Sash Window Repair

Sash windows can go out of balance and even break. Pam browses the internet for wavy glasses that are salvaged and keeps an eye open for discarded metal sashweights. She then hunts for replacements in the form of nuts or washers to balance her window.

Pam will set each pan by putting the glazing material in a rope into the rabbet groove, or pocket around the opening. This prevents drafts and costly heat loss.

Sticking Sashes

If your double glazing repairs-hung windows get stuck and shatters, it's a nightmare. They'll rattle in the event of a storm and you'll lose your view. On the other side, a window that's too loose will let external air and noise in and your energy costs may increase. Neither scenario is optimal, window repairs but both can be fixed with the appropriate tools and determination.

Paint can get splattered on the channels of old weighted sash window tracks, causing them to jam. Most of these problems can be resolved by cleaning and oiling the tracks.

Begin by removing the old caulking between the window stop (the interior one) and the window frame. Scrape away any paint that has accumulated. Use a sharp knife and place plastic sheets and a dust-collecting vacuum cleaner below the surface to collect any paint dust or chips.

Then, clean the tracks using a dry cloth, and apply a silicone lubricant for better glide. The lubricant can be found at many home improvement stores or online. Then move the sash up or down to test it.

If it is still jamming it could be a problem with the sash cord. Verify whether the cord is tangled or hanging in the sash or snapped. If this is the case, you'll need to replace the window's cord.

A pin that holds the rail in place could have fallen out. It can be difficult to fix and you will need to call in a professional most times.

They are often caused by rotten wood, cracked putty, worn sash cords or unbalanced weights which can allow cold air to get in around the window, making it difficult to keep your home warm.

Cling film can also be used to stop drafts. Simply roll it up and push it into all the gaps that surround your window. This is a good draught-stopper, but it can also hinder the sash's movement and even cause a fire. The sash needs to be removed to open the window and the clingfilm needs to be to be applied every time the sash is closed.

It is possible to use a sharp knife for removing them if they are painted or nailed into place. Once the pockets are gone, you can begin to remove any wood rot and apply a good quality, water-resistant wood filler. Once the wood filler has dried the primer coat must be applied to stop further decay.

It is a good idea to check the sash's weights inside the window as well to ensure that they are balanced and not pulling one side more than the other. The sash can be thrown off its track if they are not balanced. This could cause the frame to break or be damaged.
