Top 4 causes of uneven floors and how to fix them

Have you realised that your floor isn’t level? As you make your way across the room, do you feel as though you’re walking uphill or downhill? Or your furniture doesn’t sit quite right?

Whilst older properties typically have more slopes and sags than newer builds, an uneven floor can become uncomfortable or difficult to walk or sit on. It can be unsightly and pose a serious hazard for the elderly and frail or the very young, too.

In this article, you can explore a few of the most common causes of uneven floors and find out how to fix them efficiently. Perhaps you could benefit from JCW’s floor screeding services?

4 reasons why your floor might not be level

  1. Poor structural design – foundation damage often comes with age or poor craftsmanship. This can make the foundation too weak to support your property’s weight and, as a result, causes warping, cracking and unevenness in the floor.

Depending on the extent of the damage, foundation repairs can be costly. However, floor jacks and foundation peering techniques can be used – pumping grout into strategically placed holes to raise the foundation to the required level. Unique footing and piers then stabilise the foundation.

  1. Exposure to excess moisture – water damage or an excess of moisture can also cause floors to slope. Whether water is coming from a leaky pipe in the wall or groundwater, it can cause the wooden beams and sub-flooring to warp. Where drainage is poor, moisture can also impact the foundations, resulting in them moving and possibly cracking.

As with most things, the sooner you identify the problem, the sooner you can seek professional guidance – and the easier it will be to rectify. If moisture is seeping in through a leaky pipe, call a plumber to fix or replace it. Depending on the damage done, the flooring may also need to be replaced.

  1. Soil movement – soil expands when it’s wet and shrinks when it’s dry. Though soil movement is natural, if builders laid the foundation of the house without compacting the soil beneath, it can cause your foundations to move over time which can make your floors shift and sag.

A great way to resolve soil movement is to provide adequate drainage around your property’s foundations. This will ensure that water is navigated away from the building. Alternatively, you could consult a professional to fix your foundation grading – ensuring it has a ground slope of 3-5% around the outside of your home – or add a slanting swale to prevent moisture from seeping into the foundations.

  1. Tree roots – an uneven floor can also be the result of tree roots that grow beneath the foundation. Aside from causing it to crack and expand, these roots will draw moisture away from your floors, leaving the foundations dry.

Always seek professional help to alleviate the problem both quickly and safely. And as a general rule of thumb when planting trees around your property, try to plant them as far away from the foundation as possible.

What about floor screeding?

Floor screed is a perfectly blended mix of sand and cement that’s poured over the top of a subfloor to create a smooth, flat, durable surface. The process is known as ‘floor screeding’.
