How to Replace Window Panes

A cracked window pane can cause a lot of trouble. It could also be an opportunity to upgrade your glass to energy-efficient or insulated windows, and enjoy benefits such as improved comfort, increased resale value and reduced utility costs.

It's a task you can do yourself for less than the cost of hiring a professional. It requires the right tools and an hour or two of your time.

Glass

If your single pane windows are old damaged, cracked or deteriorating replacing them with more modern insulated or tempered glass can increase energy efficiency and reduce noise while maintaining the historical integrity of older homes. The majority of homeowners with basic hand tools can repair windows with ease. You'll also require a replacement window pane, glazier's tips, pliers, and latex glaze putty. If you need to you may use a heatgun to warm the old putty. Before starting, put on protective gloves and goggles since working with broken glass could cause injuries.

Take out any broken glass pieces remaining. This is best done using pliers, though using a flathead screwdriver may be effective in the pinch. Utilize a wood chisel or putty knives, to take away any old putty remaining around the frame and window sash. Work slowly and carefully, taking care not to damage the old window sash. This can be done best on an elevated ladder, not on the ground. Also, have someone on the ground to hold it steady.

Once you have removed all of the old putty, prepare the window frame for the new pane. Find the width and repairmywindowsanddoors the height of the opening for the sash and subtract 1/8 inch from each measurement (to allow for seasonal expansion and contraction). Take these measurements to an 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 putting in the new glass Apply caulking on the edges. This will make the glass weatherproof. Install a glazier's point on both sides of the frame. This will help secure the pane. The points should not be so tight that they create friction between the frame and sash However, they should not be loose.

Before applying the putty, knead it thoroughly until it is smooth and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be placed in the corner of the frame, working from one corner to the next to ensure it is smooth and even.

Glazier's Points

The glazier's facets are small triangular pieces of metal that help secure glass into the frame of a window handles replacement without scratching or damaging the fragile surface. It's easy to understand how to use this secret tool, and you'll save money on the expense of an expert installation.

After getting rid of the old putty glazier points and any residue Clean the frame thoroughly using a utility knife. If necessary it is necessary to lightly sand the wood in the grooves of the rabbet to smooth out rough spots. If you decide to sand wood, protect it with painter's tape to prevent accidental damage.

Take the dimensions of the frame and note down precise measurements. Take these dimensions to a hardware store or a home center, and have the new pane cut slightly smaller than the frame's opening. This will ensure a tight fit, and allow for expansion and contraction.

Place the new pane into the frame and press it into the frame with your hand. Then use the point of your chisel or the back of the putty knife to make a tap on the glazier's points as illustrated in Figure 11. After you're done, the points should be level with the top edge of the pane and the shoulders that are raised of the points should be below the rabbet's rim groove.

Apply a thin layer 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 and cure completely.

When the glazing compound is dry it's time to put in the new window sash. First, coat the wood with a thick coat of Linseed oil. This will stop the new putty from taking up moisture and drying out and cracking over time. Apply this coat with a brush or the edge of your putty knife, then employ the chisel or back end from the putty knife to gently hammer the new sash and glazier's point into the rabbet grooves. Repeat this procedure every 10 inches around the perimeter of the frame.

Putty

A hurled baseball or a rock that is errant or a fallen branch can cause a window to crack or break. Fortunately, the majority of windows can be easily replaced by simply placing a new piece in the proper place. The glass is held into the position with a tiny metal clip, referred to as a glazier’s point and putty. This compound is also called glazing compound. Before installing a replacement pane, first remove the old one and clean up the area with an abrasive and an abrasive scraper that is a pull type or the wood chisel. Wear safety glasses and Repairmywindowsanddoors gloves when you work. You'll require a heat gun when the window is fixed into the frame.

If you're planning to reinstall your original sash, remove the molding that supports the old pane. Sand the sash until it's flat and ready for new caulk. After the sash has been put back in place 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 from the rabbets and the grooves in the sash that the glass is. If they're hard to chisel out, try placing an instrument like a heat gun to soften them before you do. When using a heating tool, make sure to not scratch the sash or its railings.

Make a bed for your new pane after removing the old glaze and putty. Roll a rope of glazing compound between your fingers and then make it about 1/2 inch thick. Press it into the rabbets, where the glass will be put. It is crucial that the glass is positioned against the putty on both sides If you have to, lightly tap the glass into the rabbet with your thumb.

If the new pane has a crack then you can seal it with a solvent-based glass glue or silicone caulk prior repairmywindowsanddoors pressing it into the sash. Otherwise, you'll need to putty over the crack to create a tight seal and keep water out. After the putty has dried, wipe the oily film from the glass and allow it to dry completely before you paint. Paint before the putty is completely dry. It won't form a good seal and could be leaking or discoloring over time.

Paint

If you've experienced a broken window pane, you may be concerned about the expense of a new one. But the truth is that replacing a single glass pane doesn't have to break the bank when you do it yourself. Even a double-paned window can be replaced for a fraction of the price it will cost a professional.

If you're working with a large glass window first ensure it is securely fixed to the frame. This is relatively easy and quick with the right tools and techniques.

When you're ready to start, begin by removing the old window by prying out the glazing points made of metal that are attached to it. These are tiny triangles of metal that act as "nails" to hold the window in the frame. They are submerged beneath a glaze putty or bead which hardens into an unbreakable wedge which holds the wood frame securely in place and conceals the edges.

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

The next step is to determine the size of the window's opening. You will need to measure the vertical and horizontal dimensions of the entire opening, as well as the thickness. To determine 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 in times of seasonal change. Bring 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.
