Hardwood floors are durable and natural, come in a variety of species, are hypoallergenic and easy to maintain. When well maintained these floors can last a hundred years.
Hardwood planks can be purchased with a raw face that gets finished by a professional after installation, or prefinished, which arrives with the stain and topcoat already applied. The advantage of prefinished wood is that you know exactly what you`re getting.
For basements and apartments with concrete subfloors, engineered flooring offers an installation advantage. Whereas solid wood is generally installed over one or two layers of plywood, which can raise the height of a floor and interfere with existing doors or marginally reduce ceiling height, engineered flooring can be glued directly to concrete, or over a soundproofing mat.
Hardwood is a natural product and will inevitably expand and contract with changes in heat and humidity. By letting you hardwood flooring acclimatising to your home, you are reducing the risk of damage to the wood once installed.
The reason you need to do this is to give your hardwood flooring space to expand and contract with changes in temperature and humidity. If you fail to leave an expansion gap your flooring will have no space to expand and can easily become damaged.
