Highlands sits along the San Jacinto River, where humidity from the bayou and airborne particulates from the Ship Channel chemical corridor work against attic insulation year-round. We know these homes. We know that a ranch on River Road needs something different than a new build off Crosby-Lynchburg. And we know how to get it done in one trip.
Why Thistledown Insulation Houston Is Highlands’s Preferred Attic Insulation Company
We’re part of the Cedarwell family of Attic Insulation companies, founded in 2003. Every technician who walks through your door in Highlands is background-checked, uniformed, and trained to our Cedarwell Care Promise: shoe covers at the door, drop cloths down your hallway, a photo of the clean-up before we leave. No exceptions.
Highlands homeowners call us because the heat here doesn’t mess around. Attic temperatures routinely exceed 140°F near Galveston Bay in July and August. That kind of heat compresses blown-in fiberglass, bakes batts into thin mats, and makes the upstairs feel like a sauna. Our crews have spent enough afternoons in Highlands attics to know exactly what works – and what’s already failed in the house next door.
We answer every call live, 24 hours a day. When you call about attic insulation in Highlands at 2 a.m. because you just found rodent damage in a pier-and-beam home off Wallisville Road, a person picks up. Not a voicemail tree.
Attic Insulation Removal in Highlands
Attic insulation removal in Highlands is what we do when old fiberglass has turned into dust, when rodents have torn batts into scraps, or when a roof leak soaked everything and left mold behind. Older Highlands homes – especially the mid-century ranches off River Road and the manufactured homes on larger lots along East Wallisville – often still have their original blown-in fiberglass from 40 or 50 years ago. That material is compressed and dirty and holds almost no R-value. We vacuum it out, bag it, and haul it away. Removal in Highlands typically runs $0.60 – $1.20 per square foot, and on a 1,500-square-foot attic that means roughly $900 – $1,800 before new insulation goes in.
When Removal Makes Sense
Removal isn’t automatic. If the old fiberglass is dry, settled but intact, and free of pests, we can often blow new insulation right over it – that’s a top-up, and it saves real money. But when Highlands humidity has soaked the underside of a roof and left insulation matted and moldy, or when raccoons tore through the batts and left droppings, covering it up would be a bad insulation job and a health problem. We remove it. The decision is explained honestly, in plain English, before you spend anything.
Pier and Beam Removal Work
Highlands’s older riverside homes sit on pier-and-beam foundations, which means the attic is part of a bigger airflow picture. We see batts that rodents have dragged out of place, materials stained from years of condensation, and old Kraft paper facings that crumble when touched. On these homes, removal usually pairs with air sealing around can lights, the attic hatch, and any plumbing penetrations. Price is quoted upfront after we actually look at the attic – not over the phone from a formula.
Blown In Insulation in Highlands
Blown in insulation in Highlands homes is the workhorse. We blow fiberglass – typically Owens Corning AttiCat or CertainTeed InsulSafe – to R-38 or R-49 depending on the attic. In Highlands, where summer attic temperatures hit 140°F, we recommend R-49 for anyone who can fit it. Blown-in fiberglass runs about $1.50 – $2.80 per square foot installed, so a 1,500-square-foot Highlands attic lands between $2,250 and $4,200. You get the exact number in writing before work starts, no ifs.
Fiberglass vs. Cellulose in Bayou Humidity
Near the San Jacinto River, humidity is the deciding factor. GreenFiber cellulose insulation settles more than fiberglass and absorbs moisture faster, which makes it a poor match for some Highlands attics. We stock both and recommend based on your roof’s ventilation and the house’s age – if the attic venting is good, cellulose can work; if it’s marginal, fiberglass with proper baffles is the safer call. We’ll show you the difference while we’re in the attic.
One Trip on Acreage Properties
Highlands has working-class acreage and larger lots than Baytown or Pasadena, and a lot of those homes have detached workshops, garage apartments, or additions with their own attics. We bring enough material and enough crew to knock out the main house and the outbuildings same day. That matters when you’ve taken a day off work and don’t want a second appointment two weeks out.
Trusted Brands We Service in Highlands
We install and service eight brands – Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber – because no one product fits every attic. In Highlands, we lean on CertainTeed blown-in fiberglass for dry, well-vented attics, Demilec closed-cell spray foam for pier-and-beam homes and areas with rod-damage or high humidity, and Icynene open-cell where air sealing and sound control matter as much as R-value. Products are matched to your attic and your family – pet-safe options included where a choice exists. We carry common materials on every Highlands job, so we don’t have to leave mid-day for supplies.
Common Attic Insulation Problems We See in Highlands Homes
- Radiant barrier delamination from river humidity. The persistent moisture near the San Jacinto River weakens the adhesive on older radiant barrier foil. It peels off rafters in sheets, effectively doing nothing. Proper stapling, not adhesive, fixes this.
- Settled and compressed blown-in fiberglass. Extreme attic heat above 140°F accelerates settling, which cuts R-value significantly within 10 years. The attic might look full but test like R-11. We pull samples and show you before touching anything.
- Rodent-torn batt insulation in pier-and-beam homes. Riverside neighborhoods like the older streets off River Road have crawlspace access points that invite rats and squirrels. They tear batts, scatter material, and create cold spots at exterior walls. Replacement with closed-cell foam or rigid board where possible is the durable fix.
- Corroded duct straps and metal fasteners. Chemical particulate drift from the Ship Channel plus high humidity corrodes attic hardware faster than inland. Ducts sag, straps snap. When we replace insulation, we flag any failing hardware – before it drops onto your ceiling.

FAQs About Attic Insulation in Highlands
Two local conditions work together: extreme heat from the humid subtropical climate pushes attic temperatures past 140°F, which settles and compresses fiberglass quickly, and chemical particulates from the Ship Channel corridor accelerate corrosion of metal fasteners, duct straps, and radiant barrier adhesive. Insulation in Highlands often loses meaningful R-value within a decade. You’ll see it in a ranch on River Road faster than a newer build off Crosby-Lynchburg. If your upstairs runs hot by 4 p.m., call (430) 226-1334 and we’ll inspect what’s actually up there.
Yes, when installed correctly, a radiant barrier can cut attic temperatures by 20 – 30°F and is especially effective on Highlands’s older ranch homes with dark shingle roofs. But normal radiant barrier foil installed with adhesive will delaminate within a few years due to persistent humidity near the San Jacinto. We staple barrier to the rafters, not glue it, and it lasts. The cost runs about $0.80 – $1.40 per square foot installed, and it makes blown-in fiberglass perform noticeably better.
Closed-cell spray foam, usually Demilec, is the best fit for pier-and-beam homes near the river because it adds structural rigidity, blocks moisture, and resists rodent damage that batt insulation cannot withstand. It costs more – $2.60 – $4.50 per square foot – but in riverside homes where humidity is relentless and rodent entry points are plentiful, replacing torn batts every five years costs more in the long run. We’ll walk you through both costs and let you decide with real numbers.
Prevention is about ventilation and air sealing, not the insulation itself. We install baffles at every eave to keep air moving, seal around can lights and the attic hatch, and ensure bathroom fans vent out through the roof – not into the attic. In Highlands homes where those steps are done right, we don’t see mold in insulation. If you already have mold, removal first, then we correct the ventilation. Call (430) 226-1334 and describe what you smell – we’ll tell you over the phone whether an inspection is urgent.
Many do, especially if the original blown-in fiberglass has compressed into a thin mat or if rodents have been active in the attic. But not all – if the old material is dry and intact, a top-up over the existing insulation can save you $1,000 or more. The only way to know is a 30-minute inspection. We’ll show you samples, explain what R-value your attic currently holds, and give you the written price for whichever route makes sense.
