Engineered flooring questions
DH and I are doing a kitchen remodel, which is leading to replacing the dark stained oak hardwood floor that runs through the mud room, kitchen, and dining room. I've had several floor guys out, and have been told the existing floors can't be reliably refinished. They've been taken down already, the floors have v-grooves, and the results would likely be very uneven and unsatisfactory.
We would like to install engineered, pre-finished floors. We're very handy DIYers (or at least DH is), but like the idea of easy. And, of course, budget is important. The house is 45 years old, and very solid. Floor joists are 16" OC and the subfloor is 1" thick. There is linoleum that we plan to leave where it's tightly adhered (most of it seems to be). We live in the San Francisco Bay Area, so humidity is not a huge issue. My dream is to have a floor that will really be fine for 20 years. We have no dogs or children.
So, my questions:
1) Is my dream of 20 years with no repairs/refinishing possible, assuming no accidents and proper care?
2) Can we get good results out of floating vs. gluing?
3) How much harder is it to glue install?
4) Is Columbia a good manufacturer? We like the look - and the sale price - of the Beacon Oak Natural Red Oak. Are there others who harvest/mill/manufacture in the US who are reasonably priced?
5) What else should I know?
