Insulation Contractor in Carrollton, TX - Cooler Upstairs Rooms and Sealed Attics
Steadfast Dallas Spray Foam Insulation is an insulation contractor working in Carrollton, TX. We seal the gaps in your attic first, then add loose fill or spray foam, and we insulate walls and crawl spaces too.
Carrollton houses and the attic calls we get
Carrollton calls sound a lot like the ones we get across Dallas. An upstairs that runs hot, a room over the garage nobody wants, cold floors, a power bill that keeps creeping up. It's the same work we do in Arlington and Richardson, and it usually starts in the attic.
The houses here run from single-story homes where the old fill has settled thin to two-story houses with a bedroom over the garage. Your price turns mostly on how much old material has to come out and how much sealing the attic needs, and the schedule turns on how easy the attic is to reach and whether the city wants a permit. Your own figure comes in the estimate I write after I've been up there. On these houses, how low the roof sits, how the garage room is framed and what's already in the attic decide where our crew can work and what goes down first.
What we find in Carrollton attics and crawl spaces
Most of what I find in Carrollton houses comes from how they were built and what's piled up in the attic since. These are the conditions that decide the job.
Many houses here keep the ductwork in the attic, so a thin, leaky attic warms the cooled air before it reaches a room.
Two-story houses usually run hot upstairs, because the bedrooms sit right under an attic floor that's often thin or unevenly covered.
Older fill settles over the years, and we often find it piled deep in the middle and thin at the edges, which is backward.
Houses here that sit over a crawl space instead of a slab often have cold floors, because outside air moves under them freely.
I'd rather look at your attic before telling you what it needs, because those conditions decide whether you need sealing, a top-up, removal or foam.

Insulation services for Carrollton homes
Spray foam insulation
Spray foam seals air while it insulates, which helps in attics full of ductwork and the tight framing around garage rooms. I'll tell you when it's worth it.
Attic insulation
This is where most of our calls start. We check what's already up there, measure how many inches you have, and seal gaps before adding anything on top.
Blown-in insulation
Blown-in insulation, loose fill blown through a hose, is how we top up a thin attic floor, keeping it even out to the eaves without burying the vents.
Home insulation
For a house that's drafty upstairs and cold on the floors, I look at the attic, walls and crawl space together and tell you what to do first.
Insulation removal
When the old insulation is soaked from a past leak or full of droppings, we take it out first, because new material on top just hides the problem.
Crawl space insulation
Cold floors over a crawl space usually mean the floor has thin insulation or none. We insulate under the floor and seal the gaps where pipes come through.
Wall insulation
Outside walls that feel cold to the touch often have little inside them, so we fill them through small holes that get patched afterward.
Air sealing services
Air sealing, closing the gaps before we insulate, isn't just an attic job. We seal around plumbing walls, the room over the garage and the crawl space edge.
Basement insulation
Not many houses we see here have a basement, but when yours does, we insulate the walls and seal the rim where the framing sits on the foundation.
Closed-cell foam insulation
Closed-cell foam, a dense foam that blocks moisture, is what we use in crawl spaces and along rim joists, where damp air and tight space both matter.
Open-cell foam insulation
Open-cell foam is the lighter, softer kind, and it's what we usually spray under the roof deck when the ductwork and air handler live in the attic.
Commercial insulation
Landlords and property managers call us for rental buildings, offices and shops, and we plan the work around tenants so the building keeps running.
Crawl space vapor barrier
Bare dirt in a crawl space lets moisture rise into the floor framing, so we cover it with heavy plastic sheeting and tape the seams.
Vapor barrier installation
A vapor barrier in the wrong spot traps moisture instead of stopping it, so we work out which side of the wall or floor it belongs on.
Attic air sealing
We seal around can lights, pipes, wiring holes and the attic hatch before anything goes on top, so the new insulation isn't fighting a draft.
Retrofit insulation
Retrofit work means insulating a house that's finished and lived in, so we plan around your furniture, your schedule and, in rentals, the tenants.

Why Carrollton owners and landlords call us
Homeowners call us, and so do landlords and property managers who need the work done without a fuss. Here's what you get either way.
Sealing first, insulating second
I spent years in rental buildings cleaning up insulation laid over leaks and bad wiring. If something up there needs a roofer or an electrician, I tell you before we cover it, then we seal and insulate.
I quote it and check it
I'm the one who comes out, looks at the job and writes the estimate. Our crew does the install, and I check the work before we call it done.
We'll say when it's not needed
We're licensed and insured, and we've been doing this since 2017. Satisfaction guaranteed. If your attic doesn't need more, I'll say so. Call (214) 706-4099 to set up a visit.
Carrollton insulation questions we hear
Do I need a permit to insulate my attic in Carrollton, TX?
Carrollton's residential permit list doesn't name insulation, but the city says that list isn't complete, so the answer for your job comes from Building Inspection, and I check with them before we start. The city requires permits to alter or repair a building and to replace any electrical, gas, mechanical or plumbing system, so a job that swaps out ductwork or wiring along the way can need one. When it does, we handle the application and the inspections with the city, and you can reach the office yourself at 972-466-3225.
Who has to register as a contractor with the City of Carrollton?
Anyone other than the homeowner who does homebuilding, plumbing, mechanical or electrical work on a house in Carrollton has to be registered with the city. Contractors register through CityServe, the city's online portal, and the city notes that homeowners can do all the work on their own homestead. If your insulation job includes duct or wiring changes, that part falls under the registration rule.
How do I book a building inspection in Carrollton?
You request it on CityServe, the same portal used for permits. Inspections run 7:00 a.m. to 4:30 p.m. Monday through Thursday and 7:00 to 11:00 a.m. on Friday, and a request made before 7:00 a.m. gets an inspection the same business day. On jobs where we pull the permit, we book the inspections.
How much does attic insulation cost in Carrollton, TX?
I can't give you an honest number until I've seen your attic, because the price turns on what's already up there and what has to happen before new insulation goes in. The big swings are how many inches you have now, whether soaked or dirty material has to come out, how many gaps need sealing and whether you go with foam or loose fill. Foam costs more because it seals air while it insulates, and sealing the gaps and topping up loose fill usually comes out ahead unless your ductwork lives in the attic.
How long does attic insulation take, and do we have to leave the house?
With loose fill you can usually stay home, but spray foam means clearing out until the foam maker's re-entry time, the point when it's safe to come back in, has passed. How long our crew is up there depends mostly on prep, any removal and how much sealing your attic needs. I'll tell you what to plan for, kids and pets included, when I write the estimate.
What causes a hot room over the garage in a Carrollton house?
Usually it's an unheated garage under the floor, attic space right beside the walls and open gaps where the two meet, so the room picks up heat from below and from the side. We seal those gaps, insulate the garage ceiling under the room and cover the short attic walls beside it. On some of these rooms foam is the better call, because the spaces are too tight to lay loose fill well.
