Pam will bed 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.

Sashes that stick Sashes

It's a nightmare when double-hung windows are stuck. They'll be difficult to see when they squeak during a thunderstorm. A window replacement that is too loose could let air and noise in which could increase your energy costs. Both of these scenarios are not ideal, but they can be rectified with the proper tools and persistence.

Paint can accumulate on the channels of old weighted sash window tracks, which can cause them to become jammed. Luckily, most issues with this can be solved through cleaning and lubricating the tracks.

Remove the old caulking from the space between the window stop (the one on the inside) and the frame of the window. Scrape off any paint that has built up. Make sure you make use of a sharp blade and then set up plastic sheets and a vacuum cleaner directly below to contain any paint dust and chips.

Clean the tracks using a dry cloth, and Glaze then apply a silicone-based lubricant to make them more gliding. The lubricant can be found at many home improvement stores or online. You can test it by moving the sash upwards or downwards.

If it continues to stop it could be faulty. Examine the sash cord to determine if the cord is catching or hanging up in the sash, or has snapped completely. If this is the case, you'll have to replace the window's cord.

Another reason for the jam could be that a pin that holds the meeting rail in place has fallen out. It can be difficult to fix and you will need to call in an expert most often.

If a pin isn't falling out, but the wood has gotten swollen or warped it's recommended to apply a wood hardener to it. This liquid dries quickly and can restore damaged wood. It's not necessary to take out the windows on your sash to repair them.

Draughts

Draughts can be a major issue for windows with sash windows that are old particularly in winter months. They can be caused by rotten wood, cracked putty, or worn cords for sash. This causes cold air to seep around the window, making it more difficult to heat your home. You can prevent drafts by filling the gaps with expanding foam, or by using draught-proof strips that are available at most hardware shops.

The sash needs to be removed to reopen the window and the clingfilm will need to be applied every time the sash is closed.

A better option is to have your windows draught-proofed as part of a comprehensive refurbishment service. This can include the installation of new sash strings, parting beads and staff beads, the lubrication and rebalancing the weights, as well as the fluidization and rebalancing of the pulley wheel. It could also involve painting or staining of the frames and the sashes. This could restore the sash to its original purpose, improve its energy efficiency and fix any minor imperfections in the wood. It's less disruptive than removing the windows, and can reduce draughts, improve the thermal efficiency and dramatically reduce costs.

Decay

The "pocket covers" are tiny pieces of wood placed on the frame's side that permit access to the weights must be removed. These can sometimes be nailed in place and stuck with paint, so you'll likely need to use a knife to get them out of the way. Once the pockets are removed you can begin to remove any wood rot, and then apply a high-quality water-resistant wood filler. Once the wood filler has dried it is recommended that a primer coat be applied to prevent further decay.

It is a good idea to check inside the window the weights of the sash to ensure that they are balanced. They should not be displaced or pulled one side more than the other. The sash may fall off its track if they aren't properly balanced. This could cause the frame to break or be damaged. The sash weights can be replaced with new ones or a new mechanism for balancing can be fitted that will stop the sashes from bouncing to the wrong side of the window frame.

Poor Security
