or thereabouts isn’t the price available to the general public unfortunately.
Uhm... i'm just wondering. Normal double glazing is filled with a gas and does not contain any normal air inside (this keeps it from fogging up or have water in it as air contains water particles and by removing the air and inserting a gas this is not possible). How to get this gas back in? Fogging up usually means the gas has escaped. Also having 2 panes of glass with air instead of a special gas between them does not make them isolate the cold from outside... as normal air just heats up and passes the cold to the inside panel. It's not as if you have 2 panels of glass it will isolate.
Dehydrated Air is used in common ore garden double glazing units like the one in the video.I understand there are gas filled options available at the higher end of the market and it’s the sealant between the panes that fails causing internal condensation. Trapped air is also an excellent insulator. Thanks for viewing.
just replaced one at my home, glass company usually supplies windows filled with air or for a little extra filled with argon gas.at least in UK
Just have a new panel made and save your whole day. This is way too much work to save a few quid
The true relevance is at what rate do we exchange our finite time for cash, costs are to be paid either way.
dont even tried this, way tooo much work ,time waste.Tried myself and failed. lucky me as found small glass company in Kent which supplied me with ready made glass unit, gave them measurement . .140cm x 90cm just for £70. Fitted myself in old aluminum frame. Other window people wanted £220 +vat for replacement, by them.
Sorry to hear you unfortunately failed to repair the double glazing unit, I find that quite odd as I have successfully repaired four consecutively that are are still good to this day.
That’s not a considerable amount of moisture, I had a blown window that had 6 inches of water between the panes, it was the clearest part of the window😂
6 inch of water is shocking, that must have took an age to build up!
Please nobody try this. If you are competent enough to remove the beads, just measure for a new unit. The removal of the unit and checking the drain holes were good bits of advice 👍🏻 Everything else in the middle, dont bother, too much can go wrong like cracking the glass, bending the spacer bar or serious cuts.
It’s achievable for a competent DIYer.
@@TheRepairer achievable yes. Advisable no.
whilst you think you have a point, people could at least try it which costs nothing apart from time, if it really went boobs up then a new unit can be bought. many ways to glaze or temp block window until new unit arrives.
My husband would do this..he old school kinda guy.. fixes the entire house. Why not be careful and at least try it save hundreds of dollars.
@mikeprunty1
I have a very small blown window in the conservatory, approximately 8 inch by 12. I feel confident enough to give it a go. I was surprised how straight forward it was. At the end of the day if I mess up I can buy a unit. Having worked in an environment which was considerably dangerous I am well aware of health and safety, personal protection and also lone working. This is definitely a project where another person watching or helping is mandatory. The conservatory door is also blown, I definitely will not be repairing that. That, I think, is well above my pay grade!
Please, don't even try this,this blokes nuts..
Tony are you an appropriately certified person? to be passing this judgement on my mental health!
@@TheRepairer been a glazier for 30 years,if people follow your instructions they will cut their bollocks off.why didn't you say put gloves on first..?..

@@TheRepairer you didn't have the things on when you was splitting the unit.. that's fuckin dangerous to a novice,plus I did notice your cut hand..🤣
@@TheRepairer don't mean to be a tit,but honestly, I've seen people almost take their finger's off splitting units..i know your only trying to help mucker..
Jesus just buy another unit
The imparted knowledge of how to repair one is evidently wasted on you.
Takes 10 minutes to replace the unit with a new one, this messing around with an old unit isn't cost effective, it will be the same in a few months, I have replaced thousands of units, why bother with this
They last for years that’s why I repair them and it isn’t a ten minute job.
Here is how a DIY replacement would work 1) remove beading to accurately measure the failed DGU length x width depth. 2) Contact glazier for replacement prices and engage one. 3) Refit window beading and wait days on end for it to be produced. 4) Collect DGU unit from Glazier in a suitably sized vehicle. 5) Remove beading and fit the replacement unit. 6) Dispose of old DGU somehow.
It's my home and my window in the video, the repair has lasted 10 months. No one has noticed it was a repair instead of being replaced and tradesmen have stopped knocking on my door trying to rip me off.
