AfterFast, Reliable Windows & Doors Across Ontario
Windows and doors in Ontario, CA take a beating from the sun, the Santa Ana winds, and the temperature swings between July’s 108° days and January’s cold snaps. A window replacement across Ontario typically runs $4,500-$15,000 depending on the count and frame material, while a full impact window installation lands between $8,000-$25,000. Our crews work across all four Ontario ZIP codes (91764, 91798, 91758, 91761), from the craftsman bungalows near Euclid Avenue to the new-tract homes in Ontario Ranch. Call (877) 610-1318 and you’ll get Tom Barrett or one of his sons on the line, not a call center.
Why Barrett & Sons Construction Is Ontario’s Preferred Windows & Doors Company
We’ve been around since 1998 and we’re still owner-operated. Tom Barrett’s name, address, and license number are published and verifiable. Ask anyone on your street, or look up the license number yourself. That matters in Ontario, where homeowners keep getting burned by out-of-area crews that quote one number over the phone and hand over a different invoice at the door. We don’t do that - and we don’t upsell you into Home Additions & ADU - Ontario work you didn’t ask for, either.
Every Windows & Doors job in Ontario gets a written scope, written allowances, and written change orders before anything changes. No surprises. If something’s wrong after the job, the 90-Day Done Right Promise means one call brings Tom back. You won’t miss that in the fine print because it’s on the front of every contract.
Ontario homeowners between 50 and 70 have dealt with enough contractors who won’t answer the phone after the check clears. We answer live, 24/7. Our crews are background-checked and uniformed, and most days the Barrett sons are on-site themselves. We also serve the broader Windows & Doors in Ontario area from our Inland Empire office, so scheduling is fast and spare parts don’t sit on a truck coming from two counties away.
Our Windows & Doors Services in Ontario
Window Installation
New window installation in Ontario usually means swapping out aging single-pane aluminum frames in the older core neighborhoods, or adding better glass packages to post-2010 production homes in 91761. On the older bungalows near the 91764 ZIP, we routinely find original sash weights and plaster returns that need careful retrofitting. On newer Ontario Ranch homes, the work is more about upgrading builder-grade vinyl to something that actually insulates against the summer heat. Both jobs get permits pulled and inspections signed.
Door Installation
Front doors in Ontario take direct afternoon sun and occasional wind-driven dust from the Cajon Pass. We install steel and fiberglass entry doors that won’t warp or swell, plus interior doors for renovations across the city. If you’re already redoing the exterior, we also handle Fence Installation in Ontario so the whole property line matches.
Window Replacement
Replacement windows in Ontario typically cost $4,500-$15,000 for a full house, depending on how many openings and what frame material you choose. The old wood sashes in the 1920s-1950s craftsman homes near downtown can’t be saved; they’re dried out, painted shut, and leaking conditioned air straight into the Inland Empire summer. We replace them with vinyl or fiberglass units sized to the existing rough openings, and we pull permits so the inspector signs off on the flashing and egress.
Impact Windows & Doors
Impact windows in Ontario aren’t required by code the way they are in Florida, but plenty of homeowners ask for them anyway. The Santa Ana winds through the Cajon Pass can hurl debris hard enough to crack standard glass, and the extra laminate layer also cuts the 110° heat gain noticeably. A full impact window package in Ontario runs $8,000-$25,000. We install PGT and CGI impact units, plus impact sliding glass doors for the patio.

Trusted Brands We Service in Ontario
We install and service Simonton, Ply Gem, and PGT windows and doors across Ontario, plus Dvele in Ontario for clients looking at premium prefab options. These are brands with published specs and warranties you can look up yourself, not mystery product off a white van. For Ontario’s older homes we keep a deep inventory of replacement hardware, balances, and weatherstripping for common Simonton and Ply Gem lines, so service calls don’t drag out waiting on a warehouse in another state. If your existing windows are beyond repair, we’ll quote a replacement in writing before any work starts.
Common Windows & Doors Problems We See in Ontario Homes
- Sun-baked vinyl and warped sashes. In Ontario’s older core (91762, 91764), decades of direct Inland Empire sun leaves vinyl frames chalked and brittle, and wood sashes so dried out they rattle in the wind or refuse to open. We replace them before the glass starts moving inside the frame.
- Failed seals and fogged glass in newer tracts. Ontario Ranch homes built after 2010 got builder-grade insulated units that often lose their argon fill within five to eight years. The fog between the panes is a failed seal, and the fix is a new sash or full unit, not a band-aid.
- Front doors swollen from heat cycling. Steel and wood entry doors in Ontario expand and contract with the 40-plus degree daily swing, especially on the south and west exposures. We see doors that stick in summer and leave gaps in winter, which also means air leakage all year.
- Poor original flashing on cut-and-filled lots. The newer pads in 91761 sit on compacted fill from the old vineyard and dairy land, and differential settlement can shift door frames just enough to break the weather seal. We re-hang and re-flash those doors so they close square and keep the wind out.
Pricing for Windows & Doors in Ontario, CA
Window replacement in Ontario runs $4,500-$15,000 for a typical single-family home, broken down below. Impact window installation lands between $8,000-$25,000. Entry door installation typically runs $1,500-$5,000 depending on material and whether the frame needs work. The biggest cost drivers are the number of openings, the frame material (vinyl is the value pick, fiberglass sits mid-range, wood-clad costs the most), and whether your existing rough openings are square enough to accept standard sizes or need custom fabrication. Many homeowners doing Ontario Kitchen Remodeling at the same time bundle the window package for better scheduling. Every quote is a written line-item estimate, and any change is a written change order before work proceeds. Call (877) 610-1318 to schedule your free estimate.

FAQs - Windows & Doors in Ontario
We typically get to Ontario within 24-48 hours for an estimate, and we schedule from our Inland Empire office so we’re already close by. Call (877) 610-1318 and we’ll give you a real time window, not an “eventually” promise.
Yes. We work in all four Ontario ZIP codes: 91764 (downtown and older neighborhoods), 91798 (Ontario International Airport area), 91758 (central Ontario), and 91761 (Ontario Ranch and the southern growth zone).
Pricing is effectively the same across Ontario, Montclair, Upland, Chino, and Claremont for windows and doors; if you’re also looking at Ontario Driveway & Pavers work, that’s quoted separately. The variable isn’t the city, it’s your home’s age and framing. Older Ontario homes with non-standard rough openings cost more in labor than newer tract homes with consistent dimensions. We’ll quote you a fixed price regardless of the neighborhood.
Yes. Any job that requires a permit under the California Building Code gets one, and the inspector signs off before we consider the job done. The permit inspector works for you, not for me. That’s why I like him.
Every job carries the manufacturer’s warranty on the windows and doors themselves, plus our 90-Day Done Right Promise in writing: if it’s not done right, call Tom and he comes back. One call and it’s handled. For an exact quote on your Ontario home, call (877) 610-1318. Estimates are free, and if you have another company’s written estimate, bring it in for a free second opinion.
