Attic Insulation in Houston, TX
Install, top up, or tear out — we handle the whole attic.
A Houston attic runs 130 to 140 degrees on a July afternoon. When the insulation up there is thin, packed down, or twenty years past its prime, your AC fights that heat all day and you feel it on the CenterPoint bill. We’ve been working in attics across this city since 2002 — 1950s ranch homes in Sharpstown, new builds out in Katy and Cypress, two-story places in Kingwood that never cool evenly upstairs. The job is usually some mix of three things: pull out what’s failed, seal the gaps air is leaking through, and bring the R-value back up to where it belongs. We do all of it, and because we also clean the ducts and handle mold and water damage, it’s one crew and one trip instead of three.
We install and service the full range, and we match the material to the house instead of selling one product:
- Blown-in cellulose — fast, fills every gap, great for topping up a thin attic
- Batt and fiberglass — solid value, ideal when an attic floor is being added
- Open-cell spray foam — air sealing and sound control for the right applications
- Closed-cell spray foam — the highest R-value per inch and a moisture barrier
- Radiant barrier — reflects the roof heat that drives Houston attic temps
- Air sealing — closing the leaks that quietly waste a third of your cooling
- Insulation removal — old, wet, moldy, or rodent-contaminated material taken out clean
- Attic fans — including solar units to pull heat off the attic and off your AC
Wet, moldy, or contaminated insulation? That's our wheelhouse.
This is where a cleaning-and-restoration company beats an install-only outfit. After a roof leak, a burst pipe, or a slow attic drip, wet insulation can’t be dried and reused — it has to come out before mold sets in. Same with insulation a rodent has gotten into. We remove the contaminated material, treat the space the way we’d treat any mold or water-damage job, and then re-insulate. If you’re not sure what’s up there, we’ll get in the attic and tell you straight. Free estimate, no pressure. Call (832) 699-0888.For the full process, see our dedicated insulation removal in Houston page.
When the attic itself needs work — droppings, debris, or years of accumulated dust — our attic cleaning and decontamination service clears everything down to the decking before the new material goes in.

What Is R-Value, and How Much Insulation Do You Need?
R-value is just how well a material resists heat moving through it — higher number, more resistance. Houston sits in the Department of Energy’s Climate Zone 2, where attics are the priority because that’s where most of the heat gets in. Current Houston code puts the attic minimum around R-38, and plenty of homeowners go up toward R-49 when the goal is the lowest possible summer bill. The right number depends on what’s already up there and how the attic’s built, so our tech measures and tells you what you actually need — not what’s easiest to sell. We’re here for the whole thing, from the front desk to the crew in the attic. Call with any question: (832) 699-0888.
Customer Testimonials
Stay Cool with an Extreme Air Duct Attic Fan
If you live in Texas, you already know the attic is the hottest spot in the house, and that heat works against everything below it. An attic fan moves that hot air out and takes a real load off your AC. We install efficient attic fans, including solar units that run on free sunlight and cost nothing to operate once they’re up. It’s a small add-on that pairs well with new insulation — keep the heat from building up, and the insulation you just paid for does its job that much better. Call for a free estimate.
Insulation FAQ
How much insulation does a Houston attic need?
Houston is in Climate Zone 2, and current code puts the attic minimum around R-38. Many homeowners go up to about R-49 for bigger summer savings. We measure what's there and tell you the real number for your house.
Should I add insulation over the old stuff or remove it first?
If the existing insulation is dry and clean, we can often top it up. If it's wet, moldy, matted flat, or rodent-contaminated, it comes out first. We'll tell you which after we look.
Does wet or moldy insulation have to be removed?
Yes. Once insulation gets wet it loses its R-value and becomes a mold risk, and it can't be dried and reused. We remove it, treat the area, and re-insulate the same way we handle any water-damage or mold job.
Do you remove rodent-contaminated insulation?
We do. We take out the contaminated material, clean and treat the space, and install fresh insulation so you're not just covering the problem.
Will new attic insulation lower my CenterPoint bill?
In most older Houston homes, yes — the attic is where the heat gets in. Better insulation and air sealing mean your AC runs less. The savings depend on your starting point and your home.
Blown-in or spray foam for a Houston attic?
Blown-in is fast and cost-effective for topping up. Spray foam costs more but air-seals and gives the highest R-value per inch. We match the material to your attic instead of pushing one option.
Can you clean my air ducts and redo the insulation in one visit?
Yes, and that's the advantage of using us — one crew handles the ducts, the insulation, and any mold or water issues, instead of scheduling three companies.
How long does an attic insulation job take?
Most residential attics are a single day. Removal-and-replace jobs or large homes can run longer. We give you the timeline with the estimate.
Do you offer free estimates?
Yes. We get up in the attic, see what's there, and give you a straight estimate at no charge.
