Insulation in Jacksonville & Northeast Florida

Stop paying to cool the ground.

Money is being wasted on your electricity bill by heating and cooling your crawlspace. Soiled, sagging insulation also holds moisture against the wood. We remove the old material and install insulation that stays dry and does its job.

How the system works

A sealed, conditioned crawlspace

Not to scale · sized to the space
1Bare Florida ground gives off moisture all year. Half the air on your first floor comes up through it.
2A reinforced vapor barrier covers the floor and runs up the walls, seams taped and fastened.
3Vents get sealed and the walls insulated. A vented crawlspace in Florida just imports humid air.
4A dedicated dehumidifier holds the space dry, which is what stops mold and wood rot from coming back.
5Where water collects, a sump carries it out before it reaches the liner.

Where you live changes the job

Four kinds of ground, four versions of this job

Northeast Florida has four distinct ground conditions, and each one changes how we size and sequence this work. Your town page has the specifics.

  • Barrier islands and the Intracoastal

    Full encapsulation with a sealed liner and dehumidifier, stainless or coated fasteners, and a sump where the water table reaches the crawl floor in storm season.

  • St. Johns River and tidal creek lowlands

    Drainage first: a perimeter French drain and a sump sized for the volume, then a sealed liner and dehumidifier so the wood can finally dry out.

  • Pine flatwoods and hardpan

    Vapor barrier or full encapsulation with a dehumidifier to break the humidity cycle, plus grading, downspout extensions and a French drain where water perches against the foundation.

  • Karst and clay uplands

    Moisture control with a sealed liner and dehumidifier, drainage where clay holds water against the foundation, and an honest assessment of any pier or block movement before anything is sealed.
