Therma-Tru Construction in Fontana, CA | Bradford Remodeling
We’re Bradford Remodeling, an independent remodeling company that installs and services Therma-Tru entry doors, patio doors, and door systems across Fontana and nearby cities, including Therma Tru repair in Rancho Cucamonga. We’re not authorized or sponsored by Therma-Tru. What sets our Therma-Tru work apart here is simple: we build for Fontana’s stucco-and-block housing stock and inland heat, not some mild coastal market. Call (903) 568-7222 for a straight answer on your door.
The crew at Bradford Remodeling has been installing Therma-Tru Fiber-Classic, Smooth-Star, and Classic-Craft doors in Fontana long enough to know how they behave here. Not how the brochure says they behave. How they actually behave after five summers of afternoon sun and a few Santa Ana wind events. We carry genuine Therma-Tru parts when they’re available, and we’ll tell you plainly when a door can be salvaged or when replacement is the smarter money. If you’re in Fontana-or need Riverside Therma Tru service-and your Therma-Tru door is sticking, sagging, or letting dust through the sill, we can help.
Why Fontana Residents Choose Us for Therma-Tru Service

Most Fontana homeowners don’t want a door sales pitch. They want the door to close square, latch clean, and keep the afternoon heat outside. That’s the job. Curtis Lane runs Bradford Remodeling, and he came up doing foundation work and finish carpentry across the Basin. He’s the kind of contractor who writes the scope down, prices it flat, and shows up with a crew in uniform. Fontana homeowners have told us that’s rare, and we take that as a reason to keep doing it.
We’re familiar with every Therma-Tru line you’re likely to have on a Fontana home, from older Fiber-Classic woodgrain slabs that have chalked in the sun to Smooth-Star doors that just need hinge adjustment and a new sweep. We stock common weatherstripping profiles, sill pans, and lock hardware so we’re not waiting on a parts truck from out of state. And when OEM parts are backordered, we’ll tell you what the aftermarket option costs and how it compares, before any work starts. That’s part of The Garrison Standard we operate under: every price in writing, every guarantee spelled out, no surprises at the punch list.

Common Therma-Tru Construction Problems We Solve in Fontana
- Doors that stick or rub in the heat. Fontana summers push past 100 degrees, and Therma-Tru fiberglass slabs expand. We see rub marks along the top of the door and latch bolts that no longer line up with the strike plate. The fix is usually hinge adjustment or a slight re-shim of the frame, not a new door.
- Chalking and fading on south- and west-facing doors. Therma-Tru Fiber-Classic woodgrain finishes take a beating in Fontana’s UV. The door face that catches afternoon sun can fade to a dull haze. We can refinish some slabs, but when the factory finish is too far gone, we’ll tell you replacement beats repeated repainting.
- Drafty sills and worn weatherstripping. Hard water from sprinklers and Fontana’s fine dust degrade Therma-Tru door gaskets faster than you’d expect. You’ll feel a draft at the bottom of the door, or see daylight under the sweep. We replace sills and weatherstripping as a targeted repair, often the same morning.
- Loose or corroded multi-point hardware. Santa Ana winds carry dust into hinges and lock mechanisms. Over time, Therma-Tru multi-point locks can loosen or bind. We disassemble, clean, and re-torque hardware where possible, or replace components with OEM parts when they’re shot.
- Water staining at the threshold. Wind-driven rain against a Fontana front door will find any gap in the sill pan. We pull the threshold, inspect the flashing, and rebuild the sill detail so water moves away from the subfloor instead of into it.
Therma-Tru Service in Fontana: What Local Conditions Mean for Your Equipment

Many Fontana homes were built in the 1980s and 1990s with stucco walls and block fence lines. That’s not a side note; it’s the whole game for door work. Therma-Tru door installations here often require careful flashing and sill pan detailing to handle wind-driven rain and Santa Ana winds, unlike milder coastal markets where a stock sill cap usually holds up. We learned this the hard way on a job in the Hunter’s Ridge neighborhood of Fontana: the original Therma-Tru Fiber-Classic on a west-facing entry had warped and was sticking in its frame after years of sun and wind. We pulled the old door, installed a new Smooth-Star with a reinforced sill and new weatherstripping, then re-set the hinges and strike plate so it latched without a shoulder shove. Stucco homes don’t forgive sloppy flashing. Block walls don’t either. So we build the opening right before we hang the door.
For Fontana homeowners, that means the door you get installed by Bradford Remodeling is set up for the house it’s going into, not just the door model you picked. We check the substrate, the sill elevation, the sun exposure, and the prevailing wind direction. Then we write the scope. Straight number, real scope, no surprises at the punch list.
Therma-Tru Models & Products We Service in Fontana
We also handle Therma Tru in San Bernardino, and we install and service the Therma-Tru lines most common on Fontana homes: Fiber-Classic smooth and woodgrain entry doors, Smooth-Star fiberglass doors, Classic-Craft American Style and Rustic Style doors, and Therma-Tru patio and French door systems. Parts approach is straightforward: genuine Therma-Tru locks, hinges, sills, and glass frames when available, and quality aftermarket components when OEM parts are discontinued or backordered. We keep common weatherstripping and hardware stocked locally so a Fontana service call doesn’t turn into a two-week wait.
If you need work on any of these lines, call (903) 568-7222. We’ll tell you what we’re working with and what the repair or replacement path looks like.

AfterTherma-Tru Service Pricing in Fontana

Here’s what Therma-Tru door work costs in Fontana, in writing:
| Service | Price Range |
|---|---|
| Therma-Tru entry door installation (standard size, like-for-like replacement) | $4,500 – $15,000 |
| Weatherstripping and sill replacement for Therma-Tru doors | $400 – $1,800 |
What drives the cost? Door model, size, whether the frame needs rebuilding, and whether we’re dealing with stucco or block around the opening. A like-for-like replacement on a standard 36-inch entry is on the lower end. A Classic-Craft door with sidelites and new flashing on a southwest-facing Fontana home runs higher. Every estimate includes a written line-item price before work starts. No numbers that move at the door. We also provide Therma Tru repair in Ontario.

FAQs – Therma-Tru Construction in Fontana
Can you repair a Therma-Tru door that sticks or won’t latch in Fontana’s heat?
Yes. Most sticking doors in Fontana are a hinge and frame alignment issue, not a door failure. We adjust hinges, re-shim the frame if needed, and re-set the strike plate so the latch drops in clean. If the slab itself is warped, we’ll tell you that too. Call (903) 568-7222 and we’ll take a look.
How do I know if my Therma-Tru door needs replacement instead of repair?
If the frame is rotted, the slab is cracked or delaminating, or the cost of repeated repairs passes half the price of a new door, replacement is the better call. We’ll give you both numbers and you decide. No pressure either way.
Do you install Therma-Tru doors in Fontana’s older stucco and block homes?
We do, and that’s most of what we see in Fontana. Stucco and block openings need proper flashing and sill pan work, especially on windward walls. We build that into the scope from the start, so the door doesn’t leak or bind a year later.
What Therma-Tru door lines work best for Fontana’s inland climate?
We typically recommend Smooth-Star or Classic-Craft doors for Fontana’s sun and heat. They hold their finish longer than older woodgrain Fiber-Classic slabs on west-facing exposures. We’ll match the line to your sun exposure and budget.
Can you replace just the weatherstripping or sill on my Therma-Tru door?
Yes. Weatherstripping and sill replacement runs $400 to $1,800 depending on the door and how much of the threshold we need to rebuild. We stock common profiles, so it’s often a one-visit fix. Call (903) 568-7222 for a written quote.
