20 Resources That Will Make You More Efficient With Sash Windows Repair
Sash Windows Repair
Pam attempts to salvage as much of the original window as possible. She makes use of a heat gun set on medium, equipped with nozzle shields to soften hardened, old putty (glazing compound) and an ax to scrape it away.
She then knots the bottom sash cords in a way that they don't pull into pockets for weights, and then removes the metal hardware. She then stores it in a bag that has an inscription.
Repairing the Sash
Old wooden windows, even when well maintained and repaired, may not be able to open and close as easily as they should. This issue could be due to an improperly aligned hardware that is an easy fix or it could be due to the wood expanding and contracting due to fluctuating humidity levels. Replacement of the wood window sash will allow the window to run more smoothly and efficiently.
To remove the lower sash, first find the wooden peg(s) that connect the stile and rail together. To ensure that the sash is not damaged, use a soft-faced mallet or hammer to gently separate the stile from the rail. 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 workbench. Take the sash cords off. Cut them down to the point at which they are attached.
After the window has been fully cleaned, it's time to start 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 using glazier's points (one point on each side of the sash). Then, she adds the sash stopper to keep it from being pulled completely down.
Reusing the sashcords is a good idea. Tie the back end to a pin or nail that protrudes from the top of the bead. This will help hold the weight in place until you can connect the other end to the sash. Once the cord has been secured, temporarily nail or pin the weight to the staff bead again leaving the head protruding to prevent the weight from falling off during this process.
Once the sash is assembled, it can be hung onto its frame. The vinyl track should then be put back in place. The terminals for the lock are replaced by releasing the pawls of each terminal, twisting them in the opposite direction to reset the tension.
Restoring the Frame
The elements can impact on both the exterior and interior of sash windows. It is typical for the frame to become more damaged than the sash. The frame is more exposed to the elements, particularly in older homes where the sills were not angled as they are now. The water residue can accumulate on the sill and eventually cause the wood to begin to rot. If the rot is not treated, it can spread to other parts of the frame and weaken the structural integrity.
A specialist window restoration company can restore your sash, and improve its energy efficiency. They can also put in discreet brush pile strips that help keep the window from rattling and to reduce drafts, without compromising the style of the window.
Having your sash windows restored can be more affordable than replacing them and bring back a sense of history to your home. A reputable company will be able to restore your sash windows and keep them in their best condition for the long term.
It is important to check that the hardware functions correctly and that there are no leaks before trying to repair a sash. If window repairs opens and closes it may require replacement.
After removing the sash, the old glazing putty needs to be removed and frames cleaned to reveal the bare wood, if needed. The damaged areas can then be repaired with a high quality wood filler, such as Expoxy High Build, and sanded to eliminate any bumps or unevenness. After sanding the repaired area, it can then be primed and then painted to protect it from moisture and elements.
Another common problem with old sash windows is that the muntins (vertical and horizontal pieces of wood that divide the glass panes) can break or even fall off completely. This is typically caused by decayed wood or soft wood and can be avoided by regular inspections and maintenance. Regular application of a wood preservative such as linseed oil or varnish can keep timbers protected, and allow you to identify any potential issues before they become serious.
Restoring the Glass
If a window gets old, it begins to show signs of wear. Paint can chip, wood can be rotting, or glass could break. This is when it's time to fix your windows that are sash.
The sash is a component of the window that houses the glazing bars as well as actual glass. The sash is moved up and down to open and close the window. This movement is supported through a system weights and cords.
To keep wooden windows in good shape, they need to be maintained regularly. If left untreated the sash can start to develop mold, mildew or rot. The sash of wood can expand and contract in response to changes in humidity after being exposed to the elements. This could cause the window frame to get stuck or stuck.
Restoring the sash involves cleaning the glass and glazing bar and taking away any sanding dust and dirt that has collected on it. This is a great moment to replace the worn weather strip. If there's no weather strip, you can add one to the bottom of your sash. You can also use a silicone spray or Teflon to lubricate the pulley axles.
After the sash has been cleaned and reglazed it is recommended to examine the timber for any damage. The wood can be inspected with a screwdriver in order to determine if it's soft or rotten. If so it will need to be replaced. The wood that is rotten is replaced with new timber, primed and painted.
Another way to enhance the acoustic quality of the window is to make it protected from draughts. To reduce the amount air that passes between the glass panes, heavy gases are infiltrated into the gaps. This can improve the thermal efficiency and also reduce the noise emanating from outside. The addition of draught-proofing could also save money on heating and cooling costs. This is especially important in Minnesota where energy costs are very high. The repair and draughtproofing of your window sash can make a significant impact on the comfort of your home.
Restoring the Muntins
Even damaged muntins are repairable with the right techniques. The first step is to cover the glass by using strips of painter's tape. Apply a slow-setting epoxy coat to 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 dampened in white vinegar, scrub the window and sand it smooth before applying another coat of epoxy.
After fixing the frame and sash, as well as the glazing bars, you are now ready to paint the window. At this stage you can decide to purchase new restoration glass from a retailer or salvage old window panes from a salvage yard. When searching for glass at a salvage yard try to find glass that is either the right size or 4" larger than your existing panes. This will make it easier to trim the glass.
The lower and upper sashes are linked by two sets of rails which are horizontal strips that help keep them in position. Stiles are the vertical pieces that join the two. Sash windows feature a complicated arrangement of wood pieces that include sash horns with edge-to-edge profiles and sash guts which surround the glazing, scotia moldings and precision-crafted parting beads and employee beads. All of these parts are required to work in harmony with precise millimetre-sized gaps, and an array of pulleys and weights that are concealed inside the frame.
When windows are reglazed 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 does not just reduce the transparency of individual lights, it can compromise the structural quality of the sash, and cause the sash becoming damaged over time.
To avoid this, a lot of homeowners choose to remove the existing sash and reframe the window instead. Although this will require significant investment, it is often less expensive than replacing the entire window. It can also preserve your home's historic features. Additionally, it won't compromise the overall energy efficiency of your home. If you're in need of a quick solution or looking for an investment for the long run, restoring sash windows is a good option to consider.
