Sash Window Repair
Sash windows could be out of balance or break. Pam browses the internet for salvaged wavy glasses, and keeps an eye out for discarded metal sashweights. She then searches for replacements, such as nuts or washers, to ensure that her window is balanced.
Pam beds each pane with a rope of glazing compound she works into the rabbet groove, or pocket, which is located around the opening. This helps to reduce drafts and costly heat loss.
Sashes that stick Sashes
If your double-hung windows get stuck, it's an absolute nightmare. They'll rattle during a storm, and you'll lose your view. On the other side, a window that's too loose will let external noise and air in and your energy bills can increase. Neither scenario is ideal, but both could be fixed with the proper tools and perseverance.
Paint can build up on the channels of the old weighted sash window tracks, which can cause them to jam. The majority of these issues can be resolved by cleaning and oiling the tracks.
Remove the caulking that was used in 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 to make use of a sharp blade and then put up sheets of plastic and a vacuum cleaner right below to contain any paint dust and chips.
Then, clean the tracks with a dry cloth and apply a silicone lubricant to ensure better glide. You can purchase this at many home improvement stores or on the internet. Then, you can move the sash up or down to test it.
If it is still jamming it could be a problem with the sash cord. Examine the sash cord to determine if the cord is caught or hanging in the sash, or if it has snapped off completely. If this is the case, you'll have to replace the window's cord.
A pin that keeps the rail in place may have fallen out. It can be difficult to repair, and you'll have to contact an expert in the majority of instances.
If a pin isn't falling out but the wood has gotten warped or swollen, it's a good idea to use a wood hardener on it. The liquid is quick drying and can help restore damaged wood. It's not necessary to take out your sash windows to repair them. After you've used it you'll be able to remove the two sashes by placing a block of wood on the top of the corner where they meet and tapping it lightly using an tool.
Draughts
Draughts can be a concern when you have an old sash window, especially during the winter. They can be caused by decayed wood, cracked putty, or worn cords for sash. This causes cold air to seep around the window, making it difficult to heat your home. You can reduce the risk of drafts by filling the gaps with expanding foam, or by using draught-proof strips that are available at most hardware shops. They are efficient, but they will need to replace them periodically as the foam expands with use.
A alternative that is more durable is Gapseal, a sponge-like seal that you can cut to size and insert into the gaps between your sash window frame. It can be applied on its own or with adhesive strips on the bottom and top of the frame. This is a bit costly and must be reapplied over the duration of your window's life, but it can provide a long-term solution and is easy to remove in the event that you want to open the window.
Cling film can also be used to block drafts. Simply roll it up and then insert it into all the gaps around your window. This is a great way to stop draughts however it could also hinder the movement of the sash and possibly cause fire. In addition the sash needs to be removed to re-open the door and the cling film will need to be applied each time you close the sash.
An alternative that is less expensive is to have your window sash professionally draughtproofed as part of a complete refurbishment service. This could include the installation of new sash strings staff beads and parting beads in addition to the lubrication and rebalancing the weights and the fluidization and rebalancing of the pulley wheel. It could also involve staining or painting the frames and sashes. This could bring the sash back to its original function and improve its energy efficiency and fix any minor defects in the wood. It is less disruptive than removing windows and will reduce drafts, enhance the thermal performance, and drastically reduce costs.
Decay
The good news is that windows' sash frames aren't beyond repair if they have been damaged or degraded. The timber used to construct the frames of these windows is usually of very high-quality and with proper restoration they can be revived to provide a high level of performance for many years. Regular inspections are essential and so is making sure the wood is properly ventilated. This will stop the accumulation of moisture that can cause wood decay.
Most of the problems that you'll encounter with sash windows will be readily apparent on close visual inspection, but some are harder to spot. In particular, wood decay is a difficult problem to address because fungus consumes the wood. While it is possible repair wood that is rotten but the best way to avoid future rot is by keeping the timber dry.
First, take off any paint from the hardware. It is possible to remove the bottom rail from the frame and also the meeting rail (this will depend on the position of the sash). The "pocket covers", which are small pieces of wood on the frame's side that permit access to the weights, must be removed. These are often nailed in place and stuck with paint, so you will likely require a knife to get them loose. Once the pockets are removed, you can begin chiseling out any wood rot and apply an excellent water-resistant filler. here After 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 shouldn't be displaced, or pulling one side more than the other. If they're not balanced, the sash can slide off its track and cause damage to the frame. You can replace the sashweights with new ones, or put in a new balancing system to stop the sash from swinging in the wrong way.
Poor Security
Sash windows are susceptible to wear and damage due to weather conditions over time. This can cause decay of timber, and requires replacement. Water marks under the window or a frame that is soft can indicate wood decay. A professional consultation is required to determine the condition and recommend any required repair work to the sash window.
As time passes, the bottom rails may also be damaged. Sills that have water marks, or a window that is soft to the touch may be a sign of this. A professional will be needed to evaluate the situation and recommend any needed replacement of the sash window's seal or replacement.
Triple and double glazed Sash windows do an incredible job of keeping noise pollution out of the home, so it can be a real cause for worry when they begin to let it back in. If this occurs, the structural integrity may be at risk and the sash window will require replacement.
A common issue with repairing sashes is when the sash gets stuck in the frame. This can be caused by an sash cord that has snapped or an indication of a problem with the sash's the ratchets. If the issue is with the sash's ratchets, a little gentle persuasion will usually work.
Removing the sash from the frame and removing the tracks of any dirt or dust will often aid in resolving this issue. After cleaning the tracks, take off any security fittings and carefully remove the chains or cords that hold the sash. A draught seal could be put on the staff bead to reduce draughts and enhance the appearance of the paint finish. The gap between the box and sash could be filled with decorators caulk to improve the operation of the sash and decrease the risk of draughts.
