Request an estimateArlington: older attics, newer subdivisions
Arlington is a big city with a lot of single-family streets. The houses run from older neighborhoods with a few decades behind them to newer subdivisions out toward Mansfield. The calls we get here sound like the ones from all around Fort Worth: a hot upstairs, a drafty bedroom, a room over the garage nobody wants to sit in, a power bill that keeps going up. Some come from property managers with rentals or small offices.
In the older houses, the attic usually holds a few inches of flattened insulation with open gaps around the lights and the hatch, so the work starts with sealing and sometimes with clearing out what's there. In newer two-story houses, the ductwork often runs through the attic, and that changes whether foam or loose fill is the better choice.
Working in Arlington: permits, schedule and price
Home permits in Arlington go through the city's Planning and Development Services department. Its list names residential, electrical, mechanical and plumbing work, among others, but not insulation by name. So before your job starts, I check with that office about what it needs, and we take care of any permit and inspection on our end. If one is needed, it gets sorted before we start, so it's part of how we set the date. We're fully licensed and insured, and you're welcome to ask about that before anyone climbs into your attic.
The price mostly comes down to what I find up there: how big the attic is, how many inches are already down, whether any of it is wet or dirty enough to come out, how many gaps need sealing, and whether you go with foam or loose fill. The schedule turns on the same things, plus anything that has to be fixed first, like a roof leak. Your own figure comes from the estimate I do on site. It's the same way we work next door in Grand Prairie and back home in Fort Worth.
Services in Arlington, TX
Attic insulation
A lot of older Arlington attics have only a few inches of flattened insulation left. We check what's up there, seal the gaps and bring the attic insulation up evenly, edges included.
Attic air sealing
Drafty rooms usually trace back to gaps around can lights, pipes and the attic hatch. We seal those first, so new insulation isn't fighting a draft.
Insulation removal
Some older Arlington attics hold insulation soaked by an old leak or full of droppings. We pull it out first, because new material laid on top keeps the problem.
Spray foam insulation
When ductwork runs through the attic or the room over the garage stays hot, foam often fits best. We spray it there and use loose fill elsewhere.
Wall insulation
Some older houses here have very little in the exterior walls, so the rooms along them never feel right. We fill the wall cavities through small holes and patch them.
Commercial insulation
Property managers and business owners here call about offices and rentals that won't hold a steady temperature. We check the building first and tell you what needs fixing before insulation helps.

Frequently asked questions
How much does it cost to insulate an attic in Arlington, TX?
There's no single price, because it turns on what your attic needs, so your number comes from the on-site estimate. Sealing the gaps and topping up loose fill usually costs less and does the job well. Foam costs more because it seals air while it insulates, and I'd point you to it mainly when the ductwork lives in the attic.
How do I apply for a building permit in Arlington online?
You apply through the city's online permit portal, where each permit type has its own application. The first step is finding the type that matches your project. If you'd rather call or go in, the department's office is at City Hall, 101 W. Abram St, 2nd Floor, and its number is (817)459-6502. For an insulation job, we check with the city and handle any permit ourselves, so that part is on us.
How long does attic insulation take in an Arlington house?
Putting in the insulation is usually the quick part. Most of the crew's time in your attic goes into prep: sealing gaps, clearing out bad material and keeping the vents along the eaves open so the attic can breathe. I'll tell you what to expect for your house at the estimate, once I've seen what's up there.
Do we have to leave the house during spray foam insulation?
For spray foam, yes. You, the kids and the pets stay out until it's safe to come back, and I give you that re-entry time before we start. With blown-in insulation, which is loose fill blown through a hose, most people stay home and just keep clear of the hatch while we work.
What causes a hot upstairs in a two-story house in Arlington?
Usually it's an attic with thin insulation and open gaps, so heat from the attic gets into the rooms below. Coverage that's deep in the middle and thin at the edges, buried eave vents and ductwork running through the attic all make it worse. Those are the first things I check.
Should I fix a roof leak before insulating my attic?
Yes, get the roof fixed first. Insulation laid over a leak or wet wood soaks up the water and won't do much for you. If I find a leak or damp framing at the estimate, I'll tell you plainly, and we'll schedule the insulation after the repair.
