If the sealant in your windows has broken, then you’re looking at two options, either reseal them or replace them. Many people believe that it’s time to replace the windows at this point, even though you can apply a new sealant to keep your old windows intact. A permanent double glazed windows fix for a broken seal isn’t possible, however, so replacement is often best.
There can be some early signs of broken window seals, for example, double glazed windows typically accumulate more condensation between their two window panes when a seal is on its way out. This is when vapour builds up on the inside of the window panes, meaning that cold air is definitely getting into your home. However, the main sign when window seals fail is when mist builds up in between the two glass window panes. If you can’t wipe it away then moisture has penetrated the vacuum between the glazing panels and it’s time for either repair or replacement.
Some homeowners try resealing their double glazed windows on their own. However, the job can be complex and challenging for a DIY novice. The best option if you want your windows resealed quickly and efficiently is to work with a professional installer. They will be able to restore your double glazing seals without any risk that the repaired double glazing seals won’t function properly.
However, resealing double glazed windows might not be a long-term fix. If your windows are old, then the window’s framework could start to crack and warp in poor weather, gradually weakening over time. As a result, the sealant becomes more and more vulnerable, and no matter how many times you repair it, the window seal will still fail. The bottom line is that you could just be putting off the day when you need to replace your windows and costing yourself money in the long run by delaying the inevitable. Faulty window seals equal poor sound insulation and thermal performance and that can mean higher energy bills.

What Are The Clues That Double Glazed Windows Need Resealing?
Your double glazed unit is only as good as its window seal and the reality is, that no double glazed unit lasts forever. Fitting new window seals can restore the thermal insulation and integrity of your double glazing, prolonging the life of the window before it needs replacement but it isn’t a forever fix.
Old windows are much more at risk of failure because over time, materials on single pane windows, especially timber frames, can deteriorate. As they wear, they are less able to protect the window seal and as the frame changes shape and cracks, it makes it much easier for cold air to penetrate your home.
Early signs of broken window seals include visible gaps around the seal. This may not mean the seal has broken but it does indicate that the sealant is coming towards the end of its useful life. Cleaning around the sealant can help protect it from further deterioration but it’s only a matter of time before the thermal insulation is compromised and the windows need resealing.
Draughts in your home are another classic sign that things are not right with a window seal. As the seal fails, the window begins to go out of shape, allowing air from outside to enter your house.
However, the main telltale sign of a broken seal is an unsightly condensation build up between the inert gas filled area between the glass window panes. Most people don’t know that the removable window panes are simply held in with sealant and nails and pins. When the sealant fails, their thermal efficiency does too.
Not only are the windows failing to perform with optimal energy efficiency, but they could be at risk of breaking or shattering internally. It’s vital to take action to repair the airtight seal or the entire window may fail.
Sealing Double Glazed Windows
It is possible to seal the double glazed windows sash yourself, however, you’ll need to be fairly confident and proficient in DIY. You’ll need some specialist equipment, such as a utility knife, a putty knife, silicone caulking, and a caulk gun.
Start by cutting through all the old sealant on the existing window pane with the utility knife; it’s advisable to ask a friend or family member to hold the glass for you to avoid any unfortunate accidents. Once the pane is loose, remove it from the window frame and clean off the rest of the old sealant with a smooth and steady motion using the putty knife.
Next, clean the window avoiding chemically abrasive cleaning agents and then when dry, replace the glass pane in the frame and apply the new silicone caulking using the caulk gun. Gently remove any excess sealant with a wet finger.
Replacing a window seal can be a tricky job, especially if the window gaskets also need renewal, and there’s a high risk of breakages. For this reason, it’s usually better to hire a professional window company with expert professionals who know exactly what to do. They’ll also have insurance cover in the event of any accidents and you shouldn’t void any warranties. You’ll have complete peace of mind that your double glazing seals have been correctly restored, and there won’t be any nasty surprises on your heating bills.
However, if your home still feels draughty and cool in cold weather then it might be that the problem is more serious. Newly installed sealant can break down again, allowing moist air in, sometimes after only a few months. In this case, it might be a better option to consider replacing your double glazing with new units.
Replacing Double Glazed Windows
Sealing your double glazed windows might be a short-term solution and as your windows age, it’s more likely the seals will keep failing. Not only might your sealant break again, but any part of the window could crack or break the older it gets. But, by replacing your old designs with brand-new double glazed windows, you’ll be sealing the future of your home, not just your windows.
New windows are highly durable, and the latest technology means they should last for decades.
With advanced double glazing and fully weatherproof profiles, they won’t crack or twist and the sealant underneath will have protection from the elements, ensuring it won’t break down. Plus, you’ll benefit from superb performance when it comes to thermal insulation which will lower your energy bills.
With a fully protected sealant, the window will be air and water-tight. As a result, the cold air won’t be able to pass through into your home, and hot air won’t escape. Because of this, your new windows will be thermally efficient and won’t fall victim to condensation either.
You’ll be able to save money on your energy bills all year round with new windows and end up recouping the cost of your investment rather than getting caught in a vicious cycle of repair costs and constant broken window seals. Your new windows will save you money in the long run.
Why not put the problems of your old windows in the past and benefit from bespoke new designs with insulating glass units that suit your home, provide better sound insulation, and lower your energy costs.
