Sash Window Repair

Sash windows may become out of balance or even break. Pam is on the lookout on the internet for salvaged wavy glasses, and keep an eye out for discarded metal sashweights. She then seeks replacements in the form of washers or nuts to help balance her window.

Pam will bed each pane 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-hung window becomes stuck, it's a nightmare. They'll be difficult to see when they squeak in a storm. On the other side, a window that's too loose can let outside noise and air in and your energy costs could increase. Both of these scenarios aren't ideal however they can be rectified by using the appropriate tools and persistence.

A common issue with old weighted sash windows is that paint may accumulate in the channels that they slide on, causing them jam. Most of these problems can be solved by cleaning and oiling the tracks.

Begin by removing the old caulking that was between the window stop (the interior one) and the window frame. Then scrape away any accumulated paint. Make sure to make use of a sharp blade and then set up sheets of plastic and a vacuum cleaner directly below to catch any paint dust and chips.

Clean the tracks with a dry cloth and apply a silicone-based lubricant for more smooth gliding. This lubricant is sold in a majority of home improvement stores or on the internet. You can test it by moving the sash upwards or downwards.

If it continues to stop it could be faulty. Verify if the cord is catching or hanging from the sash, or if it has snapped off completely. If this is the case, you'll have to re-cord the window.


Another possible cause of a jam is that a pin that holds the meeting rail in place has slipped away. This isn't easy to repair, and you'll have to call an expert in most instances.

If a pin isn't falling out, but the wood has gotten swollen or warped, it's a good idea to apply a wood hardener to it. what do you think is quick drying and can repair damaged wood. You won't have to remove the windows on your sash to repair them. After using it, you'll be able pry the two sashes apart by placing a block of wood on the top of the corner where they meet, and tapping it lightly with the tool.

Draughts

Draughts can be a concern with sash windows that are old, especially during the winter. They are usually caused by decaying wood, cracked putty, or worn sash cords. This causes cold air to get inside the window, making it more difficult to heat your home. There are some options you can take to stop draughts from coming through your windows with sash, for example, filling any gaps with expanding foam or draught excluder strips that you can purchase from most hardware stores. They are efficient, but they will require replacing them regularly as the foam expands over time with use.

A alternative that is more durable is Gapseal, a spongy rubbbery seal that you cut to the desired size and then put into the gaps between your sash window frame. It can be used alone or in conjunction with adhesive strips at the top and bottom. This option is fairly expensive and must be reapplied over the time of your windows' life, but it can provide an option for the long term and is simple to remove if you want to open the window.

Cling film can also be used to block drafts. Simply roll it up and then push it into the gaps surrounding your window. This is a great draught-stopper however, it could also hinder the movement of the sash and even cause a fire. In addition the sash needs to be removed to re-open the door and the cling film will need to be applied every time you close the sash.

A better option is to have your sash windows professionally draught proofed as part of a general refurbishment service. This could include the installation of new sash strings, parting beads and staff beads, the lubrication and rebalancing the weights and the oiling and rebalancing of the pulley wheel. It could also involve staining or painting of the frames and sashes. This can aid in restoring the function of the sash and increase its energy efficiency, in addition to fixing any minor wood defects. It's less disruptive than replacing the windows completely and will dramatically reduce drafts and enhance your home's thermal efficiency.

Decay

The good thing is that your sash window frames are not damaged beyond repair even if they have been damaged or degraded. The frames of these windows are typically constructed from high-quality timber. With the proper restoration they can be rehabilitated to give you the best performance for many more years. Regular inspections are essential, as is ensuring the wood is properly ventilated. This will stop moisture build-up that can cause wood decay.

Most of the problems you will face with sash windows are easily visible on a close inspection, but some are more difficult to detect. Particularly, decay of wood is a difficult issue to address because fungus eats away at the wood. It is possible to repair rotten sections of timber, however, the best method to stop further decay is to ensure that the timber is kept dry.

First, clean what do you think from the hardware. The bottom rail and the connecting rail might require removal from the frame (depending on the position of your sash). The "pocket covers" are tiny pieces of wood placed on the frame's side that permit access to the weights, should be removed. These can sometimes be fixed by nailing them in place and then securing them with paint, so you'll likely require a knife to cut them off. After the pockets have been removed, you can start chiseling out any wood rot and apply an excellent, water-resistant filler. Once the filler has dried a coat of primer should be applied to protect against further decay.

It is an excellent idea to examine the sash's weights inside the window too, to ensure that they are in balance and not pulling one side more than the other. If they're not balanced, the sash is liable to drop off its track and break or damage the frame. You can replace the sashweights with new ones, or put in an updated balancing system to prevent the sash from swinging in the wrong direction.

Poor Security

Sash windows are vulnerable to damage and wear due to weather conditions over time. This can cause decay of timber, which requires replacement. Water marks on the window or a softened frame can indicate wood decay. A professional consultation is required to determine the condition and recommend any required sash window repair work.

Similarly, over time the rails on the bottom can become damaged. This is evident by the presence of water marks on the sill, or the window becoming soft to touch. A professional consultation will also be required to determine the situation and recommend any needed resealing or replacement of sash window components.

It can be a real concern when triple or double glazed windows start to let noise pollution back into your home. If this happens the structural integrity of the sash windows may be at risk, and they will likely need to be replaced with an alternative option.

A common window repair issue for sash windows is that the sash becomes stuck in the frame. It could be due to a snapped sash cord or it could be an indication of a problem with the sash ratchets. If the problem is with the sash's ratchets, a little gentle persuasion will usually work.

This issue can be solved by taking the sash off and cleaning the tracks. After cleaning the tracks, remove any security fittings and carefully remove the chains or cords that hold the sash. The staff bead may be sealed with an draught-proof seal in order to minimize the possibility of draughts. This can also improve the finish of the paint. The gap between the box and sash can then be filled with decorators caulk to enhance sash operation and reduce draughts.
