Hardwood Floor Installation - Glue or Nail?

Hello! Trying to have hardwood floor installed for Mom as a gift. Cannot afford to install in all rooms, only living room and hallway. After viewing home, contractor says gluing new floor is best, most economical option for different reasons: 10 because current parquet floor is very even and is good surface for glue, and 2) because new floor cannot be installed all over house, gluing wood keep the new floor at the approximate level of the flooring in the areas of the house that will not have new floor. The wood floor store says that nail installation and subfloor creation is the best option, because humidity in NYC could cause a glued floor to shift and cause gaps between wood pieces. However, the nailing/subfloor installation option would create different floor heights throughout the house. Even with reducers, new floors would cause significant height difference.Nailing option is obviously more expensive, would involve ripping up the current parquet, which is in excellent condition (but too thin for nails). Nail installation would also involve changing the closet doors as well as the entry door to the home. New wood flooring is 3 and 1/2inch mahogany, and is 3/4 inch thick. Current home foundation is 1/2 inch parquet glued to concrete. Home is 7th floor apartment in Manhattan, created in 2003. Building is 8 floors high. Wood store is ready to perform either glue or nail option, but I need to decide. Any suggestions as to which is best installation option - gluing or nailing? Want to please Mom. Please help!

Re: Hardwood Floor Installation - Glue or Nail?

Have you already purchased the flooring or can the order be changed. I think in your situation your best bet would be to go with an engineered floor. It is usually about 3/8" thick and made of multiple plys of wood with a real wood veneer on top. The top layers thickness determines whether it can be refinished or not but usually this type of floor comes with a 25 year warranty.

The benefits of the floor are
1. It is more stable than hardwood since it is made up of multiple plys of wood so it won't expand and contract as much.
2. It looks just like a real wood floor because the top layer is real wood unlike the cheap plastic laminate wood floors.
3. It can be be put down in three different manners, Nailing to the sub-floor, Gluing to the sub-floor, or glued together where it floats over the sub-floor.

In your situation gluing together and floating over the sub-floor may be the best option. A foam pad is first put down and the floor sits on top of that. This gives a little more cushion under the floor and makes it a little more comfortable to stand on. Check with the flooring store and see if this in an option for you. I'm actually surprised they didn't suggest it in the first place. Good luck in your project.
