Why do rigid floorings like LVP and engineered hardwood require a perfectly flat subfloor?
+
Unlike carpet or vinyl sheet goods that flex and conform, rigid planks sit on top of the subfloor and transfer every imperfection directly to your foot and ear. Even a 1/4" low spot over 3 feet creates visible gaps under planks, causes the floor to rock when you walk on it, and forces planks to cup or crack as they try to bridge the void. Engineered hardwood is especially sensitive because its plywood core can't flex without breaking the veneer. LVP manufacturers explicitly void warranty if subfloor variance exceeds 3/16" over 10 feet—that's not a suggestion, it's a hard install requirement.
What's the difference between self-leveling concrete and patching compound, and which do I need?
+
Self-leveling concrete is a poured, fluid product that fills and hardens to create a perfectly flat plane—ideal for large areas of concrete slabs with multiple low spots or severe unevenness. Patching compound is thicker, applied by trowel, and better for isolated high spots, small voids, or plywood subfloors where you need precision rather than full coverage. Mak Floors assesses your subfloor during the pre-install inspection and specifies whichever product (or combination) will meet the 3/16" flatness standard. Both require 24 hours of cure time before flooring installation can begin, so plan accordingly.
Is floor leveling really worth the extra cost, or can I just install over an uneven subfloor?
+
Leveling adds $2–$5 per square foot upfront, but it's the only way to unlock the full lifespan and warranty protection of quality LVP or engineered hardwood. Install over an uneven subfloor and you're guaranteeing callbacks, creaking, premature wear, and potential voided warranty from the flooring manufacturer—costs that dwarf the leveling expense. For a 1,500 sq ft home, leveling runs $3,000–$7,500; replacing failed flooring in 3 years costs $15,000–$25,000. It's insurance, not optional.
How long do self-leveling compounds and patches last once installed?
+
Self-leveling concrete and patching compounds are permanent once cured—they don't degrade, crack, or require maintenance unless the underlying structural issue (like ongoing slab settlement) continues. The lifetime is tied to your flooring and substructure, not the leveling layer itself. Mak Floors backs all leveling work with our lifetime installation workmanship warranty, so if any component fails due to prep, we make it right at no charge. The real risk is slab settlement or water damage affecting the subfloor after install—a structural issue, not a leveling failure.
Are older homes in Roseville and Placer County more likely to need subfloor leveling?
+
Absolutely. Homes built in the 1980s–2000s on concrete slabs often have minor settling and clay-layer movement that creates valleys; older plywood subfloors have warped from moisture and age. Sacramento's hot, dry summers and occasional wet winters accelerate wood movement and concrete micro-cracking. Slab-on-grade homes are especially common in this region, and they're the most prone to flatness issues. If you're installing premium LVP or engineered hardwood in a Roseville or Placer County home, expect subfloor leveling to be part of the job—Mak Floors factors it into pre-install assessment and quotes transparently so there are no surprises.
