Window glazing putty alternatives8/17/2023 ![]() Alternatively, you can buy a heat shield for your heat gun…but I found this to be just as simple. It will also make the surrounding paint bubble up. The heat from the heat gun WILL crack the glass if it is in one spot too long. ALWAYS put aluminum foil down over the area you are working. In the second picture above you see a very important key. busy so you can be sure to see what still needs to be scraped. Sometimes it comes off easily, and sometimes is takes some serious effort…but it’s always messy. ![]() Save yourself the frustration and plop down $20 for a heat gun.Īs you start scraping, you see how messy this is. Please bear in mind, I only know this because I wasted time trying. It doesn’t get nearly hot enough to soften the glazing. Also, the different angles on the top are very helpful for the different nooks and crannies you will have to pull glazing out of. I really recommend using this type of scraper. But for now, the vacuum, scraper and heat gun will get up through. ![]() Later we will be using a miter saw, and a couple other goodies. Outside of basic screwdrivers, these are your main weapons. This is the beautiful exterior quality I am dealing with. However, that will not be covered in this tutorial. You won’t get a better time than this to do it. If there is further damage to the window well (broken, or rotted wood) that should be repaired as well. Once it’s all cleaned up get it painted all nice and pretty. Clean out all the loose paint and glazing from the window well and surrounding internal trim (1, 2). Removal done! Now, CAREFULLY carry the sashes to your work space and we’ll get started on the fun stuff! Now pull the free upper sash towards you and unhook the sash cords and allow them to rest against the pulleys as well (4). This is usually the only “delicate” part of the uninstall. Be careful as you get to the bottom of the upper sash as there is usually a notch you will have to “flex” the trim around. Usually this is simply held in by pressure, no glue or screws. Next pop out the thin trim piece holding the top (back) sash in place (3). Allow the sash cord knots to pull back and rest braced against pulleys. This will free the bottom sash to pull out towards you and allow you to unhook the sash cords from each side. Pop out the bottom first to allow the mitered edge at the top to come out without breaking (2). SO…let me know what you think…įirst remove the 3 screws from each side of the main trim holding the windows in place (1). And also bear in mind that tight, restored old windows matched with good storm windows can be as efficient as many new double pane windows. Not everyone has the money to replace windows with new ones. Now, this process is somewhat more technical than slathering glazing, but the trade-off is a great time saver. We will be using 1/4″ square trim in place of glazing. ![]() From pull out to re-install, each window takes around 8 hours instead of 1-2 weeks. ![]() The process here is designed to be done in a weekend. The newer water based glazing products get mixed reviews at best, and you are still waiting up to a week for those to be ready to paint as well. Also, unless you use newer glazing products, you must use oil base primers that are more difficult and rather pungent. This is primarily due to the oil based glazing that takes 1-2 weeks to set up before it is ready to be painted and re-installed. The problem with traditional glazing (which I have also done of other windows in this house) is that each window, from pull out to re-install, is 1-2 weeks. Every time I open or shut my 100 year old original windows, the (probably also) 100 year old glazing and paint on the back (outside side) of the window breaks off in chunks, makes a big mess, looks gross, and ultimately the glass will fall out. If you have any DIY abilities at all, and are willing to put in the effort, you can do this. Feel free to skim through and only use what’s helpful. That means I took lots of pictures and provide lots of written details. Therefore, I am writing this as if you are an idiot who is intimidated and overwhelmed by the idea of redo-ing your windows yourself. I am however, an avid DIY dad who lives in a 100 year old home in Boston. I am by no means an expert…on most anything. ![]()
