Sash Window Repair

Sash windows can get out of balance and break. Pam searches the internet for salvaged Wavy glass, wavy glass, and keeps an eye out for the sash weights that are discarded, made of metal. She then hunts for replacements in the form of nuts or washers to help balance her window.

Pam covers each pan with a rope of glazing compound she works into the rabbet groove, also known as a pocket, around the opening. This prevents drafts and costly heat loss.

Sticking Sashes

When your double-hung window gets stuck in the middle, it's a nightmare. They'll shake in the event of storms and you'll lose view. On the other side, a upvc window repair that's too loose can let outside air and noise in and your energy costs can increase. Neither scenario is ideal, but both could be solved with the proper tools and perseverance.

Paint can build up on the channels of old weighted sash window tracks, which can cause them to block. Fortunately, most issues related to this can be resolved by cleaning and lubricating the tracks.

Take the caulking off of the space between the window stop (the one on the inside) and the frame of the window. Scrape away any paint that's built up. Make sure you employ a sharp blade and then put up sheets of plastic and a vacuum cleaner right below to keep any paint dust and chips.

Then, wipe the tracks with a dry cloth and apply a silicone-based lubricant for more smooth glide. This lubricant is sold in a majority of home improvement stores or on the internet. Then move the sash up or down to test it.

If it continues to jam it could be faulty. Check to see if the cord is caught or hanging in the sash or snapped. If this is the situation, you'll need to re-cord the window.

Another reason for an obstruction is that a pin that holds the meeting rail in place has slipped away. It can be difficult to fix and you'll have to call a professional most times.

If a pin isn't falling out but the wood has become swollen or warped, it's a good idea to apply a wood hardener to it. This is a quick drying liquid that can aid in restoring damaged wood, and you'll be able repair your window sash without having to take it off completely. After you've used it you should be able to remove the two sashes by placing a piece of wood on the top of the corner where they meet, and tapping it lightly using the tool.

Draughts

Draughts can be a concern when you have an old sash window particularly in winter. They can be caused by rotten wood, cracked putty, or worn cords for sash. This allows cold air to seep around the upvc window repairs, making it difficult to heat your home. There are several ways to stop draughts from coming through your sash windows, such as filling any gaps with foam that expands or strips to block draughts that you can buy at most hardware stores. They're effective however, you will require replacing them regularly as the foam expands with use.

Gapseal is a stronger solution. It's a spongy, rubbly seal that can be cut and then push into the gaps between the window frames of the sash. It can be applied on its own or with adhesive strips placed on the top and bottom of the frame. This is a bit costly and will need to be applied over the duration of your window's lifespan, but it is an option for the long term and is easy to take off if you want to open the window.

Another popular DIY method of draughtproofing is to use cling film that is scrunched up and pushed into all the gaps around your window. This is an effective draught stopper but the downside is that it could stop sash movement completely and pose a fire hazard. Additionally the sash needs to be removed for you to open the window again and the cling film needs to be applied each time you close the sash.

A better option is to have your sash windows professionally draught proofed as part of a complete refurbishment service. This could include the replacement of sash cords, staff beads, parting beads, lubrication for the pulley wheels and rebalancing of the weights, in addition to staining or painting the frames and sashes. This could restore the sash to its original function, improve its energy efficiency and correct any minor defects in the timber. It is less disruptive than taking out the windows, and can reduce draughts, increase the thermal performance, and drastically reduce the cost.

Decay

If your windows with sash have suffered decay or damage, the good news is that they aren't necessarily damaged beyond repair. The frames of these windows are usually constructed of high-quality wood. With the right restoration they can be repaired to give you the best performance for a long time. Regular inspections are crucial in ensuring that the wood is properly ventilated. This will help prevent the build-up of moisture that could lead to wood decay.

The majority of issues that arise that arise from sash windows are readily visible, but others are more difficult to detect. Particularly, decay of wood is a very difficult problem to address because fungus consumes the wood. It is possible to repair rotten sections of timber, but the best way to prevent future rot is to make sure the timber is dry.

The first thing to do is to strip any paint from the hardware. The bottom rail and the connecting rail might have to be removed from the frame (depending on the position of your sash). The "pocket covers", which are small pieces of wood that are placed on the frame's side, which allow access to the weights, should be removed. These are often put in place by nails and then covered with paint, so you will likely need to use a knife to get them off. Once the pockets have been removed, you can start cutting out any wood rot and apply an extremely high-quality water-resistant filler. Once the filler is dry, a primer coat should be applied to prevent further decay.

It is a smart idea to examine inside the window the sashweights to make sure they are balanced. They shouldn't be displaced, or pulling one side harder than the other. If they aren't balanced, the sash could drop off its track and could cause damage to the frame. The sash weights can be replaced with new ones or a new mechanism for balancing can be fitted to stop the sashes from swinging towards the wrong side of the frame.

Poor Security

Over time sash windows become exposed to the elements and susceptible to deterioration from weather and general wear. Over time, this can cause wood decay, which in turn will need to be replaced, an expensive repair that has to be addressed as quickly as is possible. Water marks on the window or on a softened frame can indicate wood decay. A professional consultation is required to evaluate the situation and recommend any needed sash window repair work.

Over time the rails at the bottom can also be damaged. This is evident by the presence of water marks on the sill or the window becoming soft. A professional is required to evaluate the situation and recommend any needed repair of sash windows or replacement.

It can be a real concern when triple or double windows are glazed and start to allow noise pollution back into the home. If this happens the structural integrity could be at risk and the sash window may require replacement.

One common sash window repair problem is that the sash becomes stuck in the frame. This can be due to the sash cord being snapped or an indication of an issue with the sash or ratchets. If the problem is with the sash ratchets, a little gentle persuasion will usually work.

The sash should be removed from the frame and clearing the tracks of dirt or dust can 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 can then be applied around the staff bead in order to reduce draughts and improve the appearance of the paint finish. The gap between the box and sash can then be filled with decorators caulk in order to improve sash operation and reduce the risk of draughts.
