AfterFast, Reliable Door Replacement Across Fontana
Door replacement in Fontana typically runs $1,200 to $4,800 for an exterior entry door, and $350 to $900 per interior door, with most jobs completed in one to two days once materials arrive. That’s the honest range we quote at Juniper Windows & Doors, and we put every number in writing before a single screw turns. If you’re on the north side of town near Sierra Lakes or over by Southridge, you already know Fontana’s wind doesn’t mess around. Our crews serve Fontana daily from the Inland Empire office, and you’ll always reach a live person when you call (682) 281-2168.
Why Juniper Windows & Doors Is Fontana’s Preferred Door Replacement Company
We’ve been replacing doors since 2001 as part of the Relay Home Co. family, and the Fontana jobs stick with us because of one thing: the Cajon Pass wind corridor. A door that holds up fine in Riverside can fail inspection three miles north in Fontana if it isn’t rated for the positive and negative design pressure that San Bernardino County enforces under the 2022 California Building Code. That’s the kind of local knowledge that separates a door swap from a door replacement done right.
Our Fontana customers work with background-checked, uniformed technicians who show up with a live arrival time you can track on your phone. Before-and-after photos, a written price, and a digital invoice are standard on every job. And if something isn’t right, the 365-Day Done Right Promise covers parts and labor for a full year. In writing.
Sean Mackey leads the team with a simple standard: no vague estimates, no surprise change orders, no voicemail maze. When you call (682) 281-2168, a real person answers, 24/7.
Interior Door Replacement in Fontana
Interior Door Replacement in Fontana means pulling out an old slab or pre-hung unit and installing a new one that actually fits the rough opening, swings the right direction, and closes without dragging. In Fontana’s newer subdivisions around Sierra Lakes and the older slab-on-grade tract homes west of the 15, we see two very different framing situations, and the rough-opening check changes everything. Skip it, and the new door jamb won’t seal, which lets wind-driven dust from the Cajon Pass into hallway closets and bedrooms.
Pre-Hung vs. Slab Swaps
Most Fontana homes with original hollow-core doors are best served by a pre-hung replacement, especially on the second floor where settling has shifted jambs. A slab swap looks cheaper at first, but if the existing jamb is racked, you’ll fight that door for years.
Hardware and Hinge Upgrades
While the door is off, we check hinge screws and strike plates. Older Fontana homes often have short screws that strip out of the jamb. Three-inch screws into the framing take two extra minutes and stop a sagging door permanently.
Interior Door Installation in Fontana
Interior Door Installation in Fontana covers new construction, additions, and the case where you’re changing the floorplan entirely. We install solid-core, hollow-core, barn-style, and pre-hung doors with the same written-price rule: you know the cost before we order anything. Fontana’s ADU boom has driven a lot of this work, and the city’s inspection process for new interior work is straightforward when the rough framing is right.
New Construction and ADU Doors
If you’re finishing an ADU off Citrus Avenue or a room addition in the Northgate area, door installation has to match the plans the city approved. We work from your permit set and flag discrepancies before install day, not after the inspector leaves.
Closet and Passage Door Packages
Whole-home interior door packages are common when Fontana families buy a mid-century home and want consistent hardware and paint-grade doors throughout. We quote per opening, so you’re not paying a blended number that hides the cost of that odd-sized pantry door.
Trusted Brands We Service in Fontana
We stock and install doors from Therma-Tru, PGT, and CGI, plus hardware-matched units from ViewLux. For Fontana’s wind exposure, PGT and CGI impact-rated options are the ones we recommend most often, and our crews know exactly how to field-verify the rough opening so the unit hits its labeled design pressure. Having multiple product lines available means the right door for a Sierra Lakes entry is never a compromise. When a homeowner off Baseline needs a replacement glazed panel, we can often pull it from local stock and keep the job moving without a two-week lead time.
Common Door Replacement Problems We See in Fontana Homes
- Wind-whistling entry doors on west-facing exposures. Fontana’s afternoon gusts out of the Cajon Pass find every gap in a builder-grade jamb. A door that seals tight in the morning unloads under positive pressure by 3 p.m. We fix this with a properly rated unit and compression weather-stripping, not a thicker sweep.
- Failed inspection because the door wasn’t rated for the exposure zone. San Bernardino County checks for positive and negative design pressure compliance. Homeowners who ordered a stock door online with generic glazing end up re-ordering after the inspector flags it, which is a three-week delay.
- Settled rough openings on older slab-on-grade homes. Fontana has thousands of 1950s and 60s slab homes where the door framing has drifted over decades. Measure the existing door only and you’ll hang a unit that binds at the latch. We check the rough opening with a level before anything gets ordered.
- Unpermitted entry door swaps that surface at resale. A new front door is a visible upgrade, and in San Bernardino County, unpermitted work can complicate a sale and void wind mitigation discounts on insurance. We pull the permit and close it out properly.
Pricing for Door Replacement in Fontana, CA
Here are the real numbers for Fontana’s market. A pre-hung interior door with basic hardware runs $350 to $600 per opening. Solid-core interior doors with paint-grade finish land around $500 to $850. Exterior entry doors start around $1,200 for a basic steel unit and go to $4,800 or more for an impact-rated PGT or CGI door with multi-point locking and low-E glass. The biggest cost driver in Fontana is the wind rating. A door that meets San Bernardino County’s positive and negative design pressure requirements costs more than a stock unit, and that’s the price difference between passing inspection and re-ordering.

FAQs About Door Replacement in Fontana
Yes. Exterior door replacements in Fontana require a permit because San Bernardino County enforces the 2022 California Building Code for wind and ember-resistance on entry doors. Interior door replacement does not need a permit. We handle the permitting, scheduling, and final inspection sign-off. Call (682) 281-2168 if you want us to pull yours.
Interior doors are typically installed in one day per opening once the door is in stock. Exterior entry doors usually take one to two days, plus two to three days if a custom or impact-rated unit has to be ordered from PGT or CGI. We give you a written timeline with your quote, and you’ll see photo updates as the work progresses.
The rough opening size, the wind rating required for your exposure zone, the glass package, and the hardware. In Fontana, an impact-rated PGT door with low-E glass and a multi-point lock will always cost more than a stock steel unit off the shelf, because it’s doing a different job. We’ll walk you through exactly what your home needs and what you can skip. Call (682) 281-2168 for a written quote.
It can help. Wind-rated and impact-rated doors often qualify for wind mitigation discounts on homeowners policies in San Bernardino County, but only if the work is permitted and the right documentation is filed. We provide the paperwork your insurer needs. An unpermitted swap won’t qualify and can complicate a resale later.
Hidden framing damage is the most common item. If we open the wall and find rotted jamb studs or a sill that’s failed on a west-facing exposure, the fix adds scope. You’ll see it in photos, we’ll stop and explain it, and you approve the new written price before we touch it. No change orders appear without your sign-off. That’s the Relay Standard.
