Insulation Company in Highland, CA
Thistledown Attic Insulation is the insulation company Highland homeowners call when they need the job done right without the usual mess and surprise billing. Highland’s position at the base of the San Bernardino Mountains means attics here work harder than almost anywhere else in the Inland Empire. We’re the team that shows up on time, puts a written price in your hand before any work starts, and treats your home like it’s our own. Call (909) 768-6501 any time – a live person answers, day or night.
Why Highland Homes Are Different
Highland sits at roughly 1,200 to 1,500 feet, right where the inland valley heat meets cold air draining off the San Bernardino Mountains. That gives the community 30 to 40 degree swings between daytime highs and overnight lows, year-round. Homes built during Highland’s pre-incorporation growth boom from the 1960s through the early 1990s were typically insulated to minimum California code, on the assumption that Southern California was a mild climate. It isn’t, at least not here. We still find R-11 walls and attics with insulation no thicker than a few inches that’s been sitting untouched since the original build.
The older flatland neighborhoods south of Base Line Street tend to be the worst insulated in Highland. Foothill parcels built later often have more complex rooflines, vaulted ceilings, and awkward crawl spaces that make retrofit work slower and more detail-sensitive. And a good portion of Highland’s northern foothill sections sit in San Bernardino County’s High Fire Hazard Severity Zones, so insulation work in those adjacent neighborhoods often has to account for fire-rated assembly requirements that flatland contractors overlook until an inspector flags it. We know what Highland’s homes need before we open the attic hatch.
Our Main Highland Services
Two jobs dominate the phones for Highland homeowners: attic insulation and spray foam insulation. Here’s what each one looks like when we do it in Highland, with links to the full pages.
Attic Insulation in Highland
Most Highland attics we inspect have insulation that’s either settled, compressed, or just too thin for the climate. We remove what’s failing and install fresh material matched to your home. The dual heat and cold pattern here means air sealing matters as much as the insulation itself. Before we lay anything down, we check for gaps around penetrations, can lights, and the attic hatch – those little openings are where Highland’s overnight cold air sneaks in. Here’s the full picture on Attic Insulation in Highland.
Spray Foam Insulation in Highland
Spray foam makes sense in Highland’s more complex rooflines, vaulted ceilings, and hard-to-reach attic spaces. It seals and insulates in one pass, which is a real advantage in older additions and foothill homes with irregular framing. It also creates a continuous air barrier that keeps the heat out during Highlands summer days and holds warmth in when mountain air pools overnight. For attics in the fire hazard zones, spray foam applications need careful attention to fire-rated assembly requirements, which we always plan for before scheduling. Here’s the full guide on Spray Foam Insulation in Highland.

How We Work in Highland
Every Thistledown visit to Highland follows the same care standards, baked into the Cedarwell Care Promise that guides our whole family of companies. Before any tool comes off the truck, you have a written price – not a range, not an estimate, a number. Our technicians are background-checked and uniformed, so you know exactly who’s walking through the door. We lay drop cloths across your hallway and wear shoe covers from the front door to the attic hatch. We ask before we move or touch anything. When the job is done, we clean up like it’s our own home and hand you a photo of the finished cleanup before the van pulls away. That’s the standard on every Highland job, no exceptions.
It’s worth knowing how careful we are with products too. We install insulation from brands including Johns Manville, Knauf, and CertainTeed, and we match the material to your attic and your family. Where a pet-safe option exists, we choose it, so the dog can stay home during the work. And if something isn’t done right within 365 days, we make it right – no debate, no fine print.
Brands We Service in Highland
We work with insulation from Johns Manville, Knauf, and CertainTeed, among others. We keep common Highland attic sizes in stock locally, so most jobs start within days of the written quote, not weeks. See our brands for the full list and what each one does best.

Highland’s price drivers are specific: foothill homes with vaulted ceilings and limited attic access push labor time up, and any job in the High Fire Hazard Severity Zones may need additional fire-rated detailing that flatland homes don’t. Whatever the number is, you’ll have it in writing before any work starts. That’s not an option with us – it’s the only way we work.
