If you live in Rialto, you already know the drill: an original door from 1962, a threshold that has been painted over six times, and a rough opening that does not match anything sold today. That is the job we handle most often here. We measure the opening, check the framing, and tell you exactly what it will take before anything is ordered.

Why Westlight Windows Riverside Is Rialto’s Preferred Door Installation Company

We are an independently owned and operated Kingswell location, founded in 2009 and led by Owen Satterfield. The Kingswell Guarantee is a written contract on every job: a written price before any work starts, a committed arrival window, a clean job site, and a written guarantee handed to you when the work is done. If something is not right within the guarantee period, we come back and fix it at no charge. That is the entire guarantee, not the summary.

Homeowners in Rialto call us because the first company did not show, or showed up and changed the number at the door. We do not do that. Your written price is the price. The crew arrives in uniform, background-checked, and knows Rialto’s older framing conditions. Our Door Installation team opens walls here on a regular basis and knows what to expect: undersized headers, rotted jambs, and original openings that were never flashed. That familiarity matters more than any ad budget.

We carry eight manufacturer lines, including PGT, CGI, and Therma-Tru, so you get a real product choice, not whatever the salesperson wants to unload. Every project gets the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

What We Mean By Rialto’s Older Rough Openings

Rialto’s housing stock is dominated by mid-century tract homes and older cottages, many with original aluminum-frame windows and uninsulated exterior doors that struggle with the Inland Empire’s extreme heat and occasional strong Santa Ana winds. The need for energy-efficient retrofits and wind-resistant installations is especially acute here compared to milder coastal communities. In Rialto’s older neighborhoods, you can often date a house by its window frames: aluminum sliders from the 60s and 70s, single-pane wood from the 50s. Many have never been upgraded for the local heat.

Door installation here must account for original rough openings that rarely match modern pre-hung units, a condition far more common in Rialto than in newer Inland Empire cities like Rancho Cucamonga or Fontana. A door from 1965 was not built to the same rough opening standard as a door from 2026. When we replace it, we often have to reframe the opening, add a header, or install a sill pan that was never there in the first place. This is the single biggest reason a quote moves, so we explain it upfront and write allowances into the contract. Any surprise is priced and approved in writing before we touch it.

Door Replacement in Rialto

Door Replacement in Rialto means taking out an old, often uninsulated exterior door and setting a new pre-hung unit into an opening that may not be square, may not be flashed, and may have hidden water damage behind the stucco. A straightforward replacement here typically runs $850 to $1,700 installed for a standard single entry door. The range widens when we find dry rot, termite damage, or an undersized header, which happens often enough in Rialto’s 1950s to 1970s tract homes that we factor a contingency into every contract rather than act surprised later.

Entry Doors

Most entry doors we replace in Rialto are hollow-core or worn steel units with failed weatherstripping. We install insulated steel and fiberglass options, including Therma-Tru entry doors, with new thresholds, jambs, and weatherstripping built to keep 100°F summer air outside where it belongs.

Storm and Exterior Doors

Storm doors make sense in Rialto for two reasons: they add a layer of defense against fall Santa Ana wind gusts and they cut down on dust intrusion, which every Rialto homeowner knows is a losing battle. We install storm doors with self-closing hinges and heavy weatherstripping matched to your existing entry door.

Sliding Glass Door Replacement in Rialto

Sliding Glass Door Replacement in Rialto usually means removing an original aluminum slider, often from the 1960s, that jams, leaks, or lets a visible gap of hot air through. Expect $2,800 to $5,400 for a full replacement with a new vinyl or aluminum door, depending on the opening size and whether we need to reframe and waterproof the rough opening. When we opened the wall for a sliding glass door replacement on a 1960s tract home near the Rialto Marketplace, our crew found the original aluminum frame had been set directly against untreated framing, with no sill pan or flashing, just dry rot starting behind the stucco. We replaced the rotted jamb, installed a new sill pan and waterproofed the rough opening, then set a PGT impact-rated sliding door with a Miami-Dade NOA and reframed the opening to meet current design pressure requirements.

Why Sliding Door Openings Fail Here

Original aluminum sliders in Rialto were installed without sill pans, which means any water that got past the track went straight into the wood framing. After 50 or 60 years, that framing is often soft or gone. We inspect for termite damage and dry rot before the new unit goes in, because installing a new door into compromised structure is how you end up calling us again in three years.

What We Install

We install energy-efficient sliding glass doors from ViewLux and PGT, including impact-rated models that stand up to Santa Ana winds and meet current California energy code. Low-e glass, a thin coating that reflects heat back out in summer, is worth adding on any Rialto slider.

Trusted Brands We Service in Rialto

We stock and install doors from eight manufacturer lines, so you are not forced into one brand. For Rialto’s heat and wind, we often recommend PGT and CGI for impact-rated performance, and ViewLux for a balance of thermal efficiency and price. Therma-Tru remains the go-to for entry doors. Because we have local supply relationships across the Inland Empire, we can often get parts and full door units faster than a contractor ordering from a catalog. When a Rialto homeowner needs a replacement threshold or a new slider track, we can usually have the part in hand within days, not weeks.

We never imply we service brands outside our eight lines. If you have a question about a specific manufacturer, call us and we will tell you straight whether we work with it.

Common Door Installation Problems We See in Rialto Homes

• Hidden termite damage or dry rot behind the old frame. Rialto’s older wood-framed walls have had decades of irrigation overspray and occasional winter rain to work on them. We pull the old unit and inspect the jamb and subfloor before the new door is ordered, not after it is installed.
• Undersized headers on original openings. Mid-century tract homes in Rialto often have headers that do not meet current code for the span. When we open the wall, we check the header size and add hold-downs if the existing framing will not pass a Rialto inspection.
• Openings that do not match modern pre-hung sizes. A 1960s Rialto slider may be 6 feet wide, while modern doors come in 5-foot or 8-foot widths. We reframe the opening to the correct size rather than shimming and hoping, which is what causes jamming and air leaks later.
• Failed weatherstripping and hollow-core doors on west-facing sides. The late-afternoon sun that pours through a good window is the same sun that cooks a Rialto front door every evening. We replace weatherstripping and swap hollow-core doors for insulated units to cut the cooling load.
