Average Cost to Level the Floor in a House
On average, you are looking at about $3 – $5 per square foot.
Uneven floors are responsible for countless injury-causing falls each year. Whether it's a case of warped hardwood or bunched up carpeting, an uneven floor surface can spell danger for just about any unsuspecting person nearby.
The best flooring for uneven floors due to its attractiveness and durability is epoxy, which can also be designed to mimic a wide variety of appearances. Not only will epoxy finish out the floor, but it'll also even it out.
For homes where this is the case, the subfloors likely need to be replaced. According to Angi and HomeAdvisor, the cost to replace a subfloor ranges from $428 to $2,978, with a national average of $572.
Underlayment can help smooth things out, though, but the type you choose will vary depending on your specific reasoning for wanting an even subfloor. That can make choosing the right one for you rather tricky, so here's a quick guide that should lend a helping hand in getting the best underlayment for uneven subfloors.
Forgetting to level the subfloor
The subfloor must be level before installing laminate flooring. If the subfloor is leveled, the laminate planks will not lay properly, causing uneven and unsightly floors. If the subfloor is not level, you can use a self-leveling compound to level it out.
No subfloor is perfectly level, but any signs of unevenness and high or low spots must be remedied. Please follow these requirements: Subfloor unevenness cannot be greater than 3/16 of an inch over a 10-foot span or 1/8 inch over a 6-foot span. Subfloors must not slope more than ½ inch per 6 feet (25 mm per 1.8 m)
You can install vinyl on many types of subfloor, including concrete and wood. But that floor must be flat for your installation to be a success. An uneven subfloor can lead to potential problems, such as planks having varying heights that will make the flooring unstable and wear down more quickly.
Many homes older than 15 years tend to experience some sort of foundation issue or settlement. Slab, basement, and crawl space foundations are all at risk of settlement, which can cause your floors to warp, bend, and become uneven.
A damaged foundation and damaged floor joist are often the leading cause of uneven and sloping floors in an old house. Foundation damage can come from dump crawlspace, aged or poor design, and craftsmanship, resulting in a foundation too weak to hold up your house's weight, especially when you have a wood floor.
If the floor sags more than a few inches, it may collapse completely, putting everyone in your house in danger. Sagging floors can also cause misalignment of doors and windows, making them harder to open and close. Sagging floors can even crack the walls of your home in extreme circumstances.
While sagging floors are unsightly, they can be dangerous as well. A sagging floor means that it has lost support, and it may eventually collapse into lower levels of the home. The overall structure of your home could be at risk, therefore making repairs a priority is imperative.
Mix and Apply the Self-Leveling Compound
Pour a generous amount of leveler onto the subfloor and spread it over the floor with a towel, allowing it to settle into low areas. The product will seek its own level (much like water), but it must be spread out so it covers the affected area without pooling.
There are self-leveling coatings designed to fill gaps and cracks. You could also try using vinyl floor tiles to make the transition more gradual. Probably the easiest (and cheapest) thing to do would be to get a big diamond grinding wheel and bevel down the lip.
If you want to raise the height of a floor, the cheapest and easiest way is to add a thick underlayment designed for the job. There are other options too like adding a framed wooden subfloor or floor leveling compound before installing new flooring.
Many homeowners and owners of commercial property have dealt with a sagging floor. Floors can sag for many reasons. For instance, they may sag due to the natural settling of your property or building materials over time. However, a sagging floor may also signify damage from water leaks or pests, like termites.
Sagging floors can indicate there's damaged wood under your flooring, that one of your supports is deteriorating, or that there are problems with the foundations. Here are some other signs that you've got issues with your surface and how to fix sagging floor joists.
Most flooring manufacturers recommend a variation of no more than 3/16 inch over a 10-foot span. Floor leveling is a relatively easy DIY project, although some subfloors with rot, insect damage, or structural issues may require professional attention.
The degree to which your floor slopes or sags indicates whether or not you have reason for concern. Typically, floors that slope 1-1/2 inches or less in 20 feet is not a problem. Floors that sag 2 inches or more in 20 feet, though, are a cause for concern.
