Sash Window Repairs
If sash windows don't receive regular maintenance, they may become ineffective. This can cause drafts as well as energy loss and moisture damage.
Paint can peel and crack, leaving the timber exposed to the elements. Specialized joiners can repaint the wood or re-stain it, repairing any damage.
An easel can be an excellent tool to work on sash windows since it gives you a stable base to work from. A reliable scraper is important.
Sash Cords that are Broken or Worn
Over time, sash cables may become brittle. They may snap or break. This is often due to a underlying problem with the window itself or broken pulleys, however it could also happen when the sash is opened and closed repeatedly. The sash could be difficult to move without requiring a lot of effort or sagging.
To repair broken cords of sash, first you need to open the window and locate the parting beads, a thin piece of wood that divides the upper and lower sashes. Gently pry the bead away from the frame using the screwdriver. After removing the bead you can begin to remove the sash. After the sash has been completely removed, you will have to find the two cast iron weights housed in a pocket located on either side of the sash. Typically, one is located in the back (towards exterior side of window frame) and another in the front (towards the interior side of the frame). Remove both of them from their pockets and put them aside.
After taking the counterweights out of the sash channels, you can remove the access panel. Depending on the kind of window you have there may be screws or a chisel to assist you in removing this panel. After the panel is removed, you will be able to see the coiled spring that helps retract the sash cords. If it's not functioning properly, you'll hear the window trying to move or feel a slight resistance.
To correct this issue fix, you'll need re-coil the spring. Once it's re-coil you can tie it with the help of a cord. This is very important since a loose knot could cause the cords to detach and not retract when needed.
After the cords have been tied, you can replace access panels as well as the jambliner. Slide the sash onto the wall. Check that the new cords are both long enough and securely tied. After that, you can re-insert the sash cords in the slots and holes on the sides of the lower sash. You can then place the counterweights back into their pockets. Now you can test your work. Move the sash up and down to make sure it moves smoothly.
Air and drafts Leaks
Sash windows can develop drafts and air leaks as a result of age, damage to the window or just poor construction. These issues can be a sign that windows are ready to be replaced. However they can be fixed with a bit of effort.
One of the most prevalent draft and air leak issues is caused by weather stripping that is worn or the absence of any weather stripping in any way. Foam tape or a similar product is recommended to close the gaps between the sash and the frame. This helps seal the gap and keeps hot or cold air out. If the weather stripping is missing, damaged or folded over, it can result in drafts and a loss of energy efficiency.
It's important to remember that if the wood on your window is starting to decay, you'll probably need to replace it entirely. However, it's not always the situation. Your Tasker may be capable of saving the timber by making a few careful repairs. Typically, the best way to tell if your sash windows are decaying is to push a screwdriver through the timber and then observing if it is able to go all the way through.
An easy fix is to replace the pockets covers and bead. This can be accomplished by cutting the paint between the sash and frame with the help of a utility knife, then cutting the pocket cover or the parting bead off using a chisel or a scraper. It's easy to replace the beading because it is available in similar styles.

However, most Taskers are able to get these types of jobs completed in a few hours, or even less.
Rotting Wood

Repairing windows made of wood that are rotting is an effective solution however replacing them generally the best option. To prevent the decay of your sash window, you should inspect them on a regular basis for signs that moisture is getting in.

Additionally, you should use a dehumidifier to control the humidity levels, since excessive humidity can cause wood to expand and stick. You can also use a thin layer of wax on windows and sashes in order to lubricate them.
If a sash becomes stuck, the first step is to check the counterweights for any imbalance. If the counterweights are in good condition and there is no evidence of imbalance, the issue could be due to a draft or air leak. If this is the situation, you can close the draft using foam tape or rope caulk.
Wood filler can be used to repair a window that has minimal decay. To ensure a seamless finish make sure you choose a filler that matches the color and type of your wood. Once the filler has dried and is smooth, sand it before painting. If you notice that a piece of your sash is totally decayed, replacing it with new wood will be the best option.
The removal of old wooden windows with weighted-sash isn't easy, but it's important to preserve as much of the original frame as is possible to cut down on costs for labor and prevent unnecessary damage. Before starting, take a photo of the window as it's put together to serve as a reference for the disassembly procedure. You can also build an easel using framing the wood to be able to work upright, while obtaining the ideal angles for glazing and scraping. A good scraper such as the Bahco can make this job much easier by allowing you to adjust the blades to create the right angle for curved areas of the sash.
Damaged Frame
As windows age, their frames may become damaged and begin to rot. The good news is that it's usually possible to repair these wooden frames rather than replacing them. This is a large project that requires lots of materials.

Earlier sashes were joined together with tapered wooden pegs which were driven through a mortise tenon. This type of joint is more difficult to remove and will require a hand saw, a knife or a pick to cut through the glueline. Sashes made later used glue, which is much easier to separate.
Once the sash is repaired then it's time to install the track made of vinyl in the frame. Remove the pawls of each locking terminal using a screwdriver, and then lower the sash so that it rests on jamb liners made of vinyl.
It's important to apply glazing putty prior to reinstalling your sash. This is a mix of chalk and linseed oil, and you can buy it at any hardware store. Make sure you have a few extra pieces of chalk on hand to keep the putty workable and help you clean up. Once you've mixed the putty, work it until it's smooth.
