Window Repairs Can Save Homeowners Time and Money
Window repairs can save homeowners time and money. But, there are times when replacing old windows is more economical.
Projectiles and baseballs that are thrown often cause cracks or holes in window glass. These are usually simple fixes with the right tools.

If the frame of the window is beginning to decay it is recommended to replace the entire window.
Broken or cracked glass
A storm that is severe or a stray piece of debris from the lawnmower, or even your favorite vase that is set too hard could crack the glass in your windows. Fortunately just a little time and effort can stop these cracks from becoming worse and help you avoid the expense of replacing glass.
First, remove the broken glass. Wearing gloves, carefully rip away any molding, trim or glazing putty that keeps the glass in place. You may have to use a utility knife to cut off any glass pieces that are stuck in the frame.
After removing the glass clean the surface and any surrounding areas thoroughly. This will stop the glue used to put the glass back to its original position from leaking and causing further damage. It is also important to ensure that the glass you've purchased is a perfect fit. If the glass you're replacing is larger than the previous piece, you'll have to use a circular or mitersaw to trim it.
Once your surface has been cleaned, you can apply a glass adhesive made specifically for windows. Place the glass back inside your window sash. Be careful not to bend the glass or moving it during this step. This can cause cracks to grow deeper.
Finally, you can use a product like Loctite Super Glue Glass to fill the crack and seal it. It is designed to work on all kinds of glass including tinted ones. Just be aware that this type of repair will not fully cover the crack, therefore it's not a suitable solution for windows that are easily visible from the outside.
Another option is epoxy, which is more laborious to apply, but will provide the strongest seal and can make the cracked window virtually unnoticeable. Before applying epoxy, you'll need to clean your glass and the surrounding area thoroughly. You will also need be prepared for any sudden weather changes which could cause the cracks to expand. If you are not confident using these DIY techniques or if the cracked glass is particularly large or two-paned, it's recommended to consult a professional.
Sashes That Won't Open
A window that will not remain up is more than a nuisance; it could also be a risk. Double- and single-hung windows come with balancing mechanisms that prevent the sash from sliding up and down within the jambs. However, one or more of these mechanisms could become disconnected or damaged. Check the balance bar and pivot shoe to determine if either or both have been dislodged. You will have to replace the balance bar and pivot shoe if they have been dislodged.
The moisture inside the windows sash can trigger cycles of contraction or expansion. As time passes, this can loosen the joints of the frame and cause them to become stuck. It is possible to repair this issue without removing the window if you use a blade to break the joints of the frame apart. If your wood appears to be swelling, it's usually because of a lack of flashing on the exterior of your house which allows water to soak into the frame.
Another reason that is commonly cited for windows that don't open is a sash cord snapped. It is possible to reconnect the cord using pliers, and by sliding the sash into its normal position. If the cord is totally broken, you will have to replace it.
Paint can also cause windows to become bounded and be difficult to move. If the sash channel of double-hung windows has been closed with paint, you might be able to break the bond by using an utility knife and then slide it. If this doesn't work, you will need to take off the sash and then cut the seam between the sash and stop, parting strip or jamb on both sides of the window (Photo 1).
Sash shoes for single-hung windows may be made of plastic or metal. These shoes come with a U-shaped slot them that is locked when the shoe is in its usual position within the sash. To unlock the shoe, use an screwdriver to turn the slot until it faces the other way (Photo 2). Then, move the sash back and forth to see whether it is working correctly.
Rotting Wood
Wood rot isn't only unsightly and aesthetically pleasing, it is a serious threat to the structural integrity of the area of the home it's infiltrating.

The latter can happen when damp proofing isn't installed or damaged, or when internal materials like plaster and drywall are affected by leaky pipes, appliances or fixtures.
The first step to repair rot involves removing the old material. This is generally easy enough with a pry bar, although a combination of hammer and chisel may be necessary for the most difficult areas. After the decayed wood has been removed, the gap needs to be filled and sealed. There are a variety of wood fillers. The most suitable one will depend on the amount of work you want to do and the depth of the hole.
If the rot has spread out too far for a filler to work, you'll have to replace the damaged part. You can hire a professional to do this or do it yourself. This is a more difficult task that requires the expertise of a carpenter to complete. If you're not sure of your DIY ability here you should contact an expert.
