Sash Window Repair

Sash windows may become out of balance or break. Pam browses the internet for salvaged wavy glasses, and keeps an eye open for discarded sashweights made of metal. She then looks for replacements, such as washers or nuts, to ensure that her window is balanced.

Pam will bed each pane by placing an edging rope into the rabbet groove or pocket around the opening. This reduces drafts and expensive heat loss.

Sashes that stick Sashes

It's a nightmare when your double-hung windows get stuck. They'll rattle in the event of a storm and you'll lose view. A window that's too loose can let air and noise in, which will increase your energy costs. Neither scenario is optimal, but both can be addressed with the right tools and a little perseverance.

One of the most common issues with windows with weighted sash is that paint could build up in the channels that they slide over, causing them blockage. Fortunately, most issues related to this can be solved 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 to use a sharp blade, and set up plastic sheets and a vacuum cleaner directly below to contain any paint dust and chips.

Then, clean the tracks using a dry cloth, and apply a silicone-based lubricant for more smooth gliding. This lubricant is sold at many home improvement stores or on the internet. Then, you can move the sash up or down to test it.

If it continues to stop, the sash cable may be faulty. Examine the sash cord to determine if the cord is caught or hanging in the sash, or has snapped off completely. If this is the situation, you'll need to reconnect the window.

A pin that keeps the rail in place could have been ripped out. It can be difficult to fix and you'll require the help of an expert most of the time.

If a pin isn't falling out, but the wood has gotten swollen or warped, it's a good idea to use a wood hardener on it. The liquid is quick drying and can restore 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 wood on the bottom corner of the window where they meet.

Draughts

Draughts can be a major issue for old sash windows particularly in winter months. Most often, they are caused by decayed timbers, cracked putty, worn weights for sash or sash cords that aren't balanced which can allow cold air to get in around the window and make it difficult to keep your home warm. There are some things you can do to stop draughts from coming through your windows with sash, for example, filling any gaps with expanding foam or strips to prevent draughts. These can purchase at many hardware stores. These are efficient, but they'll have to be replaced periodically because the foam expands and gets worn away with wear and use.

Gapseal is a longer-lasting solution. It's a spongy, rubbbery seal you can cut and push into the gaps between the sash window frames. It can be used by itself or with adhesive strips at the top and bottom. This option is expensive and you'll need to apply it again throughout the life of your window. However, it's an effective long-term fix and easy to remove.

Cling film can also be used to stop draughts. Simply scrunch it and then insert it into the gaps that surround your window. This is a great way to stop draughts however, it could also block the sash's movement and possibly cause fire. In addition the sash will have to be removed to re-open the window and the cling film has to be applied every time you close the sash.

As part of a complete refurbishment, you can have your window draught-proofed. This can include the installation of new sash strings, staff beads and parting beads as well as the lubrication and rebalancing of the weights, fluidization and rebalancing of the pulley wheel. It may also involve painting or staining of the frames and the sashes. This could bring the sash back to its original function and improve its energy efficiency and correct any minor defects in the wood. It is much less disruptive than replacing windows entirely and can significantly reduce draughts and improve your home's thermal efficiency.

Decay

The good news is that your windows' sash frames aren't in need of repair if they've been damaged or deteriorated. The frames of these windows are generally made of high-quality timber. With the right restoration they can be rehabilitated to provide high performance for many more years. The key is to conduct regular inspections and making sure that the wood is properly ventilated to avoid moisture accumulation which can lead to wood decay.

Most of the problems you'll encounter with sash windows are evident upon close inspection, but some are more difficult to detect. Wood decay is difficult to fix, as fungus eats the wood. Although it is possible to repair rotten timber, the best way to avoid further rot is by keeping the wood dry.

The first step is to remove any paint off the hardware. The bottom rail and the meeting rail may require removal from the frame (depending on the location of your sash). You will then need to take off the "pocket covers" that are pieces of wood that are located on the sides of the frame lower down that give access to the weights (the partsing beads run along the middle of them). These are often fixed by nailing them in place and then securing them with paint, so you will likely require a knife to get them out of the way. Once the pockets have been removed, you can begin chiseling out any wood rot and apply an excellent, water-resistant filler. After the wood filler has dried the primer coat must be applied to stop further decay.

It is a good idea to examine inside the window for weights of the sash to ensure that they are balanced. They shouldn't be in the wrong alignment, or pulling one side harder than the other. If they aren't 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 install an entirely new balance system to stop the sash from swinging in the wrong direction.

Poor Security

As time passes sash windows become exposed to the elements and susceptible to deterioration from weather and general wear. This can cause decay of timber, which will require replacement. Wood decay can be detected by water marks under the window or by the frame becoming soft to touch. It is essential to speak with an expert to assess the situation, and determine if any sash window repairs are necessary.

Similarly, over time the rails at the bottom may become damaged. This is evident by the presence of water marks on the sill or by the window becoming soft to touch. A professional will be required to assess the situation, and recommend any necessary replacement of the sash window's seal or replacement.

Double and triple-glazed Sash windows do a fantastic job of keeping noise pollution out of your home, but it can be a cause for worry if they begin to let it in. If this occurs the structural integrity of the window could be at stake and the sash window will require replacement.

A common issue with repairing sashes is when the sash gets stuck in the frame. It could be due to a snapped cord or problems with sash rattles. If it's the latter, then a bit of gentle pressure can help the window to open to reopen. Alternatively, the ratchets need to be reset.

Removal of the sash from the frame and cleaning the tracks of any dust or dirt can often assist in resolving this issue. Once the tracks are clean remove any security fittings that might be present, and then removal of the sash cords as well as chains will allow the sash to be removed. The staff bead may be sealed with a draught-proof seal to reduce the possibility of draughts. This will also improve the finish of paint. Decorators caulk can be used to fill the gap between the sash's sash box and the sash. This will improve the sash's operation and reduce the risk of draughts.
