That is rubbish and misinformation. While it is true that replacing the insulated glass unit is optimal, the cost is high and is most of the time not justified. A double window thermal isolation relies on low heat exchange between the outside air and the air trapped between the double windows. The small translucent rubber caps covering the holes will not make a major difference in the air exchange and insulation especially since your solution is re-using glazing bead guarrantee to create leaks through the frame ! Renewing the sillicon seal is a DIY and will last just as long as the scraped old one did. People like me who have this condensation problem want to get their windows clean and translucent again, the thermal isolation is not a problem in my climate. Second there is nothing cheap about ordering custom sizes double windows units. I have a half circle large window crown for example that will cost the price of a new car oem windshield to reorder. the service provided by this company can be an economical effective DIY with minimal tool and make a huge change in the window without spending big bucks which is what most people with that problem want to avoid. Your post is lurring them in the wrong direction as getting glazing beads in and out creates other problems.

@@ericastier1646The hole drilling fix will inevitably result in some loss of thermal performance. This loss can be avoided by replacing the sealed glass unit. And in the UK these units are almost all rectangular. A 4ft x 2ft typical unit costs about £100 delivered to your door. Getting someone round to do a hole drilling bodge will probably cost more, so why do it ? As for the seal, you seem to be talking about silicone sealant. Windows in the UK are sealed to the outside frame with rubber seals. These are attached to the frame and stay in place when the glass unit is lifted out. You then simply insert the new glass and put the beads back on the inside to hold the glass in place, pressed tight against the rubber seal. Maybe it’s different in the US, but nobody here seals glass into window frames with silicone sealant. We use factory fitted rubber seals for UPVC and putty for traditional single glazed windows.

@@SteveSmith-zo4ml ​ Repeating a mild lie twice does not make it more worthy. No significant thermal loss occurs from the holes especially if they are capped. Even uncapped you are still significantly better than a single pane window and the difference is infinitesimally small with a sealed two panes unit as proved by infrared thermal imaging taken of two windows one sealed the other not on the same wall in cold weather. Why would you pay someone to drill the holes instead of doing it yourself ? Any reasonable DIYer can do this on annealed glass. The economical factor is big when doing the repair yourself since this company takes most of its charges on labor. Furthermore if you buy new sealed units you can expect them to fail faster than your old windows lasted unless you also replace all the rubber seals which adds cost, headache to find the exact ones that fit your frame grooves (which most people in older house will not have specs for). As for the sealant, i believe it is the same system in Usa than UK. I meant epoxy sorry not sillicon at an added extra measure, the rubber seals are still used. Rubber is the best material for many applications. Bad rubber quality that is the main culprit for these condensation stains. Once humidity passes the external rubber into the second seal on the window unit, winter freeze will do enough damage to break the sealed units insulation. Good rubber in good condition should never stain your skin black when it ages unless it was exposed to corrosive cleaners or is a low quality synthetic rubber. Once you factor all of this in, and DIY, this repair makes sense both economically and down the road.

@@SteveSmith-zo4ml Steve i wrote a long second answer before this message but having problem with stupid youtube HQ censoring a technical talk, that's how extreme censoring has become by the leftist bolcheviks on here. Left this message in case they ghosted it.

@@ericastier1646 I don’t mind having a discussion, but this is the second time you’ve been rude to me. I don’t engage with people who conduct themselves in this way. Let’s just agree to disagree.

That's what i was thinking ...

A single pane window has an R value of 1. A double pane window has an R value of 2. What is not mentioned here is that windows often have argon pumped into them, and obviously this method is going to clear out any argonbut likely with the seal broken then the argon is gone anyway. IF it is actually much cheaper than a window thats one thing,but from what I've read the results are 'debateable'. I suspect it highly depends on the home. IF you have a pretty nice house which is well sealed and insulated and moisture inside the house is kept fairly moderate then it may work well. Otheres not so much. I'd check the warranty and make sure you are saving money. Where I live I checked with repair companies and they ALL say they will save you money by simply replacing the glass within the window frame, and I would have thought that you could just take your measurements to a big box store or manufacturer and get one made there for cheaper. I'll let you know in a few months because I've got numerous windows in our home starting to do this, and I"m a cheap AND poor bastard.

Instructions available on this? Thanks

No they cannot, you must be united statian to speak such nonsense. It is a major overhaul. United statians have problem being loosers so they claim that anything short of impossible is "easy" they are afraid of the reality making them look weak.

​@@masonjar706theres a few posts on here showing blown windows being saved using this method

Agreed this should be a DIY then it would make complete sense.

10 years guaranty for a hole

you still have to clean the accumulated condensation minerals fogging the window.

A hose 😁

water pistol

A faucet.

O that's the fitter

I think it was Ed Sheeran

It's not just about the money. I used to live with single pane and it's horrible in winter. So much moisture on the window constantly and the heating never quite felt right, because one side of the room would be warmer than the other. You could literally feel the cold coming through the window if your bed was near it. Since getting double glazed it just feels so much cozier. And here in Britain we pay the highest energy costs anywhere in the world, so the extra cost of double glazing will pay for itself in just one season I think.

Way more benefits to double glazing than simply saving money. Though saving money is a huge benefit.

You're wrong there, it is a significant difference in comfort and heating in cold season.

If there is air between the glass then it is noit working.

@@BigAL0074 - Why?

@@Benzknees Air helps the cold or heat move across the gap, hence the gap. Don't waste time on this rubbish.

@@BigAL0074 - There's always a gas of some kind in the gap, but as long as it's not moving & carrying away heat it won't be a problem. When checked with an infrared thermometer, my treated windows appear to be no lesser insulators than other sealed units I have.

Air between the glass does next to nothing and there's plenty of studies to show it. Still air vs convection

Get a dremel tool and do it yourself

Get these guys in…

Need to use a diamond tip cutter drill and some lube cutting fluid.

Thank you for your response. I tried it and it works great

Don't you need a filter to keep out dust, bugs etc? Also, is there a special kind of drill bit for this?

Use a diamond or carbide burr, or one of those arrow shaped bits from wilkos. Keep it cool with water while you cut and don't press hard.

if you have a window the same as the one in the video and you try to drill it i guarantee 100% that you will have a pile of broken glass on the floor. that unit is going to be toughened glass that cannot be drilled or cut and if its not toughened its breaking all glazing rules in uk [ fensa certas or building control] unless its laminated and that is highly unlikely. for the purpose of this video they must have changed the unit to a non conforming unit

You gonna get mugged

This is total SCAM only idiots will fall for this ! Making a hole in windows that are designed to be fully sealed to keep the cold out to improve the thermal isolation is just ludacris. You are destroying the window's isolation by making a hole that let's cold air in is the same as having a single window and that is a FACT ! The correct way is to replace the window to keep the correct thermal isolation and to keep your house warm not to make expensive useless holes in a window that will destroy your isolation quality of your windows and tell you that a hole in the window is good thing for the environment is a complete scam. You will be paying way less in heating by changing the window rather than having a hole in a window, that will take your heat out of the windows. People think before you watch and call this scammers. Making a hole in a window is the same as breaking the window or leaving is open forever. Don't fall for scams

tempered glass cannot be cut

Double glazed units fail because they heat up and cool down by a large variation, especially with large south facing wimndows (doesn't happen so much on north facing glass as the temperature disparity is less). They don't tell you that on Grand Designs with all those floor to ceiling whole wall glass units! The cheapest solution is to take the glass out, separate the two panes (without breaking them!), take them to a glaziers and get the aluminium spacer bar/desicant replaced. I've done this several times on my south facing conservatory.

@@chrislordnelson2325 is that a fairly easy task, or are you in the trade? Our large, south facing conservatory windows seem to be failing one by one - just outside of their 10 year warranty.

Plus what about the Desiccant, that's saturated and useless now too.
