Houses and rental homes across Mustang
Most of the houses we get called to in Mustang are brick homes in subdivisions built over the last few decades. A lot of them have the ductwork and furnace up in the attic, plus a room over the garage that never feels like the rest of the house. We're based in Norman and work across the Oklahoma City area, so we see the same kind of build in Newcastle and a different one in the older houses of The Village, where the attics are shallower and the insulation has had more years to settle.
Closer to the middle of town there are older houses and plenty of rentals, and their attics often hold a few layers from different owners. So I start by looking at what's already up there, how many inches, whether any of it got wet and where the air comes through, because those three things decide whether we top it up, seal first or pull it out, and that's most of what moves the price and the schedule.
Our services in Mustang, OK
In a lot of Mustang subdivision houses the attic floor is full of gaps you can't see from below, around can lights, plumbing vents and the pull-down hatch, and that's often why the upstairs runs hot. We seal those first, because insulation laid over an open gap is like wearing a sweater with the zipper down.
Plenty of attics here have some insulation, just piled deep in the middle and thin at the edges where the roof meets the walls, which is backward. We even it out with blown-in, loose fill sent through a hose, and keep the eave vents clear so the attic can still breathe.
When the furnace and ducts sit up in the attic, as they do in many Mustang houses, they're working in the roughest spot in the house. Spraying open-cell foam insulation on the underside of the roof pulls that space inside the insulation, and it's the one case where I'll usually pick foam over loose fill even though it costs more.
In older houses and rentals we often find insulation that was soaked by an old roof leak or packed with droppings, and blowing new material on top just buries the problem. We pull it out, clean up and make sure the cause is dealt with before anything new goes in.
Garage conversions, additions and remodels are common here, and an open wall is the easiest chance you'll get to insulate it properly. We fill the cavities and seal around outlets and pipes so the insulation isn't sitting there fighting a draft.
Most houses we see in Mustang sit on a slab, but some of the older ones have a crawl space, and that's usually where cold floors come from. We check for moisture first, then insulate and seal underneath so the floor stops feeling like a tile bathroom in the morning.

What happens when you call us about a Mustang house
Call or send us a message
Tell us what you've noticed, like a hot upstairs, a drafty hall or a power bill that keeps climbing, and we set a time for me to come out. Landlords and property managers can call about a rental, and we'll work out access with the tenants.
I walk the attic with you
I come out myself, go through the attic or crawl space, take photos and show you what I find before I suggest any work. You get it written up with the price, so you can compare it with anyone else's and decide without guessing.
We fix, seal, then insulate
A crew I've trained takes care of whatever has to come first, like pulling ruined insulation, then seals the gaps and puts in the new insulation. Sealing goes first because insulation over an open gap only slows a draft down instead of stopping it.
I check the finished work
Before we call it done, I check the work against what we agreed on and go through the photos with you. You'll know how many inches are up there now and why we sealed where we did, which helps you make sense of the next repair.
Mustang insulation questions answered
What do I need to apply for a building permit in Mustang, OK?
You apply to the city's Community Development Department with legible construction documents and the required fees, and the city wants floor plans for any renovation, remodel or new structure. The documents it asks for change with the size and scope of the work. Whether an insulation job needs a permit depends on what we're doing, so we check with the city before we start, and when one's needed we pull it or walk you through getting it.
How do I check a contractor's license in Mustang, OK?
Ask for their City of Mustang license, because the city's residential construction guide says every general contractor and subcontractor has to be licensed by the city, and the city won't issue a contractor a permit until their state and city licenses are current. The state doesn't license general contractors right now, but the Oklahoma Construction Industries Board licenses trade work, and plumbing, electrical and mechanical contractors must carry a $5,000 surety bond payable to the board and at least $50,000 in general liability insurance. If your job turns up wiring that needs changing, that part goes to a licensed electrician, and you can look them up on the board's site.
Which building codes apply to a house in Mustang, OK?
For houses, the code the city council adopted in late 2022 is the 2020 International Residential Code, the model code written for homes. A state rule that took effect September 14, 2026 makes the 2024 edition the minimum code for one- and two-family homes and townhouses across Oklahoma, and cities can change it only as state law allows. Which edition a permit gets checked against is one of the things we ask the city before we start.
Does insulation have to be inspected before drywall goes up in Mustang?
The city's residential construction guide says every system, fixture and improvement has to be inspected before it's covered, so on a remodel or an addition nothing gets closed up until the city has seen it. We plan the wall insulation around those inspections, so the wiring and plumbing behind it are passed before we fill the cavities and the drywall waits its turn.
How much does it cost to insulate an attic in Mustang, OK?
The price comes down to what's already in your attic, how much sealing it needs first and whether loose fill or foam makes sense, so I don't put a number on it until I've been up there. Old material that's soaked or full of droppings has to come out before anything new goes in, which adds to both the cost and the schedule. Foam costs more because it seals while it insulates, and I usually point people to sealing the gaps and topping up loose fill unless the ductwork lives up there. Your written estimate is where your own figure comes from.
How long do I have to stay out of the house after spray foam insulation?
You stay out until the foam maker's re-entry time, the wait before it's safe to come back inside, has passed, and we tell you that time before the job is booked so you can plan for the kids and pets. With blown-in insulation in the attic, most people stay home while we work. If you're a landlord, that's worth sharing with your tenants early.
