FENSA certified installers are able to help you repair or maintain your double-glazing to meet the energy efficiency standards of legal compliance and resale prices.
Broken Panes
A broken window can create a lot of problems, as it could hinder airflow, light, and even pests. While you can certainly employ a professional to fix the broken pane but you can also repair the damage yourself at only a fraction of the cost.
To do this, you need to remove the old pane. Begin by putting on protective glasses, gloves for work and a dust mask to protect yourself from lead shards and glass dust. Set up a level surface in an area that is well ventilated. You should also place a drop cloth underneath the work area to catch any loose glass that is being removed. It is a good idea to keep a HEPA vacuum close by to remove dust, debris, and hazardous waste while you work.
Make use of a utility knife to scrape the old glazing putty off once the old window is removed. Be careful not to scratch the wooden frame of the window. If the old putty is particularly stubborn, try using a heating gun to soften it before scraping it off with the knife. Make sure you wear safety glasses when using a heat gun, and be cautious to avoid putting hot wood or glass pieces in your eyes.
The next step is to prepare the frame to accommodate the new pane. Take measurements of the opening and subtract 1/16 inch both ways to account for expansion and contraction of the wood. Then, let the local hardware store cut you a piece double-strength glass that fits the opening precisely. Before fitting the new glass dry-fit it for a snug fit.
After you have installed the new glass then apply a small amount of caulk made from latex to the outside of the opening to create a weather seal. Then, you can install the glazing points to secure the new pane in the proper position. Typically, you will need two points on each edge for windows of standard sizes.
Once the new glazing compound is dry and dried, you can paint it over to match the frame. If you are concerned about cracks then you can use masking tape that is heavy-duty to prevent superficial cracks from getting worse.
Frames that are damaged
The first thing to do is inspect the frame. You'll need to have it repaired professionally if there are cracks or corrosion or rust or if the frame is broken into two pieces. Metal frames can't be joined by glue and trying to solder or weld them yourself can cause permanent damage.
If Window Glazier and Glazing is not damaged, you can apply a small amount of brush and a bit of conservation detergent or water to wash the frame thoroughly. This will remove any dust, grease or dirt that has built up over the years. Cleaning antique frames with ornate carvings or gesso may reveal the original finish beneath the dust.
If the frame is damaged, you will need needle-nose pliers with a flat surface wood putty, sandpaper and a small clamp. Start by taking off the glass, photo and the back of the frame. Take care to remove the frame at the corners where there are nails or brads. Remove the joints and open them up. any glue that is old. Apply new glue.
Loose Compound
The glazing compound that holds the glass panes within their wooden frames is an important part of the energy efficiency of any historical building. It seals the wood, bonds the glass to the frame and sheds moisture to prevent water damage in the course of time. Cracks or gaps in this compound can cause air infiltration, which decreases the insulation value and can increase the cost of utility. Making sure you are keeping up with repairs on your double-glazed windows will help keep them running smoothly and efficiently.
The weatherstripping may be worn out or loose if you notice drafts in your window frames. This seal can help reduce energy costs and increase comfort. If you hear loud sounds outside, such as traffic or machinery, this could mean that the glass tape is worn out.
Remove old tape from the edge of the frame and thoroughly clean the frame. Apply a new piece tape to the frame's edge and press it down firmly. This tape can be found at any hardware shop and is an inexpensive method to boost the performance of your double-glazed window.
Standard super glues are great for wood, metal, and other common materials. However they're not suitable for glass surfaces. Look for a glass-based adhesive, such as Loctite Extreme Glue Gel. This kind of glue is designed to withstand UV light and moisture, which makes it a better option for repairing double-glazed windows.
You'll need to use a degreaser on the exterior of your window frame and sash prior to when you begin the process of repairing it. This will ensure that the new glue adheres correctly. Then, prepare the area to be glazed by priming it with an oil-based primer. Make sure to prime the entire surface including the back of the sash where it rests within the frame.
It is possible to repair most double-glazed window problems however, if the windows are severely damaged or do not provide enough insulation, replacement may be the best option. Consult with an experienced glazier or handyman to make the right decision. Regular maintenance and repairs can keep your windows looking great for many years.
Foggy Panes
Foggy windows happen when the window seal fails. This allows air to penetrate and slowly build up moisture between the glass panes. Foggy windows can lead to a number of problems, from condensation and calcium deposits to black staining and fungus. It's not just ugly but also leads to lower energy efficiency as well as increased heating or cooling costs. However, it is possible to resolve the issue. Foggy windows are usually caused by a simple water buildup, so the initial step is to get rid of as much of the moisture as is possible. This can be accomplished by applying a defogging spray or shaving cream. If these measures don't work, it's time to contact a professional.
Double pane windows are able to work because of the space between them. The space is filled with argon, or krypton. These non-toxic gases are more dense than air and slow heat transfer. If the gas has leaked out the windows, they aren't being insulated properly. Replace your windows with IGUs to fix the fogging and restore your home's efficiency.
Many homeowners are under the impression that they must replace their entire window when it becomes foggy, but this is not always the situation. Some glass shops will replace the insulation unit (IGU) only, without replacing the entire frame or sash. This is a cheaper solution and is just as effective in fixing your windows.
While there are a few DIY remedies to prevent window condensation, like shaving gel or defogging cream, it's best to call a professional so that the job is completed safely and in a correct manner. A window repair professional will make holes in the glass and then inject a cleaning solution into the space between the panes. The window repair expert will clean the stained surface and dry the inside to restore the appearance and function of the window. To learn more about this procedure, or to schedule a no pressure in-home consultation, contact a local expert in window replacement and repair.
