Uneven transitions between rooms can be awkward at best. If your home is for sale, unleveled floors can cause prospective home buyers to walk away-possibly at a slant. Repairing uneven floors can be a challenge, but well worth the difficult task and certainly to help sell your home in these difficult times. Make your home stand out by repairing and leveling floors.
A substrate or sub-floor is the surface that provides bonding and support for the actual floor. Typically a substrate is made from concrete or wood. Carpet, tile and hardwood flooring then cover the substrate/sub-floor. This is also where most of the problems for uneven flooring arise.
Repairing wood floor substrates can be a difficult challenge, but can be overcome by a few different techniques. Plywood needs to be removed and joists should be replaced as needed by attaching new support members to the side of the old ones. Once they have transferred the load, shave down the old ones as needed with an electric planer.
Concrete floor leveling can be a little more involved but done just as easily. Dips can be filled in with self leveling concrete. If you’ve got a little skill with a concrete mag or trowel, you can fill the dip with thinset and level it yourself.
Rises in concrete require a little more finesse; the highest part of the concrete slab must be the starting point to level out the each wall. A line can then be leveled around the room’s wall. The area can then be filled with thinset or self leveling concrete to remove the hump.
Sometimes filling a hole in a slab isn’t going to cut it. Transitions between renovated structures just can’t be helped. So what is there to do about awkward transitions?
Creating a slope to resolve step down transitions can ease the problem of difficult room transitions. Wood transitions can be eradicated by ripping down 2×4’s from the highest step down to nothing-cutting it the length of the slope using the 20-to-1 ratio. For every one inch of step, you need to extend the slope 20 inches.
Concrete can be done the same way. Simply thicken the thinset, mortar or self leveling concrete and then slope it to the same 20-to-1 slope ratio. You can use regular concrete with stone aggregate to fill large voids, and then fill the rest with thinset to create the perfect concrete transition and gentle slope.
