How to replace window handles Window Panes

A damaged or cracked window can be a nuisance. This could be an opportunity to upgrade to energy-efficient windows or insulated ones to enjoy advantages like improved comfort, higher resale value and lower utility costs.

It's a task you can do yourself for a fraction of the cost of hiring a professional. You only need the right tools and a few hours of your time.

Glass

Replace your single-paned windows using tempered or insulation glass to improve energy efficiency, reduce noise, and maintain the historic integrity of your old home. A majority of homeowners with hand tools can repair the window pane. You'll also require an additional window pane, glazier's tips pliers, and latex glaze putty. If needed, you can use a heating gun to warm the old putty. Before starting, put on gloves and safety goggles as working with broken glass can cause injuries.

Remove any broken glass pieces remaining. It is recommended to use pliers for this however a flathead could work as well. After that, use a wood chisel or putty knife to remove the remaining old putty from around the frame and sash. Be careful and slow and be careful not to break the existing window sash. It is recommended to do this using a sturdy ladder rather than on the ground and to have someone standing below the sash in order to help hold it in place.

After you have removed all the old putty, you can prepare the window frame for the new pane. Find the width and sash the height of the sash opening, subtracting 1/8 inch from each measurement (to allow for seasonal expansion and contraction). These measurements can be sent to a home center or hardware store to get an item cut from glass stock to the proper size. You can also cut the glass by yourself if you have the appropriate tools.

After putting the new pane in place, 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 tight enough to create friction between the frame and sash, but they should also not be loose.

Before applying the putty, make sure to knead it until it is soft and free of lumps. Then you can roll it into pencil-sized strips. Apply the first strip to the corner of the frame. Work from one corner to another to ensure it's even and smooth.

Glazier's Points

The glazier's points are the small triangular pieces which help to secure glass into frames for windows without scratching or damaging the fragile surface. It's easy to understand how to use this secret tool and you can save money on the expense of a professional installation.

Once the old putty and the glazier's points have been removed and the frame is thoroughly cleaned with a utility knife to get rid of any remaining traces. Lightly sand the wood into the rabbet grooves to smooth rough areas. If you do sand the wood, be sure to protect it with painter's tape to avoid accidental damage.

Write down the dimensions of the frame. Take these dimensions to an 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 window in the frame and press it into place firmly by using your hands. Utilize the point of the chisel, or sash the edge of the putty blade to tap the glazier's points as shown in Figure 11. The glazier's point should be in line with the top edge of your pane and the shoulders should be just below that lip.

Apply a thin layer of glazing compound on the rabbet grooves and the edges of the glass. This will protect and seal the edges. Allow it to dry completely and cure.

When the glazing compound is dry and the glazing compound is dry, you can install the new window sash. First, you need to coat the wood with an even layer of linseed. This will prevent the new putty from drying out and cracking when it absorbs moisture. Apply the coat using a brush or the tip of your putty knife, and then use the chisel, or the back end from the putty knife to gently press the new sash and glazier's points into the grooves of the rabbet. Repeat this procedure every 10 inches along the frame's perimeter.

Putty

A baseball thrown at you or an unintentional rock, or falling branch could cause a window pane to break or crack. Fortunately, windows can be easily replaced by simply putting a brand new piece in place. The glass is held in place by a small metal clip, called a glazier's point and putty. This compound is also known as glazing compound. Before installing a new pane, first remove the old one and clean the area with a rag and a pull-type paint scraper or a wood chisel. Wear gloves and safety glasses when you work. If the window is attached to the frame, you'll need to use a heat gun to soften the adhesive prior to cutting it loose.

If you are planning to replace the original sash, gently 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. Once the sash is re-installed then, apply a new caulk made of silicone around the glass to ensure that it doesn't swell or fade in time.

Remove the glazing points from the rabbets and the grooves in the sash where the glass sits. If they're difficult to work out, try holding a hand tool like a heat gun to soften them first. If you're using a heating gun, make sure not to damage the sash or its railings by placing the tool too closely.

Prepare the bed for your new pane by removing the old putty and glazing points. Roll a rope of glazing compound between your hands, shaping it to be about 1/2-inch thick. Press it into the rabbets where the glass will be placed. The glass should rest against the putty on both sides. If necessary gently tap your glass into the rabbet with your thumb.

If the new pane has a crack, you can cover it with a solvent-based glue or silicone caulk before pressing it into the sash. If not, you'll have to putty over the crack to form an impervious seal 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 create a solid seal and could discolor or leak over time.

Paint

If you've experienced a broken window pane, then you may be worried about the cost of a new one. In reality, replacing a single pane of glass doesn't need to be costly even if you do it your own. In fact, even a double-pane window can be replaced at a fraction of the cost of a professional.

First, if you're working on a large window, make sure that it is securely attached to the frame. Using the proper tools and techniques you can accomplish this task fairly easily and quick.

When you're ready to start taking off the old window pane by removing the metal glazing points that are attached to it. These are tiny triangles of metal that function as "nails" to hold the window within the frame. They are placed under a bead or glazing glue that sets to form a solid wedge that holds the wood frame firmly in position and hides the points.

Once you have the old pane taken away Clean up the frame and wood. Scrape off any paint that has been used and sand the rabbet grooves in which the glazing points were. They should be sanded to bare wood, to allow you to paint them the same color as the rest of the frame. After sanding, apply a coat of flax oil to the wood that is not sanded down to prolong its life.

The next step is to determine the width of the window handle replacement's opening. It is necessary to measure 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 allow for seasonal changes in the glass. Take these measurements to your local hardware or home improvement store 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.
