Therma-Tru Construction in Burbank, CA | Penhallow Remodeling Los Angeles
We provide independent Therma-Tru door installation, repair, and refinishing across Burbank, and the short version is this: we know which fiberglass skins, frame savers, and weatherstripping kits actually hold up to Santa Ana-driven dust and 100°F summers in this city. We’re not a manufacturer-authorized outfit, and we don’t pretend to be. What we are is a local remodeling contractor that has replaced and re-hung hundreds of Therma-Tru systems in Burbank’s historic districts and hillside ranches. For Therma-Tru sales & service that respects your home’s original character, call us at (213) 277-6578 for a free estimate.
Why Burbank Residents Choose Us for Therma-Tru Service

Therma-Tru doors are fiberglass, not wood or steel, and that changes how they fail, how they get repaired, and whether a repair is even worth doing. Most handymen treat a warped Therma-Tru slab like a wood door problem. It isn’t. Fiberglass skins delaminate under UV, frames rot at the corners from irrigation overspray, and weatherstripping gets eaten by wind-driven grit. We see those exact failures every week across Burbank.
Trevor Nash, our owner, spent nearly two decades on residential and light commercial jobs across the Basin before starting Penhallow Remodeling Los Angeles. He learned construction at Los Angeles Trade-Technical College and still lives a few miles from where he grew up in the Crenshaw district. When Trevor talks about a door that’s sagging in a lath-and-plaster jamb, he’s not reading from a manual. He’s describing the third one he’s fixed this month. Our crews arrive background-checked and in uniform, every job gets a written price before work starts, and if something fails inside a year, our 365-Day Done Right Promise means we come back and fix it at no charge.

Common Therma-Tru Construction Problems We Solve in Burbank
- Warped or swollen door slabs from direct sun on west-facing entries. Burbank’s hot, dry summers punish darker Classic-Craft stains with aging clear coats. We see slabs that have moved a full 3/8-inch out of plane, which means the latch won’t seat and the door fights you every time. A refinish or slab replacement is usually the fix, not a whole new frame.
- Frame rot at the bottom corners from irrigation overspray. Drought-tolerant landscaping is everywhere in Burbank, but drip lines and sprinkler heads aimed too close to the entry keep jambs damp. Therma-Tru’s FrameSaver composite jamb material resists this far better than the original wood, and we install it as standard on replacements.
- Brittle, cracked compression weatherstripping from Santa Ana dust abrasion. Those winds carry fine grit that works into the bulb seals and chews them up over a few seasons. You’ll see light gaps around the door and feel a draft even when it’s closed. OEM weatherstripping replacement is a same-visit job for us.
- Loose hinge screws in older lath-and-plaster jambs. Many 1920s-1940s Burbank homes were never packed out for the weight of a fiberglass slab. Hinges pull loose, the door sags, and the latch misses the strike plate. We reinforce with longer screws into the framing and realign the slab.
- Sill and threshold wear that lets in dust and heat. Adjustable Therma-Tru sills settle over time. In a city where summer days routinely break 100°F, a failed threshold means your air conditioning is leaking out your front door. We replace sills and thresholds with OEM parts when available.
Therma-Tru Service in Burbank: What Local Conditions Mean for Your Equipment
Burbank’s Rancho Equestrian District is one of the few places in Los Angeles County where accessory structures like horse stables fall under the city’s rural character overlay. That means door and window trim on those structures has to match the original ranch vernacular. A standard white vinyl brickmould won’t pass review. So we regularly order Therma-Tru Fiber-Classic slabs with custom brickmould to match the existing redwood stables out there. That’s not a detail you’d know unless you’ve pulled permits in that district and sat through the design review. We have. It’s exactly the kind of Burbank-specific constraint that changes what a door job costs and how long it takes, and it’s a big part of why generic door companies stumble when they work in this city.
Therma-Tru Models & Products We Service in Burbank
We work on the full residential line: Classic-Craft American Style, Fiber-Classic Oak, Smooth-Star, and the newer Pulse series. That covers everything from a 1990s Smooth-Star on a Burbank ranch to a new Pulse entry on a Magnolia Park Spanish Colonial. We stock genuine Therma-Tru replacement weatherstripping, corner pads, and adjustable sills so we can turn most repairs around in a single visit. For discontinued Classic-Craft finish colors, we source a color-matched aftermarket fiberglass repair kit that costs 30-40% less than a factory refinish while restoring the original look. We only recommend full replacement when the slab is delaminating, the frame is rotted beyond what a FrameSaver jamb can fix, or you’re pulling permits and need to meet current energy code. This is what we mean when we say Therma-Tru sales & service done right.

FAQs – Therma-Tru Construction in Burbank
Yes, in most cases it can. We use a color-matched fiberglass repair kit that restores the factory look at 30-40% less than a factory refinish. The exception is when the clear coat has broken down so far that the fiberglass skin is taking direct UV, which causes delamination. At that point, refinishing is throwing money at a slab that needs replacement. Call (213) 277-6578 and we’ll tell you which situation you’re in after one visit.
Usually, but not always. 1930s openings in Magnolia Park tend to run slightly narrower and shorter than today’s standard rough openings. We can often shim and trim a Fiber-Classic or Smooth-Star to fit. Some openings need a header adjustment or jamb extension, which is structural work and gets a separate line item on your written estimate, never a surprise change order.
They help. The Pulse series has a polyurethane foam core that beats wood and steel for thermal resistance. In Burbank, where west-facing entries take full afternoon sun, that means a cooler interior door surface and less energy bleeding out. It won’t fix a house with single-pane windows and no attic insulation, but for the entry itself, it’s a measurable improvement.
Irrigation overspray. Burbank’s drought-tolerant landscaping still needs water, and sprinkler heads or drip emitters placed near the entry keep the bottom corners of the jamb damp for years. It rots from the bottom up, slowly. We replace with Therma-Tru FrameSaver jambs, which are composite and resist that moisture cycle. Call (213) 277-6578 for an exact fix quote.
You can replace the weatherstripping alone in nearly every case. Genuine Therma-Tru compression weatherstripping is a same-visit repair and runs $250 to $600 depending on the kit and threshold condition. We only push a new unit when the slab or frame has failed structurally. Call (213) 277-6578 and we’ll give you that answer straight.
