How to Replace window pane Window Panes

A cracked window pane can be a nuisance. This can be an opportunity to upgrade to energy-efficient windows or insulated ones to enjoy benefits such as improved comfort, higher resale value and reduced utility bills.

You can do it yourself for less than what it would cost to employ an expert. You'll need only the right tools and a few hours of your time.

Glass

If your single-pane windows are outdated, deteriorating or broken replacing them with more modern glass that is tempered or insulated will improve energy efficiency and reduce noise while preserving the original character of older homes. A majority of homeowners with hand tools can replace windows with ease. You will also require an extra replacement window glass pane, glazier's tips, pliers, and latex glazing putty. If you need to you may make use of a heat gun to warm the old putty. Wear safety goggles and gloves prior to starting. Working with broken glass could cause serious injuries.

Begin by removing any broken pieces of glass. This is best done using the help of pliers but a flathead screwdriver may be used in the pinch. Utilize a wood chisel or putty knives to remove any old putty that remains around the frame and window sash. Be careful not to scratch the window sash. Work slowly and carefully. It is recommended to do this using a sturdy ladder instead of the ground, and to have someone stand below the sash to help hold it steady.

Make sure the window frame is ready to receive the new pane once you have removed the old putty. Find the width and the height of the opening in the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be taken to an hardware or [Redirect Only] home centers store to have cut a piece of glass that is in stock to the correct size. You can also cut the glass yourself, if you have the appropriate tools.

After installing the new pane, run a small bead of caulking around the edge to make it weatherproof. Then, you can install a glazier's pointing on each side of the frame to hold the pane in its place. The points should not be so tight that they create friction between the sash and the frame but they shouldn't be loose.

Before applying the putty, work it in a gentle manner until it's soft and free of lumps. Make it into pencil-sized strips. Place the first strip in the corner of the frame, working from one corner to the next so that it is smooth and even.

Glazier's Points

The glazier's points are small triangular pieces of steel that help secure the glass to the frame without causing any damage to the fragile surface. It's simple to learn how to use this nefarious tool, and you'll save money on the cost of a professional installation.

After the old putty as well as the glazier's point are gone Clean the frame thoroughly using a utility knife to eliminate any remaining traces. Lightly sand the frame in the rabbet grooves if needed to smooth rough areas. If you decide to sand wood, protect it with painter's tape to prevent accidental damage.

Measure the empty frame's dimensions and write down accurate measurements. Take these dimensions to an hardware store or home center and have the new pane cut slightly smaller than the frame's opening. This will ensure a secure fit and leave room for expansion and contraction.

Place the new pane in the frame and press it down using your hands. Then use the point of your chisel or back end of the putty knife to pierce the glazier's points as shown in Figure 11. The glazier's point should be flush against the top edge of your pane and the shoulders should be just below that lip.

Apply a thin layer of glazing compound over the edges of the new glass and in the rabbet grooves, to seal and protect them. Allow it to dry and cure completely.

Once the glazing compound has dried it's time to put in the new window sash. The first step is to coat the wood with an even layer of linseed. This will stop the new putty drying out or cracking as it absorbs moisture. Apply this coat with a brush or the edge of your putty knife, then use the chisel or the back end of the putty knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball thrown or a rock thrown by error, or a fallen tree can cause a broken or cracked window. Fortunately, the majority of windows can be replaced by simply putting a new piece of glass in its place. The glass is held in place by a small metal clip, called a glazier's point and putty. This compound is also referred to as glazing compound. Before you install a new pane, first take out the old one and clean up the area using the help of a rag, the pull-type paint scraper or the wood chisel. Wear protective glasses and gloves while doing this work. If the window is glued to the frame, you'll need to use a heat gun to soften the adhesive prior to prying it free.

If you plan to reinstall the original sash, gently remove the molding pieces that are used to secure the old pane. Then, sand the sash to ensure it's level and ready for a new caulk. Once the sash is reinstalled it is possible to apply a silicone caulk to the glass. This will ensure that it won't get soiled or discolor over time.

Remove the glazing points from the rabbets, or the grooves in the sash, where the glass sits. If they're difficult to cut out, you can try holding the hand tool, such as a heat gun over them to soften them first. When using a heated tool, be sure to avoid damaging the sash's railings and sash.

Prepare the bed for your new pane after removing the old glaze points and putty. Roll a rope with glazing compound between your fingers and make it about 1/2 inch thick. Then, press it into the rabbets where the glass will sit. It is essential that the glass is positioned against the putty on each side, so if you need to, lightly tap the glass into the rabbet using your thumb.

If the new pane is cracked, you can use the silicone caulk or Replacement Windows Prices glass glue made from solvents to cover the crack before pressing it into the sash. Otherwise, you'll need to apply putty over the crack to form a tight seal and keep water out. Once the putty is dry remove the oily film from the glass and allow it to dry completely before painting. If you paint before the putty has completely dry, it will not form a solid seal and could be leaking or discoloring in time.

Paint

If you've experienced a broken window pane, then you may be worried about the expense of replacing it. However, replacing a single glass pane doesn't need to cost a fortune If you can do it yourself. Even a double glazing window replacement-paned window can be replaced at a fraction of the cost it costs for a professional.

First, if you are working on a large window, make sure it is securely fastened to the frame. This task can be made relatively simple and fast with the proper tools and techniques.

If you're ready to begin, begin by removing the old window pane by removing the glazing points made of metal that are attached to it. These are tiny triangles of metal which act as "nails" that hold the window in the frame. They are buried beneath a layer of glazing putty, which transforms into a solid moulded wedge that secures the window in place and conceals the window's points.

After you have removed the old pane removed, clean up the surrounding frame and wood. Scrape away any paint and sand down the rabbet grooves where the glazing points were. Sand them down to clean wood surfaces, so that you can paint the frames the same color. After sanding, apply a layer of flax oil to the bare wood to extend the life of the frame.

Next, measure the size of the window opening. You will need to measure the horizontal and vertical dimensions of the entire opening as well as the thickness. Subtract 1/8 inch from each measurement to ensure that you get a precise size for the new pane. This will also allow for expansion and contraction of the glass during seasonal changes. You can take these measurements to a hardware store or home improvement shop and have the glass cut for you.

Now, it's time to bed the new window pane. To do this, place the pane inside the frame and move it around until a 1/16 inch of putty remains between the edge of the glass and the sash on all four sides. Use a putty knife to smear the putty evenly, making sure that there isn't an excessive amount of excess putty in the corners and along the edges. When the putty dries, it can be painted with the same color as the frame to prevent water and air from leaking into the frame and causing fogging.
