Windows\u00a0are an important facet of your home, so you want to make sure they\u2019re always clean, intact, and well-maintained. However, incidents occur that you simply cannot anticipate. Or maybe you want to replace the old glass in your windows with a sturdier and more reliable option. So we\u2019ve compiled a simple guide to DIY broken\u00a0window pane replacement. This is a fairly straightforward home improvement project that you can finish in less than a day.\n\n\n\nDIY Replacing Window Pane\n\n\n\nThe process of replacing your window panes is very simple if you follow these steps.\n\n\n\nStep 1: Measure Before You Order the Replacement Glass\n\n\n\n\n\n\n\nBefore you order your replacement glass, you want to make sure you have the correct size and dimensions. Take your measuring tape and measure the area where you will put the putty. Be as precise as possible and take multiple measurements to double-check if you can. Write everything down so you can remember it when you place the order.\n\n\n\nStep 2: Scrape off the Old Putty and Prep the Rabbets\n\n\n\n\n\n\n\nYou can start prepping your window frame for the installment. So remove the old putty with a scraping tool. Then take a brush to clean off any residue. You can also use a primer to lay the ground for the re-glazing. Knead your new putty until warm and malleable. Then knead it some more into long thin strands.\n\n\n\nStep 3: Apply the Putty and Install the Glass\n\n\n\n\n\n\n\nNow that your putty is ready, you can start applying it on the sides of your window frame. Push it with your paint blade and make sure it\u2019s in place. Then get your\u00a0replacement glass panes\u00a0and wiggle them into the frame. Next, take the glazier\u2019s points and apply two on each side. Apply pressure to make sure they stay in place. Follow it up with more putty.\n\n\n\nStep 4: Clean up and Polish\n\n\n\n\n\n\n\nWith a knife or a blade, clean up the edges and let the glazing dry. Once everything looks in order, get your primer and paint to finish off the window frame. If there\u2019s any excess putty or leftover film, you can use a dry cloth and some oil to remove it. And you\u2019re done!\n\n\n\nDIY Window Pane Repairing\n\n\n\nAn accident happened and now your windowpane is broken. Maybe it was a tree branch falling off, or your kids playing football. And now you\u2019re frustrated because it\u2019s one more thing to add to your list of chores. However, don\u2019t worry, even if you have no idea where to begin, this is a fairly easy project. It will take you less than a day and all you need is your trusty toolbox, and maybe some patience.\n\n\n\nStep 1: Remove the Broken Glass\n\n\n\n\n\n\n\nPut on some thick gloves and remove the broken glass. Some shards will easily come off. For the stubborn parts, you can use either a hammer or a heat gun. If you opt for the hammer, you should probably wear some protective goggles to protect your eyes. On the other hand, using a heat gun is safer. The heat will soften the glazing, which will make removing the glass much easier.\n\n\n\nStep 2: Clean the Frame and Repair It If Need Be\n\n\n\n\n\n\n\nYou can use a painter\u2019s tool or a razor scraper to remove the old putty. If some parts of the glazing compound remain intact, use your heat gun to soften them. Then go over the putty again with your painter\u2019s tool. \n\n\n\nKeep in mind that you want to be as gentle as possible to avoid ruining your frame. Once you\u2019re done, you can smooth out the wood using some sandpaper. Then, apply a tiny bit of linseed oil with a brush. This will prep the wood frame to bond better with the glazing you will apply later on.\n\n\n\nStep 3: Extract the Old Metal Glazing Points Out of the Rabbet\n\n\n\n\n\n\n\nFor this step, you want to pry the old metal glazing points out of the grooves in which the glass sits. Shave off the outer layer then use some sandpaper until there\u2019s only bare wood left. Get a brush and a paint primer. Then go over the bare wood to prevent oils from coming out of the putty. This step will help extend your glazing\u2019s lifespan.\n\n\n\nStep 4: Apply the Putty\n\n\n\n\n\n\n\nNext, you have to warm up your putty by kneading it. This takes a bit of practice and a few tries to get those perfect pencil-thin ropes. Once your putty is warm and supple you can start applying it. Start with the rabbets first until you fill them completely.\n\n\n\nStep 5: Install the Glass\n\n\n\n\n\n\n\nPlace the glass pane into the putty while applying even pressure on all sides. Keep pushing the glass with the tips of your fingers until it\u2019s in place. Make sure that there\u2019s at least \u215b inch (3mm) between the glass and the rabbet. If you notice any gaps, you can take the pane off, fill them up, and wiggle the glass in again. Now take your glazier\u2019s points and put two on each side of the glass pane, then two more on the bottom corner. Repeat on the remaining side, and don\u2019t be afraid to use a little force to hold them in place.\n\n\n\nStep 6: Finish and Clean up\n\n\n\n\n\n\n\nTake more thin ropes of your putty and push them into each side of your frame. Then put some more on your exposed rabbets until they\u2019re fully covered. Next, take your putty knife at a 45-degree angle, and smooth out the putty. Clean out the excess with your knife until the putty lines up with the edges of your window sash. Wait for it to dry following the manufacturer\u2019s recommendations. Now you can prime and paint the putty along with any exposed wood so you can have a polished finish.
