Flooring Installation & Replacement

Flat, level, quiet floors, because the prep is where floors fail.

Tile, large-format porcelain, luxury vinyl plank, engineered wood, and natural stone. Most flooring complaints (lippage, hollow tiles, squeaks, cracked grout) come from skipped substrate prep. We measure flatness, grind and self-level, and use the correct membrane and mortar for the material.

Typical timeline

3 days–2 weeks

Typical investment

Typically $6–$22 per square foot installed depending on material and prep

How we approach it

The difference is in the substrate preparation

In South Florida, flooring failure is almost always caused by what is underneath the material. Between concrete slabs that hold moisture and uneven surfaces that cause tiles to crack, the installation itself is only half the job. We focus on the prep work that other contractors ignore.

Whether you are installing large-format porcelain, luxury vinyl plank, or engineered wood, we start by measuring the flatness of your slab. We grind down high spots and use self-leveling compounds to ensure your floor is perfectly flat, which prevents the hollow sounds and 'lippage' that ruin a new installation.

We also address moisture. Our humid climate means that vapor can rise through a concrete slab and destroy wood or cause tile grout to fail. We use the correct moisture barriers and crack-isolation membranes on every project to ensure your floor stays perfect for decades.

Example project

Seamless large-format tile installation

Fort Lauderdale, FL10 days

The challenge
A 2,000-square-foot home with an extremely uneven slab and three different types of existing flooring to be removed.
What we did
We performed a full-home slab grind and used 40 bags of self-leveling compound to create a flat surface. We installed 30x60 porcelain tiles with 1/16-inch joints.
The result
The floor is perfectly flat with zero lippage, and the large-format tile creates a stunning, continuous look that flows through the entire house.

Illustrative example based on typical jobs of this type.

Standards we hold

  • We check slab flatness with a 10-foot straightedge on every job
  • Moisture testing is performed before any wood or LVP install
  • We use premium thinset with high polymer content for better bonding
  • Crack isolation membranes are standard under all tile installations
  • Expansion gaps are strictly maintained at all walls and transitions

Referred, again and again

“They gutted and rebuilt two bathrooms and our kitchen while we lived in the house. Every day the site was clean, every question got answered the same day, and the final number matched the estimate.”
Daniel R. · Fort Lauderdale, FL · Kitchen + 2 bathroom remodel
“We had water damage behind a wall that two other contractors misdiagnosed. 12X found it in an hour, handled the drying, rebuilt the drywall, and dealt with the insurance paperwork.”
Melissa T. · Hollywood, FL · Water-damage restoration
“Pavers, a pergola, an outdoor kitchen, and turf, done in five weeks and permitted properly. Our backyard is the reason we stopped talking about moving.”
