Window sash and case window repairs Repairs

Most homeowners don't give much thought to window sashes as long as they are able to open and close and keep the air inside and the air out. As time passes window sashes may get worn out and cause air leaks, drafts or even sashes to become stuck.

The artist uses the sash which is placed on an easel to work glazing points into the gap. He also scrapes off paint and applies an oil-based preservative to the frame.

Sash Weights

If your windows aren't opening and closing with ease or are sluggish, a faulty counterbalancing system could be the reason. This could be due to the sash being damaged or missing chain, a misaligned or unattached weight, or a damaged or cracked pulley.

The sash weights are tiny boxes made of cast iron, that support the sash and balance the window's counter-weight system. The sash weights are located on the bottom rails of every window frame. They are protected by wood panels which can be removed to reveal their position. The panels can also be removed to gain access to the pockets of sash weights for cleaning, repairs or replacement.

There may be an issue with the sashweights, if you've had your sash windows over a period of time. They could lean or catch. The weights could be too heavy (they should be a little heavier than the top sash) or installed incorrectly.

To resolve this issue take out the stops (the trim that runs along the inside edge of the window at the point that it meets the frame to keep it in place). Set them aside. This will require you to be careful so as to not damage the appearance of your 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 dust sheets and begin working on the sash itself. Begin by removing the wood pegs using a pin punch and a screwdriver or hammer from the mortise-and-tenon joints. Once the pegs are gone you can begin disassembling the sash by removing the sash stop moldings and removing the sash cord knots that are connected, and then taking the sash off itself.

The next step is to weigh the sash in order to determine the amount of weight it will require for functioning. You can find vintage weights for replacement on the internet or at a few home improvement stores, but ensure that you purchase the right size so as not to under or over weigh the timber sash windows.

Sash Cords

Most sash window issues stem from damaged or worn sash cords. Sash cords are under constant stress from the weights, which can cause them break over time, especially when they're not maintained correctly. The sashes won't open or close as easily if cords break. The issue could be caused due to excessive force, aging or lack of maintenance or the accumulation of moisture. During window sash repairs it is crucial to replace the old cords with new ones made of a material that will last and resist moisture.

Begin by removing the inner stop strips, the thin wood strips that hold the sashes into place, using a utility blade and a Chisel. Remove the stops off the sashes with care and be on the lookout for any cracked or broken ones. After removing the stops, you can get access to the weights on the sash by opening the jamb or taking out the weight pocket.

Accessing the sash cords requires a little more work however it's not too difficult with the right tools and perseverance. First, take off the old cords by cutting them close to their knots and pulling them free. Take the sash off and set it aside. When the sash is removed then pull it back down on the staff bead (the nail that keeps the sash from falling) and insert the nail, which is about one foot long into the hole for the staff bead. This will temporarily stop the sash from slipping away while you finish stringing the counterweights.

After installing the upper sash then reattach the sash cords and make sure the sashes are properly balanced and move smoothly. Then, reinstall the lower sash and repeat the process, making sure that the sashes are properly sitting and moving smoothly.

Reattach the sash cable after you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole in the sash. Repeat this procedure on each side of the sash, making sure that the sashes function normally again.

Air leaks and drafts

Over time, the materials that secure sash windows to your frame of your home deteriorate, resulting in drafts and energy loss. A thorough inspection will identify the trouble spots and help you determine your window sash repairs options. Your comfort level and level will determine whether you are able to manage your own repairs or require assistance from a professional for window sash repair. The status of the property in the past and structural integrity concerns also affect the scope of work required.

If cold air is getting through a drafty or drafty door or replacing window sashes, the furnace will have to work overtime to warm your home. This inefficiency can increase your heating bills, and can compromise the efficiency of your HVAC system. Additionally, drafts can disrupt your indoor comfort and reduce indoor air quality by forcing in outdoor pollutant, allergens, and humidity.

A common indication of a drafty window is the feeling of cold air in your room regardless of windows and doors being closed. Other telltale signs are changes in temperature near the window, as well as condensation around the sill or frame.

Fortunately, fixing drafty windows is a relatively easy task that can cut your energy bills and improve the comfort of your home. Start by inspecting the outside of the window. Check for wood that isn't bare and areas where the caulking is cracked, opening the air gap.

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

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

To resolve the problem, apply a layer of fresh glazing putty on the inside of your window. To secure the glazing points use a flat-bladed screwdriver to push them into the right position. Wrap a piece or fabric and foam around each point. This will act as an insulation against cold air.

Aesthetics

Window sash repairs can give old windows a fresh new look at a lower cost than a complete window replacement. Particularly for homeowners who have older homes, a complete replacement can be a large undertaking and a major cost. In many cases, fixing window sashes can restore the original appeal of a house and increase its value as well.

Monitoring the condition of windows sashes is essential to avoid major problems. If you're not sure if your windows are in need of repair, it's recommended to have them evaluated by an expert. The cost of a sash repair is typically lower than the expense to replace the entire window, and can save you money on energy bills as well.

The first step is to lower the upper sash towards the bottom - this is generally easy and will allow you to get an unobstructed view of the "parting beads" (these are the grooved bits in the rail that connects either side that keep the two sliding sashes from colliding). They can be removed using a blade from a small pry-bar or a putty-knife. They are typically put in place with nails and then painted, so you must be careful not to damage them or the sliding sash.

After removing the beads that separate, you'll need to take off the pocket covers. These are tiny pieces of wood which are fixed to the frame at the bottom. They permit access to the sashweights. After the nails are removed you can move the sash upwards and downwards in order to make sure it moves in a smooth manner.

If it does not, there could be an issue with the counterweights or sash cords. After you've inspected them all, you can fix them if necessary.

Wooden windows have a natural beauty that blends in with both modern and traditional style interiors. The options for staining or painting are endless. Wooden windows require regular maintenance in order to keep them from rotting and damage.
