This article will tell you everything you need to know about replacing a wooden floor, including how much it will cost, what steps to take, and what other good flooring options.

The Importance of Wooden Floor Maintenance

Wooden floors bring a touch of elegance and warmth to any home or office. In older homes, it’s not uncommon to find a beautiful parquet or plank floor with a wooden beam subfloor.

However, if the subfloor is not properly ventilated or if there’s dampness, rising dampness can result in problems like mold and wood rot. In these situations, the wooden floor must be replaced, and a concrete floor should be installed as a new subfloor.

Identifying and Replacing a Rotting Wooden Floor

If you see black or dark brown spots on the wood, it’s a sign of moisture, and the wood floor is likely rotting.

If the rot is addressed on time, you may only have to replace a small part of the floor. However, it’s essential to identify and address the cause of the wood rot to prevent it from recurring.

Reasons for Wooden Floor Breakage

A healthy wooden floor can bear a considerable amount of weight. However, if the floor is damaged, it can break differently.

The most common cause of breakage is contact pressure, which occurs when a joist head starts to rot in the subfloor.

If the pressure becomes too great, the wooden beam will give way, and the floor will break. Shear is another reason for breakage, which occurs when there’s too much tension on the beam where the floor rests on the foundation.

If this tension becomes too great, horizontal or vertical cracks can occur, causing the bar to break. Finally, as wooden beams age, they can bend so far that they suddenly break.

For larger floors, it’s recommended to make separate compartments with a concrete pouring capacity of one day. This way, you can fill up a section every day if pouring concrete for several days.


Concrete reinforcement should be applied to prevent cracks in the floor.
