Sash Windows Repair

Pam attempts to salvage the original window. She uses a heating gun set on medium and equipped with nozzle shields to soften hardened, old putty (glazing compound) and an ax to scrape it off.

She then knots the bottom sash cords to stop them from slipping into pockets of weight and removes the hardware. She stores it in a bag with a label.

Repairing the Sash

Old wood windows even if they are well maintained and repaired, may not be able to open and close as smoothly as they ought to. This problem could stem from an improperly aligned hardware that is fairly simple to fix. Alternatively, it could be a result of the wood shrinking and swelling caused by changing humidity levels in the surrounding. The replacement of the wooden window sash could help your window run more efficiently and smoothly.

To take the lower sash off, locate the wooden pegs which hold the rail to the stile. To avoid damaging the sash using a mallet with a soft face or hammer to gently separate the rail from the stile. Then, you can remove the muntins - the horizontal and horizontal pieces of wood that divide the glass panes. After the muntins are removed take the sash off and rest it on a table or workbench. Then, you can remove the sash cords from their pulleys, and cut them through below the point where they connect to the staff bead.

After the window is cleaned, reassemble it. The author uses a small pry bar to apply glazing compound using a stiff-bladed, putty knife. She then attaches each window sash that has been reassembled by using the glazier's tips (one on each side). Finally, she adds an sash stopper to prevent it from being completely pulled down.

Reusing the sashcords is a great idea. Attach the back end to the bead with a nail or pin that protrudes from the top of the bead. This will hold the weight in place so you can connect the other end to the sash. Once the cord is connected, you can temporarily pin or nail the weight to the bead. The head should remain protruding so that the weight isn't slipping out of its place.

After the sash has been reassembled, it should be hung into its frame. Then, the track made of vinyl can be reinstalled, and finally, the lock terminals may be replaced by releasing each pawl from its locking terminal, then twisting them counterclockwise to adjust their tension.

Restoring the Frame

The elements can have a significant impact on both the interior and exterior of your sash windows, and it is often the situation that the frame will be more damaged than the sash. This is due to the fact that the frame is exposed to the elements, especially in older homes where the sills are original and don't slope like modern ones. Water residue can collect on the sill and eventually cause the wood to begin to rot. If the rot isn't treated, it could spread to other parts of the frame, and may compromise the structural integrity.

A specialist window restoration firm can repair your sash windows, and increase their energy efficiency. They can also install brush pile strips that reduce drafts and stop the window from shaking.

Restoring your sash windows can be more affordable than replacing them and bring back a sense the past to your home. A good quality company can fix your Sash windows and keep them in their best condition for years to come.

It is important to check that the hardware is functioning correctly and there are no leaks prior to trying to repair a sash. If the sash isn't able to be shut and opened it could need to be replaced.

After the sash has been removed and the old glazing putty can be scraped away and frames cleaned to bare wood where necessary. The damaged areas can be repaired with a high quality wood filler like Expoxy High Build, and sanded to eliminate any bumps or unevenness. After sanding the repaired area, it can then be primed and finally painted to guard against elements and moisture.

Another common issue with old sash windows is that the muntins (vertical and horizontal pieces of wood that separate each pane of glass) could break off or fall out completely. This is usually caused by soft or decaying wood, and can be avoided by regular inspections and regular maintenance. Regularly applying a wood preservative like linseed oil, or varnish can keep the timbers safe and allow you to identify any issues that could be present before they become too serious.

Restoring the Glass

If a window gets old, it starts to begin to show signs of wear. Paint may chip, wood may rot or glass can break. This is when it's time to repair your windows that are sash.

The sash is an element of the window that contains the glazing bars as well as actual glass. The sash is moved up and down in order to open and close the window. The movement is supported by the system of weights and cords.

Wooden sash windows need regular maintenance to ensure that they are operating properly. Untreated, the sash could start to develop mildew, mold, or rot. Exposure to the elements also causes the sash of wood to expand and shrink as humidity changes. This could cause the window frame to become stuck or jammed.

Cleaning and restoring the sash requires cleaning the glass and glazing bar and removing any sanding dust or dirt that has collected on it. This is a great opportunity to replace any worn weather strip. If there is no weather strip, it can be added to the lower part of the sash. the silicone or Teflon spray can be used to grease the pulley axles.

It is a good practice to check the wood for damage after the sash was cleaned and reglazed. A screwdriver test can be performed to see whether the wood is soft or rotten, in which case it needs to be replaced. The new wood is then inserted into the areas that are rotten and primed and painted.

Another option to enhance the acoustic properties of the window is to make it draught-proofed. To decrease the amount of air that flows between the glass panes, gas-filled vapors are introduced into the gaps. This can significantly increase the efficiency of the window as well as reduce the noise emanating from outside. The addition of draught-proofing could also save money on heating and cooling bills. This is particularly important in Minnesota where energy costs can be very high. Restoring and draughtproofing your windows can make a significant improvement to the comfort of your home.

Restoring the Muntins

Using the right techniques, even damaged muntins can be restored. First tape strips of painter's tape to the glass. Then apply a coat of slow-setting epoxy on the damaged muntin. After the epoxy has dried using a scraper, sculpt it to resemble a pristine profile. Then wipe the window clean with a rag dampened with white vinegar. Sand it smooth prior to applying another coat of epoxy.

After fixing the frame, sash and glazing bars, you are now ready to paint the window. You can either buy new restoration glass at this stage through a dealer, or salvage old panes glass from an estate sale. When looking for glass at an auction you should look for glass that is either the proper size or 4" larger than your existing panes. This will make it easier to cut the glass.

sash window repair and upper sashes slide inside the frame, joined by two sets of rails (the horizontal strips that support the sash) and stiles (the vertical pieces that link them). Sash windows feature a complicated arrangement of wood components comprising sash horns that have sharp edges and sash guts which surround the glazing, scotia moldings, and precision made parting beads and employee beads. All of these components must be in sync, requiring millimetre-precise gap sizes and an under-the-hood system of pulleys and weights.

When old windows are reglazed to accommodate insulated glass units the original stiles and rails, as well as frames are usually routed out in order to accommodate the more dense glazing. This may not only affect the transparency of the individual light bulbs, but can also weaken the structural integrity and lead to damage over time.


To avoid this, a lot of homeowners opt to remove the existing sash and reframe the window instead. This is a substantial investment, but it is often cheaper than replacing the entire window. It will also help preserve your home's heritage features. Additionally, it won't reduce the energy efficiency of your house. Therefore, whether you're in search of a short term solution or are seeking an investment that will last for a long time, restoring sash windows is a great option to think about.
