It is not difficult to understand why cedar lap and gap siding is so popular on homes across Canada and North America. Although not a native tree to the North American continent it has been successfully cultivated here, especially in the northwest, for centuries.
Are you concerned about the strength or integrity of your floor joists? Do you have bouncy, sagging or otherwise dilapidated floors? Then you may want to consider sistering your floor joists to add the necessary strength to bear the load. Sistering floor joists is necessary when bouncy, saggy and creaking or just plain weak floor structures exist in your home.
You can have a structural engineer come out to tell you what you need to do if you can spare about $500, or you can probably see for yourself what the problem is by the way your floor behaves. If your floor has obvious sag or it creaks, cracks and bounces when you walk on it, chances are you need to remedy the problem before it becomes worse or someone gets hurt.
