Retrofit insulation in Lubbock TX - added where your attic and walls run thin

Hot upstairs rooms and a power bill that keeps climbing in an older house? We check what's up there, then add insulation where it's thin or missing.

Can you add insulation to a house that already has some?

Retrofit insulation means adding insulation to the house you already live in, and in Lubbock that's usually blown-in insulation, loose fill blown through a hose, spread across the attic floor or fed through small holes into empty wall cavities.

Most calls I get for this start with a hot upstairs, a drafty room over the garage or a power bill that won't come down, in a house that already has some insulation. Usually the attic has settled thin, or it's deep in the middle and bare at the edges, or the walls were never filled at all, and it's worth knowing which before anyone adds a thing.

The price moves with the size of the attic, how many inches are already up there, whether old material has to come out first and whether the walls need filling too. The schedule turns on what I find, because if there's a roof leak or old wiring to fix first, I'll tell you, and your written estimate gives you the figure for your house before you decide anything.

What happens after you call about retrofit insulation in Lubbock?

You deal with me from the first visit to the final walk-through, so the person who looked at your attic is the one who checks the work.

I come out and look at it myself

I started as a helper on an insulation crew around Lubbock and have run this business since 2021, so I'm the one who climbs into your attic and checks the walls. I talk through what I find while I'm there, and I'll answer the same question twice if you need me to.

A written estimate you can read at home

After the visit I send a written estimate that spells out where I'd add insulation and where what you have is fine. If something like a roof leak needs fixing first, it's in there too, so nothing gets covered up.

Our own crew, then a walk-through with you

Our own crew does the work, and we're licensed and insured. When they finish, I walk the job with you so you can see what went in and where. Satisfaction guaranteed on every job.

What our retrofit insulation work covers

I start by checking what your attic and walls already have, how many inches are up there and whether it's dry and clean, because the right amount to add depends on what's already in place. Then we add insulation only where it's thin or missing, which on most older houses means the attic floor first and any empty walls after. If new siding is in your plans, it's worth timing the wall work to go with it, since the walls are easier to get at while the siding is off.

Some houses only need the top of the house done, and our attic insulation page covers that job on its own. We also install spray foam insulation, and on the visit I'll tell you plainly whether your house is better served by that or by sealing and loose fill.

  • Attic floors that are thin, uneven or bare in spots
  • Empty exterior wall cavities, filled through small holes
  • The room over the garage and upstairs rooms that run hot
  • Wall work lined up with new siding when you're planning it
  • Top-ups only where the old insulation is dry and worth keeping

How the job goes, in order

Every retrofit job runs in the same order, because the fixes underneath decide whether the new insulation does any good.

  1. Fix what's underneath first

    If the old insulation is soaked or full of droppings, it comes out, because new material laid on top just keeps the problem. A roof leak or old wiring gets sorted before we cover anything, and I'd rather tell you that than bury it.

  2. Seal the gaps

    We do the air sealing, closing gaps around can lights, pipes and the attic hatch, before any fill goes in. That way the new insulation isn't fighting a draft coming up from the rooms below.

  3. Blow in an even layer

    We carry the loose fill out to the edges as deep as the middle, since the edges are where it usually ends up thin. We keep the eave vents clear so the attic still breathes and moisture doesn't show up in the framing.

  4. Patch the walls and clean up

    Holes from wall filling get closed and smoothed so they blend back in. We clean up the hatch area and anything we tracked through, and then the job's ready for the walk-through.

Questions Lubbock homeowners ask about retrofit insulation

How much attic insulation does a Lubbock home need?

ENERGY STAR recommends R49 for an attic with no insulation and R38 for one that already has 3 to 4 inches, in climate zone 3, which a Texas energy code guide lists Lubbock in. R-value is how well insulation slows heat, so the inches already up there decide how much a job adds, and I measure that on the estimate visit.

Can you insulate existing walls without tearing them open?

Usually, yes, by drilling small holes from inside or outside, blowing fill into each empty cavity and closing the holes after. Working from outside means cutting through the water-shedding layer behind the siding, which then needs patching or replacing, so the better side depends on access and the shape that layer is in, and it's fair to ask which side suits your house. If you're re-siding anyway, ENERGY STAR recommends filling empty cavities in a wood-frame wall before the new siding goes on, and in zone 3 adding an insulating sheathing rated R5 under it, so both can happen in one project.

How much does blown-in attic insulation cost?

Across the US, installing blown-in attic insulation usually costs about $4 to $7.50 per square foot. That's a national figure, not our price, and yours depends on the size of the attic, what's already up there and whether sealing or removal comes first.

Do lead safety rules apply when insulating walls in an older home?

They can, because owners of homes built before 1980 should be aware of lead safety rules, depending on how much of the walls the work disturbs. If your house is that age, ask me how the crew will follow those rules before any wall work starts, and I'll go over it on the visit.

Can a homeowner get their own building permit in Lubbock?

In some cases, yes, since the city may issue building, plumbing and mechanical permits to owners who live in the home as their homestead, when the owner or an immediate family member does the work. That applies when your family is doing the job yourselves, not when you hire a crew.

Lubbock permits and checking who you hire

The City of Lubbock requires a permit before building, altering or repairing a structure when one of its codes covers the work. When your job needs one, we get it from the city and take care of the paperwork, and if we aren't sure, we call the city's building office and ask before we start. You can also reach the city's Building Inspection Department at 806-775-2087 or 806-775-3155 for more specific permit questions.

Texas doesn't license building contractors or remodelers, but the city requires them to register with that department, and registering takes proof of commercial liability insurance or a compliance bond, so it's a fair thing to check on anyone you hire. We're based in Lubbock and work across the city and the cities around it, including Wolfforth, Slaton, Levelland, Plainview, Littlefield and Brownfield, where most of what we see are tired older attics and rooms that never heat or cool evenly.
