How to Do Window Pane Replacement

It is important to replace a broken or cracked window pane as soon as possible. It could lead to a decline in energy efficiency or cause moisture to build up between the two panes.

Replacing a window's pane is cheaper than replacing an entire window and is easily done by the average homeowner. To replace a pane you will need to remove the old window and clean the frame and apply new putty.

Remove the old Pane

The first step to replace windows is to remove the old pane. It is crucial to use safety equipment such as gloves and masks for face. If you are able it is recommended to work on the floor and use a ladder which can be secured safely to prevent falling. Once the old pane is removed, you can begin working on the frame of the window. This is the ideal time to clean the area and lightly sand it. After this, apply a coat of linseed oil on the frame of the wood to help the glazing compound to remain flexible.

When you're ready to start the project, ensure that your workspace is free of any debris and you have the tools you require. Use a utility blade to scrape off any old glue on the glass and in the window frame. This may take some time and effort, but it is vital to have a top-quality product.

After you have removed the old putty, you will have an opening that is clear to accommodate your new window. To ensure that the new window pane will fit, measure the opening and subtract 1/8" from the width and length. You can also take a portion of the old pane to a hardware store to make sure it matches the style of glass and thickness.

Window panes aren't only there to look pretty - they can actually help make your home more efficient in terms of energy efficiency by decreasing heat loss, glare, and noise. The good news is that replacing a single window pane is a relatively easy task you can do yourself.

After replacing the damaged window, you'll need caulk to seal the edge of the window to keep it in position. This will not just give your window a beautiful look, but it will also make it more energy efficient and waterproof. Installing a window film can save you money on your energy bills by cutting down on the amount of heat lost through your windows.

Remove the Putty

The glazing putty that is used to hold panes of glass in frames can be extremely difficult to remove. It gets harder as it dries and makes it difficult to remove without damaging the glass. To avoid this, it is best to take out the old putty prior installing the new one. It isn't an straightforward task but it can be done with a bit of patience and effort. Wearing leather gloves and eye protection is a must when working around glass. It could be hazardous.

Take out any nails or spriggs securing the window in position before you begin to remove the putty. These nails were used to keep the window in place prior to when double glazing or upvc was available. They are usually located in the corners of the frame and can be removed using a screwdriver if they are exposed or cut off using a hacksaw. If they are hidden, you will require a small chisel (or putty chisel) to remove the frame.

Once the nail is removed you'll need to use mineral spirits to remove any remaining pieces of old putty. The product is available at most hardware stores and should be used in a ventilated area. Apply the oil in short bursts because overheating the paint or wood can make it to crack or explode.

A heat gun can also be utilized to soften the putty. This will work better on putty that has been painted over or is hardened and can be extremely efficient. Make sure to keep moving when using the heat gun since being stationary for too long can burn the wood and cause cracked glass.

You can also use a steel wool to get rid of the putty, however this method is not as effective and can be quite messy. This method should be used only as a last resort, and is not recommended for homes with children.

Remove the Glazing Points of Metal

A hurled baseball or errant tree branch can be a disaster on a window. While many people think that the broken window will require a complete windowpane replacement of the frame and the sash, it is possible to fix the view and lower the cost of energy by replacing only the glass.

The first step of a window glass replacement is to remove the metal glazing points that hold the old glass in place. Utilizing a putty knife scrape away as much of the softened glaze as possible to expose the glass points. There should be four points that are on either side of the frame. Once you have a clear view of the metal using needle-nose pliers, grip each one and pull it out straight. Do not pull too difficult. If the point is stubborn, or breaks, it could damage the frame.

Once the putty and metal glazing points have been removed, it is now time to prepare the frame to accommodate the new glass. Make sure the grooves are free of cracks and dents. Use a heat gun to assist in this process. But be cautious and utilize low temperatures to avoid the wood from warping or getting damaged.

If the glass is double-paned you can bring a small piece of the previous pane to ensure that the new one fits correctly. Spread a thin layer silicone sealant onto the inner frame rabbet and press the new glass into it. Trim any excess sealant using a razor blade, and then paint the exterior to finish.

If you only have one pane of glass to install then skip this step and go directly to the next. If the new glass thickness differs from the original, you will require a new piece of glass in the appropriate size at your local glass cutter. Before installing the new pane, place a glazier's push point in each corner of the frame rabbet (two on each side for a small window, and more for larger windows). This will provide additional support to the pane and to prevent it from being snagged in time.

Installing the New Pane

Window panes don't only provide aesthetics, they also improve efficiency in energy use, shield the house from rain and insects, as well as improve security. When they are damaged or broken, it is important to replace them immediately. A lot of homeowners aren't aware of the best way to replace a window. Luckily, it's actually pretty simple to repair a window. It's simple to replace a window pane with just a few items and a few steps.

Start by removing the old window, taking care not to cut yourself while you work. Be sure to have a towel handy to wipe off any remaining glass. Save the shards in case you require a new window. After removing the old glass take a measurement of the opening of the frame using the help of a tape. Note down the measurements and subtract 1/8 inch from each side to arrive at the new glass size. This will guarantee a tight fitting glass and allow for natural expansion and contraction. Bring the measurements to your local hardware or home improvement store and let them cut a piece glass for you. Bring a shard of glass from the old window that matches the thickness and the type.

Apply a small amount of latex caulk around the edges of the glass after it has been placed. This will form an airtight seal. Then, put glazier's points into the holes of the frame of wood close to the edge of the glass. You'll need two points per side to make a total eight.

You can also put in any wood molding that is left around the frame's edges. Make sure to wash the molding and putty well before reinstalling them so they don't interfere with your new pane.

It is tempting to put off replacing a broken pane of glass, however this could cause further damage to the glass and surrounding sash. It is also possible to replace the entire window in the future. Replacing a broken window pane is a relatively simple process that can be completed by any homeowner who has basic tools.
