A Step-By-Step Guide To Sash Window Repair
Sash Window Repair
Sash windows can go out of balance and even break. Pam scours the web for salvaged, wavy glass and keeps an eye out for scraps of sash weights made of metal. She then seeks replacements in the form of nuts or washers to ensure that her upvc window repair is balanced.
Pam will set each pan by placing the glazing material in a rope into the rabbet groove or pocket around the opening. This helps cut drafts and costly heat loss.
Sticking Sashes
When your double-hung upvc window repairs gets stuck and shatters, it's a nightmare. They'll shake during an icy storm and you'll lose your view. On the other the other hand, windows that are too loose can let outside noise and air in and your energy costs may increase. Neither scenario is ideal, but both could be solved with the proper tools and perseverance.
Paint can accumulate on the channels of the old weighted sash window tracks, causing them to become jammed. Fortunately, the majority of issues with this can be solved through cleaning and lubricating the tracks.
Start by removing the caulking that was between the window stop (the one inside) and the window frame. Scrape off any paint that has accumulated. Be sure to make use of a sharp blade and then put up plastic sheets and a vacuum cleaner directly below to catch any paint dust and chips.
Clean the tracks using a dry cloth, and apply a silicone lubricant for more smooth gliding. You can find this at many home improvement stores or online. Then, move the sash upwards or down to test it.
If it continues to jam it could be due to an issue with the sash cord. Verify whether the cord is stuck or hanging from the sash, or if it's snapped. If this is the case, you'll have to reconnect the window.
A pin that holds the rail in place may have lost its grip. It can be difficult to repair, and you'll have to consult an expert in the majority of instances.
You can use a wood softener if the wood is swollen and warped, but there's not a pin. This liquid will dry quickly and can repair damaged wood. It's not necessary to remove your sash windows in order to repair them. After using it, you can take off the two sashes by placing a piece of wood in the lower corner of the upvc window repair where they meet.
Draughts
Draughts can be a major issue for old sash windows particularly during winter months. They can be caused by rotten wood, cracked putty, or worn cords for sash. This can allow cold air to get inside the window, making it more difficult to warm your home. You can prevent drafts by filling the gaps with expanding foam, or using draught-excluding strips found in many hardware stores. These can be effective, although they will need to be replaced periodically because the foam expands and gets worn away with time.
A more permanent option is Gapseal, a rubbery spongy seal that you can cut to size and put into the gaps between the window frames of your sash. It can be used by itself or with adhesive strips at the top and bottom. This option is fairly expensive and will need to be applied over the duration of your window's lifespan, but it is a long-term solution and is easy to remove when you wish to open the window.
Another popular DIY method of draughtproofing is to use cling wrap that is rolled up and placed into the gaps around your window. This is an effective draught blocker, but the drawback is that it can hinder sash movement completely and may be an hazard to fire. Additionally the sash will have to be removed to re-open the door and the cling film has to be applied every 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 replacement of sash cords, parting beads, staff beads, lubrication of pulley wheels and rebalancing the weights, and staining or painting the frames and sashes. This could restore the sash to its original function and increase its energy efficiency and fix any minor flaws in the timber. It is less disruptive than taking out the windows, and can reduce drafts, enhance thermal performance and significantly reduce the cost.
Decay
If your sash windows have suffered from decay or damage, the good news is that they aren't necessarily damaged beyond repair. The frames of these windows are typically constructed of high-quality wood. With the proper restoration they can be repaired to give you the best performance for a long time. Regular inspections are key and so is making sure the wood is adequately ventilated. This will prevent moisture build-up that can cause wood decay.
The majority of issues that arise that arise from sash windows are readily visible, but others are more difficult to detect. Particularly, wood decay is a very difficult problem to treat because fungus eats away at the wood. It is possible to fix wood that is rotten, however, the best method to prevent future decay is to ensure the timber is kept dry.
The first step is to remove any paint off the hardware. The bottom rail and the meeting rail could have to be removed from the frame (depending on the position of your sash). You will then need to take off the "pocket covers" that are pieces of wood in the side of the frame low down that provide access to the weights (the partsing beads run along the middle of them). They can be nailed in place and stuck with paint, so you'll likely need to use a knife to cut them loose. Once the pockets are removed, you can start cutting out any wood rot and apply an excellent, water-resistant filler. After the filler has dried, it is recommended that a coat of primer be applied to protect against further decay.
It is a good idea to examine inside the window the sashweights to ensure they are balanced. They shouldn't be in the wrong alignment or pulled one side more strongly than the other. If they're not balanced, the sash could fall off its track and cause damage to the frame. The sash's weights can be replaced with new ones or a new balance mechanism can be installed that will stop the sashes from swinging towards the wrong side of the frame.
Poor Security
Sash windows are susceptible to wear and damage due to weather conditions over time. Over time, this can cause wood decay, which in turn will need to be replaced, a costly repair that needs to be addressed as soon as possible. Wood decay can be detected by water marks beneath the window, or the frame becoming soft to touch. It is crucial to speak with an expert to evaluate the situation and determine if any sash window repairs are necessary.
Additionally, with time, the rails at the bottom may become damaged. This can be spotted by the presence of water marks on the sill or the window becoming soft. A professional will be required to examine the situation and recommend any needed replacement of the sash window's seal or replacement.
It can be a real concern when double and triple windows are glazed and start to allow noise pollution back into the house. If this is happening the structural integrity of windows could be at risk, and they is likely to need to be replaced with an alternative option.
A typical sash repair issue is when the sash gets stuck in the frame. This can be caused by the cord snapping or a problem with sash ratchets. If the latter is the case scenario, a little gentle pressure can help the window to open again - or alternatively, the ratchets will need to be reset.
This issue can be solved by removing the sash and cleaning the tracks. After cleaning the tracks, take off any security fittings and carefully remove the chains or cords that hold the sash. The staff bead can be sealed using a draught-proof seal that will reduce the risk of draughts. This will also improve the finish of paint. The gap between the box and sash can be filled with decorators caulk in order to improve the operation of the sash and decrease draughts.
