Glass

If your single-pane windows are old, deteriorating or broken replacing them with modern glass that is tempered or insulated will improve energy efficiency and reduce noise while maintaining the historical integrity of older homes. The procedure of replacing a window pane is relatively simple and can be done by most homeowners who possess basic hand tools. Alongside a replacement pane, the following components are required such as latex glazing putty; glazier's points; pliers; and the use of a heat gun to warm the old putty if required. Wear safety goggles and gloves prior to beginning. Working with broken glass can cause serious injuries.

Begin by removing any broken pieces of glass. This is best accomplished with pliers, however, a flathead screwdriver may work in the pinch. After that, use a wood chisel or putty knife to remove the remaining old putty from around the frame and the sash. Take your time and work slowly, taking care not to break the existing window sash. It is best to do this on a stable ladder instead of the ground, and to have someone standing below the sash in order to help hold it in place.

Make sure the window frame is ready to receive the new pane once you have removed the old putty. To allow for seasonal expansion or contraction, subtract 1/8 inch each from the measurements of the width and height. These measurements can be taken to a hardware or home center store to have a piece cut of glass that is in stock to the correct size. You can also cut the glass yourself if have the tools you need.

After installing the new glass Apply some caulking around the edge. This will make the glass weatherproof. Then, you can install a glazier's pointing on each side of the frame to secure the pane in the right place. The points should not be so tight that they create friction between the sash and frame however they should not be too loose.

Before putting the putty on, make sure to knead it until it is soft and free of 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 another and ensure that it is even and smooth.

Glazier's Points

The glazier's points are tiny triangular pieces of metal which help to secure the glass to the frame without damaging the delicate surface. Knowing how to use these hidden tiny pieces of help is simple and can save you money on a professional installation or the cost of purchasing new glass.

Once the old putty and glazier's points are removed Clean the frame thoroughly with a knife to get rid of any remaining traces. Lightly sand the wood in the rabbet grooves to smooth out rough areas. If you decide to sand wood, protect it with painter’s tape to avoid accidental damage.

Note down the dimensions of the frame. Bring these measurements to a hardware store or home center and request that the new pane cut smaller than the frame's opening. This will ensure a snug fit, and allow for expansion and contraction.

Place the new window in the frame and press it in place by using your hands. Then, use the tip of your chisel or back end of the putty knife to tap in the glazier's points, as illustrated in Figure 11. The glazier's point should be in line with the top edge of your pane, and the raised shoulders should be just beneath that lip.

Apply a thin bead of glazing compound over the edges of the glass that has been made and into the rabbet grooves, to seal and protect them. Let it dry completely and cure.

After the glazing compound dries 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 from sucking up moisture and drying out and cracking over time. Apply the coat using a brush or the edge of your putty knife, then employ the chisel or back end of the putty knife to gently hammer the new sash and glazier's tips into the rabbet grooves. Repeat this procedure every 10 inches along the perimeter of the frame.

Putty

A baseball hit or a rock thrown in error or a branch falling can result in a cracked or cracked window. Luckily, most windows can be replaced by simply placing a new piece of glass in its place. The glass is held into position by a small metal clip, also known as the glazier's point, and putty. This compound is also known as glazing compound. Before installing a new pane, first get rid of the old one and clean the area with a rag and an abrasive scraper that is a pull type or a wood chisel. Wear gloves and safety glasses while you do this work. If the window is glued to the frame, you'll need employ a heat gun in order to soften the adhesive before prying it free.

If you are planning to replace the original sash, gently remove any molding pieces that hold the old pane in place. Sand the sash until it's flat and ready for new caulk. Once the sash is installed, you can apply a silicone caulk on the glass. This will ensure that it won't be leaking or fade over time.

Remove the glazing points from the rabbets. These are the grooves on the sash, which is where the glass is located. If they're hard to cut, place a hand Replace window pane tool such as a heating gun over them to allow them to soften before. When using a heat tool, make sure to avoid damaging the sash's railings and sash.

Prepare the bed for your new pane after you have removed the old glaze points and putty. Roll a rope of glazing compound between your hands, shaping it to be about 1/2-inch thick. Place it into the rabbets, where the glass will be placed. The glass should rest against the putty on both sides. If necessary, lightly tap your glass into the rabbet using your thumb.

If the new pane has a crack you can fill it with a solvent-based glass glue or silicone caulk prior to pressing it into the sash. If the crack is not sealed, you will require putty to keep water out. After the putty has dried clean the oily film off of the glass and allow it to dry completely before painting. Paint after the putty has completely dried. It will not form a good seal and could discolor or leak over time.

Paint

You might be worried about replacing a damaged piece of glass. However, replacing a single glass pane doesn't need to cost a fortune if you do it yourself. Even a double-paned window could be replaced for a fraction of what it would cost an expert.

First, if you are working on a large-sized window, make sure it is securely fixed to the frame. By using the correct tools and techniques to make this task relatively easy and quick.

When you are ready to begin taking down the old window pane. Remove the metal glazing points attached to it. They are basically tiny metal triangles that act as "nails" that keep the window in place in the wood frame. They are buried beneath a glaze putty or bead that sets to form a solid wedge that holds the wood frame firmly in position and hides the points.

After you have the old pane removed Clean up the frame and wood. Scrape off any old paint and sand replace window pane the rabbet grooves where the glazing points were. They should be sanded to bare wood to allow you to paint them the same color as the rest the frame. After sanding the wood, apply a layer of flax oil. This will help extend its life.

The next step is to measure the dimensions of the window replacement companies's opening. You will need to measure the horizontal and vertical dimensions of the entire opening, as well as the thickness. To get the exact size of the new pane subtract 1/8 inch from both measurements. This will also allow for expansion and contraction of the glass during seasonal change. 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.
