Have your crawl space checked first
I go under the house and check vents, ducts and any gas equipment before suggesting anything.
Request an estimateWhy are my floors cold, and will crawl space insulation help?
Crawl space insulation in Fort Worth seals and insulates the space under your house, either along its walls or under the floor above, so the rooms over it stop losing heat through the floor.
Most people call because the floors are cold, a room over the crawl space never feels right, or the power bill keeps going up. The price moves with how big the space is, whether we insulate the walls or the floor, which material fits, and whether old wet insulation has to come out first through insulation removal. The schedule mostly turns on what's down there, because a leak, wet wood or a gas appliance gets dealt with before any insulation goes in. When I come out to look, you'll get a figure for your own house. We're based in Fort Worth and work in many of the cities around it.
How we handle crawl space insulation
I start under the house, because whether we insulate the crawl space walls or the floor above depends on whether the space is vented and what's down there. I look at the ducts and any furnace or water heater that burns fuel first, then at damp spots, wet wood and old insulation that needs to come out. Once that's settled, our crew seals the gaps where pipes and wires come through, installs the insulation and cleans up after. If we close the vents, that comes with a plan for keeping the space dry, and I'll explain that plan before we start.
Crawl space work often ties into the rest of the house. If the floors feel better but the outside walls still run cold, wall insulation is usually the next step, and our air sealing services close the gaps that let air move between floors, walls and attic so the new insulation isn't fighting a draft.
Crawl space insulation in Fort Worth: foam, permits and what we find
If the plan calls for foam, most codes want a thermal or ignition barrier over it, usually drywall, though some foam products are made and tested to reduce those risks. The foam we pick gets checked with the city to confirm it meets code here. I won't guess at whether your job needs a permit, so before work starts we ask the city's building office what the job needs and take care of any permit and inspection on our end.
A lot of the older houses we see here sit on pier and beam, with ducts and sometimes a water heater under the floor. We find the same setup on jobs in Haltom City and Burleson, so the first look goes the same way there.
Why call us for crawl spaces
I do the estimate myself
I come out, go under the house and give you the estimate myself, then I run the work alongside our install crew. You hear the plan from the person who'll be there while it gets done.
Trained on a Fort Worth crew
I left an office job to learn insulation on a Fort Worth crew and started this business in 2020. I'd rather tell you to fix a leak or a wet spot first than sell you insulation that won't help.

Frequently asked questions
What is the best way to insulate a crawl space in Fort Worth, the walls or the floor?
Insulating along the crawl space walls is considered best practice in any climate, though in some houses the floor above works better as the line between inside and out. One cost guide suggests the walls when the space is unvented or has HVAC ducts in it, and the floor when it's vented. That's why the estimate starts under the house, not at the kitchen table.
How do I close my crawl space vents safely?
You close a vented crawl space with a full plan, not just by blocking the vents, because sealing the openings alone can raise moisture down there. If a gas furnace or water heater in the crawl space draws its air naturally, sealing only the vents can create a deadly situation, so that equipment gets handled first. A sealed crawl space also needs a way to dry out, and one of the better ways is a small amount of conditioned air from your heating and cooling system. Depending on conditions, closing it slowly can be best, since fast drying can damage wood finishes in the rooms above.
How much does crawl space insulation cost in Fort Worth?
Insulating a crawl space in Fort Worth usually costs about $1,500 to $6,800 per job, and that's the going rate around here, not our price. Your own figure comes from the estimate, after I've been under the house and seen what it needs.
Can I insulate my crawl space myself?
You can, but air sealing and insulating a crawl space is generally rated a moderate to difficult do-it-yourself project, with real benefits when it's done right. The hard parts are the ones that are tough to undo, like closing vents around gas equipment or picking walls over floor, so if you'd like us to look first, call (817) 349-3679.
What causes moisture problems in a vented crawl space?
In mixed or hot-humid climates, crawl space vents tend to let in more moisture than they let out, so the space gets damper, not drier. That moisture condenses on the cooler wood floor framing, which can lead to mold and wood damage over time. If you're seeing damp wood or smelling something musty, that needs a plan before any insulation goes in.
Are fiberglass batts a good choice for a crawl space in Fort Worth?
One cost guide calls fiberglass batts the most common choice but also the most problematic in vented crawl spaces. The guide says they come loose over time and soak up moisture, which cuts how well they insulate and can lead to mold. In a sealed crawl space, rigid foam board on the inside of the walls can give ducts an insulated, sealed space and, in humid climates, help keep condensation off the floor joists.

Wall insulation
If the rooms above still feel cold or hot after the floor is done, the outside walls are often the next place heat slips out of the house.
Air sealing services
Small gaps around pipes, wires and the attic hatch let air move through the whole house, and closing them helps any insulation you add do its job.
