Weather stripping existing doors can be done using a variety of different methods. There are some simple, less durable methods, such as adhesive backed foam, or the installation of a metal and plastic or foam weather stripping installed on the door jambs. However, the best way that we have found is to use a special tool that cuts a small kerf, or groove, into the corner where the jamb meets the stop and to install a silicone bead into the kerf. This is a very clean and professional installation and avoids an unsightly metal strip, which often stands out as they only come in a few color options. In addition, these metal strips tend to snag clothing and get beat up over time. Conservation Resource Technology sells this tool, which even comes with an attached vacuum hose, for controlling the dust. This is especially important if the jambs have been painted with lead based paint. Installing weather-stripping in this way is also a great choice for well maintained, historically accurate, natural stained wood doors and jambs. Many homes in Portland still have original, stained wood door jambs that have been well kept. This is a great way to improve the performance of those beautiful old doors without compromising the beauty of the original mill work.
Windows in beautiful older homes pose another challenge. Again, how do we maintain and even add to the beauty and character of these homes, while improving upon the performance and functionality of these windows? Unfortunately, it is all too common for contractors and home owners to replace their old windows with new vinyl windows that perform better. However, the character of vinyl windows is a far cry from the beauty of a classic, divided lite wood double hung window. In addition, many older homes are protected by the State Historic Preservation Office (SHPO). Contractors and home owners are legally required to submit their work request to SHPO, but far too often, this work is done without the legal permission from SHPO.
There are companies out there that have made it their mission and passion to take these older windows and rebuild them to a state where they are better than new. They will remove the window sashes (the operable part of the window), strip down the paint, remove the glass and remove about 1/2″ of the wood on the inside of the sash with a router, making room for a new, insulated glass unit to be installed. They can also rebuild the counter weights, install new vinyl guides and hardware and install silicone rubber seals, similar to the one discussed for weather stripping doors above. If your window has divided lites, they will install new “applied muntins” where the muntins were previously to maintain the look of your old windows. With these techniques, you end up with a beautiful window, mostly original and you also have the opportunity to stain the windows instead of painting them. Your windows will now look, operate and perform far better than before.
Alternative options include sash only replacements, such as Marvin’s “Tilt Pac” among other manufacturers, or Indow Window’s tight fitting interior glass unit inserts. These options are less expensive than a historic window rebuild, but in my opinion, remain a compromise.
