So the question is, how do you level sinking floors? Screw jacks, also known as adjustable floor jacks, are a useful tool when leveling sagging or uneven floors.

When basement floors or crawl spaces sag, they are often caused by weak joists, girders or posts. Construction is not always the reason for foundation failure. Other causes can be a result of heavy loads or home additions. If you suspect structural issues, contact our team of experts so we can look for insect activity, wood rot, or inadequate footings.
What is screw jack installation? Screw jacks consist of two steel tubes, one inside the other. The inside tube is threaded and can be adjusted with a wing nut. The pipe can adjusted up and down to the desired height for leveling the home's foundation.
When should screw jacks be replaced? Improper screw jack installations can eventually collapse. Some examples of poor installations include:
If your screw jacks have these issues, we can replace your screw jacks. By installing them with the screw downward against the floor, this allows the post to be placed against a steel plate and onto the underside of the beam. Also, it lowers the chances of a bending steel plate.
