Window Sash Repairs

Many homeowners don't care about window sashes -- so long as they are able to are closed, open, and keep the outside air out and the inside air in. But over time, they'll get worn out, causing drafts, air leaks, or even sticking sashes.

Sash Weights

If windows aren't opening and closing in a smooth manner or are sticking, a faulty counter-balancing system could be at fault. This can occur because of a broken or damaged chain/sash cord as well as a misaligned or unattached sash weight, or a broken pulley.

The sash weights are small boxes, typically made of cast iron that help support the sash and also help balance the counter-weight system of the window. They are located at the bottom of every window frame. They are covered with wood panels which can be removed to reveal their location. These panels can be removed to allow access to the sash-weight pockets to clean and repair or replace them.

If you've been using sash windows for a long time, it's likely that you have a problem with weights on the sash that cause them to sag or catch. The weights could be too heavy (they should be a little heavier than the top sash), or installed incorrectly.

To fix this problem, remove the stops (the trim that runs along the inside edge of the window where it joins with the frame to keep it in position). Place them aside. It is important to do this with care so as not to harm the appearance of the overlapping rails. Then, you can employ a hammer to break the stiles and rails and inspect them for damage.

After you've examined the stiles and rails, lay down a few dust sheets and start working on the sash itself. Start by taking the wood pegs out of the mortise and tenon joints using a pin punch and a hammer or screwdriver. Once the pegs are gone, you can begin to disassemble the sash by taking out the sash stop moldings as well as removing any sash cord knots in place, and finally, taking the sash off itself.

The next step is to weigh the sash in order to determine how much weight it will require for functioning. You can find vintage replacement sash weights online or at some home improvement stores, but be sure to purchase the right size so as not to overload or underweight the sash.

Sash Cords

Most sash window issues stem from broken or worn sash cords. The weights exert constant pressure on the sash's cords and this can cause them break over time. The sashes won't be able to open or close as easily when the cords break. The problem may be caused due to excessive force, aging or a lack of maintenance or the buildup of moisture. During window sash repairs it is crucial to replace the old cords with new ones that are constructed from materials that last and resist moisture.

Start by removing the internal stop strips, thin wood strips that hold the sashes into the frame with a utility knife and a chisel. Remove the stops off the sashes with care and keep an eye out for cracked or broken ones. After removing the stops, you can gain access to the sashweights by opening up the jamb or taking out the weight pocket.

Accessing the sash's cords requires a little more work but it's not a problem with the right tools and perseverance. Take the old cords out first by cutting them at their knots and then pulling them out. Then, remove the sash from the frame and put it aside. When the sash is removed then pull it back down on the staff bead (the nail that prevents the sash from falling) and insert one nail that is about 1 foot into the staff bead hole. This will temporarily stop the sash from falling while you string the counterweights.

After reinstalling the upper sash and sash cords, reconnect them and make sure the sashes are properly balanced and move smoothly. Reinstall the lower sash and repeat the process. Verify that the sashes have been properly set and are moving smoothly.

After you've installed counterweights, connect the sash window renovation cords by putting the sash cord through the pulleys and threading the other end of the cord through a knot hole in the sash to secure it into place. Repeat this process on both sides of the sash, making sure that the sashes work as intended again.

Air leaks and drafts

Over time, the materials that connect your sash window to the frame of your home deteriorate. This causes drafts and energy losses. A thorough inspection will identify the trouble spots and assist you in determining 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 assistance. The scope of work is also affected by the historical property status and the structural integrity.

If cold air enters through a sluggish window, your furnace has to work overtime to keep your house warm. This inefficiency can increase your heating costs and could compromise the efficiency of your HVAC system. Drafts can also affect the quality of indoor air and cause discomfort in the home by the infiltration of allergens, pollutants and humidity from outside.

A typical indication of a drafty window is the sensation of cold air in your room regardless of all windows and doors being shut. Other indicators to look out for are changes in temperature near the window, and condensation on the frame or sill.

Fortunately, fixing drafty windows is a relatively simple job that can lower your energy costs and enhance the indoor comfort. First, inspect the outside of the window. Examine for bare wood and areas where the caulking has cracked, exposing the gaps to cold air.

Examine the sash's interface with the frame including the parting beads and staff bead. Check the condition of the weather stripping (felt strips or foam tape) at these points to determine if they are intact and working. If not, it's going to need to be replaced.

Also, take note of the condition of glazing putty, which is a tough putty that keeps panes of glass in place. Examine for cracks or crumbling that expose the sash to moisture which could cause mold issues and even damage the glass of windows.

To fix the issue, apply a bed of fresh glazing putty to the inside of your window. To fix the glazing points, use a flat-bladed screwdriver to push them into position. Then wrap a piece foam and a piece of fabric around each point to create an insulation layer against cold air.

Aesthetics

A complete replacement of windows can be an expensive and time-consuming undertaking, particularly for older homes. Restoring window sashes is an excellent way to bring back the original beauty of a home and value.

Monitoring the condition of your window sashes is important to prevent major problems. It is best to consult an expert if not sure if your windows require repair. The cost of repairing a sash is usually less than the cost to replace the entire window, and it can help save your home energy costs in the process.

The first step is to lower the upper sash down to the bottom. This is generally simple and will allow you to observe the "parting beads" which are grooved bits on the rails that keep the two sliding sashes separated. These can be removed with the help of small pry-bars or a putty-knife. They are typically nailed into place and painted, so you must 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 tiny pieces of wood that are nailed into the frame at the bottom. They permit access to the sashweights. Once they are removed, the sash may be moved up and down to ensure that it moves in a smooth manner.

If it doesn't, it could be problems with the counterweights or sash cords. After you've checked all these, you can fix them if needed.
