Tile Flooring Installation in Lilburn, GA
Very few floors are as flat as tile needs them to be. Slabs settle and dip near the walls, wood subfloors crown over a joist, and old patches leave ridges. Those highs and lows get measured early in any Lilburn tile flooring installation, because correcting them is often the step that decides how good the finished floor looks.
The leveling work then carries through to the grout joints, the finished height at each doorway and the estimate you receive.
Measuring how flat the floor really is
Flatness is checked with a long straightedge or a laser, moving it in several directions and noting every gap underneath. Tile and setting-material makers publish how much variation they allow over a given distance, and the allowance gets tighter as tiles get bigger. A floor that would be fine for small mosaics may be too wavy for long porcelain planks.
The results get marked right on the floor. That map tells us whether a few spots need patching or whether the whole room needs a poured leveling layer.
Grinding, patching and pouring
High spots on concrete are ground down. Low spots that are small and shallow can be filled with a trowel-applied patch. When the dips cover a large area, a self-leveling underlayment is the usual answer: a cement-based mix that is poured as a liquid and spreads out to a flat surface on its own.
Getting a good pour takes preparation. The slab is cleaned and primed so the leveler bonds instead of skinning over. Gaps along the walls and at floor openings are sealed, and dams of foam or wood keep the mix from running into the next room. Over a wood subfloor, most manufacturers call for reinforcing lath and extra steps, so we follow their instructions for that substrate. The leveler then cures for the time its maker specifies before tile can go on top.
Cracks and movement before leveling
A leveler fills low areas; it does not fix a slab that is still moving. Before pouring, we look at every crack. Fine shrinkage cracks with level edges are common and can usually be covered later with an uncoupling or crack-isolation membrane. A crack that has opened wide or has one side higher than the other suggests ongoing movement, and that needs to be understood first, because it will eventually show through any floor.
On a framed floor, a dip may come from a sagging joist rather than the subfloor surface. In that case the repair belongs under the floor, not on top of it.
How leveling changes height and edges
Every layer adds thickness. A pour that is shallow at one wall and deeper at another, plus membrane, mortar and tile, can raise the floor more than expected at certain doorways. We measure the neighboring floor at each opening and choose the trim once the build-up is known: a low reducer where the difference is small, a threshold or a reworked neighboring floor where it is larger.
In bathrooms and laundry rooms, the waterproofing membrane goes over the cured leveler, so it gets a smooth, clean surface to bond to. Water exposure and the room’s edges, such as a tub apron or an exterior door, are planned at the same time.
Grout joints on a well-prepared floor
A flat base lets the joints stay consistent. Rectified tiles with straight ground edges can be set with a narrow joint, while tiles with slightly uneven edges need a wider one, and neither should go below the manufacturer’s minimum. On a floor that was never leveled, installers often widen joints to hide edge differences, which is one more reason to correct the base first.
Where Lilburn homeowners ask about permits
Lilburn is in Gwinnett County. The City of Lilburn Business Services Department issues building trade permits, so homeowners whose project includes plumbing, electrical or structural work alongside the tile can ask that office whether a permit is needed.
Leveling allowances and the order of work
The work runs from removal of the old floor to grinding, patching or pouring, then membrane, layout lines, setting, curing, grouting and sealant at the perimeter. At the end we go over the layout and the movement joints and confirm the slab or subfloor shows no new problems.
Because the depth of a pour is only certain once the floor is bare, leveling is sometimes listed as an allowance with a clear unit, so you can see how the price changes if more or less material is needed. The estimate should also spell out exclusions, such as structural repairs under a framed floor. For bathroom projects that go beyond the floor, see our bathroom remodeling services in Lilburn.
Floor leveling questions in Lilburn
What is self-leveling underlayment, and when does a floor need it?
It is a cement-based mix poured as a liquid that spreads out to a flat surface before it hardens. It is used when dips or uneven areas cover too much of the floor to fix with spot patching. Larger tiles make it more likely to be needed, because they show unevenness more clearly. The surface is cleaned and primed first, and the pour cures before tile goes down.
Can self-leveler be poured over a wood subfloor?
Often, yes, but it takes more preparation than a slab. The subfloor must be stiff and well fastened, gaps are sealed so the liquid does not leak through, and most manufacturers require reinforcing lath and a specific primer over wood. If the floor flexes or a joist sags, that has to be corrected underneath first, since a poured layer cannot stiffen a bouncy floor.
Why would an estimate list floor leveling as an allowance?
Because the exact amount of material depends on what the floor looks like once the old covering is removed. An allowance sets a quantity and a unit price, so you can see in advance how the cost moves if the dips turn out deeper or shallower than expected. The final amount is then based on what was actually used, documented in writing.
