How to replace Window pane Window Panes

A cracked window pane can be a source of frustration. This could be an opportunity to upgrade to energy-efficient windows or insulated ones and enjoy benefits such as improved comfort, increased resale values and lower utility costs.

You can do it yourself at a fraction of what it would cost to employ an expert. You only need the right tools and a few hours of your time.

Glass

Replace your single-paned windows with tempered insulate glass to improve the efficiency of your energy, reduce noise, and preserve the original character of your older home. The replacement double glazing windows of the window pane is easy and can be completed by most homeowners who possess basic hand tools. You will also require an additional window pane, glazier's tips pliers, and latex glaze putty. If necessary, you can use a heating gun to warm the old putty. Wear safety goggles and gloves prior to beginning. Working with broken glass could result in serious injuries.

Take out any broken glass pieces remaining. It is best to use pliers for this however, a flathead may be useful equally. Make use of a wood chisel or putty knife to get rid of any old putty that remains around the frame and the window sash. Work slowly and carefully making sure not to damage the old window replacement panes sash. It is recommended to work using a sturdy ladder rather than the ground and have someone standing below the sash to help hold it in place.

Make sure the window frame is ready to accommodate the new pane once you have removed the old glue. Take measurements of the width and 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 home centers store to get a piece cut of glass that is in stock to the correct size. You can also cut the glass by yourself if you have the right tools.

After installing the new pane, run a small bead of caulking around the edge to make it weatherproof. Then install a glazier's point on each side of the frame to secure the pane into its place. The points shouldn't be too tight as to cause friction between the sash and frame however they shouldn't be too loose.

Before applying the putty on the surface, you must knead it thoroughly until it becomes soft and free from lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from one corner to the next and ensure that it is even and smooth.

Glazier's Points

The glazier's points are small triangular pieces of metal which help to secure the glass into the window frame without causing damage to the delicate surface. It's easy to learn how to use this nefarious tool, and you'll save money on the cost of a professional installation.

After taking off the old putty, glazier points and any leftovers Clean the frame thoroughly using an utility knife. If necessary it is necessary to lightly sand the wood along grooves of the rabbet to smooth rough spots. If you do sand your wood, ensure you protect it by using painter's tape to prevent accidental damage.

Take the dimensions of the frame and write down accurate measurements. Take these dimensions to a hardware store or home center, and have the new pane made slightly smaller than the frame's opening. This will ensure that the pane fits comfortably and allows for expansion and contraction.

Place the new pane into the frame and push it into place firmly using your hand. Utilize the chisel's point, or the back of the putty knife to tap the glazier's points, as illustrated in Figure 11. The glazier's point should be in line with the top edge of the pane and the raised shoulders should be just beneath 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 completely and cure.

After the glazing compound dries, you're ready to install the new window sash. First, saturate the wood with a thick coat of linseed oil. This will stop the new putty from drying out and cracking due to the moisture it absorbs. Use a brush to apply this coat, or the point of the putty blade. Then, use the chisel that is on the back of the putty tool or the back of the handle to gently hit the new sash, or glazier's point into rabbet grooves. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball thrown, a rock thrown in error, or replace window pane a fallen tree could result in a broken or cracked window. Luckily, most windows can be repaired by simply putting a brand new piece in place. The glass is held in place by a small metal clip called the glazier's pointed and putty, which is often called glazing compound. Remove the old pane and clean the area using an abrasive, scraper that is a pull type or a wood chisel. Wear gloves and safety glasses while doing this work. You'll need a heating gun in the event that the window is glued to the frame.

If you are planning to replace the original sash, remove any pieces of molding that are used to secure the old pane. Then, sand the sash to ensure it's smooth and ready for a new caulk. After the sash has been reinstalled it is possible to apply a silicone caulk over the glass. This will ensure that it won't be leaking or fade over time.

Remove the glazing points in the rabbets. These are the grooves in the sash, which is where the glass is. If they are hard to chisel, hold a hand tool such as a heating gun over them for a few minutes to soften them. If you're using a heating gun, be cautious not to cause damage to the sash or its railings by using the tool too closely.

Once the old points of glazing and putty have been removed, make a bed for the new pane. Roll a rope with glazing compound between your fingers, and then make it about 1/2 inch thick. Place it into the rabbets, where the glass will be placed. It's important that the glass sits on the putty in all places on each side, so if you need to tap it, gently press the glass into the rabbet using your thumb.

If the new pane is cracked you can fill it with a solvent-based glass glue or silicone caulk before pressing it into the sash. If the crack is not sealed, you'll require putty to keep the water out. Once the putty is dry remove the oily film off of the glass and allow it to dry completely before you paint. If you paint before the putty is completely dry, it won't form an effective seal and could discolor or leak over time.

Paint

You may be concerned about replacing a damaged piece of glass. The truth is, replacing a single pane glass doesn't need to be costly when you do it on your own. Even double-paned windows can be replaced for a fraction of what it will cost for a professional.

If you are working with large glass windows first, ensure that it is securely attached to the frame. This job is relatively easy and fast with the right tools and techniques.

Once you're ready to begin taking off the old window pane by removing the metal glazing points that are attached to it. These are essentially small metal triangles that act as "nails" that hold the window in place in the wood frame. They are buried beneath a layer of glazing putty, which transforms into a solid formed wedge that holds the window firmly in place and conceals the points.

After you have the old pane removed, clean up the surrounding frame and wood. Scrape off any paint that has been used, and sand the rabbet grooves where the glazing points were. They should be sanded to bare wood, so that you can paint them the same color as the rest of the frame. After sanding the wood then apply a layer of flax oil. This will help to prolong the life of the frame.

The next step is to determine the width of the window opening. It is necessary to take vertical and horizontal measurements of the entire opening, as well as the thickness of the old pane. Subtract 1/8 inch from each measurement to ensure you get the exact measurement for the new pane. This will also allow for expansion and contraction of the glass in times of seasonal change. Take these measurements to the hardware or home improvement store and have cut the glass 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.
