Floor Leveling Significantly Improves the Quality of Living Spaces.

But, it also helps expose any underlying foundation problems — if found — that could be causing the floor to be out-of-level, to begin with. Repairing now can save you a bundle in repairs later.

Should Out-of-Level Floors Concern You?

Slightly out-of-level floors are normally not cause for concern. If your floor is slightly sloped, you may choose to have it leveled for aesthetic purposes.

Drastically sloping floors, however, should be addressed because it could be causing residual damage to your foundation. It could also be a symptom of structural problems.

A word to the wise, if your floor is extremely out-of-level, get it inspected by a licensed foundation contractor. Most of the time, drastically sloping floors are caused by drainage issues which, if not remedied, could lead to foundation problems. They may also be caused by earthquake tremors, in which case a seismic retrofit to strengthen your home's foundation may be necessary.

Floor Leveling Procedure

Generally speaking, the entire floor leveling process takes approximately 2-10 days. Whatever the underlying cause of out-of-level floors, floor leveling usually involves the following steps:

Shoring the Building

Oversized beams with precast piers and custom-cut posts are strategically placed beneath the floor joists to temporarily support the structure.

Separating the Building from its Foundation

The foundation anchors are disconnected from the sill plates, and if needed, the stucco is broken at the sill plate level.

Leveling the Building

A gentle lift is created using hydraulic jacks. The building is raised slowly and just enough to minimize any damage to the interior of the home. An expert field technician monitors the effect of the movement on both the inside and the outside of the structure and takes interior elevation measurements throughout the leveling process.

Adjusting the Foundation

Once the floor has been leveled, the existing foundation is adjusted as necessary to ensure that it will be able to support and maintain the now-level floor.

Foundation adjustments are implemented on a case-to-case or on a need basis. A new cripple wall, concrete piers, posts, and girders may be installed to make the floors level and to ensure that they will stay level.

I have seen Sinai Construction's signs around my neighborhood for some years now so when I started to notice cracks in the walls getting larger fairly quickly I immediately thought of calling them for an Inspection. I additionally looked up online 2 other companies that advertised heavily. Sinai Construction was the only company that spent a considerable time (close to an hour) crawling under the entire crawlspace and inspecting closely the perimeter of the house. Needless to say, their analysis matched their inspection; not only did they find out the problems in my foundation, but they also found what caused them to begin with. What really surprised me was that their proposal for the repair work was very close to the lowest bidder which failed to address the needed work to ensure this doesn't happen again. I now know why I have seen so many of their signs for so long.
