subject: Understanding Sash Window Restoration And The Environmental Benefits [print this page] Many companies will try and convince you that you need to replace those old sash windows to be environmentally correct but actually a sash window kept in good repair is both better for the environment and less costly than replacing all of your beautiful old windows. Sash window restoration and the environmental benefits are really not so hard to understand.
There are many companies that offer restoration services and when getting quotes pay attention to the details. A real red flag would be a company that offers speedy service. This can be a quick fix at a cheap price but you will want someone who will do a good job and make sure what they are doing is full restoration and not a fast repair.
These services can range from full sash window restoration to simply replacing a broken sash cord. A trustworthy company will be all inclusive and will also recommend when your window is beyond repair and replacement is necessary.
The time and cost investment is based on the number of windows in your home. You can expect that normally one or two windows can be done in a day if it is just a basic repair.
The two really important things about sash window repair are that the wood has integrity and there is a good coat of paint protecting it. These two things combined with weather seals, double glazed glass and re-balancing will ensure you have top notch windows in your home operating at peak performance. This will ensure that you have a draft-free window that retains heat and will last you for many more years.
Should you want to do the work yourself keep in mind to strip the sash, box and sill down to the wood. Fill in holes with a high-quality, two part, resin-based product and fix the joints. Weather seals will need to be placed at the top, bottom and sides as well as the meeting rails. Check the sash cords and replace them and the pulleys as needed and re-balance when complete. Use a highly resilient paint over a base coat.
As a good practice it would be best to replace all the ropes inside of the sash as with time they will rot and leave you with an unbalanced window that is hard to operate. Replace the rope, re-attach the counterweights and balance. While doing this, replacing the pulley wheel might be a necessity as they get painted over and get stuck and create stress on the rope. There are many metal finshes to choose from or an economical steel/nylon wheel is available. Sometimes you can salvage the pulley by applying a little lubricant to get the wheel turning again.
If you find you need to restore the sash, box or sill using a good hardwood will ensure the longevity of the window and be sure to match the joinery methods of the original window. Match the window detail and double glaze. Replace all painted over hardware with new and youve got functional windows without cost of replacing them and using new materials.
