Broken Panes

A broken window can cause numerous problems, as it can block air, light and even insects. While you could certainly hire a professional to replace the broken pane but you can also fix the problem yourself for a fraction of the cost.

To accomplish this, you will need to remove the old pane. Start by putting on safety glasses, gloves for work and a dust mask to protect yourself from lead shards and glass dust. Establish a stable work surface that is ventilated in an area. It is also recommended to place a drop cloth underneath the work area to catch any loose glass that is being removed. It is a good idea to have a HEPA vacuum nearby to clean dust, debris, and hazardous waste while you work.

Utilize a utility blade to scrape the old glazing putty off after the old window is removed. Be careful not to scratch the wood frame of the window. If the old putty is particularly stubborn, use a heat gun to soften it prior to scraping it away with a knife. Make sure you wear safety goggles when working with a heating gun, and be cautious to avoid getting hot wood or glass shards in your eyes.

Next, prepare the frame to accept the new pane. Measure the opening, and subtract 1/16 inch in both directions to account for expansion and contraction of the wood. Your local hardware store will cut an inch of double strength glass to precisely fit the opening. Before you install the new glass dry-fit it for an ideal fit.

After you have the glass in place, apply a small bead of latex caulk around edge of the opening to provide an excellent weather seal. Then, install the glazing points to keep the new pane in the proper position. Typically, you will need two points on each side for typical sizes of window glass.

When the new glaze compound dries you can then paint it to match the rest. If you're worried about the possibility of cracks, you can apply a strong strip of masking tape in order to keep superficial cracks from getting worse.

Frames that are damaged

You should inspect the frame first. If there are cracks, corrosion, or rust or the frame is broken into two pieces, you'll have to take it in for professional repair. Metal frames are not able to be glued and any attempts to weld or solder them will result in permanent damage.

If the frame isn't too damaged, you can make use of a small brush and some conservation detergent or water to clean the frame carefully. This will eliminate any dust, grease or dirt that may have accumulated over time. Cleaning old frames with intricate carvings or gesso could reveal the original finish beneath the dust.

If the frame is damaged, you'll need a pair of needle-nosed pliers and sandpaper as well an adjustable clamp. Take off the back, the photo and the glass of the frame. Take care to break the frame at the corners, where you'll see the nails or brads. Unlock the joints and remove any glue that is old. Apply new glue.

Loose Compound

The glazing compound that keeps glass window panes within their wooden frames is a vital part of any historic building's energy efficiency. It seals the wood, bonds the glass glazier to the frame and sheds moisture to prevent water damage as time passes. This compound can break or have gaps that let air in the frame, reducing insulation values and increasing utility bills. Keep up with the repair work on your double-glazed window to ensure they are operating smoothly.

The weatherstripping can be worn out or loose if you notice drafts around your window frames. This seal can reduce energy costs and increase comfort. If you hear loud noises outside, such as traffic or machinery, it could mean that the glass tape is worn out.

Remove the old tape from the edge of the frame and scrub the area thoroughly. Apply a new piece of tape to the frame's edge and press firmly. This tape is available at any hardware shop and is an inexpensive way to improve the performance of your double-glazed window.

While standard super glues are effective for bonding metal, wood and other common materials, they're not ideal for use on glass-based surfaces. Choose a glass-based glue, such as Loctite Extreme Glue Gel. This kind of glue is made to resist sunlight and moisture, which makes it a better option for repairing double-glazed windows.

You'll need to use a degreaser to clean the surface of your window frame and sash before you begin to repair it. This will ensure that the new adhesive adheres correctly. Prepare the area that will be coated by using an oil-based primer. Make sure to prime the entire surface including the back of the sash, where it rests in the frame.

Foggy windows are often caused by the simple accumulation of moisture which is why the first step is to eliminate as much moisture as possible. You can do this by using a defogging product or shaving cream. If none of these solutions work you need to call in an expert.

Double pane windows are able work because of the space between them. This space is usually filled with argon or krypton, which are non-toxic gases that are more dense than air and could slow heat transfer even further. If the gas has leaked out, your windows aren't insulated properly. Replace your windows with IGUs to fix the fogging and restore your home's efficiency.

Some glass shops offer to replace the insulation unit (IGU) only, without replacing the entire frame or the sash. This is a more affordable option and is just as effective in fixing your windows.
