Glass

Replace your single-paned windows with tempered or insulated glass to increase energy efficiency, reduce noise, and protect the historic integrity of your home's older. The procedure of replacing windows is easy and can be accomplished by most homeowners who possess basic hand tools. In addition to a replacement pane, the following tools are required such as latex glazing putty; pliers, glazier's points and the use of a heat gun to warm the old putty if required. Wear safety glasses and gloves prior to beginning. Working with broken glass could cause serious injuries.

Begin by removing any broken pieces of glass. It is best to use pliers for this however, a flathead may be used as well. Make use of a wood chisel or putty knives to remove any old putty remaining around the frame and the window sash. Be careful not to break the window sash. Take your time and work slowly. This is best done on a ladder, not the ground. Also, have someone lower to ensure it is held steady.

Once you have removed all the old putty, you can prepare the window frame to fit the new pane. Measure the width and height of the opening for the sash by subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Bring these measurements to the nearest hardware store or home center, and get a piece of stock glass cut to size. You can cut the glass yourself if you possess the appropriate tools.

After installing the new glass, apply some caulking on the edges. This will make the glass weatherproof. Install a glazier's pointing on both sides of the frame. This will help secure the pane. The points should not be so tight as to cause friction between the sash and the frame however they shouldn't be too loose.

Before applying the putty, make sure to knead it until it is smooth and free of lumps. Make it into pencil-sized strips. The first strip should be glued to the corner of the frame. Work from corner to corner to ensure it's even and smooth.

Glazier's Points

The glazier's points are tiny triangular metal pieces which help to secure the glass to the frame without causing damage to the delicate surface. Knowing how to use these hidden little helpers is easy and could save you money on a professional installation or the cost of new glass.

After taking off the old putty, replace window pane glazier points, and any other leftovers, clean the frame thoroughly with an utility knife. Lightly sand the wood into the rabbet grooves if needed to smooth rough areas. If you sand wood protect it with painter’s tape to prevent accidental damage.

Measure the empty frame's dimensions and note down precise measurements. Bring these measurements to an 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 into place firmly by using your hands. Then, use the tip of your chisel or the back end of the putty knife to make a tap on the glazier's points as shown in Figure 11. When you're done, they should be in line with the top edge of the pane, and the shoulders that are raised of the points should be below the rabbet's lip. groove.

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

When the glazing compound is dry and the glazing compound is dry, you can install the new window sash. The first step is to coat the wood with a heavy coat of linseed oil. This will keep the new putty from sucking up the moisture and drying out and cracking with time. Apply the coat using a brush or the edge of your putty knife, then use the chisel or the back end of the knife to gently hammer the new sash and glazier's points into the grooves of the rabbet. Repeat this process every 10 inches around the frame's perimeter.

Putty

A baseball hit or a rock thrown by error or a branch falling can result in a cracked or cracked window pane. Most windows can be repaired easily by simply putting in a fresh piece. The glass is held in place by a small metal clip, referred to as the glazier's point, and putty. This compound is also called glazing compound. Remove the old pane and clean the area with a rag, a pull-type scraper or wood chisel. Wear gloves and safety glasses while doing this work. If the window is attached to the frame, you'll need to make use of a heat gun to soften the adhesive prior to cutting it loose.

If you're planning to install the original sash in the future, take care to remove any molding pieces that are used to secure the old pane. Sand the sash until it's flat and ready to receive new caulk. Once the sash is installed and sanded, apply a fresh caulk made of silicone around the glass to ensure it doesn't swell or fade over time.

Remove the glazing points from the rabbets, the grooves in the sash that the glass sits. If they're difficult to cut out, you can try holding the hand tool, replace window pane such as a heat gun to soften them before you do. If you're using a heat gun, make sure not to scratch the railings or sash by holding the tool too tightly.

Create a bed for your new pane after you have removed the old glaze and putty. Roll a rope of glazing compound between your hands, forming it to be about 1/2-inch thick. Place it into the rabbets where the glass will be put. It is essential that the glass rests against the putty on both sides If you have to do so, gently tap the glass into the rabbet with your thumb.

If the new pane has cracked, you can apply a silicone caulk or glass glue based on solvents to fill in the crack before pressing it into the sash. If the crack isn't sealed, you will require putty to keep water from getting in. After the putty is dry then clean the oily film off the glass using the help of a rag. Allow it to dry completely before painting. If you paint before the putty is fully dry, it won't create an effective seal and could discolor or leak over time.

Paint

You might be worried about replacing a broken pane of glass. But the truth is that replacing one glass pane does not have to break the bank if you do it yourself. In fact even windows with double panes can be replaced at only a fraction of the cost of an expert.

If you're working with large glass windows first, ensure that it is securely fixed to the frame. Using the proper tools and techniques you can complete this task easily and quick.

When you're ready to start with the removal of the old window by removing the glazing points of metal that are attached to it. These are small metal triangles which act as "nails" that hold the window screen replacement in place. They are submerged beneath a layer of glazing putty, which is then cured to form a solid, molded wedge which holds the window in place and conceals the points.

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

Next, measure the width of the window opening. You'll need to determine the vertical and horizontal dimensions of the entire opening, as well as the thickness. To determine the exact dimensions 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.
