When It's Time to Repair Windows
It is important to be cautious when you are repairing windows. The first step is to wear a pair of safety goggles and gloves that are cut-resistant to prevent glass shards from slicing you while you work.
A quick fix for a window that is broken is to place a plastic cover over the crack. This will stop rain, snow and insects from entering the home.
Cracked Glass
Cracked window glass not only makes your home look less appealing but let drafts and other elements into the home. The cracks could be caused by an impact (like the impact of a soccer or baseball ball) or are a result of stress, such as an abrupt temperature change, it's important to get them fixed as soon as you can to avoid further damage and ensure your windows are working effectively.
If your window is damaged but not broken, an easy solution is to apply clear tape to it. It's a simple and inexpensive solution that can provide protection from dust, water bugs and other particles, as well as keeping out the elements.
However, if the crack is large or is getting worse, you should seek out an expert. A glazier who is experienced will be able to determine the cause of the crack and recommend a suitable repair method.
Impact cracks are the most common window breakage. They usually occur when a solid object strikes your window with enough force that it cracks. These cracks usually display an arc of lines and broken pieces. They could be dangerous in the event that they become loose. The crack could affect the gas in the panes of your double-pane window and reduce 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 can eventually grow into complete breaks.
A more serious, but doable crack is a pressure crack. It is typically a curvy line that extends across one or more sides of the window. It could be the result of high or low air pressure, which could cause expansion or contraction of the glass.
If you're willing to go further than nail polish and tape there are other products that can be used to repair cracks in your window glass. A product such as Glass Repair Film is a bit more costly, but it will provide a bit more protection and durability for your windows. If you'd rather DIY epoxy is an adhesive that can be used to repair cracks and prevent further damage. It will make your window appear like it never had any cracks at all.
Leaking Windows
If you see an area of dampness beneath your window, or notice that the wood around it is brittle or rotting, it could be time to start a windows repair. In excess moisture, it creates the perfect environment for mildew and mold, which can create a range of problems for your home. They can decrease the quality of indoor air, lead to sagging drywall, and can increase the severity of allergy symptoms. If not addressed they could cause structural damage to the house.
It is best to call an expert if the water is visible or leaking from outside. Leaking windows are one of the leading causes of structural and mold damage and should not be left untreated.
In many instances, caulking can be used to stop leaks. Before applying the new caulking, it's necessary to clean the area and take off any existing caulking.
You'll also have to inspect the weep holes in the frame to make sure they're not clogged with debris. They're designed to drain excess rainwater, but they can be clogged by insect corpses and other debris in time.
If windows have double panes, you'll also need to examine the seal between the glass and the metal frame. This will ensure a seal between the glass panes and make the windows more efficient. The seal could wear down with time and let water get into the home.
Another sign of leaks is the appearance of water-based stains on the ceiling and walls. window repair will turn discolored once it is saturated with water. There is also the possibility of peeling paint caused by the effects of the water weakening its adhesive properties and pulling away from the wall.
Faux Muntins & Mullions
In the past, muntins and mullions (or glazing bars in the UK) separated and held glass panes in classic multi-pane windows. After WWII larger expanses of glass that were tempered became available. They're used only as a decorative feature in a few older homes.
Often just a small or a single group of these wooden supports may be damaged by rain or wind and cause cracks to the window. The good thing is that you are able to repair the majority of these decaying or brittle parts.

First employ a rag to clean the affected areas. Use ammonia-based cleaning products that does not leave traces. Then, 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 then, use painter's masking tape to tape off the lower section of the window frame. Apply a thick layer of white paint to the areas that you lightly painted in the first pass. Allow the paint to fully dry before taking off the masking tape, and applying the second coat.
If you have a more severe problem like a crack that forms an hourglass shape in the middle of the window, then it's probably better to replace the sash. In these instances, you'll need to look for a replacement window that is compatible with the existing window in both the design and size.
To save money, you can also install an attached grid window. These windows are made of a glass pane with a series muntins, which are glued to the surface. This gives them a divided appearance. They are not as energy-efficient as traditional ones.
If you're looking for a simple method to upgrade your windows, you should consider installing a new drip cap to stop water from getting into the window frame. You can purchase a range of these aluminum drip caps at the majority of home centers for around $20. They are much easier to install than replacement window sashes, and will provide the same functionality as a genuine mullion or a muntin.
Broken Sashes & Frames
A damaged window sash is an obvious indication that it's time to get some help. If it's not checked the broken sash may cause wood rot, water leaks and more serious issues with the frame and sill. If you have a broken window sash, replace it as soon as you can to ensure that your window is properly sealed and functioning.
The issue is usually caused by worn-out or poorly installed cords. Luckily, replacing them is relatively simple and is possible in all double-hung windows. First, you'll need to remove the tabs of metal that hold the sash. Press upwards on the other side of the sash (it doesn't matter which side) and then pull towards the opposite side to take it off. You'll need to remove the strip that divides the sash from the other side so that you can get to the location where the sash cords are located.
After you've removed your sash, make sure you look at its metal tabs and compare them to the ones on your new sash. If they're different, it will be difficult to put the new sash in its correct slot and could impact how the sash operates. This can be easily fixed by putting the tabs in their proper places on the new window.
In addition to the sashes, you'll also have to examine the frame of your windows for problems or decay. It's a good idea to do this regularly as the wood shrinks and gets worn down over time, particularly after exposure to the elements. It is important to repair any visible damage as fast as possible to avoid a more serious 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 boiled Linseed oil. After the treatment has dried for two days, you are able to re-finish your frames using high-quality latex paint. A fresh coat of paint can also shield your window from the elements.
