When It's Time to Repair Windows
It's important to be careful when fixing your windows. Wear safety goggles and gloves to protect yourself from glass shattering.
Covering the crack with a plastic sheet over the crack is an easy fix for a damaged window. This will prevent rain, snow and insects from entering your home.
Glass that has cracked
Glass that is cracked can make your home appear less appealing and allow drafts to pass through. Whether the cracks were caused by an impact (like the impact of a soccer or baseball ball) or are the result of stress, like an abrupt temperature change, it's important to get them repaired as soon as you can to avoid further damage and keep your windows working correctly.
Use clear tape to cover your damaged window if it's not damaged. This is a quick, low-cost solution to protect your window from dust, water bugs and other debris. It also shields your windows from the elements.
If the crack is severe or is getting worse, it's best to consult a professional. A professional glazier will determine the cause of the crack and recommend the best repair method.
Impact cracks are the most frequent kind of window break, typically caused by a sharp object striking your window with enough force to fracture it. The cracks are usually with a starburst-like pattern of lines and broken pieces that can be risky if they break loose. The crack could compromise the gas that is between the panes of your double-pane windows and reduce its energy efficiency.
Stress cracks are another type of crack that develops over time due to extreme temperature fluctuations and other environmental factors. The cracks start around the edges of your window, and eventually can develop into complete breaks.
A pressure crack is a more severe crack, but it can still be repaired. It's usually a curvy line that runs across one or more sides of your window. It could be a result of high or low air pressure that can lead to expansion or contraction of the glass.
There are window repairs that can be used to repair cracks in window glass if you're willing go beyond nail varnish and tape. A product such as Glass Repair Film is a little more expensive, but will provide more protection and longevity for your windows. If you prefer to do it yourself 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 any point.
Leaking Windows
If you notice an area of dampness under your window, or notice that the wood around it is soft or rotting, it may be time to consider a window repair project. Mildew and mold thrive in excess moisture, which can lead to numerous issues in your home. They can lead to indoor air pollution, sagging walls, and can even increase the severity of allergies. If not addressed they can cause structural damage to the home.
It is best to call an expert if the water is visible or leaking from the outside. Leaking windows are one of the most common causes of structural damage and mold, so don't leave them untreated.
In many cases the use of caulking is to stop leaks. Before you apply the new caulking, you'll have clean the area and get rid of any caulking that is in place.
It is also important to examine the weep holes on the frame to make sure they're not blocked with debris. They are designed to drain off excess rainwater, but they could become clogged with insect corpses and other debris as time passes.
Examine the seal between the double-paned window and the frame. This helps to keep a gas barrier between the panes, which makes the windows more energy efficient. Over time the seal may get worn out and let water into your home.
Water stains on ceiling and walls are another indication of leaks. The drywall turns discolored when it is saturated with water. Peeling paint is another indicator of water altering the adhesive properties of the paint, and pulling it away from the wall.
Faux Muntins & Mullions
In the past muntins (or glazing bars, as they are referred to in the UK), separated and held the panes of classic multi-paned windows. After WWII, larger expanses glass that were tempered became available. Nowadays, they're used as a decorative element in some older homes.
The effects of rain or wind can harm one support or a small group, leaving cracks in the window. Repairs can be made to the majority of these brittle or decaying parts.
First take a rag and clean the affected areas. Make use of a cleaner based on ammonia that will not leave residue. Get rid of any rotting or loose pieces and trim the intersections of the horizontal and vertical window muntins using an exact knife. After trimming the intersections then, use painter's masking tape to tape off the lower part of the window frame. Now, you can apply a thick coat of white paint, paying particular attention to the areas which were lightly coated on the first go. Allow the paint to dry completely before removing the tape and applying a second coat.
If the issue is more severe such as an hourglass-shaped crack in the middle of the window, it's better to replace the sash. In these situations it's crucial to find the right replacement window that matches both the style and size of the current one.
If you want to save money you can install an attached grid window. These windows have a full pane of glass that is topped with a series of muntins glued to the surface which gives them a split appearance. They are not as efficient in terms of energy efficiency as traditional windows.
Installing a drip cap can stop water from entering the window frame. The majority of home centers sell drip caps in aluminum for around $20. They're a lot easier to install than a replacement window sash and come with the same functions as a real muntin or mullion.
Broken Sashes & Frames
A damaged window sash must be a sign that you need to seek 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 sill, you must replace it as soon as you can to ensure that your window is properly sealed and operating.
The problem is often caused by damaged or improperly installed cords. It's simple to replace these cords on the majority of double-hung window models. First, you'll need to remove tabs made of metal that hold the sash. To do this, you need to push up on one side (it doesn't matter which) of the sash and then pull it towards the other side to remove it from the window frame. You'll need to remove the strip that divides the sash from the other so you can access the location where the sash cords are located.
It's important that you compare the metal tabs of the old sash with the new one. If they're different, it will be difficult to insert the new sash in its proper slot and will affect how well the sash functions. Luckily, this is easily fixed by placing tabs in the correct locations on your new window.
In addition to the sashes, you'll also need to check the frame of your windows for problems or rot. It's a good idea check it regularly since wood shrinks and becomes less durable over time, especially with exposure to the elements. 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 with half mineral spirits and half boiling Linseed oil. After the treatment has dried, you can restore your frames using the finest latex paint. A fresh coat of paint can also shield your window from the elements.
