Sash Window Repair

Sash windows can be out of balance or break. Pam scours the web for salvaged, wavy glass and keep an eye out for discarded, metal sash weights. She then searches for replacements in the form of nuts or washers to help balance her window.

Pam puts each pane in with a rope of glazing compound that she works into the rabbet groove, or pocket, that is around the opening. This prevents drafts and prevent costly heat loss.

Sticking Sashes

It's a nightmare when double-hung windows get stuck. They'll be difficult to see if they rattle in a storm. A window that is too loose could let in air and noise which could increase your energy costs. Both of these scenarios are not optimal, but they can be corrected with the right tools and persistence.

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


Start by removing the caulking between the window stop (the internal one) and the window frame. Then scrape off any paint that's built up. Make sure to use a sharp blade, and then set up plastic sheets and a vacuum cleaner directly below to contain any paint dust and chips.

Clean the tracks using a dry cloth, and apply a silicone lubricant to ensure better sliding. It is available in most 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 due to a problem with the sash cord. Verify if the cord is caught or hanging in the sash, or if it has snapped off completely. It is necessary to re-cord the window in the event of this.

A pin that keeps the rail in place might have been ripped out. This isn't easy to fix, and you'll need to contact an expert in the majority of instances.

If window repair near me hasn't fallen out but the wood has gotten warped or swollen, it's recommended to use a wood softener on it. This is a quick drying liquid that can aid in restoring damaged wood, which means you'll be able to fix your sash window without having to remove it completely. After using it, you can pry off the two sashes by placing a piece of wood in the lower corner of the window where they meet.

Draughts

Draughts can cause problems when you have an old sash window, especially during the winter. Most often, they are caused by decayed timbers or cracked putty, worn weights for sash or sash cords that aren't balanced which can let cold air seep into the window, making it difficult to keep your home warm. There are some things you can do to help prevent draughts in your windows that are sash, like filling any gaps with expanding foam or using draught excluder strips that you can purchase at many hardware stores. These can be effective, although they'll need to be replaced regularly as the foam expands and gets worn away with use.

Gapseal is a more permanent solution that is more permanent. It's a spongy, rubbly seal that can be cut and then push into the gaps between the sash window frames. It can be applied by itself or in conjunction with adhesive strips on the top and bottom of the frame. This option is expensive and you'll need to apply it several times throughout the life of your window. However, it's an effective long-term fix and easy to remove.

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 drawback is that it could stop sash movement completely and may be risky for fire. The sash has to be removed in order to reopen the window, and the clingfilm needs to be to be applied every time the sash is closed.

As part of a comprehensive overhaul it is possible to have your window draught-proofed. This could include the installation of new sash strings, staff beads and parting beads, the lubrication and rebalancing the weights and the fluidization and rebalancing of the pulley wheel. It may also involve painting or staining of the frames and sashes. This will restore the sash to its original function and improve its energy efficiency and correct any minor imperfections in the wood. It's less disruptive than replacing windows completely and will dramatically reduce draughts and improve your home's thermal efficiency.

Decay

The good news is that frames for sash windows aren't beyond repair if they have been damaged or decayed. The timber used to construct the frames of these windows is usually of high-quality and, with the right restoration, can be restored to offer an excellent level of performance for many years. The key is to conduct regular inspections and making sure that the wood is well ventilated to prevent moisture accumulation, which can cause wood decay.

The majority of problems with sash window are easily visible, but others are more difficult to spot. Wood decay is a challenge to repair, since the fungus consumes the wood. While it is possible repair rotten timber however the best method to prevent further rot is by keeping the wood dry.

The first thing to do is to strip any paint off the hardware. The bottom rail and the meeting rail might need to be removed from the frame (depending on the location of your sash). The next step is to take off the "pocket covers" which are bits of wood that are located on the sides of the frame lower down that provide access to the weights (the parting beads run down the middle of them). These are often nailed in place and stuck with paint, so you will likely need to use an instrument to break them loose. Once the pockets have been removed, you can begin chiseling out any wood rot and apply a high-quality water-resistant filler. Once the filler is dry the primer coat must be applied to stop further decay.

It is a smart idea to inspect inside the window the sashweights to make sure they are balanced. They shouldn't be displaced or pulled one side more than the other. The sash may be thrown off its track if it is not properly balanced. This could cause the frame to break or become damaged. The sash weights can be replaced with new ones or a new balance mechanism can be installed, which will stop the sashes from swinging to the wrong side of the window frame.

Poor Security

Over time, sash windows can become exposed to the elements and prone to deterioration from weather and general wear. This can lead to decay of timber, and requires replacement. Wood decay can be detected by water marks under the window or the frame becoming soft to touch. It is essential to speak with an expert to assess the situation and determine if any repairs to the window sash are needed.

Additionally, with time, the rails on the bottom can become damaged. Water marks on the sill, or a window that is soft to the touch can indicate this. A professional consultation will also be required to determine the situation and recommend any replacement or resealing of window sash components.

It is a major concern when triple or double glazed windows start to let noise pollution back into your home. If this happens the structural integrity of the window could be at risk and the sash windows will need to be replaced.

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

This problem can be resolved by taking the sash off and cleaning the tracks. After cleaning the tracks, remove any security fittings and carefully remove the sash cords or chains. A draught seal can then be placed around the staff bead in order to reduce draughts and enhance the appearance of the paint finish. Decorators caulk can be used to fill in the gap between the box of the sash and the sash. This will enhance the operation of the sash and also reduce the possibility of draughts.
