Window Sash Repairs

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

With a sash propped up on an easel made from wood and a glass, the artist creates glazing points into a gap. He also scrapes paint off the frame and then applies a wood preserver.

Sash Weights

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

The sash weights are small boxes, usually constructed of cast iron that help support the sash and also help balance the counter-weight system of the window. They are found in the bottom rails of every window frame, covered by an access panel of wood which can be opened to reveal their position. These panels can be removed for access to the weight pockets in the sash to clean, repair or replacement.

There could be a problem with the sashweights if had your sash windows a while. They could be sagging or catch. This could be due to the weights being too heavy (they are supposed to be a little heavier than the top upvc sash windows near me) or due to them being installed incorrectly (some people have disabled their weight systems by cutting them off and removing the weights to save money or turning them in for scrap metal).

To address this issue, first take off the stops (the trim along the inside edges of the window where it meets the frame and keeps it in place) and then set them aside. You'll need to do this gently so as not to damage the appearance of the overlapping rails. Then, you can employ a mallet or hammer to break up the stiles from the rails and inspect them for damage or for any repairs that require to be made.

After you've checked the stiles and rails, lay down some dust sheets and then begin working on the sash itself. Start by removing wood pegs using a pin-punch and a screwdriver or hammer from the mortise-and-tenon joints. Once the pegs are gone then you can begin disassembling the sash by taking out the sash stop moldings, pulling off any sash cord knots attached and, finally, removing the sash itself.

Next you will want to weigh the sash in order to figure out how much weight is needed for its proper operation. You can find old weights for sash replacement online or in some home improvement stores, but ensure that you purchase the right size to ensure not to under or over weigh the sash.

Sash Cords

Most sash window issues stem from worn or broken sash cords. The weights put pressure on the sash cords which can cause them to break over time. The sashes will not open or close as easily if the cords break. The problem can be caused by a variety of things that can cause it, such as excessive force, aging, a lack of maintenance, and the accumulation of moisture. During window sash repairs it is essential to replace the old cords with new ones that are made from a material that will last and resist moisture.

Start by removing the internal stop strips, the thin wood strips that hold the sashes into their place with a utility knife and a Chisel. Remove the stops out of the sashes with care, and be on the lookout for any broken or cracked ones. After the stops have been removed, you can access the sash weights via an access panel cut into the frame's bottom, or by opening the jamb, and then removing the cover for the weight pocket.

Accessing the box sash windows cords takes some effort however it's not too difficult with the right tools and perseverance. First, remove the old cords by cutting them near their knots and then pulling them out. Then, remove the sash from the frame and put it aside. Pull down the staff bead, which is the nail that keeps the sash in place. Install the nail about a foot in length into the hole. This will keep the sash on its place while you finish stringing counterweights.

Reattach the sash strings after reinstalling upper sash window refurbishment. Verify that the sashes move smoothly and are balanced. Reinstall the lower double glazed sash windows for listed buildings, and repeat the process. Check that the sashes are properly set and are moving smoothly.

Reattach the sash cables once you have installed the counterweights. Thread the cord through the pulleys, and then through the knot hole in the sash. Repeat the process for each side of the sash until cords are replaced and the sashes function normally.

Air leaks and drafts

Over time, the materials that seal your sash window to the frame of your home deteriorate. This causes drafts and energy losses. A thorough inspection will reveal the trouble spots and help you decide on your window sash repairs options. Your preferences regarding comfort and ability level determine whether you are able to manage window repairs to your sash or require professional assistance. Historical property status and structural integrity concerns also influence the scope of work required.

If cold air is able to enter through a drafty window, your furnace is forced to perform overtime to keep your home warm. This inefficiency increases your heating costs and could affect the efficiency of your HVAC system. Drafts can also affect the quality of indoor air and affect indoor comfort by adding allergens, pollutant and humidity from outside.

A common indication of a drafty window is the sensation of cold air entering your room regardless of all windows and doors being closed. Other tell-tale signs include fluctuations in the temperature of your home near the window, and condensation on the frame or sill.

Fixing drafty windows is a simple task, which can reduce your energy costs and improve indoor comfort. Start by inspecting the exterior of the window. Check for areas of bare wood or cracked caulking that exposes the window to cold air.

Examine the interface of the sash with the frame. This includes the parting beads, and the staff bead. Examine the condition of the weather stripping (felt strips or foam tape) at these locations to determine if they are intact and working. If not, this needs to be replaced.

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

To fix the problem, apply a layer of fresh glazing putty onto the inside of your window. Using a flat-blade screwdriver, push the glazing points into position to hold them. Then, wrap a piece of foam and fabric around each point to form an insulation layer against cold air.

Aesthetics

A complete window replacement could be an expensive and time-consuming undertaking, particularly for older homes.

It is important to keep an eye on the condition and wear of window sashes to avoid major problems. If you're unsure whether your windows require repair It's a good idea to have them assessed by a professional. The cost of a sash repair is usually lower than the expense to replace the entire window, and can reduce your energy bills in the process.

The first step is to lower the upper sash towards the bottom - this is generally easy and will give you an unobstructed view of the "parting beads" (these are grooved pieces in the rails that join either side that keep the two sliding sashes from colliding). These can be removed with a blade that is attached to small pry-bars or a putty knife. They are usually put in place with nails and then painted, so be careful not to harm them or the sliding sash.

After you have removed the parting beads, you'll need to take off the covers for your pockets. These are tiny pieces of wood that are nailed into the frame at the bottom. They permit access to the sashweights. Once 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 doesn't, it could be an issue with the counterweights or sash cords. After you've inspected them all, you can fix them if necessary.
