Why We Do We Love Sash Windows Repair (And You Should Also!)
Sash Windows Repair
Pam attempts to salvage the original window. She makes use of a heat gun set to medium and equipped with nozzle shields to soften hardened, old putty (glazing compound) and a putty knife to scrape it away.
She then ties the bottom sash cords to ensure they don't pull into pockets for weights, and then takes off the metal hardware. She then stores it in a bag with a label.
Repairing the Sash
Old wooden windows, even when well maintained and repaired, might 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 repair or could be the result of the wood's swelling and contraction due to fluctuating humidity levels. The replacement of sash windows made of wood will allow the window to work more efficiently and smoothly.
To take the lower sash off, find the wooden pegs that connect the stile to the rail. Then using a mallet, or a soft-faced hammer (to prevent damage to the sash) take care to gently separate the stile and rail. Then, take off the muntins (the horizontal and vertical pieces that divide the glass panes). After you have removed the muntins, lift the sash up and place it on the table or workbench. Take the sash cords off. Cut them to the point at which they are tacked.
After the window has been fully cleaned, it's time to begin reassembling it. The author covers each sash reassembled using glazing compound using the small pry bar over a stiff-bladed putty knife. She then secures them with the glazier's points (one point on each side of the sash). In the end, she puts on a sash stop to keep it from being pulled completely down.
Reusing the sashcords is an excellent idea. Secure the back end of the cord to a pin or nail that protrudes from the top of the bead. This will hold the weight in place until you can attach the opposite end to the sash. After the cord is attached, temporarily nail or pin the weight to the bead. Leave the head protruding so that the load isn't slipping out of place.
After the sash has been assembled, it is hung in its frame. Then the vinyl track can be put back in place and then the lock terminals may be replaced by releasing each pawl on its locking terminal before turning them counterclockwise in order to reset their tension.
Restoring the Frame
The elements can have a huge impact on the interior and exterior of your sash windows, and it is often the scenario that the frame is more deteriorated than the sash. The frame is more vulnerable to the elements, especially in older houses where the sills weren't sloped as they are now. Water residue can collect on the sill, which could eventually cause the wood to rot. If the rot isn't treated, it can spread to other parts of the frame and compromise the structural integrity.
A specialist window restoration service can restore your sash and increase the energy efficiency. They can also fit discreet brush pile strips that help keep the window from rattling and to reduce drafts, without compromising the window's character.
Restoring your sash window can be a cheaper alternative to replacing them, and also add an air of history to your home. A reputable company can restore your windows with sash and ensure they are in best condition for the long term.
It is important to check that the hardware works correctly and that there are no leaks prior to attempting to fix the shash. If the sash isn't able to be opened and closed it might need to be replaced.
Once the sash is removed the old glazing putty can be scraped away, and the frames cleaned down to bare wood if needed. After repair of the damaged areas using a high-quality wood filler, such as Expoxy HighBuild, the frames can be sanded to remove any bumps or unevenness. After sanding, the area that has been repaired is primed and painted to guard against moisture and the weather.
Another common issue with windows made of sash is that the muntins (vertical and horizontal pieces of wood that divide each glass pane) can break or completely fall out. This is usually caused by soft or rotten wood, and can be prevented with regular inspections and maintenance. Regularly applying wood preservatives, such as varnish or linseed can protect the timbers and allow you to identify possible issues before they become serious.
Restoring the Glass
When a window is old, it begins to show signs of wear. Paint can chip, wood could rot or glass can break. When this happens it is time to consider sash windows repair .
The sash is a part of the window that contains the glazing bars and the actual glass itself. The sash is moved upwards and downwards to open and close the window. This movement is supported through a system weights and cords.
To keep wooden windows in good condition they must be maintained regularly. Untreated, the sash could begin to develop mildew mold or rot. The sash made of wood will expand and contract in response to changes in humidity after being exposed to the elements. This can cause the window to get stuck or jammed within its frame.
Cleaning and restoring the sash requires cleaning the glazing bar and glass and getting rid of any sanding dust or dirt that has accumulated on it. It's also a good chance to replace the weather strip that has worn out. If there's no weather strip, you can put one on the bottom of your sash. You can also apply a silicone spray or Teflon to grease the pulley axles.
After the sash is cleaned and reglazed it is an ideal time to inspect the wood for any damage. A test with a screwdriver can be performed to see whether the wood is soft or decayed, in which the wood must be replaced. The wood that is rotten is replaced with new timber, primed and painted.
Draught-proofing your window is a further option to enhance its acoustic properties. To limit the amount of air that flows between the glass panes large gases are introduced into the gaps. This will improve the thermal efficiency and reduce the noise emanating from outside. Draught-proofing also helps to reduce the cost of cooling and heating. This is particularly relevant in Minnesota, where energy bills can be very high. The repair of your sash windows and draught-proofed can be a huge improvement to the living space.
Restoring the Muntins
If you use the right techniques using the right techniques, even damaged muntins can be repaired. First tape strips of painter's tape to the glass. Then, apply a coat of slow-setting epoxy on the damaged muntin. Once the epoxy is dry then, you can scrape it with a sandpaper and create an ideal profile. Then using a rag soaked in white vinegar, clean the window and sand smooth before applying another coat of epoxy.
After fixing the frame, sash and glazing bars, you're now ready to paint the window. You can either buy new restoration glass through a dealer, or salvage old panes glass from a salvage yard. If you are looking for glass in an old salvage yard, be sure to find panes that are either the correct size or 4 inches larger than the ones you have now. This will make it easier to cut the glass to fit.
The upper and lower sashes are held together by two sets of rails which are horizontal strips that help keep them in their place. Stiles are the vertical pieces that join the two. Sash windows also have an elaborate arrangement of wood components: sash horns with a profile and sash guts around the glazing mouldings, scotia mouldings, precision-made staff and parting beads. All of these components must work together seamlessly, requiring millimetre-specific gap sizes and an under-the-hood system of pulleys and weights.
When old windows are reglazed in order to accommodate glass that is insulated, the original stiles, rails and frames are often routed out in order to accommodate the more dense glazing. This can not only reduce the transparency of individual light bulbs, but also affect the structural strength and cause damage over time.
Many homeowners opt to take out the sash and frame their window. While this may require an investment of some amount but it's typically less expensive than replacing the entire window. It can also help preserve your home's heritage features. It also won't alter the energy efficiency of your home. So whether you're in need of a quick fix or are seeking an investment for the long run, sash window restoration is a good alternative to consider.
