When It's Time to Repair Windows
If your windows are in need of repair, it's essential to work carefully. Wear safety goggles and gloves to protect yourself from glass fragments.
A quick solution to a damaged window is to put an aluminum cover over the crack. This will prevent insects, snow, and rain from entering the home.
Glass that has cracked
Cracked glass can make your home appear less appealing and allow drafts to enter. Whether the cracks were caused by an collision (like the impact of a soccer or baseball ball) or are the result of stress, like a sudden change in temperature or a sudden temperature change, it's crucial to get them fixed as soon as you can to avoid further damage and ensure your windows are operating properly.
Use clear tape to cover your cracked window if it's not broken. This is a cheap and simple solution to shield your window from water, dust bugs and other sand. It also keeps out the weather.
If the crack is getting larger or has become extensive, it is best to speak with a professional. An experienced glazier will be able to determine the cause of the crack and recommend an appropriate repair procedure.
Impact cracks are the most common window breakage. They usually occur when a hard object is thrown at your window with enough force that it breaks. The cracks are usually followed by a starburst pattern of lines and shattered pieces that can be dangerous if they come loose. The crack could compromise the gas in the panes of your double-pane windows and lower its energy efficiency.
Stress cracks are another type of crack that develops because of extreme temperature changes and other environmental factors. These cracks usually begin near the edges of your window, and eventually can develop into full-blown breaks.
A pressure crack is a more serious crack but it is still able to be repaired. It is typically a curvy line that extends across one or more sides of your window. It could be the result of low or high air pressure, which can cause contraction or expansion of the glass.
If you're ready to take a step beyond nail polish and tape there are a few other products that can be used to repair cracks in your window glass. A product like Glass Repair Film is a bit more expensive but will offer a bit more protection and longevity for your windows. If you'd rather take the DIY option epoxy is a durable adhesive that can fill in cracks to help prevent further damage and make your window appear like it has never had cracks in the first place!
Leaking Windows
If you notice an area of dampness beneath your window, or notice that the wood around it is soft or rotting, it may be time to start a windows repair project. Mildew and mold thrive in excessive moisture and can cause a number of problems within your home. They can reduce the quality of air inside, contribute to sagging drywall and even worsen symptoms of allergies. If not addressed they could cause structural damage to the home.
It is best to call a professional if the water is visible or comes from the outside. Do not ignore windows that are leaking. They're a major cause of mold and structural damage.
In many cases, a simple layer of caulking is all you need to stop leaks. You'll need to thoroughly clean the area, however, and then take off any caulking that is old before applying the new layer.
It is also important to examine the weep holes on the frame to ensure they're not blocked by debris. They're designed to drain excess rainwater, but they can get blocked by insect carcasses and other debris as time passes.
If windows have double panes it is also necessary to examine the seal between the glass and the metal frame. This will ensure a seal between the glass panes and help make windows more efficient. Over time the seal will get worn out and let water into your home.
Another sign of leaks is the presence of water-based stains on the ceiling and walls. The drywall becomes discolored when it is soaked with water. Peeling paint is another indicator of water altering the adhesive properties of the paint and pulling it from the wall.
Faux Muntins & Mullions

In the past, muntins (or glazing bars, as they are referred to in the UK), separated and were used to hold the panes of multi-paned windows. After WWII, larger expanses glass that were tempered became available. Nowadays, they're used as a decorative feature in some older homes.
Rain or wind can cause damage to the support of a single piece or small group, leaving cracks in the window. You can repair the majority of these brittle and decaying elements.
First, clean the affected areas with a rag and an ammonia-based cleaner that doesn't leave a traces. Remove any loose or rotting parts and use an exacta-knife cut the intersections between the vertical and horizontal painted window muntins. After trimming the intersections using painter's masking tape, you can use the tape to seal off the lower section of the window frame. Now, you're able to apply a heavy coat of white paint, paying special attention to the areas that were lightly coated in the first go. Allow the paint to fully dry prior to removing the masking tape and applying the second coat.
If you're experiencing an issue that is more serious like a crack that forms an hourglass shape in center of the window, then it's probably recommended to replace the sash. In these cases, it's important to find an alternative window that is in line with the style and size of the current one.
For a less expensive alternative, you can also install an attached grid window. These windows feature a complete pane of glass with a series of muntins glued to the surface creating a divided appearance. They're not as energy-efficient as traditional windows, but they are.
Installing a drip cap can stop water from entering the window frame. Most home centers sell these aluminum drip cap options for about $20. They're much easier to install than an alternative window sash, and they'll provide you with the same function as an authentic mullion or muntin.
Broken Sashes & Frames
A broken window sash should be a signal that you need to seek help. A sash that is broken not addressed, can lead to water leaks, wood decay and other serious problems to the frame and sill. If you've damaged your sash, replace it right away to ensure that the window is properly sealed.
Most of the time, the issue is caused by worn out or improperly installed the sash cords. Luckily, replacing these is quite simple and can be accomplished in all double-hung windows. First, you'll need to remove the tabs of metal that hold the sash. Then, push up on window repairs near me of the sash (it doesn't matter which side) and then pull toward the opposite side in order to take it off. You'll need to remove the parting strip that divides the sash from the other side so that you can get to the location where the sash cords are located.
It is important to examine the metal tabs of the old sash with the new one. If they're different it's difficult to put the new one in its slot and affect how the sash operates. Luckily, this is easily fixed by placing tabs in the correct locations on your new window.
You'll have to examine your window frame, too for any damage or decay. It's a good idea to do regularly, as wood will shrink and wear down over time. If you find any visible damage, it must be addressed as soon as you can, to avoid the development of a larger issue.
If your window frames are in bad condition, you'll need to treat them using a homemade preserver made by mixing half mineral spirits with half boiling Linseed oil. After the treatment has dried, you are able to finish your frames with high-quality latex paint. A new coat of paint can protect your window from the elements, too.
