Why is my Conroe slab uneven if the house was built level?

Because the soil under it moves. Clay-heavy ground in this area expands when it is wet and contracts through a dry summer, and thirty years of that cycle leaves a slab that no longer matches the day it was poured. It is normal here rather than a defect. What matters is measuring it before choosing an installation method, since a floating floor over significant variation will telegraph and eventually separate at the joints.

How much self-leveling will my floor need?

Nobody can tell you over the phone, and that is the point. We put a straightedge and a laser across the floor at the measure and find the actual high and low points. Some 1990s Conroe houses need nothing; some need several hundred dollars of compound across a great room. Either way you get the number in writing before we start, rather than a change order once the carpet is up and the crew is standing there.

What luxury vinyl plank & laminate involves in Conroe

This is the single most common job we run anywhere in our service area: a 1980s or 1990s Conroe house on slab, original builder carpet in the living areas and 12x12 ceramic in the wet rooms, both at end of life, and the owner wants continuous plank throughout the downstairs. We do several of these a month and the variable is never the plank. It is the slab.

Slabs poured in this area in that era sit on soil with a high clay content that shrinks and swells dramatically between a wet spring and a dry August. Thirty years of that cycling leaves elevation differences that were not there when the house was built. We routinely measure half an inch of variation across a great room in these houses, and occasionally considerably more. A floating plank floor laid over that will telegraph every bit of it — you feel it underfoot, you see it in the light raking across the surface, and the joints eventually work loose at the peaks.

So we bring a straightedge and a laser to the measure, not just a tape. Where the variation is within tolerance we proceed normally. Where it is not, self-leveling compound goes down first and that is a real line item, not a formality. A bid that does not mention slab flatness in Conroe was produced by someone who did not check, and the difference will show up in your floor rather than in their quote.

The job we run most here

Full downstairs tear-out of original carpet and 12x12 ceramic in a 1990s subdivision house, with self-leveling across the great room before any plank is laid.

What it costs in Conroe

The plank work runs $5–$9 installed. Self-leveling is quoted separately by the bag once we have measured the actual variation — on a 1980s or 1990s Conroe slab, budget for some. Anyone quoting this town without checking flatness is quoting a different job than the one you have.
