Obed,
We have been looking at hardwood flooring as well. Some of the ones we like the best are bamboo. It is suppose to be very durable, not very sensitive to moisture and very sustainable if that is a concern of yours.
Russ,
Bamboo is a grass. It grows very fast, which makes it a renewable source of material. Due to this feature, it's being pushed as a "green" alternative to wood for flooring.
Unfortunately, it's a very soft material compared to wood. What you are buying when you get bamboo floors is really a degree of hardener and/or sealer to protect the bamboo. Kind of like electric cars. People think they are saving the planet by buying toxic batteries filled with acid that require more power plants to charge these vehicles. Same thing with bamboo. You have to use more chemicals and polutants to make it and protect it.
Then there is the real problem with bamboo. Depending on the quality of the chemicals used on it, is how long it will take for wear patterns to show. High traffic areas will wear out very quickly compared to wood. If you have a desk with a chair on wheels, it will show extremly quickly. Dogs are also good at scratching it, and once you break through the finish, it's just get worse at a rapid rate.
I'm no expert on it, and have never tried to sand and seal it after it's started to show wear. I've been asked to bid it out, but decline every time. I've seen it fail in just a few years, but don't know all the details or brands that sold it. I've never seen wood, or even engineered wood fail like I've seen bamboo wear out.
The only thing worse than bamboo for a floor is cork.
If you really want bamboo, I would suggest you buy the most expensive product out there from a company that you have researched and know for a fact has a really good finish on it that has proven to last the test of time.
As for warrantees, they are pretty much worthless. If you call them on it, and they agree that there is a claim and honor your warrantee, they will just give you more flooring. You have to figure out what to do with it. Remove the old and install the new is on you. It's also where all the money is. I don't know of any manufacturers that include labor in their warrantees, and I don't know of any installers who will replace flooring that fails because of manufacterer defects. They installed it correctly, it wasn't their fault, type of reasoning.
Good luck,
Eddie
