It is really important that you properly prepare your subfloor before installation. If it has not been done correctly, it can cause your flooring to become damaged. The most important things to check are whether your subfloor is flat, level, clean and dry.
Sometimes the subfloor will also determine the type or thickness of the flooring. For example, if you have joists, you wooden flooring must be at least 18mm thick. Why not have a look at Fitting wood flooring onto different subfloors for further information.
It`s important to keep in mind that wood floors are natural and will be affected by the environment. While there`s no need to panic if you see some gaps develop between boards during dry seasons, if the wood doesn`t shrink back into place during humid seasons — July through August, then you should bring in a certified wood flooring professional to assess the separation.
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.
A sun-kissed glow looks great on skin but not on wood floors. Inspect floors once a month — don`t forget to peep under rugs, too, and if there`s any discoloration, it`s time to consider a fresh topcoat.
If you have a busy hallway or living space then something durable like Oak might suit you. Alternatively, for a quieter room, you could choose a more delicate wood, like Walnut.
