What causes soft spots in floors? What can be done to prevent that? How serious is it?
Soft spots maybe the result of moisture from a leak. They may also be the reult of poor construction techniques and inferior sub floor material.
They can easily be avoided however the manufactures have to committ to designing and building a better unit vs. building units with known construction flaws and selling them anyway.
On the other hand consumers cannot me so price focused that they refuse to buy the prperly built unit, because they don't wnt to pay a few grand more to get a unit that was built right from the start.
