When It's Time to Repair Windows
It is essential to be cautious when you are repairing windows. First, you should put on a pair cut-resistant gloves and safety goggles to stop glass shards from cutting you as you work.
An easy fix for a window that is broken is to put a plastic cover over the crack. This will keep rain, snow and insects from getting into your home.
Cracked glass
Glass that is cracked not only makes your home look less appealing but also allow drafts and other elements to enter the house. It doesn't matter if the cracks are caused by an impact like soccer or baseball, or stress, like a sudden temperature change, it is important to have them repaired as soon as you can to prevent further damage and to keep your windows working correctly.
Use clear tape to cover the cracks in your window if it's not damaged. It's a simple and inexpensive solution that will provide some protection from water, dust bugs and other particles, as well as keeping out the elements.
If the crack is extensive or is getting worse, it's recommended to consult an expert. A glazier who is experienced can determine the root cause of the crack and recommend an appropriate repair procedure.
Impact cracks are the most common window breakage. They usually occur when a sharp object strikes your window with enough force that it cracks. These cracks are usually accompanied by a starburst pattern of lines, and shattered pieces that can be quite dangerous if they fall loose. The crack could affect the gas in the panes of the double-pane window and decrease its energy efficiency.
Another kind of crack is a stress crack, that develops slowly over time because of extreme temperature changes or other environmental factors. These cracks usually begin near the edges of your window and eventually grow into full-blown cracks.
A pressure crack is a more serious crack however it can be repaired. It's usually a curvy line that extends across one or more sides of your window. It could be the result of high or low air pressure that can lead to expansion or contraction of the glass.
If you're ready to take further than nail polish and tape, there are alternatives to fix cracks in your window glass. A product like Glass Repair Film is a little more expensive, but will offer a bit more protection and durability for your windows. If you prefer to go the DIY route epoxy is a durable adhesive that can fill in cracks to help keep them from getting worse and make your window look like it has never had cracks in the first place!
Leaking Windows
If you notice a damp zone under your window, or the wood around it appears soft or rotting it could be time to replace your windows. Mildew and mold thrive in excessive moisture and can cause various issues within your home. They can lead to indoor air pollution, sagging drywall, and even worsen allergies. Unchecked, they may also cause structural damage to your home.
If the water is coming from the outside or is visible through the frame it's a good idea to get a professional to assist to fix the problem right away. Leaking windows are among the leading causes of structural and mold damage and should not be left untreated.
In many cases, a simple layer of caulking is all you need to stop leaks. It is important to clean the area, though, and get rid of any old caulking prior to applying a new layer.
Check the weepholes on the frame for any debris. They're designed to drain off excess rainwater, but they could be clogged by insect corpses and other debris in time.
If window repairs have double panes, you'll also need to examine the seal between the glass and the frame. This creates a barrier of gas between the panes, which makes the windows more energy efficient. Over time, the seal can get worn out and let water into your home.
Water stains on ceiling and walls are another indication of the presence of a leak. These occur when drywall is saturated by moisture, which weakens its fibers, causing discoloration. There is also the possibility of peeling paint, which is a result of water destroying its adhesive properties and tearing 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 tempered glass were available. They're mainly used as a decorative feature in some older homes.
Most of the time it is the case that a small or even a single group of these wooden supports can get damaged by wind or rain, leaving cracks in the window. The good thing is that you are able to repair the majority of these decaying or brittle parts.
First take a rag and clean the affected areas. Make use of a cleaner based on ammonia that doesn't leave any residue. Remove any loose or rotting pieces and cut the intersections of the painted vertical and horizontal window muntins with an exacta knife. After you've trimmed the intersections, tape off the lower portion of the window frame with painter's tape. Now, you can apply a thick layer of white paint, paying particular focus on the areas that were lightly coated in the first go. Allow the paint to completely dry prior to taking off the masking tape and applying the second coat.
If you're experiencing an even more serious issue, such as cracks that form an hourglass shape in middle of the window, it's better to replace the sash. In these instances it's crucial to find the right replacement window that matches the style and size of the existing one.
For a less expensive alternative, you can also install an attached grid window. These windows are constructed of a complete glass pane that has a series of muntins that are glued on the surface. This gives them a divided appearance. These windows are not as energy-efficient as traditional ones.
Installing a drip-cap will stop water from entering the window frame. There are a variety of these aluminum drip caps at the majority of home centers for around $20. They're much simpler to install than a replacement window sash, and they'll provide you with the same function as a genuine mullion or muntin.
Broken Sashes & Frames
A broken window sash is an obvious indication that it's time to seek some help. A sash that is broken left unchecked can cause water leaks, wood rot, and other serious problems to the frame and sill. If you have a broken sash you should replace it as soon as you can to ensure that your window is properly sealed and working.
The problem is often caused by worn-out or poorly installed cords. Luckily, replacing them is fairly easy and is possible in all double-hung windows. To begin, you'll need dislodge the metal tabs that hold the sash in place. Push up on the opposite side of the sash (it isn't important which side) and then pull towards the opposite side in order to remove it. You'll want to carefully remove the parting strip that divides the sash from the other so you can access the area where the sash cords are.
It's important that you check the metal tabs on the old sash to those of the new one. If they're not the same it's difficult to place the new one in its place and could affect the way it operates. Fortunately, this issue can be fixed by placing tabs in the correct places on your new window.
You'll need to inspect your window frame as well for any damage or rot. It's a good idea perform this inspection regularly since wood shrinks and wears down over time, particularly after exposure to the elements. It is important to repair any visible damage as quickly as you can, to avoid a more serious issue.
If your window frames are in poor condition, you'll need to treat them using a homemade preserver made using half mineral spirits and half boiling the linseed oil. After the treatment has dried, you are able to restore your frames using high-quality latex paint. A fresh coat of paint can also shield your window from the elements.
