Do-It-Yourself Double Glazing Repairs

Double glazing can keep a building warm, but it may be prone to problems as time passes. Leaks, broken glass, or foggy windows are all issues which can cause energy loss, expensive repairs and health problems.

FENSA certified installers can help you repair or maintain your double-glazing to meet the energy efficiency requirements of compliance with the law and resale prices.

Broken Panes

A broken window can cause a lot of issues, since it could block air, light and even pests. While you could certainly employ a professional to fix the damaged window but you can also fix the problem yourself for a fraction of the cost.

You’ll need to take out the old window. Start by putting on safety glasses, work gloves and dust masks to shield yourself from glass shards as well as lead dust. Set up a stable surface in an area that is well ventilated. It is recommended to put a drop cloth under the work area to catch any loose glass as it is removed. It is recommended to have a HEPA vacuum nearby to remove dust, debris, and hazardous waste when you work.

Once the old window is removed, use a utility knife to scrape away the old glazing putty. Be careful not to damage the wood frame of the window. If the old putty seems particularly difficult to remove, you could try using a heating gun to soften it prior to scraping it off with the knife. Make sure you wear safety glasses when working with a heat gun, and use caution to avoid putting hot glass or wood fragments in your eyes.

The next step is to prepare the frame for the new pane. To account for wood expansion and contraction take the opening measurement and subtract one-sixteenth of an inch in both directions. The local hardware store will cut a piece of double strength glass to precisely fit the opening. Before you install the new glass, dry-fit it to ensure an ideal fit.

After you have installed the new glass, apply a small amount of caulk made from latex to the opening’s perimeter for an airtight seal. The glazing points are then placed to secure the new pane. For standard sizes of window glass it is only necessary to install two points per edge.

After the new glazing compound has dried you can then paint it to match the rest. If you’re concerned about the potential for cracks you can apply a heavy-duty strip of masking tape in order to keep superficial cracks from getting worse.

Frames that are damaged

It is recommended to inspect the frame first. You’ll need to have it fixed professionally if there are cracks or corrosion or rust or if the frame is broken into two pieces. Metal frames are not able to be glued and any attempts to solder or weld them will cause permanent damage.

If the frame has not been badly damaged It can be cleaned using a small brush, some detergent for conservation and water. This will remove any grease, dust or dirt that has built up over the years. Cleaning old frames with intricate carvings or gesso can reveal the original finish beneath the dust.

If the frame has been damaged, you will need needle-nose pliers and a flat surface, wood putty, sandpaper, and a small clamp. Remove the back, the photo and the glass of the frame. Carefully pry the frame apart at the corners, where you will see brads or nails. If possible, you can open the joints, scrape off any glue that has been used and apply fresh glue.

Loose Compound

The glazing compound that keeps glass window panes within their wooden frames is an essential part of any historic building’s energy efficiency. It seals the wood, bonds the glass to the frame, and sheds moisture to prevent water damage as time passes. The compound may crack or have gaps that let air in, lowering insulation values and increasing utility bills. Keep up with the repair work on your double-glazed window to keep them running smoothly.

The weatherstripping may be worn out or loose if you see drafts in your window frames. Replacing this seal reduces the energy costs and improves comfort. If you hear loud noises outside, like traffic or machinery, this could mean that the glass tape is worn out.

Remove the old tape from the frame’s edge and thoroughly clean the frame. Apply a piece of new tape to the frame’s edge and press it down. It’s available at any hardware store and it’s a cheap method to increase the performance of double-glazed windows.

While the standard super glues are effective to bond metal, wood and other common materials, they’re not suitable for glass-based surfaces. Look for a glass-based adhesive, such as Loctite Extreme Glue Gel. repairmywindowsanddoors.co.uk of adhesive is made to resist UV and moisture light which makes it a great alternative for repairing double-glazed windows.

Before you start repairing your windows, you’ll need to clean the surface of the frame and sash using a degreaser to ensure that the new glue is able to stick. Prepare the area that will be glazed using an oil-based primer. Be sure to prime the entire surface, including the back of the sash, where it rests within the frame.

While you can repair many problems with double-glazed windows, if they are severely damaged or don’t provide effective insulation, replacement might be the best option. Talk to a glazier who is experienced or handyperson to make the best decision. Regular maintenance and repairs will ensure that your windows are looking their best for a long time.

Foggy Panes

Foggy windows happen when the window seal fails, allowing air to penetrate between the glass panes and slowly build up moisture. Foggy windows can lead to various issues, ranging from condensation and calcium deposits to black stains and fungus. It’s not just ugly but also causes an increase in energy efficiency as well as increased heating or cooling costs. Fortunately, the issue can be resolved. Foggy windows can be caused by a simple buildup of moisture, so the first step is to remove as much moisture as possible. This can be accomplished by spraying a defogging agent or shaving cream. If none of these solutions work you need to call in a professional.

The reason double pane windows work is due to a space between them. The space is typically filled with argon and krypton which are non-toxic gasses that are more dense than air and can reduce heat transfer even more. If the gas is leaking out, your windows aren’t adequately insulated. Replace your windows with IGUs to fix the issue and improve your home’s efficiency.

Many homeowners believe that they need to replace their whole window if it starts to get foggy, however 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 that can be just as effective at fixing your windows.

Although there are a few DIY solutions for window condensation, including defogging spray or shaving cream but it is advised to consult a professional ensure that the job is done correctly and safely. A window repair expert will cut holes into the glass and then inject a cleaning solution into the space between the panes. They then clean the surface that has been soiled and dry the interior of the window, thus restoring its appearance and functionality.
