Insulation contractor in Dallas, TX - attics sealed first, then insulated
Steadfast Dallas Spray Foam Insulation is an insulation contractor in Dallas, TX. We seal the gaps in your attic, crawl space and walls, then add blown-in or spray foam insulation, and we take out old insulation that's past saving.
Dallas houses, from crawl spaces to long attics
Dallas has just about every kind of house, and each one hands us a different attic. Older pier-and-beam homes sit raised on short piers over a crawl space, so drafts and cold floors come up from below as often as down from the attic. Mid-century ranch houses tend to have one long, low attic that's easy to walk in the middle but tight at the edges, which is right where the insulation runs thin. Newer two-story houses put a lot of house under one roof, with ductwork running through the attic. And there are plenty of duplexes and small apartment buildings, the kind I spent years crawling through for a property management company.
We see the same mix of houses in Grand Prairie and Irving, so the work doesn't change much at the city line. On a Dallas job, the price mostly comes down to the size of the attic or crawl space and what's already in it, and the schedule turns on whether old material has to come out first and whether the city wants a permit. You get the number for your house at the estimate. In an older house, the job usually starts with what's under the old insulation, not with piling more on top.
What Dallas attics and crawl spaces usually need
Most Dallas calls start with the same few complaints, like a hot room upstairs, drafty bedrooms, cold floors or a power bill that keeps climbing. Here's what we usually find behind them.
Older houses here often have a few inches of insulation that's settled flat, so we measure what's up there before suggesting anything.
Eave vents get buried under blown insulation more often than you'd think, and an attic that can't breathe shows it as moisture in the framing.
The room over the garage runs hot because its floor sits over a garage nobody heats or cools, so that floor needs insulation too.
Rentals and duplexes need the work done around tenants, with access, dust and the hatch planned out before the crew shows up.
You can't tell which of these you've got from the hallway, so I come out, climb up and look before I write anything down.

Insulation services for Dallas homes and buildings
Spray foam insulation
On a lot of Dallas houses the ductwork runs through the attic, and spray foam under the roof seals and insulates at once, so those ducts sit inside.
Attic insulation
Attic work is what we're best known for in Dallas, from hot rooms over the garage to drafty bedrooms, and it starts with what's already up there.
Blown-in insulation
Blown-in insulation, loose fill blown through a hose, is how we top up most Dallas attics after sealing, with the edges as deep as the middle.
Home insulation
When a Dallas house feels drafty all over, I check the attic, walls and crawl space at the estimate, so we fix the worst spots first.
Insulation removal
We pull out old insulation soaked by roof leaks or full of droppings, which we find in plenty of older Dallas attics, before anything new goes in.
Crawl space insulation
Pier-and-beam houses in Dallas sit over a crawl space, and insulating under the floor is usually what fixes cold floors in the rooms above.
Wall insulation
Older Dallas houses often have empty or half-filled wall cavities, and we can fill them through small holes so the finished walls stay in place.
Air sealing services
Air sealing, closing the gaps before insulating, is the step that gets skipped on a lot of Dallas houses, and it's why new insulation can still feel drafty.
Basement insulation
Basements are rare in Dallas, but when a house or building has one, we insulate the walls so the room below ground is easier to keep comfortable.
Closed-cell foam insulation
Closed-cell foam, a dense foam that blocks moisture, fits Dallas crawl spaces and other spots where damp is the real problem, not just heat.
Open-cell foam insulation
Open-cell foam is softer and costs less than closed-cell, and it suits Dallas attic rooflines where the goal is sealing air and quieting the house.
Commercial insulation
Offices, shops and apartment buildings in Dallas get the same seal-first order, scheduled around tenants, which is where I learned the trade in the first place.
Crawl space vapor barrier
A vapor barrier over the dirt under a pier-and-beam Dallas house keeps ground moisture off the floor framing and the insulation above it.
Vapor barrier installation
Where moisture could reach insulation in a Dallas wall, floor or basement, we install a vapor barrier, and we leave it out where it would trap damp instead.
Attic air sealing
Before any insulation goes into a Dallas attic, we seal the gaps around can lights, pipes and the hatch, so the new layer isn't fighting a draft.
Retrofit insulation
In an older Dallas house that's already lived in, retrofit work adds insulation to the attic, walls and floors without tearing out finished rooms.

Why Dallas homeowners and landlords call us
I started this business in 2017 after years of cleaning up insulation jobs done in the wrong order. Here's how we work on Dallas houses and rentals.
Sealed first, insulated second
We fix leaks, seal gaps and pull out ruined insulation before anything new goes down. Insulation laid over a problem doesn't solve it. It just tucks it in.
Estimated and checked by me
I'm the one who climbs into your attic and writes the estimate. Our crew does the install, and I check the work before we call it done. Licensed and insured. Satisfaction guaranteed.
No work you don't need
If what's up there is doing its job, I'll tell you and leave, because I'd rather lose a sale than sell you work you don't need. Call (214) 706-4099 to set up a visit.
Insulation questions from Dallas homeowners
Do I need a permit to insulate my attic in Dallas?
Possibly, so we check with the city's building office before we start. In Dallas the building official issues a master permit for work that alters, repairs, replaces or installs a structure or building service equipment, and when your job needs one, we handle the application and the inspections. The city's building inspection FAQ lists some work that needs no permit, but the city calls that list partial.
How do I apply for a building permit in Dallas?
All Dallas permits are submitted through the city's DallasNow system. If your insulation job needs one, you don't have to file it yourself, because we handle the application and the inspections with the city.
How do I insulate a house in a Dallas historic district?
Inside the house the job runs the same, but in a city-designated historic district any exterior work needs an approved certificate of appropriateness before it starts. Most insulation work happens in the attic or crawl space. If something on your job would change the outside, such as filling walls through holes in the siding, we sort that out with the city first.
Can my insulation contractor move the wiring in my Dallas attic?
No, in Dallas electrical work has to be done by a licensed electrician. A homeowner can do the work on their own home after proving their knowledge and expertise to the Chief Electrical Inspector. If I find wiring that looks wrong, I'll show you, and we wait until it's fixed, because insulation over bad wiring just hides it.
How much does it cost to insulate an attic in Dallas?
Your number comes from the on-site estimate, because what has to happen before new insulation goes in moves the price more than anything. Pulling out soaked or dirty insulation and sealing a lot of gaps both add to it. Foam costs more than blown-in because it seals and insulates at once, and in most Dallas houses sealing the gaps and topping up loose fill wins, unless the ductwork runs through the attic.
What hours can contractors work on a house in Dallas?
For permitted projects, the city's residential guide advises working only during approved construction hours, which are 7 a.m. to 7 p.m. Monday through Friday and 8 a.m. to 6 p.m. on Saturday. If you're a landlord lining up tenant access, those are the hours to plan around.
