Therma-Tru Construction in Mentone, CA | Stallion Contractors
We’re Stallion Contractors, and we provide independent Therma-Tru door installation, repair, and retrofit service across Mentone, CA and nearby Therma-Tru in Yucaipa. That means we work on Therma-Tru entry systems every week, but we’re not a manufacturer affiliate or authorized dealer. What makes our Therma-Tru work different here is simple: we build and retrofit doors for Mentone’s wildland-urban interface conditions, including Chapter 7A-style ignition-resistant thresholds and ember-resistant sills that valley-floor contractors a few miles west rarely have to price in. If you need a Therma-Tru door rebuilt or replaced in the 92359 ZIP, call us at (855) 600-3192.
Why Mentone Residents Choose Us for Therma-Tru Service
Therma-Tru doors are common on Mentone homes because they hold up better than wood in dry heat and take paint well on mid-century ranchers and newer builds alike. We’ve installed and repaired the full line, from Smooth-Star fiberglass slabs to Classic-Craft and Benchmark steel units, and we know where they fail in this climate: chalking skins on south-facing entries, sills that lose seal when the ground shifts, and multi-point locks that bind after years of heat cycling. Ruben Montoya grew up in Colton and learned construction at San Bernardino Valley College before spending two decades working Inland Empire job sites. His father was a finish carpenter, which is partly why we still pay more attention to the final ten percent of a door install than most crews pay to the first ninety. We’re a full-scope general contractor, so a Therma-Tru entry we install is tied into the structure properly, not just screwed to whatever framing was already there.

Common Therma-Tru Construction Problems We Solve in Mentone
- Chalking and hairline cracks on fiberglass skins. Smooth-Star and Fiber-Classic doors facing south or west in Mentone take direct afternoon sun plus Santa Ana wind-driven grit. Over five to ten years, that combination breaks down the factory finish and opens hairline cracks. We sand, re-skin when the slab is still sound, or replace the door when the cracking has gone too far.
- Sill and weatherstrip seal failure. Mentone’s seasonal expansion and contraction, combined with fine chaparral ash during wind events, works its way under failing Therma-Tru adjustable sills. We’ve seen ember-sized debris get through gaps at the threshold that looked fine in calm weather. OEM sill and weatherstrip replacement fixes it.
- Paint blistering and edge rust on Benchmark steel doors. Older Mentone homes with wide eaves still expose steel doors to shed weather and morning condensation. Where the factory primer is breached, rust starts at the bottom corners and paint blisters along the edges. We strip, prime, and repaint, or replace the slab if the rust has perforated.
- Binding multi-point locks and hinges. A decade of dry heat cycling loosens hinge screws and dries out lock lubrication. Doors that won’t latch cleanly become a real problem during fire-season evacuation checks, when you need the door closed and locked fast. We rebuild hardware with OEM kits and re-align the slab.
- Threshold and jamb rot from hillside drainage. East-side slope lots in Mentone carry runoff toward entryways after heavy winter rain. Wood jambs and sub-sills rot faster than expected. We replace with rot-resistant framing and Therma-Tru composite sills designed for ground contact.
Therma-Tru Service in Mentone: What Local Conditions Mean for Your Equipment
Mentone sits at the foot of the San Bernardino Mountains along the Crafton Hills, in a wildfire-prone wildland-urban interface zone. That’s not a zoning footnote. It changes how exterior doors get specified and installed here. Therma-Tru entries on homes in Mentone, particularly along Crafton Hills Drive and the east-side slope lots, are increasingly being retrofitted with ignition-resistant thresholds and ember-resistant weatherstrip because the adjacent chaparral can carry fire straight into the neighborhood. A standard door sweep that works fine in Therma-Tru repair in Redlands or Loma Linda may not pass the fire-hardening expectations of a Mentone home. We recently replaced a failing Therma-Tru Fiber-Classic entry door on a 1960s ranch home off Crafton Hills Drive, where the fiberglass skin had chalked and the adjustable sill no longer sealed against wind-driven ash. Our crew installed a new Therma-Tru Smooth-Star slab with an OEM ember-resistant sill and weatherstrip kit, then finished the jamb with ignition-resistant trim to match the home’s defensible-space spec. The owner now has a door that latches cleanly and meets the fire-hardening expectations of the neighborhood.
Therma-Tru Models & Products We Service in Mentone
We work on all four major Therma-Tru product lines you’re likely to find on Mentone homes. The Smooth-Star fiberglass entry system is the one we install most often on replacements, because it takes paint well and resists the UV chalking that plagues cheaper fiberglass. Fiber-Classic doors show up on older ranch homes and hillside builds. Classic-Craft is the high-end wood-grain look we see on custom homes and additions. Benchmark steel doors are the most common on 1970s and 1980s tract housing. For parts, we use OEM Therma-Tru sills, weatherstrip, hinge kits, and multi-point lock hardware when the existing door frame and slab are still sound. Those parts are engineered to the brand’s tolerances, and aftermarket components rarely fit right. When the skin is cracked or the frame is rotted, we’ll tell you straight whether a full replacement with a new Therma-Tru unit is the better long-term spend than patching.

AfterTherma-Tru Service Pricing in Mentone
Therma-Tru door work in Mentone usually falls into one of three project types, and the price depends on scope rather than a fixed door-only rate. Here are the ranges we work within across Mentone:
| Project Scope | Typical Range |
|---|---|
| Home Addition (with Therma-Tru entry) | $45,000 – $130,000 |
| Roof Replacement (often paired with door work) | $8,000 – $20,000 |
| Full Kitchen Remodeling (including Therma-Tru rear entry) | $14,000 – $45,000 |
What drives the cost is the condition of the rough opening, whether we’re pulling permits for a structural change, and whether the existing jamb and threshold can be salvaged. A free estimate includes a site walk so we can measure the opening, check the sill, and give you a written line-item price with no change orders later. Call (855) 600-3192 to schedule yours.

FAQs – Therma-Tru Construction in Mentone
In most cases, yes. Mentone’s wildland-urban interface location means exterior door replacements often need ignition-resistant labeling and ember-resistant thresholds to satisfy Chapter 7A-style expectations. That’s not true at the same level in Therma-Tru service in Highland or Bloomington. We review your specific lot and defensible-space requirements before specifying hardware. Call (855) 600-3192 and we’ll tell you exactly what your entry needs.
Sometimes. Hairline cracks in the outer finish layer can be sanded and re-coated if the fiberglass substrate is still solid. But if the crack goes through the skin or the door has been sun-damaged for years on a south-facing Mentone entry, a new slab is usually the better spend. We’ll show you the damage before we recommend either path.
The most common cause is thermal expansion of the slab combined with frame movement from dry soil. Santa Ana conditions drop humidity fast, and the door’s dimensions shift enough to bind against the jamb. A secondary cause is the multi-point lock hardware drying out and binding internally. We fix both with alignment and OEM hardware service. If yours is sticking, call (855) 600-3192 for an inspection.
Yes, we do this regularly. We’re a full-scope general contractor, so a Therma-Tru entry installed as part of an addition, garage conversion, or full remodel gets framed, flashed, and finished by the same crew running the rest of the project. One contractor, every trade. If you’re planning an addition in Mentone, ask us to spec the doors at the same time we price the structure.
Benchmark steel doors show up constantly on 1970s and 1980s ranch homes, and Fiber-Classic is common on hillside builds from the same era. Smooth-Star is what we install most often as a replacement, because it handles Mentone’s UV exposure well and takes paint cleanly. Classic-Craft appears on custom homes and newer additions.
