Why Houston Homeowners Choose Reflectix Insulation
Woolsey Insulation Houston provides independent Reflectix insulation repair and installation across Houston, from attic radiant barriers in Meyerland ranch houses to crawl space vapor control in newer builds west of Katy. We’re not a Reflectix distributor and we’re not authorized by the manufacturer. What we are is a local Houston crew that has worked with this foil product line long enough to know exactly where it performs, where it fails, and how to fix it without voiding a warranty or wasting your money. If you have Reflectix that’s sagging, tearing, or just not doing what the box promised, call us at (903) 447-8369 for a straight answer and a written price before any work starts.
The truth about Reflectix in Houston is that it’s a specific tool for a specific job. It’s not a replacement for fiberglass or cellulose. It’s a radiant barrier and vapor control material, and the way Houston’s humidity interacts with it means installation details matter more than the product itself. We see the same mistakes repeated across the city: seams taped with the wrong tape, foil stapled flat against roof decking with no air gap, and radiant barrier that’s become a condensing surface instead of a reflector. These failures are fixable, and they’re fixable for less than most homeowners assume.
Why Trust Woolsey Insulation Houston for Your Reflectix Insulation?
Glenn Hartley, our owner, learned building science at Los Angeles Trade-Technical College and has spent more than two decades in the insulation trade. He and our Houston crews have worked on the full range of what this city throws at a house: 140°F attics in August, humidity that tests every seam and staple, and a mix of 1950s framing and 2000s construction that keeps every job different. Glenn’s rule applies to every Reflectix job we take: if we wouldn’t put it in our own attic, we’re not putting it in yours.
We stock full rolls of the common Reflectix widths in Houston: the 16-inch and 48-inch double reflective insulation, the R-21 attic unfaced rolls, and the concrete slab insulation with the white poly facing. We carry the right shears, the right staplers with 3/8-inch corrosion-resistant staples, and the right tape. That last point matters more than most homeowners realize. Reflectix seams need foil-facing tape. General-purpose duct tape fails after one Houston summer, and when a seam opens between the foil and the roof sheathing, condensation collects and the barrier stops working. Our technicians are background-checked and uniformed, and we answer the phone with a live person 24 hours a day. We’re independently owned and operated under the Kingswell banner, which means every job carries a written price before work begins and a 365-day written guarantee after it’s finished.
Common Reflectix Insulation Problems We Fix in Houston
Here’s what we actually find when we get into Houston attics and crawl spaces with Reflectix installed:
- Sagging foil under rafters. Most Reflectix in Houston attics is stapled up under the rafters as a radiant barrier. The kraft paper tabs on some product lines soften in Houston’s high attic humidity, and staples back out of old roof decking that’s been through decades of thermal cycling. The foil sags, the air gap collapses, and you lose the reflective surface that does the work.
- Failed seam tape. We see this constantly in houses across Houston. Someone installed a radiant barrier and taped the seams with general-purpose tape instead of foil tape. The adhesive dries out in the attic heat, the seams open, and condensation forms between the foil and the sheathing. The barrier goes from reflecting heat to trapping moisture.
- No air gap installation. Reflectix works as a radiant barrier because of the air space on at least one side. When it’s installed flat against a roof deck with no gap, the reflective surface has no chance to reflect. The foil becomes a conductor and actually moves heat into the attic. We see this in Houston homes where a previous contractor or DIY install pinned the foil directly to the decking and called it done.
- Condensation and mold in crawl spaces. Reflectix used around ductwork or pipes in unconditioned Houston crawl spaces can develop mold where the foil touches a cold duct and condensation has no drainage path. Houston’s humidity makes this worse than in drier climates. The foil needs proper orientation and drainage consideration, or it becomes a moisture trap.
- Crushed or delaminated sections. If Reflectix gets compressed under storage boxes in an attic or crushed during a roof repair, the air gap structure inside the material breaks down. Delaminated foil loses its reflectivity, and no amount of re-taping fixes it. Those sections need to come out and be replaced.
Reflectix Parts & Our Repair-vs-Replace Approach
We use genuine Reflectix foil and Reflectix Foil Tape for seams wherever the product is visible or part of an active radiant barrier system. For hidden installations, we may use code-approved UL-listed aluminum foil tape with equivalent adhesion and reflectivity, which keeps the job cost down without cutting corners on performance. The decision comes down to what the installation actually needs.
When we evaluate a Reflectix repair in Houston, we look at three things: whether the foil is intact, whether the air gap can be restored, and whether there’s any condensation staining or mold. Sagging foil with good reflectivity gets re-stretched, re-stapled with corrosion-resistant fasteners, and re-taped. Torn or crushed sections get replaced. Condensation-stained foil gets replaced, because the staining means moisture has already compromised the material and mold may be present. We don’t sell you a replacement when a repair will hold, and we don’t patch something that should come out. Call (903) 447-8369 and we’ll give you an honest assessment with a written price before we touch anything.
Our Reflectix Service Process – Step by Step
- 1
Attic or crawl space inspection. We measure existing insulation depth, check for air gaps on both sides of the Reflectix, inspect seam tape condition, and look for condensation staining, pest damage, or decking issues that affect the installation. In Houston’s older homes, this often means working around settled blown-in fiberglass or cellulose that has to be moved aside.
- 2
Repair or replacement with proper fastening. For repairable sections, we re-stretch the foil, fasten with 3/8-inch corrosion-resistant staples into solid decking or framing, and seal every seam and perimeter with foil tape. For replacement sections, we cut to size and match the existing product’s reflectivity and structure.
- 3
Air gap verification. We confirm the required air space exists between the foil and any surface. Without that gap, a radiant barrier does nothing. This is the step most DIY installs skip, and it’s the step that makes or breaks performance in Houston’s August heat.
- 4
Test and document. We use a surface thermometer to measure before-and-after attic temperatures when a radiant barrier repair is involved. You see the number drop. Then we walk you through what we did, what we found, and what to watch for before next summer.
Every Reflectix job gets a written guarantee. Every job, no exceptions. If something isn’t right within 365 days, we come back and fix it at no charge. That’s the Kingswell Guarantee, and it applies to Reflectix work exactly the same as every other install we do.
Reflectix Products We Service & Install in Houston
We work with the full Reflectix product range relevant to Houston homes. The Double Reflective Insulation in 16-inch by 25-foot rolls (BP24025) and the 48-inch by 50-foot rolls (BP48050) are the workhorses for attic radiant barrier and crawl space vapor control installations. The R-21 Attic Unfaced Reflective Insulation in wide rolls gets used for attic floor applications where a reflective layer complements traditional insulation. For slab and foundation work, we handle the Concrete Slab Insulation with the white poly facing on one side (ST16025). We keep stock of the common widths at our Houston shop so most repairs don’t wait on a shipment.

FAQs – Reflectix Insulation Service in Houston
Can Reflectix be used as the only attic floor insulation in Houston, or does it need to pair with fiberglass or cellulose?
Reflectix is not enough on its own for attic floor insulation in Houston. It’s a radiant barrier and vapor control product, not a thermal insulator in the same way fiberglass or cellulose is. In Houston’s climate, the long cooling season means you need both: radiant barrier under the rafters to reduce heat gain from the roof deck, and proper R-value insulation on the attic floor to slow heat moving down into the living space. If someone sells you Reflectix alone as an attic insulation solution, they’re not being straight with you. Call us at (903) 447-8369 and we’ll tell you what your attic actually needs.
Can we install Reflectix directly against the roof deck in a Houston attic to keep heat out?
Installing Reflectix flat against the roof deck with no air gap turns it into a conductor instead of a radiant barrier. The foil needs an air space on at least one side to reflect radiant heat. When it’s pinned flush to the decking, the reflective surface has no room to do its job, and heat transfers through the material into the attic. This is one of the most common mistakes we find in Houston attics, and it’s also one of the easiest to fix by re-installing with proper spacing.
What causes Reflectix to develop condensation in a Houston crawl space, and how do we fix it?
Condensation forms when the foil touches a cold surface, like a duct or pipe in an unconditioned crawl space, and Houston’s humidity provides the moisture. The foil needs an air gap and proper orientation so any condensation has a drainage path instead of collecting against the material. When we find mold on crawl space Reflectix, we remove the affected sections, address the underlying moisture source, and re-install with the reflective side positioned correctly and the necessary air space maintained.
Why do the seams on my existing attic radiant barrier keep coming apart every summer?
The seams are almost certainly taped with the wrong tape. General-purpose tape adhesives break down in Houston’s attic heat, which routinely exceeds 130°F in July and August. The seams open, air moves through, and the barrier’s effectiveness drops with every gap. The fix is to remove the failed tape, clean the foil surface, and re-tape with foil-facing tape that’s rated for high-temperature attic conditions. We do this repair regularly, and it’s typically a same-day job.
Should we remove old, torn Reflectix before replacing it, or can you install new foil over it?
It depends on the condition of the existing foil. If the old Reflectix is sagging but the foil surface is intact and clean, we can often re-stretch and re-fasten it, which saves you money. If sections are torn, crushed, or show condensation staining, those sections need to come out before new foil goes in. Installing new Reflectix over compromised material hides the problem instead of fixing it, and it can trap moisture between layers. We’ll show you exactly what we find during the inspection and recommend the repair or replacement based on what’s actually there.
How much does Reflectix insulation service cost in Houston?
Most Reflectix repairs in Houston run between $250 and $850 depending on the square footage involved, the condition of the existing foil, and whether we’re doing a repair or a full removal and replacement. Larger Houston attics with extensive damage or new radiant barrier installations across the full roof deck run higher, typically $1,200 to $3,500 for a complete installation in a 1,800 to 2,500 square foot home. These are honest ranges. The exact number comes in writing before any work starts. Call (903) 447-8369 for a free estimate with a written price, no surprises at the door.
