What does retrofit insulation involve in an older El Paso house?
Retrofit insulation in El Paso adds insulation to a house that's already built, most often loose fill that our crew blows through a hose and spreads to an even depth across the attic floor, and sometimes into the walls. Done in the right order, it cuts drafts and helps the upstairs hold the temperature you set.
Most calls start with a hot room upstairs or over the garage, and the fix is rarely just more insulation, because fresh material over a leak or an open gap only hides it. The price moves with how many inches are already up there, how old the house is, how much air sealing the attic needs to close its gaps and whether walls are part of the job, and the schedule mostly turns on repairs that have to happen first. Your written estimate lists each of those steps, and when a permit applies, we take care of the application and the inspections.
Why El Paso homeowners call Wraptight El Paso Insulation Company for retrofit insulation
I look at every job myself
I come out to see every job and write the estimate, and our installers do the work. I check it before we leave, so the person who planned it signs off on it.
Trained on a city building crew
I learned insulation on a municipal crew where every job got written up and checked before sign-off. Since 2023 I've brought that habit to homes, so your estimate lists each step.
Licensed and insured across the line
We're licensed and insured and work in El Paso and the cities around it, in Texas and New Mexico. Permit rules change across that line, so I check your address with the right office first.
On a retrofit, the order of the work matters more than the material, so the first step is a look at your attic. Book that visit or call (915) 265-1142.
How we do retrofit insulation, step by step
I start with the attic, because whatever is wrong up there has to be fixed before anything covers it. In an older house we check the wiring early, and live knob and tube, the old wiring strung on porcelain knobs, has to be replaced or boxed in before we add anything, which is an electrician's call, so we wait for it. Next our crew seals the gaps around can lights, pipes and the hatch so the new layer isn't fighting a draft, and sets baffles, short channels at the eaves, so the vents keep breathing and the fill stays out of them. Then we blow loose fill to an even depth across the whole attic floor, as deep at the edges as in the middle and packed firm enough that it won't settle into holes. For walls, we fill each cavity through small holes, so you keep the plaster or drywall you have.
Most attics don't need foam, since sealing the gaps and topping up loose fill usually does the job for less, and that's the heart of our attic insulation work. When your ductwork runs through the attic, I lean toward spray foam insulation, which costs more but seals air while it insulates.
Seal and top up the attic
This suits most houses where the attic already has a thin or uneven layer that's still dry and clean. We seal the gaps first, then blow new fill over it to an even depth.
Walls filled through small holes
This suits older houses with empty or thin walls when you'd rather not open them up. We fill each cavity through a small hole and patch it, so the rooms stay as they are.
How do you know your house needs more insulation?
Hot rooms upstairs
The second floor or the room over the garage stays hot long after the rest of the house cools. That usually means a thin attic layer or open gaps, and the AC runs longer to make up for it.
A power bill that climbs
Your bill keeps creeping up with no change in how you live. Heat is usually getting through the ceiling or the walls, and you pay for it every month it goes on.
Thin or patchy attic layer
You can see the tops of the ceiling joists, or the old fill is flat, bare at the edges or piled in spots. Heat gets through wherever it's thin.
Drafts and cold floors
You feel air moving near outlets, around the attic hatch or over the crawl space, and the floors stay cold in winter. Gaps like those undercut any insulation until they're sealed.
What happens after you call us about retrofit insulation?
I inspect and write it up
After you call or write, we set a time for me to come out. I go through the attic, crawl space or walls and write an estimate listing each step, repairs first.
Our crew works the list
On the day of the job, our installers work from that written list in order, so fixing and sealing happen before any insulation goes in. If something new turns up, I tell you before we cover it.
We walk the finished work
When the work is done, I check it and walk it with you before we leave. You see the sealed gaps, the open eave vents and the depth across the attic.
Retrofit insulation questions we hear
These are the questions El Paso homeowners ask most before an attic or wall job. If yours isn't here, call or send the form and ask about your own house.
What is the best way to add insulation to an existing attic?
The best way is to fix any damage, seal the attic's air gaps, then add insulation, in that order. Federal checklists call for looking over the attic for water leaks, moisture, structural damage or pest damage first, so those repairs get done before anything covers them. Building science guidance adds that insulation alone saves little energy and can lead to health and durability problems, so sealing belongs in the same job.
Can my walls be insulated through small holes in El Paso?
Yes, walls with too little insulation can usually be dense-packed, filled tight with loose fill through a small hole into each cavity, cut from outside or inside, so the rooms aren't torn up. When the holes go in from inside, federal guidance calls for protecting the floor and setting up a containment enclosure so dust doesn't spread. At the estimate I'll tell you which side makes sense for your walls.
What if my attic has vermiculite insulation?
If your old fill is vermiculite, the light, pebbly gray-brown kind, attic work stops until there's a plan for it, because it may contain asbestos. EPA advises leaving it undisturbed, or having a trained professional remove it if it has to come out. I'll point it out at the estimate, and that step gets settled before we insulate.
What does attic insulation cost in El Paso?
Attic insulation in El Paso usually costs about $1,200 to $4,100 per job, which is the going range in the area, not our quote. That range covers the attic work, so wall filling, removing old material or repairs found at the inspection would show up as their own steps in your written estimate.
How do I know if my old attic insulation needs to come out first?
Old insulation usually has to come out when it's been soaked by a leak or is full of droppings, because new fill laid over it keeps the problem in your attic. Dry, clean material can usually stay and be topped up. I note which you have at the estimate, and when it has to go, we handle insulation removal first.
Do I need a permit to add insulation to my house in El Paso?
The City of El Paso requires a permit to build, alter or repair a building, and I check with the city whether your job falls under that before we start. Permit questions in El Paso begin at the city's One Stop Shop, its main intake point for building permits. The city has adopted the International Energy Conservation Code, and federal guidance says added attic insulation should meet or exceed the adopted energy code.
