Sash Windows Repair
Pam is determined to save the original window. She uses a heatgun set to medium, with an nozzle guard to soften the old, hardened glazing compound (putty) and then a putty knife to scrape the old compound off.
She then ties the bottom sash cords to ensure they don't get pulled into the pockets for weights, then takes off the metal hardware. She then puts 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 or close as smoothly as they ought to. This issue could be caused by misaligned hardware that is relatively simple to fix, or it could be due to the wood expanding and contracting due to fluctuating humidity levels. The replacement of the wooden window sash could help your window run more efficiently and effortlessly.
To remove window glass repairs locate the wooden pegs which connect the rail to the stile. Then, using a mallet or soft-faced hammer (to protect the sash), gently separate the rail and stile. Then, take off the muntins (the vertical and horizontal pieces that separate the glass panes). After removing the muntins, lift the sash up and rest it on the table or work bench. Then, remove the sash cords from the pulleys and cut them through below where they are connected to the staff bead.
Once the window has been completely cleaned, it's time to start reassembling it. The author uses a small pry bar to apply glazing compound over a stiff-bladed, putty knife. Then, she attaches each window sash that has been reassembled by using the glazier's tips (one on each side). She adds a sash-stop to prevent it from being completely pulled down.
Reusing the sashcords is a good idea. Secure the back end of the cord to a pin or nail that extends from the top of the bead. This will hold the weight in place until you can attach the opposite end to the sash. Once the cord is attached to the staff bead, you can temporarily pin or nail the weight to the staff bead and leave the head protruding to keep the weight from falling off in the process.
After the sash is reassembled it is then hung from its frame. Then the vinyl track can be put back on and then the lock terminals can be replaced by releasing each pawl from its locking terminal, then twisting them counterclockwise to reset their tension.
Restoring the Frame
The elements can have a significant impact on the interior and exterior of your sash windows and it's usually the case that the frame will be more damaged than the sash. The frame is more exposed to the elements, especially in older houses where the sills were not sloped like they are today. Water residue can build up on the sill and eventually cause the wood to rot. If the rot is not treated, it could extend to other areas of the frame and compromise the structural integrity.
A specialized window restoration company will restore your sash, and improve its energy efficiency. They can also put in discreet brush pile strips that help stop rattling and reduce drafts without compromising the style of the window.
Having your sash windows restored is more cost-effective than replacement and will bring back a sense history to your home. A reputable business can fix your sash windows and ensure they are in best condition for the long term.
It is crucial to verify that the hardware works correctly and there are no leaks before attempting to fix a shash. If the sash no longer can be closed and opens, it could require replacement completely.
Once the sash is removed the old glazing putty can be scraped away, and frames cleaned down to bare wood when needed. After fixing the damaged areas using a top-quality wood filler like Expoxy HighBuild the frames can be sanded to eliminate any bumps and unevenness. After sanding the area, it can then be primed and then painted to protect it from elements and moisture.
The muntins, the vertical and horizontal pieces of wood that separate each pane from the glass in old sash windows frames, can also become loose or fall out. This is usually caused by decayed wood or soft wood and can be prevented through regular inspections and maintenance. Regularly applying a wood preserver like linseed oil or varnish can keep the wood protected and help you to identify any issues that could be present before they become serious.
Restoring the Glass
If a window gets old, it begins to show signs of wear. Paint can chip, wood may be rotting, or glass could break. When this happens it is time for a sash windows repair.
The sash is the part of the window that houses the glazing bars and the actual glass itself. The sash moves up and down to open and close the window. The movement is supported by cords and weights.
Wooden windows with sash need regular maintenance to ensure they are operating properly. If not treated, the sash may start to develop mildew, mold, or rot. The wooden sash will also expand and contract with changes in humidity when exposed to the elements. This could cause the window frame to get stuck or jammed.
Cleaning and restoring the sash requires cleaning the glazing bar and glass and removing any sanding dust or dirt that has accumulated on it. It's also an excellent chance to replace the weather strip that has worn out. If there is no weather strip to be installed, it can be attached to the bottom of the sash, and the silicone or Teflon spray can be used to lubricate the pulley axles.
It is a good practice to inspect the wood for any damage after the sash has been cleaned and reglazed. A screwdriver test could be carried out to determine whether the wood is soft or rotten, in which case it needs to be replaced. The wood that is rotten is replaced with fresh timber primed and painted.
Another option to enhance the acoustic qualities of the window is to have it protected from draughts. To decrease the amount of air that is able to pass between the glass panes gas-filled vapors are injected into the gaps. This will improve the thermal efficiency as well as reduce noise from the outside. Draught-proofing can also help reduce cooling and heating costs. This is particularly relevant in Minnesota, where energy bills can be very high. Having your sash windows repaired and draught-proofed will greatly improve the living space.
Restoring the Muntins
Even damaged muntins can be repaired with the right techniques. The first step is to shield the glass with strips of painter's tape. Apply a slow-setting epoxy coat to the damaged muntin. Once the epoxy is dry then use a scraper to create an unharmed profile. Then using a rag that has been soaked in white vinegar, scrub the window and sand it smooth before applying a second coat of epoxy.
After fixing the frame, sash and glazing bars, you are ready to paint the window. At this point, you can choose to purchase a new restoration glass from a retailer or salvage old window panes from a salvage yard. If you're looking for glass at an old salvage yard, be sure you look for panes that are either of the right size or four inches larger than your current ones. This makes it easier to cut the glass to fit.
The upper and lower frames slide into each other and are connected by two sets of rails (the horizontal strips that hold the sash) and stiles (the vertical pieces that link them). Sash windows also have an intricate arrangement of timber parts: sash horns that are profiled and sash guts that surround glazing mouldings, scotia mouldings, precision-made parting beads and staff beads. All of these components must be in sync, requiring precise millimetre gap sizes as well as an invisible system of pulleys and weights.
When historic windows are reglazed with glass units that are insulated the original rails and stiles often get removed to accommodate the deeper thickness of the new glass. This can not only decrease the transparency of the individual lights, it can compromise the structural integrity of the sash and cause damages over time.
Many homeowners choose to remove the sash that is currently in place and frame their window. This will require a significant expense, but it's usually less expensive than replacing the whole window. It will also help preserve your home’s historical features. It won't also affect the energy efficiency of your home. Sash window restoration can be an excellent option, whether you are looking for a quick fix or an investment that will last for a long time.
