Insulation Installation

Lower cooling bills and a quieter, drier house.

In Florida, insulation is a humidity and air-sealing job as much as a temperature job. We air-seal penetrations first, then insulate attics, walls, and garages to the right R-value so your AC stops fighting the attic all afternoon.

Typical timeline

1–3 days

Typical investment

Attic upgrades commonly $2,200–$8,500

How we approach it

Stop cooling your attic and start cooling your home

In South Florida, insulation is a vital part of your home's thermal and moisture management. If your attic is poorly insulated, your AC unit spends all afternoon fighting the heat coming through the ceiling, which leads to higher bills and more humidity inside.

We assess your attic and walls to determine the right insulation solution. Our work starts with air sealing major penetrations, then adding high-performance blown-in insulation or batts to reach the proper R-value for our climate.

The result is a more consistent indoor temperature, a quieter home, and an AC system that can finally handle the job it was built for without running overtime.

Example project

Attic insulation upgrade reduced cooling load by 25%

Boca Raton, FL2 days

The challenge
A home with a large attic and poor insulation was struggling to cool during the afternoon, leading to a constant cycle of AC repairs.
What we did
We sealed air leaks in the attic and installed a fresh layer of blown-in fiberglass insulation to bring the R-value up to current standards.
The result
The homeowner noted a significant reduction in the cooling load and a much quieter indoor environment, and the AC unit finally stops running after the setpoint is reached.

Illustrative example based on typical jobs of this type.

Standards we hold

  • We seal major air penetrations before adding insulation
  • Attic ventilation is checked and protected during install
  • We document R-value before and after the job
  • Installation is inspected for even distribution and thickness
  • Can lights and other fixtures are properly dammed to prevent fire hazard

On the job

What goes on above the ceiling

Blown-in attic insulation

Depth brought up to spec across the whole attic; thin or uneven coverage is why the AC never keeps up.

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
