Concrete & Masonry Work

Structural work done to spec: footings, block, slabs, and repairs.

Footings, slabs, tie-beams, CMU walls, columns, steps, seating walls, and spalling repair. Concrete and masonry are unforgiving: rebar placement, cover, mix, and curing decide whether the work lasts thirty years or cracks in three.

Typical timeline

3 days–4 weeks

Typical investment

Quoted per scope; small slabs and pads commonly $2,500–$12,000

How we approach it

Concrete work built to last the life of your home

Concrete and masonry are unforgiving. Whether it's a structural slab, a CMU block wall, or a repair to a balcony, the quality of the rebar placement, the concrete mix, and the curing process determine if it lasts thirty years or cracks in three.

We specialize in structural concrete and masonry that meets or exceeds code requirements. We handle footings, tie-beams, block walls, equipment pads, and spalling repairs, always working from engineered plans where structural loads are involved.

Our work is finished to suit the final use, whether it's a smooth slab for a patio or a decorative wall. We build it once, and we build it right.

Example project

Structural balcony repair restored safety and integrity

Hollywood, FL3 weeks

The challenge
A balcony showed significant spalling with rusted rebar exposed, raising safety concerns about structural integrity.
What we did
We shored the balcony, removed the compromised concrete, treated and replaced the damaged steel reinforcement, and re-poured with high-strength structural concrete.
The result
The balcony is fully structurally restored and safe, and the finish matches the original concrete exterior.

Illustrative example based on typical jobs of this type.

Client feedback

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.”
Andre & Sofia P. · Coral Springs, FL · Full backyard renovation
“We turn over rental units on tight deadlines. They have never once missed a make-ready date, and their punch lists are cleaner than anyone we've used.”
