What NOT To Do In The Window Repairs Industry
Window Repairs For Hard-To-Reach Areas
A damaged window is an urgent problem which must be addressed before the weather turns too cold. This is true especially in the event that the mullions and muntins holding the glass are cracked or have indications of decay.
A simple, inexpensive solution is to apply a thin layer transparent shellac (or nail polish) over the crack. This will close the crack, decrease the stress it places on it, and also stop air from spilling out.
1. Tape
If you're in a bind and don't have time to wait for a window repair professional service, the most efficient solution is to simply place some strips of tape on the crack. This will do a good job stabilizing the crack and lessening the strain on the glass, and it will also prevent cold air from getting into your home through the window frame.
Another benefit to this type of quick repair is that it's affordable and easy to complete. If you are in this situation repeatedly, it could be worthwhile to invest in a high-quality masking tape. This will be capable of enduring more abuse than your standard tape at home, and will also last much longer.
You can apply clear nail polish to temporarily fix cracked windows as well as the masking tap. It might not be as attractive as tape, but it will do the job to hold the crack until you can find a better solution. You'll need to clean the crack thoroughly before applying nail polish. A second coat might be needed after the first has dried to fully fill it in.
Another alternative is to cover the entire frame of your window in self-adhering flashing tape ($12, The Home Depot). This product creates an completely waterproof barrier that can keep out rain, snow and wind. It can also help to stop cold air from getting through your windows. Just be sure to clean the surface and apply a little of linseed oil before you attach the tape, which will make it stick to the surface.
Duct tape can also be useful for wrapping extension cords to prevent them from rattling on the windows' interiors. Just be sure to wrap it securely and assign a colour to every type of cord so that you are able to easily determine the type of cord you're using before you use them. This will prevent you from having to untangle your extension cords in the winter.
2. Glass Repair Film

A broken window is an expensive and inconvenient issue. Not only can it create a security issue by creating an entry point for burglars, but it also reduces the amount of natural light and airflow in the building. This is why it is crucial to find a quick and efficient solution to fix the window, particularly when you need to stop further damage to the frame or surrounding materials.
In certain cases, the cracking of a window glass is too severe to fix using clear tape and will require professional glaziers to replace the glass pane. This is particularly true if the window has double-pane glass because a serious crack could weaken the gas layer between the two panes, and decrease the energy efficiency of windows. In many instances, a damaged glass window can be fixed using a simple film.
This tough and durable temporary repair film is designed to be put on already broken and cracked window glass to secure it temporarily. This film is often used in schools and hospitals to make glass weatherproof and safe after breakage. The film is optically transparent so that it doesn't interfere with the view through the window. It can be applied easily to laminated and flat toughened glass. It is twice as strong than standard window films for safety and can be used to create a safer and more attractive and pleasing setting.
The film is easily applied using a razor blade or knife. It is similar to sticky-back plastic, and can be cut to a desired size. The film is then covered with a layer of release liner that has to be removed before it is smoothed by a cloth. This makes the window weatherproof, safe but still allow sunlight to enter.
It is a much cheaper alternative than hiring a glazier to board up the window. It can avoid further damage to the glass, frames, or even the surrounds. It is also quicker to put in place than traditional boards up, and helps reduce OHS concerns with dangerous glass shards.
3. Epoxy
Epoxy is a flexible and increasingly sought-after product to repair wooden surfaces. More Boston Building Resources members are using it to reinforce porch columns, repair rotting window sills and door jambs, as well as other wood components for exterior use that are expensive or difficult to replace or remove. It starts as a caulk-like material and can be shaped like cookie dough, then molded into rough shapes, carved and sanded, much like wood. repair upvc windows when dried and, unlike other exterior wood fillers, won't break or crack as it cures.
Epoxies are a broad class of glues that require two parts to mix before they set and are sometimes referred to as epoxy resins or epoxy binding agents. They are formed from long chemical chains, called monomers, which are held together by heat and pressure. They can be tinted with a specific color or are clear and are utilized on all kinds of glass that are laminated, plain, tempered and mirrors.
To apply epoxy, place clean, dry cardboard on the area to work in and work in a well-ventilated space. It takes about a minute for the epoxy to set up and set, so make sure you have the tools in place and ensure you are in the right mindset for this kind of project. If possible, separate any broken pieces of glass to prevent them from breaking again when the epoxy sets.
If you're using liquid epoxy, follow the directions on the bottle. If the epoxy dries out too quickly you can heat it up with an iron or a hair dryer. Be cautious not to overheat the epoxy, or it could harden and lose its capacity to form. The heat can also affect the durability and strength of the bond.
Once the epoxy is smoothed and shaped then it needs to be sanded with 80-grit sandpaper to prepare it for paint. Wear a dust mask while sanding, and sand all the wood around the epoxy to roughen it up so that paint can adhere.
Epoxy can be used to repair small chips and cracks in windows, but it's not a good choice for repairing structural joints, where the wood dutchman, scarf or splice method would be more appropriate. Also, if you are working on a structure that is older repair with epoxy could be considered irreparable, and repairing the damaged part is preferable.
4. Glass Replacement
Window repairs are one thing, but windows situated in hard-to-reach areas like dormers or upper floors require extra care and attention to ensure they're secure and working properly. These windows, whether they have broken glass or are difficult to open or close, could be energy drainers and security risks.
These types of repairs can also be handled by window repair professionals. First cleaning the windows is done to ensure there are no lingering fragments of glass within the frame or mechanism. Then, they remove the sash, or moveable part of the window which allows it to open and close, from the frame. Once this is done, the glass pane can be removed. For this the professional will be required to wear eye protection and gloves. The professional will also need to take off any glazing compound or points which are similar to putty fasteners to hold the window panes in place. Then, they will seal the shattered areas of the window with tape to shield themselves from the dangerous razor-sharp edges of the glass that has been broken.
Once the glass is removed, the window is prepped for a new glass replacement. You can use a utility knife to scrape off any remaining glazing compound inside the window frame. A wire brush can assist in removing any paint, dirt, or other residue that might be trapped in the smaller crevices of the window frame. This will make the sash more secure and fit better within the frame when it's replaced.
This repair procedure for windows is a lot simpler for single-pane windows compared to for triple-pane or double-pane windows, as the professionals will need to replace both the pane as well as gas and spacers with new ones in order to restore the window back to its original aesthetic. This type of window repair is cheaper than replacing the entire window.
It is important to keep in mind that damaged window frames and sills can lead to wood damage, rot and water leakage, which can be very expensive for homeowners to deal with. If these issues aren't addressed they could be transferred to other areas of the house and cause more problems. It's better to invest in low-cost window repairs and identify these problems early.
