5 Lessons You Can Learn From Window Repairs

Window Repairs You Shouldn't Ignore

If your window isn't able to open and close smoothly it could be a sign of a leaky seal. The expansion and contraction caused by heat over time can cause damage to seals between double panes which can lead to dirt, moisture and energy loss.

Wood rot is also a common problem in window frames and sills. Repairing the wood early with epoxy filler can save expensive repairs later.

Chips and cracks

A damaged window isn't only ugly, it can be a risk. It exposes the glass to more cracks and also moisture, which can cause mold problems. If you want to ensure that your family is safe and your windows intact it is essential to repair any cracks or chips immediately.

The most common items that can crack your window are rock chips, pebbles dropped by the car in front of you, and even Dolichovespula maculata seeds (no, that's not an actual plant, it's a bug). These cracks can be repaired.

This repair technique works for single-pane household glass, and double-pane windows with cracks in just one glass pane. It won't work for windshields that require a specific tool to inject resin into the crack and create an air gap between the glass layers.

First clean the area in which you're planning to repair the crack with glass cleaner. Then you can use a pin or thumbtack to remove any loose shards of glass in the crack. It is also recommended to clean the surface with rubbing alcohol or acetone to ensure proper adhesion of the repair material.

Some methods suggest that a repaired crack will be nearly invisible. While this is true for some types of repairs however, it's not a practical goal for many, especially for small cracks in the glass. However, repairing these cracks can prevent them from becoming larger problems and could stop them from spreading.


If you do want a perfectly invisible crack, look for an repair kit that makes use of a transparent super glue to repair the damage. This kind of glue doesn't expand when it dries and won't cause more damage to the crack. Be sure to go through the directions for the product you are using before making the decision.

You can cover a slit with clear nail polish to provide temporary relief. This will act as a sealer, and slow the progression of the crack. It's crucial to apply the polish a little bit outside the edges of the crack to prevent damaging the integrity of the windshield.

Sashes that aren't moving

Some old windows are difficult for you to open due to swelling wood or rotten wood or because the balance systems that move up and down can be damaged. Often, the problem is much simpler. It could be dirt or other debris that has blocked the mechanisms. It could be that the mechanism needs to be cleaned or lubricated.

The first step is to unhook the sash from its frame. You can do this using a putty knife and a bit of grit. First score the paint between the sash stop and jamb Then, carefully pry them apart. Place the pieces aside so that they don't get damaged.

After you have removed the sash, will be able to access the pocket piece and the front window stops. You can take them off using the help of a utility knife and then lower the top sash down to the sill. The bottom sash isn't as difficult to move as the top but getting it all the way down can be a challenge as well. After you've lowered the sash down to the lowest point, use a flathead screwscrew to reset and lock the balance shoe (the small box that is located at the bottom of your window) so that it can be able to support the weight of the sash.

If the sash doesn't stay in place, you could require replacing either the balance system or sash. It's typically easier than you think to replace the balance system or sash, since replacement parts are available from many different vendors and aren't too expensive. Once you've replaced the balance system or sash you can move the sash around and test it to see whether it functions properly.

Another issue that can cause windows to be difficult to open is the fact that the tilt pin for the sash is missing or is damaged during cleaning. If you are adept, you can repair this yourself. But it is recommended to only do it on older windows which are safe to disassemble. If not, it's better to contact an expert who is familiar with the particular type of window you own.

Caps with drip Caps

If you're experiencing dampness around your window it may be the perfect time to invest in new drip caps. The L-shaped flashing is put on the top of the window after installation, but before siding. It helps to direct water away from your frame. This quick project can help to prevent damage from moisture and save you money on maintenance costs.

The addition of an end dam to your window cap flashing may also prevent water infiltration at the ends of the trim. Use a pair Tin snips and make the small "flap". This fold will stop rain from rolling down the ends of the flashing and into the wood framing.

You can also purchase drip caps from MS Windows and Doors that already have been fabricated with an end dam included for you. These preformed drip cap are available in a range of color options and can be added when you order your window.

Install the head flashing underneath the sheathing which is above the drip cap. This is the same type of flashing used under the j channel on your exterior trim. It's a good idea avoid tape covering the entire length of the head flashing, and to only cover the corners.

The head flashing is cut at a 45 degree angle on each corner to create a small flap, and then it's folded down and taped over the sheathing.  double glazed window repairs near me  creates a small exit for any water that might pass through the WRB and into the sheathing of the house above the window.

Once you've secured the drip cap to the sheathing you can apply caulk along the top edge of the cap. This will keep the moisture from getting into the wood of your housewrap or window sill and housewrap, as well as the siding that is above the window. Be aware that moisture could cause structural issues and wood rot, therefore it is recommended to keep moisture from entering your home.

Sash Weights

The weights that are placed on windows (also called sashweights, or sashlines) help balance the sashes and prevent them from moving when they are opened. The weights may need to be replaced, or they could simply be tangled and need to be loosened. It is also possible that the counter balances will need to be replaced.

Pam examines the outside of the window first, to make sure there aren't any visible damage or rots that must be dealt with prior to beginning the work. If there is, she'll have to do the repairs before trying to restore the windows.

She starts by removing the parting stops and interior sash stop on both sides of the window. To accomplish this, you'll need to score the paint line using a utility knife on both sides of the interior sash stop and then remove it using a wooden tool. Pam says that this step is essential because when you use mallets to remove stops, they may crack or split. She recommends using small woodworking tools with a narrow blade.

After removing the stops she can then remove the sashes. She will remove the bottom sash first, and then the top. Pam Lubricates the sash cords in order to allow them to move smoothly. She then pulls the cord and locate the metal hooks connected to each sash. Usually, they are damaged and need to be replaced. Then, she pulls one of the old sash weights out of its pocket and screws in an entirely new one.

She evaluates the weights by weighing the sash using a scale to see how much it weighs. She replaces the weight with one that is equal to the weight of the sash. The process is repeated for the second sash to ensure it is properly balanced. After the sashes are placed back into place, she uses a level to check that they're in the right place. She also makes sure that the cords are lubricated to let them slide freely and then tightens the counter balance hooks.
