If the crack is extensive or appears to be getting worse, you should consult a professional. A skilled glazier can determine the root of the problem and recommend an appropriate repair procedure.

An impact crack is the most common type of window break, usually resulting from a solid object hitting your window with enough force to fracture it. These cracks are typically with a starburst-like pattern of lines and broken pieces that could be risky if they break loose. If you have double-pane windows, this crack could compromise the gas layer between the panes, which can affect your window's energy efficiency.

Another type of crack is a stress crack, which can develop gradually as time passes, due to extreme temperature fluctuations or other environmental factors. These cracks start around the edges of your window and can eventually expand into full-blown break.

A pressure crack is a more severe crack but it is still able to be repaired. It is a curvy straight line that can stretch across the window on one or more sides. It could be caused by high or low pressure, which can cause the glass to expand or contract.

Leaking Windows

If you notice a damp spot under your window, or you notice that the wood around it is weak or decaying, it might 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 decrease indoor air quality, lead to sagging drywall and even worsen allergy symptoms. If not addressed they can cause structural damage to the house.

It's best to call a professional if the water is visible or coming from outside. Leaking windows are one of the main causes of mold and structural damage and should not be left untreated.

In many instances caulking is a great option to stop leaks. It is important to clean the area first, though, and get rid of any old caulking prior to applying a new layer.

Check the weepholes on the frame for any debris. These holes are designed to drain excess rainwater, but they can also become blocked over time with insect corpses or other debris.

If windows have double panes You'll also have to inspect the seal between the glass and the metal frame. This will help maintain a seal between the glass panes and make the windows more efficient. The seal could wear down with time and let water enter the home.

Water stains on ceiling and walls are another indicator of leaks. The drywall will turn discolored once it is saturated by water. Peeling paint is another indication of water affecting the adhesive properties of the paint and pulling it from the wall.

Faux Muntins & Mullions

In the past, mullions and muntins (or glazing bars in the UK) separated and held panes of glass in the classic multi-pane windows. After WWII, larger expanses glass that were tempered became available. Today, they're only used as a decorative element in some older homes.

Sometimes it is the case that a small or even a single group of these wooden supports may get damaged by wind or rain and cause cracks to the window. Repairs can be made to the majority of these brittle or rotting parts.

First employ a rag to clean the affected areas. Use ammonia-based cleaning products that does not leave traces. Take off any rotting or loose pieces and cut the intersections of the painted vertical and horizontal window muntins with an exacta knife. After you've cut the intersections, tape off the lower portion of the window frame with painter's tape. Now, you're able to apply a heavy coat of white paint, paying close attention to areas which were lightly coated on the first pass. Allow the paint to fully dry before removing the masking tape and applying the second coat.

If you're dealing with an issue that is more serious, such as cracks that form an hourglass shape in middle of the window it's likely to be recommended to replace the sash. In such cases you'll need to search for a replacement that is similar to the window that is in place in terms of the design and size.

For a less expensive alternative, you can also install an attached grid window. These windows come with a complete pane of glass, with muntins that are that are glued to the surface, giving them a divided look. These windows are not as energy-efficient as traditional ones.

Installing a drip-cap will stop water from getting into the window frame. Most home centers sell these drip caps in aluminum for about $20. They are much easier to install than replacement windows sashes, and will provide the same functions as a real mullion or a muntin.

Broken Sashes & Frames

A broken window sash should be a sign that you need to contact a professional. A damaged sash, left unchecked can cause water leaks, wood decay and other serious issues to the frame and sill. If you've broken a window sash, replace it as soon as possible to ensure that your window is properly sealed and functioning.

The issue is usually caused by worn-out or poorly installed cords. Luckily, replacing them is fairly easy and can be done in the majority of double-hung windows. To begin, you'll need take off the tabs of metal that hold the sash in place. Then, push up on the other side of the sash (it doesn't matter which side) and then pull it towards the opposite side in order to remove it. You'll want to carefully remove the strip of separation that is what separates the sash from other so you can access the area where the sash cords reside.

It is important to compare the metal tabs of the old sash with the new one. If they're not the same, it will be hard to put the new one in its slot and impact how the sash functions. This can be easily corrected by placing the tabs at their correct locations on your new window.


In addition to the sashes, you'll also need to check the frame of your window for problems or rot. This is a good thing to do regularly, as wood shrinks and wears down as time passes. If you spot any obvious damage, it should be repaired as soon as you can, to avoid an even bigger issue from arising.

If your window frames are in poor condition you'll need to treat them with a homemade preservative created by mixing half mineral spirits with half boiling linseed oil. After the treatment has dried for two days, you can re-finish your frames using high-quality latex paint. A fresh coat of paint can protect your window from the elements as well.
