20 Trailblazers Leading The Way In Window Sash Repairs
Window Sash Repairs
The majority of homeowners don't think too much about window sashes -- so long as they are able to are closed, open, and keep the outside air out and the air inside in. Over time, window sashes can become worn out and lead to air leaks, drafts or even sashes to become stuck.

Sash Weights
If your windows aren't closing and opening smoothly, or are stuck the way they should, a defective counterbalancing system could be at fault. This can occur due to a missing or damaged sash chain or cord, an unattached or misaligned sash weight, or a broken pulley.

The sash weights are tiny boxes made of cast iron that serve to support the sash as well as balance the window's counter-weight system. They are located in the bottom rails of every window frame, and are covered by a wooden access panel that can be cut open to reveal their location. The panels can also be removed to gain access to the weight pockets in the sash to clean, repair or replacement.
If you've been using sash windows for a long time you likely have an issue with the weights on the sash that cause them to lean or catch. The weights can be too heavy (they should be a bit heavier than the top sash), or installed in a way that isn't correct.
To fix this problem take out the stops (the trim that runs along the inside edge of the window at the point that it joins the frame to keep it in place). Put them away. This will require you to be gentle in order to not damage the profile of your meeting rails. You can then use a hammer to separate the stiles and rails, and then inspect them for damage.
After examining the stiles and rails of the sash, place some dust sheets on the floor and start working. Begin by removing the wood pegs from the mortise and tenon joints using a pin punch and a screwdriver or hammer. After removing the pegs, you can begin disassembling the sash. Remove the sash stop moldings as well as any sash cords that are still in place.
The next step is to weigh the sash in order to determine the amount of weight it will require for functioning. You can purchase vintage replacement sashweights online or in a few home improvement stores. Make sure you get the correct size to avoid over or under-weighting the sash.
Sash Cords
The majority of sash window problems result from damaged or worn sash cords. The weights put constant pressure on the sash's cords and this could cause them to break over time. If the cords break, sashes won't be able to open and close easily. The problem could be caused by a number of things like excessive force, aging, lack of maintenance or accumulation of moisture. When new sash windows repair windows, it's important to replace the old cords with new ones that are constructed from materials that last and resist moisture.
Begin by removing the inner stop strips, the thin wood strips that hold the sashes in their place with a utility knife and a chisel. Pry the stops from the sashes with care, and be on the lookout for any broken or cracked ones. Once the stops are removed, you can access the sash weights through an access panel that is cut into the frame's bottom, or by opening the jamb, and then removing the cover for the weight pocket.
It may take a bit more work to reach the sash cords, but with the right tools and a bit of patience it is not difficult. Get rid of the old cords first by cutting them at knots, and then pulling them out. Take the sash off and set it aside. Remove the staff bead, the nail that keeps the sash in position. Install the nail about a foot in length into the hole. This will temporarily stop the sash from slipping away while you string the counterweights.
After reinstalling the upper sash then reattach the sash cords and ensure that the sashes are balanced and move smoothly. Then, install the lower sash and repeat the process, ensuring that the sashes are properly sitting and moving smoothly.
Reattach the sash cables after you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole on the sash. Repeat the procedure for each side of the sash until cords are replaced and the sashes are operating normal.
Air leaks and drafts
Over time, the materials that seal your sash window to the frame of your house begin to deteriorate. This causes drafts and energy losses. A thorough inspection will reveal the areas of concern and help you determine your window sash repairs options. Your comfort preferences and skill level influence whether you can self-manage window repairs to your sash or require professional input. The scope of work is also influenced by history of the property's condition and the structural integrity.
If cold air is coming through a drafty or drafty door or window, your furnace will need to work overtime to warm your home. This inefficiency can eat into your heating bills and compromises the efficiency of your home's HVAC system. Drafts can also impact the quality of air inside and disrupt indoor comfort by the infiltration of allergens, pollutants and humidity from outside.
A drafty window can be identified by the feeling of cold air rushing into an area, even though all windows and doors are closed. Other tell-tale signs include an increase in the temperature of your home near the window and condensation on the frame or sill.
Repairing drafty windows is a an easy task that will lower your energy bills and increase your comfort in the home. First, inspect the exterior of the window. Look for bare wood and areas where the old caulking has cracked, exposing the gaps to cold air.
Examine the interface of the sash with the frame. This includes the parting bead and the staff bead. Examine the condition of the weather stripping (felt strips or foam tape) at these locations to determine if it's still intact and functional. If not, it needs to be replaced.
Also, take note of the condition of glazing putty, a hard putty that keeps panes of glass in place. Examine for cracks and crumbling that could expose the sash's exterior to moisture. This can cause problems with mold and damage to the glass.
Apply a fresh layer of glazing putty on the outside of the window to fix the problem. Using a flat-blade screwdriver, push the glazing points into place to fix them. Then wrap a piece of foam and fabric around each point to create an insulation agent against cold air.
Aesthetics
Window sash repair can give older windows a new appearance for less than a complete window replacement. Particularly for homeowners with older homes, a complete replacement could be a huge project, and a substantial financial commitment. Restoring window sashes is a great way to restore the original beauty of a home and value.
It is crucial to be aware of the condition and wear of window sashes to avoid any major issues. If you're unsure whether your windows are in need of repair it's best to have them evaluated by an expert. A sash repair could be less expensive than replacing the entire window. It will also help you save money on energy costs.
First, lower the upper sash down to the bottom. This is usually simple and will allow you to see the "parting beads", which are a grooved part on the rails which keep the two sliding sashes separated. They can be removed using a blade from the small pry-bar or putty knife. They are typically put in place with nails and then painted, so be careful not to harm them or the sliding sash.
After removing the beads that separate, you'll need to take off the pocket covers. They are pieces of wood inside the frame, low down, that give access to the sash weights. They are usually fixed with nails - they may also be snagged with paint, so it is important be extra cautious. After the nails are removed you can move the sash up and down to ensure it moves smoothly.
If it doesn't, there may be problems with the counterweights or sash cords. After you've checked all these, you can fix them as required.
Wooden windows look beautiful and natural. They work well with modern or traditional interiors. The options for staining or painting are endless. However, wooden windows require regular maintenance to prevent damage and rot.
