Insulation Contractor in Mesquite, TX - Cooler Upstairs and Fewer Drafts
Steadfast Dallas Spray Foam Insulation is an insulation contractor working in Mesquite, TX. We seal attic gaps, add or replace insulation in attics, walls and crawl spaces, and spray foam where it earns its cost.

Mesquite houses as we see them on the job
Mesquite sits just east of Dallas, and most of our calls here come from neighborhoods of single-family houses. A lot of them are older one-story brick homes mixed in with newer two-story houses, and plenty are rentals, so we hear from landlords and property managers about as often as homeowners. The calls look a lot like the ones we get next door in Rowlett and up in Richardson.
Those older one-story houses usually have a low attic and whatever insulation went in years ago, so I check for water stains, droppings and wiring problems before we decide what stays and what goes.
Mesquite attics and what we usually find there
Most of what we fix in Mesquite isn't a missing layer of insulation. It's work done in the wrong order, with old material left in place and gaps nobody sealed.
Older one-story houses often still have their original attic insulation, packed down over the years and thinnest at the edges, which is backward.
Second floors and rooms over the garage run hot upstairs, usually because air moves through gaps the last crew covered instead of sealing.
In rentals we often find insulation soaked from an old roof leak or full of droppings, and it has to come out before anything new goes in.
Earlier top-ups often buried the eave vents, so the attic stopped breathing and moisture started showing up in the roof framing.
What's up there now, what has to come out and how much sealing it needs set the price and schedule, and you get your own figure after I look.

Insulation services we do in Mesquite
Spray foam insulation
Spray foam seals air and insulates in one pass, so it makes the most sense in Mesquite attics where the ductwork and AC unit sit up there.
Attic insulation
When the upstairs runs hot or the power bill climbs, we measure what's already in your attic, seal the gaps, then bring it up evenly to the edges.
Blown-in insulation
Blown-in fiber, loose fill we blow through a hose, is the usual top-up for older Mesquite attics once the gaps are sealed and the eave vents kept clear.
Home insulation
For a whole-house look, I go through the attic, walls and floors over the garage and tell you which spots are worth fixing and which can wait.
Insulation removal
Old insulation that's soaked, flattened or full of droppings comes out first, because new material laid over it just covers up the problem.
Crawl space insulation
When an older house sits up over a crawl space and the floors run cold, we insulate under the floor so the rooms above stay warmer.
Wall insulation
Exterior walls in older Mesquite houses are sometimes empty, and we can fill them through small holes, or insulate open walls during a remodel.
Air sealing services
Drafty rooms usually trace back to gaps around pipes, wires, outlets and the attic hatch, and we close those first so the insulation isn't fighting moving air.
Basement insulation
Few houses we see in Mesquite have a basement, but when one does, we insulate the walls and seal where the framing meets the foundation.
Closed-cell foam insulation
Closed-cell foam, a dense foam that blocks moisture, goes where depth is short or damp is a worry, like the sloped ceiling of a room over the garage.
Open-cell foam insulation
Open-cell foam is softer and costs less than closed-cell, and it suits an attic roof deck when you want the ducts inside the sealed space.
Commercial insulation
For Mesquite landlords, property managers and small commercial buildings, we plan the work around tenants and business hours so the job gets done without a fuss.
Crawl space vapor barrier
A plastic sheet over the bare dirt keeps ground moisture out of the crawl space and off the floor framing, and we lap and tape the seams.
Vapor barrier installation
Where a wall, ceiling or garage room needs a vapor barrier, we put it on the right side of the insulation, because the wrong side traps moisture.
Attic air sealing
Before any insulation goes in, our crew seals the attic floor around can lights, plumbing stacks, wiring holes and the hatch, where upstairs drafts usually start.
Retrofit insulation
In an older Mesquite house that's lived in, we add insulation without tearing into finished rooms, working from the attic, the crawl space or small wall holes.

Why Mesquite homeowners and landlords call us
I started this business in 2017 after years of cleaning up bad attic work in rental buildings. I'd rather tell you a job isn't needed than sell you one.
Seal first, insulate second
That's the order we're known for in attics, because loose fill laid over open gaps just has air moving through it. We close the gaps around lights, pipes and the hatch before anything gets blown in.
I write it and check it
I come out to look at your house and write the estimate myself, our crew does the install, and I check the work before we call it done. Satisfaction guaranteed.
We check with the city first
We're licensed and insured, and before a Mesquite job starts we find out from the city's building office whether it needs a permit. Call (214) 706-4099 to set up a visit.
Mesquite insulation questions we hear most
How much does it cost to insulate an attic in Mesquite, TX?
Most of the cost comes down to which material you choose and whether the old insulation can stay. Foam costs more because it seals air and insulates at once, but sealing the gaps and topping up with loose fill usually wins unless your ductwork runs through the attic. Soaked or droppings-filled insulation has to be hauled out first, which adds to the job, and I'll give you your own figure on site.
Do I need a permit to insulate my attic in Mesquite, TX?
The city's permit list doesn't name insulation on its own, so we ask the Building Inspection division before we start rather than guess. That list does cover repairs, remodels, electrical and AC work, so if your job touches any of those, expect a permit, and we handle the application and the inspections with the city. You can also call Building Inspection yourself at 972-216-6212 with permit questions.
Can a homeowner pull their own permit in Mesquite?
Yes, if you own the house, live in it and have it homesteaded through the Dallas Central Appraisal District. Otherwise a licensed contractor pulls it, through the city's online permit system, and each trade pulls its own. When we do the work and it needs a permit, we take care of it so you don't have to.
How do I time insulation with a remodel in Mesquite?
Insulate after the inspection, not before, because the city requires permitted work to stay open and visible until its inspector approves it. So the wiring, plumbing or framing gets checked first, and the walls or ceiling get insulated after. It's the order I'd want anyway, since insulation over bad wiring just hides it.
How long does attic insulation take, and when can we go back inside?
It turns mostly on whether the old insulation has to come out first, and I'll give you a time when I write the estimate. With blown-in fiber you can usually stay home while we work. Spray foam is different, because everyone, kids and pets included, clears out while it goes in and comes back after the re-entry time, which is the wait the foam maker sets.
What causes the upstairs of a Mesquite house to run hot?
Usually it's air leaking up from the rooms below through gaps around can lights, plumbing and the attic hatch, plus insulation that's thin right at the edges over the outer walls. Adding more on top won't fix leaks it's sitting on. We seal those gaps, then even out the coverage so the edges get as much as the middle.
