Everyone who owns an old house needs to know how to restore old windows. There are lots of them and they usually need a lot of work, but with the tutorials, tools, and supplies on this page you can learn how to restore old windows like a a pro from a pro.
Your home’s old wood windows are some of the most valuable yet misunderstood elements of a historic house. Most people find them painted shut with sash cords cut and with missing bits and pieces of hardware. That’s the time they usually opt to start over with replacement windows.
But replacing historic windows is a big mistake and I don’t want you fall into it!
Reasons people choose to replace old windows:
- Inoperable windows
- Leaky and energy-inefficient windows
- Lead paint concerns
- Aggressive marketing from window companies
All these problems can be easily solved and you can make your historic windows just as efficient as a new window but much longer lasting!
The Facts About Historic Windows
1. Repairable – Historic wood windows are designed to be easy to repair. Unlike replacement windows where the whole window unit must often be replaced or factory repaired if an issue arises, historic windows can be repaired piecemeal. Each individual piece can be repaired, restored or replaced quite simply by the homeowner or local tradesman.
2. Upgradable – Your old windows may be drafty but they can very easily be weatherstripped and have storm windows (interior or exterior) added to dramatically increase their efficiency beyond even what new replacement windows can offer.
3. Simple to Maintain – Keep your old windows painted. That’s it! With some paint every decade or so you can keep them protected and safe for decades longer than a replacement window will last.
4. Resilient – Being made from old-growth lumber these windows (when properly maintained) can last for several centuries unlike replacement windows today which are obsolete within just a few years.
